A WONDER CALLED INTERNATIONAL SPACE STATION

Isn’t a contradiction that we find it difficult to find a vaccine for Covid 19, yet we have been able to build an international space station, the ISS, the first step towards interplanetary voyages.
It has been in existence for 15 years, orbiting at 408 kilometers above Earth at a speed of 8Km/s. Here are some facts and figures:
The space station is 357 feet end-to-end, one yard shy of the full length of an American football field including the end zones.
An international crew of six people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes.
The living and working space in the station is larger than a six-bedroom house (and has six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window).
Astronauts and cosmonauts have conducted more than 221 spacewalks (and counting!) for space station construction, maintenance and upgrades since December 1998.
The large modules and other pieces of the station were delivered on 42 assembly flights, 37 on the U.S. space shuttles and five on Russian Proton/Soyuz rockets.
Six spaceships can be connected to the space station at once.
A spacecraft can arrive at the space station as soon as six hours after launching from Earth.
Four different cargo spacecraft deliver science, cargo and supplies: Northrop Grumman’s Cygnus, SpaceX’s Dragon, JAXA’s HTV, and the Russian Progress.
Through Expedition 58, the microgravity laboratory has hosted more than 2,700 research investigations from researchers in more than 103 countries.
More than 20 different research payloads can be hosted outside the station at once, including Earth sensing equipment, materials science payloads, particle physics experiments like the Alpha Magnetic Spectrometer-02 and more.
On-orbit software monitors approximately 350,000 sensors, ensuring station and crew health and safety.
More than 50 computers control the systems on the space station.
More than 3 million lines of software code on the ground support more than 1.5 million lines of flight software code.
