SpaceX successfully completes 13 parachute drop tests of Crew Dragon

Capitalism in space: SpaceX in two weeks has apparently completed a strong of thirteen successful parachute drop tests of its Crew Dragon capsule.

SpaceX says it successfully completed thirteen consecutive tests of Crew Dragon’s new Mk3 parachutes, all of which were completed in less than two weeks. This essentially blows Bridenstine’s expectations out of the water, as SpaceX has surpassed his predicted 10 tests and done so barely three weeks into the tentative 12-week window he set. SpaceX now has plenty of time to either continue testing Crew Dragon’s parachutes or refocus its efforts on other equally important qualification challenges.

Prior to those thirteen consecutive successes, SpaceX suffered two failures during single-parachute Mk3 testing. The first two development tests of the Mk 3 design used loads much higher than the parachutes would ever see in operation in an effort to better understand overall design margins and system performance. After a period of rapid iteration with parachute provider Airborne Systems, the faults responsible for those two stress-test failures were resolved and subsequent drop tests confirmed that Mk3’s suspension lines – the numerous lines connecting the parachute to Crew Dragon – are far stronger than those on Mk2.

Bridenstine had mentioned in a tweet that SpaceX was planning ten drop tests, so the company has now exceeded those plans.

Upcoming schedule of Boeing & SpaceX manned capsule tests

The next two months are going to be a busy time for both Boeing and SpaceX as they attempt to complete the last tests necessary to their respectively Starliner and Crew Dragon capsules before they each launch a manned mission to ISS.

Below is that schedule as of today:

November 4: Boeing will do a Starliner pad abort test, to be live streamed.
November 6: SpaceX will do a final static fire test of Crew Dragon’s SuperDraco abort engines.
November-December: SpaceX will do a series of parachute drop tests of Crew Dragon
December 17: Boeing will launch Starliner unmanned in a demo mission to ISS.
December (third week): SpaceX will complete a launch abort test of Crew Dragon

The article at the first link above provides a lot of detail about both companies’ abort tests.

Assuming these tests all go as planned, both companies will then have completed all engineering tests required prior to their first manned missions. As far as I can tell, the only thing standing in their way at that point will be filling out the voluminous paperwork that NASA is demanding from them.

Crew Dragon successfully tests SuperDraco engines

Capitalism in space: SpaceX’s Crew Dragon capsule, planned for a launch abort test in December, has successfully completed a set of static fire engine tests of two of its SuperDraco launch abort engines.

They next plan a static fire test of all eight engines, followed by that launch abort flight. If all goes well with both, the only thing blocking SpaceX from launching its first manned mission early in 2020 will be the paperwork NASA is demanding they fill out prior to flight.
