The Cygnus spacecraft, named the "S.S. Roger Chaffee," is switching to its internal battery power supply in preparation for liftoff. The supply ship is named for the late astronaut who perished in the Apollo 1 fire with crewmates Gus Grissom and Ed White.

"Given that Lt. Cmdr. Chaffee never made it into space, which was his dream, we decided to name this vehicle the S.S. Roger Chaffee in his honor," said Frank DeMauro, vice president of Northrop Grumman Innovation Systems' space division. "It's something that's very special to us, and it's very special to his family, and to all of the team."

Members of the Chaffee family are present for today's launch from Wallops Island, according to Northrop Grumman.

"That's just something that makes this extra special, so we're looking forward to seeing them here," DeMauro said.

Cygnus separation confirmed! Northrop Grumman's commercial cargo carrier is now flying free from the Antares rocket, on the way to the International Space Station with nearly 7,600 pounds of supplies and experiments.

The supply ship is scheduled to unfurl its two fan-like solar arrays in the next two-and-a-half hours to begin charging batteries for the day-and-a-half trip to the space station.

Анимация смешная - Антарес целиком на орбите. В остальном всё хорошо.
