Like in your home, all of the onboard systems of the ISS require electrical power. Eight large solar arrays provide electrical power from the sun. Each array is 240 feet (73 meter) long and — cumulatively-speaking — they cover an area of around 27,000 square feet (2,500 square ...
This crew spent 84 days in orbit, conducted experiments and photographed comet Kohoutek. Skylab was never meant to be a permanent home in space, but rather a workshop where the United States could test the effects of long-duration space flights (that is, greater than the two weeks required ...
How fast you need to move to keep in a circular orbit around another body is dictated by how far the two bodies are separated from each other. Planets closer to the Sun are orbiting faster than Earth, with Mercury traveling 1.6 times faster than Earth at 105,000mph(47.4km/s). At the ...
they’ve captured the public's imagination. The Starlink satellite train is often mistaken for UFOs because of its otherworldly appearance. However, this striking formation is short-lived; as the satellites ascend to theiroperational orbitat 340 miles (550 kilometers), they disperse and blend into...
Two satellites are in circular orbits around Jupiter. One, with orbital radius r, makes one revolution every 14 h. The other satellite has orbital radius 3.9r. How long does the second satellite take to make one revolution around Jupiter?
As humanity looks towards expanding activity from low Earth orbit to the Moon and beyond, resource use efficiency and self-sustainability will be critical to ensuring success in the long term. Furthermore, solutions developed for the stringent requirements of space will be equally valuable in meeting...
These concerns, coupled with the challenging climate of the moon and the rise of space stations as our primary outposts for cosmic research, have prevented another lunar landing. However, new plans have recently been revealed that seem to indicate we'll be back on the moon before too long. ...
Although the vast majority of the food available on the ISS comes from a standard set of 200 food and beverage items -- with much of it sent to the space station long before new astronauts arrive -- each astronaut gets to pick a small set of "bonus containers" of special food. By sma...
Each test can start at the usual 200 x 200 kilometer Crew Dragon insertion orbit or any other low orbit. Normally, Dragon and Falcon separate then. But here Dragon starts to spin, with the Falcon stage still attached. The spin axis should point near the sun. Then Dragon’s solar arrays ...
The initial toilets on the ISS were created in the early 2000s, and were designed to strap the astronauts to the toilet while suction was used to create a vacuum, which prevented any solid waste from escaping. Urinating was even more glamorous, with each astronaut having their own personal ...
