Challenger and Columbia Disasters

Christa McAuliffe was the school teacher astronaut who was killed in the Challenger shuttle explosion in 1986. She was selected from thousands of applicants to be the first civilian in space as part of NASA's Teacher in Space Project.

The space shuttle Challenger exploded on January 28, 1986, 73 seconds after liftoff, resulting in the tragic loss of all seven crew members onboard. The cause of the explosion was determined to be a failed O-ring seal in one of the solid rocket boosters.

There were a total of 17 Apollo missions, including both crewed missions and uncrewed test flights. Eleven of these missions landed astronauts on the Moon, while the rest were Earth orbit missions or test flights.

The seven astronauts who lost their lives on the space shuttle Challenger on January 28, 1986, were Francis R. Scobee, Michael J. Smith, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis, and Christa McAuliffe.

The Space Shuttle Columbia did not actually blow up. Rather, it was torn apart and disintigrated. The Columbia disaster was caused as a result of foam on the space shuttle's external fuel tank (ET). The ET is covered in insulating foam to prevent ice from forming from the cold liquid oxygen and liquid hydrogen propellants. During launch, aerodynamic forces pulled a large piece of the foam off of the ET, and it impacted some of the space shuttle's Reinforced Carbon-Carbon (RCC) panels on the left wing, causing a hole. The RCC panels are used to protect the space shuttle from the violent heat of re-entry. However the hole allowed hot gases to melt the inside of the shuttle's wing, which destroyed it structurally. As Columbia's structure melted and fell apart, aerodynamic forces broke up the vehicle into hundreds of thousands of pieces, killing the crew.

The first manned rocket was launched in 1961

The Columbia shuttle was launched using the Space Shuttle system, which involved strapping the shuttle onto a rocket boosters and an external fuel tank. The boosters provided most of the thrust during liftoff, with the shuttle's main engines igniting once in space.

As the vehicle cleared the tower, the SSMEs were operating at 104% of their rated maximum thrust, and control switched from the Launch Control Center (LCC) at Kennedy to the Mission Control Center (MCC) at Johnson Space Center in Houston, Texas. The shuttle was scattered over the Atlantic within seconds of taking off from Kennedy.

NASA's Apollo Program lasted from 1963-1972. In which time it held 15 missions of different objectives. Including Apollo 11 consisting of Neil Armstong, Buzz Aldrin, and Michael Collins

The astronauts killed in the Apollo 1 spacecraft fire on January 27, 1967, were Gus Grissom, Ed White, and Roger B. Chaffee.

The Challenger exploded because the primary and secondary O-rings were stiff from cold weather. They were not put in correctly and not checked. Hot gases leaked thorugh the O-rings and mixed with the fire from take off. The external tank then caught on fire and soon the Challenger exploded, killing the seven passengers including Christa McAuliffe.

Columbia didn't explode at lift off. I think you're mistaking it for Challenger, which exploded early in it's flight. Columbia broke apart as it was re-entering the atmosphere. there was a piece of foam that broke off early in the flight (within the first 90 seconds I believe they said) and it doomed the shuttle. the Year it xpolded was 2003 it exploded at lift off 7 people died the Year it xpolded was 2003 it exploded at lift off 7 people died

The cost for a shuttle mission can vary significantly depending on the specific requirements and complexities of the mission. On average, the cost of a space shuttle mission was estimated to be around $450 million. However, with the retirement of the space shuttle program, new commercial solutions for space transportation have emerged, offering a wider range of pricing options.

The first space shuttle disaster was the explosion of the space shuttle Challenger on January 28, 1986. The shuttle broke apart 73 seconds after launch, resulting in the tragic loss of all seven crew members on board.

The intended purpose of the Columbia STS-107 space shuttle mission was to conduct a variety of scientific experiments in fields such as astronaut health, fluid physics, and material sciences in microgravity. The mission aimed to advance our understanding of these areas and their applications on Earth.

There was a small flame on the ET (External Tank) Space Shuttle Challenger was so high into the sky at that time that mission control could not see it. They continued for throttle up which releases more power to help Challenger get through the atmosphere. Dick Scobee said: "Roger. Go for throttle up." That was the last that was heard. My guess is the ET, which contains very flammable liquids, caught on fire. It burned the shuttle and everyone in it. No one can be certain because the last words were confirming throttle up. Then nothing. Hope this helps!

That is not quite what happened, though that makes sense from looking at the video.

To answer the original question, there is evidence that would indicate the astronauts died after falling from 9 miles up. The oxygen levels in their tanks indicate that they were alive for a long time after the explosion.

The explosion was due to on O-ring problem that engineers had been telling management about since 1977 (9 years prior to launch). The day before the launch, there were 4 engineers basically screaming at management to not launch, but they did anyway. The two main factors contributing to the failure were flawed design and cold temperature (they launched on a day that was 19 degrees F colder than the engineers had specified).

Liftoff was at 11:38:00.010 Eastern Standard Time. The O-ring failure developed almost immediately, leading to the explosion and breaking apart of the shuttle 73 seconds into the flight.

A space shuttle is launched into space using powerful rockets. Once in space, it uses onboard thrusters to maneuver and adjust its course. The shuttle then re-enters the Earth's atmosphere and glides back to a landing site like a plane.

Life in space is a challenge for humans because you can't breathe like you do in earth as in space, you always eat dried food, and people who move in their sleep have to deal with being strapped to their bed.

The Canadarm is a renowned Canadian robotic arm used on the Space Shuttle program. After retiring in 2011, it was replaced by the Canadarm2 on the International Space Station. The original Canadarm is now displayed at the Canada Aviation and Space Museum in Ottawa.

Crew members of the International Space Station typically stay for about six months before returning to Earth and being replaced by new crew members. This allows for a consistent presence on the station while still providing opportunities for astronauts to rotate in and out regularly.

Physicist Richard Feynman was part of the committee that investigated the Space Shuttle Challenger disaster in 1986. He famously conducted an experiment where he demonstrated the O-ring seal's failure in cold temperature, which was identified as the cause of the explosion. His efforts played a significant role in understanding the technical and organizational failures that led to the accident.

The Columbia Space Shuttle broke apart upon re-entry into Earth's atmosphere on February 1, 2003, resulting in the tragic loss of all seven crew members on board. The accident was caused by damage to the shuttle's thermal protection system, which occurred during liftoff when a piece of foam insulation struck the shuttle's left wing.

The Columbia Space Shuttle explosion had a significant impact on the space program, leading to a 29-month suspension of the Space Shuttle program. It resulted in enhanced safety measures, changes in the shuttle's design, and a reevaluation of NASA's safety culture. The tragedy also highlighted the risks involved in space exploration and the importance of continuous learning and improvement in space missions.

The part of the spaceshuttle the crew from the challenger were sitting in landed in the ocean upon explosion and all 7 crew members were found inside dead.
