An anonymous tech at NASA snuck a laser-engraving of Portal 2's Wheatley and the quote "In spaaaaaaace!" onto the Japanese HTV-3 resupply craft to the ISS.
"NASA in no way officially endorses secretly laser-engraving characters from Portal onto their spacecraft," the Portal 2 team wrote on their blog. "Believe it or not, they don't even officially endorse Portal 2, despite the fact that it's a really excellent game."
The craft launches on Friday, July 27. You can watch the event starting at 9:15 EST on the NASA TV website.
