LOS ANGELES (AP) — NASA hopes to try again to launch a "flying saucer" into Earth's atmosphere to test Mars mission technology after losing the chance because of bad weather.
The space agency is working with the U.S. Navy on the Hawaiian island of Kauai to see if it can get the experimental flight off the ground in late June.
NASA Jet Propulsion Laboratory project manager Mark Adler says winds spoiled every launch opportunity. Winds must be calm for a helium balloon to carry the disc-shaped vehicle over the Pacific so it doesn't stray into no-fly zones.
NASA has invested $150 million in the project so far, and extending the launch window would come with some cost. If the flight doesn't happen this summer, it would be postponed until next year.
