We are ready now to ship the spacecraft to Baikonur and launch it.\u201d<\/p>\n<p>The launch scheduled for March 14 aboard a Russian Proton rocket is the first of Europe\u2019s two-part ExoMars program, ESA\u2019s most ambitious Mars mission to date. Next year\u2019s launch will be followed up in May 2018 by the liftoff of a European-built rover that will descend to the Martian surface.<\/p>\n<p>The road to the launch pad appears for the 2016 launch appears smooth, assuming no last-minute glitches, according to Walter Cugno, ExoMars program director at Thales.<\/p>\n<p>\u201cWe want to be ready for the first launch attempt, which is March 14,\u201d Cugno told Spaceflight Now in an interview. \u201cThe launch window is up to the 25th of March, but we want to be ready for the first attempt to have some margin just in case.\u201d<\/p>\n<p>Cugno said ground crews have worked in three shifts \u2014 around the clock \u2014 more more than a year to make sure the two spacecraft are ready to meet their launch date.<\/p>\n<p>The long days are not over.<\/p>\n<p>A final vibration and acoustic test of the spacecraft, along with communications link checks with Europe\u2019s spaceflight control center in Germany, are the last items on the to-do list before the orbiter and lander are packed up and flown to Kazakhstan.<\/p>\n<p>In the video below, Cugno gives a brief tour of ExoMars Trace Gas Orbiter and attached Schiaparelli lander during a press visit Nov. 25.<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/player.vimeo.com\/video\/146966785\" width=\"620\" height=\"349\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>Three Antonov cargo jets will depart an airport in Torino, Italy, on Dec. 18, 19 and 21. The flights will go through Moscow for a customs check, then proceed to Baikonur.<\/p>\n<p>The first flight of the heavy-duty transport plane will deliver ground support equipment, including a tent in which the Mars lander will be prepared for launch. The tent is necessary to meet stringent contamination restrictions crafted to prevent Earth bacteria from reaching Mars, and no clean room exists at Baikonur pristine enough to meet the requirements, Cugno said.<\/p>\n<p>The second and third Antonov transports will take the lander and orbiter to the Kazakh launch base on separate sorties.<\/p>\n<p>Teams have just one day of schedule margin, excluding weekends, to have the entry module ready in time for March 14. The schedule for the orbiter is less tight, Cugno said.<\/p>\n<p>Technicians will work nonstop over the holidays to try to build up more breathing room in the schedule. If the launch is not off by March 25, or perhaps a couple of days later, the mission will be delayed more than two years because the planets are out of alignment to make the voyage possible.<\/p>\n<p>\u201cWe arrive in Baikonur a few days before Christmas, and we are going to work through Christmas continuously without any break until we will be finalizing the checkouts in preparation for the launch,\u201d Cugno said.<\/p>\n<p>Propellants for the lander\u2019s descent rockets will be loaded at the end of January, and workers will attach the descent capsule to the orbiter Feb. 12, according to Cugno. Then the orbiter will be ready to receive its propellants, totaling 2.3 metric tons (5,070 pounds), comprising more than half its liftoff weight.<\/p>\n<p>The procedure to attach the spacecraft to the Proton launcher and its Breeze M upper stage begins Feb. 26.<\/p>\n<p>Cramped work timelines are nothing new for the ExoMars program, which still faces a schedule and budget crunch to have the rover and its carrier ready in time for its May 2018 launch window.<\/p>\n<p>Delays and the sudden withdrawal of NASA\u2019s partnership have shaped the ExoMars program, which started as part of ESA\u2019s Aurora exploration initiative in 2001.<\/p>\n<p>NASA announced in 2012 the U.S. government could not afford a plan to supply a \u201csky crane\u201d descent system \u2014 a vehicle similar to the landing module that carried the Curiosity rover to the Martian surface \u2014 for the ExoMars rover mission. The U.S. space agency also said it would not provide an Atlas launcher the 2016 and 2018 missions, and it canceled a plan to build a U.S. rover to go with the European 2018 launch, which would have landed two rovers on Mars in one go.<\/p>\n<p>In the wake of NASA\u2019s departure from the program, ESA turned to Russia to launch the missions and develop the 2018 rover\u2019s atmospheric entry system.<\/p>\n<figure id=\"attachment_10878\" aria-describedby=\"caption-attachment-10878\" style=\"width: 621px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-10878\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2015\/12\/EDM_module_being_installed_at_the_top_of_the_TGO_node_full_image_2.jpg\" alt=\"Technicians attach the ExoMars 2016 mission's Schiaparelli landing probe to the Trace Gas Orbiter ahead of a final set of ground tests at the Thales Alenia Space factory in Cannes, France.

Without the transducers, ground controllers give up some insight into the performance of the entry probe, but the propulsion system can still function normally, officials said.<\/p>\n<p>ESA and Thales Alenia Space briefed reporters on the status of the ExoMars missions in Cannes on Nov. 25, showcasing the 2016 spacecraft in launch configuration, with the orbiter fully assembled crowned by the landing module.<\/p>\n<p>The landing craft is named for Italian astronomer Giovanni Schiaparelli, who observed Mars in the 19th century through telescopes and created the first maps of the red planet.<\/p>\n<p>Schiaparelli marked natural channels coursing across Mars, and his maps inspired a wave of interest in the red planet, leading to the construction of new telescopes to further study the rust-colored world.<\/p>\n<p>The orbiting component of the 2016 mission, called the Trace Gas Orbiter, hosts science instruments from across Europe and Russia.<\/p>\n<p>Two sensor packages will measure the constituents of the Martian atmosphere with greater spectral resolution than ever before, teasing out the tiniest concentrations of molecules.<\/p>\n<p>A key objective of the Trace Gas Orbiter will be to look for methane, a gas that has been intermittently detected in the planet\u2019s atmosphere by Europe\u2019s Mars Express orbiter, ground-based observatories and NASA\u2019s Curiosity rover.<\/p>\n<p>But the methane levels are extremely low, bordering on signal noise in the data streams from Curiosity, with apparent occasional unexplained spikes.<\/p>\n<p>Jorge Vago, ESA\u2019s ExoMars project scientist, said the methane could come from two possible sources.<\/p>\n<p>\u201cOne would be metabolizing active bacteria, maybe in the subsurface,\u201d Vago told reporters Nov. 25. \u201cThe other one could be some processes that also happen on Earth in which certain minerals in the mantle react with water at relatively low temperatures, for geology, at 200 to 300 degrees (Celsius), releasing hydrogen which then could combine with carbon dioxide to form methane.\u201d<\/p>\n<p>While the prospect that the methane could come from burps from microbes is tantalizing, scientists say either explanation would be enlightening.<\/p>\n<figure id=\"attachment_10879\" aria-describedby=\"caption-attachment-10879\" style=\"width: 623px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-10879\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2015\/12\/PIA16461_ip.jpg\" alt=\"NASA created this infographic illustrating the possible sources and sinks of methane on Mars.

Earth, which is larger than Mars and still able to support churning super-heated rock deep underground, will reach a similar fate in the distant future, but still well before the sun goes dark.<\/p>\n<p>Volcanic activity on Mars ended less than 100 million years ago, perhaps as little as a few million years ago, Bibring said.<\/p>\n<p>\u201cBut it might be the outgassing has not finished, and that most of what we see now in the atmosphere of Mars, the few millibars of what we have including the trace gases, are the result of the still active processes deep inside Mars,\u201d said Bibring, who is also the chief scientist on Europe\u2019s Philae comet lander.<\/p>\n<p>\u201cHow does that happen? Mars will tell us that because Mars is at that point where volcanism has probably died, but not the outgassing, and that\u2019s really the beauty of TGO (Trace Gas Orbiter),\u201d Bibring said in Cannes. \u201cIt will monitor this phase while it\u2019s still happening on Mars now, probably venting all sorts of things, such as methane. It\u2019s not just the question of the biology, it\u2019s much more than that.\u201d<\/p>\n<p>The orbiter also carries a camera to map the Martian surface, and a Russian-made neutron detector tailored to find deposits of water or minerals like clays, which formed in water on ancient Mars.<\/p>\n<p>The Schiaparelli lander, developed with Italian leadership, would become the first European craft to safely touch down on Mars.<\/p>\n<figure id=\"attachment_10880\" aria-describedby=\"caption-attachment-10880\" style=\"width: 621px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-10880\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2015\/12\/Schiaparelli_interior_node_full_image_2.jpg\" alt=\"Diagram of the Schiaparelli lander.

Three days before the spacecraft arrives at Mars, on Oct. 16, the orbiter will release the descent probe for its plunge to the Martian surface.<\/p>\n<p>It is heading for a flat plain named Meridiani Planum, targeting a landing point near the location of NASA\u2019s Opportunity rover.<\/p>\n<p>Schiaparelli\u2019s six-minute descent on Oct. 19, aided by a supersonic parachute and braking rockets, will culminate with a crash landing of sorts. The thrusters will cut off when the probe\u2019s landing radar detects it is less than 2 meters, or 6.6 feet, above the ground.<\/p>\n<p>A \u201ccrushable\u201d carbon-fiber structure, made in Spain, will protect the lander when it hits the surface.<\/p>\n<p>Schiaparelli has its own suite of science instruments, primarily designed to monitor the Martian atmosphere during descent and to serve as a meteorological station on Mars during the battery-powered lander\u2019s short life, which is expected to last between two and eight days.<\/p>\n<p>The craft\u2019s arrival in October will be during the Martian dust storm season, making Schiaparelli the first Mars lander to touch down under such conditions. Scientists hope to get a vertical profile of the atmosphere on the probe\u2019s descent for the first time during the dust storm season.<\/p>\n<p>Europe\u2019s last mission to Mars in 2003 launched the Mars Express orbiter, which is still returning science from the red planet well beyond its two-year lifetime, and the Beagle 2 landing module built in Britain.<\/p>\n<p>Ground controllers never heard from Beagle 2 after its landing attempt, but scientists early this year revealed new imagery from NASA\u2019s sharp-eyed Mars Reconnaissance Orbiter apparently showing the spacecraft intact on the red planet, but with its solar arrays still partially folded.<\/p>\n<p>The discovery led engineers to conclude Beagle 2 may have survived its landing, but a problem prevented full deployment of the solar panels, potentially blocking the antenna that was to radio its status to Earth.<\/p>\n<p>Schiaparelli\u2019s flight to Mars is Europe\u2019s second try, with a much bigger package than Beagle 2. It goes to Mars with a doppler radar guidance system, modernized control algorithms and a computer that will be crucial to the 2018 mission\u2019s rover landing.<\/p>\n<p>It also boosts Europe\u2019s bonafides when it comes to future Mars projects, such as an audacious concept to return samples to Earth.<\/p>\n<p>\u201cIf you want to be a partner in the future in more missions to Mars, if you don\u2019t demonstrate your capability to land, you are not at the right level,\u201d Gimenez said. \u201cWe have to demonstrate we can do it ourselves, and that\u2019s what we will do with this mission.\u201d<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Artist\u2019s concept of Europe\u2019s ExoMars Trace Gas Orbiter at Mars.
