Despite last-minute setbacks, NASA hopes that the Orion spacecraft will soon take four people on the furthest journey in the history of humankind. In this interview, one of the vehicle’s designers explains how it was made. At the beginning of this week, the Artemis II rocket was sitting on the launch pad at NASA’s Kennedy
Summary: Forming a long-term memory is an energy-intensive process that requires neurons to produce a massive amount of fuel (ATP). A new study has discovered a way to “overclock” this energy production to significantly boost memory. By inhibiting a protein called LETM1, which exports calcium from mitochondria, researchers were able to keep calcium inside the
Veteran NASA astronaut Mike Fincke has confirmed that he was the crew member who had a concerning “medical event” that led to an early exit from the International Space Station last month. Fincke and his fellow crewmates — NASA astronaut Zena Cardman, Kimiya Yui of the Japan Aerospace Exploration Agency, and cosmonaut Oleg Platonov of
It has been billed as China’s first emergency operation in the country’s human spaceflight program. The three astronauts (or taikonauts) of China’s Shenzhou-20 mission were originally slated to return to Earth last Nov. 5, but after discovering cracks in the viewport of their spacecraft, their landing was postponed. Chen Dong, commander of the Shenzhou-20 crew,
NASA astronaut Mike Fincke, the commander of the International Space Station, revealed that he was the crew member whose medical issue required a group of space station fliers to cut short their mission and return early to Earth in January. Fincke, 58, did not provide details about the medical issue nor his current health status,
Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the

A newly released plot of the Hubble Space Telescope’s altitude shows just how quickly the observatory has descended in recent years. The post on Bluesky by astronomer Jonathan McDowell is a stark reminder that Hubble is heading back to Earth, possibly sooner than previously thought, as its orbit decays. Hubble was launched into low Earth
Here on Earth, it seems easy and straightforward to know “where” anything is, or to know “when” an event either occurred or will occur. After all, we’ve mapped out the entire surface of the Earth, and can define our location with three coordinates — latitude, longitude, and altitude/depth — no matter where in the world
