What was the goal of Apollo 9?
Apollo 9 was the third manned mission in the Apollo Program and the first flight of the Command/Service Module (CSM) with the Lunar Module (LM). The goal was to test the LM in orbit and practice maneuvering and rendezvous with the CSM.
Why did the command and service modules stay in orbit around the moon?
The Lunar Module could not make the return trip to Earth and the CSM could not land on the moon. As such, the CSM stayed in orbit while the LM traveled to and from the lunar surface.
How many engines Apollo 13?
The CSM (Command Module) had one main engine. The LM (Lunar Module) had a Descent engine and an Ascent engine. Both the CSM and the LM had some tiny steering rockets. These would not be considered "engines" as such as their purpose was not propulsion. That makes three engines. Of course, the Saturn 5 boosters were also engines, but you seemed most interested in the Apollo 13 craft itself, not the boosters that sent it up. In other words, the engines it had during the emergency, not before launch. The Lunar Module descent engine was the one that powered the Apollo 13 home, as the CSM engine could not be fired, due to the lack of electrical power the accident caused.
How did the Apollo mission work?
The manned Apollo missions launched atop a Saturn V rocket to get into Earth orbit. After a couple orbits to get everything configured they performed what is called a TLI (Trans Lunar Injection) burn using the CSM (Command Service Module) engine and coasted through cislunar space between the Earth and the moon for three days. Once they arrived at the moon they performed a second burn of the CSM engine, called the LOI (Lunar Orbit Insertion) burn. This parked them in orbit around the moon. Two of the astronauts on board, the Commander, or CDR, and the Lunar Module Pilot, or LMP) entered the LM (Lunar Module) and separated from the CSM, leaving the Command Module Pilot, or CMP, alone in orbit. The LM then performed its own engine burn to reduce speed and eventually land on the moon. The LM was built in two halves. When the ground mission was over, the CDR and LMP separated the Descent stage of the LM from the Ascent stage, fired the engine, and lifted off from the moon's surface, leaving the Descent Stage on the moon. Once there they reconnected with the CSM, disconnected the LM (which then either crashed into the moon or entered a long period orbit about the sun, depending on the mission), and performed a TEI (Trans Earth Injection) burn, once again using the CSM engine. After another three day coast through cislunar space, the CMP disconnected the Command Module from the Service Module exposing the heat shield on the bottom of the CM, entered Earth's atmosphere, and splashed down into the ocean to be recovered by the US Navy.
How did the astronauts get to the Moon and back?
In very broad terms:The crew launched atop a Saturn V rocket into Earht orbit, which takes 8-10 minutesFrom Earth orbit they fired the rocket on the Apollo Commond/Service Module (CSM) for less than 10 minutesThey then coasted to the moon, a trip that lasts about three days.Once they got near the moon the turned around and fired the CSM engine again to slow back down, entering Lunar orbitWhile in Lunar orbit two members of the crew would enter the LunarModule (LM), close the hatch, disconnect from the CSM, and use the LM's Descent Engine to slow down and then land on the moon's surface.Once the surface missions was complete the crew would fire the LM's Ascent Engine to return to Lunar orbit.In Orbit, they would join up with the CSM which had stayed up there and the two crew members would reenter the CSM and close the hatch.The LM was then disconnected and, as planned, allowed to crash into the moon (the shockwaves of the crash were used to analyze the interior of the moon via science packages the crew left behind on the surface)The crew would fire the CSM engine to exit Lunar orbitThey coasted, once again, all the way back to EarthOnce they got close to Earth they disconnected the Service Module, exposing the heat shield on the bottom of the Command Module.They entered earth's atmosphere and floated down to Earth under parachutes, landing in the oceanThey were then retrieved from the ocean by Navy helicopter and flown to a nearby Navy ship upon which they would sail home.
Which vehicle is used by astronauts travelling to the moon?
There are a few "vehicles" that were used by Apollo astronauts.Saturn 1B rocketsSaturn V rocketsThe Command/Service modules and Lunar Modules: CSM-012 (Apollo 1), CSM-017 & LTA-10R (Apollo 4), CM-020 & SM-014 & LTA2R (Apollo 6), CSM-101 (Apollo 7), CSM-104 & LTA-B (Apollo 8), CSM-104 Gumdrop & LM-3 (Apollo 9), CSM-106 Charlie Brown & LM-4 (Apollo 10), CSM-107 Columbia & LM-5 Eagle (Apollo 11), CSM-108 Yankee Clipper & LM-6 Intrepid (Apollo 12), CSM-109 Odyssey & LM-7 Aquarius (Apollo 13), CSM-110 Kitty Hawk & LM-8 Antares (Apollo 14), CSM-112 Endeavor & LM-10 Falcon (Apollo 15), CSM-113 Casper & LM-11 Orion (Apollo 16), CSM-114 America & LM-12 Challenger (Apollo 17).

What does LM stand for in LM-35 temperature sensor?
linear monolithic
In 1969 what safely transported the first humans to the moon?
The Apollo Command and Service Modules (CSM) as well as the Apollo Lunar Module (LM)
What is lm in lm324?
LM stand for Liner Monolithic ic that is the National Instrunt perfix, I My right
What does CSM stand for in the army?
It's a rank - Command Sergeant Major
What do the 3 letters in the mnemonic CSM stand for?
Circulation. Sensation. Movement
What was Apollo 10 used for?
To be the second to orbit the moon and first to travel the moon with the entire spacecraft configuration. They were called the "dress rehearsal" for the actual lunar landing. They had the same spacecraft, they separated the LM and CSM Stack, and the LM descended to within 8 nautical miles of the moon's surface before aborting the landing (as planned) and rejoining the CSM. This proved that everything short of the actual landing worked.
What does Lm stand for in metric system?
Lick mice
