SpaceX Falcon 9 rocket aces first interplanetary launch

Published

on

SpaceX has aced its first operational interplanetary launch, sending NASA’s Double Asteroid Redirection Test (DART) spacecraft on its way out of the Earth-Moon system as part of the world’s first planetary defense mission.

Right on time, SpaceX’s flight-proven Falcon 9 booster lifted off at 10:21 pm PST with an expendable upper stage, new fairing, and the ~630 kg (~1400 lb) DART spacecraft in tow, reaching a nominal low Earth parking orbit about eight minutes later. Half a minute after the second stage’s first engine ‘cutoff’ (SECO-1), booster B1063 safely landed on drone ship Of Course I Still Love You (OCISLY), wrapping up its third orbital-class launch and spaceflight in twelve months.

Around 28 minutes after liftoff, Falcon 9’s orbital second stage fired up for the second and final time. In just 53 seconds, Falcon 9’s upper stage accelerated from a stable velocity (relative to Earth’s surface) of 7.5 kilometers per second (4.7 mi/s) to almost 11.1 km/s (6.9 mi/s), sending DART (and itself) from low Earth orbit (LEO) to an Earth escape trajectory that will ultimately leave them in orbit around the sun.

As the second Falcon hardware to reach interplanetary space, the upper stage will gradually passivate itself – depressurizing and safing batteries and flight termination systems as it prepares to spend the rest of its inactive life orbiting the sun. DART, on the other hand, has only just begun its mission. As previously discussed on Teslarati, DART is designed to slam into asteroid moon Dimorphos no earlier than September 2022 while traveling 6.6 km/s (4.1 mi/s).

“If DART succeeds, NASA anticipates it will be able to observe a slight 1.5% change in Dimorphos’ orbital period (how long it takes to orbit Didymos) with Earth-based telescopes. Perhaps one day – building upon DART, follow-up reconnaissance mission HERA, and other asteroid missions like Hayabusa2 and OSIRIS-REx – NASA and other space agencies will team up to develop a fleet of planetary defense spacecraft that can intentionally redirect asteroids that threaten Earth, preventing catastrophic impacts like the one that likely wiped out 75% of species and virtually all nonavian dinosaurs around 66 million years ago.”

If successful, the tiny DART spacecraft will prove that as long as an asteroid is spotted early enough, other tiny spacecraft can feasibly redirect them by slamming into them at very high speeds. In effect, if one or several space agencies or governments then decide to pursue planetary defense seriously enough, humanity – through technology, science, and cooperation – will be able to avoid the cosmic fate that’s befallen the dinosaurs and millions of other species before us. Put simply, if the dinosaurs had had a spacecraft and capability like what DART hopes to demonstrate, they could still be roaming the Earth today.

Given that CEO Elon Musk’s entire motivation for founding the company and pursuing spaceflight was to help make humanity multiplanetary and protect against mass-extinction events like those that befell the dinosaurs, it’s only fitting that SpaceX ultimately won NASA’s DART launch competition and sent the DART spacecraft on its way to Dimorphos as part of the first true planetary defense test in history.

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 all but confirms that affordable Model Y is coming Tuesday

It does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Published

Tesla has released a cryptic teaser of a product that would be announced on Tuesday, October 7, 2025. Based on the company’s hint, it does appear that the product would be the affordable Model Y that has been spotted doing road tests across the country over the past months.

Affordable Model Y sightings

Last week, news emerged that a number of key Tesla influencers visited Gigafactory Texas for a private event. These included veteran Tesla YouTubers, car reviewers, influencers on X, and even a teardown expert who provided the initial insights on how to improve the original Model 3 sedan. At the same time, an uncovered unit of the apparent affordable Model Y was posted online. The vehicle was reportedly sighted close to Giga Texas. 

The new Model Y variant had some notable changes from the standard Model Y. Its fascia seemed inspired by the Model 3 sedan instead of the Cybertruck, and its roof seemed blacked out. Overall, it looked like a simpler Model Y designed to be offered at an affordable price. 

The weekend teasers

Teasers about an upcoming product were posted by Tesla’s official account on social media platform X, though the electric vehicle maker made it a point to keep things very vague. Initially, a closeup video of what appeared to be an aero wheel was posted, though it was vague enough that some speculated that it could be Elon Musk’s long-announced HVAC system instead. 

On Sunday, another teaser video was posted featuring the headlights of a new car. This brought speculations that the new Roadster might finally be announced. Inasmuch as a new Roadster unveiling would be exciting, however, it was evident that the headlights in the new teaser were a match to the uncovered affordable Model Y unit that was spotted close to Giga Texas a few days ago. With this in mind, it does appear that October 7 would be the date when the world sees Tesla’s actual idea of what an affordable vehicle would be like.

Tesla releases cryptic teaser for something massive and it’s coming this week

On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.

Tesla has released a cryptic teaser for something massive, and it will release details on it this week. With many different projects in the works, there is a lot of speculation going on about what it could potentially be, but we have a few ideas.

On Sunday morning, Tesla released a nine-second teaser video of what appears to be either a vehicle wheel, fan, or some sort of propeller, but there are no real clues as to what it could be exactly.

It then ends with “10/7,” meaning it will announce something on October 7, which is this Tuesday:

Given that Tesla has been working on a handful of pretty notable projects that are set for unveiling at the end of this year, and there are some clues that seem to point in their direction with this short teaser video.

There are two projects that come to mind almost immediately: the Tesla Roadster is one, and the “E41” or affordable model is the other. Here’s what we know about both:

Tesla Roadster Demo Event

Tesla said earlier this year that it would have a demo event for the Roadster to unveil some new technologies and show off what it has been working on over the past few years.

There have been a lot of crazy things in the works for the Roadster, including a SpaceX package that would use cold-gas thrusters for an insane 1.1-second 0-60 MPH acceleration rate. This package was also supposed to help it hover, something CEO Elon Musk has teased for the past few years.

The Roadster was ready for release earlier this year, but after Chief Designer Franz von Holzhausen and VP of Powertrain Lars Moravy showed Musk what they had come up with, he wanted more.

Moravy said on the Ride the Lightning podcast earlier this year:

“What we had come up with exceeded what we originally planned. So, Elon was like, ‘Wow, great. Let’s do more!'”

The Roadster event was coined as “the most epic demo,” and since it was planned for the end of 2025, it is totally feasible to believe this could be it.

Tesla ‘E41’ Affordable Model

Some believe the teaser could be the official launch of Tesla’s affordable model, which Musk said earlier this year is simply a stripped down Model Y.

There have been some sightings of this vehicle in the past few weeks, including one on Friday that showed the vehicle completely uncovered for the first time:

The launch of the affordable model makes sense, especially from a timing perspective. With the $7,500 EV tax credit officially coming to a close on September 30, many are wondering how Tesla will spark growth in its deliveries. A more affordable EV would be the perfect response, and it is something that Tesla has been working on for some time.

Other Potential Ideas

There are some pretty interesting ideas as to what the teaser could be apart from the Roadster or affordable model. Some believe it could be a cooling fan for a GPU cluster, which would make sense considering Tesla’s prowess in data.

Grok also made an interesting guess, stating it could be a propeller for a secret air taxi Tesla is developing. This seems sort of our of left field.

We do know Tesla hosted a handful of influencers at Gigafactory Texas this past week, so whatever the company showed them is likely what will be unveiled on Tuesday.

Tesla Optimus is learning martial arts in new video teasing capabilities

For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet.

Tesla Optimus is learning martial arts, a new video released by CEO Elon Musk shows, a crazy development and advancement in the robotics project the company has been working on for a few years.

Optimus has been a major focus of Tesla for the past several years, especially as Musk has said he believes it will be the biggest product of all time and could be the biggest contributor to the company’s valuation.

For the past few months, Tesla has been refining its capabilities and making some serious progress on what Optimus is capable of. This morning, Musk released a new video showing Optimus learning Kung Fu, perhaps its most impressive feat yet:

The video shows Optimus working with a Kung Fu teacher, known as a Shifu, going through what appears to be some sort of routine of combinations. It’s quite impressive to see the fluidity of the movements and Optimus’s ability to keep up with Shifu.

Tesla has been “working hard” to scale Optimus production, Musk said last week, a project that has obviously confronted both AI and manufacturing teams with a variety of challenges.

The plan is to have an annual production run-rate of one million units by 2030, and there were plans to build 5,000 units this year.

Elon Musk gives update on Tesla Optimus progress

Musk still believes Optimus will make up roughly 80 percent of Tesla’s value. In January, he said it would be “overwhelmingly the value of the company.”

Tesla plans to launch the Gen 3 version of Optimus soon, and although a video of a new-look prototype was released by Marc Benioff, the CEO of Salesforce, the company’s frontman stated that this was not what the next-generation prototype would look like.

Elon Musk confirms Tesla has never shown Optimus V3 design yet

This video seems to show there is still significant progress being made on the Optimus project, and it will be perhaps one of the most impressive humanoid robots available to consumers in the coming years.
