Moonshot Three Letter Acronyms (TLA) + others AOS = Acquisition of signal CM = Command Module CSM = Command Service Module EVA = Extravehicular Activity LEM = Lunar Excursion Vehicle LOI = Lunar Orbit Insertion LOS = Loss of Signal PTC = Passive Thermal Control SPS = Service Propulsion System TEI = Trans Earth Injection TLI = Trans Lunar Injection
Milestones to the Moon… LOI burn TLI burn Stage 3 sep burn PTC during translunar flightt LEM docking
It takes 3 days for translunar flight, so shoot where moon is GOING to be…. 120 Miles! TLI burn 248,000 miles Location of moon at TLI burn
Milestones back to Earth… Rentry (34,000 mph) Jettison CM LEM undocking TEI burn PTC during translunar flight
