The Astrus Vespera is our newest moon lander and our most advanced uncrewed lander so far.
It uses 8 gimbal-less methalox electric pump-fed engines that can be split into 2 groups of 4 for landing and de-orbit propulsion. It uses togglable gyroscopes and RCS for manoeuvring in space and during landings. It has 8 static solar panels (one mounted on each side) and 8 togglable solar panels (2 per side, on 4/8 sides).
The lander needs to be placed into a 25km lunar orbit before it can be deployed, once deployed it can de-orbit and land with a maximum payload of 600kg. With no payload or adapter, it weighs 4.92 tonnes when fully fueled and with the payloads and adapter it weighs 5.89 tonnes when fully fueled.
By itself, the lander is 2.73m tall and 2.47m in diameter with the landing legs stowed, when they are deployed it is 4.52m in diameter and 3.29m tall. Adding the adapter increases the stowed height to 3.29m and the diameter to 2.5m.
