ExoMars ESA mission insignia
ExoMars (Exobiology on Mars) is a two-part astrobiology project to search for evidence of life on Mars, a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos. The first part, launched in 2016, placed a trace gas research and communication satellite into Mars orbit and released a stationary experimental lander (which crashed). The second part is planned to launch in 2020, and to land the ExoMars rover on the surface, supporting a science mission that is expected to last into 2022 or beyond.
ExoMars goals are to search for signs of past life on Mars, investigate how the Martian water and geochemical environment varies, investigate atmospheric trace gases and their sources and by doing so demonstrate the technologies for a future Mars sample return mission. The mission will search for ancient biosignatures of Martian life, employing several spacecraft elements to be sent to Mars on two launches.
The ExoMars Trace Gas Orbiter (TGO) and a test stationary lander called Schiaparelli were launched on 14 March 2016. TGO entered Mars orbit on 19 October 2016 and will proceed to map the sources of methane (CH
4) and other trace gases present in the Martian atmosphere that could be evidence for possible biological or geological activity. The TGO features four instruments and will also act as a communications relay satellite. The Schiaparelli experimental lander separated from TGO on 16 October and was maneuvered to land in Meridiani Planum, but it crashed on the surface of Mars. The landing was designed to test new key technologies to safely deliver the 2020 rover mission.
In 2020, a Roscosmos-built lander (ExoMars 2020 surface platform) is to deliver the ESA-built ExoMars Rover to the Martian surface. The rover will also include some Roscosmos built instruments. The second mission operations and communications will be led by ALTEC's Rover Control Centre in Italy.
History[edit | hide all | hide | edit source]
Since its inception, ExoMars has gone through several phases of planning with various proposals for landers, orbiters, launch vehicles, and international cooperation planning, such as the defunct 2009 Mars Exploration Joint Initiative (MEJI) with the United States. Originally, the ExoMars concept consisted of a large robotic rover being part of ESA's Aurora Programme as a Flagship mission and was approved by the European Space Agency ministers in December 2005. Originally conceived as a rover with a stationary ground station, ExoMars was planned to launch in 2011 aboard a Russian Soyuz Fregat rocket.
ExoMars was begun in 2001 as part of the ESA Aurora program for the human exploration of Mars. That initial vision called for rover in 2009 and later a sample return mission. Another mission intended to support the Aurora program is a Phobos sample return mission. In December 2005, the different nations composing the ESA gave approval to the Aurora program and to ExoMars. Aurora is an optional program and each state is allowed to decide which part of the program they want to be involved in and to what extent (e.g. how much funds they want to put into the program). The Aurora program was initiated in 2002 with support of twelve nations: Austria, Belgium, France, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland, the United Kingdom and Canada
In 2007, Canadian-based technology firm MacDonald Dettwiler and Associates Ltd. (MDA) was selected for a one-million-euro contract with EADS Astrium of Britain to design and build a prototype Mars rover chassis for the European Space Agency. Astrium was also contracted to design the final rover.
On July 2009 NASA and ESA signed the Mars Exploration Joint Initiative, which proposed to utilise an Atlas rocket launcher instead of a Soyuz, which significantly altered the technical and financial setting of the ExoMars mission. On 19 June, when the rover was still planned to piggyback the Mars Trace Gas Orbiter, it was reported that a prospective agreement would require that ExoMars lose enough weight to fit aboard the Atlas launch vehicle with a NASA orbiter.
Then the mission was combined with other projects to a multi-spacecraft mission divided over two Atlas V-launches: the ExoMars Trace Gas Orbiter (TGO) was merged into the project, piggybacking a stationary meteorological lander slated for launch in January 2016. It was also proposed to include a second rover, the MAX-C.
In August 2009 it was announced that the Russian Federal Space Agency (now Roscosmos) and ESA had signed a contract that included cooperation on two Mars exploration projects: Russia's Fobos-Grunt project and ESA's ExoMars. Specifically, ESA secured a Russian Proton rocket as a "backup launcher" for the ExoMars rover, which would include Russian-made parts.
On 17 December 2009, the ESA governments gave their final approval to a two-part Mars exploration mission to be conducted with NASA, confirming their commitment to spend €850 million ($1.23 billion) on missions in 2016 and 2018.
In April 2011, because of a budgeting crisis, a proposal was announced to cancel the accompanying MAX-C rover, and fly only one rover in 2018 that would be larger than either of the vehicles in the paired concept. One suggestion was that the new vehicle would be built in Europe and carry a mix of European and U.S. instruments. NASA would provide the rocket to deliver it to Mars and provide the sky crane landing system. Despite the proposed reorganisation, the goals of the 2018 mission opportunity would have stayed broadly the same.
Under the FY2013 Budget President Obama released on 13 February 2012, NASA terminated its participation in ExoMars due to budgetary cuts in order to pay for the cost overruns of the James Webb Space Telescope. With NASA's funding for this project completely cancelled, most of these plans had to be restructured.
On 14 March 2013, representatives of the ESA and the Russian space agency (Roscosmos), signed a deal in which Russia became a full partner. Roscosmos will supply both missions with Proton launch vehicles with Briz-M upper stages and launch services, as well as an additional entry, descent and landing module for the rover mission in 2018. Under the agreement, Roscosmos was granted three asking conditions:
- Roscosmos will contribute two Proton launch vehicles as payment for the partnership.
- The Trace Gas Orbiter payload shall include two Russian instruments that were originally developed for Fobos-Grunt.
- All scientific results must be intellectual property of the European Space Agency and the Russian Academy of Sciences (i.e. Roscosmos will have full access to research data).
ESA had originally cost-capped the ExoMars projects at €1 billion, (USD 1.3 billion) but the withdrawal of the U.S. space agency (NASA) and the consequent reorganisation of the ventures will probably add several hundred million euros to the sum so far raised. So on March 2012, member states instructed the agency's executive to look at how this shortfall could be made up. One possibility is that other science activities within ESA may have to step back to make ExoMars a priority. On September 2012 it was announced that new ESA members, Poland and Romania will be contributing up to €70 million to the ExoMars mission. ESA has not ruled out a possible partial return of NASA to the 2018 portion of ExoMars, albeit in a relatively minor role.
Russia's financing of ExoMars could be partially covered by insurance payments of 1.2 billion rubles ($40.7 million USD) for the loss of Fobos-Grunt, and reassigning funds for a possible coordination between the Mars-NET and ExoMars projects. On 25 January 2013, Roscosmos fully funded the development of the scientific instruments to be flown on the first launch, the Trace Gas Orbiter (TGO).
As of March 2014, the lead builder of the ExoMars rover, the British division of Airbus Defence and Space, had started procuring critical components, but the 2018 rover mission was still short by more than 100 million euros, or $138 million. The wheels and suspension system are paid by the Canadian Space Agency and are being manufactured by MDA Corporation in Canada.
Status[edit | hide | edit source]
In January 2016 it was announced that the financial situation of the 2018 mission 'might' require a 2-year delay. Italy is the largest contributor to ExoMars, and the UK is the mission's second-largest financial backer.
The rover was scheduled to launch in 2018 and land on Mars in early 2019, but in May 2016 ESA announced that the launch would occur in 2020 due to delays in European and Russian industrial activities and deliveries of the scientific payload.
2016 first spacecraft launch[edit | hide | edit source]
The spacecraft containing ExoMars Trace Gas Orbiter (TGO) and Schiaparelli launched on 14 March 2016 (Livestream began at 08:30 GMT [03:30 AM EDT]). Four rocket burns occurred in the following 10 hours before the descent module and orbiter were released. Signal from the Orbiter was successfully received at 21:29 GMT of the same day, which confirmed that the launch was fully successful and the spacecraft is on its way to Mars. Shortly after separation from the probes, the Briz-M upper booster stage possibly exploded a few kilometers away, however apparently without damaging the orbiter or lander. The spacecraft, which housed the Trace Gas Orbiter and the Schiaparelli lander, took its nominal orbit towards Mars and was seemingly in working order. Over the next two weeks, controllers continued to check and commission its systems, including the power, communications, startrackers, and guidance and navigation system.
Mission objectives[edit | hide | edit source]
- to search for possible biosignatures of past Martian life.
- to characterise the water and geochemical distribution as a function of depth in the shallow subsurface.
- to study the surface environment and identify hazards to future manned missions to Mars.
- to investigate the planet's subsurface and deep interior to better understand the evolution and habitability of Mars.
- achieve incremental steps ultimately culminating in a sample return flight.
The technological objectives to develop are:
Mission profile[edit | hide | edit source]
ExoMars is a joint programme of the European Space Agency (ESA) and the Russian space agency Roscosmos. According to current plans, the ExoMars project will comprise four spacecraft: two stationary landers, one orbiter and one rover. All mission elements will be sent in two launches using two heavy-lift Proton rockets.
|Contributing agency||First launch in 2016||Second launch in 2020|
|Proton rocket||Proton rocket|
|Two instrument packages for the TGO||Russian-built landing system and surface science platform will deliver the rover to the surface. Russia will provide various scientific instruments for the lander and rover.|
|ESA||ExoMars Trace Gas Orbiter||ExoMars rover, and various scientific instruments on the rover|
|Schiaparelli EDM lander|
The two landing modules and the rover will be sterilised in order not to contaminate the planet with Earth life forms. Cleaning will require a combination of sterilising methods, including ionising radiation, UV radiation, and chemicals such as ethyl and isopropyl alcohol. (see Planetary protection).
Trace Gas Orbiter[edit | hide | edit source]
The Trace Gas Orbiter (TGO) is a Mars telecommunications orbiter and atmospheric gas analyzer mission that was launched on 14 March 2016. The spacecraft arrived in the Martian orbit in October 2016. It delivered the ExoMars Schiaparelli EDM lander and then proceed to map the sources of methane on Mars and other gases, and in doing so, help select the landing site for the ExoMars rover to be launched in 2020. The presence of methane in Mars' atmosphere is intriguing because its likely origin is either present-day life or geological activity. Upon the arrival of the rover in 2021, the orbiter would be transferred into a lower orbit where it would be able to perform analytical science activities as well as provide the Schiaparelli EDM lander and ExoMars rover with telecommunication relay. NASA provided an Electra telecommunications relay and navigation instrument to ensure communications between probes and rovers on the surface of Mars and controllers on Earth. The TGO would continue serving as a telecommunication relay satellite for future landed missions until 2022.
Schiaparelli EDM lander[edit | hide | edit source]
The Entry, Descent and Landing Demonstrator Module (EDM) called Schiaparelli, was intended to provide the European Space Agency (ESA) and Russia's Roscosmos with the technology for landing on the surface of Mars. It was launched together with the ExoMars Trace Gas Orbiter (TGO) on 14 March 2016 and was scheduled to land softly on 19 October 2016. No signal indicating a successful landing was received, and on 21 October 2016 NASA released a Mars Reconnaissance Orbiter image showing what appears to be the lander crash site. The lander was equipped with a non-rechargeable electric battery with enough power for four sols. The soft landing should have taken place on Meridiani Planum during the dust storm season, which would have provided a unique chance to characterise a dust-loaded atmosphere during entry and descent, and to conduct surface measurements associated with a dust-rich environment.
Once on the surface, it was to measure the wind speed and direction, humidity, pressure and surface temperature, and determine the transparency of the atmosphere. It carried a surface payload, based on the proposed meteorological DREAMS (Dust Characterisation, Risk Assessment, and Environment Analyser on the Martian Surface) package, consists of a suite of sensors to measure the wind speed and direction (MetWind), humidity (MetHumi), pressure (MetBaro), surface temperature (MarsTem), the transparency of the atmosphere (Optical Depth Sensor; ODS), and atmospheric electrification (Atmospheric Radiation and Electricity Sensor; MicroARES). The DREAMS payload was to function for 2 or 3 days as an environmental station for the duration of the EDM surface mission after landing.
Russian landing system[edit | hide | edit source]
The second mission, scheduled for launch in July 2020, will have an 1800 kg Russian-built landing platform system derived from the 2016 Schiaparelli EDM lander, to place the ExoMars rover on the surface of Mars. This lander platform will be built 80% by the Russian company Lavochkin, and 20% by ESA. Lavochkin will produce most of the landing system's hardware, while ESA will handle elements such as the guidance, radar and navigation systems. Lavochkin's current landing strategy is to use two parachutes; one will open while the module is still moving at supersonic speed, and another will deploy once the probe has been slowed down to subsonic velocity. The heat shield will eventually fall away from the entry capsule to allow the ExoMars rover, riding its retro-rocket-equipped lander, to come for a soft landing on legs or struts. The surface platform lander will then deploy ramps for the rover to drive down.
Surface platform[edit | hide | edit source]
After landing on Mars in 2021, the rover will descend from the platform via a ramp. The platform is expected to image the landing site, monitor the climate, investigate the atmosphere, analyse the radiation environment, study the distribution of any subsurface water at the landing site, and perform geophysical investigations of the internal structure of Mars. Following a March 2015 request for the contribution of scientific instruments for the landing system, there will be four instruments; the two European-led instruments selected are:
- the Lander Radioscience experiment (LaRa) will study the internal structure of Mars, and will make precise measurements of the rotation and orientation of the planet by monitoring two-way Doppler frequency shifts between the surface platform and Earth. It will also detect variations in angular momentum due to the redistribution of masses, such as the migration of ice from the polar caps to the atmosphere.
- the HABIT (HabitAbility: Brine, Irradiation and Temperature) package will investigate the amount of water vapour in the atmosphere, daily and seasonal variations in ground and air temperatures, and the UV radiation environment.
- two Russian-led instruments will monitor pressure and humidity, UV radiation and dust, the local magnetic field and plasma environment.
Rover[edit | hide | edit source]
Instrumentation will consist of the exobiology laboratory suite, known as "Pasteur analytical laboratory" to look for signs of biomolecules and biosignatures from past life. Among other instruments, the rover will also carry a 2-metre (6.6 ft) sub-surface core drill to pull up samples for its on-board laboratory. The rover will have a mass of about 207 kg (456 lb).
The ExoMar's rover includes the Pasteur instrument suite, including the Mars Organic Molecule Analyzer (MOMA), MicrOmega-IR, and the Raman Laser Spectrometer (RLS). Examples of external instruments on the rover incude:
Landing site selection[edit | hide | edit source]
A primary goal when selecting the rover's landing site is to identify a particular geologic environment, or set of environments, that would support —now or in the past— microbial life. The scientists prefer a landing site with both morphologic and mineralogical evidence for past water. Furthermore, a site with spectra indicating multiple hydrated minerals such as clay minerals is preferred, but it will come down to a balance between engineering constraints and scientific goals.
Engineering constraints call for a flat landing site in a latitude band straddling the equator that is only 30° latitude from top to bottom because the rover is solar-powered and will need best sunlight exposure. The landing module carrying the rover will have a landing ellipse that measures about 105 km by 15 km. Scientific requirements include landing in an area with 3.6 billion years old sedimentary rocks that are a record of the past wet habitable environment. The year before launch, the European Space Agency will make the final decision. By March 2014, the long list was:
Following additional review by an ESA-appointed panel, four sites, all of which are located relatively near the equator, were formally recommended in October 2014 for further detailed analysis:
The delay of the rover mission to 2020 from 2018 meant that Oxia Planum was no longer the only favourable landing site due to changes in the possible landing ellipse. Both Mawrth Vallis and Aram Dorsum, surviving candidates from the previous selection, could be reconsidered. ESA convened further workshops to re-evaluate the three remaining options and in March 2017 selected two sites to study in detail;
The final selection is scheduled to occur approximately a year before launch.
