If everything goes as planned, SpaceX’s next 60-satellite Starlink launch will soon push the Falcon rocket family to the halfway point of its ambitious reusability design goals.

SpaceX has scheduled its sixth launch of 60 Starlink satellites no earlier than (NET) 9:42 am EDT (13:42 UTC) March 14th. Known as Starlink L6 or Starlink V1 L5 (referring to the fifth batch of upgraded v1.0 satellites), the Starlink mission will be the SpaceX’s fourth this year – a cadence that would enable up to 21 Starlink launches in 2020 alone. In other words, a successful launch this weekend would put SpaceX firmly on track to realize the repeated guidance that it would attempt 20-24 Starlink missions this year.

Given that SpaceX’s annual record stands at 21 launches and that the company has many additional non-Starlink launches planned for 2020, it’s always been clear that rocket reusability would be essential to even begin to approach the launch rates Starlink demands. Doing so without severely impacting customer missions – almost certainly an unacceptable tradeoff for SpaceX – is even more of a challenge. Thankfully, with its very next launch, SpaceX is about to push the rocket reusability envelope yet again, hopefully proving that the Falcon family is halfway to realizing its design goals.

SpaceX’s final iteration of the Falcon launch vehicle – known as its Block 5 upgrade – flew for the first time in May 2018 and has performed another 27 missions in 22 months since. When it debuted, SpaceX CEO Elon Musk spoke in depth about the Block 5 upgrade and the significant changes it introduced, stating that it primarily focused on improving reliability and reusability. Notably, every single Falcon 9 Block 5 rocket produced from then on would be virtually identical to the select few boosters destined to launch astronauts, meaning that all future SpaceX launches would directly benefit from the changes NASA required.

However, arguably the biggest public focus of Block 5 upgrade would be the upgrades it brought for SpaceX’s reusable rocketry program, with Musk describing it as a cumulative product of half a decade spent attempting to land rocket boosters. The big claim: Falcon Block 5 boosters would theoretically be capable of at least ten launches apiece with minimal to no repairs in between. After reaching 10-launch milestones, Musk further noted that boosters could potentially use periodical overhauls – much like modern aircraft – to achieve 100 or more launches apiece before retirement.

Eleven months after SpaceX launched and landed the same rocket for the third time, Falcon 9 booster B1048 became the first to complete four launches and landings, placing the first 60 Starlink v1.0 satellites in orbit in November 2019. Less than two months later, Falcon 9 B1049 matched its predecessor’s record, becoming the second booster to launch four times.

Now, according to Next Spaceflight, pathfinder Falcon 9 booster B1048 is scheduled to launch for the fifth time in support of Starlink L6 – a bit less than four months after it became the first SpaceX rocket to cross the fourth-flight milestone. Just days ago, SpaceX President and COO Gwynne Shotwell revealed that Falcon boosters might never need to fly more than ten times. Given that Falcon 9 Block 5 boosters were first and foremost designed to launch no less than ten times each, B1048 is now on the brink of reaching the halfway point of one SpaceX’s most ambitious Block 5 design goals.

If B1048 (and B1049 shortly after that) can prove that Falcon boosters can successfully launch five times, it’s hard to imagine any technical showstoppers that could prevent SpaceX from achieving its self-imposed ten-flight milestone. With SpaceX likely to attempt anywhere from 10-20 more Starlink launches this year, there will be no shortage of opportunities for Falcon 9 to continue pushing the envelope of reusability.

Tune in around 15 minutes before liftoff to catch SpaceX’s Starlink L6 launch live this Saturday, pending a successful Falcon 9 static fire test later today.

Tesla’s newest feature lets you floor it out of a Supercharger while plugged in

Tesla’s new Emergency Drive Away feature lets owners flee a Supercharger while still plugged in.

Published

By

Tesla has given drivers a way to escape while a vehicle is plugged-in at a Supercharger, in the event of an emergency. The company’s charging team announced a new feature on X called Emergency Drive Away, which lets a driver shift into Drive and pull away while the charging cable is still connected to the car.

Until now, a Tesla would not leave Park with a charge cable plugged in. Drivers had to release the latch from the touchscreen, the Tesla app, or the button on the charge handle, then wait for the port to let go. Emergency Drive Away removes that lockout, but Tesla is clear that it comes at a cost. “Use of this feature will damage your vehicle and the Supercharger,” the company wrote, adding that the function is meant for emergencies only and that deliberate misuse will lead to “additional penalties.” Tesla did not say what those penalties are.


The in-car prompt is just as direct, with the warning reading: “Driving with the cable connected will cause damage to your vehicle and the Supercharger. Short camera recordings will be shared with Tesla.” That footage gives Tesla a way to separate a real emergency from someone who simply did not want to wait for the latch.

The feature requires software update 2026.38.3, and Tesla said in replies to owners that it works at every Supercharger in the United States without new stall hardware. Model S and Model X vehicles built before 2021 are not supported, and the company says the feature applies to U.S. Superchargers “for now,” leaving Canada and other markets out at launch.

Tesla Supercharger argument leads to tragic shooting incident

Tesla did not tie the announcement to any specific event, but it arrives two months after a gunman opened fire at an In-N-Out in Twin Falls, Idaho, on August 1, targeting three people in two Teslas at the neighboring Supercharger. One of them, a 66 year old man from Salt Lake City, was killed. Superchargers have been the scene of violence before, including a fatal shooting at a station near Denver in 2023.

In the weeks after Twin Falls, owners pushed Tesla for a native way to escape a stall, and many pointed back to EVject, the aftermarket breakaway connector Tesla sued in 2024 over claims it lacked overtemperature protection. The two companies later reached an agreement that led EVject to recall its earlier connectors in favor of a version with thermal sensors.

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 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.
