SpaceX is hours away from its Cargo Dragon (Dragon 1) spacecraft’s last space station resupply mission, a historic launch that will also include a Falcon 9 booster’s first land landing attempt in more than half a year.

Scheduled to lift off no earlier than 11:50 pm EST (04:50 UTC) on March 6th (March 7th UTC), flight-proven Falcon 9 booster B1059 rolled out to SpaceX Launch Complex 40 (LC-40) – part of Cape Canaveral Air Force Station (CCAFS) – on Thursday afternoon. Carrying twice-flown Dragon capsule C112, set to smash SpaceX’s orbital spacecraft turnaround record, tonight’s launch will mark SpaceX’s last International Space Station (ISS) mission under its first NASA Commercial Resupply Services (CRS) contract – awarded in 2008.

Aside from Cargo Dragon’s historic final launch and record spacecraft turnaround time, CRS-20 will also mark SpaceX’s first attempted land landing – meaning a Falcon 9 booster landing at LZ-1 or LZ-2 – since July 2019. Thanks in part to SpaceX’s Starlink launch priorities and Falcon Heavy’s intermittent launch cadence, the sonic booms of Falcon booster reentries have been a relative rarity at Landing Zones for the last half-year. CRS-20 will thankfully end that faux-drought and may even be followed just weeks later by a second Falcon booster return to LZ-1.

A decade of success in orbit

Over Dragon 1’s decade of service, the spacecraft has successfully delivered more than 40 metric tons (90,000 lb) of cargo to the International Space Station (ISS) and returned almost as much from the station to Earth – still the only operational spacecraft capable of doing so since the Space Shuttle’s 2011 retirement.

If CRS-20 goes as planned, NASA will have awarded SpaceX a total of $3.1B for its finished CRS Phase 1 contract, translating to an average of $147M apiece for 21 missions (including the CRS-7 failure and Dragon’s first space station demo mission) to the ISS.

In other words, each kilogram of cargo Falcon 9 and Dragon delivered to the space station wound up costing NASA a bit less than $80,000, admittedly eye-watering but quite favorable compared to the Space Shuttle’s ~$340,000/kg (assuming program cost of $240B (c. 2020) and STS-135’s ~5300 kg of cargo).

Small steps towards full reusability

SpaceX’s CRS Phase 1 successes have also helped NASA cautiously accept flight-proven commercial rockets and spacecraft as the company has gradually introduced Falcon 9 booster and Cargo Dragon capsule reusability. Now, more than two years since SpaceX’s first capsule (June 2017) and booster reuses (December 2017) on NASA CRS missions, the company has launched two Dragon capsules to the space station for the third time and flown Dragons on flight-proven boosters four times.

CRS-20 will mark the third time a Cargo Dragon capsule (C112) flies a third orbital resupply mission, as well as the fifth time a CRS mission will launch on a flight-proven booster (B1059). Compared to the sheer scale and ambition of SpaceX’s next-generation, fully-reusable Starship and Super Heavy launch system, Dragon and Falcon 9 may seem rather diminutive. However, it’s hard to exaggerate just how much reusability expertise SpaceX has gained through their development.

A great deal of work undoubtedly remains, but SpaceX’s Dragon spacecraft and Falcon rockets are the foundation upon which Starship will (hopefully) one day succeed. (SpaceX)

Set to take over resupply missions and ferry astronauts to and from the space station, SpaceX and CEO Elon Musk already considered Dragon 2 (Crew Dragon) to be dramatically simpler, faster, and cheaper to reuse. Starship will ultimately build off those significant improvements, enabling another leap (or several) forward. Perhaps just as importantly, Falcon and Dragon reuse will likely continue to make profound political and bureaucratic inroads over the next 5-10 years, gradually eroding and reshaping the status quo. Their progress will thus hopefully set both the technical and societal stages for widespread success and acceptance by the time Starship can be declared operational.

Weather is currently 60% GO for CRS-20, and the rocket and spacecraft are likely just hours from going vertical at the LC-40 launch pad. As always, tune into SpaceX’s official webcast approximately 15 minutes before liftoff to catch the Falcon 9 launch and landing live.

Tesla Robotaxis are becoming a common sight on Austin’s public roads

Tesla Robotaxi sightings are becoming much more frequent ahead of its launch planned for this month.

Tesla Robotaxis are becoming a common sight on the public roads of Austin, Texas, as yet another test mule has been spotted near the company’s target launch date.

Just over a week ago, the first public sighting of a driverless Tesla Robotaxi was reported. The vehicle was an updated version of the Tesla Model Y, which will be the initial model used in the public deployment of the Robotaxi platform.

Throughout the past week, sightings have been more common, as people in Austin have been looking for the unique decal Tesla is placing on car doors to recognize the driverless vehicles (After all, Robotaxis are not as easy to recognize as driverless vehicles without the LIDAR unit on the roof like Waymo).

Yet another sighting of a Robotaxi was shared on social media today, just two days before CEO Elon Musk’s proposed launch date of June 22:

It is easy to tell that there is nobody in the driver’s seat of this vehicle. Tesla is using its white interior on this particular mule, making it incredibly simple to recognize that no human is controlling the car.

Whether Tesla will still meet the June 22nd deadline remains to be seen, but it is no secret that the company is prioritizing safety ahead of offering public rides.

Tesla will initially roll out the Robotaxi platform in Austin, but it has already started the regulatory process in other areas, specifically California.

The National Highway Traffic Safety Administration (NHTSA) is also helping to streamline the process for companies developing driverless vehicles by giving exemptions to automakers. It will make things much more efficient, benefiting Tesla and other car companies that have similar plans.

Tesla Robotaxi just got a big benefit from the U.S. government

Elon Musk teases Tesla Optimus Gen 3 capabilities: ‘So many improvements’

If you thought Optimus Gen 2 was impressive, Tesla might have a surprise for you.

Elon Musk has teased that huge improvements are coming to Tesla’s Optimus humanoid robot, which is arguably the product that the company is developing with the most potential for everyday use by consumers and valuation increases from a financial perspective.

Optimus is still in the development stages, but Tesla has made great strides in its development over the past several years. It started as a simple idea that was unveiled with a human being in a spandex suit.

Tesla posts Optimus’ most impressive video demonstration yet

Just a few years later, Tesla has developed several humanoid robot prototypes that have made their way to influencers and have lent a helping hand around the company’s manufacturing facilities.

Tesla has already introduced two generations of Optimus, as the most recent release featured a vast number of improvements from the initial version.

The following is a list of things Tesla improved upon with Optimus Gen 2 compared to Gen 1:

  • Tesla introduced a weight reduction of roughly 22 pounds, improving efficiency and agility
  • Optimus Gen 2 had a walking speed that improved by 30 percent over Gen 1
  • Tesla developed more capable hands that had 22 degrees of freedom, double that of Gen 1. This improved object handling
  • Optimus Gen 2 had a 2-degree-of-freedom neck, as Gen 1’s was fixed
  • Tesla integrated actuators and sensors for better performance. This includes things like foot force/torque sensing, articulated toe sections that are close to human foot geometry for better balance and movement
  • Optimus Gen 2 has 28 degrees of overall freedom, improving flexibility from the first generation
  • Tesla’s Optimus Gen 2 can do more than Gen 1, and has shown improved motor control and precision, doing things like squats, yoga poses, dancing, and even poaching an egg

These changes essentially brought Tesla closer to what will be the Optimus version that makes it to production. The company has plans to start production for the public in 2026, but some units will be manufactured for internal use within its factories as soon as this year. Tesla has said it could scale to 100,000 units or more by next year.

Musk also revealed to Teslarati recently that the company is in the process of building the production line that will bring manufacturing rates of Optimus to that level.

However, there is another design of Optimus coming, and Musk says it will feature “so many improvements”:

Tesla has said that Optimus will have the capability to perform tedious and time-consuming tasks like folding laundry, babysitting, cooking, walking the dog, and plenty of other things. However, it will be super impressive to see it do things that require true coordination, like threading a needle, for example.

Musk did not hint toward any specific developments that Tesla will aim for with Optimus Gen 3, but the sky is the limit, especially as it will be performing some manufacturing tasks across its factories.

Elon Musk slams Bloomberg’s shocking xAI cash burn claims

Musk stated that “Bloomberg is talking nonsense.”

Elon Musk has forcefully rejected Bloomberg News’ claims that his artificial intelligence startup, xAI, is hemorrhaging $1 billion monthly. 

In a post on X, Musk stated that “Bloomberg is talking nonsense.” He also acknowledged an X user’s comment that people “really have no idea what’s at stake” with AI.

Bloomberg‘s Allegations and Musk’s Rebuttal

The Bloomberg News report painted a dire picture of xAI’s finances. Citing people reportedly familiar with the matter, the news outlet claimed that xAI burns $1 billion a month as costs for building advanced AI models outpaced the company’s limited revenues. 

Bloomberg alleged that xAI is planning to spend over half of a proposed $9.3 billion fundraising haul in three months, with a projected $13 billion loss in 2025. The report also claimed that of the $14 billion that xAI has raised since 2023, only $4 billion remained by Q1 2025. Even this amount, the news outlet alleged, will be nearly depleted in Q2.

xAI did not comment on Bloomberg‘s claims, though Elon Musk shared his thoughts on the matter on social media platform X. In response to an X user who quoted the publication’s article, Musk noted that “Bloomberg is talking nonsense.” Musk, however, did not provide further details as to why the publication’s report was fallacious.

xAI’s Bright Horizon

Despite Bloomberg‘s claims, even the publication noted that xAI’s prospects are promising. The company, now merged with X, aims to leverage the platform’s vast data archives for model training, which could reduce costs compared to rivals like OpenAI. Tapping into X also allows xAI to access real-time information from users across the globe. 

xAI’s valuation reportedly soared to $80 billion by Q1 2025, up from $51 billion in 2024. The AI startup has attracted heavyweight investors such as Andreessen Horowitz, Sequoia Capital, and VY Capital so far, and optimistic projections point to profitability possibly being attained by 2027. This would be quite a feat for xAI as OpenAI, the AI startup’s biggest rival, is still looking at 2029 as the year it could become cash flow positive.
