What were the stages of Apollo 11?
The Apollo spacecraft had three parts: a command module (CM) with a cabin for the three astronauts, the only part that returned to Earth; a service module (SM), which supported the command module with propulsion, electrical power, oxygen, and water; and a lunar module (LM) that had two stages—a descent stage for …
What were the three main parts of the Apollo 13 spacecraft?
The spacecraft was in three parts: The conical Command Module where the crew ate and slept on its way to the moon and home; the Service Module, supplying electricity, maneuvering power and thrust to get home from lunar orbit, and water to the spacecraft; and the Lunar Module, or LM, a two-part, totally self-contained …
What is the name of the Apollo mission that failed to land on the moon?
Apollo 13 (April 11 – 17, 1970) was the seventh crewed mission in the Apollo space program and the third meant to land on the Moon. The craft was launched from Kennedy Space Center on April 11, 1970, but the lunar landing was aborted after an oxygen tank in the service module (SM) failed two days into the mission.
How much delta-v does a satellite have?
For example, although more fuel is needed to transfer a heavier communication satellite from low Earth orbit to geosynchronous orbit than for a lighter one, the delta-v required is the same….Earth–Moon space—low thrust.
| From | To | Delta-v (km/s) |
|---|---|---|
| Earth–Moon Lagrangian 1 (EML-1) | Geostationary Earth orbit (GEO) | 1.4–1.75 |
How much delta-v landed on the moon?
The delta-v required to go from Low Earth Orbit (LEO) (at an altitude of 250 km) to the lunar surface is ~5.9 km/s. However, since the launch vehicle can put the spacecraft on a trajectory that intersects with the Moon’s orbit, the journey starts from a distance farther than LEO.
How do you calculate delta-v?
- “How do you calculate Delta V?”
- The term “delta” means “change,” and in this context, “V” means “velocity.” So “delta V” means the change in velocity. So you simply subtract the initial velocity from the final velocity. That would be the change in velocity.
- But “delta V” just means “change in velocity,” or V2 – V1.
