SPACE FORCE UNVEILS BOLD NEW PLAN FOR WARFARE
The U.S. Space Force has released its most detailed plan yet for space warfare, signaling a major shift in military strategy beyond Earth. The document, titled *“Space Warfighting: A Framework for Planners,”* presents space as an active battleground essential to U.S. military operations, moving beyond a defensive stance to include offensive strategies. It outlines methods such as orbital strikes on enemy satellites, cyberattacks to disrupt communications, and terrestrial strikes on ground-based space infrastructure. While the manual doesn’t mention specific weapons, it aims to establish a shared planning and training framework for Space Force personnel, or “guardians.” Lt. Gen. Shawn Bratton emphasized that this new approach reflects the Pentagon’s broader push for a “warfighting ethos” under the current administration. Though caution is urged to avoid space debris, the strategy acknowledges the growing threats from rivals like China and Russia. The Space Force is now asserting its role as a full-spectrum combat force. (Space News)
POSSIBLE SIGNS OF LIFE DETECTED ON EXOPLANET THEN DISPUTED
Astronomers have reported possible signs of biological activity on exoplanet K2-18 b, detecting dimethyl sulfide (DMS)—a compound produced by Earth-based microbes—using the James Webb Space Telescope. The team, led by the University of Cambridge, says this is their strongest evidence yet, though confirmation is far from certain. Their findings triggered skepticism from other scientists, who question the validity of the signal and whether it could be produced abiotically. Some argue the data is too noisy, the planet might lack water or a habitable surface, and DMS can arise through non-biological means. Past studies found no such molecules, and researchers caution against jumping to conclusions. Despite this, the case underscores the growing potential of exoplanet science and the need for further observation and validation. The discovery, while not definitive, fuels excitement and debate in the search for extraterrestrial life, especially on mini-Neptunes like K2-18 b, which are common in the universe. (Nature)
MEASLES CASES SURGE TO 800 AMID NATIONAL OUTBREAK
Measles cases in the United States have surged to 800, with 88 new cases reported by the CDC in its latest update. The outbreak is on pace to surpass 2019’s total of 1,274, the highest since measles was declared eliminated in 2000. Ten outbreaks have been identified so far, and 94% of this year’s cases are linked to them. Most patients (96%) are unvaccinated or have unknown vaccination status. Texas is the hardest hit, with 597 cases—371 from Gaines County. Outbreaks in New Mexico, Kansas, and Oklahoma have been traced to the West Texas epicenter. Michigan has reported its first outbreak since 2019, tied to a Canadian outbreak, and Montana confirmed its first cases since 1990, involving unvaccinated travelers. Half of U.S. states have reported cases, some linked to international travel. So far, 85 people have been hospitalized and three have died. Authorities are monitoring potential exposure sites and residency links. (CIDRAP)
NSF ENDS DIVERSITY AND MISINFORMATION GRANTS NATIONWIDE
The National Science Foundation (NSF) has announced it will terminate all grants aimed at increasing diversity in STEM and combating misinformation, stating these efforts no longer align with its priorities. The decision stems from a January 21 executive order by President Trump requiring the elimination of any federal programs perceived as favoring individuals based on “protected characteristics” like race, gender, or disability. As a result, NSF has canceled possibly up to 200 grants from its $1.1 billion education directorate, despite longstanding congressional mandates to promote inclusion in STEM fields. The agency now asserts it will only fund projects that benefit “all Americans everywhere” without focusing on specific groups. Additionally, research targeting misinformation or disinformation will no longer be supported, with officials citing concerns over infringing on free speech. The move follows increased political scrutiny and internal re-evaluation of approved grant proposals, effectively freezing new awards pending further review. (Science)
CATL UNVEILS FASTER CHEAPER EV BATTERIES WITH BREAKTHROUGHS
CATL, the world’s leading electric vehicle battery maker, announced major advances that could make EVs more competitive with gasoline cars. The company revealed new battery technologies that are lighter, cheaper, faster to charge, and more cold-resistant—though most won’t reach mass production for two to three years. Among the breakthroughs is the introduction of auxiliary batteries that exclude graphite, enabling higher energy density and potentially longer driving range, while also providing backup for self-driving systems. However, these batteries recharge more slowly and wear out faster, limiting them to occasional use. CATL also introduced a new system that can charge a vehicle enough for 320 miles of range in just five minutes. In addition, the company will begin producing sodium-ion batteries, which retain over 90% charge even in -40°C weather, for use in trucks and gasoline cars in China’s cold northern regions. These developments highlight CATL’s growing influence in the global EV supply chain. (New York Times)
CHINA LAUNCHES SIX EXPERIMENTAL SATELLITES IN ORBITAL MISSION
China launched six experimental Shiyan-27 satellites into orbit on April 18 using its Long March 6A rocket from Taiyuan Satellite Launch Center. The satellites are intended for space environment detection and technology testing, though specific details remain undisclosed. Western analysts believe the Shiyan series plays a role in piloting advanced space technologies, similar to the U.S. military’s classified satellite programs. The satellites were deployed into near-polar orbits, and the upper stage was placed in a slightly lower orbit. The launch marked the 11th successful flight of the Long March 6A, China’s only rocket that combines a liquid core stage with solid boosters. This mission also introduced a new “multi-satellite wall-mounted deployment” configuration, increasing integration complexity. It was China’s 20th orbital launch of 2025. The country is ramping up space activity, with the Shenzhou-20 crewed mission and Tianwen-2 asteroid mission scheduled soon, alongside recent classified launches like TJS-17, which reportedly released a secondary object in geostationary orbit.

NASA LUCY SPACECRAFT TO FLY PAST SECOND ASTEROID
NASA’s Lucy spacecraft is set to fly past its second asteroid, Donaldjohanson, this weekend as part of its mission to explore 11 space rocks, including the Trojan asteroids near Jupiter. Launched in 2021, Lucy aims to shed light on the early solar system by studying these ancient remnants of planetary formation. The flyby will occur 139 million miles from Earth, with Lucy passing within 596 miles of Donaldjohanson—an oddly shaped asteroid about 2.5 miles long. Scientists expect to better determine its size and structure, possibly resembling a bowling pin or even a snowman-like form. Named after the paleontologist who discovered the famous hominin fossil “Lucy,” the asteroid offers a rehearsal for Lucy’s key encounters with Jupiter’s Trojan asteroids starting in 2027. Lucy’s previous encounter in 2023 revealed a mini-moon orbiting the asteroid Dinkinesh. Data from the current flyby will take about 12 minutes to reach Earth, with full results expected within a day.

ASTEROID SAMPLES CONTAIN DNA BUILDING BLOCKS AND AMINO ACIDS
NASA’s OSIRIS-REx mission has returned samples from asteroid Bennu that contain a remarkable array of life-related compounds, including phosphates, ammonia, amino acids, and all five nucleobases found in DNA and RNA. These findings suggest Bennu’s parent body once had underground briny lakes and may have delivered essential ingredients for life to early Earth. Researchers were stunned by the diversity of organic molecules preserved, including a phosphorus compound not seen before in meteorites. While scientists don’t believe life evolved on Bennu itself, the discovery supports the idea that asteroids seeded Earth—and possibly other planets—with life’s building blocks. The Natural History Museum in London will showcase these findings in an exhibition opening May 16, alongside materials from the Moon, Mars, and meteorites. The exhibit invites visitors to consider profound ethical questions about how humanity might respond if life is discovered on other worlds, such as Mars, Europa, or Titan—worlds currently being explored by upcoming missions.

LICHENS SURVIVE SIMULATED MARS CONDITIONS IN NEW STUDY
Researchers have found that certain lichen species may be able to survive the extreme conditions on Mars. In a recent study, Diploschistes muscorum and Cetrarea aculeata were exposed to simulated Martian environments—including low pressure, low humidity, cold temperatures, and ionizing X-ray radiation—while kept metabolically active through hydration. D. muscorum proved more resilient, showing less oxidative stress and maintaining chlorophyll levels better than C. aculeata. Lichens’ natural adaptations, such as low metabolism, desiccation tolerance, and radiation-shielding pigments, make them strong candidates for life beyond Earth. The study is the first to demonstrate active fungal metabolism under Mars-like radiation, suggesting lichens might endure short-term Martian exposure. Their ability to maintain photosynthesis and recover after freezing highlights their hardiness. While the findings don’t suggest lichens could thrive on Mars, they do lay the groundwork for future long-term experiments and offer insights into the types of life that might survive on other worlds—or accompany humans there.

CURIOSITY FINDS CARBONATE MINERALS SIGNALING MARS HABITABILITY
While exploring Mount Sharp in Mars’ Gale Crater, NASA’s Curiosity rover discovered rich deposits of carbonate minerals, offering new clues about the Red Planet’s past habitability. Carbonates form when carbon dioxide reacts with water and rock, making them key indicators of ancient environmental conditions. Curiosity’s findings, especially of siderite—an iron-rich carbonate—and iron oxyhydroxides, suggest that Mars once had a thicker CO₂-rich atmosphere capable of supporting liquid water. As the atmosphere thinned, carbon began locking into rock, potentially destabilizing the climate and ending Mars’ warm, habitable era. The presence of these minerals points to a possible ancient carbon cycle, akin to Earth’s. Scientists estimate up to 36 millibars of CO₂ could have been trapped in rock layers planetwide. These insights also have Earth-based implications: understanding Mars’ natural carbon sequestration helps researchers refine methods to store human-made CO₂ in rock to combat climate change, highlighting the delicate balance that sustains planetary habitability.
