China Tests Stem-Cell Embryos in Orbit to Assess Space Reproduction Feasibility
China conducted an on-orbit study aboard the Tiangong station using artificial embryos made from human stem cells to examine early development in microgravity. The two embryo models (one simulating uterine attachment and another using a microfluidic chip to mimic tissue formation) were cultured for about five days on the Tianzhou-10 supply ship, then frozen and returned to Earth for analysis, with Earth-based controls for comparison. The goal is to understand potential risks to human reproduction during long-term space habitation, not to create real babies in space.

Rare Fireball Dazzles California Skies, SLO County Among Sightings
A rare fireball lit up California skies Sunday night, with San Luis Obispo County observers among those viewing the event. NASA Space Alerts tracked the meteor as it sped about 35,000 mph, traveling roughly 58 miles through the upper atmosphere before disintegrating about 29 miles above Calflax. The American Meteor Society logged more than 230 sightings across California, Arizona and Nevada, with witnesses reporting colors from blue to orange and, in some places, a faint boom accompanying the event.
NASA's Methalox Boom: Florida Tests Gauge Rocket Safety
NASA is conducting controlled detonation tests of methane-oxygen fuel (methalox) at Eglin Air Force Base in Florida to measure blast radius, concussion, and shrapnel distances for rocket-safety purposes. The program unfolds in three series, escalating from about 100 pounds to 2,000 pounds, then up to 20,000 pounds of fuel, with SpaceX having done its own testing but NASA pursuing its independent safety verification (and a bit of spectacle) before any full-scale launches.
NASA Sets Public Briefing on Artemis II Readiness for Crewed Lunar Mission
NASA will hold a 3 p.m. EDT media briefing at Kennedy Space Center on March 12 after completing the Artemis II Flight Readiness Review, outlining progress toward the four-astronaut crewed lunar mission and discussing the performance of the Space Launch System and Orion spacecraft; the live briefing will feature key NASA leaders and frame Artemis II as a stepping stone to sustainable lunar exploration and future Mars missions.
Artemis II set for lunar flyby with four-astronaut crew, launch delayed to April
NASA's Artemis II will send four astronauts around the Moon on a 10‑day test flight aboard the Space Launch System and Orion capsule, marking the first crewed lunar mission in more than five decades. After a fueling‑system issue forced the rocket back to Kennedy Space Center for repairs, NASA moved the launch to no earlier than April. The mission will test life‑support and other deep‑space systems ahead of a lunar landing targeted for Artemis III in 2028. Crew members are Reid Wiseman, Victor Glover, Christina Koch and Canada’s Jeremy Hansen; Koch would be the first woman aboard a lunar mission, and Glover would be the first person of color to do so.
Elon Musk Signals SpaceX Shift: From Mars Settlement to a Moon-Based City
Elon Musk revealed on X that SpaceX is pivoting from a Mars-first goal to building a self-growing Moon city, arguing the Moon could be developed in under a decade while Mars would take 20+ years. The shift comes as Blue Origin has begun demonstrating lunar capabilities and as Musk expands into AI via xAI, with plans that include mass-driver concepts on the Moon to enable in-space construction. The move suggests SpaceX may prioritize near-term lunar development and collaboration with NASA, rather than an immediate push to Mars, even as both destinations remain part of Musk’s broader space ambitions.
Space Reproduction Put on Hold as Experts Warn of Safety Risks
A new report in Reproductive BioMedicine Online warns that reproducing in space is far from safe due to radiation, microgravity, and lunar dust, which may affect fertility, pregnancy, and offspring. It calls for a global ethical framework, better shielding, medical countermeasures, and advanced assisted reproduction tools before any long-duration missions, effectively delaying space births until safeguards are in place.
Meteor Causes Shaking and Loud Booms Over NYC and NJ
A loud boom heard in parts of New Jersey and New York City was likely caused by a meteor fireball flying about 49 miles above Upper Bay near Jersey City, traveling at 34,000 miles per hour, and disintegrating 29 miles above Midtown Manhattan. NASA's Meteoroid Environments Office confirmed the event, while the US Geological Survey found no evidence of an earthquake. No meteorites were produced, and there were no reported impacts to the city.
Meteor Explodes Over NYC, Causes Shaking and Loud Booms
A meteor exploded over Manhattan after flying over the Statue of Liberty at a speed 58 times faster than a Boeing 737, causing loud booms heard in New York and New Jersey. NASA and other authorities are uncertain if the booms were caused by the meteor or military activity, but no damage or injuries were reported. Despite the dramatic event, many New Yorkers remained unfazed.
"Strong Solar Flares Trigger Radio Blackout Warnings"
Multiple sunspot regions on the Sun are currently active, producing strong solar flares that have caused radio blackouts on Earth. NOAA's space weather forecasters are monitoring these regions closely as the Sun approaches its Solar Maximum. The new GOES-19 satellite, set to be operational by spring 2025, will enhance solar storm forecasting capabilities.
Astronauts Capture Mysterious Glowing Orbs and Red Sprites from Space
NASA astronaut Matthew Dominick captured a photo of glowing blue orbs, known as red sprites, from the International Space Station. These orbs, caused by thunderstorms off the coast of South Africa, are a rare atmospheric phenomenon that appear above storms due to lightning. The photo, taken on June 3, offers a rare glimpse of these high-altitude lightning events, which are difficult to capture from Earth. NASA encourages citizen scientists to contribute their own photos of sprites to the Spritacular database for research purposes.
