Here are some recent space-related stories of interest.

—GeekWire: “Rubin Observatory Sends Out Thousands of Data Alerts with an Assist from Seattle Astronomers“

An astronomical alert system developed at the University of Washington started off with a bang this week, sending out 800,000 notifications about moving asteroids, exploding stars and other celestial changes detected by the Vera C. Rubin Observatory in Chile. Tuesday night’s surge was just the first wave of alerts. Eventually, the Alert Production Pipeline is expected to produce up to 7 million alerts per night. Astronomers around the globe will use the system to sift through the torrent of data, zeroing in on events ranging from newly detected asteroids to supernovas, variable stars and active galactic nuclei.

—Sky&Telescope: “Get Ready for the March 3, 2026, Predawn Total Lunar Eclipse“

On Tuesday, March 3rd, the full Moon glides through the darkest portion of Earth’s shadow, called the umbra, to create a dramatic total lunar eclipse. In the Western Hemisphere, the event occurs in the hours before dawn, while across Asia it happens during the evening. During the eclipse, Earth’s shadow is seen gradually edging across the face of the full Moon until the entire lunar disk glows deep orange or red. Then the sequence of events unfolds in reverse order, until the shadow leaves the lunar disk completely and the Moon returns to full brilliance.

—Futurism: “Astronomer Who Discovered Water on Distant Planet Murdered Outside Home“

A renowned Caltech astronomer who studied distant exoplanets was shot and killed outside his home in a rural area near Los Angeles, the LA Times reported…Among his most notable contributions to the field was leading research published in 2007 that, for the first time, captured enough light from distant exoplanets to identify the molecules in their atmospheres…and soon made the “monumental” discovery of detecting signs of water on another planet.

Space Quote: New Artemis Mission Added Before Moon Landing

Posted on by onespaceman2000

“You don’t go from one uncrewed launch of SLS [Artemis I], wait three years, go around the Moon [Artemis II], wait three years and land on it…I would certainly much rather have the astronauts testing out the integrated systems of the lander and Orion in low-Earth orbit than on the Moon.”

-Statement by NASA Administrator Jared Isaacman regarding the addition of one more Artemis mission – let’s call it Artemis III-A – to test out the lunar lander before the crew actually heads to the Moon – or Artemis III-B. The Moon landing itself is still planned for 2028, but we know how these dates continue to slip. SpaceX with its Starship issues is not making it any easier. Just like SpaceX saved the Starliner crew from a problem Boeing capsule, Blue Origin may eventually save the Artemis astronauts from a problem SpaceX rocket.

Note: Actually, I think it will just be an uncrewed Artemis III mission followed by the first Moon landing as Artemis IV, but for some reason I think we will be adding even more Roman numerals before we hit the Moon. Maybe we will get to X, Musk’s favorite letter, before we approach the Moon.

Now We Know the Rest of the Story about that ISS Medical Emergency

While NASA had kept it quiet for a while, we now know that the medical evacuation of Crew-11 from the International Space Station (ISS) last month related to NASA astronaut Mike Fincke (age 58).

While we still do not know the underlying medical condition, and maybe never will, it appears Fincke is still recovering given that he has stated:

I’m doing very well and continuing standard post-flight reconditioning at NASA’s Johnson Space Center in Houston. Spaceflight is an incredible privilege, and sometimes it reminds us just how human we are…Thank you all for your support.

It is good that he reminds us of human frailty as we send manned spacecraft to the Moon again, while also contemplating the daunting task of sending humans to Mars.

We were reminded of human frailty again this past weekend when a US Navy sub had to resurface near Greenland because of crew member’s medical condition. A submarine submerged for months at a time is probably as close as you will get to the conditions and isolation of a spacecraft going to Mars.

Note: An interesting fact about Mike Fincke is that he appeared as a guest star on the last episode of Star Trek: Enterprise in 2025. He played the part of Lt. M. Fincke.

Space Stories: More Artemis II Delays, Starliner a Type A Mishap, and James Webb Space Telescope Studies Atmosphere of Uranus

Here are some recent space-related stories of interest.

—NPR: “NASA’s Artemis II Lunar Mission May Not Launch in March After All“

Just one day after NASA said it was eyeing a potential March 6 launch date for the Artemis II lunar mission, the space agency said Saturday that complications with the rocket could delay all launch attempts in March from the Kennedy Space Center in Florida...In a blog post, NASA said it is “taking steps to potentially roll back the Artemis II rocket and Orion spacecraft to the Vehicle Assembly Building,” after technicians observed an “interrupted flow of helium” to the rocket system. NASA says its teams are “actively reviewing data” and taking steps to “address the issue as soon as possible while engineers determine the best path forward.”

—Astronomy Magazine:“NASA Report Declares Starliner Incident a Type A Mishap“

On Thursday, NASA released sobering results from an independent investigation into the 2024 crewed Boeing Starliner test flight that left two astronauts stranded in space for months, placing blame not only on hardware failures, but the agency’s own leadership and culture. In a press conference, NASA Administrator Jared Isaacman said the agency had now categorized the incident as a type A mishap — the same classification applied to the Columbia and Challenger shuttle disasters — something he believes should have happened from the start.

—European Space Agency: “Webb Maps Uranus’s Mysterious Upper Atmosphere“

For the first time, an international team of astronomers have mapped the vertical structure of Uranus’s upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using NASA/ESA/CSA James Webb Space Telescope’s NIRSpec instrument, the team observed Uranus for nearly a full rotation, detecting the faint glow from molecules high above the clouds. The results offer a new window into how ice-giant planets distribute energy in their upper layers.

Pic of the Week: A Protostar in the Cepheus A Region

This week’s image was taken by the Hubble Space Telescope. It shows the star-forming region Cepheus A in the constellation of Cepheus. This region is about 2,400 light-years away.

Here is more from NASA about this region:

The high-mass star-forming region Cepheus A hosts a collection of baby stars, including one large and luminous protostar, which accounts for about half of the region’s brightness. While much of the region is shrouded in opaque dust, light from hidden stars breaks through outflow cavities to illuminate and energize areas of gas and dust, creating pink and white nebulae. The pink area is an HII region, where the intense ultraviolet radiation of the nearby stars has converted the surrounding clouds of gas into glowing, ionized hydrogen.
