SOLAR SYSTEM

Detailed explanation-1: -An international crew of seven people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes. Sometimes more are aboard the station during a crew handover. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets.

Detailed explanation-2: -Statistics. As of May 2022, people from 44 countries have traveled in space. 622 people have reached Earth orbit. 628 have reached the altitude of space according to the FAI definition of the boundary of space, and 565 people have reached the altitude of space according to the American definition.

Detailed explanation-3: -The Space Shuttle-composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank-carried up to eight astronauts and up to 50, 000 lb (23, 000 kg) of payload into low Earth orbit (LEO).

Detailed explanation-4: -The ISS is designed to support a crew of six people at one time.

Detailed explanation-5: -You can buy tickets for a voyage into space with Virgin Galactic, with tickets currently on sale for $450, 000. Admittedly, $450, 000 USD isn’t exactly small change, but it’s a lot less expensive than the $20 million that previous space travellers have paid.

Detailed explanation-6: -Without space programs, we wouldn’t have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras. There’s also medical research happening in space right now that could cure diseases and prolong human lives, and these experiments can’t be done on Earth.
