A US government watchdog on Friday sided with NASA over its decision to pick a single lunar lander provider, rejecting a protest filed by Blue Origin and defense contractor Dynetics Inc.

The companies had challenged the $2.9 billion award to Elon Musk’s SpaceX for the lander, arguing NASA was required to make multiple awards. The Government Accountability Office (GAO) said it “denied the protest arguments that NASA acted improperly in making a single award to SpaceX.”

Blue Origin, the rocket company founded by billionaire Jeff Bezos, said on Friday it remained convinced that there were “fundamental issues” with NASA’s decision, and that GAO was not able to address them “due to their limited jurisdiction.”

Blue Origin said it will continue to advocate for two immediate providers as it believes that to be the right solution.

“GAO’s decision will allow NASA and SpaceX to establish a timeline for the first crewed landing on the Moon in more than 50 years,” NASA said in a statement on Friday, adding that sending American astronauts to the moon is a priority for the Biden Administration.

Dynetics, a unit of Leidos Holdings, said it was disappointed with the decision, but plans to compete for other opportunities announced by NASA in the future.

SpaceX did not comment, but Musk sent a tweet saying just “GAO” with a flexed muscle emoji.

NASA had sought proposals for a spacecraft that would carry astronauts to the lunar surface under its Artemis program to return humans to the moon for the first time since 1972.

In April, NASA awarded SpaceX a contract to build such a spacecraft as early as 2024.

Blue Origin had contended NASA gave SpaceX an unfair advantage by letting it revise its pricing.

On Monday, Bezos offered to cover up to $2 billion in NASA costs if the U.S. space agency awarded Blue Origin a lunar landing contract.

In a letter to NASA Administrator Bill Nelson, Bezos said Blue Origin would waive payments up to $2 billion, and pay for an orbital mission to vet its technology. In exchange, Blue Origin would accept a firm, fixed-priced contract, and cover any system development cost overruns.

“Without competition, NASA’s short-term and long-term lunar ambitions will be delayed, will ultimately cost more, and won’t serve the national interest,” Bezos said.

Bezos’ offer came six days after he flew alongside three crewmates to the edge of space aboard Blue Origin’s rocket-and-capsule New Shepard.

Solar System’s Journey Through Orion Complex May Have Altered Earth’s Climate

The movement of the solar system through the Orion star-forming complex around 14 million years ago may have influenced Earth’s climate, according to scientists. This dense region of space, part of the Radcliffe Wave galactic structure, could have compressed the heliosphere—the protective shield surrounding the solar system—while increasing interstellar dust reaching Earth. Researchers suggest that this influx of cosmic dust might have left traces in geological records, potentially linking galactic activity to past climate changes.

Solar System’s Passage Through the Radcliffe Wave

According to the study published in Astronomy & Astrophysics, an international research team led by the University of Vienna used data from the European Space Agency’s Gaia mission and spectroscopic observations to determine that the solar system moved through the Radcliffe Wave in the Orion constellation between 18.2 and 11.5 million years ago. The most probable period was estimated between 14.8 and 12.4 million years ago. João Alves, Professor of Astrophysics at the University of Vienna and co-author of the study, stated to Phys.org, that this research builds on prior findings regarding the Radcliffe Wave. This structure, made up of interconnected star-forming regions, includes the Orion complex, which the sun is believed to have passed through.

Potential Impact on Earth’s Climate

The study suggests that the increased presence of interstellar dust may have influenced Earth’s atmosphere. Efrem Maconi, lead author and doctoral student at the University of Vienna, said that this dust might have contained traces of radioactive elements from supernovae, which could be detected in geological records using advanced technology in the future.

The solar system’s passage aligns with the Middle Miocene Climate Transition, a period marked by a shift from a warmer, variable climate to a cooler one, leading to the development of Antarctic ice sheets. Scientists highlight that while interstellar dust could have played a role, the dominant factor in this climate change was a long-term decrease in atmospheric carbon dioxide levels.

Not Comparable to Human-Induced Climate Change

Maconi noted that while interstellar dust could have contributed to past climate shifts, the amount required for significant change would need to be much greater than current data suggests. The Middle Miocene Climate Transition unfolded over hundreds of thousands of years, unlike modern climate change, which is occurring rapidly due to human activities

Ancient DNA Sheds Light on the Diverse Genetic Origins of the European Huns

The origins of the Huns, a nomadic group that played a crucial role in the decline of the Roman Empire, have long remained uncertain. Recent DNA analysis of ancient skeletal remains has provided fresh insights into their ancestry, revealing a diverse genetic makeup rather than a singular point of origin. According to reports, researchers examined remains from individuals buried between the fourth and sixth centuries and found genetic links spanning Central Asia and Eastern Europe. These findings indicate that the Huns were not a homogenous group but a population shaped by centuries of migration and cultural interactions.

Genetic Analysis Reveals Diverse Ancestry

According to the study published in PNAS, a team led by Guido Gnecchi-Ruscone, an archaeogeneticist at the Max Planck Institute for Evolutionary Anthropology, analysed the genomes of 370 individuals. The research aimed to trace connections between European Huns and earlier nomadic groups, including the Xiongnu, whose empire thrived in Mongolia between 200 B.C. and A.D. 100. While certain Hun individuals exhibited direct genetic links to the Xiongnu elite, most carried varying degrees of Northeast Asian ancestry, underscoring a complex history of intermingling.

Connections Across the Eurasian Steppe

Using a technique called identity by descent (IBD) segment sharing, the researchers identified genetic ties across multiple regions over several centuries. Their findings suggested that trans-Eurasian relationships were maintained across generations. While high-status Xiongnu burials in Mongolia showed direct descendants among the European Huns, the study concluded that no large-scale migration of Xiongnu populations into Europe took place.

Insights from an Elite Hun Burial

A burial site in Pusztataskony, Hungary, yielded the remains of a Hun woman with an elongated skull, buried alongside gold earrings. Gnecchi-Ruscone told Live Science that this individual carried genetic markers linking her to the Xiongnu elite, suggesting that skull modification, a notable cultural practice, may have been passed down through generations. The study reinforces the view that the European Huns were a culturally and genetically diverse group shaped by centuries of movement and integration rather than a single migratory event.

NASA’s IM-2 Mission Brings Ice Mining, Mobile Robots, and More on Moon

NASA is preparing to send advanced technologies to the Moon through Intuitive Machines’ second lunar delivery under the Commercial Lunar Payload Services (CLPS) initiative. The mission, part of the Artemis programme, aims to establish a sustainable human presence on the Moon. A range of scientific instruments and communication systems will be tested on the lunar surface. The launch window for Intuitive Machines’ second CLPS mission, IM-2, is scheduled to open on 26 February from Launch Complex 39A at NASA’s Kennedy Space Center. The Nova-C class lander will carry key technology payloads, including a drill, mass spectrometer, a cellular network, and a drone for terrain exploration.

Lunar South Pole Exploration

As reported, the landing site for IM-2 has been selected based on data from NASA’s Lunar Reconnaissance Orbiter. Located in the South Pole region, the site offers a relatively flat terrain, meeting the criteria for a safe landing. The area is of particular interest due to its potential for in-situ resource utilisation, which could support future lunar missions.

Demonstration of New Technologies

According to NASA’s Space Technology Mission Directorate, the Polar Resources Ice Mining Experiment-1 (PRIME-1) will be tested as part of the mission. PRIME-1 includes a drill and a mass spectrometer designed to search for water ice and other resources beneath the lunar surface. Data gathered from this experiment will assist in future space exploration efforts by providing insight into potential resource extraction for fuel and oxygen production.

Mobile Robotics on the Moon

Two technology demonstrations will be deployed near the lander under NASA’s Tipping Point initiative. Intuitive Machines has developed a small drone, named Grace, which will conduct high-resolution surveys of the lunar terrain. The drone is designed to navigate steep inclines, craters, and other challenging obstacles, helping scientists study permanently shadowed regions that cannot be accessed by traditional rovers.

Lunar Surface Communication System

A communication system developed by Nokia Bell Labs will be tested to establish a lunar cellular network. The system will enable communication between the lander, a Lunar Outpost rover, and the Grace drone. It will be the first demonstration of cellular-based connectivity on the Moon, with potential applications for future crewed missions and robotic exploration.

Collaboration for Lunar Exploration

NASA is working alongside several U.S. companies to deliver scientific and technological advancements to the lunar surface. The Space Technology Mission Directorate has integrated multiple research and development efforts to support future Moon missions. The combination of CLPS and Tipping Point initiatives aims to advance exploration capabilities, benefiting NASA and the broader space industry.
