Russia has lost all contact with a Progress resupply ship that was scheduled to take food and supplies to the International Space Station.
Carrying over 6,000 pounds of food and equipment, the last contact had with the spacecraft showed it spiralling uncontrollably in a low Earth orbit. The fear is that if they can't regain control of the craft it'll burn up in Earth's atmosphere.
Former ISS astronaut Chris Hadfield tweeted the last video that was received by Russia's space agency Roscosmos saying: "Bad thing to see out the spaceship window."
While this is obviously bad news for Roscosmos, it's not actually the end of the world for the astronauts on board the ISS. NASA prepares for every eventuality, including failed resupply missions, so the crew still have more than enough food to last them until August - when the next resupply mission is launched by Space X.
Of course what this does mean is there's more pressure on Space X because if that launch fails, well then they'll be in a bit of a pickle. Of course when we say 'pickle' what we actually mean is that they'll still be fine they just might have to evacuate the station.
