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.

69-Year-Old Man with Paralysis Flies Virtual Drone Using Brain Implant

A paralysed individual, aged 69, has successfully piloted a virtual drone using a brain-computer interface (BCI) that interprets neural signals. This innovative achievement has enabled the participant to navigate a video-game obstacle course by imagining specific finger movements. The breakthrough device, which bridges brain activity and real-time control, demonstrates potential applications for assisting those with mobility challenges to engage in intricate tasks. These developments mark significant progress in the application of BCIs for enhancing motor functions.

Breakthrough Detailed in Nature Medicine

According to a study published in Nature Medicine, the man, who had been paralysed in all four limbs following a spinal cord injury, controlled the virtual drone using neural signals linked to imagined movements of specific finger groups. The research relied on electrodes implanted in the participant’s left motor cortex, which had been placed during a prior operation in 2016. Algorithms were trained to decode the brain’s signals when he visualised moving his right thumb, different finger pairs, or combinations of them.

The researchers reported that the participant initially practised synchronising imagined movements with a virtual hand displayed on a screen, achieving a high degree of accuracy by hitting up to 76 targets per minute. Subsequently, the signals were connected to the drone’s navigation system, allowing him to steer it through a virtual basketball court, manoeuvring rings with precision.

Expert Insights on Potential Applications

Matthew Willsey, a neurosurgeon at the University of Michigan and a co-author of the study, told Nature Medicine that the participant likened the experience to playing a musical instrument, requiring delicate adjustments to maintain control. Willsey noted that the research seeks to enable control of multiple movements simultaneously, potentially assisting activities such as typing or playing musical instruments.

John Downey, a BCI researcher from the University of Chicago, described the work as an important initial step in understanding hand control mechanisms. He highlighted the potential of this technology as a versatile tool for individuals with limited mobility. Researchers aim to enhance the system to decode signals for all ten fingers.

Hubble Telescope Observes Two Young Stars in Orion Nebula

Two young stars have been captured in a new image taken by the Hubble Space Telescope, located in the Orion Nebula, a well-known region for star formation. The stars, named HOPS 150 and HOPS 153, are situated approximately 1,300 light-years from Earth. The Orion Nebula is considered the closest massive star-forming region to Earth and contains hundreds of newly forming stars. The image provides insight into the ongoing process of star birth, showing the stars in their early stages as they gather material from their surrounding environment.

Protostars Observed in Orion Nebula

As reported by space.com, according to the European Space Agency’s (ESA) statement, the stars were identified through the Herschel Orion Protostar Survey conducted using the Herschel Space Observatory. HOPS 150, which consists of two stars, a forming a binary system, is seen glowing in bright golden red in the image’s upper-right corner. The binary stars are surrounded by a large cloud of gas and dust, which continues to provide material for their growth. The protostars are said to be midway in their developmental process, based on the light they emit in different wavelengths.

Stellar Jet Emission from HOPS 153

The statement also noted that HOPS 153, located on the left side of the image, exhibits a narrow jet of colorful gas extending outward. This jet is a byproduct of the star’s evolution, as it ejects material while feeding from its surrounding disk. The colorful jet, composed of high-speed matter, interacts with the surrounding gas and dust in the nebula, influencing the formation of new stars in the region.

Future Evolution of the Young Stars

ESA officials have stated that HOPS 153 is still deeply embedded in its birth cloud of cold, dense gas. While the protostar itself is not visible, the jet it emits can be clearly observed. As the star continues to develop, further material ejection is expected, which may impact the surrounding nebula and the formation of neighboring stars.

New Lithium-Sulfur Battery Retains 80 Percent Capacity After 25,000 Cycles

Engineers and materials scientists have achieved a major advancement in battery technology, developing a lithium-sulfur battery that retains 80 percent of its charge capacity after 25,000 charging cycles. The new design, which uses a specially formulated electrode, represents a significant improvement over conventional lithium-ion batteries. The breakthrough could pave the way for smaller, lighter, and longer-lasting energy storage solutions, addressing critical demands in electronics and electric vehicles.

Key Innovations in the Study

According to a study published in Nature, sulfur was utilised as a core component for the battery’s solid electrode. Despite being abundant and cost-effective, sulfur has historically posed challenges due to issues such as ion loss and expansion during reactions with lithium. These problems were tackled by incorporating a glass-like mixture composed of sulfur, boron, lithium, phosphorus, and iodine. The iodine element was found to enhance electron movement during redox reactions, allowing for faster charging and improved performance.

As reported by Techxplore, the research demonstrated that the porous atomic structure of the electrode facilitated ion diffusion, eliminating the need for intermediary movements. This structural stability, combined with the chemical properties of the glass-phase electrolyte, contributed to the battery’s durability across an unprecedented number of cycles.

Performance and Potential Applications

The experimental lithium-sulfur battery maintained its capacity even under high temperatures, a notable advantage in demanding environments. Standard lithium-ion batteries typically degrade after approximately 1,000 cycles, making this new battery’s longevity a striking development. Despite its promise, the study’s authors acknowledged the need for further research to improve energy density and explore alternative materials that could reduce the battery’s overall weight.

Efforts are being directed at refining this technology to support the growing demand for energy storage in applications ranging from consumer electronics to renewable energy systems.
