SpaceX officially has permission to perform a Falcon 9 booster recovery after its next launch for the US Air Force, now guaranteed to be the first time a rocket booster attempts to land during an operational launch for the US military.

Alongside their booster landing attempt confirmation, the USAF Space and Missile Systems Center (SMC) also posted the first official SpaceX video of a rocket acceptance test released in almost 2.5 years, a test it says was completed just days after the GPS satellite it’s scheduled to launch arrived in Florida. The very same Falcon 9 booster was shown off in unprecedented detail just last month and now SMC says that SpaceX fired up the rocket at its McGregor, Texas development facilities for a routine static fire on February 13th. The company is currently scheduled to launch its second USAF GPS III satellite – Space Vehicle 03 (SV03) – no earlier than 7am EDT (11:00 UTC), April 29th, a target set just days ago.

With the spacecraft in Florida and factory-fresh Falcon 9 booster successfully proofed, all that remains is for SpaceX to test and deliver the mission’s Falcon upper stage and payload fairing (if it hasn’t already). After the booster – believed to be B1060 – is inspected and its tanks are cleaned, it can also be packaged and transported by road the rest of the way to SpaceX’s Florida launch facilities, setting the company up for the critical mission and historic landing attempt.

While SpaceX has technically already landed Falcon 9 and Falcon Heavy boosters after its NROL-76 and STP-2 launches for the NRO and USAF, the company only officially began operational military launches once its Falcon 9 rocket was fully certified. STP-2, for example, was effectively high-stakes make-work designed to help the USAF fully certify SpaceX’s brand new Falcon Heavy rocket to launch expensive – verging on irreplaceable – military satellites.

Its first truly operational US military launch occurred in December 2018, when Falcon 9 booster B1054 was intentionally expended in support the USAF’s inaugural GPS III launch, successfully placing the first of 10 (or 32) planned upgraded navigation satellites into orbit. It’s believed that the USAF required such extreme safety margins (extra propellant and performance) that SpaceX couldn’t even attempt booster or fairing recovery. This made B1054 the first (and hopefully only) Falcon 9 Block 5 booster to launch without even the basic hardpoints needed to attach landing legs.

Effectively confirming that B1054’s demise was was a contrivance and by no means a technical necessity, the SMC announced on February 20th that SpaceX’s GPS III SV03 mission is officially “the first time a booster is planned to land on a drone ship during a NSS [National Security Space] launch.” Effectively identical to B1054 aside from the addition of grid fins and landing legs, this means that Falcon 9 booster B1060 will be able to attempt a landing aboard a SpaceX drone ship shortly after launch.

Just like GPS III SV01 satellite launched by SpaceX in December 2018 and the GPS III SV02 satellite launched United Launch Alliance (ULA) launched in August 2019, GPS III SV03 is a more than $500 million spacecraft designed to upgrade the US GPS navigation constellation. SpaceX has already won five (of five) competitively-awarded GPS III launch contracts thanks to its Falcon 9 rocket’s exceptionally competitive pricing, meaning that there is an excellent chance the company will win many more in the near future.

GPS III SV03 is one of 10 “Block IIIA” satellites to be launched between 2018 and 2026 and will be followed by another 22 “Block IIIF” satellites to be built by Lockheed Martin for ~$330M apiece. All 26 unassigned spacecraft will need launches of their own between now and the mid-2030s, worth anywhere from $1-2.5B to SpaceX if the company performs well on all five of its first contracts and continues to crush competitor ULA on launch costs.

With the USAF already demonstrably interested in supporting Falcon booster reusability and now open to SpaceX recovering Falcon 9 boosters after moderately-challenging GPS III launches, it’s safe to say that SpaceX’s ultra-competitive pricing is here to stay.

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Published

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.
