SpaceX achieved new feats during the sixth major test launch of its Starship system but nixed an eagerly anticipated midair “catch” of the rocket’s booster as President-elect Donald Trump looked on in South Texas.

SpaceX’s launch system, comprised of the booster and Starship upper spacecraft, cleared the tower shortly after 4 p.m. local time on Tuesday. But minutes into the flight, SpaceX scrapped plans to attempt to catch the booster with giant mechanical arms — referred to as “chopsticks” — which the company completed during its previous flight. The booster, dubbed Super Heavy, was still able to perform a controlled landing in the ocean.

“It was pretty epic on attempt one, but the safety of the teams and the public and the pad itself are paramount,” SpaceX engineer Kate Tice said on a live broadcast. “So we are accepting compromises.”

After Super Heavy landed in the Gulf of Mexico, Starship continued its voyage through space. At one point, it successfully reignited one of its Raptor engines — the first time SpaceX was able to do so during these flight tests. Starship will need to reignite its engines in order to control its descent to Earth and maneuver through space.

Starship then circled most of the globe before plunging through the atmosphere about 45 minutes into the mission, its body engulfed in the reddish orange glow of plasma as its upgraded heat shield endured intense temperatures while hurtling back to Earth. 

Starship appeared to survive the reentry, moving its exterior flaps to help guide its descent, though some showed signs of burn and slight damage. Then, as Starship fell through clouds, it flipped itself and reignited its engines to turn upright and softly splash into the Indian Ocean shortly after 6 p.m. New York time. It then appeared to catch on fire.

“Turns out the vehicle had more capability than our calculations predicted, and that is why we test like we fly,” Tice said.

The largest and most powerful rocket ever developed, Starship is under contract to function as a lunar lander that NASA will use to put people back on the moon for the first time in half a century. It’s the centerpiece of Musk’s ambition to start a settlement on Mars. 

The vehicle is also meant to revolutionise SpaceX’s business plan. Designed to be fully reusable, Starship will be much cheaper to fly than any other rocket, according to SpaceX, and will eventually replace the company’s industry-leading Falcon 9 and Falcon Heavy rockets. 

But to meet that promise of delivering a fully reusable rocket, SpaceX must refine its technique for recovering all of the pieces of Starship after launch.

Around the time SpaceX aborted the booster catch, Trump and Musk left to visit the Starfactory courtyard for a visual tour of the factory bays and rockets. 

Trump had arrived at a launch viewing location with Musk about an hour before liftoff. Trump, wearing a blue suit and red MAGA hat, stood flanked by allies, including Texas Republican Senator Ted Cruz and Donald Trump Jr., as the group peppered Musk with questions on how the launch works.

It was Trump’s first visit to a Starship launch. It follows several appearances with Musk, who has spent a significant amount of time at Trump’s Mar-a-Lago estate, joining in on transition meetings and phone calls with foreign leaders. The billionaire, who campaigned on behalf of Trump in crucial swing state Pennsylvania, will lead a newly created Department of Government Efficiency, an entity that will recommend federal spending cuts, alongside former Republican presidential candidate Vivek Ramaswamy.

Musk, who has been a near-constant fixture of Trump’s inner circle since the Nov. 5 election, has maintained that overregulation, especially surrounding Starship, factored into his decision to support the Republican. 

SpaceX President Gwynne Shotwell said on Friday that as many as 400 Starship flights were possible over the next four years. That frequency can only happen if SpaceX perfects its landing strategy, so the company can quickly turn around the rockets for their next flights. Shotwell described the process as similar to the way airlines drive down the cost of owning and operating commercial jetliners.

During the October test, the booster came very close to crashing near the tower, Musk said in a video on his X platform. SpaceX will need to address that issue as well as a laundry list of other things, such as refueling the vehicle in space, before Starship lives up to the full scope of Musk’s plans.

Study Reveals the Shape of a Photon for the First Time Ever

A study conducted at the University of Birmingham has identified the precise shape of a single photon, reshaping how interactions between light and matter at the quantum level are understood. The study detailed in Physical Review Letters tells us how photons, or particles of light, are emitted and influenced by their surroundings, offering possibilities for significant technological advancements.

This achievement stems from addressing a longstanding challenge in quantum physics: the near-infinite ways photons can propagate in their environment. Researchers grouped these scenarios into manageable sets, enabling a model to describe not just how photons interact with their emitters but also how energy radiates into the far field. The findings also included the first-ever visualisation of a photon, achieved through complex calculations.

Complex Problems Made Solvable

Dr Benjamin Yuen, a physicist at the University of Birmingham and lead author of the study, explained that the team converted an otherwise insurmountable problem into a computationally solvable framework. As a result, they could depict the shape of a photon—a significant milestone in quantum physics.

Photon Emission Shaped by Environment

The study, published in the Physical Review Letters, also reveals the critical role of environmental factors, including geometry and optical properties, in defining a photon’s characteristics. According to Professor Angela Demetriadou, co-author of the research, these influences extend to the photon’s colour, shape, and likelihood of being emitted. The data, previously dismissed as background noise, now serves as a valuable source of information.

Advancing Light-Matter Applications

This discovery is expected to advance the design of nanophotonic technologies. Dr. Yuen highlighted its potential to develop improved sensors, solar cells, and systems for quantum computing. A more detailed understanding of light-matter interactions could also lead to breakthroughs in secure communication and molecular-level chemical processes.

By visualising a photon for the first time, the research establishes a foundation for future exploration, marking a significant step forward in understanding the quantum world.

Chandrayaan-2 Adjusts Orbit to Avoid Collision With This Spacecraft

Chandrayaan-2 Adjusts Orbit to Avoid Collision With This Spacecraft

India’s Chandrayaan-2 lunar orbiter performed a manoeuvre in September to prevent a close encounter with the Korea Pathfinder Lunar Orbiter (KPLO), officially known as Danuri, according to the Indian Space Research Organisation (ISRO). The adjustment carried out on September 19, 2024, was necessary to avoid a potential collision between the two orbiters, which was projected for two weeks later if no changes were made to Chandrayaan-2’s trajectory.

Following this, on October 1, 2024, another orbital modification was implemented to maintain separation from other lunar orbiters, including NASA‘s Lunar Reconnaissance Orbiter (LRO), as per an ISRO report.

Frequent Collision Risks Among Lunar Orbiters

Around the lunar poles, orbiters such as Chandrayaan-2, Danuri, and LRO share a similar near-polar path, increasing the likelihood of close approaches. Over the past 18 months, the Korea Aerospace Research Institute (KARI), which operates Danuri, reported having received over 40 collision alerts for interactions among Danuri, Chandrayaan-2, and LRO. These alerts, referred to as “red alarms,” underscore the growing risk of accidental collisions as multiple international agencies operate missions in close proximity around the Moon.

Previously, in 2021, Chandrayaan-2 reportedly avoided a similar situation by shifting its path, preventing a close pass by LRO that would have brought the two within just three kilometres. Danuri itself has performed at least three orbital adjustments since it entered lunar orbit in December 2022, including avoiding both LRO and Japan’s Smart Lander for Investigating Moon (SLIM).

Lack of Unified Collision Protocols in Lunar Operations

At present, no globally coordinated protocol exists for managing collision risks around the Moon. Space agencies like ISRO, KARI, and NASA rely on direct communication, sharing spacecraft position data through email and teleconferences. However, according to Soyoung Chung, a senior researcher with KARI’s strategy and planning team, difficulties such as network security barriers and a lack of personnel contact information have, at times, complicated communication.

NASA’s Jet Propulsion Laboratory provides the Multimission Automated Deep-Space Conjunction Assessment Process (MADCAP) software, which estimates and warns of collision risks. Still, experts like Chung have suggested the need for a formal international framework for managing close approaches around the Moon.

Is the Moon Moving Away From Earth? NASA Explains Why

The Moon is gradually moving farther from Earth, a phenomenon explained by NASA scientists as a result of complex gravitational interactions. Currently, the Moon drifts away at a rate of approximately 4 centimetres per year, a process influenced by tidal forces between the Earth and its satellite. This steady separation, though imperceptible on a human timescale, has profound implications for the Earth-Moon system and its long-term evolution, as per the space agency.

The Role of Tidal Forces in the Moon’s Drift

Earth’s gravitational pull creates bulges in the Moon’s shape, while the Moon’s gravity exerts similar forces on Earth, most notably on its oceans. However, the tidal bulges on Earth lag slightly behind the Moon’s position due to the time it takes for water to respond to gravitational changes, says NASA. This lag generates friction, slowing Earth’s rotation and transferring energy to the Moon, pushing it into a higher orbit.

NASA explains that this interaction causes the Moon to drift and lengthens Earth’s day by about 2 milliseconds per century. Over billions of years, this dynamic exchange of energy has significantly shaped the relationship between the two celestial bodies.

Implications for the Distant Future

If the process continues for another 50 billion years, the Moon’s orbit will become so vast that Earth itself could become tidally locked to the Moon. This would mean that only one hemisphere of Earth would ever see the Moon in the sky. A similar phenomenon is already observed in the Pluto-Charon system, where the two bodies are mutually tidally locked.

While such changes occur on timescales far beyond human experience, they highlight the ongoing evolution of the Earth-Moon system, which began when the Moon formed around 4.5 billion years ago. NASA’s research continues to unravel the complexities of these tidal interactions, offering insights into planetary systems within and beyond our solar system.
