Mission Description

• Successfully launch the Rover and detach from the
  tethering system.
• Image flight and landing site autonomously.
• Accomplish mission under strictmass limitations.

3
Mission Goals

• Design and build an autonomous roverand its
  carrier under strict mass limitation of 1.5 kg.
• Incorporate imaging system on the rover to video
  the fight and the landing site.
• Rover must survive
• high altitude
• extreme cold temperatures
• impact forces during landing

4
NASA Benefits
Prototype development which maybe used during
future missions toMars or the moon. Methods
could lead to future NASA design. Exploring new
methods of rover design, construction, and
deployment.
5
System Requirements

• Rover must meet 1.5 kg mass limitation.
• Rover must image thelanding site.
• Rover must detach/deploy at the landing site.
• Rover must have a drive systemallowing it to
  maneuver on the groundat landing site.

Imaging System

• Image continuously during the flight and after
  landing.
• Modified Panasonic SD Digital Video Camera.
• Extended memory (1GB) capacity capable of
  approximately of 120 minutes of video using
  MPEG-4 video compression.
