Latest MARSIS Stories
Following in-depth analyses performed after the deployment of the first MARSIS antenna boom on board Mars Express, ESA has decided to proceed with the deployment of the second 20-metre antenna boom.
Thanks to a manoeuvre performed on 10 May 2005 at 20:20 CET, ESA flight controllers have successfully completed the deployment of the first boom of the MARSIS radar on board ESA's Mars Express spacecraft.
The deployment of the second antenna boom of the Mars Express Sub-Surface Sounding Radar Altimeter (MARSIS) science experiment has been delayed pending investigation of an anomaly found during deployment of the first antenna boom.
During the next couple of weeks, if all goes as planned, the martial arts champion of radar antennas will kickbox its way into space. Weighing in at a mere 4 pounds (1.8 kilograms) and packing a pyrotechnic punch, the MARSIS antenna will spring into operation in May.
Following green light for the deployment of ESAâ€™s Mars Express radar, given in February this year, the radar booms are now planned to be deployed in the first half of May.
After a year's delay, the MARSIS instrument on the European Space Agency's Mars Express orbiter will soon be deployed. In this interview, Jeffrey Plaut of the Jet Propulsion Laboratory describes how the radar instrument could uncover how much, if any, liquid water lies hidden below the surface of Mars.
The use of orbiting radar to probe the first three miles underneath the martian surface has been greenlighted. Following review board panels to assess the feasibility, the Mars Express probe will commence its underground searching in May.
The European Space Agency has given the green light for the MARSIS radar on board its Mars Express spacecraft to be deployed during the first week of May. Assuming that this operation is successful, the radar will finally start the search for subsurface water reservoirs and studies of the Martian ionosphere.
