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.

OpenAI chief Sam Altman outlines why the AI sector is urging a slowdown: risk of losing control

Sam Altman and Dario Amodei call for a measured pace in AI development, proposing safety frameworks and international coordination to avoid losing control, while U.S. and Chinese tensions underscore the urgency.

OpenAI’s Sam Altman offered the most thorough remarks to date on potential AI safety frameworks, following his alignment with Anthropic’s Dario Amodei and Elon Musk in urging a temporary slowdown of the sector. Tensions surrounding AI safety have surged after an Anthropic researcher resigned last week, claiming that developers feared the technology could “cause humanity’s demise by the end of the decade,” a warning that spurred similar alarm among OpenAI staff and other lab members. The leaders of major AI firms have recently shown uncommon agreement, as Altman and Musk jointly endorsed Amodei’s essay calling for a measured pace in advancing the most powerful AI models. AI‑related stock prices fell on Monday as investors reacted to the statements, while U.S. President Donald Trump rejected the CEOs’ caution on Sunday, arguing that a slowdown would hinder America’s dominance in AI compared with China. Sam Altman outlines two potential disastrous outcomes for AI development. Altman stated in a late‑night X post that a federal framework establishing uniform safety standards for frontier AI is welcome, emphasizing that “no level of American competitive pressure can excuse reckless behavior.” He warned that AI advancement might lead to loss of control over future outcomes and could concentrate excessive power in the hands of a single individual or corporation. At the same time, Washington legislators are rushing to respond to demands for regulatory safeguards. The developments occur as Anthropic and OpenAI prepare for what could be historic initial public offerings, with Altman stating in a Fortune interview on Saturday that the companies will not pursue an IPO in 2026. Amodei’s three‑step plan. A primary safety concern involves models gaining the capacity to enhance their own performance, a process called recursive self‑improvement (RSI). He noted that since early summer AI has been progressing rapidly, largely because AI systems are now capable of creating the next generation of AI themselves. He warned that without oversight, the technology could outpace our capacity to comprehend and control it, making careful, possibly restrained, development essential. He outlined a three‑step approach designed to slow development while preserving commercial benefits and maintaining the United States’ competitive edge in AI. The plan calls for every frontier AI company to provide external evaluators with access comparable to that of employees — a commitment Anthropic has already made — and urges all such labs to adopt shared safety standards, curb uncontrolled AI acceleration, and coordinate globally. On Saturday, Altman posted on X that he concurred with Amodei’s call for AI firms to “pace the frontier,” adding that adopting independent evaluators with employee‑level access is a worthwhile step and that his company will follow suit. Altman said in a Monday post that consistent regulations to manage frontier risk — such as independent auditors — are valuable, but clarified that “pacing” does not equate to halting progress, which remains swift and ongoing. He concluded that the costs of pacing are justified, asserting that no level of American competitive pressure can excuse reckless actions that let capabilities outpace alignment and monitoring. He noted that governmental assistance will be needed for international coordination, but emphasized that the industry should first act independently. Coordinating AI safety measures and a sector‑wide slowdown with Chinese AI developers will present significant hurdles. The United States and China continue a rivalry for AI supremacy, with tensions rising as Chinese models become increasingly sophisticated and widely adopted. He added that the toughest aspect of his proposal is the possibility that rival nations may decline to adopt similar measures. He noted that the long‑term goal would be collaborative effort to impose a speed limit on AI progress, according to an interview with CBS News’ “Sunday Morning.” He acknowledged that achieving such a limit would be challenging due to strong incentives to get ahead and the military advantages involved, admitting uncertainty about feasibility but urging an attempt. The essay has attracted criticism in China, with state‑owned Global Times stating on Monday that “Amodei’s proposals aim to cast China’s legitimate AI development as a threat and exacerbate U.S.–China confrontation.” China’s Foreign Ministry responded on Monday, labeling the CEOs’ remarks as “fearmongering.”

Novo CEO tells CNBC why drugmaker is rebranding, needs to ‘rethink’ obesity strategy

The Danish drugmaker called the changes the beginning of a new chapter for the company, which faces stiff competition from Eli Lilly.

Novo Nordisk

The Danish drugmaker called the changes the beginning of a new chapter, as it has been grappling with stiff competition from chief rival Eli Lilly

In an exclusive interview with CNBC, Novo CEO Mike Doustdar said the rebrand and culture shift are “part of the same package” for the company to evolve its strategy as it tries to win back customers from Lilly.

“I think there’s no secret that over the last four or five years, the external environment and what has happened to Novo Nordisk has really made us reflect how we need to readjust and rethink about the next decade to come and what shifts are needed in our strategic direction,” he told CNBC.

Doustdar said the “work is cut out for us,” adding that Novo needs to improve several aspects – from research and development and manufacturing to sales and marketing – to be able to compete in the obesity drug market.

Shares of Novo have dropped about 15% this year despite the successful launch of the oral version of Wegovy, which surpassed 3 million prescriptions as of June. The company recently scrapped three trials on an experimental cardiovascular drug. That challenge came as it continues to lag in the obesity space with 38.8% market share compared to Lilly’s 60.9% in the second quarter, according to a Lilly earnings presentation citing IQVIA data.

In a release, Novo also announced a broader company rebrand focused around the phrase “Lasting Health Starts Now,” which promotes the idea that patients should make progress toward long-term well-being immediately rather than later. The company said the marketing is a bid to build relevance and trust with the public and other stakeholders, and bring “breakthrough science closer to people’s daily lives.”

When asked whether the rebrand and cultural overhaul were driven by Novo’s recent market share losses in obesity, Doustdar said the changes were less about competitive setbacks and more about adapting to a dramatically different operating environment.

He said the rapid growth of obesity treatments has transformed Novo’s patient base and shifted the market toward a more consumer-oriented model, where patients move on and off therapies more frequently than in traditional diabetes care. As a result, Doustdar said Novo needs to become more focused on meeting patients where they are, while increasing the speed and clarity of its decision-making to keep pace with the evolving market.

“Our operating environment phenomenally changed compared to just 10 years ago,” he told CNBC.

Novo Nordisk will remain the legal name for the company, according to the release. That original name dates back to the 1989 merger of two competing Danish pharmaceutical companies: Novo Terapeutisk Laboratorium and Nordisk Insulinlaboratorium.

The drugmaker said its corporate culture will be based on a new set of four principles that will help it gain advantages in an increasingly competitive market where more of its products have gone direct-to-consumer.

Those tenets are innovating with patients as the primary focus, raising the company’s performance to “create greater value for all stakeholders,” setting clearer priorities and simpler workflows and never compromising on patient safety and ethics.

“When you think about strategy, that’s really the the journey you’re taking and the direction you’re setting the company to go forward with,” Doustdar said. “But you also need behaviors. You need a cultural element that allows your colleagues and yourself to really make sure that a strategy gets executed.”

Despite its challenges, Novo has had one significant tailwind this year in the launch of the oral version of Wegovy. On top of its explosive launch, the pill had a head start over a rival weight loss pill from Lilly called Foundayo.

Doustdar said Novo has maintained “a lion’s share” of the oral market even with competition, noting that physicians find the Wegovy pill to be more effective than Lilly’s, with around 17% of weight loss.

Iran Claims It Shot Down U.S. Advanced Drone Near Hormuz as Middle East Tensions Rise

Iran says it shot down an advanced U.S. drone over the Strait of Hormuz amid rising tensions and stalled diplomacy. President Trump linked the conflict to potential oil control, citing the Venezuela deal and predicting lower gas prices if the war ends.

Iran’s military announced it had shot down a sophisticated American drone above the Strait of Hormuz, marking the latest volley in a cycle of warnings and strikes between Tehran and Washington that shows no sign of easing.

The Islamic Revolutionary Guard Corps stated on Monday that its newly unveiled advanced aerospace defense system intercepted and destroyed an advanced MQ‑1 drone over the Hormuz strait, offering no further details about the drone’s mission. The MQ‑1, built by U.S. defense contractor General Atomics, has historically been flown mainly by the U.S. Air Force and the CIA.

The downing comes after a string of Iranian actions targeting U.S. unmanned naval assets in the Gulf, as the conflict, now in its seventh month, continues with little de‑escalation and diplomatic efforts over the vital waterway remain stalled.

On Sunday, President Donald Trump said the United States could keep pressing its campaign against Iran and seize control of its oil, comparing the situation to the agreement Washington reached with Venezuela earlier this year.

“We’ll ultimately get out (of the war), unless we decide to stay and keep the oil like Venezuela,” Trump remarked at the Irish Open golf championship in Ireland. He added that the revenue the U.S. gains from the Venezuela deal — which gave Washington access to about one‑fifth of Venezuela’s oil reserves — has “paid for the war many times.”

Under the August agreement, Venezuela handed over majority U.S. control of more than 65 billion barrels of oil reserves — more than twice the size of America’s own reserves — in exchange for $209 billion deposited into Venezuela’s state treasury. Secretary of State Marco Rubio said the pact would also attract roughly $100 billion in private investment to help revive the Venezuelan economy.

Trump also said on Sunday that he expects the seven‑month Iran war to conclude this year, perhaps after the November midterm elections, and insisted that gasoline prices would “drop like a rock” once the conflict ends.

He stressed that he would only accept the “right deal,” noting that Tehran has been “calling constantly” for peace talks, a claim Iran has previously rejected.

**Stalled Hormuz talks**

A planned meeting in Oman between Gulf states and Iran to discuss possible arrangements for the Strait of Hormuz — the crucial conduit for global oil and gas shipments — was postponed, Omani Foreign Minister Badr Albusaidi said on X on Sunday, citing the need for “consensus.”

Iranian and Gulf officials had been slated to meet on Monday to sign an accord establishing an Iran‑Oman shipping lane through the Strait of Hormuz, although no direct negotiations between the United States and Iran were underway at that time.

Since the war began in February, the Strait of Hormuz has been under an Iranian‑led naval blockade, later joined by U.S. forces, keeping global energy prices elevated.

A June agreement between Washington and Tehran collapsed over disagreements about the waterway, and a recent surge in attacks by Yemen’s Houthi rebels — an ally of Tehran — has given that group leverage over another key chokepoint, the Bab el‑Mandeb.

Vessels deemed non‑compliant are routinely struck by Iranian forces, while the United States periodically launches strikes on the Iranian coast to challenge the Islamic Republic’s hold on the strait.

Oil prices climbed above $100 a barrel again for the first time since May and rose further on Monday after Saudi Arabia shut a major East‑West energy pipeline following damage from Iraqi drones.

U.S. West Texas Intermediate futures gained 2.3% to $102.39 per barrel, and Brent crude, the global benchmark, rose 2.4% to $107.11 per barrel.
