Europe's New Mars Orbiter Begins Testing Science Gear

The Trace Gas Orbiter (TGO) arrived at Mars on Oct. 19 and is currently circling the planet once every 4.2 days. TGO was scheduled to begin testing and calibrating its four instrument suites on Sunday (Nov. 20), and this work should continue through next Monday (Nov. 28), European Space Agency (ESA) officials said late last week. "We’re excited we will finally see the instruments perform in the environment for which they were designed, and to see the first data coming back from Mars," Håkan Svedhem, ESA’s TGO project scientist, said in a statement on Friday (Nov. 18).
