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’s biggest test yet arrives this week and it’s not a rocket launch

Published

on

By

SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.

The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.

Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.

SpaceX scores another massive Pentagon deal to support military satellites

Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.

The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.

As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

SpaceX’s Starship just got filmed by its own cargo

SpaceX released new footage of Starship in space captured by the Starlink satellites it deployed.

Published

By

SpaceX released a new video Friday evening showing Starship from an angle showcased by its own Starlink satellites, watching the rocket drift away in orbit.

The 65 second clip, posted on X, stitches together footage from four cameras mounted on a single Starlink V3 satellite. It opens with a close view of Starship’s 171 foot upper stage, still catching sunlight, then pulls back as the two spacecraft separate.

The footage comes from Starship’s 13th flight test, which launched July 24 from Starbase after a scrubbed attempt and an abort caused by an engine issue the week before. When Flight 13 finally flew, it carried the first batch of functional Starlink V3 satellites Starship has ever deployed, twenty of them, with six equipped with cameras meant to scan the ship’s heat shield during reentry.

Flight 13 checked most of its boxes. Starship deployed all 20 satellites, relit a Raptor engine in space, and splashed down softly in the Indian Ocean off Western Australia. Musk’s longer term plan calls for a Starlink V3 constellation of 100,000 satellites, according to a recent FCC filing, with Starship as the only vehicle capable of launching them at the volume that requires. Each Starship flight is designed to carry up to 60 V3 satellites once the vehicle reaches routine service, well beyond what Falcon 9 can carry in a single mission.

Starship is next expected to fly with an attempt at catching the ship itself with the launch tower’s mechanical arms, a maneuver SpaceX has so far reserved for the Super Heavy booster.

Tesla flexed the new features of the Model Y L with a dedicated media event at the company’s Diner on Santa Monica Boulevard in Los Angeles.

The Model Y L is the extended-wheelbase version of the all-electric crossover, which has been voted the best-selling car in the world on three occasions. The vehicle is already rolling off production lines at Gigafactory Texas, and first deliveries are slated to take place later this year.

Tesla brings Model Y L ‘Launch Series’ to the U.S. at $61,990

Teslarati was invited to the event, but due to some scheduling conflicts, we could not make it to Los Angeles. Instead, we will have our hands on a media unit sometime in August, so we’ll be able to spend some more extended time with the Model Y L.

However, plenty of those who made it to LA shared some cool features that set the Model Y L apart from the Model Y.

Multi-Row Climate Control

Tesla fitted the Model Y L with full climate control on all three rows on the front screen. It can be adjusted by selecting which row you’d like to modify on the right-hand side of the touch screen:

Better Rear Window Visibility

One of the strangest things about the Model Y, especially the Juniper iteration, is the rear window has extremely limited visibility when looking into the rearview mirror.

Tesla has improved upon this with the Model Y L:

PowerShare will be included

Model Y L will come with PowerShare in North America, with an 11.5kW output to your home. Tesla said it would require Powerwall 3 for operation.

Wireless Charging Pad

There has been some speculation that Tesla would upgrade the wireless charging pads in the United States, but this is not the case.

Tesla owner fixes common feature complaint with crafty DIY retrofit

Tesla confirmed that it does not come with the cooled pads as the Y L in China does. This is because North America has not adopted Qi charging yet.

Thermal Management Improvements

These improvements in the Model Y L were seen with thermal management:

  • Up to 15% faster cabin cooling
  • +23% thermal efficiency gained in hot weather, 7 miles of real-world range gained
  • 8x more solar energy reflection off of glass roof
  • 30% reduction in solar energy entering the cabin

Demand

Tesla said the Model Y L is almost sold out in the U.S. It comes with
