How do you make a spaceshuttle?

Making a space shuttle involves designing and building a complex vehicle that can withstand the extreme conditions of space and re-entry into Earth's atmosphere. The process includes engineering the structure, propulsion systems, thermal protection, and life support systems to ensure the safety of astronauts traveling to and from space. It requires advanced technology, materials, and expertise in spacecraft design and manufacturing.

How long is a typical Shuttle mission?

Typically a space shuttle mission lasts about a week, although a mission can last up to 10 days. However with the extended duration orbiter (EDO) pallet (A 15 ft diameter assembly of equipment) installed in the space shuttle's payload bay, a shuttle mission can last up to 16 days. The flaw with the EDO though is that it takes up weight and space in the shuttle's payload bay, meaning that the shuttle cannot carry as much cargo. A total of 14 space shuttle missions have used the EDO pallet, although it was destroyed by the Columbia accident on STS-107.

The longest space shuttle mission was STS-80, which lasted 17 days and 15 hours. The shortest were STS-1 and STS-2, each lasting 2 days and 6 hours.

Did apollo 13 explode in space?

A part on Apollo 13 - an oxygen tank in the command module - exploded, and seriously damaged the spacecraft. It took huge ingenuity and a good stroke of luck to get the astronauts back to Earth safely.

Why is life in space a challenge for humans?

Life in space presents challenges for humans due to factors such as microgravity, radiation exposure, isolation, and limited resources. Extended periods in space can lead to muscle atrophy, bone loss, and effects on the cardiovascular system. Additionally, the lack of gravity requires adjustments in everyday activities such as eating, sleeping, and exercise.

Why did the Columbia space shuttle explode?

The Space Shuttle Columbia disintegrated upon re-entry into Earth's atmosphere in 2003 due to damage to its thermal protection system caused by a piece of foam insulation that broke off from the external fuel tank during launch. This damage allowed hot atmospheric gases to penetrate the heat shield during re-entry, leading to the shuttle's breakup.

Why did the space shuttle challenger exploded?

Damaged seals on a joint in one of the solid rocket boosters made the booster separate from the rest of the vehicle causing a massive explosion.

Why did the space shuttle Columbia come to a disaster?

On blast off, a small piece of foam hit the wing, creating a small hole. On re-entry to the atmosphere the wing began to burn at that location due to hot gases getting in and a fire spread. This is what eventually destroyed Columbia.

How long did Challenger astronauts survive?

The Challenger astronauts survived for approximately 2 minutes and 45 seconds after the shuttle broke apart in mid-air on January 28, 1986. The crew did not survive the impact with the ocean.

What day of the week did the shuttle challenger explode?

The space shuttle Challenger exploded on January 28, 1986, which was a Tuesday.

Why was space challenger launched?

The Space Shuttle Challenger was launched as part of NASA's STS-51-L mission to deploy a communication satellite. However, the launch resulted in a tragic disaster as the shuttle exploded 73 seconds after liftoff on January 28, 1986, due to O-ring failure in one of the solid rocket boosters. This led to the loss of all seven crew members onboard.

What were the names of the seven astronauts who died in the first space shuttle accident?

They were:

  • Michael J. Smith - Pilot/astronaut. Was the last recorded voice to be heard from Challenger, saying "Uh-oh" which fits as he would have been one of the first people to become aware of the critical damage sustained when the shuttle's right SRB began to detach from the rest of the craft in the wind shear which would faciltate its destruction.
  • Lt. Col. Francis Richard "Dick" Scobee - Spacecraft Commander/astronaut. Scobee's last received telemetry transmission of: 'Roger, go at throttle up' would be the fateful action which would ultimately tear Challenger to pieces.
  • - Dr. Ronald Ervin McNair - Physicist/Astronaut. Also flew in the first Challenger mission, becoming the second African-American in space.
  • - Lt. Col Ellison Shoji Onizuka(promoted to Col. posthumously) - Research Engineer/Astronaut. Flew the first Discovery mission for the Department of Defense in 1985. A shuttle aboard the Enterprise in Star Trek: The Next Generation was named after him.
  • S. Christa McAuliffe - Teacher/Payload Specialist. Undoubtedly the most famous of all the crew; was the first civilan teacher selected for the 'Teacher In Space' program. Her death and the horror of the accident was made all the more acute due to the millions of schoolchildren eagerly watching the launch live on television and also due to the huge popularity and rapport she had gained with the media prior to the event.
  • Cpt. Gregory Bruce Jarvis - Payload Specialist/Engineer. Jarvis was discovered in the lower mid-deck along with McNair and McAuliffe when rescuers located the command module on the ocean floor - tragically, his body escaped from the wreckage, floated to the surface and was lost at sea. Fortunately, on the last scheduled attempt to recover wreckage on April 15th Captain Jarvis was relocated and returned to shore. He was posthumously awarded the Congressional Space Medal of Honour.
  • Judith Arlene Resnik - Engineer/Astronaut. Resnik had several accolades to her name: she was the second American woman, the first American/Jewish, the first Jewish woman and only the second Jew to go into space after Boris Volynov of the Soviet Union. Her first appearance in orbit aboard caused some notoriety as her long, dark hair ballooned around her head. Despite these differences she was, like McAuliffe, much loved by the media, having a playful sense of humour and a fine adaptability to space-flight.

What exat date did space shuttle Columbia explode?

There are many dates in history that should be remembered. The Columbia Space Shuttle Disaster happened on February 1, 2003.

What caused Space Shuttle Challenger to explode?

The Space Shuttle Challenger explosion on January 28, 1986 was caused by the failure of an O-ring seal in one of the solid rocket boosters, which allowed hot gases to escape and ignite the external fuel tank. This led to the disintegration of the shuttle. The O-ring failure was attributed to the cold weather on the day of launch, which compromised the seal's flexibility and effectiveness.

What caused the challenger to blow up?

The ground level temperature was 36 F. 15 F colder than any other launches. After 0.68 seconds, black smoke was coming from the AFT joint of the right rocket booster. Then seventy-two seconds after launch a chain of events caused the shuttle to explode. First, the lower strut connecting the right rocket booster to the external tank was extremely hot and weak. Second, the force that was on the strut made it break away from the right rocket booster and the external tank. Third, since the strut broke away from the right rocket booster, this allowed the right rocket booster to spin freely. With the right booster spinning freely, the bottom was burning, hitting, and denting the challengers' wing. The inside of the external tank had ruptured and was letting out liquid hydrogen. The top of the rocket was hitting the top of the external tank and also broke the oxygen tank. The vapor that these two chemicals made it very dangerous. The vapor is what made the main explosion. This explosion is what killed all six astronauts plus the one civilian.

What caused space shuttle the challenger to blow up?

The space shuttle Challenger exploded on January 28, 1986, due to the failure of an O-ring seal in one of the solid rocket boosters. The cold weather on the day of the launch compromised the O-ring's elasticity, leading to hot gas escaping and ultimately causing the catastrophic failure of the shuttle's external fuel tank.

How do space aircrafts works?

Space spacecrafts work by using rockets to propel them through the vacuum of space. They carry fuel to power the rockets and can adjust their trajectory using thrusters. Once in space, they rely on the laws of physics to continue moving in a straight line unless acted upon by another force.

How did the shuttle Challenger blow up?

The cold weather caused two of the O-rings in the right solid rocket booster to not seal properly, so hot gases escaped but left behind some aluminium that is in rocket fuel to cover up the hole. At 50 something seconds after liftoff there is a very strong wind that pushes it back and forth (that is also why the smoke cloud left behind is in a zig-zag), dislodging the aluminium and causing a fire, the fire then burned the connector between the rocket boosters and the fuel tank, dislodging the rocket booster. The booster then got hit by wind and made the booster hit into the fuel tank causing it to explode.

What year did the space shuttle blow up?

The space shuttle Challenger exploded on January 28, 1986, shortly after liftoff.

Real time applications of stack?

Stacks are commonly used in real-time applications such as backtracking algorithms, function call management in programming, and managing undo operations for applications like text editors or design software. They are also used in web browsers to manage history navigation and in expression evaluation in programming languages.

Which women have died in space missions?

On the space shuttle Challenger, teacher Christa McAuliffe, and Judith Resnik died in January 1986. In February 2003, Lauren B. Clark and Kalpana Chawla were killed during re-entry of the shuttle Columbia.

What was the name of the Russian space station launched in 1986?

Mir was launched in 1986, and remained in orbit until March 2001 when it burned up in the earth's atmosphere after it was intentionally de-orbited when its orbit became too low.

How has technology improved space travel?

With the advent and improvement of the technology systems, space travel and exploration have become more safe and apt. The data processing and transmission from space is more accurate now and it has better equipped man in his search of the unknown in the space.

Why was the canadarm made?
