  • What is the rarest weather phenomenon?

    A rare weather event also occurred in the Grand Canyon in 2014, when the entire basin of the massive geological monument was fogged in. Here's what happened: As the ground cooled after a hot day and cold, humid air rolled in, low stratus clouds filled the canyon from the ground up.

  • Why do spacecraft need heat shields to enter Earth but not

    May 30, 2018The science of re-entry explained. Rockets are built to withstand the atmospheric forces as they leave the atmosphere, but it's nothing on the scale of re-entry. The reason for these intense forces is the atmosphere. When a spacecraft returns from orbit, or elsewhere, it is travelling at anywhere up to ten kilometres (six miles) a second.
