The Laser Interferometer Space Antenna (LISA) consists of three spacecraft orbiting the sun in a triangular configuration. The LISA mission will study the mergers of supermassive black holes, test Einstein's theory of general relativity, probe the early universe, and search for gravitational waves. As these passing waves ripple space and time, they will alter the laser beams shining between the spacecraft, offering a different perspective on the Universe. LISA is scheduled for launch in 2015.

View of the LISA Pathfinder space probe being launched onboard its Vega rocket on 3rd December 2015. The LISA (Laser Interferometer Space Antenna) Pathfinder was a joint NASA and European Space Agency (ESA) programme. It was designed to test the fundamental technologies and instrumentation needed for future gravitational-wave observatories in space. LISA Pathfinder carries two advanced instruments, the LTP (LISA Technology Package) and Disturbance Reduction System (DRS). The LTP is designed to simulate the observational arrangement for the LISA mission. The DRS is an experiment provided by NASA's Jet Propulsion Laboratory in California, which includes also a set of micro-rockets that aim to control the spacecraft's position to within a millionth of a millimetre. Filmed at Guiana Space Centre (Centre Spatial Guyanais), Kourou, French Guyana, on 3rd December 2015.

Physicist Lisa Baddeley observing solar activity at her lab at the Kjell Henriksen Observatory, Svalbard, Norway. Baddeley is an Associate Professor in space physics at the University Centre in Svalbard. She studies the interaction of solar wind on the Earth's magnetic field, a phenomenon that is observed at high latitudes as the aurora. Solar storms can affect modern telecommunication systems such as satellites, TV signals, telephones, GPS navigation and power systems. Photographed in 2014.
