While the mission is not done just yet, SpaceX is days away from (hopefully) wrapping up an extraordinarily smooth debut of its newest spacecraft, a human-rated vehicle known as Crew Dragon. Assuming no anomalous behavior during reentry, descent, and landing this Friday, SpaceX will likely be less than six months away from launching its first astronauts to the International Space Station (ISS), the most important step yet towards offering reliable and routine transport to Earth orbit and ultimately between Earth and Mars. 

Founded by Elon Musk to kickstart a stagnant space industry and drive humanity to become an interplanetary species, SpaceX is in the process of building the first full-scale prototype(s) of the launch vehicle (Super Heavy) and spacecraft (Starship) it believes will deliver on those promises. Along with countless programmatic and technical lessons learned, every conceivable aspect of Crew Dragon’s development will feed directly into SpaceX’s development of Starship, meant to one day safely transport and land as many as 100 passengers on the surface of Mars.

A spacefaring civilization, one step at a time

In the process of building Crew Dragon, SpaceX has been forced to become rising experts in fields like human-rated environmental control and life support systems (ECLSS), as well as ensuring an even more extreme level of redundancy and reliability compared with SpaceX’s already high standards for their uncrewed Falcon rockets and Cargo Dragon spacecraft. 

  • More so than any particular piece of technology present on Crew Dragon, the process of both cooperating and grappling with NASA to build the spacecraft to high standards and ‘certify’ it has hopefully had an extremely positive impact on SpaceX’s own engineers and company-wide standards, albeit potentially at the cost of some of the willingness to take risks and move quickly. 

“I’m personally convinced that this has made, certainly, SpaceX better, to have NASA guide us, and to look at requirements, and to try to question requirements, and what’s the true reason behind those requirements, and then basically comply with the overall safety culture that NASA taught us, I would say, to some extent. And so I feel like it certainly made a better SpaceX and made better engineers out of the SpaceX engineers. And I really appreciate that very much.”

-Hans Koenigsman, Vice President of Mission Assurance, SpaceX

  • Regardless, the end result will ultimately be a reliable spacecraft capable of transporting an average of 4-7 astronauts to and from the ISS, whether that end result is the result of near-perfect execution the first time around or discovering and fixing problems during flight tests. 
    • Compared to NASA, SpaceX prefers a radically agile approach to development, meaning that the company will rapidly build, test, and fly iterations of the same hardware of software, beginning with the minimum viable product and ending (although improvement never really ends) with an advanced solution optimized by extensive lessons learned. 
  • Through the process of building Crew Dragon, SpaceX has hopefully absorbed most of the valuable lessons and practices NASA can often be rich with while rejecting the unhealthy and unsuccessful tendencies that contribute to NASA’s distinctly unimpressive modern efforts to build human-rated rockets (SLS) and spacecraft (Orion, Space Shuttle).
  • With that knowledge and technical experience, SpaceX may already have an extremely strong foundation upon which it can build its next-gen spacecraft, Starship. In theory, Crew Dragon’s life support system – meant to support up to 7 astronauts with extreme reliability and safety – should be able to scale up to ECLSS fit for dozens or hundreds of passengers.
    • In a worst-case scenario relative to mass efficiency, SpaceX could quite literally package Crew Dragon’s ECLSS system into a module and duplicate it as many times as needed for a given Starship crew. Identical modules could then be transported in a cargo bay for any structures built on the surface of Mars or the Moon.
  • Understandably, Crew Dragon does not need a significant number of systems critical for longer stays in space, as it is only designed to support humans for approximately one week in free-flight. SpaceX will still need to develop extremely efficient recycling systems, used to recycle water, oxygen, and other consumables to extend the amount of time the ISS (or Starship/Mars colonies) can operate without external supply deliveries.
    • In essence, recycling technology is roughly (or sometimes exactly) equivalent to something known as in-situ resource utilization (ISRU), basically prioritizing local resources over shipped goods. A small subset of SpaceX’s future projects team has been working on ISRU – particularly Sabatier reactors for Starship refueling on Mars – for several years.
    • In late 2017, Elon Musk stated that the design and development of SpaceX’s own ISRU hardware were “pretty far along.”

Mission Updates:

  • SpaceX’s Crew Dragon spacecraft will attempt its first orbital-velocity reentry and Atlantic Ocean splashdown on the morning of Friday, March 8th.
  • The second launch of Falcon Heavy could occur as early as late March
  • Aside from DM-1 and Falcon Heavy Flight 2, it’s unclear what SpaceX mission will happen next. DM-1 may be the only SpaceX launch in March, while several missions are tentatively scheduled for April and May.

Eric Ralph is Teslarati's senior spaceflight reporter and has been covering the industry in some capacity for almost half a decade, largely spurred in 2016 by a trip to Mexico to watch Elon Musk reveal SpaceX's plans for Mars in person. Aside from spreading interest and excitement about spaceflight far and wide, his primary goal is to cover humanity's ongoing efforts to expand beyond Earth to the Moon, Mars, and elsewhere.

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

Published

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.
