ExoMars 2018 Rover Postponed to 2020 Launch

Liftoff of the ExoMars 2018 rover mission currently under development jointly by Europe and Russia has just been postponed for two years to 2020, according to an announcement today, May 2, from the European Space Agency (ESA) and the Russian space agency Roscosmos.

The delay was forced by a variety of technical and funding issues that ate up the schedule margin to enable a successful outcome.

“Taking into account the delays in European and Russian industrial activities and deliveries of the scientific payload, a launch in 2020 would be the best solution,” ESA explained in a statement today.

The ambitious ExoMars rover is the second of two joint Euro-Russian missions to explore the Red Planet.

The first mission known as ExoMars 2016 was successfully launched last month from the Baikonur Cosmodrome in Kazakhstan atop a Russian Proton-M rocket on March 14.

The renamed ExoMars 2020 mission involves a European-led rover and a Russian-led surface platform and is also slated to blastoff on an Russian Proton rocket.

Roscosmos and ESA jointly decided to move the launch to the next available Mars launch window in July 2020. The costs associated with the delay are not known.

The delay means that the Euro-Russian rover mission will launch the same year as NASA’s 2020 rover.

The rover is being built by prime contractor Airbus Defense and Space in Stevenage, England.

The descent module and surface science package are provided by Roscosmos with some contributions by ESA.

Recognizing the potential for a delay, ESA and Roscosmos set up a tiger team in late 2015 to assess the best options.

“Russian and European experts made their best efforts to meet the 2018 launch schedule for the mission, and in late 2015, a dedicated ESA-Roscosmos Tiger Team, also including Russian and European industries, initiated an analysis of all possible solutions to recover schedule delays and accommodate schedule contingencies,” said ESA in the statement.

The tiger team reported their results to ESA Director General Johann-Dietrich Woerner and Roscosmos Director General Igor Komarov.

Woerner and Komarov then “jointly decided to move the launch to the next available Mars launch window in July 2020, and tasked their project teams to develop, in cooperation with the industrial contactors, a new baseline schedule aiming towards a 2020 launch. Additional measures will also be taken to maintain close control over the activities on both sides up to launch.”

The ExoMars 2016 interplanetary mission is comprised of the Trace Gas Orbiter (TGO) and the Schiaparelli lander. The spacecraft are due to arrive at Mars in October 2016.

The goal of TGO is to search for possible signatures of life in the form of trace amounts of atmospheric methane on the Red Planet.

The main purpose of Schiaparelli is to demonstrate key entry, descent, and landing technologies for the follow on 2nd ExoMars mission that will land the first European rover on the Red Planet.

The now planned 2020 ExoMars mission will deliver an advanced rover to the Red Planet’s surface. It is equipped with the first ever deep driller that can collect samples to depths of 2 meters (seven feet) where the environment is shielded from the harsh conditions on the surface – namely the constant bombardment of cosmic radiation and the presence of strong oxidants like perchlorates that can destroy organic molecules.

ExoMars was originally a joint NASA/ESA project.

But thanks to hefty cuts to NASA’s budget by Washington DC politicians, NASA was forced to terminate the agencies involvement after several years of extremely detailed work and withdraw from participation as a full partner in the exciting ExoMars missions.

NASA is still providing the critical MOMA science instrument that will search for organic molecules.

Thereafter Russia agreed to take NASA’s place and provide the much needed funding and rockets for the pair of launches in March 2016 and May 2018.

TGO will also help search for safe landing sites for the ExoMars 2020 lander and serve as the all important data communication relay station sending signals and science from the rover and surface science platform back to Earth.

ExoMars 2016 is Europe’s most advanced mission to Mars and joins Europe’s still operating Mars Express Orbiter (MEX), which arrived back in 2004, as well as a fleet of NASA and Indian probes.

The Trace Gas Orbiter (TGO) and Schiaparelli lander arrive at Mars on October 19, 2016.

ExoMars Spacecraft Launches to Red Planet Searching for Signs of Life

The joint European/Russian ExoMars spacecraft successfully launched early this morning from the Baikonur Cosmodrome in Kazakhstan atop a Proton-M rocket at 5:31:42 a.m. EDT (0931:42 GMT), Monday, March 14, with the goal of searching for signs of life on the Red Planet.

The spacecraft is currently circling in a temporary and preliminary parking orbit around Earth following liftoff of the 191-foot-tall (58-meter) Russian-built rocket under overcast skies – awaiting a critical final engine burn placing the probe on an interplanetary trajectory to Mars.

The 9,550-pound (4,332-kilogram) ExoMars 2016 spacecraft continued soaring to orbit after nominal firings of the Proton’s second and third stages and jettisoning of the payload fairing halves protecting the vehicle during ascent through Earth’s atmosphere.

A total of four more burns from the Breeze-M upper stage are required to boost ExoMars higher and propel it outwards on its seven-month-long journey to the Red Planet.

So the excitement and nail biting is not over yet and continues to this moment. The final successful outcome of today’s mission cannot be declared until more than 10 hours after liftoff – after the last firing of the Breeze-M upper stage sets the probe on course for Mars and escaping the tug of Earth’s gravity.

The first three Breeze-M fourth stage burns have now been completed as of about 9:40 am EST, according to ESA mission control on Darmstadt, Germany.

The fourth and final ignition of the Breeze-M upper stage and spacecraft separation is slated for after 3 p.m. EDT today, March 14, 2016.

The first acquisition of signal from the spacecraft is expected later at about 5:21:29 p.m. EST (21:29 GMT).

The ExoMars 2016 mission is comprised of a joined pair of European-built spacecraft consisting of the Trace Gas Orbiter (TGO) plus the Schiaparelli entry, descent and landing demonstrator module, built and funded by the European Space Agency (ESA).

The cooperative mission includes significant participation from the Russian space agency Roscosmos who provided the Proton-M launcher, part of the science instrument package, the surface platform and ground station support.

ESA is continuing live streaming of the launch events throughout the day as burns continue and events unfold lead up to the critical final burn of the Breeze-M upper stage

The ExoMars 2016 TGO orbiter is equipped with a payload of four science instruments supplied by European and Russian scientists. It will investigate the source and precisely measure the quantity of the methane and other trace gases.

The 2016 lander will carry an international suite of science instruments and test European entry, descent and landing (EDL) technologies for the 2nd ExoMars mission in 2018.

The battery powered lander is expected to operate for perhaps four and up to eight days until the battery is depleted.

The 2018 ExoMars mission will deliver an advanced rover to the Red Planet’s surface.

It is equipped with the first ever deep driller that can collect samples to depths of 2 meters (seven feet) where the environment is shielded from the harsh conditions on the surface – namely the constant bombardment of cosmic radiation and the presence of strong oxidants like perchlorates that can destroy organic molecules.

The countdown has begun for blastoff of the ambitious European/Russian ExoMars 2016 spacecraft from the Baikonur Cosmodrome in Kazakhstan on March 14. Its goal is to search for minute signatures of methane gas that could possibly be an indication of life or of nonbiologic geologic processes ongoing today.

Final launch preparations are now in progress. Liftoff of the powerful Russian Proton booster from Baikonur carrying the ExoMars spacecraft is slated for 5:31:42 a.m. EDT (0931:42 GMT), Monday morning, March 14.

You can watch the launch live courtesy of a European Space Agency (ESA) webcast:

http://www.esa.int/Our_Activities/Space_Science/ExoMars/Watch_ExoMars_launch

The prelaunch play by play begins with live streaming at 4:30 a.m. EDT (08:30 GMT).

The first acquisition of signal from the spacecrft is expected at 21:29 GMT

As launch and post launch events unfold leading to spacecraft separation, ESA plans additional live streaming events at 7:00 a.m. EDT (11:00 GMT) and 5:10 p.m. (21:10 GMT)

Spacecraft separation from the Breeze upper stage is expected at about 10 hours, 41 minutes.

The ExoMars 2016 mission is comprised of a pair of European spacecraft named the Trace Gas Orbiter (TGO) and the Schiaparelli entry, descent and landing demonstration lander, built and funded by the European Space Agency (ESA).

Russian is providing the Proton booster and part of the science instrument package.

“The main objectives of this mission are to search for evidence of methane and other trace atmospheric gases that could be signatures of active biological or geological processes and to test key technologies in preparation for ESA’s contribution to subsequent missions to Mars,” says ESA.

ExoMars is Earth’s lone mission to the Red Planet following the two year postponement of NASA’s InSight lander from 2016 to 2018 to allow time to fix a defective French-built seismometer.

ESA reported late today , March 13, that at T-minus 12 hours the Trace Gas Orbiter has been successfully switch on, a telemetry link was established and the spacecrft battery charging has been completed.

The Proton rocket with the encapsulated spacecraft bolted atop were rolled out to the Baikonur launch pad on Friday, March 11 and the launcher was raised into the vertical position.

ESA mission controller then completed a full launch dress rehearsal on Saturday, March 12.

The ExoMars 2016 TGO orbiter is equipped with a payload of four science instruments supplied by European and Russian scientists. It will investigate the source and precisely measure the quantity of the methane and other trace gases.
