Past, Present, and Future Missions to Mars
• early on most missions to Mars failed
• 25 missions from 1960-1970
• only 17 missions since

Mars Exploration Program Analysis Group
(MEPAG)
• Broke priorities of Mars exploration into 4 goals:
• Life
• Climate
• Geology
• Future Human Exploration
![Page 8: Mars Exploration By Jacob Stinar. Water on Mars](https://reader035.vdocument.in/reader035/viewer/2022062300/56649d625503460f94a44ef2/html5/thumbnails/8.jpg)
Life
• Determine if Mars was ever habitable for life or whether habitable environments exist on Mars now
• Look for sources and distribution of organic molecules on Mars, mainly carbon.
• After finding places where life may be or may have been on Mars go look for that life
![Page 9: Mars Exploration By Jacob Stinar. Water on Mars](https://reader035.vdocument.in/reader035/viewer/2022062300/56649d625503460f94a44ef2/html5/thumbnails/9.jpg)
Climate
• Study the Martian atmosphere, present Martian climate, and climate processes on Mars.
• Study how the climate on Mars has changed over time.
• Examine polar, glacial, and periglacial processes
![Page 10: Mars Exploration By Jacob Stinar. Water on Mars](https://reader035.vdocument.in/reader035/viewer/2022062300/56649d625503460f94a44ef2/html5/thumbnails/10.jpg)
Geological
• Examine the geologic processes that have shaped the surface of Mars.
• Determine the interior structure and composition of Mars.
• Understand the origin, composition, and dynamics of Phobos and Deimos.
![Page 11: Mars Exploration By Jacob Stinar. Water on Mars](https://reader035.vdocument.in/reader035/viewer/2022062300/56649d625503460f94a44ef2/html5/thumbnails/11.jpg)
Future Human Exploration
• Gather knowledge about Mars in order to design a safe cost effective mission to Mars
• Test the technology to make it safer and less expensive
• Study the Martian atmosphere critical for safe operation of the spacecraft

Southern Polar Ice Cap• Image taken by the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) on the Mars Express Orbiter.
• Estimated the water in the Southern Polar Cap would cover the entire surface in 11 meters of water.

Mars Reconnaissance Orbiter (MRO)
• Went into orbit around Mars in March 2006
• Primary mission was to study the history of water on Mars to see if water was present on Mars for long enough to support life
![Page 14: Mars Exploration By Jacob Stinar. Water on Mars](https://reader035.vdocument.in/reader035/viewer/2022062300/56649d625503460f94a44ef2/html5/thumbnails/14.jpg)
MRO Instruments• HiRise camera which takes high resolution images of selected areas
with resolution of 25 centimeters per pixel.• Context Camera (CTX) which takes wide angle images of HiRise
image locations• Mars Color Imager (MARCI) monitors clouds and dust storms• CRISM take spectrums in the optical to near-infrared to identify
minerals on the surface• MCS detects variations in temperature, dust, and water vapor in the
atmosphere• SHARAD uses radar to see water ice is present under the surface.
It works from 1 meter down upwards to 1 kilometer down.• Now MRO is also used to relay signals from spacecraft on the
surface with it’s large 3 meter antenna and to scout out landing sites for Mars Landers such as Phoenix and Mars Science Laboratory.

Mars Exploration Rovers Spirit and Opportunity
• Spirit is making preparations for the winter, however it was unable to increase the tilt angle of it’s solar panels toward the Sun.
• It may lose contact with the Earth for a few months due to low power.
• The rover team programmed Spirit to take images to study winds at the surface and positioned it’s arm to study atmospheric composition when it has enough power.
•Opportunity is located near the equator and is not having power issues.

Mars Odyssey
• Launched in April, 2001
• Main objective is to study the composition Mars’ surface and look for shallow buried ice and water by looking at Hydrogen in the soil
• Also serves as a relay communication for Mars’ Landers such as Phoenix.
• Listen for Phoenix earlier in the week and heard nothing. Will try again in April.

Future Missions: Mars Science Laboratory (MSL)
• Set to launch in fall 2011• Largest most mobile rover yet• Can move 90 meters in one day• Can drive over obstacles 75 centimeters high• Examine samples of Martian soil for climate
geological history• Test for building blocks of life

Mars Atmosphere and Volatile Evolution Mission (MAVEN)
• Set to launch in 2013• Will study the current
loss of atmosphere from Mars to understand it past
• Will study the interaction between upper atmosphere and solar wind
