The European Space Agency’s (ESA) Solar Orbiter spacecraft is traveling through the cosmos. Its destination: the inner solar system. The 3,900-lb. (1,800-kg) spacecraft will work in tandem with NASA’s Parker Solar Probe to unravel solar mysteries that have puzzled scientists for decades.

The probe will spend the next two years cruising towards the sun and using both Venus and the Earth to slingshot itself out of the ecliptic plane — the area of space where all planets orbit. This vantage point will allow the spacecraft to eventually look down upon the sun’s polar regions and snap the very first images of this crucial area.

“We believe this area holds the keys to unraveling the mysteries of the sun’s activity cycle,” Daniel Müller, the mission’s ESA project scientist, said in a prelaunch science briefing on Feb. 7.

The Solar Orbiter and its suite of 10 specialized instruments will act as a mobile laboratory in space, tracking eruptions of solar materials from their origin on the surface of the sun, out into space, and all the way down to Earth.

“Our entire solar system is governed by the activity that comes from the sun,” Nicky Fox, director of NASA’s Heliophysics Division said during the mission’s science briefing. “There’s a continually streaming kind of soup of energetic particles that moves away from the sun and bathes all the planets. We call that the solar wind.”

Together, the solar wind and the sun’s magnetic field create a huge bubble known as the heliosphere, which shields the Earth from powerful interstellar radiation called cosmic rays.

Coronal mass ejections (CMEs) are energetic eruptions of solar material and when they make it to Earth, the solar particles can interact with our planet’s magnetic field to produce powerful electromagnetic fluctuations. Known as geomagnetic storms, they are troublesome because they’re known to disrupt technologies like communications systems and even power grids.

Additionally, they can also be dangerous to astronauts and satellites in space.  Solar Orbiter will help mitigate damages from these types of storms by helping scientists better predict when they might happen.

Solar Orbiter launched atop an Atlas V rocket on Feb. 9 at 11:03 p.m. EST (0403 GMT on Feb. 10). About an hour after liftoff, the spacecraft separated from the rocket’s upper stage as planned, extended its solar arrays and sent a signal back to Earth that it had power.

The spacecraft then spent the next several days deploying its communication antennas as well as its instrument boom.

Its first three months are what’s known as a commissioning phase, during which ground controllers will check out the onboard instruments to make sure everything is in working order. Two years from now, the spacecraft will be close enough to take its first detailed measurements of the sun, but we didn’t have to wait that long for the first bits of science data to come in.

Solar Orbiter carries ten scientific instruments, four in situ (meaning they measure the environment around the spacecraft) and six remote-sensing imagers (which will measure the sun’s properties). The majority of the in situ instruments are located on a 4.4-m-long extendable boom. They study the electromagnetic characteristics of the solar wind, as well as the stream of charged particles flowing from the Sun.

“We measure magnetic fields thousands of times smaller than those we are familiar with on Earth,” Tim Horbury, principal investigator for the magnetometer (MAG) instrument on the Solar Orbiter, said in the statement. “Even currents in electrical wires make magnetic fields far larger than what we need to measure. That’s why our sensors are on a boom, to keep them away from all the electrical activity inside the spacecraft.”

Designed to measure the strength and direction of the magnetic field, the MAG (which is composed of two sensors) was the first instrument to send back data.

“The data we received shows how the magnetic field decreases from the vicinity of the spacecraft to where the instruments are actually deployed,” Horbury said in the same statement. “This is an independent confirmation that the boom actually deployed and that the instruments will, indeed, provide accurate scientific measurements in the future.”

The boom is a pole made constructed out of titanium and carbon-fiber that houses three instruments, which are so sensitive that they need to be kept away from the main body of the spacecraft to avoid potential electromagnetic disturbances.

“Measuring before, during, and after the boom deployment helps us to identify and characterize signals that are not linked to the solar wind, such as perturbations coming from the spacecraft platform and other instruments,” Matthieu Kretzschmar, lead co-investigator of the high-frequency magnetometer of the Radio and Plasma Waves instrument (RPW) instrument, which is also located on the boom and will study properties of the solar wind.

The team will continue to calibrate the spacecraft’s suite of instruments and will begin collecting official science data as early as May.

Elon Musk explains why he cannot be fired from SpaceX

Elon Musk cannot be fired from SpaceX, and there’s a reason for that.

In a blunt post on X on Friday, Elon Musk confirmed plans to structurally shield his leadership at SpaceX, ensuring he cannot be fired while tying a potential trillion-dollar compensation package to the company’s long-term goal of establishing a self-sustaining colony on Mars.

The revelation stems from a Financial Times report detailing SpaceX’s intention to restructure its governance and compensation framework. The moves are designed to protect Musk’s control and align his incentives with the company’s founding mission rather than short-term financial pressures. Musk’s reply left no ambiguity:

“Yes, I need to make sure SpaceX stays focused on making life multiplanetary and extending consciousness to the stars, not pandering to someone’s bullshit quarterly earnings bonus!”

He added that success in this “absurdly difficult goal” would generate value “many orders of magnitude more than the economy of Earth,” though he cautioned that the journey will not be smooth. “Don’t expect entirely smooth sailing along the way,” Musk wrote.

The strategy reflects Musk’s deep concerns about how public-market expectations could derail SpaceX’s core objective. Founded in 2002, SpaceX has repeatedly stated its purpose is to reduce the cost of space travel and ultimately make humanity a multiplanetary species.

Unlike Tesla, which went public in 2010 and has faced repeated battles over Musk’s compensation and board influence, SpaceX remains privately held. Musk has long resisted taking the rocket company public precisely to avoid the quarterly earnings treadmill that forces most CEOs to prioritize short-term stock performance over ambitious, high-risk projects.

By embedding protections against his removal and linking any outsized pay package to verifiable milestones—such as a functioning Mars colony—SpaceX aims to insulate its leadership from activist investors or board members who might demand faster profits or safer bets.

Musk has referenced past experiences, including his ouster from OpenAI and shareholder lawsuits at Tesla, as cautionary tales. In those cases, he argued, external pressures risked diluting the original vision.

Critics may view the arrangement as excessive, especially given Musk’s already substantial voting power and wealth. Supporters, however, argue it is a necessary safeguard for a company pursuing goals measured in decades rather than quarters. Achieving a Mars colony would require sustained investment in Starship development, orbital refueling, life-support systems, and in-situ resource utilization—technologies that may deliver no immediate financial return.

Musk’s post underscores a broader philosophical point: true breakthrough innovation often demands tolerance for volatility and a willingness to ignore conventional business wisdom. As SpaceX prepares for increasingly ambitious Starship test flights and eventual crewed missions, the new governance structure signals that the company’s North Star remains unchanged—humanity’s expansion beyond Earth.

Whether the trillion-dollar package materializes depends on execution, but Musk’s message is clear: SpaceX exists to reach the stars, not to chase the next earnings beat. For investors or employees who share that vision, the protections are not a perk—they are a prerequisite for success.

Delta Airlines rejects Starlink, and the reason will probably shock you

In a pointed exchange on X, Elon Musk defended SpaceX’s uncompromising approach to Starlink’s in-flight internet service, explaining why Delta Air Lines walked away from a deal.

SpaceX frontman Elon Musk explained on Wednesday why commercial airline Delta got cold feet over offering Starlink for stable internet on its flights — and the reason will probably shock you.

In a pointed exchange on X, Elon Musk defended SpaceX’s uncompromising approach to Starlink’s in-flight internet service, explaining why Delta Air Lines walked away from a deal.

Delta rejected Starlink because it insisted on routing all connectivity through its branded “Delta Sync” portal rather than allowing a simple Starlink experience.

Instead, the airline partnered with Amazon’s Project Kuiper—rebranded as Amazon Leo—for high-speed Wi-Fi on up to 500 aircraft, with rollout targeted for 2028. At the time of the announcement, Kuiper had roughly 300 satellites in orbit, while Starlink operated more than 10,400.

The use of the “Delta Sync” portal would not work for SpaceX, as Musk went on to say that:

“SpaceX requires that there be no annoying ‘portal’ to use Starlink. Starlink WiFi must just work effortlessly every time, as though you were at home. Delta wanted to make it painful, difficult and expensive for their customers. Hard to see how that is a winning strategy.”

Musk doubled down in a follow-up post:

“Yes, SpaceX deliberately accepted lower revenue deals with airlines in exchange for making Starlink super easy to use and available to all passengers.”

SpaceX has structured its airline agreements to prioritize zero-friction access—no captive portals, no SkyMiles logins, no paywalls or ads blocking basic connectivity.

While this means forgoing higher-margin deals that would let carriers monetize the service more aggressively, it ensures Starlink feels like home broadband at 35,000 feet. Passengers on partner airlines such as United, Qatar Airways, and Air France have already praised the service for enabling seamless video calls, streaming, and work mid-flight without interruptions.

Delta’s choice reflects a different philosophy. By keeping Wi-Fi behind its Delta Sync ecosystem, the airline aims to drive loyalty program engagement and control the digital passenger journey. Yet, critics argue this short-term control comes at the expense of immediate competitiveness.

Airlines already installing Starlink are pulling ahead in customer satisfaction surveys, while Delta passengers face years of reliance on slower, legacy systems until Leo launches.

SpaceX’s decision to trade revenue for simplicity will pay off in the longer term, as Starlink is already positioning itself as the default high-speed option for carriers that value passenger satisfaction over incremental fees.

Musk’s focus on creating not only a great service but also a reasonable user experience highlights SpaceX’s prowess with Starlink as it continues to expand across new partners and regions.

The timing couldn’t be more symbolic. With trillion-dollar CEOs and the President sharing the cabin, Starlink wasn’t just a nice-to-have—it was mission-critical. No more spotty signals or dropped calls. Instead, real-time video conferences, secure data transfers, and global coordination at Mach speed.

Starlink’s aviation push has already transformed commercial and private flying. Dozens of major airlines have signed on or begun rollouts.

Hawaiian Airlines, United Airlines, Qatar Airways, Air France, SAS, WestJet, airBaltic, and Emirates (now equipping its Boeing 777 and A380 fleets) offer Starlink Wi-Fi to passengers. Lufthansa plans to follow in late 2026.

On private jets, the upgrade is even hotter: owners and charter companies report skyrocketing demand because Starlink turns cabins into flying boardrooms.

Starlink gets its latest airline adoptee for stable and reliable internet access

The advantages are massive. Traditional in-flight Wi-Fi relied on slow, high-latency geostationary satellites or ground-based systems that cut out over oceans and remote areas. Starlink’s low-Earth-orbit constellation delivers blazing speeds—often exceeding 200 Mbps download with latency as low as 25-60 milliseconds—gate-to-gate, from takeoff to landing.

Passengers stream 4K video, join Zoom calls, or work in the cloud without buffering. Pilots get real-time weather, NOTAM updates, and live ATC data. Even private-jet travelers get the benefits, as it means productivity that rivals the office.

On Air Force One, those benefits become strategic superpowers. The presidential aircraft demands unbreakable communications for national security, diplomacy, and crisis response. Starlink provides global coverage with no dead zones, offering redundancy against traditional systems that could fail in contested airspace or during long-haul flights.

It enables the President and staff to maintain secure links with the Pentagon, allies, or business leaders anywhere on Earth. During the Beijing trip, it likely facilitated direct coordination on trade, tech, and AI—proving the system’s reliability for the highest-stakes missions.

Critics once dismissed Starlink as a rich-person toy or military experiment. Now, it’s the backbone of commercial fleets, private aviation, and the world’s most visible symbol of American power, and it is providing stable internet to travelers.

With over 2,000 commercial aircraft committed and private-jet installations booming, Starlink is rewriting the rules of connected flight, and it seems like each week, a new airline is choosing to use it for on-flight connectivity.

For Air Force One, it’s more than faster Wi-Fi. It’s uninterrupted command-and-control in an increasingly connected world—ensuring the President never has to go dark at altitude. Elon Musk just made sure of it.
