NASA’s Parker Solar Probe takes first picture inside the Sun’s atmosphere

Published

Traveling at the record-breaking speed of 213,200 miles per hour, NASA’s Parker Solar Probe came within 15 million miles of the Sun’s surface, completing its first solar encounter phase and rewarding scientists with the first picture ever taken from within our star’s atmosphere.

Launched on August 12, 2018 in a United Launch Alliance Delta IV Heavy rocket from Cape Canaveral, Florida, the probe will help provide answers to some of the mysteries of our Sun. In particular: Why is the atmosphere hotter than the surface? Why is the solar wind continuously accelerated? These are important questions considering the Sun is both essential for life and a potential danger through its magnetized materials’ interference with our satellites, electronics, and astronauts in orbit. Scientists on the craft’s team presented the initial set of new data from its encounter on December 12th during the 2018 American Geophysical Union meeting.

The Parker Probe’s team began downloading data from its journey on December 7th this year, but the actual Sun passage took place about a month earlier, from October 31st through November 11th. The delay was caused by the nature of the Sun itself – as a wide band radio source, communications are not possible anytime a craft is in front, behind, or to the side of it.

During the probe’s approaches, scientists rely on one of four beacons installed that signal the craft’s status. Mission controllers at the John Hopkins University Applied Physics Labs (JHUAPL) received the “A” beacon at 4:46 pm EST on November 7, 2018, indicating that the probe was operating well and collecting data. Also, more data from the probe’s initial encounter will be forthcoming next year following its next approach.

This latest visitor to the Sun was named after physicist Eugene Newman Parker, best known for his mid-1950s theories about solar wind and the Sun’s atmosphere being hotter than the surface itself, and the craft will likely be one more data point complimenting his predictions. Since the Parker Probe’s mission will encounter our star in ways never done before, its science team is not quite sure of what to expect.

“Parker is an exploration mission — the potential for new discoveries is huge,” Nour Raouafi, a Parker Solar Probe project scientist at the JHUAPL in Laurel, Maryland, was quoted on the issue. The craft will also pass by Venus a total of seven times and will come within 3.8 million miles of the Sun at its closest of 24 planned approaches.

Figuring out what the actual underlying physics of the Sun are is a challenge for scientists studying its activity. When observing the surface changes, the variations seen are difficult to classify as being caused by either the star’s activity or its rotation due to how fast it moves. The speed of the Parker Probe will allow it to nearly match the Sun’s rotational speed, one revolution per 27 days as viewed from Earth, meaning it will hover over one area for a short amount of time.

While there, it will be able to specifically collect data about activity caused by the Sun itself, thereby enabling scientists to revise their models accordingly. To collect data surrounding these questions, the probe was given a thermal heat shield that can withstand the 2,500 degrees Fahrenheit temperatures it will be exposed to while maintaining a mid-80s F temperature for its instruments.

In addition to the Parker Probe’s historic photo and data, NASA has been on a roll with milestones and discoveries this year. Launched in 1977, the Voyager 2 spacecraft became the second human-made object to enter interstellar space as it left our solar system on November 5th. The first was Voyager 1 when it left on August 25, 2012. NASA also landed its InSight craft on the surface of Mars on November 26, 2018, and several photos have been returned from it since, including a lander “selfie“. That mission had a second milestone with it via two CubeSats named Mars Cube One (MarCO), successfully demonstrating the use of tiny satellites in deep space. The satellites were able to relay InSight’s landing event data to its team much quicker than would be been possible with other orbiting satellites, and they even sent back a picture of the red planet as they passed by and continued into their long orbit around the Sun.

Tesla has taken a huge step forward with its Cybercab project, as the vehicle has been spotted on the Fremont Test Track for the first time.

Typically, when cars are spotted on the Fremont Test Track, it means Tesla has begun advancing the development of that specific project. With Cybercab production slated for 2026, it seems Tesla is ready to get things moving.

The Cybercab was unveiled one year ago tomorrow, at the “We, Robot” event in Los Angeles.

Tesla has been hoping to get Cybercab production started in early 2026. With a few months until then, the program has taken some leaps, including the recent start of crash testing of the vehicle at the Fremont Factory in Northern California.

Some of these units have made their way to Gigafactory Texas at Tesla’s crash testing facility:

Now, it has taken another step as Tesla has officially started testing the vehicle at the Fremont Test Track:

However, the Cybercab being spotted marks a significant step forward for Tesla, as it indicates the company is nearing a major milestone in production, whether for deliveries or on-road testing.

It does seem as if Tesla could employ the Cybercab for its Robotaxi program in Austin, Texas, and Northern California.

With more markets expected to launch Robotaxi rides soon, it could be a formidable challenge for the new vehicle, especially if Tesla can initiate rides without a Safety Monitor.

Chevy answers Tesla’s new ‘Standard’ offerings with an actually affordable EV

Chevy answered Tesla’s new Standard Model 3 and Model Y offerings with its second-generation Bolt EV, a car that actually appeals to those who were looking for affordability.

Earlier this week, Tesla unveiled the Model 3 and Model Y Standard, two stripped-down versions of the cars of the same name it already offers. The Long Range versions are now labeled as “Premium,” while the Performance configurations stand alone.

Tesla launches two new affordable models with ‘Standard’ Model 3, Y offerings

However, many people were sort of upset with what Tesla came to market with. For well over a year, it has been transparent that it was planning to develop affordable models, and this year, it was forced to take action to counter the loss of the $7,500 EV tax credit.

The Model 3 Standard starts at $36,990, while the Model Y Standard comes in at $39,990. While these are cheaper than the company’s Premium offerings, many fans said that Tesla missed the mark with the pricing, as these numbers are not necessarily “affordable.”

At the very least, they will likely miss the mark in helping Tesla regain annual growth rates for its deliveries. Tesla will likely rely on its “unboxed process,” which will be used to manufacture the Cybercab and potentially other affordable models in the future. These will be priced at below $30,000.

Other carmakers are making their moves and were able to undercut Tesla’s new Standard offerings, Chevrolet being one of them.

This week, the company launched its second-gen Bolt EV, which starts at just $28,995.

Here are the full specs:

  • 65 kWh LFP battery
  • 255 miles of range (EPA estimated)
  • Native NACS port for Tesla Supercharger accessibility without an adapter
  • Up to 150 kW charging speed
  • Bidirectional power of 9.6 kW
  • Front-Wheel-Drive
  • 10-80% charging in just 26 minutes
  • No Apple CarPlay or Android Auto
  • SuperCruise capable
  • 11.3″ touchscreen, 11″ digital gauge cluster
  • 16 cubic feet of cargo capacity
  • Other Trims
    • RS – $32,000
    • Base LT – $28,995
  • Deliveries begin in early 2026

Let’s be frank: Tesla fans are unlikely to bat an eye at other OEM offerings. However, first-time EV buyers might be looking for something more price accessible, so vehicles under $30,000 are where they will look first, at least for most people.

If money isn’t an option, people will consider spending a minimum of $37,000 on a new vehicle, especially an EV, as a first-time owner.

The Bolt EV could be something that does well, especially considering its one of only a handful of EVs that are priced at around $30,000 brand new in the U.S.

The others are:

  • Nissan Leaf S ($28,140)
  • Mini Cooper SE ($30,900)
  • Fiat 500e ($32,500)

While these cars are priced at around $30,000 and are affordable, they each offer minimal range ratings. The Nissan Leaf S and Fiat 500e have just 149 miles, while the Mini Cooper SE has 114 miles.

Tesla Model S makes TIME’s list of Best Inventions

Published

on

Tesla’s flagship sedan, the Model S, has officially been named one of TIME Magazine’s Best Inventions of the 2000s. It joins its sibling, the Model 3, which made the list in 2017.

The Model S is among the most crucial developments in the automotive industry in the last century.

Just as the Ford Model T made its mark on passenger transportation, becoming the first combustion engine vehicle to be successfully developed and marketed at a time when horse and buggy were the preferred mode of transportation, the Model S revolutionized things a step further.

Although it was not the first EV to be developed, the Tesla Model S was the EV that put EVs on the map. In 2012, TIME recognized the Model S as a piece of technology that could truly transform the car industry.

The publication wrote:

“This electric four-door sedan has the lines of a Jaguar, the ability to zip for 265 miles (426 km) on one charge—that’s the equivalent of 89 m.p.g. (2.6 L/100 km)—and touchscreen controls for everything from GPS navigation to adjusting the suspension.”

Looking back, TIME was right on. The Tesla Model S was truly a marvel for its time, and it, along with the OG 2008 Roadster, can be seen as the first two EVs to push electrification to the mainstream.

As TIME described this year, the Model S “proved to be a game-changing experience for electric vehicles,” and it ended up truly catalyzing things for not only the industry, but Tesla as well.

The Model S acted as a fundraiser of sorts for future vehicles, just as the Model X did. They paved the way for the Model 3 and Model Y to be developed and offered by Tesla at a price point that was more acceptable and accessible to the masses.

The Current State of the Tesla Model S

The Model S contributes to a very small percentage of Tesla sales. The company groups the Model S with the Model X and Cybertruck in its quarterly releases.

Last year, that grouping sold 85,133 total units, a small percentage of the 1.789 million cars it delivered to customers in 2024.

Things looked to be changing for the Model S and the Model X this year, as Tesla teased some improvements to the two cars with a refresh. However, it was very underwhelming and only included very minor changes.

Lucid CEO shades Tesla Model S: “Nothing has changed in 12 years now”

It appeared as if Tesla was planning to sunset the two cars, and while it has not taken that stance yet, it seems more likely that the company will begin taking any potential options to heart.

CEO Elon Musk said a few years ago that the two cars were only produced due to “sentimental reasons.”
