Orbital Sciences Corporation’s Antares rocket was rolled out to the Mid-Atlantic Regional Spaceport’s Pad-0A at Wallops Flight Facility in preparation for a test flight targeted for later this month. Antares is designed to propel a Cygnus cargo spacecraft laden with experiments and supplies to the International Space Station. This test won’t include the spacecraft or a rendezvous with the space station. That full-up demonstration flight is planned for later this year. Also, first light for AMS, Materials in Space, Observing Earth, Farthest Supernova Yet, Blowing in the Wind, Earth Month 2013 and more!
