Mission

QB50-ChartThe QB50 mission will demonstrate the possibility of launching a network of 50 CubeSats built by Universities Teams all over the world as a primary payload on a low-cost launch vehicle to perform first-class science in the largely unexplored lower thermosphere.

Space agencies are not pursuing a multi-spacecraft network for in-situ measurements in the lower thermosphere because the cost of a network of 50 satellites built to industrial standards would be extremely high and not justifiable in view of the limited orbital lifetime. No atmospheric network mission for in-situ measurements has been carried out in the past or is planned for the future. A network of satellites for in-situ measurements in the lower thermosphere can only be realised by using very low-cost satellites, and CubeSats are the only realistic option.

Status

Precursor Flights, the first two satellites are QB50p1 and QB50p2 and will be launched June 19 at 19:11 UTC with a Dnepr LV from Yasny.

QB50p1 (FUNcube-3 payload)

FUNcube-3 is the transponder only payload on the QB50 precursor CubeSat “QB50P1″. This mission is now scheduled to launch on June 19 on a Dnepr launch vehicle from Dombarovsky near Yasny. The launch time has been quoted as 19:11:11 UT but this has not yet been confirmed. The initial beacon signals, from the main transceiver, are also expected to be AX.25, 1200 bps BPSK packets on 145.815 MHz.
