Video: Post-launch news conference

A Russian Progress resupply and refueling craft launched Monday from the Baikonur Cosmodrome in Kazakhstan, riding a Soyuz booster into orbit on a perfectly-timed departure that set the stage for an on-target docking with the International Space Station less than four hours later.

Viasat has modified an existing contract with Arianespace to launch one of the company’s next-generation broadband Internet satellites on Europe’s next-generation Ariane 6 rocket, rather than on-board an Ariane 5 launcher, officials announced Monday.

Watch the pre-launch news conference held Thursday at NASA’s Kennedy Space Center to preview liftoff of the agency’s TDRS-M data relay satellite aboard a United Launch Alliance Atlas 5 rocket from Cape Canaveral.
