Fiery End for the Peregrine: First US Lunar Lander in 50 Years Faces Unexpected Conclusion

The much-anticipated Peregrine spacecraft, the harbinger of the first US lunar landing mission in over 50 years, is now veering towards a fiery reentry after a critical fuel leak thwarted its lunar ambitions. Developed by Astrobotic Technology under a $108 million contract with NASA, the Peregrine lander encountered a series of challenges, including an anomaly affecting its solar-powered battery and the fuel leak that left it without sufficient propellant for the planned lunar touchdown.

The failed mission marks a setback for NASA’s Commercial Lunar Payload Services (CLPS) program, which enlists private companies to explore the lunar surface as part of the agency’s broader goal to return humans to the moon later this decade.

Astrobotic Technology, based in Pittsburgh, made the decision to dispose of the spacecraft by allowing it to disintegrate midair during reentry, ensuring a responsible and safe conclusion to the mission. The company stated that although the spacecraft could have potentially operated for several more weeks, the anomalous state of the propulsion system led to the decision to end the mission.

The Peregrine lander faced challenges en route to the moon, including an “anomaly” that affected its battery orientation and the fuel leak, hindering its soft landing on the lunar surface. The exact cause of the leak remains unknown.

While Astrobotic had disposal options, including leaving the spacecraft adrift in space or crash-landing it on the moon, the company opted for a controlled reentry to avoid the risk of the damaged spacecraft causing issues or becoming uncontrolled debris in space. The mission’s unexpected end is expected to be discussed further during a news conference scheduled for Thursday at 12 p.m. ET by Astrobotic and NASA.

Despite the critical errors and inability to complete the lunar landing, the Peregrine lander did manage to achieve some scientific objectives. Two of NASA’s payloads gathered data on radiation levels in space, providing valuable insights for future lunar missions. Additionally, a new sensor called the Navigation Doppler Lidar, developed by NASA, was successfully activated, contributing to technical knowledge and scientific data for future lunar deliveries.

While the Peregrine spacecraft’s mission faced an early conclusion, it has left an indelible mark on lunar exploration, emphasizing the challenges and complexities of space endeavors.

SpaceX’s Starship Test Ends in Explosion, Raising Concerns for Future Missions

SpaceX’s highly anticipated Starship test faced a setback as the rocket system, touted as the most powerful ever built, safely lifted off but ended prematurely with an explosion and loss of signal. The Super Heavy booster and Starship spacecraft separated successfully, but the booster was destroyed, erupting into flames over the Gulf of Mexico. Despite this, the Starship spacecraft briefly continued its journey, reaching an altitude of about 93 miles above Earth.

The test marked a significant advancement compared to the April attempt, with the spacecraft achieving near orbital velocities. However, issues arose during the “hot staging” process, a risky phase where the Starship spacecraft uses its engines to separate from the Super Heavy booster. The booster, intended for a controlled landing, instead tumbled out of control and exploded, prompting the mission’s early termination.

The Federal Aviation Administration (FAA) confirmed a mishap during the test but reported no injuries or property damage. An FAA investigation will determine the root cause, potentially affecting Starship’s development and future missions, including NASA’s Artemis III lunar mission. NASA Administrator Bill Nelson expressed optimism, stating that setbacks are opportunities to learn and improve, emphasizing the collaborative efforts between NASA and SpaceX for future space exploration.

NASA’s Psyche Probe Embarks on a Historic Mission to Metal Asteroid 16 Psyche

In a remarkable and unprecedented journey of discovery, NASA’s Psyche probe has officially launched on a mission to explore the enigmatic metal asteroid known as 16 Psyche. The asteroid, believed to be composed of up to 60% iron and nickel, is poised to reveal the secrets of our Solar System’s distant past.

The launch of the spacecraft, aptly named Psyche, took place from Cape Canaveral, Florida, and was carried into space by a Falcon-Heavy rocket. The launch occurred at precisely 10:19:43 local time, embarking on a six-year, 2.2-billion-mile journey to 16 Psyche, positioned between the orbits of Mars and Jupiter.

Scientists are brimming with anticipation as they believe this mission will provide unprecedented insights into the formation of the Solar System. While there are approximately one and a half million known asteroids in our Solar System, only nine exhibit properties similar to Psyche. Among these, Psyche stands out as the largest, with a diameter of about 175 miles (280 kilometers).

Principal investigator Prof. Lindy Elkins-Tanton from Arizona State University expressed her excitement, stating, “The big thrill is that we’re going to go see a kind of world that humans have never seen before. We don’t have any close-up pictures of it; we do not know what it looks like. To me, that’s the essence of exploration, that people always want to see what they haven’t seen yet.”

The Psyche spacecraft is set to reach the asteroid in August 2029, where it will enter orbit at various distances, the closest being approximately 47 miles (75 kilometers). During its mission, the probe will map the asteroid’s shape and conduct studies to decipher its internal structure and composition, promising fascinating and potentially groundbreaking discoveries.

One intriguing aspect that scientists hope to observe is the impact of high-speed micrometeoroids on the asteroid’s surface, potentially resulting in the development of a unique, spiky appearance and perhaps a covering of “metal sand.”

While telescopes have identified iron and nickel as the predominant components of 16 Psyche, other elements, possibly yellowish-green, sulfur-rich rocks, have been detected. The presence of metal cliffs, believed to have formed as Psyche cooled and cracked over the past 4.6 billion years, is also a possibility.

Deputy principal investigator, Ben Weiss, explained two leading theories regarding Psyche’s origin. One suggests that Psyche is the exposed core of a planetary body, stripped of its outer rocky layers by asteroid impacts during the early Solar System’s tumultuous era. The other posits that Psyche may be a pristine, unmelted body formed from the Solar System’s earliest materials, preserved in its initial state.

If Psyche does indeed prove to be the exposed core of a failed planet, it might exhibit a “fossil” magnetic field, providing insights into the dynamics of the early Solar System. Furthermore, the composition of metal meteorites on Earth, believed to originate from objects similar to Psyche, has raised the possibility of asteroid mining, with Psyche’s resources estimated to be worth trillions of dollars.

NASA plans to trial two innovative technologies during the mission. The first involves electric propulsion, using solar power to excite and accelerate xenon gas for continuous thrust. The second employs laser beams to enhance data transmission rates.

The mission team has committed to making all imagery and data collected by Psyche available to the public within half an hour of it reaching Earth, ensuring that this historic mission remains accessible to all.

Researchers Successfully Extract RNA from Extinct Species, Marking a Historic Breakthrough

Geneticists have achieved a groundbreaking scientific feat by isolating and decoding RNA molecules from an extinct Tasmanian tiger specimen, which was over 130 years old and stored at the Swedish Museum of Natural History. This achievement provides valuable insights into how the genes of this long-extinct species functioned and was detailed in a study published in the journal Genome Research.

Lead study author Emilio Mármol Sánchez, a computational biologist at the Centre for Palaeogenetics and SciLifeLab in Sweden, highlighted the significance of RNA in understanding the animal’s biology, explaining that it offers a unique window into the cells and tissues of the thylacine right before its extinction.

The Tasmanian tiger, roughly the size of a coyote, was a marsupial predator that disappeared nearly 2,000 years ago in most regions except Tasmania, where it was hunted to extinction by European settlers. The last thylacine, named Benjamin, lived in captivity and died from exposure in 1936.

While the primary goal of this research wasn’t de-extinction, it could contribute to ongoing efforts to bring back the Tasmanian tiger in some form. Andrew Pask, who leads a project aimed at resurrecting the thylacine, hailed the research as “groundbreaking” and noted that it expands our understanding of extinct species’ biology.

RNA, often considered a temporary copy of DNA, was previously thought to break down quickly and was not expected to endure. However, this study demonstrates that RNA can be retrieved from long-extinct animals, challenging previous assumptions. The research team hopes to extend their work to recover RNA from even older extinct species, such as the woolly mammoth.

By sequencing RNA from the Tasmanian tiger specimen’s skin and skeletal muscle tissues, scientists identified thylacine-specific genes, contributing to the animal’s transcriptome. This RNA-based approach complements DNA analysis, offering a more comprehensive understanding of an animal’s biology. Mármol Sánchez likened DNA to a recipe book for life, while RNA allows each “restaurant” (or cell) to create different dishes based on that reference book.

In essence, this groundbreaking research not only provides new insights into extinct species’ genetics but also opens the door to further discoveries and a deeper understanding of the biology of long-lost creatures.

The Potential of AI as a Game-Changing Tool in Addressing Male Infertility

A team of researchers led by Dr. Steven Vasilescu from the University of Technology Sydney has developed an AI software called SpermSearch to assist in solving male infertility. The AI can rapidly identify viable sperm in samples taken from severely infertile men, doing so 1,000 times faster than a highly trained human observer. This technology is particularly beneficial for men with a condition called non-obstructive azoospermia (NOA), where they have no sperm in their ejaculate. Traditionally, embryologists manually search for healthy sperm in surgically removed testes tissue, a time-consuming and labor-intensive process.

SpermSearch significantly speeds up this process by analyzing photographs of tissue samples and instantly identifying viable sperm. The AI was trained using thousands of images of complex tissue samples to achieve this remarkable speed. While SpermSearch is not intended to replace embryologists, it acts as an assistive tool, saving critical time in identifying viable sperm for fertilization.

The ability to quickly find viable sperm is crucial in fertility treatments, as there is a limited time window for fertilization once eggs are collected. Male infertility has become a growing concern, with factors such as pollution, smoking, poor diets, lack of exercise, and stress contributing to a decline in sperm counts.

Other researchers are also exploring AI applications in addressing male infertility. For instance, another technique tracks the speed and movement of sperm tails to assess their health, while a different approach identifies DNA damage in individual sperm cells.

While these AI developments are promising, they are still in the proof-of-concept stage and will require further clinical trials before becoming commercially available. Nonetheless, such advancements offer hope for men facing infertility issues, potentially increasing their chances of fathering biological children. The University of Technology Sydney team is currently preparing for clinical trials, with the ultimate goal of achieving a live pregnancy using their AI technology.
