Does the speed of a satellite in orbit depend on its mass?
The speed of a satellite in circular orbit around a planet does not depend on the mass of the satellite.
Do astronauts wear heavy boots?
2. You’ve seen films of the APOLLO astronauts walking around on the Moon, why didn’t they fall off? About 20 percent of the people changed their answer to the first question when they heard this one! But the most amazing part was that about half of them confidently answered, “Because they were wearing heavy boots.”
What boots do astronauts wear?
Magnetic boots are boots that are magnetic, which allows them to attach to the ferrous floor or hulls of a spacecraft during weightlessness, and presumably would allow someone to walk around the cabin of a spacecraft, but they would still feel weightless.
What would happen if you dropped a pen on the moon?
The pen would float away probably toward the gravitational pull of the earth.” “[It will float where it is] Because there is no gravitational pull. It will neither fall towards the moon because there is no gravity to pull it there nor is there any other gravitational force that will pull it away from the moon.”
What type of shoes do astronauts wear?
Astronauts working aboard the Space Shuttle and International Space Station often wear slipper socks like these. Shoes are not necessary in weightlessness, but crewmembers enjoy the comfort and warmth of soft footwear.
Does skin come off in space?
On Earth, we barely notice that process: our skin cells molt and and gravity pulls them away from our bodies, conveniently and invisibly. In space, however, there is no gravity to pull the dead cells (technically: the detritus) away. “This cloud, this explosion of skin particles — detritus — floats out,” he says.
Do astronauts skin fall off?
“The calluses on your feet in space will eventually fall off,” he wrote. “After about two months in orbit your feet molt, and like some reptilian creature the callused skin on the bottom of your foot sheds, leaving soft pink flesh in its place,” he wrote.
Can your heel come off in space?
“The calluses on your feet in space will eventually fall off,” astronaut Scott Kelly revealed in a Reddit AMA. “So, the bottoms of your feet become very soft like newborn baby feet.
What happens to your skin when in space?
After about 10 seconds or so, your skin and the tissue underneath will begin to swell as the water in your body starts to vaporise in the absence of atmospheric pressure. If you do die in space, your body will not decompose in the normal way, since there is no oxygen.
Can your eyes pop out in space?
A closer look at space travelers revealed that a buildup of brain fluids may be squishing their eyeballs from behind. Many astronauts returning to Earth after long-duration missions in space suffer from blurry vision that does not always get better.
Do you lose vision in space?
“The problem is the longer the astronauts are in space, the more likely they are to experience visual impairment. Some astronauts will recover from vision changes, but some don’t. So this is a high priority for NASA and space agencies worldwide.
