Fossa Systems is developing an open source satellite, which is set to launch this fall. The FossaSat-1 is is built around an ATmega328P-AU, along with an SX1278 transceiver for telecommunications. The EPS system is based on three SPV1040 MPPT chips and a TC1262 LDO.
SpaceX has completed over 700 tests of the spacecraft's SuperDraco engines. Fired together at full throttle, Crew Dragon's eight SuperDracos can move the spacecraft 0.5 miles—the length of over 7 American football fields lined up end to end—in 7.5 seconds, reaching a peak velocity of 436 mph.
