UCL space missions get the go-ahead

University College London space scientists are involved in two out of four missions that have been selected by the European Space Agency to compete for a launch opportunity at the start of the 2020s.

EChO - the Exoplanet Characterisation Observatory - will search for signs of life on planets which are orbiting stars nearby our sun. Led by Dr. Giovanna Tinetti, UCL Physics and Astronomy, and supported by over 150 of Europe's astronomers, the mission conisists of a 1.2 metre telescope designed to carry out spectroscopy of the atmospheres of a range of extra solar planets, from giant gas planets (similar to Jupiter in our own Solar System) down to in the of some stars.

"This is tremendously exciting news," said Dr. Tinetti. "One of the key aims of our mission is to see if we can detect molecules such as ozone and carbon dioxide in the atmospheres of planets not much bigger than our Earth. These molecules are key biomarkers - signs that life might be, or might have been, present."

Dr. Tinetti has a strong record in exoplanet research. She led the team that made the first discovery of water in an atmosphere, opening up a new era in understanding these alien worlds. EChO will try to and understand the and thermal structure of these planets, through which scientists hope to unveil their physical processes, formation and evolution.

The second mission, LOFT - the Large Observatory For Timing - will study the fast-moving, high-energy environments that surround , and pulsars - objects that can produce sudden and very rapid bursts of X-rays. The UCL Mullard Space Science Laboratory has a strong involvement in the science team (Dr. Silvia Zane and Dr. Roberto Mignani) as well as the engineering team of the mission.

LOFT will carry two instruments, the Large Area Detector (LAD) and the Wide Field Monitor (WFM), to be operated in parallel and search for fast X-ray variability. The MSSL engineering group will be key in developing the design of of the on-board electronics, including the payload data handling units, the instrument control units, the flight digital electronics and the power supply units on board the spacecraft. Other contributions of MSSL include technical support in the spacecraft design and in the construction of the micro-channel plate detectors of the Large Area Detector (LAD), the main instrument aboard LOFT.

"This mission has terrific potential," said Dr. Zane. "We are really looking forward to the possibility of flying an X-ray instrument capable of performing such high time resolution observations. This is a very ambitious goal that will open a new window on our understanding of the strongest gravitational fields in the Universe."

Both spacecraft were sected from nearly 50 mission proposals made to the . "We had to overcome really tough competition to get selected for further study and possible launch," said Dr. Tinetti.
