Did the shuttle columbia's astronauts survive?
no, all the astronauts on the final mission of columbia died during reentry.
Who was the first astronaut to test the mmu?
Bruce McCandless was the first astronaut to test the MMU (Manned Maneouvering Unit) during the STS-10 mission.
First lady astronaut wore FLATS?
FLATS had nothing to do with what the women wore. It stood for First Lady Astronaut Trainees. The FLATs were a group of women who applied for astronaut training during the days of the Mercury space program. None of them were ever selected.
Why do sky appears red during sun set?
This is because the light is travelling horizontally through the atmosphere, so we see it through a longer distance of air. The atmosphere and the dust it contains tend to scatter and absorb light at the blue end of the spectrum, leaving more red. This is why volcanic eruptions can cause even redder sunsets globally.
Did the first astronauts have space suits?
Yes, a pressure suit (otherwise known as a space suit) is a fundamental safety feature used on almost all space flights. The Soviets sent a few people up without one, but the United States requires that all its astronauts wear their pressure suit, including their helmet, during launch and reentry. The only U.S. crew that did not wear their helmets during reentry was the Apollo 7 crew. All 3 of them contracted severe head colds while in space. They felt their eardrums might burst due to sinus pressure if they had their helmets on during reentry. NASA administrators did not agree. None of the Apollo 7 astronauts ever flew again
What is the first layer of the atmosphere that an astronaut passes through during reentry from space?
The last layer of the atmosphere is called the thermosphere. They vary outer edge of the thermosphere is an area called the ionosphere.
Why would the nose encounter more intense heat than other parts of the shuttle during reentry?
The nose of the shuttle encounters more intense heat then the rest of the shuttle during reentry because of the friction it encounters from the atmosphere. The nose of the shuttle has a small surface area for the with weight of the shuttle pushing it through the atmosphere. This leads to a more focus point of contract with the atmosphere.
How hot does a space shuttle get when re-enters earths atmosphere?
The leading edges of the Space Shuttle's wings get to almost 3000 deg F during a normal reentry into earth's atmosphere.
What has the author Jerome H Fine written?
Jerome H. Fine has written: 'An attitude control system to constrain the skin temperature of a manned lifting spacecraft during reentry into the earth's atmosphere' -- subject(s): Attitude control, Spacecraft reentry
Why are spaceship provided with heat shield?
Spaceships are provided with heat shields to protect them during exit and reentry of the earth's atmosphere. If they didn't have these shields, the ship would burn up.
Where did the astronauts stay during launch and reentry in Apollo?
The astronauts stayed in the command module during launch and reentyry to earth. As it has a tiles that prevent the craft from over heating during reentry.
What was the space shuttle's speed during reentry?
As the shuttle reaches entry interface, the point where it starts to feel the effects of the atmosphere, it is traveling at about Mach 24.5 or about 24,000 miles per hour.
Why did the Columbia shuttle crash in 2003?
When an object moves through the air very, very fast the air pressing on the object gets extremely hot (thousands of degrees). This happens to the Shuttle when it reenters the Earth's atmosphere at the end of every mission. There are panels on the Shuttle that protect it from this heat during reentry. When Colombia was launched a piece of insulating foam on the big orange fuel tank came off and hit the wing of the Shuttle (the Orbiter) making a hole in these protective panels. Later, during reentry, this let the hot gasses generated during reentry to get inside the wing. This began a set of cascading failures that resulted in the Shuttle dissentigrating -- breaking up. It did not crash, it dissentirated in the air.
Did it explode during launch or reentry?
Challenger exploded during launch; Columbiaexploded during re-entry.
Does the space shuttle reuse the liguid-fuel tanks?
No. The large orange External Tank or ET as it is called is jettisoned at about the 8 minute mark of the flight and burns up in the earths atmosphere during its reentry.
How many space shuttles exploded in atmosphere?
Technically Challenger was the only shuttle to explode in the atmosphere during takeoff. It was caused by a leaky O ring in the Solid Rocket Boosters. Columbia broke up during reentry and therefore was not an explosion. It was caused by damaged heat Tiles that allowed heated gases to weaken the wing. Once the wing became weakened it gave way and caused the shuttle to tumble and at the speeds and heat involved in reentry the pieces burned up as it broke apart.
Why do spaceships are provided with heat shield?
The tiles are ceramics which is a metal skin from fluid friction.
