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

Published

on

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.

SpaceX reached an incredible milestone with its Starlink program with a launch last night, as the 3,000th satellite of the year was launched into low Earth orbit.

On Monday, SpaceX also achieved its 32nd flight with a single Falcon 9 rocket from NASA’s Kennedy Space Center.

The mission was Starlink 6-92, and it utilized the Falcon 9 B1067 for the 32nd time this year, the most-used Falcon booster. The flight delivered SpaceX’s 3000th Starlink satellite of the year, a massive achievement.

There were 29 Starlink satellites launched and deployed into LEO during this particular mission:

SpaceX has a current goal of certifying its Falcon boosters for 40 missions apiece, according to Spaceflight Now.

The flight was the 350th orbital launch from the nearby SLC-40, and the 3,000 satellites that have been successfully launched this year continue to contribute to the company’s goal of having 12,000 satellites contributing to global internet coverage.

There are over five million users of Starlink, the latest data shows.

Following the launch and stage separation, the Falcon 9 booster completed its mission with a perfect landing on the ‘Just Read the Instructions’ droneship.

Tesla expanded its new Full Self-Driving program, which gives people the opportunity to experience the company’s suite, in Europe.

Tesla recently launched an opportunity for Europeans to experience Full Self-Driving, not in their personal vehicles, but through a new ride-along program that initially launched in Italy, France, and Germany back in late November.

People could experience it by booking a reservation with a local Tesla showroom, but timeslots quickly filled up, making it difficult to keep up with demand. Tesla expanded the program and offered some additional times, but it also had its sights set on getting the program out to new markets.

It finally achieved that on December 9, as it launched rides in Denmark and Switzerland, adding the fourth and fifth countries to the program.

Tesla confirmed the arrival of the program to Denmark and Switzerland on X:

The program, while a major contributor to Tesla’s butts in seats strategy, is truly another way for the company to leverage its fans in an effort to work through the regulatory hurdles it is facing in Europe.

Tesla has faced significant red tape in the region, and although it has tested the FSD suite and been able to launch this ride-along program, it is still having some tremendous issues convincing regulatory agencies to allow it to give it to customers.

CEO Elon Musk has worked with regulators, but admitted the process has been “insanely painful.”

The most recent development with FSD and its potential use in Europe dealt with the Dutch approval authority, known as the RDW.

Tesla says Europe could finally get FSD in 2026, and Dutch regulator RDW is key

Tesla said it believes some regulations are “outdated and rules-based,” which makes the suite ineligible for use in the European jurisdiction.

The RDW is working with Tesla to gain approval sometime early next year, but there are no guarantees. However, Tesla’s angle with the ride-along program seems to be that if it can push consumers to experience it and have a positive time, it should be easier for it to gain its footing across Europe with regulatory agencies.

Tesla is ramping up hiring for positions related to the Roadster program, the company’s ultra-fast supercar that has been teased to potentially hover by CEO Elon Musk.

The company seems to be crossing off its last handful of things before it plans to unveil the vehicle on April Fool’s Day, just about four months away.

Tesla published three new positions for the Roadster this week, relating to Battery Manufacturing, General Manufacturing, and Vision Engineering. All three are located in Northern California, with two being at the Fremont Factory and the other at the company’s Engineering HQ in Palo Alto.

Technical Program Manager, Battery Manufacturing

Located in Fremont, this role specifically caters to the design of the Roadster to factory operations. It appears this role will mostly have to do with developing and engineering the Roadster’s battery pack and establishing the production processes for it:

“You will foster collaboration across design engineering, manufacturing, quality, facilities, and production to align with company priorities. Additionally, you will understand project opportunities, challenges, and dependencies; translate scattered information into concise, complete messages; and communicate them to every team member. As the business process development lead, you will develop, maintain, and implement tools and processes to accelerate battery manufacturing execution, achieve cross-functional alignment, and deliver highly efficient systems.”

Manufacturing Engineer, Roadster

Also located in Fremont, this role also has to deal with the concept development and launch of battery manufacturing equipment. Tesla says:

“In this role, you will take large-scale manufacturing systems for new battery products and architectures from the early concept development stage through equipment launch, optimization, and handover to local operations teams.”

Manufacturing Vision Engineer, Battery Vision

This position is in Palo Alto at Tesla’s Engineering Headquarters, and requires the design and scale of advanced inspection and control systems to next-generation battery products:

“You’ll work on automation processes that directly improve battery performance, quality, and cost, collaborating with world-class engineers in a fast-paced, hands-on environment.”

Developing and deploying 2D and 3D vision and measurement systems from proof-of-concept to deployment on high-volume battery manufacturing lines is part of the job description.

Roadster Unveiling

Tesla plans to unveil the Roadster on April 1, and although it was planned for late this year, it is nice to see the company put out a definitive date.

Musk said on the Joe Rogan Experience Podcast in late October:

“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveil ever.”

Production should begin between 12 to 18 months after unveiling, so we could see it sometime in 2027.
