Life on the Space Station is about to get really weird and lonely – Wired UK
Right now, there are six astronauts aboard the International Space Station, floating 408km above our heads. But soon things could be about to get a lot lonelier up there. Delays in building new spacecraft to get astronauts into space mean that the next trio of astronauts set to join the ISS in April 2020 are facing the possibility of being the space station’s lone occupants for six months.
Space can make your blood flow backwards – BGR
On Earth, gravity aids in draining blood from the head and ensuring a steady flow. In space, that assistance just isn’t there, and slow-moving or stagnant blood can cause clotting. In fact, two of the crew members were found to have clots or partial clots in their left internal jugular vein. Blood clotting is incredibly dangerous when it happens within the body, and if a clot were to form and then travel to the lungs it could create a pulmonary embolism, which is a potentially fatal condition that requires immediate treatment.
