Privately-Manufactured Rocket Antares Nearing Launch [INFOGRAPHIC]

After more than a year of delays, the Antares rocket was rolled out onto its Virginia coast launch pad on Saturday in preparation for the first of two test launches, the first of which is scheduled for April 17. Should everything go according to plan, the rocket, developed by aerospace firm Orbital Sciences Corp., will work ferrying cargo to the International Space Station (ISS) as part of a $1.9 billion deal with NASA.
