Artemis Three test plan & Four launches in one day - Space News (Oct 24, 2026)

A canyon on Mars that formed billions of years ago is not entirely still. A quake traced beneath it suggests that ancient faults on the Red Planet can continue moving today. Welcome to The Automated Daily, space news edition. The podcast created by generative AI. I’m TrendTeller, and today is October 24th, 2026. In this edition, NASA maps out an unusually complex rehearsal for future Moon landings, four rockets reach orbit in a single day, and researchers eliminate one of the more extreme candidates for dark matter. We’ll also look at a new listening post in the search for alien technology and the surprisingly colorful remains of dead stars.

Artemis Three test plan

We begin with NASA’s evolving route back to the Moon. The agency has presented new details for Artemis Three, a roughly two-week mission planned for 2027. Rather than landing astronauts on the lunar surface, the crew would remain close to Earth and practice working with test versions of two competing Moon landers. The plan calls for NASA’s Orion spacecraft to meet and dock separately with vehicles developed by Blue Origin and SpaceX. Astronauts would evaluate how people enter, occupy and operate these systems before either design carries a crew near the Moon. Three major rockets would be involved, making this an unusually demanding launch campaign even though the activity would happen in Earth orbit. The significance is risk reduction. NASA wants to discover integration problems close to home rather than during a lunar mission, while also keeping both lander programs moving toward a possible surface return in 2028. The schedule remains ambitious, and an exact launch date has not been fixed, but the agency now has a clearer rehearsal plan for one of the hardest parts of Artemis. [32][34][41]

Four launches in one day

It was also a crowded Friday for launch teams around the world, with four missions reaching orbit on October 23rd. Rocket Lab launched three HawkEye 360 satellites from New Zealand. Those spacecraft are designed to locate and study radio transmissions from orbit, with applications ranging from maritime tracking to detecting navigation-signal interference. China conducted two launches of its own. A Long March Six A carried the Yaogan 50-03 remote-sensing satellite, while a later Long March Four B flight deployed another group of Yaogan spacecraft. Public descriptions of the Yaogan program emphasize Earth observation, although independent launch databases commonly associate many of these missions with military reconnaissance. The day concluded with a Falcon 9 launch from California carrying another group of Starlink satellites. No single flight transformed spaceflight, but the combined pace is the story. Four launches from three countries and widely separated spaceports within one day show how orbital activity is becoming a continuous global operation rather than a sequence of rare events.

Giant black holes and dark matter

Now to dark matter, where scientists have ruled out a particularly enormous possibility. One proposal held that some dark matter might be concentrated in primordial black holes with masses greater than whole galaxies. These hypothetical objects have been called stupendously large black holes, which is unusually direct language for astronomy. Researchers tested the idea using the cosmic microwave background, the ancient light left over from the early universe. If a meaningful share of dark matter had been packed into a relatively small number of colossal black holes, matter in the young cosmos would have been distributed unevenly. That should have left a detectable graininess in this background light. The expected pattern is not there. The result means black holes of such extreme size cannot make up a major fraction of dark matter. It does not prove that none exist, and it does not eliminate much smaller primordial black holes. Still, it closes off one dramatic part of the search and helps researchers concentrate on candidates that better match what the universe actually shows us. [46][52]

Mars canyon remains active

On Mars, researchers have found evidence that an ancient geological scar is still capable of moving. Scientists reexamined a marsquake recorded by NASA’s InSight lander in 2021 and traced it to Valles Marineris, the enormous canyon system that cuts across the Martian surface. Their analysis indicates that rocks slipped along a fault deep beneath the western part of the canyon. Valles Marineris formed billions of years ago, when Mars was more geologically active. The new result suggests that faults created during that distant period can remain weak enough to move under present-day stresses. This does not mean the entire canyon is changing rapidly, or that Mars has Earth-like plate tectonics. It does mean the planet is not as mechanically quiet as its surface might suggest. That matters for understanding how rocky planets lose heat and evolve after their most active years. It may also help scientists identify regions where future seismic instruments could learn more about the Martian interior. [76][77][82]

Asia joins the LaserSETI network

The search for possible signals from alien technology has gained a new observing location. Two LaserSETI detectors are now operating at AlUla in northwestern Saudi Arabia, making this the network’s first site in Asia and its fifth location worldwide. Unlike searches that repeatedly point a telescope at selected stars, LaserSETI watches broad areas of the sky for very short flashes of light. A sufficiently narrow and powerful laser pulse could be a sign of technology, although natural astronomical events and human-made interference are more likely explanations for most detections. Adding an Asian station improves both sky coverage and verification. If instruments at distant sites detect the same flash, researchers have a better chance of showing that it came from space rather than from a local aircraft, satellite or electronic disturbance. No alien signal has been found. The important development is that the observing network now has a wider geographic reach and can watch more of the sky for rare events, whether artificial or natural.

White dwarfs reveal unexpected colors

Finally, white dwarfs may deserve a more colorful name. These compact remnants of Sun-like stars are generally described as white, but researchers have modeled how their light would appear to nearby human eyes. The answer includes shades of green, pink, purple, yellow and cyan. The differences come from the dense atmospheres of the stars. Carbon can push their apparent color toward pink or purple. Hydrogen and helium can create a pale blue or cyan appearance. Material left from shattered asteroids and planets can also alter the light. One especially unusual white dwarf would appear chartreuse green. Researchers say sodium from rocky debris absorbs part of its orange light, leaving the green tint behind. These colors cannot be seen directly from Earth because the stars are too distant to resolve as discs, so the team calculated them from their spectra and models of human vision. Beyond the appealing palette, color provides clues about what happened after these stars died. Their atmospheres can preserve traces of former planetary systems, turning stellar color into evidence about the remains of distant worlds. [106][109]

That’s today’s tour of space and astronomy: a safer rehearsal for returning to the Moon, a busy day in orbit, a dark-matter idea placed under tighter limits, and reminders that both planets and dead stars can remain more active and varied than they first appear.
