This summary consolidates reporting on multiple scientific and space exploration developments from the past week, including a crewed lunar mission, a Mars rover issue, medical research, conservation efforts, and new archaeological findings.
Space Exploration
Artemis II Mission
NASA's Artemis II mission, a joint operation with the Canadian Space Agency, completed a lunar flyby and returned to Earth with a splashdown in the Pacific Ocean. The Orion capsule's heat shield was tested during re-entry at speeds of approximately 40,000 km/h (25,000 mph).
The crew flew farther from Earth than any previous human mission; they observed the far side of the moon and a total eclipse from space. NASA released over 12,000 images from the mission.
Artemis II Launch Preparations
NASA is finalizing preparations to roll out its Artemis II Space Launch System (SLS) rocket and Orion spacecraft at Launch Pad 39B in Florida, with a targeted launch in early February. The rocket is undergoing repairs due to a helium leak.
The Artemis program has been revised to include an additional in-orbital docking mission in 2027, preceding a planned crewed lunar landing. The Artemis III mission is scheduled for a launch next year, with two crewed lunar surface missions planned for 2028.
Lunar Base Plans
NASA announced plans for a permanent moon base and a nuclear-powered spacecraft for Mars missions. According to the agency's administrator, a planned lunar orbit space station will be canceled, with its components repurposed for the moon base. The lunar base plans reportedly involve deploying drones and robotic landers to establish a nuclear power station on the moon's surface by 2036.
Mars and Other Space Missions
NASA's Curiosity rover on Mars experienced an unusual event on April 29, 2025, during a sampling attempt. A rock slab, designated Atacama, approximately 1.5 feet wide and weighing nearly 30 pounds, became stuck on the drill bit after drilling. The rock remained attached to the drill sleeve as the rover retracted its arm, a first in the rover's 14 years of operation. The rock was freed and dropped away on May 1 after the team tilted, rotated, and vibrated the drill.
Funding for NASA's Mars sample return mission, intended to retrieve rocks collected by the Perseverance rover, was officially halted this week. This development suggests that the China National Space Administration (CNSA) may be the first to return Martian samples to Earth.
Other Space Discoveries
- New images from the Atacama Large Millimeter/submillimeter Array (ALMA) radio telescope depict 650 light-years of gas structures surrounding the Milky Way's central black hole.
- Astronomers may have observed a star collapsing directly into a black hole for the first time.
- The Vera C. Rubin Observatory issued 800,000 alerts in one day.
- The James Webb Space Telescope identified auroras in Uranus' atmosphere.
- The Hubble Space Telescope captured an image of a protoplanetary disk ("Dracula's Chivito") nearly 400 billion miles wide.
- A Chinese lander reportedly detected a large radiation cavity between Earth and the moon.
- NASA's Roman Space Telescope was preserved from budget cuts.
International Space Station
The ISS Crew-11 returned early on Thursday, January 15, due to an astronaut experiencing an undisclosed medical issue. This marks the first early return in the station's 25-year history. The ISS will be occupied by four astronauts until Crew-12 arrives next month.
Conservation and Environment
Kākāpō Breeding Season
The New Zealand kākāpō recovery program reported 105 egg hatchings this season, the highest number in 30 years for the endangered, flightless parrot. The kākāpō population declined significantly in the 1990s due to hunting, habitat loss, and introduced predators.
Tiger Reintroduction
Tigers are slated for reintroduction to Kazakhstan by the end of the year, over 70 years after their local extinction near Lake Balkhash. The initiative involves planting approximately 100,000 tree seedlings to restore habitat. The tigers are expected to be imported from a closely-related subspecies in Russia. The re-established ecosystem is anticipated to support prey animals such as boar and Bactrian deer.
Climate and Environmental Research
A study found that major river deltas globally, including the Nile, Amazon, and Ganges, are sinking at a faster rate than sea levels are rising, attributed primarily to groundwater pumping, urban growth, and reduced sediment flows.
A report indicated that the first two weeks of the ongoing conflict in Iran released a substantial amount of carbon dioxide, primarily due to building destruction, exceeding the combined emissions of 84 low-carbon-emitting countries. The long-term climate impact is expected to be greater due to fuel and fertilizer shortages resulting from Iran's Strait of Hormuz blockade.
Archaeological and Historical Discoveries
Shroud of Turin
A DNA analysis of the Shroud of Turin found genetic material from multiple human individuals and various other species, including plants (carrots, melons) and animals (red coral). Some researchers, according to the analysis, suggest the material could have originated in India; other experts disagree.
The Shroud of Turin is a linen cloth that some believe was used to bury Jesus of Nazareth. Previous scientific dating has placed its origin in the medieval period. Scholars cited in the report stated that scientific evidence supports arguments that the Shroud of Turin is a medieval creation.
Viking Presence in North America
An 11th-century silver Norse coin discovered in Maine in the 1950s has prompted discussion regarding potential Viking presence in the region.
Ancient Dental Practices
Archaeological findings in northern Vietnam's Red River delta indicate that the practice of teeth blackening dates back to the Iron Age, approximately 2,000 years ago.
Other Archaeological Finds
- A Roman mosaic depicting a topless woman battling a leopard in an arena was discovered.
- Archaeologists in Mexico found a 1,000-year-old altar and evidence of human sacrifices from the Toltec Empire.
Medical and Biological Research
Type 1 Diabetes
Research into functional cures for type 1 diabetes is advancing, with new therapies in development. Type 1 diabetes is an autoimmune condition where the pancreas produces little to no insulin, requiring daily management through insulin administration and blood sugar monitoring.
Human Reproduction in Space
A new study indicated that human reproduction in space faces significant challenges. Simulated microgravity adversely affected sperm navigation, fertilization, and embryo development.
Other Medical Findings
- A lung infection, organ damage, and forgetfulness in a patient were attributed to a parasite not previously identified in humans.
- COVID-19 vaccination during pregnancy may reduce the risk of preeclampsia.
- Research indicates that many retinal diseases previously considered "monogenic" may involve more complex genetic interactions than single gene mutations.
Environmental DNA Research
Advances in sequencing environmental DNA are progressing, facilitating species detection, food web mapping, and biodiversity charting without direct organism tracking.
Paleontology
Woolly Rhino DNA
Scientists have extracted and sequenced the genome of woolly rhino flesh found in the stomach of a 14,400-year-old mummified wolf pup discovered in Siberian permafrost. The analysis indicates that the woolly rhino population was genetically uniform, which may have hindered its adaptation to ancient climate change.
Other Fossil Discoveries
The most complete Homo habilis skeleton to date, dating back over 2 million years, was found.
Other Scientific Developments
- MIT announced a chip stacking breakthrough that could reduce energy consumption in AI processes.
- Research identified a "Half-Möbius" molecule with unique properties.
- Researchers filmed female sperm whales assisting in a birth, marking the first observed instance of such cooperative behavior in non-primates.
- A "thermodynamic computer" mimicking AI neural networks with lower energy consumption was developed.
- An ultrafast quantum chemistry engine was designed to accelerate the development of new medicines and materials.
