WASHINGTON — SpaceX stated Nov. three that it has now carried out 13 consecutive profitable checks of a brand new parachute design for its Crew Dragon spacecraft after overcoming preliminary issues with it.
In a tweet, SpaceX posted video of the most recent take a look at of the “Mark three” parachutes it’s growing in cooperation with Airborne Programs. The most recent take a look at “demonstrated the parachute system’s potential to land the spacecraft safely within the unlikely occasion that one of many 4 primary parachutes fails,” the corporate stated.

A SpaceX spokesperson stated Nov. three that take a look at within the video passed off Oct. 31. It was the primary time that the corporate examined three Mark three parachutes concurrently, with the earlier 12 profitable checks every involving a single parachute.
SpaceX introduced final month it was engaged on the brand new Mark three parachute design, meant to offer increased margins of security than the sooner Mark 2 design. “We predict the Mark 2 parachutes are protected, however the Mark three parachutes are probably 10 instances safer,” Elon Musk, chief government and founding father of SpaceX, stated at an Oct. 10 occasion on the firm’s Hawthorne, California, headquarters with NASA Administrator Jim Bridenstine. “I believe that the Mark three parachutes, for my part, are the perfect parachutes ever, by lots.”
Testing of these new parachutes, although, didn’t begin nicely, SpaceX acknowledged. The corporate stated the most recent take a look at was the 15th for the Mark three parachutes. The primary two checks, reaching involving a single parachute, weren’t profitable.
These first two checks, an organization spokesperson stated, concerned hundreds a lot increased than what the parachute would see in regular operation. “Consequently, these two improvement checks resulted in failures that had been addressed with design reinforcements which have confirmed sturdy in subsequent testing.”
SpaceX stated it labored with Airborne Programs and “quickly iterated” on the Mark three parachute design, finishing up 12 single-parachute checks over seven days previous to the three-parachute take a look at.
These checks look like those that Kathy Lueders, NASA industrial crew program supervisor, was referring to in feedback at an Oct. 30 assembly of the NASA Advisory Council’s human exploration and operations committee. “We’ve been working by means of totally different chute testing. SpaceX guys did 12 chute checks in week as we’re working to perfecting the Mark three design,” she stated in a short dialogue of parachute work.
“We’re persevering with to work with them on what that schedule is and finalizing that,” she added. “We’ll be taking a look at understanding ultimate take a look at outcomes as we transfer into the December timeframe.”
Past these feedback there was little dialogue on the committee assembly on parachute testing regardless of the emphasis NASA was putting on that a part of SpaceX’s industrial crew work. “The best precedence has been the parachutes,” Bridenstine stated throughout his Oct. 10 go to to SpaceX. “Elon has instructed me, and he’s confirmed me, that that’s the place their precedence is. They’re placing as a lot sources and manpower as they’ll to getting these parachutes prepared.”
There had been trade rumors that at the very least one current SpaceX parachute take a look at had failed, which the corporate’s feedback in regards to the unsuccessful first two Mark three checks seem to substantiate. Neither SpaceX nor NASA would touch upon the standing of parachute testing final month past confirming that Mark three parachute testing was underway.
SpaceX stated it could proceed to work with Airborne on “a speedy cadence of testing,” looking for to qualify the Mark three parachutes by the top of the yr, however didn’t disclose a goal by way of variety of checks deliberate.
“We have to get with the Mark three now constant, repeatable efficiency,” Bridenstine stated at SpaceX. “We may see as many as 10 drop checks between now and the top of the yr.” It wasn’t clear if these 10 checks would contain the entire system, which makes use of 4 parachutes, or the testing of a smaller variety of parachutes as within the current sequence of checks. He stated extra checks could be wanted if the efficiency of the Mark three parachutes was considerably totally different from the sooner Mark 2 design.
“We’re simply going full tilt on the Mark three parachutes,” Musk stated on the occasion with Bridenstine. “Folks suppose that parachutes look simple, however they’re undoubtedly not simple.”
