April parachute test for manned Dragon had problems


Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit.

 
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs." --San Antonio Express-News

In testimony yesterday before Congress NASA’s chief of human spaceflight, Bill Gerstenmaier, revealed that during a test of the parachute system SpaceX will use on its manned Dragon capsule there was a problem.

The test appears to have occurred last month at Delamar Dry Lake in Nevada, where SpaceX was conducting one of dozens of drop tests it intends to perform to demonstrate the safety of its Crew Dragon spacecraft. This was a “single-out” test in which one of Dragon’s four parachutes intentionally failed before the test. “The three remaining chutes did not operate properly,” Gerstenmaier said.

…The test sled, Gerstenmaier confirmed, was “damaged upon impact with the ground.”

The cause of the failure, which might have been parachute design or a failure in the test equipment (such as the release from the airplane) is still being investigated.

This news, combined with the failure during Dragon thruster tests, also in April, likely guarantees that SpaceX will not launch in 2019. If it were up to SpaceX, I think they could get these issues dealt with and fly, but their customer is NASA, and NASA is notoriously slow at investigating and fixing engineering test problems like these.

My next post above underlines this conclusion.

Readers!
 

We are now in the third week of my annual July fund-raiser for Behind the Black. My deep thanks to everyone who has so far donated or subscribed. The response this year has been wonderful.
 

We are not done yet. This monthly fund-raiser is now half over, and I am hoping the second half will result in as many donations as the first half did. If it does, I will remain free to continue my writing as I see fit, unblemished by the efforts of others to squelch my perspective in this increasingly intolerant world.
 

This year's fund-raising drive is also significant in that it celebrates the 10th anniversary of this website's founding. It is hard to believe, but I have been doing this for a full decade, during which I have written more than 22,000 posts, of which more than 1,000 were essays and almost 2,600 were evening pauses.
 

Therefore, I hope you will please consider donating to Behind the Black, by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below. Your support will allow me to continue covering science and culture as I have for the past twenty years, independent and free from any outside influence.
