Weather permitting, the so-called Low Density Supersonic Decelerator will be launched from the Pacific Missile Range Facility at Barking Sands sometime
The vehicle will be carried up by a high-altitude balloon, which will take about two to three hours to reach "float" conditions. Once released, the vehicle will rocket high into the atmosphere and return using a giant parachute.
If successful, the parachute design could be used to slow landers and rovers descending through low-density Martian atmosphere. The more advanced landing technology is considered necessary to accommodate heavier spacecraft and, perhaps, astronauts.
High winds caused the vehicle to miss two previous launch windows, in June and earlier this month.
