An analysis of the mistakes that led to the failure of apollo 13 space mission

A mission where you bring along tons of scientific payload, and stay on Mars for 40 days to do some science. A mission with no payload just a Very Important Person.

Haise was rotated out of the crew and onto the backup crew of Apollo 11 as LMP. For Apollo, a third crew of astronauts was added, known as the support crew.

What's New

The support crew maintained the flight plan, checklists and mission ground rules, and ensured that the prime and backup crews were apprised of any changes. The support crew developed procedures in the simulators, especially those for emergency situations, so these were ready for when the prime and backup crews came to train in the simulators, allowing them to concentrate on practicing and mastering them.

The directors for Apollo 8 were Clifford E. It shows a red figure-8 looping around the Earth and Moon to reflect both the mission number and the circumlunar nature of the mission.

On the bottom of the 8 are the names of the three astronauts. Lovell reportedly sketched the initial design while riding in the backseat of a T flight from California to Houstonshortly after learning of the re-designation of the flight to become a lunar-orbital mission.

The graphic design of the insignia was done by Houston artist and animator William Bradley. Further missions depended on the readiness of the Lunar Module. That there would be at least four had been decided as early as May This would mean delaying the "D" and subsequent missions, and endangering the program's goal of a lunar landing before the end of Instead of just repeating the "C" mission flight of Apollo 7, this CSM could be sent all the way to the Moon, with the possibility of entering a lunar orbit.

The new mission would also allow NASA to test lunar landing procedures that would otherwise have to wait until Apollo 10the scheduled "F" mission.

This also meant that the medium Earth orbit "E" mission could be dispensed with. The net result was that only the "D" mission had to be delayed. PhillipsRocco Petrone and Wernher von Braun. Kraft considered the proposal feasible from a flight control standpoint; Debus and Petrone agreed that a Saturn V, AS, could be made ready by December 1; and von Braun was confident that the pogo oscillation problems that had afflicted Apollo 6 had been solved.

Almost every senior manager at NASA agreed with this new mission, citing both confidence in the hardware and personnel, and the potential for a significant morale boost provided by a circumlunar flight. The only person who needed some convincing was James E.

Webbthe NASA administrator. With the rest of his agency in support, Webb authorized the mission. Apollo 8 was officially changed from a "D" mission to a "C-Prime" lunar-orbit mission.

He turned it down; his crew had spent a great deal of time preparing to test the LM, and that was what he still wanted to do. Slayton then decided to swap the prime and backup crews of the D and E missions. Scott was not happy about giving up CM, in which he had carried out hours of tests for the unfamiliar CM, although the two were almost identical, and Anders was less than enthusiastic about being an LMP on a flight with no LM.

The total was a tenth of the amount that the Saturn V would burn every second. The next day, the Lindberghs watched the launch of Apollo 8 from a nearby dune. Apollo 6 had suffered several major problems during its April flight, including severe pogo oscillation during its first stage, two second stage engine failures, and a third stage that failed to reignite in orbit.

Without assurances that these problems had been rectified, NASA administrators could not justify risking a manned mission until additional unmanned test flights proved that the Saturn V was ready. Of primary concern was the pogo oscillation, which would not only hamper engine performance, but could exert significant g-forces on a crew.

A task force of contractors, NASA agency representatives, and MSFC researchers concluded that the engines vibrated at a frequency similar to the frequency at which the spacecraft itself vibrated, causing a resonance effect that induced oscillations in the rocket.

A system using helium gas to absorb some of these vibrations was installed. Researchers quickly determined that a leaking hydrogen fuel line ruptured when exposed to vacuum, causing a loss of fuel pressure in engine two.

When an automatic shutoff attempted to close the liquid hydrogen valve and shut down engine two, it accidentally shut down engine three's liquid oxygen due to a miswired connection. As a result, engine three failed within one second of engine two's shutdown.

Further investigation revealed the same problem for the third-stage engine—a faulty igniter line. The team modified the igniter lines and fuel conduits, hoping to avoid similar problems on future launches. A Saturn stage IC was equipped with shock absorbing devices to demonstrate the team's solution to the problem of pogo oscillation, while a Saturn Stage II was retrofitted with modified fuel lines to demonstrate their resistance to leaks and ruptures in vacuum conditions.

Once NASA administrators were convinced that the problems were solved, they gave their approval for a manned mission using SA Final testing of modifications to address the problems of pogo oscillation, ruptured fuel lines, and bad igniter lines took place on December 18, a mere three days before the scheduled launch.
