According to George Mueller, who was associate administrator of NASA's Office of Manned Space FlightHuman spaceflight (also referred to as manned spaceflight or crewed spaceflight) is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew.https://en.wikipedia.org › Human_spaceflight
After a midcourse correction, and command and service module separation, Apollo 10 re-entered Earth's atmosphere May 26. The module splashed down 165 degrees west, and 5 degrees, 8 minutes south in the Pacific Ocean. It's landing was within television range of its primary recovery ship, the USS Princeton.
Apollo 13 was NASA's third moon-landing mission, but the astronauts never made it to the lunar surface. During the mission's dramatic series of events, an oxygen tank explosion almost 56 hours into the flight forced the crew to abandon all thoughts of reaching the moon.
The lunar module lacked the capability to return the astronauts to Earth; this was the first time space travelers had flown in a vehicle that could not take them home.
With the world anxiously watching, Apollo 13, a U.S. lunar spacecraft that suffered a severe malfunction on its journey to the moon, safely returns to Earth on April 17, 1970.
The TLI placed Apollo on a "free-return trajectory" - often illustrated as a figure of eight shape. This course would have harnessed the power of the Moon's gravity to propel the spacecraft back to Earth without the need for more rocket fuel.
7, Apollo 15 splashed down in the Pacific Ocean, about 335 miles north of Honolulu, ending a flight of 12 days, seven hours. The crew was picked up by helicopters from the prime recovery ship, the USS Okinawa, 6.32 miles from the targeted touchdown point.
They might have wanted to, but it was impossible for that lunar module to land. It was an early design that was too heavy for a lunar landing, or, to be more precise, too heavy to be able to complete the ascent back to the command module.
Images taken by the Lunar Reconnaissance Orbiter (LRO) have shown that the American flags left on the Moon by Apollo astronauts are still standing– except for the Apollo 11 mission, which Buzz Aldrin reported as being knocked over by engine exhaust as Apollo 11 lifted off.
Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.
Although the historic Apollo 11 mission's three astronauts made it home safe, a once-classified anomaly almost killed them. The problem occurred during Apollo 11's return to Earth. It caused a discarded space module to nearly crash into the crew's capsule.
The Apollo 13 malfunction was caused by an explosion and rupture of oxygen tank no. 2 in the service module. The explosion ruptured a line or damaged a valve in the no. 1 oxygen tank, causing it to lose oxygen rapidly.
An explosion 56 hours into the mission happened before the command module and lunar module had separated, so the crew were able to use the intact lunar module as a lifeboat with its own power sources, rockets and oxygen supply.
On July 20, Armstrong and Aldrin landed on the Moon, and four days later the three astronauts returned to Earth, fulfilling John F. Kennedy's challenge to Americans to land astronauts on the Moon and return them safely to Earth by the end of the 1960s.
Does anyone know why Apollo 10 recorded the fastest speed? Primarily the result of the (lunar) orbital altitude upon initiation of the TEI burn coupled with burn duration. Note that the difference in velocities between the returning spacecraft was quite small (less then a fraction of one percent).
Cernan made the trip. Stafford is the only surviving member of the crew. The procedures tested during Apollo 10 showed NASA that a lunar landing really was possible and what issues might arise during its successor's touchdown.
Yes, the flag is still on the moon, but you can't see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
The flag is no longer standing. In fact, it's been flat on the ground since the moment Aldrin and Neil Armstrong lifted off. As the Eagle module ignited its engines and rose, spewing exhaust around, Aldrin caught a glimpse of the flag falling from his window. The flag, made of nylon, was an off-the-shelf purchase.
The very first nation to reach the surface of the moon was the USSR (Russia), whose unmanned spacecraft Luna 2 impacted the moon' surface on 12 September 1959. While Luna 2 was the first probe to land on the moon, it had been designed to crash-land into the surface (a "hard landing") rather than conduct a soft landing.
Snoopy's trajectory was unique among the Apollo missions. Unlike in the five missions that landed on the Moon, the Snoopy lunar module was ultimately jettisoned into an orbit around the Sun.
Just 18 hours after launch, Apollo 8 experienced a major problem: Borman fell ill and struggled through vomiting and diarrhea. The commander felt better after getting some sleep, but as a precaution, the other crewmembers radioed to Earth on a private channel and explained Borman's predicament.
Is the Apollo 10 1/2 mission real? To simply put it, no. The mission is a fictitious creation in Stan's mind. The reimagining of the mission to the moon through a kid's eyes fascinated with how the space journey worked is a better way of explaining the events of the film.
The command module of Apollo 13 entered Earth's atmosphere and splashed down on target on April 17 at 1:07 PM Eastern Standard Time. The mission has been referred to as a successful failure, in that all the crew members survived a catastrophic accident.
Mattingly had been scheduled to fly on the Apollo 13 mission, but three days prior to launch, he was held back and replaced by Jack Swigert due to exposure to German measles (which Mattingly did not contract).
Less than two years earlier, on Jan. 27, 1967, the three crew members of Apollo 1 — Virgil I. Grissom, Edward H. White II and Roger B. Chaffee — were killed in a fire on the launchpad during a preflight test at Cape Kennedy, Fla.
