With less than a month to go before NASA’s first crewed launch in nearly a decade, the space agency is still mulling over the details. On May 27, Bob Behnken and Doug Hurley will strap into their Crew Dragon spacecraft and blast off towards the International Space Station. During their stay, the duo will assist fellow NASA astronaut, Chris Cassidy, in maintaining the station as well as conducting several research experiments.

But how long the duo will remain on the station is still up in the air. NASA held a series of briefings on Friday, May 1, detailing the historic mission and how it would work. Hurley and Behnken will launch from Pad 39A at Kennedy Space Center at 4:32 p.m. EDT (20:32 UTC), and dock with the space station 24 hours later.

The exact length of that mission will be determined during their time in space. “It is a trade-off,” Kirk Shireman, NASA ISS program manager said during the news briefing, “between getting the spacecraft back quickly to complete its certification and providing additional crew time on the station for maintenance and research.”

The Demo-2 mission is a test flight. NASA and SpaceX will be using the mission to certify the Crew Dragon spacecraft for regular use to and from the station. So during this flight, the crew will try their hands at manual control and will test and monitor on boars systems during the significant phases of flight: launch, on orbit, and during re-entry.

Once the vehicle has completed its objectives successfully, it will be certified for a crewed flight. Currently, SpaceX is nearing completion on the next Dragon spacecraft, which will ferry four astronauts to the station for a long-duration mission. During the news briefings, SpaceX COO Gwynne Shotwell announced that the spacecraft for that mission is nearing completion and should arrive in Florida in the next couple of months.

Shireman said that the length of the Demo-2 mission was directly tied to that vehicle’s progress. “What we would like to do, from a station perspective, is to keep them on orbit as long as we can until that Crew-1 vehicle is just about ready to go, bring Demo-2 home, allow that certification work to be completed and launch Crew-1,” he said.

Steve Stich, NASA’s deputy manager of the commercial crew program, said that at minimum, the DM-2 crew would stay on orbit about a month. Their maximum stay would be no more than 119 days, due to the potential degradation of the Dragon spacecraft’s solar panels.

Solar panels are how spacecraft get their power while on orbit, and the sensitive components within the hardware degrade over time thanks to the harshness of the space environment. While it’s on orbit, ground control teams will “wake up” the spacecraft once a week to perform health checks and test the solar array’s performance.

“We would like to fly a mission that is as long as we need to for a test flight, but also support some of the space station program needs,” Stitch said.

Originally, Behnken and Hurley were expected to have a much shorter time on orbit. However, NASA officials said they started to explore the possibility of extending their mission six months ago to ensure there were enough astronauts onboard the space station to keep the orbital outpost in top shape. This year the agency is celebrating 20 years of continuous human presence on the space station, and NASA would like to ensure its continuation into the future.

To that end, Behnken and Hurley have spent significant time training to refresh themselves on station systems as well as prepare the potential spacewalks. A new shipment of batteries is scheduled to arrive on station a few days before Behnken and Hurley, and it’s possible that Behnken could be asked to conduct a spacewalk, along with Chris Cassidy.

The top priority for Behnken and Hurley will be to thoroughly check out the Crew Dragon’s systems, followed closely by relieving Chris Cassidy. “There’s a lot of work and activity that can be done in the U.S. segment; certainly more than one person can accomplish on their own,” Behnken explained during a later briefing.

Tesla says it denied Musk CEO replacement report before it was published

Tesla says it responded to the WSJ’s request for comment, denying that it was in search of a new CEO to replace Elon Musk.

Tesla said that it denied seeking a replacement for CEO Elon Musk before a report was published claiming the company was considering a new frontman.

Last night, The Wall Street Journal reported that Tesla’s Board of Directors was looking for Musk’s replacement after he had devoted too much time to his role within the government. The publication revised its headline to the report no fewer than five times, initially stating the company was still seeking a replacement.

By the time the headline revisions were complete, it had outlined that Tesla had looked for a replacement a month ago, but had stopped its search following Musk’s commitment to Tesla during the company’s earnings call last month.

Shortly after the report surfaced, Board of Directors chairwoman Robyn Denholm officially issued a statement on behalf of Tesla:

“Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company. This is absolutely false (and this was communicated to the media before the report was published). The CEO of Tesla is Elon Musk and the Board is highly confident in his ability to continue executing on the exciting growth plan ahead.  – Robyn Denholm.”

Interestingly, Denholm’s statement indicates it had responded to a request for comment from the Wall Street Journal before the report was published. This is especially interesting because Tesla does not typically respond to media outreach, as it dissolved its media department several years ago.

Tesla typically makes its statements publicly on X.

Musk also responded to the report, indicating that the WSJ had committed an “extremely bad breach of ethics” by publishing a “deliberately false article” that did not include Tesla’s “unequivocal denial beforehand.”

Industry leaders such as Elon Musk have always maintained that autonomous robotaxis will make roads safer. A recent blog post from Waymo about the safety of its self-driving cars suggests that Musk’s sentiments are on point.

Way More Safety

Waymo Driver is already reducing severe crashes and enhancing the safety of vulnerable road users. As per a new research paper set for publication in the Traffic Injury Prevention Journal, Waymo Driver had outperformed human drivers in safety, particularly for vulnerable road users (VRUs).

Over 56.7 million miles, compared to human drivers, Waymo Driver achieved a 92% reduction in pedestrian injury crashes. It also saw 82% fewer crashes with injuries with cyclists and 82% fewer crashes with injuries with motorcyclists. Waymo Driver also slashed injury-involving intersection crashes by 96%, which are a leading cause of severe road harm for human drivers. Waymo Driver saw 85% fewer crashes with suspected serious or worse injuries as well.

What They Are Saying

Mauricio Peña, Waymo’s Chief Safety Officer, was optimistic about Waymo Driver’s results so far. “It’s exciting to see the real positive impact that Waymo is making on the streets of America as we continue to expand. This research reinforces the growing evidence that the Waymo Driver is playing a crucial role in reducing serious crashes and protecting all road users,” the Chief Safety Officer noted.

Jonathan Adkins, Chief Executive Officer at Governors Highway Safety Association, also noted that Waymo’s results are very encouraging. “It’s encouraging to see real-world data showing Waymo outperforming human drivers when it comes to safety. Fewer crashes and fewer injuries — especially for people walking and biking — is exactly the kind of progress we want to see from autonomous vehicles,” Adkins stated.

Tesla hints at June 1 launch of Robotaxi platform in Austin

Tesla has hinted at a potential launch date for the Robotaxi service in Austin, Texas.

Tesla just dropped its biggest hint yet about the potential launch date of its Robotaxi ride-hailing platform in Austin, Texas, shedding more light on when to expect it to take off.

In preparation for the ride-hailing service to launch, Tesla has been in talks with the City of Austin for months. It has also spent recent months bolstering its Full Self-Driving suite, aiming for it to handle initially supervised rides with the use of teleoperators to keep things safe and dependable, at least early on.

The company has also said that it expects the Robotaxi service, which will drive passengers in Tesla Model Y vehicles to start, to launch in Austin in June. However, Tesla has not given an exact date.

Now, Tesla is hinting that Robotaxi could launch on June 1, based on a very vague X post it published on May 1:

Of course, this is extremely speculative. However, it’s the first time Tesla has made any suggestions about a potential launch date, so it’s worth taking it seriously.

While the automaker has often missed timelines in the past, most notably the launch of a “feature-complete” Full Self-Driving platform, this is the first time we’ve seen Tesla be so adamant and truly reiterate a target date.

Tesla has not shied away from this June date for the Robotaxi launch yet, something that is worth noting as we move closer to June. All signs point toward Tesla being able to come through on this timeline, and it could be one of its biggest accomplishments yet on the grand scheme of things. The Robotaxi rollout will be controlled and small to start, the company noted on its most recent Earnings Call.

CEO Elon Musk said:

“The team and I are laser-focused on bringing robotaxi to Austin in June. Unsupervised autonomy will first be solved for the Model Y in Austin.”

At first, it also seems as if the first Robotaxi rides will be available to a select group, as Musk said the ability to order one will not be available to the general public until later in the month. He also said the initial fleet will be between 10 and 20 vehicles:

“Yeah. We’re still debating the exact number to start off on day one, but it’s, like, I don’t know, maybe 10 or 20 vehicles on day one. And watch it carefully. They scale it up rapidly after that. So, we want to make sure that you’re paying very close attention the first time this happens. But, yeah, you will be able to — end of end of June or July, just go to Austin and order a Tesla for autonomous drive.”

While the June 1st date of the Robotaxi launch is extremely speculative, Tesla seems convinced that its vehicles could already handle this task. It would be something to see them come through on this date, especially on the first day of the month.
