MRO가 2016년 5월 29일과 10월 20일에 스키아파렐리 착륙선(ExoMars Schiaparelli lander)의 착륙 예정지를 촬영한 사진의 비교.
사진에서 밝은 점은 낙하산의 모습이고, 검은 점은 표면에 충돌한 착륙선인 것으로 추정됨.

The Schiaparelli lander descending to Mars on October 19.


LIVE UPDATES: EXOMARS ARRIVAL AND LANDING


Updates from ESA’s space operations centre as the ExoMars Trace Gas Orbiter approaches and enters orbit around the Red Planet, and the Schiaparelli module lands on its surface.

Updates on this page will cover the following expected milestones:


14 October: TGO final trajectory manoeuvre (08:45 GMT)
16 October: Separation of Schiaparelli from TGO at 14:42 GMT / 16:42 CEST 
17 October: TGO orbit-raising manoeuvre at 02:42 GMT / 04:42 CEST
19 October: TGO Mars orbit insertion and Schiaparelli entry, descent and landing on Mars (atmospheric entry expected 14:42 GMT / 16:42 CEST, landing 14:48 GMT / 16:48 CEST)
20 October: Update on Schiaparelli status; descent images expected 
21+ October: Schiaparelli status reports until end of mission
Note: Times shown above are actual event times at Mars; the one-way signal travel time between Earth and Mars is currently just under 10 minutes.


The events of 16, 19 and 20 October will also be livestreamed here, all other events will be reported on this page and via Twitter from @esaoperations, @ESA_ExoMars, @ESA_TGO and @ESA_EDM, and via the hashtag#ExoMars.

On Wednesday, October 19, the ExoMars 2016 entry, descent and landing demonstrator module, named Schiaparelli, will land on Mars in Meridiani Planum not far from the Opportunity rover. The map shows the seven rovers and landers that have reached the surface of Mars and successfully operated there. The background image is a shaded relief map of Mars created using data from NASA’s Mars Global Surveyor spacecraft.


Artist’s impression showing Schiaparelli separating from the Trace Gas Orbiter and heading for Mars. The lander is named for late 19th century Italian astronomer Giovanni Schiaparelli, who created a detailed telescopic map of Mars. The orbiter will sniff out potentially biological gases such as methane in Mars’ atmosphere and track its sources and seasonal variations. Credit: ESA/ATG medialab.


This image illustrates possible ways methane might get into Mars’ atmosphere and also be removed from it: microbes (left) under the surface that release the gas into the atmosphere, weathering of rock (right) and stored methane ice called a clathrate. Ultraviolet light can work on surface materials to produce methane as well as break it apart into other molecules (formaldehyde and methanol) to produce carbon dioxide.

2012년에 화성에 착륙한 큐리오시티 로버 착륙지의 흔적 변화.


2012년에 화성 표면에 착륙한 큐리오시티 로버의 착륙지의 검은색 흔적이 화성의 대기 변화로 인해서 점차 먼지들에 덮혀서 보이지 않게 되었네요.

Changes in Scars From 2012 Mars Landing.

A series of observations from Mars orbit show how dark blast zones that were created during the August 2012 landing of NASA's Curiosity rover have faded inconsistently.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter made the observations on multiple dates from landing to last month. After fading for about two years, the pace of change slowed and some of the scars may have even darkened again.


Figure 1 is a sequence showing the spacecraft's back shell and parachute. 

Figure 2 sequence shows where the rover itself landed.

Figure 3 is a five-frame sequence of the location where the spacecraft's heat shield hit the ground.
