Something is growing at the old landing sites, more and more at a time, and each holds out only a few hours. Find them (drag the Moon), fly back, and bomb the growth before it takes the station.

Lunar Strike
Something is growing at the old Moon landing sites. Your orbiter circles 400 km up, on a real orbit, and its bombs fall along real orbits too. Save the stations before their clocks run out.
Up / Down turn your orbit towards a station
Left / Right turn the ship: the crosshair circles it
Shift + Up / Down throw further / nearer
Space drop, when the crosshair turns green over a station
Every station is a real landing site, from Luna 9 to Blue Ghost. Keyboard needed; sound on. Moon image: NASA SVS (LRO).
