A first from UP Aerospace on November 6, 2015 – perfectly timed footage of the Maraia Earth Return Capsule‘s booster separation, captured 75 miles (120 km) above Earth by one of the four cameras attached to the multistage rocket and capsule. More on the launch from Space.com:
A team from Purdue University also tested a new “green” propellant on the Nov. 6 flight. The rocket industry is interested in using less toxic alternatives to conventional fuels such as hydrazine, and the Purdue researchers captured video of their fuel to see how it behaves in the near-weightless environment of space.
