The last image #Beresheet spacecraft managed to beam to earth before it crashed on the moons surface.


My solution to the Beresheet spacecraft landing maneuver on the Moon.


Beresheet:
Dirty mass 150 kg
Fuel 199 kg
Mass 349 kg
Thrust 407 N
ISP 318 s
Altitude 22 909 m
vx 1585.50 m/s 
vy -22.90 m/s 

solution:
