| Oxygen | 100 cubic feet per astronaut per day |
| Medical supplies | As needed |
| Hygiene products | As needed |
| Clothing | As needed |
Launch Vehicle
The Saturn V was the launch vehicle used to launch the Apollo missions to the Moon. It was a massive rocket, standing over 360 feet tall and weighing over 6 million pounds. The Saturn V consisted of three stages: the first stage was the S-IC, which burned liquid oxygen and kerosene to produce 7.5 million pounds of thrust; the second stage was the S-II, which burned liquid hydrogen and oxygen to produce 2 million pounds of thrust; and the third stage was the S-IVB, which burned liquid hydrogen and oxygen to produce 1 million pounds of thrust. The Saturn V was able to launch the Apollo spacecraft into low Earth orbit, where it would then ignite its own engines to send it on its journey to the Moon.
Ascent to Space
After the Apollo spacecraft was launched into orbit, it would begin its ascent to the Moon. The spacecraft would use its own engines to accelerate to a speed of about 25,000 miles per hour. This would take about three days, during which time the spacecraft would travel about 250,000 miles. As the spacecraft approached the Moon, it would enter the Moon’s gravitational pull and begin to orbit the Moon. The spacecraft would then use its engines to slow down and enter a lower orbit around the Moon. From this orbit, the Apollo astronauts would be able to land on the Moon’s surface.
Lunar Orbit Insertion
Once the Apollo spacecraft entered lunar orbit, it would need to perform a maneuver called lunar orbit insertion (LOI) in order to establish a stable orbit around the Moon. LOI was a complex maneuver that required the spacecraft to fire its engines in a precise sequence in order to slow down and enter a circular orbit around the Moon. If LOI was not performed correctly, the spacecraft could end up crashing into the Moon or flying back into space.
The LOI maneuver was typically performed in two steps. In the first step, the spacecraft would fire its engines to slow down and enter an elliptical orbit around the Moon. The spacecraft would then coast for a period of time, allowing the Moon’s gravity to pull it into a more circular orbit. In the second step, the spacecraft would fire its engines again to adjust its orbit and establish a stable circular orbit around the Moon.
| Maneuver | Purpose |
|—|—|
| LOI-1 | Slows the spacecraft and inserts it into an elliptical orbit around the Moon |
| LOI-2 | Adjusts the spacecraft’s orbit and establishes a stable circular orbit around the Moon |
Trajectory Adjustments and Orbit Insertion
Once the spacecraft is on its way to the Moon, it will need to make several trajectory adjustments to ensure it arrives at the correct time and location. These adjustments are typically made using small rocket burns, which can change the spacecraft’s speed and/or direction.
Lunar Orbit Insertion
Once the spacecraft arrives at the Moon, it will need to insert itself into lunar orbit. This is done by firing the spacecraft’s engine to slow it down and allow the Moon’s gravity to capture it. The spacecraft will then orbit the Moon for a period of time, typically several months or years, before landing.
Lunar Orbit Parameters
The parameters of the spacecraft’s lunar orbit are carefully selected to ensure that it remains stable and does not interfere with other spacecraft or celestial bodies. The following table lists the typical parameters for a lunar orbit:
| Parameter | Value |
|---|---|
| Apoapsis (highest point of orbit) | 100 km |
| Periapsis (lowest point of orbit) | 50 km |
| Inclination (angle of orbit relative to Moon’s equator) | 0 degrees |
| Eccentricity (ellipticity of orbit) | 0 |
| Orbital period | 2 hours |
Lunar Descent and Landing Procedures
The lunar landing procedure required precise planning and execution to ensure a safe and successful landing. It can be divided into several distinct phases:
Orbit Insertion
The spacecraft would first enter a circular orbit around the Moon, typically at an altitude of 100-120 km (62-75 miles).
Powered Descent Initiation
The lunar module (LM) would separate from the command module and begin its powered descent towards the lunar surface.
Descent to the Landing Site
The LM would use its descent engines to gradually reduce its altitude and velocity as it approached the landing site.
Hovering and Site Selection
Once the LM reached a low altitude, typically around 100 meters (328 feet) above the surface, it would hover and its crew would visually inspect the landing site for any potential hazards.
Touchdown and Lunar Surface Operations
The LM would then gently touch down on the lunar surface. The crew would conduct lunar surface operations, including deploying scientific instruments, collecting samples, and performing experiments.
Surface Explorations
Numerous surface exploration missions have been conducted on the Moon, providing valuable scientific data and insights. Neil Armstrong and Buzz Aldrin made history in 1969 by becoming the first humans to walk on the lunar surface during the Apollo 11 mission.
