First-time astronaut Reid Wiseman arrived at the International Space Station two weeks ago, but zero gravity still surprises him.

‘Laughed so hard, I cried yesterday during dinner. Tears don’t run down your cheeks in space,’ wrote Wiseman, who is sharing his observations and pictures with a growing following on Twitter. ‘Still adjusting to zero g. Just flipped a bag upside down to dump out its contents. #doesntworkhere,’ Wiseman tweeted last week. His favourite picture so far is a view of the northern Australian coast. ‘The way the clouds and the red desert met the ocean, it’s burned in my mind,’ Wiseman said during an inflight interview with CBS News broadcast on Monday.
