Vega 700km orbit 5 degree inclination

Launch opportunity:

This launch is proposed for 2008, so not faesable for our mission!

There is a call for proposals about to come out, for the maiden flight of the E.S.A Vega launch veihicle from Kourou, French Guiana. The web page we've been given is this. They want to fly educational payloads, with six cubesats and six standby cubesats.

The orbit would be approximately circular with a 5^o inclination at an altitude of 700km.

Here is the proton flux for such an orbit:

Here is the electron flux:

Here is the total dosage of one year mission in the same orbit (worst case scenario):

Here is the total dosage for the same length mission, but with a more representative dosage:
