Three Exciting Ways to Protect Forests With Remote Sensing

Forests cover one third of the Earth’s land mass and are home to more than 80% of the terrestrial species of animals, plants and insects. However, 13 million hectares of forest are destroyed each year. The United Nations International Day of Forests took place recently, on 21st March, to raise awareness of this vital resource.

Three remote sensing applications to help protect forests caught our eye recently:

Identifying Diseased Trees
In the March issue of Remote Sensing, researchers from the University of Leicester, (Barnes et al, 2017), published a paper entitled ‘Individual Tree Crown Delineation from Airborne Laser Scanning for Diseased Larch Forest Stands’. It describes how the researchers were able to identify individual trees affected by larch tree disease, also known as phytophthora ramorum.

This fungus-like disease can cause extensive damage, including the death, and diseased trees can be identified by defoliation and dieback. Airborne LiDAR surveys were undertaken by the company Bluesky at an average altitude of 1500 m, with a scan frequency of 66 Hz that gave a sensor range precision within 8 mm and elevation accuracy around 3–10 cm.

Remote sensing has been used to monitor forests for many years, but using it to identify individual trees is uncommon. The researchers in this project were able to successfully identify larch canopies partially or wholly defoliated by the disease in greater than 70% of cases. Whilst further development of the methodology will be needed, it is hoped that this will offer forest owners a better way of identifying diseased trees and enable them to respond more effectively to such outbreaks.

Monitoring Trees From Space
An interesting counterpoint to work of Barnes et al (2017) was published by the journal Forestry last month. The paper ‘Estimating stand density, biomass and tree species from very high resolution stereo-imagery – towards an all-in-one sensor for forestry applications‘ written by Fassnacht et al (2017).

It describes work undertaken to compare the results of very high resolution optical satellite data with that of airborne LiDAR and hyperspectral data to provide support for forestry management. The team used WorldView-2 images, of a temperate mixed forest in Germany, with a 2m pixel size, alongside a LiDAR DTM with a 1 m pixel size. This data was then used to estimate tree species, forest stand density and biomass.

They found  good results for both forest stand density and biomass compared to other methods, and although the tree classification work did achieve over eighty percent, this was less than achieved by hyperspectral data over the same site; although differentiation of broadleaved and coniferous trees was almost perfect.

This work shows that whilst further work is needed, optical data has the potential to offer a number of benefits for forestry management.

Monitoring Illegal Logging
Through the International Partnership Programme the UK Space Agency is funding a consortium, led by Stevenson Astrosat Ltd, who will be using Earth Observation (EO) data to monitor, and reduce, illegal logging in Guatemala.

The issue has significant environmental and socioeconomic impacts to the country through deforestation and change of land use. The Guatemalan government have made significant efforts to combat the problem, however the area to be monitored is vast. This project will provide a centralised system using EO satellite data and Global Navigation Satellite Systems (GNSS) technology accessed via mobile phones or tablets to enable Guatemala’s National Institute of Forestry (INAB) to better track land management and identify cases of illegal logging.

Overall
The protection of our forests is critical to the future of the planet, and it’s clear that satellite remote sensing can play a much greater role in that work.

Supporting Uganda’s Farmers

Map of Uganda showing vegetation productivity. Underlying data is the MODIS 2014 NPP Product, MOD17 – Zhoa et al. (2005).

Uganda is a landlocked country of just over 240,000 square kilometres. Agriculture is a key element of the country’s economy and was responsible for 23% of gross domestic product in 2011 and almost half the country’s exports the following year. According to the Food & Agriculture Organisation of the United Nations, 80% of the population relies on farming for its livelihood.

It has an equatorial climate, with regional variations, although recent recurrent dry spells have impacted on crop and livestock productivity. Pixalytics is delighted to be part of a consortium led by the RHEA Group, working with the Ugandan Ministry of Water and Environment and local NGOs to develop a Drought and Flood Mitigation Service (DFMS) to give practical information to help local communities respond to the effects of climate change.

Using computer models populated with satellite, meteorological, water resources and ground based data an innovative Environment Early Warning Platform will be developed to provide Ugandan farmers, via local NGO organisations, with forecasts throughout the growing seasons to enable them to take actions to maximise their crop yield.

Pixalytics, along with fellow consortium member, Environment Systems, are responsible for the Earth Observation data in the project. We’ll be looking at variety of optical and radar data to provide information about flood and drought conditions alongside crops and their growing conditions.

The project should benefit local communities by:

  • Improving the ability to forecast and mitigate droughts and floods on a local actionable scale.
  • Allowing NGOs to target resources saving time, money and lives.
  • Allowing farmers to improve their lives and better protect their livestock and crops.

Alongside ourselves, and RHEA Group, our consortium includes Environment Systems, Databasix, AA International, AgriTechTalk International, HR Wallingford, UK Met Office, Mercy Corps, and Oxford Policy Management. We will also work with international partners, including the Uganda Government Ministries, Kakira Sugar Company, and the NGO Green Dreams/iCOW. The first of a number of visits to Uganda took place last week, where we had the opportunity to make lots of local contacts and meet some of those whom we hope to benefit from this work.

This work is part of the UK Space Agency’s International Partnership Programme and ours is one of 21 projects chosen to provide solutions to local issues in counties across Africa, Asia, Central and South America.

This is a really exciting project to be involved with, and we’re looking forward to providing useful information to local farmers to allow them to take real and meaningful action to enhance the productivity, and protection, of their livestock and crops.

World Record Satellite Launch

Next week the Indian Space Research Organisation (ISRO) plans to launch 104 satellites in one go aboard its Polar Satellite Launch Vehicle (PSLV-C37) that will take off from Satish Dhawan Space Centre in Sriharikota, India.

To give an idea of the enormity of what ISRO is attempting, the current world record for satellites launched in a single mission is 37 by Russia in 2014. In addition, over the last fifty years the average number of objects launched in space in an entire year is only 138, according to the Online Index of Objects Launched into Outer Space maintained by the United Nations Office for Outer Space Affairs (UNOOSA). Furthermore these figures reveal this single mission will exceed the number of objects launched into space for the twelve months of 1996 and for the years 2001 to 2006 inclusive.

This mission was originally planned to launch 83 satellites, then an additional 20 were added to the payload and finally a further nano-satellite was squeezed in. Of these 104 satellites, 3 will be Indian satellites and the remainder will be small satellites from countries including Germany, Israel, Kazakhstan, Netherlands, Switzerland, and the US.

One of the key challenges is to ensure that they do not collide. ISRO plans to achieve this by changing the degree of angle for each batch of satellites launched. It is expected that the entire batch of satellites will be launched within 90 minutes.

This launch is a really exciting one for the Earth Observation community because it includes:

  • Cartosat 2D is the next satellite in India’s Cartosat mission. These satellites carry both high resolution multi- spectral imagers and a panchromatic camera, and the mission focus is cartography. It has a sub-metre spatial resolution, a 10 km swath and a revisit period of four days. This is the primary payload, and will be the heaviest satellite on the launch vehicle at 730 kg.
  • Planet’s Flock 3p which consists of 88 satellites, and will be the largest constellation of satellites ever launched.

Planet was in the news last week as it confirmed it had completed the purchase of satellite imaging company Terra Bella from Google. Terra Bella’s SkySat’s fleet of high resolution satellites will complement the existing global coverage of Planet’s existing courser resolution fleet. When combined with the new satellites, this will help Planet to achieve their aim of imaging the entire globe every day. Thereby, offering a wide range of potential capabilities for Planet in the satellite data reseller/supplier market.

ISRO’s launch is currently scheduled for February 15th and will demonstrate a new level of efficiency for cubesats; something that is becoming increasingly important. We’ll be watching closely, and wish them luck.

Goodbye to EO-1

In contrast to our previous blog, this week’s is a celebration of the Earth Observing-1 (EO-1) satellite whose death will soon be upon us.

EO-1 was launched on the 21st November 2000 from Vandenberg Air Force Base, California. It has a polar sun-synchronous orbit at a height of 705 km, following the same orbital track as Landsat-7, but lagging one minute behind. It was put into this orbit to allow for a comparison with Landsat 7 images in addition to the evaluation of EO-1’s instruments.

It was the first in NASA’s New Millennium Program Earth Observing series, which had the aim of developing and testing advanced technology and land imaging instruments, particularly related to spatial, spectral and temporal characteristics not previously available.

EO-1 carries three main instruments:

  • Hyperion is an imaging spectrometer which collects data in 220 visible and infrared bands at 30 m spatial resolution with a 7.5 km x 100 km swath. Hyperion has offered a range of benefits to applications such as mining, geology, forestry, agriculture, and environmental management.
  • Advanced Land Imaging (ALI) is a multispectral imager capturing 9 bands at 30 m resolution, plus a panchromatic band at 10 m, with a swath width of 37 km. It has the same seven spectral bands as Landsat 7, although it collects data via a different method. ALI uses a pushbroom technique where the sensor acts like a broom head and collects data along a strip as if a broom was being pushed along the ground. Whereas Landsat operates a whiskbroom approach which involves several linear detectors (i.e., broom heads) perpendicular (at a right angle) to the direction of data collection. These detectors are stationary in the sensor and a mirror underneath sweeps the pixels from left to right reflecting the energy from the Earth into the detectors to collect the data.
  • Atmospheric Corrector (LAC) instrument allows the correction of imagery for atmospheric variability, primarily water vapour, by measuring the actual rate of atmospheric absorption, rather than using estimates.

The original EO-1 mission was only due to be in orbit only one year, but with a sixteen year lifetime it has surpassed all expectations. The extension of the one year mission was driven by the Earth observation user community who were very keen to continue with the data collection, and an agreement was reached with NASA to continue.

All the data collect by both Hyperion and ALI is freely available through the USGS Centre for Earth Resources Observation and Science (EROS). At Pixalytics we’ve used Hyperion data for understanding the capabilities of hyperspectral data. The two images shown in the blog are a subset of a scene acquired over fields in South America, with image to the right is a pseudo-true colour composite stretched to show the in-field variability.

Whereas the image at the top is the hyperspectral data classified using a statistical procedure, called Principle Components Analysis (PCA), which extracts patterns from within the dataset. The first three derived uncorrelated variables, termed principle components, are shown as a colour composite.

Sadly, satellites cannot go on forever, and EO-1 is in its final few weeks of life. It stopped accepting data acquisition requests on the 6th January 2017, and will stop providing data by the end of February.

It has been a great satellite, and will be sadly missed.

Earth Observation Looking Good in 2017!

2017 is looking like an exciting one for Earth Observation (EO), judging by the number of significant satellites planned for launch this year.

We thought it would be interesting to give an overview of some of the key EO launches we’ve got to look forward to in the next twelve months.

The European Space Agency (ESA) has planned launches of:

  • Sentinel-2B in March, Sentinel-5p in June and Sentinel-3B in August – all of which we discussed last week.
  • ADM-Aeolus satellite is intended to be launched by the end of the year carrying an Atmospheric Laser Doppler Instrument. This is essentially a lidar instrument which will provide global measurements of wind profiles from ground up to the stratosphere with 0.5 to 2 km vertical resolution.

From the US, both NASA and NOAA have important satellite launches:

  • NASA’s Ionospheric Connection Explorer (ICON) Mission is planned for June, and will provide observations of Earth’s ionosphere and thermosphere; exploring the boundary between Earth and space.
  • NASA’s ICESat-2 in November that will measure ice sheet elevation, ice sheet thickness changes and the Earth’s vegetation biomass.
  • In June NOAA will be launching the first of its Joint Polar Satellite System (JPSS) missions, a series of next-generation polar-orbiting weather observatories.
  • Gravity Recovery And Climate Experiment – Follow-On (GRACE_FO) are a pair of twin satellites to extend measurements from the GRACE satellite, maintaining data continuity. These satellites use microwaves to measure the changes in the Earth’s gravity fields to help map changes in the oceans, ice sheets and land masses. It is planned for launch right at the end of 2017, and is a partnership between NASA and the German Research Centre for Geosciences.

Some of the other launches planned include:

  • Kanopus-V-IK is a small Russian remote sensing satellite with an infrared capability to be used for forest fire detection. It has a 5 m by 5 m spatial resolution over a 2000 km swath, and is planned to be launched next month.
  • Vegetation and Environment monitoring on a New MicroSatellite (VENµS), which is partnership between France and Israel has a planned launch of August. As its name suggests it will be monitoring ecosytems, global carbon cycles, land use and land change.
  • KhalifaSat is the third EO satellite of United Arab Emirates Institution for Advanced Science and Technology (EIAST). It is an optical satellite with a spatial resolution of 0.75 m for the visible and near infrared bands.

Finally, one of the most intriguing launches involves three satellites that form the next part of India’s CartoSat mission. These satellites will carry both high resolution multi- spectral imagers and a panchromatic camera, and the mission’s focus is cartography. It’s not these three satellites that make this launch intriguing, it is the one hundred other satellites that will accompany them!

The Indian Space Research Organisation’s Polar Satellite Launch Vehicle, PSLV-C37, will aim to launch a record 103 satellites in one go. Given that the current record for satellites launched in one go is 37, and that over the last few years we’ve only had around two hundred and twenty satellites launched in an entire year; this will be a hugely significant achievement.

So there you go. Not a fully comprehensive list, as I know there will be others, but hopefully it gives you a flavour of what to expect.

It certainly shows that the EO is not slowing down, and the amount of data available is continuing to grow. This of course gives everyone working in the industry more challenges in terms of storage and processing power – but they are good problems to have. Exciting year ahead!

Will Earth Observation’s power base shift in 2017?

We’re only a few days into 2017, but this year may see the start of a seismic shift in the Earth Observation (EO) power base.

We’ve previously described how the sustainable EO industry really began this week thirty nine years ago. On 6th January 1978 NASA deactivated Landsat-1; it had already launched Landsat-2, carrying the same sensors, three years earlier and with guaranteed data continuity our industry effectively began.

Since then the USA, though the data collected by NASA and NOAA satellites, has led the EO global community. This position was cemented in 2008 when it made all Landsat data held by the United States Geological Survey (USGS) freely available, via the internet, to anyone in the world. This gave scientists three decades worth of data to start investigating how the planet had changed, and companies sprang up offering services based entirely on Landsat data. This model of making data freely available has been so transformational, that the European Union decided to follow it with its Copernicus Programme.

Landsat-1 and 2 were followed by 4, 5, 7 & 8 – sadly Landsat 6 never made its orbit – and Landsat 9 is planned for launch in 2020. The USA’s role EO leadership has never been in question, until now.

US President-elect Donald Trump and his team have already made a number of statements indicating that they intended to cut back on NASA’s Earth Science activities. There are a variety of rumours suggesting reasons for this change of approach. However, irrespective of the reason, slashing the current $2 billion Earth Science budget will have huge consequences. Whilst all of this is just conjecture at the moment, the reality will be seen after 20th January.

Against this America backdrop sits the Copernicus Programme, with the European Space Agency due to launch another three satellites this year:

  • Sentinel 2B is planned for March. This is the second of the twin constellation optical satellites offering a spatial resolution of 10 m for the visible bands. The constellation will revisit the same spot over the equator every five days, with a shorter temporal resolution for higher latitudes.
  • June is the scheduled month for the launch of the Sentinel 5 Precursor EO satellite to measure air quality, ozone, pollution and aerosols in the Earth’s atmosphere. This will be used to reduce the data gaps between Envisat, which ended in 2012, and the launch of Sentinel-5.
  • Sentinel 3B is due to launched in the middle of the year, and like 2B is the second in a twin satellite constellation. This pair is mainly focussed on the oceans and measure sea surface topography, sea and land surface temperature, and ocean and land colour. It will provide global coverage every two days with Sea and Land Surface Temperature Radiometer (SLSTR) and the Ocean and Land Colour Instrument (OLCI).

These launches will take give the Copernicus programme seven satellites collecting a wide variety of optical and radar data across the entire planet, which is then made freely available to anyone. It’s obvious to see what will fill any vacuum created by a reduction in Earth Science in the USA.

Depending on how much of the next US President’s rhetoric is turned into action, we may start to see the shift of the EO power base to Europe. Certainly going to be an interesting year ahead!

Have you read the top Pixalytics blogs of 2016?

As this is the final blog of the year we’d like to take a look back over the past fifty-two weeks and see which blog’s captured people’s attention, and conversely which did not!

It turns out that seven of the ten most widely viewed blogs of the last year weren’t even written in 2016. Four were written in 2015, and three were written in 2014! The other obvious trend is the interest in the number of satellites in space, which can be seen by the titles of six of the ten most widely read blogs:

We’ve also found these blogs quoted by a variety of other web pages, and the occasional report. It’s always interesting to see where we’re quoted!

The other most read blogs of the year were:

Whilst only three of 2016’s blogs made our top ten, this is partly understandable as they have less time to attract the interest of readers and Google. However, looking at most read blogs of 2016 shows an interest in the growth of the Earth Observation market, Brexit, different types of data and Playboy!

We’ve now completed three years of weekly blogs, and the views on our website have grown steadily. This year has seen a significant increase in viewed pages, which is something we’re delighted to see.

We like our blog to be of interest to our colleagues in remote sensing and Earth observation, although we also touch on issues of interest to the wide space, and small business, communities.

At Pixalytics we believe strongly in education and training in both science and remote sensing, together with supporting early career scientists. As such we have a number of students and scientists working with us during the year, and we always like them to write a blog. Something they’re not always keen on at the start! This year we’ve had pieces on:

Writing a blog each week can be hard work, as Wednesday mornings always seem to come around very quickly. However, we think this work adds value to our business and makes a small contribution to explaining the industry in which we work.

Thanks for reading this year, and we hope we can catch your interest again next year.

We’d like to wish everyone a Happy New Year, and a very successful 2017!

Is the UK Space Industry in good health?

Last week the UK Space Agency issued its latest report on the Size and Health of the UK Space Industry, covering 2013/14 and 2014/15. There are a number of eye-catching headlines, but this broad-brush approach means that there are a lot of unanswered questions within the granularity of the report.

UK Space Industry Income is Worth £13.7 bn in 2014/15
This headline figure breaks down into 88% (£12 bn) for downstream activities. Whilst the 12% (£1.7 bn) for upstream activities is much smaller, it is higher than in previous years. Upstream refers to the part of the industry that build and launch satellites and sensors; whilst downstream encompasses the products and services that use the data those objects collect. Overall, the UK represents 6.5% of global space economy.

Unsurprisingly, given the above breakdown, space applications are the biggest segment of the industry, followed by space operations, space manufacturing and ancillary services.

This follows through into capabilities which are dominated by Broadcasting, Communications and Navigation & Timing which account for 56%, 19.6% and 12.2% of the space industry income respectively. Earth observation is listed with an income of £256 m, equating to 1.87% of the overall industry; although Meteorology is shown separately.

38,522 Jobs in the UK Space Industry in 2014/15
The space industry accounts for 0.12% of the total UK workforce, with 29,947 people working in downstream activities, and 8,575 working in upstream. It’s interesting to note the difference in the employment percentages, 78% and 22% respectively, compared to the income split above.

A fascinating fact in the report is that the average qualification level of space industry employees is higher than any other sector in England and Wales. With 74% of employees possessing a degree, 15% holding a HNC and the remaining 11% having other qualifications.

Space Industry Throughout the UK
All regions of the country have space companies. Of course, London and the South East – partially driven by the Harwell Campus – have the highest concentrations. We were delighted to see that the South West had was the third most populous area with 126 space organisations; although the South West is only fourth for Headquarters and income generated with £176 m worth of space business within the area.

UK Space Industry Customers
The report notes that the largest customer type is individual consumers, accounting for 54% of the income. However, given the domination of Broadcasting in the figures and with the majority of their customers being individual consumers this does skew the result. Equally limited information can be gleaned for the other customer types.

Personally, we’d be interested in seeing the customer type split for each capability. This would be much more useful, as at the moment these are a set of high level figures offering little, or no, insight.

Growth Slowing In the Space Industry?
The report has lots of positive statements about growth. There are at least four different income growth rates of 6.5%, 7.3%, 8.1% and 8.5% on page 10, depending on which time period you compare. Similarly, page 12 on employment lists growth rates of 5.8%, 6.0% and 6.7%.

All of this sounds great, but looking at the growth rates within in the tables for the last 7 years, quite wild swings year on year can be seen. The chart below shows some good growth rates, but the last two years are the lowest growth rates.

To be fair the report itself notes a few caveats on the figures, such as new methodologies and the changing value of the pound. So care should be taken with such figures, but does it show signs that growth could be slowing for the industry?

Towards 2030 Ambitions
In February 2010 the UK Government set ambitious targets for the industry of:

  • 8% of the world space economy by 2020, and 10% by 2030.
  • 100,000 jobs created by 2030, taking the industry to 119,100

By the end of 2014/15 progress had been made towards both of these targets, with the industry representing 6.5% of the world space economy and having 38,522 jobs. Employment needs to grow by 7.8% each year to achieve the target, which is concerning given the current growth levels outlined above. If jobs aren’t being created, it’s unlikely the global market share target will be hit.

Shaping The Future
Finally, the UK Space Agency is currently seeking ideas and evidence on how to implement the 2015 National Space Policy. Anyone can submit their thoughts, and we’d encourage everyone to participate in helping shape the future of the UK space industry.

The submission document is straightforward asking for proposed actions, alongside evidence as why they are necessary, for each of the four principles of the National Space Policy

  • Space is of strategic importance to the UK because of the value that space programmes deliver back to public services, national security, science and innovation and the economy.
  • Preserving and promoting the safety and security of the unique space operating environment, free from interference.
  • Supporting the growth of a robust and competitive commercial space sector, underpinned by excellent academic research.
  • Cooperating internationally to create the legal frameworks for the responsible use of space and collaborating with other nations to deliver maximum benefit from UK investment in space.

Conclusion
The UK Space Industry is growing, but we need to ensure that we take advantage of every opportunity and develop, promote and encourage the use of space based applications and technology.

With all the concerns about economic certainty in the coming years, let’s make sure our industry rockets ahead!

Perspectives from the 12th Appleton Space Conference

Last week I attended the 12th Appleton Space Conference, it was the first time I’d been to one of these conferences, and I was excited to be giving a talk. It was hosted by RAL Space at the Harwell Campus.

After the welcome, the day started with a talk from Ross James (Deputy CEO at the UK Space Agency). He’s new to the space community, and so has enjoyed learning to understand it more fully. It was interesting to hear him reinforce the conclusion that the space industry’s value-added multiplier is two, but also that the industry needs to be more regionally and user focused.

Talks then followed by members of European Centre for Space Applications and Telecommunications (ECSAT, the UK’s ESA centre) and the Harwell Campus. I was surprised hear the comparison that the Harwell Campus site is roughly equivalent to the size of the City of London. Whilst Harwell doesn’t yet have any of the iconic tall buildings of the City, it does mean it has plenty of space to grow – with plans to increase the campus to 5 500 jobs by 2020; although it was acknowledged that an upgrade of the underpinning infrastructure would be needed to support this.

After the break we swapped to the topics of growth and innovation. The Autumn Statement had a strong focus on creating an environment for backing winners, with Innovation UK targeted on turning scientific excellence into economic input and scaling up high potential businesses. Two quotes from Tim Just (Innovate UK) that particularly resonated with me:

  • Research is the transformation of money into knowledge; and
  • Innovation transforms it back again.

There was also a debate on whether the space industry is reaching the threshold for a tipping point as outlined in Malcolm Gladwell’s criteria – i.e., where a slow moving trend reaches critical mass and causes a larger change such as the use of space applications and technologies becoming the everyday norm. The last two talks before lunch were on the development of new instruments – including the recently launched Sentinel-3 mission.

The first afternoon session was on understanding scientific advances. We started off by discussing exoplanets (a planet which orbits a star outside the solar system), followed by detecting signals using ground based radars and then understanding gravitational waves. My own talk on harnessing the increasing volumes of Earth Observation (EO) data came at the end of this session. I focused on discussing how there has been a massive change in the amount of available EO data with the need to bring the abilities of computers and humans together to best use this wealth of information.

The slides from my presentation can be found here. It was interesting to see some of the messages people took away from my talk on Twitter such as:

  • The availability of free satellite data is revolutionising remote sensing
  • We have to make the most out of the large quantity of data made available by Earth Observation

After lots of people coming to talk to me during coffee it was great to see Paul Jerram from e2V showing what EO sensors look like, ranging from much larger version of the snapshot imagers found in smart phones to time delay imagers that collect the signal over a period of time so we can have very high resolution imagery. For example, the planet Mars is being imaged at 30 cm resolution. Prof Martin Wooster (Kings College London) focused on biomass burning emissions. Research has shown that the Malaysian fires in 2015, linked to El Nino, contributed to 15% of the global carbon dioxide increases that year but also to thousands of deaths due to the air pollution they caused.

Our day of talks concluded with a keynote lecture by Tim Peake, giving a personal insight into his mission into Space onboard the International Space Station (ISS). As an afternoon speaker I had a front row seat, and so I’m easily spotted on Tim’s room selfie! It was interesting to hear that Tim found adjusting to gravity back on Earth more difficult than weightlessness in space. How much he enjoyed his time on the ISS was obvious when he said he’d be happy to go again as the journey into space was particularly exhilarating.

Whilst aboard the ISS Tim used his limited amount of spare time on Sundays to take photographs of the Earth. Anyone who followed Tim on Twitter will have seen some of these, but he has also now brought out a book of these pictures titled ‘Hello, is this planet Earth? My View from the International Space Station’. An interesting footnote, although not from the conference, is that the UK has just purchased the capsule Tim used to get to, and from, space and it will go on display in the Science Museum next year.

Overall, it was a fantastic day jam packed with interesting, exciting and inspiring discussions about space!

UK Government View On ESA and Space Industry

This week we got a glimpse of the UK Government’s view on the space industry, with the publication of Satellites and Space: Government Response to the House of Commons Science & Technology Committee’s Third Report of Session 2016/17. The original report was published in June and contained a series of recommendations, to which the Government responded.

The timing is interesting for two reasons:

  • Firstly, it comes just before the European Space Agency (ESA) Ministerial Council taking place on Thursday and Friday this week in Lucerne. We highlighted the importance of this meeting in a recent blog.
  • Secondly, it has taken the Government five months to respond, something the Committee themselves were disappointed with.

The Government’s response has a number of insights into the future for the UK space industry. The full report can be seen here, but we wanted to pick out three things that caught our eye:

ESA
For us, and the ESA Ministerial, the most interesting comment was that the Government reaffirmed that the UK will remain a member of ESA after Brexit. It also noted that “The UK’s investment in the European Space Agency is an important part of our overall investment in space, from which we obtain excellent value.” Whilst the level of financial commitment to ESA won’t become clear until the Ministerial, the mood music seems positive.

Earth Observation
The role of the Space for Smarter Government Programme (SSGP) was highlighted, particularly in relation to helping the Department for Environment, Food and Rural Affairs use satellite data more. As part of SSGP we ran a successful Flood Mapping project during 2015/16. SSGP is running again this year, but given the importance placed on the programme on embedding space activities within Government it was disappointing not to see a further commitment beyond March 2017.

A business plan for a Government Earth Observation Service is currently being written, which is aimed at increasing the uptake of EO data within Government. We’ve not seen too much about this service yet, and will be very interested in the business plan.

Responding a question on harnessing the public interest in Tim Peake’s time in space, it was nice to see the work of the EO Detective highlighted. This is a fantastic project that raises awareness of the space industry in schools, and uses space/satellite imagery to help children explore topics such as climate change.

Small Satellites
“The Government intends to establish the UK as the European hub for low cost launch of small satellites.” It’s an interesting ambition; although it’s not completely clear what they mean by the term small satellites. As we described last week definitions are important.

On top of the three points above there were some words on funding for space related research; however these amounted to no more than an acknowledgement that various Government bodies will work together. There was also reference to the development of a new Space Growth Strategy, something we’ll talk more about in two weeks.

The Government’s response to this report was an interesting read, and whilst there are still a lot of unanswered questions it does hint at cautious optimism that they will support the space industry.

We were all on tenterhooks this week waiting the big announcements from the ESA Ministerial, and here are some of the headline outcomes:

  • Overall, ESA’s 22 member states plus Slovenia and Canada allocated €10.3 billion for space activities and programmes over the next five years. This includes an EO programme valued at €1.37 bn up until 2025.

Within this overall envelope, the UK has allocated €1.4 bn funding over five years, which equates to 13.5% of total. This includes:

  • €670.5 m for satellite technology including telecommunications, navigation and EO.
  • €376.4 m for science and space research
  • €82,4 m for the ExoMars programme.
  • €71 m for the International Space Station Programme
  • €22 m for innovate space weather missions

Our eye was, of course, drawn to the investment in EO and there is a little more detail, with the €670.5 m is:€60 m for the development of the commercial use of space data €228.8 m for environmental science applications and climate services through ESA’s EO programme, including:

  • Incubed – a new programme to help industry develop the Earth observation satellite technology for commercial markets
  • the Biomass mission to measure the carbon stored in the world’s forests
  • the Aeolus mission, measuring wind speed in three dimensions from space

Finally, it is worth noting Katherine Courtney, Chief Executive of the UK Space Agency, who commented, “This significant investment shows how the UK continues to build on the capability of the UK space sector and demonstrates our continuing strong commitment to our membership in the European Space Agency.”
