NASA recently invited members of the media to apply for access to SpaceX’s Crew Dragon in-flight abort (IFA) test and, as of December 5th, the company reaffirmed that the crucial test is still on track to launch just weeks from now.

In September, SpaceX CEO Elon Musk revealed that Crew Dragon’s IFA spacecraft and Falcon 9 was scheduled to arrive in Florida within a few weeks. Days later, NASA confirmed that the rocket and spacecraft arrived in Florida on October 3rd, sooner, in fact, than Musk had predicted. Over the next few weeks, SpaceX technicians and engineers effectively closed out Crew Dragon capsule C205, priming it for operations and installing its body panels.

On November 13th, about six weeks after arriving in Florida, SpaceX successfully tested Crew Dragon’s redesigned propellant plumbing and high-pressure gas systems by static firing its Draco thrusters and SuperDraco abort engines. The successful static fire test lasted around 9 seconds, mirroring the SuperDraco impulse and thruster inputs the spacecraft would need to demonstrate in an actual in-flight abort. Crew Dragon has four sets of two SuperDraco engines capable of producing a combined thrust of more than 130,000 lbs (570 kN), almost as much thrust as the original SpaceX Merlin 1D engines used on Falcon 9 in the early 2010s.

Meant to verify that SpaceX has successfully redesigned Crew Dragon after the spacecraft suffered a catastrophic explosion during a very similar static fire attempt, November 13th’s was followed by an exhaustive hardware inspection and data review, some of which is likely still ongoing. Although NASA’s media invite suggests that a given launch event could be just a month or so away, there is a ton of uncertainty when dealing with major launches of new hardware (like Crew Dragon), meaning delays are all but guaranteed.

During a pre-launch media briefing ahead of SpaceX’s CRS-19 Cargo Dragon launch, director of Dragon mission management Jessica Jensen answered a question about Crew Dragon’s IFA test, cautiously stating that SpaceX teams are “targeting [a] December” launch. During SpaceX’s December 5th CRS-19 launch webcast, Dragon Engineering Manager John Federspiel briefly brought up Crew Dragon, noting that SpaceX was completing “minor refurbishment” following its successful static fire.

Most notably, he stated the IFA test was “targeted for February of 2020”, while Crew Dragon’s subsequent ‘Demo-2’ astronaut launch debut was expected to follow no earlier than (NET) “the first quarter of [2020]”, implying either February or March.

As it happened, SpaceX and several media outlets almost immediately attempted to correct the record, instead suggesting that Crew Dragon’s abort test is still tracking towards a launch later this month. Given that a senior Dragon engineering manager was the one to unblinkingly – and without correction – state that IFA is NET February 2020, there’s a strong possibility that he is technically correct but was not supposed to publicize the mission’s delay. At the same time, SpaceX appears to be firm on its claim that IFA is still aiming for a late-December launch. Delays would be no surprise – Crew Dragon’s Demo-1 launch debut took an agonizing three months to go from heading to the launchpad for the first to actually lifting off, almost entirely due to minor technical bugs and NASA paperwork.

Regardless, with less than four weeks left in 2019, SpaceX has an exceptionally tight schedule ahead of it to meet that December 2019 IFA launch goal and will effectively have to static fire IFA’s Falcon 9 before the end of the week or crush Crew Dragon’s inaugural processing time by at least a factor of four to achieve it. As such, a delay in 2020 should be all but expected at this point. With any luck, however, Crew Dragon will successfully perform its in-flight abort within the next 4-8 weeks, leaving SpaceX in a good place to prepare for its inaugural astronaut launch a few months later.

The Tesla Cybertruck may be polarizing, but it is a vehicle that has captured the interest of the motoring world and beyond. And while neither Tesla nor Elon Musk has announced any details about where the upcoming all-electric pickup truck would be produced, this has not deterred a government official from extending an offer to the CEO. 

In a recent tweet, Alaska governor Governor Mike Dunleavy invited Tesla CEO Elon Musk to consider utilizing the state’s resources to build the electric car maker’s premium vehicles. The governor specifically mentioned the company’s recently-unveiled Cybertruck in his offer, stating that AK stands above other areas when it comes to balancing resource development. 

“Hey @elonmusk & @Tesla: Let’s talk about utilizing #Alaska’s vast resources to help build #Tesla cars and the new Cybertruck. Nobody in the world balances resource development and environmental stewardship better than us,” he wrote. 

Hey @elonmusk & @Tesla: Let’s talk about utilizing #Alaska’s vast resources to help build #Tesla cars and the new Cybertruck. Nobody in the world balances resource development and environmental stewardship better than us.

— Governor Mike Dunleavy (@GovDunleavy) December 4, 2019

Dunleavy’s invitation is quite notable considering that the governor has reportedly maintained a controversial stance on climate action, a topic that Tesla CEO Elon Musk is very particular about. Over his tenure as Alaska’s governor, critics have argued that Dunleavy’s administration has done very little to combat climate change, as shown when he disbanded the state’s climate response task force just months after assuming office.  

Neither Tesla nor Elon Musk has posted a response to the governor’s open invitation so far. 

Yet, behind Dunleavy’s controversies with his administration, it is difficult to deny that Tesla and Elon Musk are now being perceived as a potential economic booster for areas where its facilities are located at. Reno, NV, for example, is seeing businesses come to the area due to the presence of Gigafactory 1. A facility that produces electric cars in Alaska will likely have the same effect. 

What nobody saw was all the other businesses that moved to Reno just because Tesla was here. Tesla put Reno on the map, but now we’re playing catchup. The paper reports apartment complexes waiting to be built for lack of skilled carpenters. Reno is a boomtown.

The Tesla Cybertruck is Tesla’s most radical creation to date. Built with a rigid ultra-strong stainless steel exoskeleton, the all-electric pickup truck is tough and capable of being put through serious punishment. This is something that was highlighted by auto veteran Jack Rickard in a discussion on YouTube’s EVTV channel. Rickard noted that the Cybertruck’s polarizing design was not just put in place to make the vehicle unique; it is also functional. 

Thanks to its polarizing XY design, the Cybertruck will not require a stamping press or a paint shop. This makes the vehicle easy to make, and this opens up the potential of a production line that is more compact and efficient than those adopted by the company for its previous cars like the Model 3. With this in mind, Tesla may be able to produce the Cybertruck in facilities that are not as expansive as the Fremont factory of Gigafactory 3 in Shanghai. This, of course, could accelerate the rollout of Elon Musk’s boldest, most futuristic vehicle to date.

SpaceX has successfully launched Cargo Dragon’s 19th space station resupply mission and says that the event also marked a symbolic Falcon 9 booster landing milestone.

At 12:29 pm ET (16:29 UTC), Falcon 9 lit its nine fresh Merlin 1D engines and roared off of SpaceX’s Cape Canaveral LC-40 launch pad, beginning a nine-minute trip to place Cargo Dragon in low Earth orbit (LEO). That flight-proven Dragon capsule – C106 – was supported by a rare new Falcon 9 booster – B1059 – on its inaugural flight.

Seven or so minutes after launch and a few minutes after a successful reentry burn and landing burn, Falcon 9 booster B1059 gently touched down aboard drone ship Of Course I Stil Love You (OCISLY), SpaceX’s 46th booster landing. Perhaps even more impressive, SpaceX says that with the recovery, Falcon 9 B1059 became the 20th booster to successfully launch and land, rounding out a rocket lineage that stretches all the back to April 2016.

April 2016 marked the inaugural launch and landing of a Falcon 9 booster at sea, the first success after several failed attempts. About a year later, that booster, B1021, became the world’s first reused liquid-fueled rocket booster in March 2017, a milestone that set SpaceX’s pace for the next several years to come.

In the ~33 months since SpaceX debuted the world’s first reusable liquid rocket booster, the company has leaned heavily into the standard it set then, becoming one of the world’s most prolific launch providers and continually working to make its rockets as affordable and capable as possible. As of CRS-19’s flawless December 5th launch and landing, SpaceX has performed 46 successful booster landings, with three Falcon Heavy missions representing an outsized 7 of those thanks to their three first-stage boosters.

All told, Falcon 9 alone has now completed 39 successful landings, meaning that of the rocket’s 76 total launches, more than half have been followed by booster recovery – this despite the fact that Falcon 9 debuted in 2010, while booster landings debuted in the final days of 2015.

After a relatively gentle launch and landing offered by Cargo Dragon’s lighter mass and lower target orbit, Falcon 9 B1059 should be a prime candidate for rapid reuse in the near future, perhaps supporting one of the two-dozen Starlink launches SpaceX has planned for 2020. Up next for SpaceX is a commercial communications satellite launch no earlier than December 15th, followed by either one or two more launches in the last week or two of the month, year, and decade.

Tesla CEO Elon Musk has won a defamation lawsuit brought forth by British caver Vernon Unsworth. The jury of the Los Angeles federal court found Musk to be not liable for $190 million in damages asked by Unsworth. Musk’s Twitter exchange with Unsworth did not meet the legal standard for defamation, according to the court ruling on Friday.

Musk and Unsworth were involved in a war of words in the public eye after the Tesla CEO offered his help in the 2018 Tham Luang cave rescue in Thailand, where a team of junior soccer players was trapped. Musk offered multiple Tesla engineers, along with a small submarine to Thailand that was intended to rescue the boys from the cave.

Instead, Unsworth said the help from Musk was not genuine and accused him of running a “PR stunt” that had “absolutely no chance of working” and told him to “stick his submarine where it hurts,” in an interview with CNN. Musk responded with a tweet that insulted Unsworth, calling him a “pedo guy”, that has since been deleted. Musk stated the insult was commonly used in his native South Africa.

Musk testified in a Los Angeles courtroom on Tuesday and Wednesday and stated the tweet was not meant to be taken in a literal way. In fact, Musk did not realize Unsworth was apart of the search and rescue operation and thought he was “just some random creepy guy.” Musk apologized and said the tweets were “obviously a very off-the-cuff response.”

In court on Thursday, December 5, Unsworth said the words Musk used to describe him “humiliated him”. He told jurors, “It feels very raw. I feel humiliated. Ashamed. Dirtied. Effectively, from day one, I was given a life sentence without parole. It hurts to talk about it,” as he held back tears.

The $190 million Unsworth requested comprised of $150 million in punitive damages and $40 million for assumed and actual damages. However, Musk will not be required to pay this sum, a victory for the man responsible for bringing electric car company Tesla to the forefront. “my faith in humanity is restored,” Musk said as he left the courtroom.

All of the boys trapped in the cave survived. The only fatality took place during the search and rescue mission when a diver lost his life during the operation.

SpaceX says Crew Dragon’s upgraded “Mk3” parachutes are almost ready to safely return astronauts to Earth and need to pass just a few more consecutive tests before NASA will have the data it needs to qualify them.

Although SpaceX originally hoped to pursue a program of propulsive landing for Crew Dragon and Cargo Dragon space capsules, that effort was canceled to avoid the major cost increases and delays NASA’s qualification certification requirements would have triggered. Already designed with parachutes as a backup, SpaceX quickly pivoted and redesigned those parachutes as the primary (if not sole) method of gently landing astronauts back on Earth.

That decision was likely made in late 2016 or early 2017 and CEO Elon Musk announced the program’s cancellation – as well as plans for “Red Dragon” Mars landings – in July 2017. For the next 18 months, SpaceX worked with suppliers and NASA to design and test a parachute system up to the space agency’s extremely rigid standards. Coincidentally, Cargo Dragon suffered a significant (but survivable) parachute failure the same year when one of its three main chutes failed to deploy before splashdown. Additionally, Crew Dragon’s first “Mk1” parachutes suffered their own failures during testing.

A Mk2 variant was designed and built to account for Mk1’s issues, but it too suffered failures during field tests, particularly struggling to make it through tests simulating the failure of one Dragon’s main parachutes. As a result, NASA further required SpaceX to add a fourth parachute, requiring a whole new round of tests and experimentation due to the significantly different dynamics it introduced. Mk2 testing continued into 2019 but SpaceX quickly switched gears and worked with its supplier to design an even more upgraded “Mk3” parachute, building off of a cutting-edge program to model parachute deployment more accurately than ever before.

Over the course of 2019, SpaceX began to extensively test Mk3 parachutes with a variety of drop tests. Unfortunately, even Mk3 suffered a failure or two at first, leading SpaceX and its supplier to refine the design even further.

“[In October and November,] SpaceX says it successfully completed thirteen consecutive tests of Crew Dragon’s new Mk3 parachutes in less than two weeks. That essentially blew [NASA administrator Jim] Bridenstine’s expectations out of the water, as SpaceX surpassed his predicted 10 tests and did 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.”

Teslarati — November 3rd, 2019

In the latest chapter of the Crew Dragon parachute saga, on December 4th, SpaceX tweeted that the spacecraft’s upgraded Mk3 chutes recently completed their seventh successful “system test”. On November 3rd, CEO Elon Musk tweeted that one such multi-chute test had already been completed but said SpaceX wanted to successfully complete ten such consecutive tests before it would feel fully confident in the upgraded parachutes.

If the seven tests SpaceX is now describing are part of the same planned series that kicked off in early November, then those seven were likely consecutive successes and leave just three more tests (give or take) to go. Additional testing may well be required by SpaceX, NASA, or both parties, but if Mk3 continues to perform as well as it has over the last two months, Crew Dragon’s recovery systems ought to be well on their way to NASA certification. Once NASA gives the go-ahead on Crew Dragon’s parachutes (and every other facet of the spacecraft), SpaceX can proceed with its Demo-2 mission, set to be SpaceX’s inaugural astronaut launch and likely to mark the first time the US has launched its own astronauts in nearly nine years.
