Rocket Lab’s Photon upper stage completes 3rd of 7 engine firings to get CAPSTONE to Moon
Rocket Lab’s Photon upper stage has now successfully completed the third of seven planned engine burns designed to slowly raise the Earth orbit of NASA’s experimental lunar cubesat CAPSTONE so that it can eventually be sent towards the Moon.
Lunar Photon’s HyperCurie engine will perform a series of orbit raising maneuvers by igniting periodically to increase Photon’s velocity, stretching its orbit into a prominent ellipse around Earth. Six days after launch, HyperCurie will ignite one final time, accelerating Photon Lunar to 24,500 mph (39,500 km/h) and setting it on a ballistic lunar transfer. Within 20 minutes of this final burn, Photon will release CAPSTONE into space for the first leg of the CubeSat’s solo flight. CAPSTONE’s journey to NRHO is expected to take around four months from this point. Assisted by the Sun’s gravity, CAPSTONE will reach a distance of 963,000 miles from Earth – more than three times the distance between Earth and the Moon – before being pulled back towards the Earth-Moon system.
Once in lunar orbit, CAPSTONE will be used to both test operations in that orbit (similar to the one NASA’s Lunar Gateway space station will use) while also demonstrating the use of a cubesat on an interplanetary mission.
