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, April 2019

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 Cybertruck RWD production in full swing at Giga Texas

Videos of several freshly produced Cybertruck LR RWD units were shared on social media platform X.

It appears that Tesla is indeed ramping the production of the Cybertruck Long Range Rear Wheel Drive (LR RWD), the most affordable variant of the brutalist all-electric pickup truck.

Videos of several freshly produced Cybertruck LR RWD units were shared on social media platform X.

Giga Texas Footage

As per longtime Tesla watcher Joe Tegtmeyer, Giga, Texas, was a hotbed of activity when he conducted his recent drone flyover. Apart from what seemed to be Cybercab castings being gathered in the complex, a good number of Cybertruck LR RWD units could also be seen in the facility’s staging area. The Cybertruck LR RWD units are quite easy to spot since they are not equipped with the motorized tonneau cover that is standard on the Cybertruck AWD and Cyberbeast.

The presence of the Cybertruck LR RWD units in Giga Texas’ staging area suggests that Tesla is ramping the production of the base all-electric pickup truck. This bodes well for the vehicle, which is still premium priced despite missing a good number of features that are standard in the Cybertruck AWD and Cyberbeast.

Cybertruck Long Range RWD Specs

The Cybertruck LR RWD is priced at $69,990 before incentives, making it $10,000 more affordable than the Cybertruck AWD. For its price, the Cybertruck Long Range RWD offers a range of 350 miles per charge if equipped with its 18” standard Wheels. It can also add up to 147 miles of range in 15 minutes using a Tesla Supercharger.

Much of the cost-cutting measures taken by Tesla are evident in the cabin of the Cybertruck LR RWD. This could be seen in its textile seats, standard console, seven-speaker audio system with no active noise cancellation, and lack of a 9.4” second-row display. It is also missing the motorized tonneau cover, the 2x 120V and 1x 240V power outlets on the bed, and the 2x 120V power outlets in the cabin. It is also equipped with an adaptive coil spring suspension instead of the adaptive air suspension in the Cybertruck AWD and Cyberbeast.

Tesla preps for a Cybercab takeover of the Robotaxi platform after pilot program

Tesla looks to be preparing the Cybercab for Robotaxi operation as castings pile up at Gigafactory Texas.

Tesla is evidently preparing for the Cybercab to take over the Robotaxi platform after the pilot program in Austin, Texas, is launched.

That claim is made based on new drone footage from Gigafactory Texas captured by Joe Tegtmeyer, who found hundreds of Cybercab castings that have accumulated on property in Austin.

The Cybercab is Tesla’s dedicated Robotaxi vehicle that was unveiled last October. It features just two seats and is minimalistic, aimed toward allowing the Full Self-Driving suite to chauffeur passengers from Point A to Point B without ever having to deal with human interaction or any responsibilities within the vehicle.

In June, Tesla plans to launch its first Robotaxi rides in Texas. Although employees in Austin and in the Bay Area of San Francisco have already had access to over 1,500 trips and 15,000 miles of autonomous (but supervised) travel, Tesla plans to launch a driverless version in a limited fashion in June.

However, this initial pilot program, while presumably operating on an Unsupervised version of the FSD, will only utilize Model Ys, at least at first.

The drone footage captured by Tegtmeyer today seems to tell a story of a quick transition to the Cybercab for the Robotaxi responsibilities, especially as Tesla gets its feet wet with the early Unsupervised FSD rides and gains confidence in the fleet’s ability to navigate passengers:

It appears that between 400 and 500 Cybercab castings can be seen in the images Joe captured, a very respectable number considering the company said it will not launch the Robotaxi with the initial rides it gives in Austin.

The images seem to paint a picture that Tesla is truly ready to get things moving in terms of the Cybercab project. While it does not plan to use the vehicle initially, its manufacturing efforts for the car are being prepared by stacking these castings so they’re ready to be expanded upon into the real thing.

On the most recent Earnings Call, Tesla’s VP of Vehicle Engineering, Lars Moravy, said the Cybercab’s engineering has progressed over the last several months to “derisk things like corrosion, the ceiling across the seams of the vehicle, and when you marry several components,” and even things like early crash testing have already taken place.

Moravy continued, “As with all that combined, we kind of go into the builds that we have in this quarter for the Cybercab product, and that’s the next real big test of full-scale integration with the unboxed process. And that’s kind of where we are. So you’ll see them on the test roads in a couple of months.”

Tesla Semi futuristic sci-fi acceleration sound will never get old

Videos that capture the Semi moving at speed are most notable due to their sheer cool factor.

The Tesla Semi is not yet in mass production, but the company has accumulated over 7.9 million miles across its test fleet. With Tesla using the Semi for its operations, it is no surprise that sightings of the Class 8 all-electric truck have been abounding. 

These sightings from Tesla enthusiasts vary, but those that capture the the Class 8 all-electric truck moving at speed are most notable, possibly due to their sheer cool factor.

Tesla Semi’s Roar

There is something that just stands out with the Semi, particularly on the road. While the Semi does not have the Cybertruck’s brutalist, angular design, it is still very striking because it’s such a massive machine that moves far too quietly for its size. This is, of course, one of the reasons why the vehicle also becomes extra noteworthy when it fires up its electric motors and accelerates.

Take this video from Tesla Owners Silicon Valley, for example, which shows the all-electric hauler accelerating while pulling what appears to be a full load. In these situations, the Tesla Semi actually becomes audible, but unlike traditional diesel-powered truck, the Class 8 all-electric truck “roars” with its own, unique futuristic, sci-fi sound. In such situations, one could feel the Semi’s raw power, which comes from its three independent motors on its rear axles.

Tesla Semi Ramp

Tesla has been promoting the Semi quite a bit as of late, and recent reports have suggested that the company is putting in a lot of effort to prepare the vehicle for its production in Nevada. Tesla’s Careers website has gone live with over 80 Semi-related job openings recently as well, and a recent report has suggested that Tesla has ramped the Semi’s factory workers in Nevada to over 1,000 employees.

The company has even shared an update video of the Semi factory’s progress near Giga Nevada, as well as the design of the vehicle’s new logo. The Semi’s updated logo is quite interesting as it features elements from the Tesla Model 3’s first logo, which was unveiled way back in 2016.
