Update: Today is your last day to send your name into space, and eventually to Mars, with a new NASA program. Sign up for your ‘boarding pass’ to space and Mars as part of NASA’s Orion Mission testing. More info about the Orion and future Mars mission here.

Your name will begin its journey on a dime-sized microchip when the agency’s Orion spacecraft launches Dec. 4 on its first flight, designated Exploration Flight Test-1. After a 4.5 hour, two-orbit mission around Earth to test Orion’s systems, the spacecraft will travel back through the atmosphere at speeds approaching 20,000 mph and temperatures near 4,000 degrees Fahrenheit, before splashing down in the Pacific Ocean.

But the journey for your name doesn’t end there. After returning to Earth, the names will fly on future NASA exploration flights and missions to Mars. With each flight, selected individuals will accrue more miles as members of a global space-faring society.
