Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits on the Moon near its north pole.

This is exciting news the World over because water is a key factor in the ability of an extra terrestrial environment to support life. The SSTL team is also watching with great interest because the payload is controlled by a specially built on-board computer (OBC) built by its team in Guildford - its first to be flown onboard a lunar mission. The OBC is programmed to control the instrument and to store the payload data which is then beamed back to the astounded NASA scientists on Earth.

NASA's Mini-SAR instrument found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to 15 km) in diameter. Although the total amount of ice depends on its thickness in each crater, it's estimated there could be at least 1.3 trillion pounds (600 million metric tons) of water ice.

SSTL has been selected by the European Space Agency (ESA) to manage a pan-European student built mission to the Moon. The European Student Moon Orbiter (ESMO) programme will place a spacecraft into a lunar orbit to map the lunar surface, acquiring images and other scientific data about our nearest neighbour.

Students from at least 10 universities throughout ESA's Member States and Cooperating States will learn about space science and engineering “hands on” by collaborating on the design and building of systems that could be launched into orbit around the Moon as soon as 2013.

SSTL will draw upon its experience in delivering cost effective space missions and training schemes to project manage the European Student Moon Orbiter (ESMO) mission, supervising the academic and student teams throughout Europe to help them achieve their goal of a space-ready Moon orbiter.

Professor Sir Martin Sweeting, Executive Chairman of SSTL said, “SSTL has had its sights on the Moon for nearly a decade and ESMO combines the industrial and educational strengths of SSTL towards this exciting challenge. We have shown many times in the past that success in space can be achieved at a fraction of the cost normally considered and we expect that this exciting mission will further demonstrate that this applies as well to science missions as Earth Observation and communications.”

SSTL Lunar Expert Andy Phipps commented, “ESMO is an extremely exciting opportunity for these European students to learn about space “hands-on”, but with the practical insight and support of our training and development programmes.

“Having successfully delivered the radar payload processor to BAE Systems for NASA’s contribution to the Indian lunar mission Chandrayaan-1, the ESMO project is just as significant for SSTL and forms the next step on our lunar roadmap – the delivery of a complete mission”, continued Phipps.

SSTL was recently down-selected by the UK government’s STFC (Science and Technology Facilities Council) to lead the design phase for the MoonLITE mission, which will lead to the development and launch of a low-cost lunar orbiter carrying scientific lunar surface penetrators and a communications relay payload to the Moon in 2014.

Minister for Science and Innovation, Ian Pearson today visited SSTL’s headquarters in Guildford to discuss the company’s important contribution to the UK space industry. His visit follows the release of the UK Civil Space Strategy on February 14th, which outlines the Government's future direction for the sector for 2008-2012.

Mr Pearson visited SSTL operations critical to supporting the Government’s space objectives. This included an introduction to SSTL’s DMCii Ltd subsidiary, where he met the team that are currently leading the International Charter: Space and major disasters on behalf of the BNSC. He also met project managers from the European Space Agency (ESA) missions such as the highly successful Galileo satellite, GIOVE-A, and discussed the role of small satellites in providing security and military capabilities.

Speaking at SSTL, Minister for Science and Innovation, Ian Pearson, said:

"The UK Civil Space Strategy outlined the Government's commitment to the UK space industry and measures to ensure UK businesses increase their share of the growing international sector. As I've seen today some of the most innovative work in this area is being carried out right here in Surrey."

The highlight of Mr Pearson’s visit was the presentation of plans that will secure the UK’s closer involvement in international initiatives on the future shape of space exploration to the Moon, Mars and beyond. SSTL will take the lead on landmark missions to prove new technologies that will provide low cost infrastructure for future lunar missions. These could include the provision of communications from the Moon back to Earth. This British-supplied infrastructure could also be used to relay communications back from interplanetary missions, for example Mars to Earth.

Sir Martin Sweeting, SSTL Group Executive Chairman, commented,

“SSTL is pioneering innovative low cost technologies that maintain and develop the UK’s market share in the global space sector. In particular, SSTL’s MoonLite and MoonRaker missions with NASA are of great importance to the British government’s space strategy going forward.”

In time, a constellation of satellites could also be built up to provide valuable services such as GPS in the same way as the Earth. This satellite infrastructure will provide essential services to the international missions on the Moon’s surface such as Rovers, Landers and smaller space experiments that are planned by nations such as Russia, China, India and the US over the coming years.

Back in August, the Sky at Night invited Martin Sweeting down to Patrick Moore's home in Sussex to film an interview for a programme celebrating 50 years of space. This program will also include a discussion of SSTL's lunar studies with Andy Phipps.

The Sky at Night
Dr Chris Lintott finds out how British technology is leading the way in satellite science, while Sir Patrick Moore investigates the threat from space debris that astronauts face in space.

For anyone that would like to tune in, the Sky at Night will be broadcast this Sunday evening, 2nd December, on BBC 4 at 20:30.
