Orolia is paid €70 million to provide atomic clocks for the first 12 satellites of the Galileo Second Generation System (G2S), Orolia announced. The funding comes in two contracts, one with ESA and the other with Leonardo. The news comes after the European Commission and ESA chose Orolia’s Skydel GNSS signal simulation core engine for the G2S radiofrequency constellation simulator in May.

Virgin Orbit is planning to expand its participation in the military by competing for tactically responsive launch contracts with Space Force, SpaceNews reports. They are trying to prove that rockets launched from airplanes in flight can be useful for national security.

Masten Space Systems was awarded a Phase II SBIR contract to develop and test a lunar positioning and navigation network prototype, Masten said. The GPS-like solution is part of the Air Force Research Laboratory’s AFWERX program. The network will boost cislunar security, improve landing accuracy and hazard avoidance by providing location tracking for spacecraft and astronauts on the lunar surface.

Investigation uncovered that Firefly Aerospace’s first Alpha rocket had failed due to the shutting down of one of its first-stage engines, Firefly said. The launch took place at Vandenberg Space Force Base in California on 2nd September. The engine shut down just a few seconds after lift-off making the rocket tumble out of control two and a half minutes into the flight.

The Chang’e-5 orbiter module is currently on its way back to the Moon following deep space tests according to reports. Last year, the orbiter delivered a return module containing 1.731 kg of lunar samples to Earth before setting off to deep space. Chang’e-5 orbiter was in orbit around Lagrange point 1 (L1) where it carried out orbit control tests and observations.
