Trump will become the first sitting president to call astronauts aboard the International Space Station from Mission Control at NASA’s Johnson Space Center in Houston today.It’s part of a trip Trump is making to Johnson to award the Congressional Space Medal of Honor to the crew of the Artemis II, who made history this year on their mission around the moon.It won’t be the first time a president has called the International Space Station, though — just the first time one will have done it from the iconic Johnson Space Center, which has hosted mission control for every crewed NASA mission since 1965’s Gemini 4.In 2011, President Barack Obama called the space station from the Oval Office, and Trump did the same in 2017, during his first term.Trump in the past has proposed slashing funding for or privatizing the space station. In a 2018 budget proposal, the first Trump administration suggested ending the U.S.’ involvement in it. Last year, near the start of his second term, Trump in an executive order proposed building a replacement for it with commercial funding.
