As the saying goes, above all, don’t try to do the same thing… in your own space station! Lighting a candle in space carries risks. However, this is the experience that two astronauts from the Chinese space station have just undergone. They wanted to show how flames burn in the absence of gravity.
In space, flames are spherical
And in such circumstances, the flames burn strangely. No teardrop shapes like on our good old Earth. In space, it is the reign of spherical flames. The cause is the weaknesses of the convection currents which allow the flames to spread in all directions.
Remember that, since the fire that occurred on board the Mir space station in 1997, the instructions have been quite strict in this area for astronauts. Combustion experiments aboard the International Space Station are conducted in a dedicated rack. Even if NASA has also already carried out experiments “open”. But it was on board a craft… without a crew!
