NASA has published some of the first recognizable photos taken by the James Webb Space Telescope (JWST), the most capable space telescope ever created.

On December 25th, 2021, the James Webb Space Telescope launched into orbit from South America’s Kourou, French Guiana spaceport, catching a ride on a European Ariane 5 rocket. After a 30-day voyage from the launch pad to an operational orbit approximately 1 million miles from Earth; weeks of maneuvering, orienting, and deploying hundreds of mechanical parts, the telescope has finally unveiled its first images from space – including an unexpectedly recognizable view of its vast primary mirror.

The array of images show a nondescript star (HD 84406) in the constellation Ursa Major that was chosen to support JWST calibration mainly because of how dim it is. Each image is created from light reflecting from each of Webb’s 18 main mirror segments, which together make up the 6.5-meter-wide (21 ft) primary mirror of the telescope. In this instance, those images were reflected into a secondary mirror and then recorded by the Near Infrared Camera (NIRCAM). Eventually, if all goes well during the lengthy calibration and commissioning process, all 18 mirror segments will be aligned to the level of individual wavelengths of light (nanometer precision) and focused until all 18 photos of star HD 84406 become one. Finally, each of the telescopes many complex instruments must also be calibrated.

This image mosaic was created by pointing the telescope at a bright, isolated star in the constellation Ursa Major known as HD 84406. This star was chosen specifically because it is easily identifiable and not crowded by other stars of similar brightness, which helps to reduce background confusion. Each dot within the mosaic is labeled by the corresponding primary mirror segment that captured it. These initial results closely match expectations and simulations. (NASA)

Image capture operations started on February 2nd. Webb was repositioned 156 times to properly capture images of HD 84406 and after 25 hours, JWST was able to locate the star within all 18 mirror segments and generated 1,560 images using NIRCam’s 10 detectors, amounting to 54 gigabytes of raw data.

“This initial search covered an area about the size of the full Moon because the segment dots could potentially have been that spread out on the sky,” said Marshall Perrin, deputy telescope scientist for Webb and an astronomer at the Space Telescope Science Institute. “Taking so much data right on the first day required all of Webb’s science operations and data processing systems here on Earth working smoothly with the observatory in space right from the start. And we found light from all 18 segments very near the center early in that search! This is a great starting point for mirror alignment.”

Additionally, NASA shared an unexpected, ghostly “selfie” that the observatory took of its primary mirror array with a crucial instrument known as NIRCAM (short for Near-Infrared Camera).

“Moving forward, Webb’s images will only become clearer, more detail-laden, and more intricate as its other three instruments arrive at their intended cryogenic operating temperatures and begin capturing data. The first scientific images are expected to be delivered to the world in the summer of 2022. Though this is a big moment, confirming that Webb is a functional telescope, there is much ahead to be done in the coming months to prepare the observatory for full scientific operations using all four of its instruments.” (NASA)

Because Webb prioritizes weak infrared wavelengths of light to detect extraordinarily distant objects in our universe, the entire business side of the telescope – included all mirrors, sensors, and most instruments – must be kept incredibly cold – closer to absolute zero than any temperature humans are familiar with. The telescope uses a tennis-court-sized multilayer sun shield to protect itself from the heat of the sun, which it must be constantly exposed to in order to power itself with solar arrays. The outermost layer will always face the Sun and reflect most of its heat, operating at a scorching 230 degrees Fahrenheit. But each layer of the shield will become cooler and cooler so that JWST’s instruments stay cryogenic, operating around -370 degrees Fahrenheit.

The James Webb Space Telescope is the world’s largest, most powerful, and most complex space-based observatory ever built. If commissioning ends as successfully as launch, deployment, and early alignment, Webb will one day help solve mysteries of our own solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe. Webb is an international program led (and mostly funded) by NASA alongside partners ESA (European Space Agency) and CSA (Canadian Space Agency).

The Tesla Semi looks to have its newest adoptee as US Foods, the second-largest foodservice distributor in the United States, was seen with its badging on the all-electric Class 8 truck.

US Foods trails only Sysco Corporation in terms of foodservice distributors by volume in the United States. The company joined several other massive food industry entities, such as PepsiCo, and its subsidiary, Frito-Lay, have both utilized the Tesla Semi in their fleets.

Tesla Semi futuristic sci-fi acceleration sound will never get old

The Semi in question was spotted by X user Zanegler, a prominent tracker of the Tesla Semi and its factory, which sits near the company’s Gigafactory Nevada plant in Reno:

US Foods also has a distribution center in Reno, which could have something to do with its decision to start using the Semi in regional logistics.

With an influx of EV semitrucks hitting the market from many different manufacturers, it is evident that companies are taking the idea of making their fleets more environmentally friendly very seriously.

Tesla is still very close to unloading the Semi in a more volumized fashion, as the company’s Vice President of Vehicle Engineering, Lars Moravy, said in January:

“We just closed out the Semi factory roofing walls last week in Reno…but we’re prepping for mechanical installation of all the equipment in the coming months… The first builds of the high-volume Semi design come late this year in 2025 and begin ramping early in 2026.”

First Tesla Semi high-volume production builds expected this 2025

With the latest addition of US Foods, Tesla increases its list of companies that are planning or are already using the Semi to help with local logistics and transportation. Among them are:

PepsiCo
Walmart
Sysco
Costco
Martin Brower
Saia Inc.
UPS
Anheuser-Busch
DHL

Many other companies have plans to use the Semi in their fleets. Currently, Tesla appears to be hand-picking those who have access to the vehicle as the pilot program continues.

Tesla Cybertruck takes a bump from epic failing Dodge Charger

The Cybertruck seemed unharmed by the charging Charger.

There comes a time in a driver’s life when one is faced with one’s limitations. For the driver of a Dodge Charger, this time came when he lost control and crashed into a Tesla Cybertruck–an absolute epic fail.

A video of the rather unfortunate incident was shared on the r/TeslaLounge subreddit.

Charging Charger Fails

As could be seen in the video, which was posted on the subreddit by Model Y owner u/Hammer_of_something, a group of teens in a Dodge Charger decided to do some burnouts at a Tesla Supercharger. Unfortunately, the driver of the Charger failed in his burnout or donut attempt, resulting in the mopar sedan going over a curb and bumping a charging Cybertruck.

Ironically, the Dodge Charger seemed to have been parked at a Supercharger stall before its driver decided to perform the failed stunt. This suggests that the vehicle was likely ICE-ing a charging stall before it had its epic fail moment. Amusingly enough, the subreddit member noted that the Cybertruck did not seem like it took any damage at all despite its bump. The Charger, however, seemed like it ran into some trouble after crashing into the truck.

Imagine Supercharging your car, then this happens.

Luckily the owner said there was no damage to the Cybertruck, despite being hit. 🦾 pic.twitter.com/f4B0vt58Gr— Nic Cruz Patane (@niccruzpatane) May 9, 2025

Alleged Aftermath

As per the the r/TeslaLounge subreddit member, the Cybertruck owner came rushing out to his vehicle after the Dodge Charger crashed into it. The Model Y owner then sent over the full video of the incident, which clearly showed the Charger attempting a burnout, failing, and bumping into the Cybertruck. The Cybertruck owner likely appreciated the video, in part because it showed the driver of the Dodge Charger absolutely freaking out after the incident.

The Cybertruck is not an impregnable vehicle, but it can take bumps pretty well thanks to its thick stainless steel body. Based on this video, it appears that the Cybertruck can even take bumps from a charging Charger, all while chilling and charging at a Supercharger. As for the teens in the Dodge, they likely had to provide a long explanation to authorities after the incident, since the cops were called to the location.

Tesla is implementing a new AI-based strategy to improve service for owners. Service has routinely been among the biggest complaints of owners, although it has improved drastically over the past few years.

Some of the complaints that Tesla has received regarding its Service platform have evidently been used to develop new strategies to not only streamline the entire experience but also to make things easier for the company, which deals with many claims each week.

As a result of complaints in the past, Tesla has used various strategies to make things better for customers. However, the latest improvement comes as a result of AI, something Tesla leans on in many facets of its business.

Tesla adds ingenious solution to app to streamline Service appointments

Tesla’s AI and IT Infrastructure, Cybersecurity, and Vehicle Service head Raj Jegannathan said on X this week that the company is rolling out a new AI Agent specifically designed to handle service comms with customers.

He said the new Service AI Agent will detect delays in communications between the company and the customers, monitor the sentiment of these conversations, and auto-escalate certain claims directly to leaders.

It will also allow customers to type the word ‘Escalate’ in the message center portion of the phone app after two weeks of delays. This will help customers reach higher-ups more easily and likely will eliminate the complaints that many have had over the past few years.

The company is rolling out the AI Agent in ten pilot locations to start. Its first day being active was May 8.

Jegannathan said:

“Tesla Service’s new AI Agent detects comms delays, monitors sentiment, & auto-escalates to leaders. Starts tomorrow at 10 pilot locations. In 2 weeks, type “Escalate” in ‘message center’ to reach managers. Guardrails in place to prevent abuse. We’ll keep improving!”

Service has had a lot of interesting strategies used to improve things, but it has definitely been a weak point of the Tesla ownership experience. In a perfect world, vehicles wouldn’t need repair for anything, but that is not realistic.

Instead, Tesla has worked to expedite the entire Service experience through various strategies, including F1-style service, and a goal to fix two-thirds of repair claims within the same day.

Parts availability sometimes takes this goal out of reasonableness, but these constant attempts at improving the repair experience show Tesla is doing what it can to make things better for owners.
