Always wanted to be an astronaut? Thanks to NASA, you may get your chance - for free.

NASA is offering free anti-gravity flights this summer to anyone with a good idea or product pitch for spaceflight but without the cash to test it, Fox News reports.

The space agency will offer spots to individuals, research groups and institutions who develop ideas "that have potential use in future agency products," according to NASA.

Past successes of the NASA program include the invention of a special drilling technique designed for lunar-gravity conditions and a nanofluid coolant system that works in different gravities, Fox reports.

Those technologies, however, were created by companies under contract to NASA . This summer marks the first time non-agency affiliates can take the rides.

Applications for the free flights are being taken by NASA until March 20.

Flights on the anti-gravity vomit comets will begin this August at Ellington Field in Houston and last about 2 hours.

They'll also loop upside-down about 50 times - so riders should make sure to pack some Pepto Bismol in their spacesuits.
