Meet Stratolaunch's Family Of Space Launch Vehicles For Its Huge 'Roc'
Mothership:


"Space launch firm Stratolaunch has unveiled ambitious plans for four
different
launch vehicles, including a reusable space plane, to go along with its
massive
carrier aircraft. The company's goal is to use the multi-tier concept to
provide a
cost-effective and relatively quick means of putting payloads weighing more
than
13,000 pounds into orbit and potentially bringing other cargo, or even
personnel,
to and from the Earth's surface, all of which could be especially useful for
military applications.

The Washington state-headquartered company, which Microsoft co-founder Paul
Allen,
set up in 2011, announced its latest vision for the Stratolaunch system on
Aug.
20, 2018. The planned family of launch vehicles will include Orbital
Sciences
Corporation's Pegasus XL, followed by a Medium Launch Vehicle (MLV), a more
capable Medium Launch Vehicle-Heavy (MLV-H), and finally, a space plane
known as
"Black Ice.""
