EXOMARS TRACE GAS ORBITER AND SCHIAPARELLI MISSION (2016)


The first mission of the ExoMars programme, scheduled to arrive at Mars in 2016, consists of a Trace Gas Orbiter plus an entry, descent and landing demonstrator module, known as Schiaparelli. 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.

The Orbiter and Schiaparelli will be launched together in March 2016 on a Proton rocket and will fly to Mars in a composite configuration. By taking advantage of the positioning of Earth and Mars the cruise phase can be limited to about 7 months, with the pair arriving at Mars in October. Three days before reaching the atmosphere of Mars, Schiaparelli will be ejected from the Orbiter towards the Red Planet. Schiaparelli will then coast towards its destination, enter the Martian atmosphere at 21 000 km/h, decelerate using aerobraking and a parachute, and then brake with the aid of a thruster system before landing on the surface of the planet. From its coasting to Mars till its landing, Schiaparelli will communicate with the Orbiter. Once on the surface, the communications of Schiaparelli will be supported from a NASA Relay Orbiter. The ExoMars Orbiter will be inserted into an elliptical orbit around Mars and then sweep through the atmosphere to finally settle into a circular, approximately 400-km altitude orbit ready to conduct its scientific mission.


TRACE GAS ORBITER - SEARCHING FOR SIGNATURE GASES IN THE MARTIAN ATMOSPHERE

The Orbiter spacecraft is designed by ESA, while Roscosmos provides the launch vehicle. A scientific payload with instruments from Russia and Europe will be accommodated on the Orbiter to achieve its scientific objectives. The  Orbiter will perform detailed, remote observations of the Martian atmosphere, searching for evidence of gases of possible biological importance, such as methane and its degradation products. The instruments onboard the Orbiter will carry out a variety of measurements to investigate the location and nature of sources that produce these gases. The scientific mission is expected to begin in December 2017 and will run for five years. The Trace Gas Orbiter will also be used to relay data for the 2018 rover mission of the ExoMars programme and until the end of 2022.

SCHIAPARELLI: AN ENTRY, DESCENT AND LANDING DEMONSTRATOR MODULE
TESTING CRITICAL TECHNOLOGY FOR FUTURE MISSIONS

Schiaparelli, the ExoMars entry, descent and landing demonstrator module will provide Europe with the technology for landing on the surface of Mars with a controlled landing orientation and touchdown velocity. The design of Schiaparelli maximises the use of technologies already in development within the ExoMars programme. These technologies include: special material for thermal protection, a parachute system, a radar Doppler altimeter system, and a final braking system controlled by liquid propulsion.

Schiaparelli is expected to survive on the surface of Mars for a short time by using the excess energy capacity of its batteries. The science possibilities of Schiaparelli are limited by the absence of long term power and the fixed amount of space and resources that can be accommodated within the module; however, a set of scientific sensors will be included to perform limited, but useful, surface science.

KEEPING IN TOUCH FAR FROM HOME

After launch and throughout the cruise phase, the spacecraft unit made up of the Trace Gas Orbiter and Schiaparelli is operated by ESA through the space communications network of ESA's European Space Operations Centre (ESOC).

After separation, the Orbiter will monitor the UHF transmission from Schiaparelli from its coasting to Mars till its landing. A NASA Relay Orbiter will act as a data relay for Schiaparelli during its surface operations. Furthermore, ground-based communication arrays will also track the UHF signal during the entry, descent and landing phases.

ESA will be in full control of the Orbiter during all phases of its mission, including insertion into Mars orbit, orbit control, aerobraking, science operations and Mars communications operations.

Artist's impression of the ExoMars 2016 Trace Gas Orbiter (TGO) and Schiaparelli – the entry, descent and landing demonstrator module.

With a science payload of four instruments - NOMAD, ACS, CaSSIS, and FREND - the TGO will investigate trace gases – those gases that are present in small concentrations in the atmosphere, making up less than 1 per cent of it. There will be particular focus on hydrocarbons and sulphur species, some of which could be signatures of active biological or geological processes, at present or in the past.

The Schiaparelli module carries a small science payload, to study the environment. The payload, called DREAMS, will operate on the surface of Mars for 2–8 sols. In addition, there is an investigation known as AMELIA, for entry and descent science data collection using the spacecraft engineering sensors. A separate instrumentation package, COMARS+, will monitor the heat flux on the back cover of Schiaparelli as it passes through the atmosphere.

The TGO will be launched with Schiaparelli. They will fly in a composite configuration to Mars. Three days before reaching the atmosphere of the Red Planet, Schiaparelli will be ejected from the TGO towards the planet. The TGO will be inserted into an elliptical orbit around Mars and then sweep through the atmosphere – aerobraking – for about a year to finally settle into a circular, approximately 400-km altitude orbit ready to conduct its scientific mission.

A high-gain antenna, with a steerable 2.2m-diameter dish, is used for communication with Earth.

Two solar arrays, each 7.92 m long and 1.74 m wide, will provide the TGO with power during the mission.

ExoMars is a joint endeavour between ESA and Russia's Roscosmos space agency.

“太空巨鼻”将“嗅嗅”火星生命踪迹

  ExoMars痕量气体轨道探测器示意图

  据欧洲空间局网站消息,ExoMars非载人火星探测任务的“痕量气体轨道探测器(TGO)”定于3月从哈萨克斯坦拜科努尔发射场升空,窗口期为14日至25日。用项目科学家豪尔赫·瓦戈的话来说,这个探测器相当于太空中的一个巨大“鼻子”,可用来嗅出火星上的甲烷,并确定其是否由生物过程产生。

  地球大气中的甲烷大多由微生物制造,比如牛和白蚁的肠道细菌。而探测到火星上的甲烷的话,将为火星存在或者曾经存在过某种生命形式的设想提供强有力支持。为此,欧空局与俄罗斯同行联手,希望绘制出一份火星甲烷地图。

  此前的火星任务曾发现大气中低含量的甲烷,而TGO拥有一套高灵敏度光谱仪,即使甲烷水平低至万亿分之几,也能检测出来。方法有两种:一是在黎明和黄昏时观测火星,这时阳光直射探测器,科学家可以获得距离火星地表不同高度的甲烷含量的详细信息;二是向下“看”向火星地表,由此绘制出火星的甲烷热点地图。

  TGO的光谱仪还能够检测出甲烷以外的关键化学物质和气体,以确定火星甲烷是由生命体产生,还只仅仅是地质过程的副产品。瓦戈强调,如果甲烷与其他复杂烃类气体同时存在,比如丙烷或乙烷,这将是表明其与生物过程相关的一个强有力证据;如果找到甲烷的同时还发现二氧化硫(一种与地球上火山活动密切相关的化学产物),则可以肯定甲烷来自地底,是在地质活动中逸出的。

  除了TGO,ExoMars项目还定于2018年发射火星漫游车。因此,此次任务不仅肩负着寻找甲烷和其他痕量气体的重担,还对两年后将要使用的登陆设备包进行测试。据悉,TGO10月份抵达火星轨道后,一个名为“斯基亚帕雷利”(意大利天文学家的名字,最早的火星地图部分由他绘制)的登陆飞船届时也将被释放,这个着陆器将传回其降落时穿越火星大气层的精确信息。

FREND是俄罗斯的成熟仪器,山姆大叔在MAVEN,好奇号等火星探测器上用着呢,怎么也会有问题?

火星探索方面,俄积极参与“ExoMars”火星探索项目,俄科学院空间研究所为衡量气体轨道器模块研制了大气化学光谱综合测定系统和“FREND”中子光谱仪。2016年初,俄将使用“质子-M”火箭发射由欧空局研制的在轨卫星和实验性登陆舱。

Everything is complete on the spacecraft now and the activities with our Russian colleagues are about to start.  Soon the spacecraft will be fixed to the top of the rocket as we step through the preparations to launch for the next 14 days.
While all this is going on in Baikonur another major effort is underway at the Mission Operations Control Centre in Germany.  Teams of engineers are working to prepare the ground control system to receive the first radio signal from the spacecraft after launch and separation from the rocket on the way to Mars.

The ExoMars 2016 spacecraft - consisting of the Trace Gas Orbiter (TGO) and the Schiaparelli entry, descent and landing demonstrator - is in Baikonur, Kazakhstan, preparing for its mid-March launch on a Russian Proton rocket.

This joint European and Russian mission will test key exploration technologies and search for evidence of methane and other rare gases in the martian atmosphere. These gases could result from geological processes or they could be signatures of current biological activity on the planet. Three days before reaching Mars in October, Schiaparelli will separate from the orbiter and coast towards the planet in hibernation mode to reduce power consumption.

This video covers the journey, the orbit of the Trace Gas Orbiter, the separation of the Schiaparelli lander and its 20 000 km/hour descent and eventual landing. It also contains filming at ESA’s European Space and Technology Centre (ESTEC) Mars Yard in the Netherlands.

Learning more about Mars’ water and environment will shed further light on this planet - while knowing the origin of its methane could finally answer the exciting question of whether there is life on Mars.
