Bob Behnken and Doug Hurley launched to the space station on May 30, for an indeterminate amount of time. Their stay on orbit depends upon a few different factors, including solar array degradation, the status of the next Crew Dragon, and landing zone weather. While Bob and Doug do not yet have a definitive return date, NASA officials have said they are looking at August as a return time frame.

The mission, known as Demo-2, is the first to fly humans from Florida since the end of the shuttle program in 2011. It’s also SpaceX’s first mission to carry astronauts. But it won’t be the last. The California-based aerospace company is gearing up for its next crewed mission. Known as Crew-1, this flight will see three NASA astronauts, and one Japanese astronaut soar to the space station inside another Crew Dragon capsule.

The two missions are interconnected. Demo-2 is the final test flight of the Crew Dragon capsule, and at the end of the mission, NASA is expected to certify the craft to regularly carry humans to and from the space station. For nearly a decade, NASA has been solely dependent upon Russia to carry its astronauts, but now, the agency will have more flexibility with flights.

The Crew Dragon spacecraft that will be used for the Crew-1 mission for NASA’s Commercial Crew Program undergoes processing inside the clean room at SpaceX headquarters in Hawthorne, California. The Crew-1 mission to the International Space Station is targeted for later in 2020 with NASA Astronauts Victor Glover, Mike Hopkins, Shannon Walker and JAXA astronaut Soichi Noguchi.

Before Demo-2 launched, NASA officials estimated that the Bob and Doug could stay on station anywhere from one to four months. The agency wanted to see how the Dragon performed on orbit before specifying the length of time the crew would remain on orbit.

“We didn’t prescribe the length of the Demo-2 mission until we got the crew on orbit and we could see the performance of the Dragon,” Ken Bowersox, acting administrator for NASA’s human spaceflight program said on Tuesday. “The Dragon is doing very well, so we think it’s reasonable for the crew to stay up there a month or two. The actual details are still being worked out.”

Bowersox explained that the mission is going well, and the spacecraft is holding up as expected. The Crew version of SpaceX’s Dragon capsule has been to the space station one other time. During its first test flight, called Demo-1. This mission launched in 2019, without people on board. The craft proved it could dock and undock itself with the space station, and even spent about a week attached to the orbital outpost.

Now, NASA and SpaceX are putting the craft through its paces and seeing how well it holds up over time against the harsh environment of outer space. Some of the craft’s most sensitive electronics, namely the solar panels, have a shelf life in space. That time period is limited to 120 days, so NASA wants the crew to come home before that time.

The next batch of astronauts are expected to launch in late August or early September, if all goes according to plan. But, in order for them to launch, Bob and Doug have to come home several weeks before the planned liftoff so that the Dragon can be evaluated and certified.

To that end, NASA is looking at bringing the Demo-2 crew home in late July or early August. This will allow them to help with station maintenance, as well perform a spacewalk or two. Since April, Chris Cassidy has been the sole NASA astronauts on board, as the space station has been operating on a skeleton crew. The addition of Bob and Doug allows the crew to do more routine maintenance, as well as some research experiments.

Bob Behnken is expected to perform at least two spacewalks — one in late June, followed by one in early July. Behnken will join Chris Cassidy in replacing batteries on the space station’s exterior. The batteries were delivered on a recent cargo resupply  mission and will help power the space station.

While Behnken is suited up and working outside the station, Doug Hurley will operate the space station’s robotic arm, helping Behnken and Cassidy move about during their spacewalks.

The plans were brought up in a joint meeting on Tuesday of the National Academies of Sciences, Engineering and Medicine’s Space Studies Board and the Aeronautics and Space Engineering Board.

“It is very likely that by the end of July, we will have conducted some spacewalks with Chris Cassidy and Bob Behnken, replaced some batteries on the ISS, and we’ll — about two months from now — start thinking about bringing Bob and Doug home,” Bowersox said. “We’d like to get them home some time in August.”

Bowersox is a former astronaut, who flew on five shuttle missions. He recently took over as acting head of NASA’s human spaceflight division after the previous administrator, Doug Loverro, suddenly resigned. That change in leadership took place just days before Hurley and Behnken took flight. Industry sources say Loverro’s departure had to do with him breaking agency rules during a competition to procure bids for NASA’s upcoming lunar lander program.

While the timing was suspect, the Demo-2 mission was unaffected and went off without a hitch.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners

Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.

Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.

That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.


Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.


Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”

There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.

Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds

Tesla’s Roadster comes in Performance, Thrust and Rocket versions, with a claimed 0-60 under 0.59 seconds.

Tesla finally showed the next generation Roadster on Thursday night, and the demo had more in common with a SpaceX test than a track lap. At an event outside Waco, Texas, near SpaceX’s McGregor site, the car used a mix of fans and cold gas thrusters to drive up a curved ramp until it was upside down, then flew off, flipped and landed on the pavement. “Well, it worked,” Elon Musk said. “Flying cars are real.”

The Roadster also hovered itself over a Cybercab, Cybertruck, Tesla Semi, Model Y and Model 3 while moving, and that Tesla showed it going 0 to 60 mph in one second. Musk said “this will be the actual car that’s on the roads” and that it “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. He called the result a collaboration between Tesla and SpaceX engineers that is “better than any James Bond car,” with Franz von Holzhausen and Lars Moravy on site.

Tesla published new mind-blowing stats for the car that replace the previous targets. The Performance version is road ready and seats two, with active aerodynamics and a multi-mode suction system, and Tesla lists 0 to 60 mph in under 1.6 seconds. The Thrust version is race ready, also seats two, and adds rear-mounted cold gas thrusters for a 0 to 60 time of under 0.9 seconds. The Rocket version is described as air ready, seats one, and uses perimeter-mounted thrusters for forward and upward acceleration plus lateral rotational movement.

Configuration Seats 0 to 60 mph
Performance 2 under 1.6 s
Thrust 2 under 0.9 s
Rocket 1 under 0.59 s

Tesla’s own description: “So…yes, it can fly.” It lists a 0 to 60 time of under 0.59 seconds for Rocket, a top speed of up to more than 230 mph, and range of more than 300 miles. Tesla has not yet given pricing in the information we have seen, but has reopened $50,000 reservations in the newly updated Tesla Roadster configurator. Production is planned for Giga Texas in 2027 or 2028, and Musk has said it would follow the demo by 12 to 18 months.

Tesla’s Roadster page adds more on how the car works. A multi-mode fan and ground sealing system pulls air from under the car, producing enough suction to hold it upside down even when stationary. Active wings, steer-by-wire with a yoke, and a Track Mode that lowers the car round out the driving setup. The cold gas thrusters use all-electric actuators for micro adjustments to stabilize the car in flight. Tesla says it cut weight with magnesium, titanium and carbon fiber, manual controls and a fixed seat position, and the exterior has hidden headlights, a full-length taillight and Ano White paint inspired by aerospace coatings. Inside are an Ultrawhite interior with gray microsuede, a center touchscreen and two smaller forward displays, and gold tinted glass modeled on spacesuit visors. Availability is tiered: Performance is by reservation, Thrust is a limited release, and Rocket is invite only. Tesla notes the car is not approved for public road use, and that Rocket is not available in all regions.

Tesla Roadster Highlights

  • Road use: Tesla notes the car is not approved for public road use, and that Rocket isn’t available in all regions.

Musk has described the Roadster as “the best of the last of the human-driven cars,” and he has been open that it is a halo product. He said he is “not sure it moves the needle massively from a revenue standpoint,” and has warned that anyone whose top priority is safety should not buy it. Tesla reports third quarter earnings on October 21.

Amazon shuts out Elon Musk’s Grok Bot so he may just build his own rival store

Musk promises SpaceX will cover Grok Bot purchase errors, tells users to shop beyond Amazon.

Elon Musk said SpaceX will reimburse users if Grok Bot botches a purchase or leaks their card details. A few hours later he was telling users to take their shopping elsewhere after Amazon shut the agent out.

The first post was a reply to an X user who said Grok Bot booked him a flight after he sent a photo of his credit card. “This works well,” Musk wrote. “If Grok @Bot makes a mistake with a purchase or leaks your card (never happened yet), SpaceX will make you whole,” said Musk.

The second came after another user posted the error his Grok Bot hit on Amazon: “Continued access by an unauthorized AI agent violates Amazon’s Conditions of Use, to which our customers have agreed.” The user said his bots can no longer order from the site. Musk answered, “Just ask Grok @Bot to buy what you want someplace else and get a better deal. There are far more purchasing websites than just Amazon!” He later added, “Maybe we should start a competitor to Amazon,” a possible hint at an X shopping service.

The Amazon block did not start Thursday. A reply to Musk on October 10 said Amazon was blocking the bot, and Musk responded that Grok would find another way, then showed an order it placed on Lego’s website.

The latest reimbursement promise builds on late August when Musk told a Tesla investor weighing whether to give Grok Bot access to his bank accounts, “If Grok Bot messes up, we will make you whole,” as Teslarati covered when SpaceXAI added its Finance integration. That promise goes further than the company’s consumer terms, which make users responsible for what their agents do and generally cap liability at the greater of fees paid or $100. Neither Thursday post says those terms have changed, so for now it remains a statement on X rather than a published policy.

The two posts matter to Tesla owners because Grok Bot is no longer limited to a phone. Tesla brought it into its vehicles on September 22, and it is now enabled across every Cybercab and the rest of the Model Y Robotaxi fleet, as noted when Teslarati looked at why Grok Bot may be the Cybercab’s real advantage. A rider who asks for groceries or a coffee order is relying on retailers that let the agent in. Amazon has now said it will not, and Musk’s answer is to route around it.

Amazon has not commented publicly on the block in the posts Teslarati reviewed, and it is unclear whether Musk will follow through on a rival store.

So, how many of you do the vast majority of shopping on Amazon and hate that you do? Comment and let us know your thoughts!
