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 adds a new feature to Navigation in preparation for a new vehicle

After CEO Elon Musk announced earlier this week that the Semi’s mass production processes were scheduled for later this year, the company has been making various preparations as it nears manufacturing.

Tesla has added a new feature to its Navigation and Supercharger Map in preparation for a new vehicle to hit the road: the Semi.

After CEO Elon Musk announced earlier this week that the Semi’s mass production processes were scheduled for later this year, the company has been making various preparations as it nears manufacturing.

Elon Musk confirms Tesla Semi will enter high-volume production this year

One of those changes has been the newly-released information regarding trim levels, as well as reports that Tesla has started to reach out to customers regarding pricing information for those trims.

Now, Tesla has made an additional bit of information available to the public in the form of locations of Megachargers, the infrastructure that will be responsible for charging the Semi and other all-electric Class 8 vehicles that hit the road.

Tesla made the announcement on the social media platform X:

Although it is a minor development, it is a major indication that Tesla is preparing for the Semi to head toward mass production, something the company has been hinting at for several years.

Nevertheless, this, along with the other information that was released this week, points toward a significant stride in Tesla’s progress in the Semi project.

Now that the company has also worked toward completion of the dedicated manufacturing plant in Sparks, Nevada, there are more signs than ever that the vehicle is finally ready to be built and delivered to customers outside of the pilot program that has been in operation for several years.

For now, the Megachargers are going to be situated on the West Coast, with a heavy emphasis on routes like I-5 and I-10. This strategy prioritizes major highways and logistics hubs where freight traffic is heaviest, ensuring coverage for both cross-country and regional hauls.

California and Texas are slated to have the most initially, with 17 and 19 sites, respectively. As the program continues to grow, Florida, Georgia, Illinois, Washington, New York, and Nevada will have Megacharger locations as well.

For now, the Megachargers are available in Lathrop, California, and Sparks, Nevada, both of which have ties to Tesla. The former is the location of the Megafactory, and Sparks is where both the Tesla Gigafactory and Semifactory are located.

Tesla stock gets latest synopsis from Jim Cramer: ‘It’s actually a robotics company’

“Turns out it’s actually a robotics and Cybercab company, and I want to buy, buy, buy. Yes, Tesla’s the paper that turned into scissors in one session,” Cramer said.

Tesla stock (NASDAQ: TSLA) got its latest synopsis from Wall Street analyst Jim Cramer, who finally realized something that many fans of the company have known all along: it’s not a car company. Instead, it’s a robotics company.

In a recent note that was released after Tesla reported Earnings in late January, Cramer seemed to recognize that the underwhelming financials and overall performance of the automotive division were not representative of the current state of affairs.

Instead, we’re seeing a company transition itself away from its early identity, essentially evolving like a caterpillar into a butterfly.

The narrative of the Earnings Call was simple: We’re not a car company, at least not from a birds-eye view. We’re an AI and Robotics company, and we are transitioning to this quicker than most people realize.

Tesla stock gets another analysis from Jim Cramer, and investors will like it

Tesla’s Q4 Earnings Call featured plenty of analysis from CEO Elon Musk and others, and some of the more minor details of the call were even indicative of a company that is moving toward AI instead of its cars. For example, the Model S and Model X will be no more after Q2, as Musk said that they serve relatively no purpose for the future.

Instead, Tesla is shifting its focus to the vehicles catered for autonomy and its Robotaxi and self-driving efforts.

Cramer recognizes this:

“…we got results from Tesla, which actually beat numbers, but nobody cares about the numbers here, as electric vehicles are the past. And according to CEO Elon Musk, the future of this company comes down to Cybercabs and humanoid robots. Stock fell more than 3% the next day. That may be because their capital expenditures budget was higher than expected, or maybe people wanted more details from the new businesses. At this point, I think Musk acolytes might be more excited about SpaceX, which is planning to come public later this year.”

He continued, highlighting the company’s true transition away from vehicles to its Cybercab, Optimus, and AI ambitions:

“I know it’s hard to believe how quickly this market can change its attitude. Last night, I heard a disastrous car company speak. Turns out it’s actually a robotics and Cybercab company, and I want to buy, buy, buy. Yes, Tesla’s the paper that turned into scissors in one session. I didn’t like it as a car company. Boy, I love it as a Cybercab and humanoid robot juggernaut. Call me a buyer and give me five robots while I’m at it.”

Cramer’s narrative seems to fit that of the most bullish Tesla investors. Anyone who is labeled a “permabull” has been echoing a similar sentiment over the past several years: Tesla is not a car company any longer.

Instead, the true focus is on the future and the potential that AI and Robotics bring to the company. It is truly difficult to put Tesla shares in the same group as companies like Ford, General Motors, and others.

Tesla shares are down less than half a percent at the time of publishing, trading at $423.69.

SpaceX secures win as US labor board drops oversight case

The NLRB confirmed that it no longer has jurisdiction over SpaceX.

SpaceX scored a legal victory after the National Labor Relations Board (NLRB) decided to dismiss a case which accused the company of terminating engineers who were involved in an open letter against founder Elon Musk. 

The NLRB confirmed that it no longer has jurisdiction over SpaceX. The update was initially shared by Bloomberg News, which cited a letter about the matter it reportedly reviewed.

In a letter to the former employees’ lawyers, the labor board stated that the affected employees were under the jurisdiction of the National Mediation Board (NMB), not the NLRB. As a result, the labor board stated that it was dismissing the case.

As per Danielle Pierce, a regional director of the agency, “the National Labor Relations Board lacks jurisdiction over the Employer and, therefore, I am dismissing your charge.”

The NMB typically oversees airlines and railroads. The NLRB, on the other hand, covers most private-sector employers, as well as manufacturers such as Boeing. 

The former SpaceX engineers have argued that the private space company did not belong under the NMB’s jurisdiction because SpaceX only offers services to “hand-picked customers.” 

In an opinion, however, the NMB stated that SpaceX was under its jurisdiction because “space transport includes air travel” to get to outer space. The mediation board also noted that anyone can contact SpaceX to secure its services.

SpaceX had previously challenged the NLRB’s authority in court, arguing that the agency’s structure was unconstitutional. Jennifer Abruzzo, the NLRB general counsel under former United States President Joe Biden, rejected SpaceX’s claims. Following Abruzzo’s termination under the Trump administration, however, SpaceX asked the labor board to reconsider its arguments.

SpaceX is not the only company that has challenged the constitutionality of the NLRB. Since SpaceX filed its legal challenge against the agency in 2024, other high-profile companies have followed suit. These include Amazon, which has filed similar cases that are now pending.
