those stays in orbit were always temporary. However, when three astronauts moved into theInternational Space Station(ISS) for a four-month stay, it marked the beginning of a decade and a half of a permanent human presence in space. The arrival of these three astronauts at the ISS on N...
And since 1998, the United States, Russia, the European Space Agency, Canada, Japan and other countries have been building and operating the International Space Station (ISS) in Earth orbit. With the ISS, humans have been living and working in outer space for more than 10 years. In this ...
How was the International Space Station built? How does the International Space Station obtain its air? How does the International Space Station work? How does the International Space Station stay in orbit? How do astronauts get into the space shuttle? How does the space shuttle move in space?
The ISS has a low Earth orbit only 214 miles (343 km) high, so it is one of the objects that completes one orbit of the Earth every 90 minutes (16 per day). When the ISS returns to its starting point, the Earth has rotated to the east by 22.5 degrees. By tilting the orbit wit...
The impact of spaceflight on the immune system has been investigated extensively during spaceflight missions and in model experiments conducted on Earth. Data suggest that the spaceflight environment may affect the development of acquired immunity, and immune responses. Herein we summarize and discuss the...
To Deorbit or Not To Deorbit? Next Friday, we will discuss the International Space Station (ISS). How did it come to be, how was it built, what did it accomplish, what is still in the wings for it, when and how will it be decommissioned, and, most importantly, what will come nex...
For instance, NASA’s Crew development programme supports Boeing’s Crew Space Transportation 100 craft, which aims to shuttle astronauts to, and from low-Earth orbit either to the ISS or other space stations such as Bigelow Aerospace’s inflatable structure, proposed for orbit in 2015. If ...
Here’s what SpaceX does: It takes things to space for people, for money. And as we established, here’s what SpaceX really does: It’s an innovation machine, trying to solve one big problem—the astronomical cost of space travel—because that’s the key to making humanity a space-far...
Goal: Launch something into orbit before Musk runs out of money Phase 1 really started before SpaceX even existed, back in mid-2001 while Musk was still at PayPal. Strongly considering entering the space arena as his next move, Musk did what everyone does when they want to become a world...
Ascent Vehicle (MAV) first, before sending humans. Automatic equipment chemically breaks down Martian air into breathing oxygen and fuel for the return trip. Only when the tanks are full does the first expedition leave Earth. This is called in-situ resource utilization, or "living off the land...
