How do people in a special airplane flight get to float like there is no gravity – just like astronauts? An aerospace engineer explains.
The constant pressure of gravity affects our thoughts and perception, but it's so constant we haven't noticed – until now.
On Earth the flame from a struck match looks like an inverted teardrop shape and is orange. In microgravity, that same flame is spherical and blue. Heat transfer is different with minimal gravity.
New research has uncovered exactly what happens to the brain when astronauts are in space.
