Space News reports that satellite manufacturer Terran Orbital “has signed an agreement with French aerospace giant Safran to explore U.S.-based production of satellite propulsion systems, the companies announced June 23.” Under the agreement, Safran Electronics & Defense and Terran Orbital “will investigate opportunities and prerequisites for the production of electric propulsion systems for satellites based on Safran’s PPSX00 plasma thruster.” The PPSX00 “is a hall effect plasma thruster, recently introduced by Safran for the low Earth orbit satellite market.” Safran said, “Plasma propulsion has become the go-to solution for satellite positioning, orbital transfer and stationkeeping, because it offers significant weight savings over conventional chemical propulsion.”

ULA’s Delta 4 Heavy Launches NRO Satellite
Space News reports that United Launch Alliance “launched a classified National Reconnaissance Office spy satellite on a Delta 4 Heavy rocket June 22 at 5:18 a.m. Eastern from Space Launch Complex-37 (SLC-37) at Cape Canaveral Space Force Station, Florida.” It was ULA’s second attempt “of this launch that had been previously scheduled for June 21 but was delayed, the company said, ‘due to an issue with a ground systems pneumatic valve.’” About four minutes into flight, “the outer boosters of the three-core Delta 4 Heavy separated.” The second stage “separated about two minutes later.” This mission was “ULA’s first launch of 2023.” The company in May 2019 “received a U.S. Air Force contract to launch NROL-68.” The Delta 4 Heavy configuration “first launched in December 2004.” Each of the Delta 4 Heavy’s common booster cores “is powered by Aerojet [Rocketdyne’s] RS-68A main engines.” The Delta cryogenic second stage “is powered by an RL10C-2-1 engine.”
