The Cygnus cargo ship is the seventh of 10 planned missions through 2018 under Orbital's space station resupply contract with NASA, worth up to $3.1 billion. The first two space fire experiments took place during previous Cygnus resupply missions. A computer in a blast-proof box will stitch together the images for a full, in-the-round view. Live 360 technology offers advanced capacities that can be used efficiently during the launch of space missions to give viewers a more immersive experience.
The April 18 launch is the third time that Cygnus is boosted by United Launch Alliance's Atlas V. The launch marks the ULA's 71st overall launch of the rocket and the 36th in the spacecraft's 401 configuration.
