A group has taken to the skies in what's claimed to be the first protest in space - and it's against US President Donald Trump.
The Autonomous Space Agency Network (ASAN) was inspired by late NASA astronaut Edgar Mitchell, who had walked on the moon.
"From out there on the moon, international politics look so petty," he said.
"You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, 'Look at that, you son of a bitch.'"
While they didn't grab Mr Trump by his scruff, ASAN did embrace the spirit of Mr Mitchell's words, sending them out in an enlarged, printed tweet attached to a weather balloon.
It floated 90,000 feet (27,432 metres) into the sky, reaching near space.
The message was intended as a show of solidarity with the March for Science protest, where people will be highlighting the importance of scientists at a time when Mr Trump is planning to strip budgets.
"We sought to send a message of protest to President Trump against his proposed budget cuts for NASA's Earth science program, which is invaluable to understanding climate change and making informed, data-driven policy decisions," an ASAN spokesperson told the Washington Post.
