Artists impression of Boom 2 deployed
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 14 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 boom’s hinges to be properly heated by the Sun.
Just after, an autonomous manoeuvre oriented the spacecraft towards the Sun, to have the spacecraft recharge its batteries and for a further heating of the hinges.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
