Russian spacecraft plunging towards Earth: are we all doomed?
Probably not, since the capsules are made to be destroyed as they had back towards Earth

But while it is a nightmare scenario for flight controllers, the craft probably poses little risk to those on the ground, or in space.
As the agencies in charge of it are unable to make contact with the ship, and it is running out of fuel, it is being pulled back towards the Earth. But that is not unlike what normally happens to the Progress capsules, which are designed to burn up as they re-enter the Earth’s atmosphere.
On successful missions, the capsules dock with the ISS and the astronauts take the supplies off and refill it with waste to be disposed of. Eventually it is detached from the space station and the thrusters send it back towards the Earth, where it is designed to burn up on re-entry somewhere over the Pacific Ocean.
This time around, the ship is still carrying the supplies that it was sent up to carry, including fuel and oxygen, as well as equipment for the six astronauts on the space laboratory. But the process will still be much the same — as it heads back into space, out of control, the drag and the heat will rip the capsule apart and mostly destroy it.
But it is still unlikely to cause problems. Since the chance of anything landing in an inhabited area is so low, and there will be little if any of the capsule left, the chances are that Progress’s problems will be an expensive and embarrassing mishap rather than a tragic disaster.
