Is it true that the EECOM referred back to the simulation that they failed before the mission in order to help get Apollo 13 home?

NO!! EECOM is an acronym for "Electrical, Environmental Consumables Manager. In the case of Apollo 13, that would be Sy Liebergot. The EECOM is one of the controllers in Mission Control who feed mission critical information to the Flight Director, who is in charge of the mission. In the case of Apollo 13, the EECOM was critical in the successful return of the crew. He was able to stretch 2 days worth of oxygen and 2 hours worth of battery power into 4 days.

Who were the first ten astronauts to land in moon?

There have been 12 men to land and walk on the moon.

In order:

1: Neil Armstrong

2: Buzz Aldrin

3: Pete Conrad

4: Alan Bean

5: Alan Shepard

6: Edgar Mitchell

7: Dave Scott

8: Jim Irwin

9: John Young

10: Charlie Duke

11: Gene Cernan

12: Harrison Schmitt

Armstrong and Aldrin were from Apollo 11, Conrad and Bean from Apollo 12, Shepard and Mitchell from Apollo 14, Scott and Irwin from Apollo 15, Young and Duke were on Apollo 16 and Cernan and Schmitt were Apollo 17.

So to answer your question, the first 10 on the list were the first 10 people to land on the moon.

Is Apollo 16 a lander?

Apollo 16 was a manned mission to the moon in 1972, but it was not a lander. The mission included a lunar module that landed on the moon, which was used to explore the lunar surface by the astronauts.

Why is Apollo 8 called Apollo 8?

Very simple - it was the next mission in the series after Apollo 7.

One of the crew members - James Lovell - drew a sketch from which the mission patch was made. It showed the path of the spacecraft, going off to the Moon and returning to Earth describing a figure of 8. Lovell knew that the actual flight path wouldn't be an exact figure of 8, but it was descriptive of the aim of the mission - to fly to the Moon and return - and was a very visual way of including the mission number.

How fast did Apollo 11 travel to the moon?

Let me clarify Stu's answer below. When the Apollo spacecraft left earth's orbit they executed what they referred to as a TLI burn (Trans-Lunar Injection). This burn accelerated the spacecraft from an earth orbital velocity of approximately 17,500 mph to the TLI velocity of about 25,000 mph. The engines were then cut off, and the spacecraft "coasted" to the point where the earth's gravitational pull was equaled by that of the moon. At this point, the spacecraft had slowed due to the continuing (albeit decreasing) pull of earth's gravity to a mere 2,000 mph. At that "tipping point" the moon's gravity took over and began accelerating the spacecraft again until it reached the vicinity of the moon, at which point it's speed was around 5,000 mph. At that time the spacecraft executed an LOI (Lunar Orbit Insertion) retro-burn designed to slow it to a velocity which would place it in a specific orbit around the moon, approximately 3,600 mph.

Stu:

At the time when Apollo 11 left Earth orbit for the Moon, it was traveling at approximately 36,700 ft./sec. Its velocity was slowed all the way to the Moon, by the Earth's gravity. On the return journey, the Earth's gravity accelerated the Command Module, so that just before it hit the Earth's atmosphere, it was traveling approximately 36,300 ft./sec. There was nothing special about Apollo 11's velocity; any vehicle traveling to the Moon, manned or unmanned, would have to achieve the same velocities.

I'm assuming that you knew that 9 Apollo missions went to at least lunar orbit, and that 6 Apollo Lunar Modules actually made landings.

How big was the lunar module?

The lunar module used during the Apollo missions was about 23 feet tall and 31 feet wide. The ascent stage, where the astronauts sat, was around 10 feet high and 14 feet wide.

Which of the moon-formation theories was supported by the findings of the Apollo missions?

The giant impact hypothesis was supported by the findings of the Apollo missions. This theory suggests that the Moon formed from debris created when Earth collided with a Mars-sized body early in the history of the solar system. The composition of Moon rocks collected by Apollo astronauts closely matched that of Earth's crust, providing evidence for this theory.

What did the first spaceman saw on the moon?

The first astronaut to walk on the moon was Neil Armstrong during the Apollo 11 mission in 1969. He described the surface as powdery and covered in small craters. The iconic phrase he said was, "That's one small step for man, one giant leap for mankind."

Why is there no stars in the moon landing pictures?

It is simple as they wee walking in the day time you see.

To understand this, you need to know a little about how cameras work. When the shutter release on a camera is pressed, the shutter opens for a fraction of a second, allowing the light-sensitive material behind the shutter to be exposed. The amount of light that is allowed through is controlled both by how wide the shutter opens (aperture) and for how long it's open (shutter speed). The brighter the object being photographed the less light you want to let through to the film. Too much exposure will create an unrecognizable photograph; you will simply see a white blob. This is critical to understand because it is at the heart of the "missing" stars.

The surface of the moon, in direct sunlight (as it was during the Apollo missions), is very bright. So bright, in fact, that it can create shadows on the Earth in the middle of the night from 238,000 miles away. That fact alone means any camera used on the moon's surface must have the settings as such to no overexpose the film. But the astronauts weren't just taking pictures of the moon; they also took pictures of each other. The cameras used by the crew were set up to take pictures of the lunar surface, other astronauts in white spacesuits, in a bright white environment, in the middle of the lunar morning, in direct sunlight. The fact that no stars showed up in the images is to be expected. Had there been stars there would have been more evidence of a hoax.

Who were the astronauts on Apollo 14?

The astronauts who flew the Apollo 14 mission were Commander Alan Shepard, Command Module Pilot Stuart Roosa, and Lunar Module Pilot Edgar Mitchell. The astronauts of the backup crew were Commander Eugene A. Cernan, Command Module Pilot Ronald E. Evans, Jr. and Lunar Module Pilot Joseph H. Engle.

Why no more moon landings since 1972?

There are a few reasons why there have been no more moon landings since 1972. One major reason is the high cost associated with manned missions to the moon, making them less of a priority compared to other space exploration endeavors. Additionally, focus has been shifted towards exploring other celestial bodies, such as Mars, and advancing technology that can aid in future lunar missions.

How many people have just landed on the Moon and not walked on it?

None. All 12 astronauts that landed there got out and walked around, mostly picking up rocks.

There were 9 manned missions that reached lunar orbit: Apollo 8, 10, 11, 12, 13, 14, 15, 16, and 17.

Apollo 8 just orbited, Apollo 10 just tested the Lunar Lander in lunar orbit (dress rehearsal), and Apollo 13 had a severe malfunction that meant they could not land on the Moon. The other six missions landed 2 astronauts each.

Where did the first astronauts who landed on the moon presented the rocks that they collected from the moon?

In September of 1969 the first public exhibition was opened in the Smithsonian Institution in Washington. Thousands lined up to get a glimpse of a moon rock, but many found it disappointingly ordinary.

Where abouts on the moon did Neil Armstrong land?

Neil Armstrong landed in the southern portion of the moon's Sea of Tranquility, specifically at a site known as "Tranquility Base."

How many astronauts have been to the moon since 1969?

Only 12 men have walked on the moon since 1969, the last man stepping foot in December of 1972.

When did Apollo 17 land?

Apollo 17 landed on the moon on December 11 1972 at 19:54:57 UTC.

When did Apollo11 astronauts took their walk on the moon?

The Apollo 11 astronauts, Neil Armstrong and Edwin "Buzz" Aldrin, took their historic moonwalk on July 20, 1969. Neil Armstrong was the first person to set foot on the lunar surface, followed by Buzz Aldrin.

Have there been other manned flights to the Moon or beyond Earth orbit prior to Apollo 8 or after Apollo 17?

No, Apollo 8 was the first manned mission to orbit the Moon, and Apollo 17 was the last manned mission to the Moon. No other manned missions have been to the Moon or beyond Earth orbit before or after those missions.

When did the Apollo 1 program start?

Apollo 1 wasn't a program, it was a mission scheduled to launch in February, 1967. However, the capsule caught fire on January 28, 1967 and killed the crew.

The first Apollo launched on October 11, 1968.

Apollo actually started during the Kennedy administration as a means of achieving his goal of "Landing a man on the moon in this decade and returning him safely to the earth."

How many other American astronauts walked on the moon after armstorng and Aldrin?

Ten other American astronauts have walked on the moon after Neil Armstrong and Buzz Aldrin. These astronauts were part of the Apollo missions that followed Apollo 11, specifically Apollo 12, 14, 15, 16, and 17.

Can you see the lunar lander on the moon?

No, the lunar landers left on the Moon during the Apollo missions cannot be seen from Earth without powerful telescopes. The size of the landers is small relative to the vastness of the lunar surface, making them difficult to spot.

What Apollo missions didn't have to do with the moon?

Apollo 7, Apollo 9, and Apollo 10 did not land on the moon. Apollo 7 was the first crewed mission in the program, testing the spacecraft in Earth orbit. Apollo 9 tested lunar module systems in Earth orbit. Apollo 10 performed a dress rehearsal for the moon landing, orbiting the moon but not landing.
