Study Notes
Mars Missions
- Nearly 60 missions have targeted Mars.
- Just over half of these missions have been successful.
- Most missions involve landers/rovers.
Pathfinder/Sojourner Mission
- Arrived on Mars in 1996.
- Used a combination of techniques for landing: atmospheric slowing, parachutes, and airbags for impact protection.
Terraforming
- Terraforming aims to alter a planet's environment for human habitability.
Martian Atmosphere
- Currently a thin atmosphere, mostly carbon dioxide.
- Similar in thinness to Earth's air at 30 km altitude.
- Occasional strong windstorms occur.
- Liquid water does not exist on the surface due to low atmospheric pressure; there is no liquid water rain /irigiation.
- Haze formed by CO2 crystals.
Martian Channels
- Complex channels observed, appear liquid-formed.
- The thin Martian atmosphere cannot sustain liquid water on the surface.
- An explanation for the channels is that Mars had a thicker atmosphere in the past.
