President Donald Trump blamed a delay for a minute-long awkward silence during his Monday night phone call with the astronauts aboard the Artemis II. The president spoke to the four astronauts—Americans Christina Koch, Victor Glover, Reid Wiseman, and Canadian Jeremy Hansen—after 10.30 p.m. ET for just over 12 minutes, praising their achievements after they traveled farther from Earth than anyone else in history earlier in the day. “Today, you’ve made history and made all America really proud,” Trump told the crew, who were some 250,000 miles away from Earth at the time. “Humans have never really seen anything quite like what you’re doing in a manned spacecraft. It’s really special.”
