The International Space Station

The ISS is a multi-nation super satellite, the largest single construct in space, made between 1998 and 2011.

  • As of 2018, 230 astronauts and 18 countries have visited the International Space Station. It includes contributions(money and resources) from 15 nations like Russia, USA, and Europe.

  • The ISS is assisted (and even controlled) by mission control centers in Houston and Moscow, along with a payload control center in Huntsville, Ala.

ISS Journey Around Earth

The International Space Center circles the globe every 90 minutes at a speed of 17,500 mph. It flies at an altitude of 248 miles above Earth.

It holds a crew of three to six people, and for a long time, used the Russian Soyuz spacecraft as a way to transport astronauts. SpaceX has sent 2 more astronauts in May 2020, using their Special Dragon Spacecraft, courtesy Elon Musk.

Activities of ISS

Astronauts mainly perform experiments and do maintenance at the ISS. They also do some personal care and exercise, reach out to Earth to conduct some media or school events, and occasionally perform spacewalks. They also use a bit of Twitter.

Human health research, especially eye problems are a major activity. Biological activities, animal tests and testing of appliances in space is also done.

Structure Of ISS

The ISS weighs 861,804 pounds, with livable space comparable to a Boeing 747 Jumbo Jet.
It consists of labs, living quarters, solar panels and connector nodes.

Sequels Prequels

The original story and its continuation in the two sequels released in the 80s had limited computer graphics technology, which eventually became better in the 90s. The Director, George Lucas, then released three ‘prequels’ which had better technology and visual effects, though the story wasn’t in the same league.
