After scrapping all of its planned test launches earlier this month, NASA will today attempt to release its Low Density Supersonic Decelerator (LDSD) from the edge of space. The rocket-powered, flying saucer–shaped landing vehicle will then return to Earth on a dramatic path through Hawaii's skies. Watch it live, here!

The Saturday balloon launch window extends from approximately 8:15 a.m. to 9:00 a.m. HST (11:15 a.m. to 12-noon PDT). The balloon will take approximately 2-3 hours to achieve float conditions. Shortly thereafter, the test vehicle will be released from the balloon and the test will begin.

Pictured here is a timeline events for the planetary landing test:

Principle investigator Ian Clark said earlier this month that he and his team were "very optimistic," and "hoping to test the vehicle at the end of the month" – so fingers crossed, everyone!
