ESA -- 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. The full operation will be performed during a time frame starting 13 June and nominally ending on 21 June. A delay in the execution of the second boom deployment was necessary, due to problems encountered with the first deployment in early May this year. During the deployment, one of...

ESA -- 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. After the start of the deployment of the first 20-metre boom on 4 May, analysis by flight controllers at ESA's European Space Operations Centre, Darmstadt, Germany, had shown that although 12 out of the 13 boom segments were in place, one of the outermost segments, possibly No. 10,...

ESA -- 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. The anomaly was discovered on 7 May towards the end of the first deployment operations. Deployment of the first boom started on Wednesday 4 May. The problem with the boom was confirmed by flight control engineers working at ESA's European Space...

NASA -- 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, which stands for Mars Advanced Radar for Subsurface and Ionospheric Sounding, will spring into operation in May. On each of its two main "arms," thirteen segments will quickly uncoil, taking a few seconds to reach their full length of 20 meters (65 feet)...

ESA -- Following green light for the deployment of ESA's Mars Express radar, given in February this year, the radar booms are now planned to be deployed in the first half of May. Once the deployment is successful, the Mars Express MARSIS radar will enable the first European spacecraft to orbit Mars to complement its study of the planet's atmosphere and surface. MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument) is the first antenna of its kind which was also...

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. Astrobiology Magazine -- The first week of May, the Mars Express spacecraft will unfurl its radar antenna. The Mars Advanced Radar for Subsurface and Ionosphere Sounding - or MARSIS - will have...

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. Astrobiology Magazine -- 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...

ESA -- 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. ESA's decision to deploy MARSIS follows eight months of intensive computer simulations and technical investigations on both sides of the Atlantic. These were to assess...
