The International Space Station (seen here in 2018) has been continuously occupied by astronauts since 2000. NASA Imagine you wake up in the morning, look out your window and see the vast blue horizon of Earth and the blackness of space. Our world stretches out beneath you. Mountains, lake...
Dennis Tito has become the world’s first “space tourist”. He went on a 10-day visit to the International Space Station. He paid 14 million pounds for his journey. A year later, Martin wanted to do the same. He was only 22 years old and probably very rich too. He is still ...
Who built the Challenger space shuttle? Where was the first space shuttle built? How does the International Space Station work? How is powdered aluminum used on the space shuttle? How did the International Space Station get into space?
The International Space Station took over a decade to complete. Most of the pieces that you see here were launched by the Space Shuttle. In fact, this was one of the main purposes of the Space Shuttle. It was to build the Space Station. We can't go over every single mission. That wo...
How are the space shuttle and the Saturn rocket different? How does a space shuttle fly? How does the International Space Station work? What does a rocket engine push against in space? What is an Estes rocket engine made from? How do space shuttles aid in space exploration?
Regardless of whether you're in your living room or orbiting thousands of miles above Earth in the international space station, when nature calls, you have to listen. But when you're in zero gravity, something as simple as going to the bathroom can turn into a major challenge. It's ...
Some of the space programs' goals include the upcoming return to and eventual settlement of the moon, along with the pending manned voyages to Mars. The International Space Station (ISS) provides a cooperative platform on which to research the critical challenges of putting humans in space for ...
D We can video chat with astronauts aboard the International Space Station, but how about communicating with a submarine(潜艇)? Not so easy. The lack of realistic methods for sharing data between underwater and airborne devices(设备) has long been difficult for scientists and engineers.Now, rese...
Unlike NASA's out-of-control Upper Atmosphere Research Satellite (UARS), the International Space Station should make a guided re-entry when it's ready to come down. So the huge orbiting lab shouldn't pose a danger to people on the round.
