Early on Saturday morning, SpaceX Crew Dragon ‘Endeavour’ (capsule C206) – carrying four international astronauts – flawlessly docked with the International Space Station (ISS) for the second time in less than a year.

Capping off a smooth 24 hours of free-flight following an equally successful Falcon 9 launch on Friday, April 23rd, Dragon’s third crewed space station arrival was captured in spectacular fashion – thanks in part to the presence of a separate Crew Dragon vehicle already docked to the orbiting outpost. Recently swapped between the two ISS docking ports capable of supporting Dragons, Crew-1 NASA astronaut Mike Hopkins had – by far – the best view in the house of Crew-2’s space station rendezvous while looking out the window of the other Crew Dragon on orbit.

Former NASA flight director and Space Shuttle program manager Wayne Hale put it best, stating that SpaceX “[made] it look easy” with a “perfectly successful [Crew-2] launch and docking” – the company’s third astronaut launch and space station rendezvous since May 2020.

After a mere three days of delays – one for weather – from an April 20th (4/20) target set almost three months earlier, Crew Dragon lifted off on SpaceX and NASA’s Crew-2 mission shortly before dawn on April 23rd. As the rocket rapidly carried Dragon and its passengers from sea level to dozens of kilometers above the Earth’s surface, it sailed into sunlight, producing a spectacle that stretched across a vast swath of the pre-dawn sky as the sun lit up Falcon 9’s second stage exhaust plume.

The four astronauts aboard the flight-proven Dragon were equally amazed as the inky black vacuum outside their spacecraft’s windows turned to blinding, unfiltered sunlight. One spectacle and a flawless trip into orbit on Falcon 9 behind them, French European Space Agency (ESA) astronaut Thomas Pesquet caught a glimpse of the rocket’s expended second stage effectively flying in formation a few miles below Crew Dragon.

After almost exactly 24 hours on its own and five major Draco thruster orbit-raising and trajectory-matching burns, as well as an unwelcome collision avoidance warning that ultimately turned out to be a false alarm, Crew Dragon capsule C206 completed its second space station docking without delay around 5am on April 24th. Pesquet has published several dozen excellent photos of the flight and docking, offering the best look yet at what life aboard a free-flying Dragon is really like for the four astronauts packed into a volume – as he himself notes – roughly equivalent to a large car’s cabin.

With its successful arrival, SpaceX – for the first time ever – had two separate Crew Dragon spacecraft docked to ISS simultaneously, marking the first of at least two more Dragon ‘hand-off’ milestones to come. Though NASA nominally planned to have Commercial Crew providers SpaceX and Boeing essentially take turns on operational astronaut ferry missions, the latter company’s Starliner spacecraft is more than a year and a half behind schedule and is unlikely to perform its first crewed demonstration flight before Q1 2022.

In other words, SpaceX has been forced to mature its Crew Dragon program much faster than expected to complete at least four back-to-back astronaut launches in ~17 months, while NASA is effectively dependent on the company to ensure the ISS remains fully crewed from May 2020 to sometime in 2022.

Following Crew-2’s smooth arrival, Crew-1’s Crew Dragon and its four-astronaut crew will return to Earth as early as April 28th. Sometime in October or November 2021, SpaceX will repeat that hand-off process once again when it launches Crew-3 and recovers Crew-2. There is a distant chance Boeing will have completed two successful test flights and be ready for Starliner’s operational astronaut launch debut in early 2022, but it’s arguably much more likely that SpaceX will also perform a third hand-off between Crew-3 and Crew-4 sometime in Q2 2022 before finally handing over the reins to Starliner.

Tesla launches Powerwall Lease for affordable home backup

Published

on

Credit: Tesla

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.

Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.

The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla announces 100k Powerwalls are participating in Virtual Power Plants

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.

Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.

The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.

Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk teases Tesla Roadster unveiling once again

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor

Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.

Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”

The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.

SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
