Orbital Sciences Corporation (registered on the New York Stock Exchange as ORB, though commonly referred to as Orbital) is an American company which specializes in the manufacturing and launch of small- and medium-class space and rocket systems. Their client base includes the likes of the US Department of Defense and NASA. A pretty sizeable company, counting around 3800 employees of which half are engineers and scientists, Orbital was founded in 1982. The company conducted their 500th mission back in 2006 already and are currently projected to do more than a billion dollars in annual revenue.
Analysing the company very top-level, it consists of three segments. Launch Vehicles is where they develop rockets and engines of all sorts for different purposes, military and civilian. Satellite and Space Systems is where their geosynchronous Earth orbit communication satellites and other space-based communications service come from. Perhaps the most interesting – definitely for our focus here – is the Advanced Space Program where they besides developing small and medium class satellites for national security space systems also keep themselves busy with working on projects for human space flight and planetary exploration.
Orbital is involved with two prominent NASA programs: the Commercial Orbital Transportation Services (COTS)/Commercial Resupply Services (CRS) programs and the Orion Crew Exploration Vehicle (CEV). More on those another time but the long story short, NASA started using private companies (both SpaceX and Orbital are contracted) recently for cost-effective supply missions to and from the International Space Station and low-Earth orbit. The Obama Administration is looking to expand this approach with partnerships to send NASA astronauts to the space station as soon as 2017.
Orbital launched its new Antares® rocket (a two-stage launch vehicle) for the first time in 2013 – see above for a fascinating time lapse video of its preparation for launch – and its Cygnus™ cargo logistics spacecraft is next scheduled to travel to the ISS mid December. They are pretty active on social media, and it is definitely worth checking out their YouTube channel as well where you can find gems like below’s highlights of their Cygnus demo mission – electronic dance tunes included. Definitely a company we will be following closely!
