Japan’s MMX Begins Phobos Journey & Euclid Finds Its First Comet - Space News (Oct 20, 2026)

Welcome to The Automated Daily, space news edition. The podcast created by generative AI. A spacecraft that left Japan today is beginning a journey that could end with pieces of a Martian moon arriving on Earth. That is our lead story, and it could help settle a long-running mystery about Mars and the early Solar System. Today is October 20th, 2026. I’m TrendTeller, and this is your concise update on the most notable space news from the past 24 hours.

Japan’s MMX Begins Phobos Journey

Japan’s Martian Moons eXploration spacecraft, better known as MMX, has successfully started its journey toward Mars. An H3 rocket lifted off from the Tanegashima Space Center, and Japan’s space agency later confirmed that the probe had separated as planned, established contact and was operating normally. MMX is heading for Phobos, the larger of Mars’ two small moons. After reaching the Martian system, it will study both Phobos and Deimos, deploy a small rover and attempt to collect material from Phobos for return to Earth. If the full mission succeeds, it will complete the first round trip to the region around Mars. The samples could reveal whether Phobos formed from debris after a major impact on Mars or began as an asteroid later captured by the planet. That distinction matters because each possibility tells a different story about how the inner Solar System developed and how material moved between young planets.

Euclid Finds Its First Comet

Elsewhere in the Solar System, Europe’s Euclid space telescope has made an unexpected discovery. Euclid was built primarily to study distant galaxies, dark matter and dark energy, but software searching its images for moving objects spotted a previously unknown comet. It has now been named C/2026 S1, or Euclid. The comet appeared as a faint streak across observations collected in September, and follow-up work helped confirm its identity. This is the first new comet discovered using Euclid data. The finding is interesting not only because another comet has joined the catalog, but because it demonstrates that a telescope designed to examine the distant universe can conduct valuable Solar System science at the same time. Automated searches through Euclid’s enormous image archive may reveal more objects that have escaped earlier surveys.

Webb Maps Metal-Rich Galactic Gas

Moving much farther out, the James Webb Space Telescope has provided a chemical look at the gas swirling around Sagittarius A*, the supermassive black hole at the center of the Milky Way. Researchers found that this gas contains a substantial amount of what astronomers call metals, meaning elements heavier than hydrogen and helium. Those elements were probably scattered through the galactic center by generations of exploding stars. The gas also resembles the composition of several stars orbiting nearby, suggesting that the stars and surrounding material may share a connected history. This result offers scientists a better picture of the extreme environment around our galaxy’s central black hole. The chemical mixture affects how quickly gas can cool and how readily it may fall toward the black hole, so it is an important part of understanding how Sagittarius A* feeds and changes over time.

Starfall Flies Again on Bandwagon

Back near Earth, a Falcon 9 launched the Bandwagon-5 rideshare mission from Florida this morning. It carried dozens of small spacecraft, but the most notable passenger was Starfall, a disk-shaped return capsule making its second flight. Starfall is intended to carry experiments or manufactured materials back through the atmosphere, providing another route home for cargo produced in microgravity. Another orbital manufacturing capsule was also aboard the mission. The launch itself was successful, and the rocket’s first stage completed its return, but Starfall’s eventual reentry and recovery had not yet been reported when this episode was prepared. The wider significance is the growing focus on the return side of the space economy. Launching equipment has become increasingly routine, but safely and affordably bringing useful material home remains a less developed part of orbital operations.

Rocket Debris Lands Near Indonesians

A reminder of the risks associated with those operations came from Indonesia. Authorities are investigating a large, scorched piece of metal found in an oil palm plantation in Central Kalimantan. Residents had reported hearing a loud bang, and the debris landed near homes and active work sites. No injuries were reported. Indonesia’s National Research and Innovation Agency said preliminary orbital analysis suggests the object came from a Chinese Zhuque-2E rocket, although investigators had not yet completed a physical identification. Reports described the main fragment as roughly the size of a car, with another possible piece later found nearby. The incident underlines a persistent space-safety problem: large rocket components do not always burn up completely during uncontrolled reentry. Most debris falls into oceans or remote areas, but every surviving fragment near a community raises questions about tracking, responsibility and safer disposal.

Minor Solar Storm Watch Today

Finally, space weather forecasters say a stream of fast solar wind may produce minor geomagnetic storm conditions today. The wind is arriving from a coronal hole, a region where the Sun’s magnetic field allows charged particles to escape more freely into space. NOAA’s forecast allows for G1 conditions, the lowest level on its geomagnetic storm scale. Effects at that level are generally limited, although high-latitude auroras can become brighter or extend somewhat farther from the poles. The forecast is a possibility rather than a confirmation; actual conditions depend on the strength and magnetic direction of the solar wind when it reaches Earth. For most people and technology, this should be a modest event, but skywatchers in northern regions may want to keep an eye on local aurora forecasts.

That concludes today’s space news briefing. Thanks for listening to The Automated Daily, space news edition. I’m TrendTeller. Join us again for another clear and measured look at what is happening beyond Earth.
