How many days did Sunita Williams stay at space?
She spent 322 days in space in total, on two separate trips. For the first, she spent 195 days, which is the record for a female astronaut. For the other she spent 127 days. She has done 7 spacewalks, also a record for a female astronaut, totalling 50 hours and 40 minutes.
Does the human body have to decompress after reentry into Earth from space?
Typically, the atmosphere in spacecraft is kept close to what it is at sea level on earth, so no compression/decompression is required. Many spacesuit designs use a lower pressure, and spacewalkers "pre-breathe" 100% oxygen for several hours when preparing for spacewalks in order to prevent issues such as "the bends".
Do astronauts eat and drink during their space walks?
They eat while inside the space station or shuttle. Bars used to be positioned inside the spacesuit where the astronaut could take a bite at will, but they are no longer used as astronauts preferred to eat later. They do however have a drink bag and tube from which they can suck water. Spacewalks last up to seven hours and astronauts work hard during this time, so it is essential that they drink.
What are the features of the iss?
The International Space Station is a large spacecraft in orbit around Earth. It serves as a home where crews of astronauts and cosmonauts live. The space station is also a unique science laboratory. Several nations worked together to build and use the space station. The space station is made of parts that were assembled in space by astronauts. It orbits Earth at an average altitude of 220 miles. It travels at 17,500 mph. This means it orbits Earth every 90 minutes. NASA is using the space station to learn more about living and working in space. These lessons will make it possible to send humans farther into space than ever before.The space station has the volume of a five-bedroom house or two Boeing 747 jetliners. It is able to support a crew of six people, plus visitors. On Earth, the space station would weigh almost a million pounds. Measured from the edges of its solar arrays, the station covers the area of a football field including the end zones.In addition to the laboratories where astronauts conduct science research, the space station has many other parts. The first Russian modules included basic systems needed for the space station to function. They also provided living areas for crew members. Modules called "nodes" connect parts of the station to each other.Stretching out to the sides of the space station are the solar arrays. These arrays collect energy from the sun to provide electrical power. The arrays are connected to the station with a long truss. On the truss are radiators that control the space station's temperature.Robotic arms are mounted outside the space station. The robot arms were used to help build the space station. Those arms also can move astronauts around when they go on spacewalks outside. Other arms operate science experiments.Astronauts can go on spacewalks through airlocks that open to the outside. Docking ports allow other spacecraft to connect to the space station. New crews and visitors arrive through the ports. Astronauts fly to the space station on the Russian Soyuz. Robotic spacecraft use the docking ports to deliver supplies.Hope This Helped.
What was the Gemini Spaceship like?
The Gemini program was planned as a bridge between the first US manned space program (Project Mercury) and the much larger and challenging moon program (Apollo). President John F Kennedy promised to land Americans on the moon by 31st December 1969 after the May 1961 flight of Alan B Shepard which lasted just 15 minutes on Freedom 7, the first Mercury flight. Mercury was only meant to get an American astronaut into orbit and ensure the US had equal status with the USSR who had sent Yuri Gagarin aloft as the first human in space. The challenge of going to the moon was much much larger than the challenge of Mercury, and the Apollo program was not ready when Mercury ended in 1963. Gemini was designed to practice techniques needed for Apollo such as EVA (spacewalks), navigation software, long-endurance spaceflights, rendezvous, docking and equipment testing. Gemini was essentially an enlarged and upgraded Mercury spacecraft, able to carry two astronauts and perform much more sophisticated manouveres while in orbit. It was used between 1965 and 1966 for twelve flights.
Astronauts on spacewalks outside the orbiting Space Station have to wear protective clothing against which type of radiation?
you are thinking of Solar radiation. or radiation from the sun in simple terms.
What would an astronaut need to wear on Pluto?
An astronaut landing on Pluto would need to wear a spacesuit that is not much different from those used now for spacewalks in orbit of Earth.
Why are spacewalks repeated on every mission?
Every spacewalk (EVA) has a different purpose. Some of them are to attach new parts to the International Space Station and some are to repair it. Some of them are to repair the Hubbble Space Telescope.
What is the importance of walking in space?
Most "spacewalks" are done to repair or deploy instruments outside the shuttle or other craft. Most satellites and other space equipment is too large to work on in an enclosed ship (even the substantially large shuttle cargo bay). Spacewalks are often called EVA's (Extra-Vehicular Activities), and the only protection the astronaut has is his (or her) spacesuit. Not only are they cumbersome to work in, but the suits are comparatively fragile and could endanger the user if they leaked or malfunctioned. Most spacewalks are done while tethered to a spacecraft or station, but some use a portable thruster. In 1984, NASA tested a portable jetpack called an MMU (Manned Manuevering Unit), which let the astronaut jet around, moving only a discreet distance from the vehicle. For most of the activities, the astronauts are still hooked up with a safety line.
What are the advantages and disadvantages for dextre?
The Dextre reduces the number of spacewalks astronauts do. This increases the amount of time the astronauts have to research space and astronomy. The Dextre also will become space trash eventually once we have invented new technology.
What is the name of the space shuttle that made the first on orbit service of the Hubble space telescope?
The Space Shuttle Endeavor . December 2, 1993 it carried a crew of seven astronauts into orbit for a mission that would involve five days of spacewalks and repairs .
How do astronauts survive in space where their is not gravity and no oxygen?
They have oxygen. And they float. Unlike your brain.

What made Bruce McCandless famous?
Bruce McCandless (1937-2017) was a Space Shuttle astronaut who performed two of the first untethered spacewalks (EVAs) using the MMU, in 1984. He was on the Shuttle flight that launched the Hubble Space Telescope in 1990. A Naval aviator, he graduated from the Naval Academy in the same class (1958) as John McCain.

How do they repare the hubble space telescope?
They send men up who go on several several spacewalks to tediously repair the instruments manually. If they were repairing the Hubble on Earth, it would be fairly straightforward. But in space it is much more difficult and dangerous. Most of the time spent is preparation done on Earth. The new instruments are built and the astronauts do many many practise runs before the real thing. Once they're up in orbit, the mission takes several days and several spacewalks. The team are always in communication with ground control so that every detail is checked and any problems that come up can be reported and figured out back on the ground. After everything is finished, the instruments are checked to ensure they're working before the mission is complete. A few months later, the refurbished telescope is ready to observe the universe once again, with more powerful cameras installed. You can read about the STS-125 mission on Nasa's website, it was a fascinating one!
