Yesterday, when in the U.S.A. it was afternoon, the Antares rocket was successfully launched in its first test flight, referred to as A-ONE, from the Mid-Atlantic Regional Spaceport (MARS) at NASA’s Wallops Flight Facility. At its top there was a dummy mass that was meant to simulate the Cygnus spacecraft that is to be launched atop the rocket in its actual missions. In the previous days, the launch was postponed due to a hardware problem and bad weather.
