Europe’s Trace Gas Orbiter sends its first color picture of Mars – and it’s spectacular

The first color picture to return from a digicam aboard the ExoMars Trace Gas Orbiter in its Mars-mapping orbit reveals the ice-coated rim of Korolev Crater in sharply shadowed element.

“We had been actually happy to see how good this picture was, given the lighting circumstances,” Antoine Pommerol, a member of the science group for the Color and Stereo Floor Imaging System, said today in a news release. “It reveals that CaSSIS could make a serious contribution to research of the carbon dioxide and water cycles on Mars.”

The ExoMars Trace Gas Orbiter, a mission collectively supported by the European and Russian house companies, is constructed to measure the composition of Mars’ skinny ambiance with unprecedented accuracy. Its high activity is to search for methane and different hint gases that might trace at organic or geological exercise.

The car-sized probe was launched in 2016, and after a sequence of aerobraking maneuvers, it reached its final 250-mile-high orbit around Mars this month. Its spectrometers started “sniffing” atmospheric molecules simply final weekend.

CaSSIS has been going via a take a look at section for greater than a month, in preparation for a major science mission that’s on account of start on Saturday. (The digicam despatched again images of Mars and a color view of the Martian moon Phobos throughout earlier orbital checks going again to 2016.)

“We have now had a pair of minor software program points within the preliminary take a look at section,” the digicam’s principal investigator, Nicolas Thomas of the College of Bern in Switzerland, said in a news release. “However the instrument is definitely in good well being and able to work.”

Three CaSSIS photographs in numerous wavelengths had been captured on April 15 and mixed to supply the picture of Korolev Crater, named after pioneering Soviet rocket engineer Sergei Korolev.

CaSSIS and the sniffing spectrometers are half of an array of scientific instruments that can observe seasonal adjustments within the ambiance’s composition and temperature, and hyperlink these adjustments to options on the Martian floor. For instance, CaSSIS might conceivably spot volcanoes or ice deposits which can be related to hint methane emissions.

“Our intention is to completely automate the picture manufacturing course of,” Thomas mentioned. “As soon as we obtain this, we will distribute the information to the neighborhood shortly for evaluation.”

The Trace Gas Orbiter is an element of a European-led scientific marketing campaign that additionally features a Mars rover and a floor science platform, due for launch in 2020. Along with its scientific duties, the orbiter will function a communications relay satellite tv for pc for these robotic probes.

That relay functionality was efficiently examined this week with NASA’s Curiosity rover, ESA mentioned.
