Launched into LEO
Lifetime Expectancy: 6-12 months

3. LionSat Mission Timeline

4. Objectives Primary Objectives Secondary Objectives
P1: To map the ram and wake plasma structure surrounding a small satellite.
P2: To collect data on ionospheric plasma in a variety of geophysically interesting locations in low Earth orbit.
P3: To test, on orbit, a miniature RF ion thruster.
Secondary Objectives
S1: To test IP communications for uplink and downlink to a spacecraft in low Earth orbit.

5. Mission Requirements Mission Requirements
M1. The plasma environment mapping throughout the entire perturbed region (i.e., ram and wake) must be resolved to 30±5 degrees about the satellite spin axis.
M2. The electron density and temperature of both the unperturbed and perturbed regions around the nanosatellite must be collected and returned to the ground for a minimum of three separate geophysically meaningful campaigns.
M3. The miniature RF ion thruster must demonstrate a minimum of one hour of continuous operation.
M4. The miniature RF ion thruster must demonstrate a measurable change in the satellite rotation rate.
