Astrobiology Magazine -- MARSIS, the Mars Advanced Radar for Subsurface and Ionosphere Sounding onboard ESA's Mars Express orbiter, is now fully deployed, has undergone its first checkout and is ready to start operations around the Red Planet. With this radar, the Mars Express orbiter at last has its full complement of instruments available to probe the planet's atmosphere, surface and subsurface structure. MARSIS consists of three antennas: two 'dipole' booms 20 metres long, and one 7-metre...

ESA -- The second 20-metre antenna boom of the MARSIS instrument on board Mars Express was successfully "“ and smoothly "“ deployed, confirmed today by the ground team at ESA's European Space Operations Centre. The command to deploy the second MARSIS boom was given to the spacecraft at 13:30 CEST on 13 June 2005. Shortly before the deployment started, Mars Express was set into a slow rotation to last 30 minutes during and after the boom extension. This rotation allowed all the...

ESA -- Drilling holes on other planets and inventing novel textiles to secure large structures in space are just two of the 27 challenges that expert teams have been working on in the first year of ESA's Innovation Triangle Initiative. "By combining the creativity of the inventor, the needs of end users and the production experience of industry we have created strong drive and a very successful synergy to identify, demonstrate and verify novel ideas for future space technologies," says...

ESA -- These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show Coprates Chasma, a major trough in the Valles Marineris canyon system. The HRSC obtained these images during orbit 449 with a ground resolution of approximately 48 metres per pixel. The scenes show the region containing the sections of Coprates Chasma and Coprates Catena, over an area centred at about 13.5º South and 300º East, roughly in...

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...
