Last night at 22:22 GMT (2:22 a.m. in Reunion), the Cygnus spacecraft exploded shortly after launching. It was heading to the International Space Station, carrying food supplies and material (5,000 pounds / 2,268 kilograms) to the scientists who have been up there for a while.
Of course, this is a great loss, and an expensive one (the spacecraft and the rocket cost more than 200 million $). The ISS team won’t be starving though, they still have a lot of food on board.
