NASA’s acting administrator said Tuesday he does not expect Russian cosmonauts to start launching to the International Space Station on U.S. commercial crew vehicles until next year. A proposed agreement with Russia to ensure the space station is always staffed with an international crew is awaiting U.S. government approval.

Concerns about the coronavirus pandemic have prompted officials to postpone the planned March 30 launch of Argentina’s SAOCOM 1B radar observation satellite from Cape Canaveral aboard a SpaceX Falcon 9 rocket, officials said Tuesday.

Six days after SpaceX fired its last Falcon 9 rocket from NASA’s Kennedy Space Center, another launcher rolled to historic pad 39A and ignited its nine Merlin 1D engines at sunset Thursday in preparation for a commercial satellite delivery mission Sunday for Intelsat.
