Atlas 5/Cygnus post-launch news conference

Russian flight controllers have given up attempting to salvage a Progress cargo ship loaded with 3 tons of supplies and equipment intended for the International Space Station. Astronaut Scott Kelly, on board the lab for a year-long mission, said Wednesday the Progress will not be docking and instead will plunge back into the atmosphere.

Riding a self-propelled transporter, an Orbital ATK Antares rocket rolled out to it launch pad Thursday on Virginia’s Eastern Shore for final preparations to send a Cygnus supply ship to the International Space Station.

SpaceX’s Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in 10 minutes Friday with a Dragon capsule heading for the International Space Station carrying nearly 7,000 pounds of supplies and experiments.
