SpaceX Crew Dragon spacecraft nears last parachute tests before astronaut launch debut

SpaceX’s Crew Dragon spacecraft is likely just a few weeks away from its last few parachute drop tests, the successful completion of which should give NASA all the technical data it needs to okay its astronaut launch debut.

After facing several major failures during intentionally challenging drop tests both last year and the year before, SpaceX and supplier Airborne have been working relentlessly to better understand the complex physics behind parachutes and then design and build better ones with that information.

Most recently, SpaceX has been aggressively testing the latest Mark 3 (Mk3) parachute variant with great success and has completed some two-dozen consecutively-successful drop tests since October 2019. Now, NASA and SpaceX are working together to settle on a design for two final Crew Dragon parachute tests, the results of which will almost certainly determine when the spacecraft’s astronaut launch debut will occur.

As previously discussed on Teslarati, SpaceX – in pursuit of the safest and most reliable spacecraft possible – has quite literally been pushing the envelope of parachute engineering and the immensely complex physics behind their behavior during deployment.

“According to NASA, the incredibly extensive testing SpaceX has had to do to satisfy the agency’s requirements has lead the company to develop “a better understanding of how to safely design and operate parachute clusters”. As of September 2019, SpaceX has reportedly completed 48 distinct parachute tests, of which one or two apparently failed.

In response to the additional testing and analysis NASA required after a recent April 2019 chute failure, SpaceX has essentially been forced to push the state of the art of parachute design and modeling to new levels. NASA says that SpaceX has begun to model certain conditions and newfound failure modes in ways that “provide a better understanding of parachute reliability” and have forced NASA to reevaluate its
own standards and certification processes. Shown in the video above, SpaceX recently completed a successful parachute test identical to the attempt that failed in April 2019, a major step towards confirming that the new parachute analysis and design have mitigated prior faults.”

Teslarati.com — September 20th, 2019

Since that NASA report, SpaceX has – based on their own subsequent updates – completed no less than 24 successful Mk3 parachute tests, ranging from single-chute and chute-out tests to the full-fidelity spacecraft launch and recovery that followed Crew Dragon’s January 19th, 2020 In-Flight Abort (IFA) test.

NASA’s Wallops Twitter account has revealed Crew Dragon’s final two parachute tests will be performed with a C-130 cargo plane similar to the one pictured above during a previous SpaceX drop test, implying – unsurprisingly – that they will likely be as closed to full fidelity as possible. For unknown reasons, those final tests will be performed in Arizona instead of SpaceX’s usual California-based locations of choice.

Most likely, those tests will involve a Crew Dragon-shaped simulator that will perform drop tests as if it were a flightworthy spacecraft returning from space. That would involve fairly high-altitude drops in which the spacecraft simulator uses mortars to eject a hatch and deploy drogue chutes, stabilizing Crew Dragon’s orientation before four main chutes are carefully deployed a gentle splashdown or touchdown.

Ultimately, if those tests go exactly as planned and NASA is able to finish reams of paperwork in time, Crew Dragon could be ready for its astronaut launch debut (known as Demo-2) as early as late-April 2020, although May or June may be more practical. In doing so, SpaceX is all but certain to become the first private company in history to launch humans into orbit.

Autonomous vehicle red tape gets slashed by Trump Administration

Published

on

The Trump Administration today made several key moves to help with the deployment of autonomous vehicles by cutting overreaching red tape that has stifled growth and innovation for years.

The moves, which were put forth by the National Highway Traffic Safety Administration (NHTSA), aim to grant temporary exemptions to at least one company currently, although that could expand in the coming months. Additionally, it will work with organizations to develop standards and a sound but efficient regulatory landscape.

Zoox is the only company mentioned explicitly by the Trump Administration in its press release announcing the new terms today. They will receive a temporary two-year exemption that will allow the commercial deployment of up to 2,500 vehicles annually for two years.

There is a potential exemption for Robomart, Inc., which “requests a temporary exemption from certain FMVSS No. 500 requirements for a low-speed vehicle operated by an ADS without a human driver onboard. NHTSA will publish a separate notice seeking public comment on its merits once the initial evaluation is complete,” the agency said.

Here are the five new terms that Secretary Sean Duffy has implemented through the NHTSA today:

  1. Allow Zoox to commercially deploy its robotaxis through a temporary exemption.
    This temporary exemption will allow the commercial deployment of up to 2,500 vehicles annually for two years, subject to an enhanced, adaptable oversight structure that can evolve as Zoox’s technology advances.
  2. Accelerate development of first-ever AV performance standards through a partnership with SAE Industry Technologies Consortia (ITC).
    This partnership will fund a three-year, $5 million “A2SCEND” consortium, bringing together experts to gather data and accelerate creation of the first-ever AV performance standards. This project will inform a single national standard for AV safety to eliminate the patchwork regulatory landscape that has stifled innovation for years.
  3. Publish an interim final rule that allows vehicles manufactured prior to an exemption to be eligible for a commercial deployment exemption.
    This rule will modernize the application process and improve access to exemptions for innovators, including AV developers, by granting the NHTSA Administrator the discretion to apply temporary exemptions to vehicles manufactured prior to the effective date of an exemption grant.
  4. Streamline the application process for Part 555 exemptions by updating guidance and soliciting feedback from the public.
    By updating the Part 555 exemption process—which allows automakers to temporarily sell a limited number of non-compliant vehicles, primarily to test new technologies—NHTSA is aiming to create a more flexible oversight structure for exemptions and summarize recent AV framework activities, including expanded exemption pathways, streamlined crash reporting, and ongoing efforts to modernize Federal Motor Vehicle Safety Standards (FMVSS).
  5. Establish a new Federal Docket for public feedback on NHTSA’s updated safe AV development and deployment guidance.
    NHTSA is updating its technical guidance for AVs for the first time since 2017—focusing on key safety areas like emergency responder interactions, safety management systems, remote assistance, and post-crash behavior to help the industry scale up driverless deployments safely.

Additionally, the NHTSA said it has modernized some safety standards by proposing updates to:

  • FMVSS 102 – Transmission shifting
  • FMVSS 103/104 – Windshield defrosting and wiping
  • FMVSS 110 – Tire placards
  • FMVSS 135 – Braking systems
  • FMVSS 101 – Controls and displays
  • FMVSS 108 – Vehicle lighting
  • FMVSS 111 – Mirrors and rearview display
  • FMVSS 126 – Electronic stability control systems
  • FMVSS 201/208 – Sun visors and warning labels

These changes aim to make the regulatory process for autonomous vehicles more streamlined and efficient, which could help the U.S. gain dominance over autonomous vehicle systems moving forward.

Elon Musk has a crazy prediction about AI in two years

Elon Musk is, in many respects, one of the biggest and most influential figures in modern-day artificial intelligence.

Given that Tesla, SpaceX, and xAI are all looked at in their respective fields as leaders to an extent, each of them has a heavy influence on the future of AI, even though two of them are not thought of, at face value, as AI companies.

Musk has grand expectations for what is to come with AI, not only as a form of assistance to make human lives easier, but to make humans multiplanetary and solve some of the biggest issues that face us today. But even he is astounded by AI’s pace of progress.

He believes that in two years, AI will be so mind-blowing it might be unrecognizable.

This progress can be seen in a variety of ways, but perhaps the most popular way people have shown AI’s progress, especially on social media, is through an incredibly arbitrary way of watching Will Smith eat spaghetti:

This is a great way to show people how AI is improving, especially from a perspective that examines how it can manufacture images and video from prompts. AI is an incredibly complex concept, however, and it goes much deeper than Will Smith eating Italian food.

Musk’s most widely adopted method of AI is likely Tesla Full Self-Driving, which impacts millions of people as they utilize it to increase safety with their travel. Musk has routinely pushed incredibly aggressive timelines for self-driving, especially unsupervised.

Perhaps this perspective is why he feels that things will be solved in a timeframe that is much more aggressive than most of us would think. Regardless, the progress of AI is moving fast, and it seems that Musk’s expectations for it could be high.

But if it can actually achieve full-length motion pictures and even more realistic production value, it will be hard to distinguish between reality and AI very soon.

Tesla just built it 10 millionth car

Published

Tesla just officially confirmed it has built its 10 millionth car, a major milestone for the company that started producing sustainable electric powertrains less than two decades ago.

In that time, Tesla has truly revolutionized the automotive industry, disrupting the idea of what a car should be, how it should be fueled, and how it truly impacts day-to-day life.

Tesla achieved this feat across four production facilities: the Fremont Factory in Fremont, California, Gigafactory Shanghai in China, Gigafactory Berlin in Germany, and Gigafactory Texas in Austin, Texas.

The 10 millionth vehicle was a Diamond Black Model Y.

Over the course of the past roughly 18 years, Tesla has evolved its lineup from a sporty sedan built on a Lotus body to a lineup of various body styles, performance metrics, and other characteristics that make each one unique.

This is an incredible achievement for a company that is young compared to what it goes up against. When Tesla entered the automotive market, Ford, GM, and Stellantis widely dominated the playing field. Since then, Tesla has caused such a disruption that these three massive brands had to scramble to create EV projects of their own.

Despite their best efforts, they have not been able to match the prowess or the effectiveness of Tesla. They are all reliant on Tesla’s charging infrastructure, their software is inferior, and their self-driving projects are elementary in comparison.

Tesla felt its fair share of growing pains over the years as well. As recent at 2019, there were complaints about build quality, paint quality, and overall luxuriousness. These things have all been improved upon through the company’s maturity, and these strides in quality have led to this 10 million vehicle production achievement, something that other small-and-scrappy EV makers will hope to accomplish one day.
