After a series of delays, including a 24-hour slip prompted by a solar flare, Orbital Science's robotic Cygnus spacecraft is en route to the International Space Station.
A major solar flare has prompted the spaceflight company Orbital Sciences to delay its resupply mission to the International Space Station.
NASA launched a 1,500-pound care package today through Cygnus, its newest unmanned commercial spacecraft that will deliver food and clothing to the International Space Station.
The Antares rocket, built by Orbital Sciences Corp., is set for a first test launch Wednesday evening, weather permitting. Its maker is, like SpaceX, under contract with NASA to ferry cargo to the International Space Station.
