(Okay, we'll try to stop saying Benjamin.) For the results, Kayak looked at both domestic and international round-trip flights in economy class; evaluating search dates between July 1, 2016 and June 30, 2017 for travel dates in that same period. Of course, What are the cheapest days to fly? is a complicated question.
A Russian Soyuz capsule usually takes at least two days to rendezvous with the ISS, because of the carefully timed dance of manoeuvres that must take place for a spaceship to safely meet the orbiting laboratory. Using a new launch process, three astronauts have now made the trip in just under 6 hours.
Asked by Tom Davies. Nowadays all astronauts on a spacewalk will be residents of the International Space Station (ISS). To stay in orbit the ISS has to move at about 27,500 kilometres (17,000 miles) per hour so technically spacewalking astronauts are already moving at an incredible speed. Relative to the station, however, a spacewalking astronaut does not tend to move particularly fast.
