That’s right: the gravity on the ISS is not 100%, not even 50%, but only 11 % weaker than on the surface of our planet. If you apply Newton’s Law you will realize that the difference between the pull of the Earth’s gravity you are experiencing right now and the one you would have felt aboard the Space Station is only 11%. The International Space Station orbits the Earth at an altitude of 408 -410 kilometers. The force of gravity depends on their masses and mutual distance and is described by Newton’s Law. That’s wrong! So…why do things float on the space station?Īll objects with mass interact via gravity. But many think that “floating” happens because “there is no gravity in Space and the ISS is too far away from the Earth so the astronauts don’t feel the Earth’s gravity”. Most people know that astronauts and things aboard the International Space Station float (thanks, YouTube!). The most common misconception we come across is “there is no gravity in space”. WonderDome is on a mission to set records straight. And yet, the field of public knowledge is filled with astronomical myths and misconceptions.
From excellent outreach programs, educational websites, Astronomy and stargazing apps to the widely available raw data from space and ground telescopes – the access to space information can satisfy even the most inquisitive astro-enthusiasts. And the scientific community is more than happy to share their cosmic knowledge with the non-astronomers. There is, no doubt, a great public interest in Astronomy and space exploration these days.
