NASA Leans Into Solar Eclipse With 3 Rocket Launches: Here’s What’s Up With That

The space agency isn’t letting today’s solar eclipse go to waste.

We’re just hours away from North America’s last total solar eclipse until 2044, and as we prepare to look to the sky, NASA is preparing to launch three rockets.

Before, during and after the eclipse on Monday, NASA will fire three sounding rockets to determine how the total eclipse could affect radio communications on Earth. The findings could pave the way for NASA to develop new technologies to protect radio communications during both brief and extended periods when solar behavior disrupts particles on Earth.

Stargazers from Mexico to the US and Canada are standing by for the last total solar eclipse to pass over the contiguous US for the next 20 years. The duration of totality, or the time during which the moon completely shrouds the sun from view, will last 4 minutes and 27 seconds. The eclipse will reach Texas at approximately 1:10 p.m. ET and Maine by 2:22 p.m. ET. By 4:17 p.m. ET, it will move beyond the eastern North American border.

Firing rockets during an eclipse may sound like it comes straight from a sci-fi movie, but it’s a technique that’s been used for years to measure scientific data and theories. Indeed, eclipses provide critical, if short-lived, opportunities for scientists to gather information on a variety of topic areas to test whether their concepts are accurate.

Arguably the most important finding during an eclipse occurred in May 1919, when scientists discovered during a total eclipse that some stars appeared to be in the wrong place, according to NASA. The finding provided critical evidence to support Albert Einstein’s theory of relativity and the idea that the sun or other large celestial objects have so much gravity that they can bend light and distort spacetime.

NASA’s rocket launches on Monday won’t necessarily have that same gravitas, but science works in increments. The launches will be streamed live, so you can see what happens. Here’s how.

Why is NASA firing rockets during the eclipse?

The space agency is firing three sounding rockets, or rockets carrying scientific instruments, into the ionosphere, the region of the Earth’s atmosphere between the lower atmosphere, where we live, and space.

The ionosphere is scientifically important because it’s made up of particles that become ionized, or electrically charged, when they interact with the sun’s radiation. According to NASA, the ionosphere thins at night and thickens when the sun’s rays are hitting it. The ionosphere can be unpredictable, since it’s highly sensitive to disruption.

«Earth’s terrestrial weather and space weather can impact these particles, making it a dynamic region and difficult to know what the ionosphere will be like at a given time,» NASA says.

Another thing: the ionosphere affects communication, and especially high-frequency communication like radio waves. That could, for instance, create disturbances in communications with pilots in the air or with government agencies doing research. But radio waves traveling to and from satellites aren’t just of concern to aviators and scientists. They’re also vital elements of daily life, from satellite internet services like SpaceX’s Starlink to the GPS signals that underlie all manner of financial transactions and that help you get where you’re going.

From a site in Virginia, NASA’s three rockets will be launched into the ionosphere 45 minutes apart: before the eclipse starts; when the eclipse is ongoing; and after the eclipse has reached its peak. The rockets will reach a maximum altitude of 260 miles, allowing them to spend plenty of time in the ionosphere, which spans 55 miles to 310 miles above the Earth’s surface.

Each of the rockets is carrying four two-liter soda bottle-sized instruments that will be ejected during flight to evaluate any ionosphere disturbances, or perturbations, during the eclipse.

«Gathering the data on these perturbations will help scientists validate and improve current models that help predict potential disturbances to our communications, especially high frequency communication,» NASA says.

Has NASA fired rockets at an eclipse before?

This isn’t the first time NASA has fired rockets during an eclipse. In October, NASA fired the same three rockets from its White Sands Test Facility in North Mexico during an annular solar eclipse. The agency said that it was able to recover the rockets and refurbish them, allowing them to be used in Monday’s mission.

Thanks to that mission, scientists were able to see ionosphere disturbances after it fired the second and third rockets, during and after the eclipse, respectively. NASA didn’t see any ionosphere disturbance during the first launch.

However, this time around, the rockets are equipped with additional instruments, allowing them to capture more information than they did last year, NASA says.

When is NASA firing its rockets?

NASA plans to launch all three rockets from its Wallops Island facility in Virginia. The first rocket will launch at approximately 2:40 p.m. ET, with the second rocket launching at approximately 3:25 p.m. ET. NASA plans to launch the final rocket by 4:05 p.m. ET.

As always, timing on the launches depends on a variety of factors, including on-the-ground conditions, and may be subject to change. But since the eclipse isn’t waiting for NASA to be ready to fire rockets, expect the space agency to try to keep a tight schedule to ensure it doesn’t miss its window to capture data.

How can I watch NASA fire rockets at the eclipse?

If you’re interested in watching NASA’s rocket-firing mission, the agency will livestream it from its official Wallops Island YouTube page. It’ll also be featured during NASA’s official solar eclipse broadcast

The rocket-only livestream will begin at 2:30 p.m. ET. NASA will start airing its solar eclipse coverage at 1 p.m. ET.

Ring Finally Goes Wire-Free for Its Latest 4K Video Doorbells

The launch of battery-powered versions of the company’s powerful AI doorbells has been highly anticipated.

Security company Ring on Wednesday announced a significant expansion of its video doorbell line, notably battery-powered versions of both its 4K and 2K models, priced from $80.

Both Amazon’s Ring and Google Nest debuted high-resolution video doorbells with new AI features in the fall of 2025. But they were wired only, and in my tests, I kept thinking, «I sure wish there were battery models available.»

Wireless video doorbells are far better for most front doors than models that require connecting to your existing doorbell wiring, which is often poorly positioned for a security camera. Mine, for example, is located on a wall beside my door that’s useless for any kind of video views, no matter how you angle a lens.

«Enhancing image quality in battery-powered doorbells means customers can enjoy reliable performance with the flexibility to install devices in a way that suits their space, whether renting or living in homes without existing wiring,» a Ring spokesperson said.

At first, I wondered whether the higher 4K resolutions and more advanced AI features would use too much power to support batteries. If so, Ring is the first to fix that issue with this suite of doorbells, including these models available for preorder right now:

Ring Battery Doorbell Pro — $250: This model offers up to 4K resolution and 10x zoom, and Ring says it features a redesigned internal architecture to support battery power.
Ring Battery Doorbell Plus (2nd-gen) — $180: This model includes a quick-release battery pack along with 2K video.
Ring Battery Doorbell (2nd-gen) — $100: This video doorbell includes 2K video, a 6x zoom and what Ring calls a «streamlined, rechargeable design,» which means you take the entire video doorbell to charge it, not just the battery — a design I greatly prefer, since Ring’s battery packs can get fiddly.

There’s also a new version of a Ring wired doorbell with 2K resolution, starting at $80. It wouldn’t be Ring without a plethora of doorbell devices to confuse newcomers, which is why I have a guide specifically for Ring video doorbells that will need some updating once I finish testing these new models.

Resolution plus an intelligence upgrade

Ring’s ordinary subscriptions of the Ring Protect plan give you cloud video storage and intelligent alerts for people, packages and vehicles, which are important but not really advanced AI. But spring for the $20-per-month Ring AI Pro cam, and this new generation of cameras opens up other capabilities.

Ring’s AI features include AI video descriptions, so if you get an alert, you can also get a summary of what the doorbell saw, including people and activities. A similar feature lets you search your video history with specific terms, such as «bike,» «truck» and so on. You also get the beta version of Ring’s Familiar Faces feature, which can ID logged faces of people who approach.

If these AI features make you uneasy and you’d rather protect your privacy, the best option is to avoid a subscription altogether or choose a lower-tier plan that gives you cloud storage without AI.

I also have a guide on how to turn off Ring’s detection and data-sharing features that might make you nervous, so you can keep what you like while ditching what you don’t.

McDonald’s KPop Demon Hunter Meals Include Bright Purple Nugget Sauce

The Derpy McFlurry mixes popping boba pearls and berry sauce into a soft-serve dessert.

McDonald’s has seen success with themed combo meals, including its holiday Grinch Meal. Now, the fast-food chain is capitalizing on Netflix’s Oscar-winning animated film, KPop Demon Hunters, with new upcoming menu items and both a breakfast meal and a lunch/dinner offering. Let’s hope you like the color purple.

The HUNTR/X Meal, named for the K-pop girl group in the movie, is a 10-piece chicken McNuggets meal that includes a medium drink and three special menu items.

Ramyeon McShaker fries come with a small bag of soy, garlic, sesame and spice seasoning, along with regular McDonald’s french fries. You sprinkle the seasoning into the provided bag, dump in the fries, shake it all up and eat.

The meal includes two new sauces for the fries and nuggets. Hunter sauce is a sweet chili sauce mixing notes of chili, garlic and pepper. But my favorite item on this new menu is Demon sauce, a bold mustard sauce with some heat and a bold purple color. There’s just not enough dark purple food out there.

There’s also a new dessert, the Derpy McFlurry, which blends creamy vanilla soft serve with berry-flavored popping boba pearls, served with a swirl of wild berry sauce. McDonald’s named it for the supernatural feline, Derpy Tiger, from the movie.

If breakfast is your bag, the new morning meal is the Saja Boys Breakfast Meal, named for the movie’s boy band.

It includes a Spicy Saja McMuffin sandwich, which is a sausage McMuffin with egg and a spicy Saja sauce, hash browns and a small drink.

Both meals come with a photocard for one of the bands and a Derpy card. The Derpy card includes a QR code you can scan to unlock online content about the film.

The full KPop Demon Hunters menu should be available at participating McDonald’s beginning March 31.

The McDonald’s Grinch meal (and its accompanying patterned socks) sold out quickly, so KPop Demon Hunters fans may want to mark their calendars and nab a meal when they are released.
