Eruptions from the sun are shortening the lives of satellites in Earth orbit, particularly large constellations like SpaceX’s Starlink—which could be both beneficial and a cause for concern. The sun goes through an 11-year cycle of activity, peaking with a period known as solar maximum, which most recently occurred in late 2024.

The Athena lander photographed on its side in a lunar crater. As any space watcher knows, landing on the moon is no easy feat. Of the 58 landings attempted since 1958, only 28 have been successful. The latest attempt by Intuitive Machines of Texas might contain specific lessons for NASA’s ambitions to return humans to the moon under the Artemis program, as well as the future robotic landers that the agency has funded under its Commercial Lunar Payload Services, or CLPS, program.

ジェシカ・フリックは、宇宙に結晶成長炉をつくりたいと考えている。フリックがカリフォルニア州で経営するAstral Materialsは、医療や半導体など多くの分野に活用できる高価値な素材を地球の軌道上で生産する機械設備を開発している。彼女はその夢を、「宇宙で利益を生み出す箱をつくりたいのです」と表現する。 長年にわたり多くの科学者が指摘してきたように、地球の微小な重力下にある軌道の環境は、地球上よりも高品質な製品を生み出す可能性を秘めている。すでに1973年には、電子回路の部品として不可欠な人工結晶の生成実験が米航空宇宙局（NASA）のスカイラブ宇宙ステーションで実施されたが、その後の進展は遅かった。宇宙での生産活動は数十年後のいまも実験の域を出ず、商業化には至らなかった。 それがいま、ようやく変わろうとしている。ロケット打ち上げの低コスト化に加え、完成品を地球に送る新たな手段が開発されたことにより、Astral Materialsのような企業が次々に新規参入を果たし、「宇宙空間での製造（in-space...

Los astrónomos nunca habían visto nada parecido antes: el estallido de algo enorme en lo profundo del espacio. Los telescopios en la Tierra captaron la sorprendentemente brillante e inusual explosión en 2018, observándola mientras se desarrollaba a 200 millones de años luz de distancia. La explosión aumentó de brillo con rapidez e intensamente, mucho más de lo que se espera que ocurra con la explosión de una estrella normal, una supernova, antes de desaparecer.

Another one! Years after it was first discovered, scientists are still struggling to explain a strange space explosion called "the Cow". Now consensus is shifting towards an intermediate mass black hole being the culprit. Story by me in @BBC_Future https://t.co/fCk8ClBTCd
Is the future of manufacturing in space? A host of companies are now developing ways to make things in space, including seed crystals for semiconductors. Coupled with new return capsules, we're entering a potentially exciting era. Story by me in @WIRED https://t.co/7VcEmrMozx
Exclusive: Scientists at a UK agency have announced £56.8m in funding for 21 geoengineering projects over the next five years. They include Earth cooling technologies, marine cloud brightening, and launching a sunshade into space. Story by me in Nature https://t.co/ji45fT3sym
