Less than a month after the complete loss of customer payload due to an in-flight anomaly, Rocket Lab has announced that it is ready to return its small-class Electron rocket to flight. Company CEO, Peter Beck, during a media briefing Friday (July 31) said that the Electron second-stage “re-entered the atmosphere and burned up” resulting in a failed July 4 launch of the Electron and complete loss the customer payload of seven small satellites. Beck went on to state that through a collaborative investigation with the Federal Aviation Administration Rocket Lab was “able to quickly reconstruct what happened and the AIB board (Accident Investigation Board) was able to confidently narrow down the issue to a single electrical connection.”

The thirteenth flight of the Electron carried seven small satellites, all Earth-imaging inspiring the “Pics Or It Didn’t Happen” mission name. The rocket initially experienced a flawless launch from the company’s Launch Complex-1A on New Zealand’s Mahia Penninsula and everything seemed like it was going to plan until the video feed cut out unexpectedly shortly after the nominal ignition of the second-stage which was intended to carry the payloads to orbit.

The launch was completely event free during the first-stage ascent, stage separation, second stage ignition, and payload fairing jettison, then trouble occurred. Beck stated that the electrical connection that went bad during the second-stage of the flight was “incredibly unusual because it was able to evade all of the pre-flight acceptance testing.” Beck went on to explain that “while all of the testing showed no issues, after a period of time one of the joints had high resistance and that high resistance led to heating. That heating then led to thermal expansion of one of the components. That thermal expansion and heating enabled some of the potting components – that are around that joint to keep it secure from vibration – to flow.”

Once the potting compound used to secure electrical connections was able to heat up and essentially melt – or began to flow – the electrical connection become unsecured and led to the interruption in electrical current throughout the second-stage. Beck stated that “when the video stops (in the webcast) is exactly the point (of failure).” Although the video cut out, Rocket Lab ground stations continued to receive telemetry data of the flight’s progress due to the amount of redundancy with the systems aboard Electron “telemetry is the only way you can reconstruct this stuff so we have a very high priority of those (data) channels” Beck said.

With the immense amount of data that was received during the flight and throughout the second-stage shutdown Rocket Lab was able to quickly determine the cause of the error and perform tests to determine exactly what occurred during the failed flight. “The vehicle as it flies every flight has just a huge amount of instrumentation. That coupled with a graceful shutdown coupled with full telemetry stream throughout the whole anomaly, we were really able to quickly reconstruct what happened” Beck said.

The vast amount of data and the ability to sufficiently replicate the incident now means that Rocket Lab has a plan of action in place to mitigate any failures – of this nature – on future missions. “We can actually mitigate (the anomaly) very easily through a slight change in production processes, but more importantly we can screen for it in our current vehicles and stock through more in-depth testing procedures.”

To that end, the Rocket Lab Electron is set to return to flight in August, an impeccable turn around time following an anomaly investigation.”I’m very proud of the way the team has been able to identify this issue and rectify it so quickly” Beck said. He gave high praise to the entire Rocket Lab team for relentlessly working toward determining, not only the cause of the anomaly but working toward a solution for a quick return to flight. “Literally ten minutes after we saw some anomalous behavior during the flight, the team already started to work it and they haven’t stopped. They’ve been relentless” Beck said.

The customer payload that will fly aboard the return to flight and fourteenth mission of Electron launch is expected to be announced very soon. Rocket Lab did state that following a successful launch from the LC-1A complex in New Zealand, the following mission would be the first to take place from the brand new Launch Complex 2 located at the Mid-Atlantic Regional Spaceport at NASA Wallops in Virginia. Although an American private company, Rocket Lab predominately launches from New Zealand. The upcoming mission will be the first Electron flight to occur from American soil.

Beck closed the media briefing by stating that Rocket Lab looks forward to returning to operational status and launching Electrons every month, if not bi-weekly. He expressed that Rocket Lab is looking to the future and hopes to achieve a full recovery effort of the first stage booster via a helicopter and a specially designed grappling hook with the seventeenth flight of Electron. He also hinted that “there’ll be a couple of other little surprises as well, as we execute some other programs that have been cooking up in the background.”

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

Published

on

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

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.
