SpaceX’s Falcon Heavy flies a complex mission for the Air Force in launch video

Published

on

SpaceX has gone to unique lengths for the third launch of its Falcon Heavy rocket and made an exhaustive webpage dedicated to the mission, reviewing its importance to SpaceX and the United States and discussing most of its 23 manifested spacecraft.

Known as the US Air Force’s Space Test Program 2 (STP-2) mission, Falcon Heavy Flight 3 will be a critical pathfinder for the US military’s systematic utilization of both Falcon Heavy and its flight-proven boosters.

The STP-2 mission will be among the most challenging launches in SpaceX history with four separate upper-stage engine burns, three separate deployment orbits, a final propulsive passivation maneuver and a total mission duration of over six hours. [It] will demonstrate the capabilities of the Falcon Heavy launch vehicle and provide critical data supporting certification for future National Security Space Launch (NSSL) missions. In addition, [the USAF] will use this mission as a pathfinder for the [military’s systematic utilization of flight-proven] launch vehicle boosters.

SpaceX offers a very effective summary of the various challenges presented by Falcon Heavy’s STP-2 mission and third launch. It’s as challenging as it is for one very specific and largely artificial reason. All the way back in 2012, the USAF contracted the launch to give SpaceX a low-risk opportunity to demonstrate specific capabilities the military branch requires before they certify a given rocket to launch high-value payloads. Originally intended to fly STP-2 in mid-2015, Falcon Heavy suffered almost five years of delays during its development, caused by a combination of unexpected technical difficulties and two catastrophic Falcon 9 failures in 2015 and 2016.

After spending the whole of 2017 gradually catching up on delayed customer launches, SpaceX successfully conducted Falcon Heavy’s launch debut on February 6th, 2018. Four months later, the Air Force announced that it had completed the SpaceX rocket’s preliminary certification and awarded the company a $130M launch contract for AFSPC-52, a classified military satellite. According to documents describing the mission, the satellite weighs approximately 6350 kg (~14,000 lb) and needs to be placed into a geostationary transfer orbit (GTO) measuring 35,188km X 185km (21,850 mi X 115 mi).

Conveniently, Falcon Heavy’s commercial launch debut saw the massive rocket deliver the communications satellite Arabsat 6A – weighing ~6450 kg (~14,200 lb) – into an extremely high GTO, almost 90,000 km X 330 km (56,000 mi X 205 mi). In simpler terms, Falcon Heavy Flight 2 was an almost perfect demonstration that SpaceX is more than capable of successfully launching AFSPC-52, a milestone that could come as early as H2 2020.

The STP-2 mission should help to boost the US military’s confidence in Falcon Heavy even further. The mission is comprised of 23 separate satellites from a dozen or so different groups, ranging from a NOAA weather satellite constellation to a NASA-built atomic clock. The purpose of such a varied range of payloads is to have SpaceX’s Falcon upper stage (S2) place three separate sets into three distinctly different Earth orbits, a challenge that will require the rocket to ignite its Merlin Vacuum engine four times and survive in space for more than six hours.

SpaceX has been testing this critical long-coast technology since at least February 2018, when Falcon Heavy’s debut included a six-hour coast of the upper stage to send a Tesla Roadster on an Earth escape trajectory. SpaceX completed that test successfully and said Roadster is now orbiting the sun on a trajectory that regularly reaches beyond the orbit of Mars. SpaceX has continued to test the longevity of its universal Falcon upper stage, including a handful of on-orbit demonstrations after completing customer missions.

SpaceX will reuse the Falcon Heavy side boosters seen above on the USAF’s STP-2 mission.

Aside from opening the door for new areas of competition in military launch procurement, successfully proving the long-coast capabilities of the Falcon upper stage will also mean that SpaceX can offer them commercially. Military launches often require long coasts in order to get spacecraft to their operating orbits as quickly as possible, typically involving an upper stage burning at the top of a transfer orbit to circularize said orbit. This capability can also be of significant value to non-government customers, however, as the faster a satellite can get to its operational orbit, the faster its owner can start using it to generate revenue. Traditionally, most commercial geostationary communications satellites are sent to transfer orbits, raising one end of the orbit (apogee) but leaving the low end (perigee) in low Earth orbit. Satellites then use their own propulsion systems to circularize their orbits before they can begin commercial operations.

It’s safe to assume that SpaceX is interested in commercially offering services like those above to make Falcon Heavy even more competitive with the likes of ULA’s Atlas/Delta/Vulcan rockets and Arianespace’s Ariane 5 and Ariane 6. The US military will almost certainly be the anchor customer, but a reliable upper stage with long-coast capabilities may one day allow Falcon Heavy to routinely launch commercial satellites directly into circular orbits or send flagship NASA spacecraft into deep space. But first, STP-2. According to Taiwan space agency NSPO, involved in the mission through their Formosat-7 constellation (also known as NOAA’s COSMIC-2), Falcon Heavy could launch STP-2 as early as June 22nd.

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

on

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.
