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 appears to have teased a long-awaited Model Y trim for a launch on Friday.

The company posted it with its Europe & Middle East account, and it appears to be a Model Y Performance, which has been spotted testing at the famed Nurburgring in Germany.

The Model Y Performance became a big-time hit after it packed the family-style interior with lightning-fast acceleration, speed, and handling.

As Tesla transitioned the Model Y into the updated “Juniper” design, the company took its time to create an even better vehicle with the new Performance configuration.

It has surely taken its time, but the vehicle appears to have undergone some exterior changes to enhance aerodynamics, handling, and overall performance.

We recently went into what was different about the test units spotted at Nurburgring in an article, but we’ll also list them here:

  • New 21″ wheels
  • All black headliner, a big change that was included in the Model Y L, the first time a Model Y has had that option
  • Updated brakes
  • Bucket seats that appear to be similar to the new Model Y L in China
  • New Carbon Fiber Spoiler
  • Performance Badging
  • Changes to both the front and rear bumper
  • Suspension with Adaptive Dampers

Tesla Model Y Performance zips around Nurburgring with new features

It does not seem like there’s much else it could be, but it is important to note that Tesla has been developing a handful of affordable models. There is a possibility that Tesla could launch one of these on Friday, but it seems unlikely.

The affordable models will likely be coming to the United States or China before they would in Europe.

They would be developed at Gigafactory Texas or Gigafactory Shanghai. The company stated in its Q2 Earnings Shareholder Deck that it had continued to expand its vehicle offerings and successfully manufactured the first builds of a more affordable model in June.

Volume production is planned for the second half of 2025.

SpaceX Starship Flight 10 was so successful, it’s breaking the anti-Musk narrative

That’s all the proof one could need about the undeniable success of Starship Flight 10.

Starship Flight 10 was a huge success for SpaceX. When both the Super Heavy booster and the Starship Upper Stage successfully landed on their designated splashdown zones, the space community was celebrating.

The largest and most powerful rocket in the world had successfully completed its tenth test flight. And this time around, there were no rapid unscheduled disassemblies during the mission.

As per SpaceX in a statement following Flight 10, “every major objective was met, providing critical data to inform designs of the next generation Starship and Super Heavy.” The private space enterprise also stated that Flight 10 provided valuable data by stressing the limits of Starship’s capabilities.

With all of Flight 10’s mission objectives met, one would think that it would be pretty easy to cover the story of Starship’s successful tenth test flight. But that’s where one would be wrong, because Elon Musk companies, whether it be Tesla or SpaceX or xAI, tend to attract negative slant from mainstream media outlets.

This was in full force with Starship Flight 10’s coverage. Take the BBC’s Facebook post about the fight test, which read “Elon Musk’s giant rocket, earmarked for use in a 2027 mission to the Moon, has had multiple catastrophic failures in previous launches.” CNN was more direct with its slant, writing “SpaceX’s troubled Starship prototype pulls off successful flight after months of explosive mishaps” on its headline.

While some media outlets evidently adopted a negative slant towards Starship’s Flight 10 results, several other media sources actually published surprisingly positive articles about the successful test flight. The most notable of which is arguably the New York Times, which featured a headline that read “SpaceX’s Giant Mars Rocket Completes Nearly Flawless Test Flight.” Fox News also ran with a notably positive headline that read “SpaceX succeeds at third Starship test flight attempt after multiple scrubs.”

Having covered Elon Musk-related companies for the better part of a decade now, I have learned that mainstream coverage of any of his companies tends to be sprinkled with varying degrees of negative slant. The reasons behind this may never be fully explained, but it is just the way things are. This is why, when milestones such as Starship’s Flight 10 actually happen and mainstream media coverage becomes somewhat objective, I can’t help but be amazed. 

After all, it takes one heck of a company led by one heck of a leader to force objectivity on an entity that has proven subjective over the years. And that, if any, is all the proof one could need about the undeniable success of Starship Flight 10.

Tesla’s Elon Musk takes another shot at Waymo’s capabilities stemming from LiDAR

“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation.”

Tesla CEO Elon Musk has frequently expressed his opinions on LiDAR in the past, but in recent days, the EV maker’s frontman has continued to discuss the weaknesses in the technology and why his company has relied on cameras.

He also mentioned the suite’s limits on Waymo’s capabilities.

Tesla completely abandoned using radar alongside its camera suite a few years ago, something it referred to as “Tesla Vision” at the time. For its vehicles, it has only used cameras since this transition, and Musk has never once shied away from this strategy.

Earlier this week, he discussed the reliance of LiDAR and radar by other companies:

“Lidar and radar reduce safety due to sensor contention. If lidars/radars disagree with cameras, which one wins?

This sensor ambiguity causes increased, not decreased, risk. That’s why Waymos can’t drive on highways.

We turned off radars in Teslas to increase safety. Cameras ftw.”

Elon Musk argues lidar and radar make self driving cars more dangerous

He continued with this narrative again and mentioned Waymo specifically on a second occasion.

Musk’s focus this time was on Waymo vehicles and their capabilities in adverse weather, specifically snow, rain, or even dust storms, and how LiDAR struggles to navigate in these conditions.

He said:

“LiDAR also does not work well in snow, rain or dust due to reflection scatter. That’s why Waymos stop working in any heavy precipitation. As I have said many times, there is a role for LiDAR in some circumstances and I personally oversaw the development of LiDAR for the SpaceX Dragon docking with Space Station. I am well aware of its strengths and weaknesses.”

Tesla’s approach is significantly different than most companies. Waymo, Motional, Aurora, and Zoox all use LiDAR for their self-driving programs, while Tesla continues to rely on its camera-only approach.

Musk even said that Model S and Model X utilized a Tesla-developed high-resolution radar, but it could not “compare to passive optical (cameras), so we turned it off.”
