During the Apollo 13 mission, the LM environmental control system provided a habitable environment for about 83 hours (57:45 to 141:05 GET). Cabin temperature remained low due to low electrical power levels. This caused crew discomfort during much of this period, with cabin temperatures ranging between 49°F and 55 °F.
“The spacecraft cabin temperature on a normal mission is controlled by using heat produced by electrical systems, with the excess heat dissipating by radiation into space. With the electrical systems turned off, the temperature approached about 34 degrees Fahrenheit prior to entering the atmosphere.
? To conserve energy the electrical systems were turned off for long periods of the journey. This meant that the spacecraft lost an important source of heat. The temperature dropped to three degrees Celsius, which was so cold that it was almost impossible to sleep.
This heat makes the Shuttle's surfaces reach temperatures of up to 1477° C (2691° F). We must design the re-entry trajectory, and the vehicle, to withstand these high temperatures.
With all that equipment shut down to conserve electrical power, the spacecraft was radiating heat faster than the astronauts produced it.
Due to a shallower re-entry path, Apollo 13's blackout was calculated to last about 4.5 minutes. Flight director Gene Kranz's logs show that it took about 6 minutes to re-establish contact with Apollo 13. Telemetry was usually the first signal received after the blackout.

You're inside the air that's being ripped apart as you're re-entering the atmosphere. Very little feeling, no shaking, no vibration, but you just see the heat that's being generated by the space shuttle entering the atmosphere.
During re-entry, the shuttle is going so fast, it compresses the air ahead of it. The compression of the air layers near the leading edges of the shuttle is quick, causing the temperature of the air to rise to as high as 3000 degrees Fahrenheit!
“The Shuttle used ceramic tiles to reradiate heat outwards, with a layer of insulation between the tiles and the vehicle,” says Anderson. The two principle factors that ensure a spacecraft can safely traverse the reentry corridor are the shape of the vehicle and its angle of reentry.
The highest temperature that scientists have created — and thus measured — is 2 trillion kelvins.
We were operating in a near perfect vacuum with the temperature well above 200 degrees Fahrenheit with the local gravity only one sixth that of Earth.
Thankfully, as it turned out ,the heat shield wasn't damaged. But almost miraculously, Woodfill said, the command module and service module remained connected following the explosion, while the internal pressure of the explosion rocketed the exterior panel into space.
The astronauts and mission control were faced with enormous logistical problems in stabilizing the spacecraft and its oxygen supply, as well as running on batteries due to the loss of the fuel cells to allow successful reentry into Earth's atmosphere.
As the Apollo 13 crew re-entered the Earth's atmosphere there was a blackout period where they couldn't communicate with mission control. The blackout period was supposed to last three minutes, but it lasted 90 seconds longer, leaving those at mission control unaware if the crew were going to make it home safely.
The command module was dying, quickly. But the lunar lander, docked to the command module, was intact. Under the direction of Glynn Lunney, the flight director whose shift followed Mr. Kranz's, the Apollo 13 astronauts scrambled into the lunar module, which served as their lifeboat.
In space, sweat evaporates more slowly than on Earth, which explains why astronauts were found to overheat particularly quickly during exercise tests performed on the ISS. Excessive fluctuations in core body temperature can impair both physical and cognitive performance, and can even be life-threatening.
The suit is equipped to regulate an astronaut's temperature as he or she endures the extreme heat of 250 degrees Fahrenheit in the Sun and -250 degrees Fahrenheit in the shadows. The suit must also be able to regulate the air inside to make sure the astronaut can breathe.
In space, there is no gravity to pull things straight down, so the gas and liquids in the astronauts' stomachs don't seperate. This means the gas can't come back up to create a burp! Or, at least, a burp like we would known on Earth.
Re-entry is a technologically challenging thing to survive, and even the smallest problem can escalate quickly, as the Columbia disaster taught us only too well. The main source of the problems with re-entry is that if you're orbiting the earth, you're going extremely fast.
The human body is designed to work in Earth's gravity, which means that when astronauts return to Earth, their bodies have to readjust to the planet's gravitational force. Astronauts may experience a reduced sense of balance, mobility, and coordination after landing on earth.
It's normal for astronauts to feel dizzy or faint when they come back to Earth. It's similar to what happens to people on Earth when they stand up quickly after sitting or lying down. The blood rushes away from the brain and your blood pressure drops temporarily.
An curved arrow pointing right. There was no bathroom on the Apollo missions. Instead, NASA astronauts peed into a roll-on cuff, and pooped in bags that they kneaded, rolled up tight, and took back to Earth.
Book Details. The bold story of Katherine Johnson, an African-American mathematician who worked for NASA during the space race and was depicted in the film Hidden Figures. You've likely heard of the historic Apollo 13 moon landing.
A vomit-shaped one to be exact. While chatting with EW about some of his most memorable roles, Kevin Bacon revealed that he ended up in the splash zone of a nauseous cameraman while making Ron Howard's Apollo 13.
