Just in case you didn’t realise how big the International Space Station (ISS) actually is, Astronaut Terry Virts has put this into perspective for you in one single tweet.
Flight engineer Virts joined the International Space Station 100 days ago and has posted some truly amazing selfies and spacewalk images showing the sheer scale of this orbiting giant.
Just a week ago NASA broadcast a live stream of the astronauts during a spacewalk. Since then, Virts and commander Barry "Butch" Wilmore have completed their third spacewalk in eight days, having installed 400 feet of cable and several antennas on the ISS.

The 5-hour, 38-minute spacewalk was the third for Virts and the fourth for Wilmore. Virts has now spent 19 hours and two minutes outside during his three spacewalks and Wilmore 25 hours and 36 minutes in the void of space during his four excursions.
The extensive work carried out on the ISS will aid future operations and help deliver crews to the space station.
The International Space Station weighs around 450 tons and covers approximately 108.5 meters by 72.8 meters, which is roughly larger than a football field.
