Mars’ invisible auroras come to life in new NASA animation

Published

on

The sky on Mars has a wind of ultraviolet light that pulses as it moves across the red planet. This phenomenon is similar to Earth’s aurora borealis events, lasting from sunset until midnight, and NASA has created a new animation using data obtained from an instrument on the MAVEN spacecraft to demonstrate what it might look like to future astronauts in orbit. That is, it’s what they would see if it wasn’t invisible to the naked human eye.

“The ultraviolet glow comes mostly from an altitude of about 70 kilometers (approximately 40 miles), with the brightest spot about a thousand kilometers (approximately 600 miles) across, and is as bright in the ultraviolet as Earth’s northern lights,” explained Zac Milby, a researcher at the University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP).

Milby is one of several other LASP scientists that published a recent study on the ‘nightglow’ data in the journal JGR Space Physics. The team analyzed two Martian years’ worth of images taken by the Imaging Ultraviolet Spectrograph (IUVS) on the Mars Atmosphere and Volatile Evolution (MAVEN) mission spacecraft to find the reported wind and UV emission behavior. “The MAVEN spacecraft orbiting Mars has obtained a new type of imaging data which reveals the effects of global‐scale winds and waves in the upper atmosphere,” the study’s Plain Language Summary details.

With a mission to Mars in the near-term travel plans for both NASA and SpaceX, learning as much as possible about the planet’s atmosphere is essential. Preparations for both on-site scientific study and astronaut safety will need to incorporate the Martian ground conditions, so studies like this one provide very important and relevant data. The recent findings also demonstrate the importance of cooperative international efforts in exploring deep space, namely because MAVEN wasn’t the first spacecraft to demonstrate the existence of the ‘nightglow’ phenomenon. Rather, the European Space Agency’s Mars Express orbiter mission revealed it in 2003, leading the path for follow up and further study.

It may also be interesting to note that although Mars-based astronauts may not be able to see the UV aurora-type nightglow with their normal eyesight, instruments could likely come into play to overcome such limitations. We already have commercially available UV cameras on Earth, for instance. There’s even a UV camera smartphone add-on that one could see being used on Mars to watch the glow show in a similar fashion to augmented reality starfinders on the market.

Of course, much more science-oriented UV cameras would likely accompany any travelers to the planet, but it’s fun to imagine what may be available to more tourist-types or even Martian colonists some day.

Tesla Model Y L gets suspension complaints in over odd issue China

Published

The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.

However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.

Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.

Tesla Model Y L is gaining momentum in China’s premium segment

Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.

There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.

Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.

Tesla Cybercab event gains steam ahead of massive launch

Published

Tesla is starting to truly tease and hype its groundbreaking Cybercab event, which takes place tomorrow in Austin, Texas. It will be the first time members of the public will be able to ride in a Cybercab, a vehicle without any manual controls, on public roads.

Tesla has been dropping some hype on X over the past several days, but this morning, the excitement has truly started to build up for the event. Although Cybercab has been unveiled before, this is truly Tesla’s announcement that it is ready to start offering autonomous rides for public passengers in its new ride-hailing-geared vehicle for the first time.

The hype has started with a variety of different social media posts that are a true indication that Tesla is preparing for something big. Teasing so much of the potential of Cybercab, including its ability to truly revolutionize how people hail rides for local travel, is what the big idea for the event entails. The time that many Tesla owners, fans, and investors have been waiting for is potentially here:

The event has remained slim on details. Even invitees are still awaiting true details about what the event will entail, where they’ll go, and what is in store for the evening. This is pretty typical for an event run by Tesla; they keep things under wraps for the most part until the very last minute.

However, there is no secret about what the real intention of Tesla is for this event: it is going to be a huge reveal party for a vehicle that has no steering wheel and no pedals. It is a truly massive step for the company moving forward.

Speculation persists as to whether this is going to be an event that simply announces that rides will begin with the Cybercab, or it will be something more substantial. Tesla has said in the past that they plan to sell the Cybercab to the general public in what could become a great way to earn passive income by adding it to a more global fleet of Robotaxi-geared vehicles.

Tomorrow, the show begins in Austin, and the Cybercab goes live at some capacity; we just don’t know exactly how quite yet.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
