The first critical test flight of SpaceX’s crewed Dragon that will soon launch American astronauts back to orbit and the International Space Station (ISS) from American soil is now less than two days away.

The test flight – called the Pad Abort Test – is slated for the early morning hours of Wednesday, May 6, if all goes well. The key facts and a timeline of the test events are outlined herein.

The test vehicle will reach roughly a mile in altitude (5000 feet, 1500 meters) and last only about 90 seconds in duration from beginning to end.

The May 6 pad abort test will be performed from the SpaceX Falcon 9 launch pad from a platform at Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida. The test will not include an actual Falcon 9 booster.

SpaceX has just released new images showing the Dragon crew capsule and trunk section being moved to the launch pad and being positioned atop the launch mount on SLC-40. See above and below. Together the Dragon assembly stands about 20 feet (5 meters) tall.

A test dummy is seated inside. And SpaceX now says the dummy is not named “Buster” despite an earlier announcement from the company.

“Buster the Dummy already works for a great show you may have heard of called MythBusters. Our dummy prefers to remain anonymous for the time being, ” SpaceX said today.

So, only time will tell if that particular mission fact will ever be revealed.

You can watch the Pad Abort Test via a live webcast on NASA TV:

The test window opens at 7 a.m. EDT May 6 and extends until 2:30 p.m. EDT into the afternoon.

The webcast will start about 20 minutes prior to the opening of the window. NASA will also provide periodic updates about the test at their online Commercial Crew Blog.

Since the Pad Abort Test is specifically designed to be a development test, in order to learn crucial things about the performance of the escape system, it doesn’t have to be perfect to be valuable.

And delays due to technical issues are a very significant possibility.

“No matter what happens on test day, SpaceX is going to learn a lot, ” said Jon Cowart, NASA’s partner manager for SpaceX at a May 1 media briefing at the Kennedy Space Center press site. “One test is worth a thousand good analyses.”

The test is critical for the timely development of the human rated Dragon that NASA is counting on to restore the US capability to launch astronauts from US soil abroad US rockets to the International Space Station (ISS) as early as 2017.

Here’s a graphic illustrating the May 6 SpaceX Pad Abort Test trajectory and sequence of planned events.

The Crew Dragon will accelerate to nearly 100 mph in barely one second. The test will last less than two minutes and the ship will travel over one mile in the first 20 seconds alone.

The pad abort demonstration will test the ability of a set of eight SuperDraco engines built into the side walls of the crew Dragon to pull the vehicle away from the launch pad in a split second in a simulated emergency to save the astronauts lives in the event of a real emergency.
