THE INTERNET IS THINKING
Space
Space research and engineering study the universe and build the systems used to reach and observe it. Follow astronomy, spacecraft, launch systems, satellites, exploration, and Earth observation.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗495 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Recent sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Show HN: Netsat, a shared internet virtual satellite you can use to learn DSP ↗
Receiving and decoding satellites is (in my opinion) one of the coolest things you can do with a radio. The problem is that it has a steep learning curve. Protocols are complicated, signals are hard to catch and track, and requires an investment in equipment just to get started. Netsat is an internet stream that simulates the experience of receiving a satellite signal with an SDR. I simplified the physics quite a bit to make it easier to get star…

NASA Names Stephen Cash Marshall Space Flight Center Director ↗
Photo of Stephen Cash NASA Administrator Jared Isaacman has named Stephen Cash director of the agency’s Marshall Space Flight Center in Huntsville, Alabama, effective Monday, Oct. 19. Cash, a veteran NASA engineer and aerospace executive, returns to lead the center where he began his career more than four decades ago. “Marshall contributions to NASA’s missions are historic and it’s no question why it’s the Center of Excellence for propulsion,” said Isaacman. “Steve Cash is a Marshall legend, has spent his career around the hardware, the people and has been in the seat before making the decisio…

Artemis II Heat Shield After Splashdown ↗
US Navy Shortly after NASA’s Artemis II mission splashed down on April 10, 2026, U.S. Navy divers captured underwater imagery of the Orion spacecraft’s heat shield. In the months after, the agency measured whether the thermal protection system effectively safeguarded the crew and Orion systems as the spacecraft reentered Earth’s atmosphere. This rigorous analysis confirmed that the heat shield performed as expected. Learn how Orion’s heat shield was examined. Image credit: US Navy

NASA to Help Unlock Mysteries of Mars’ Moons in Upcoming Mission ↗
NASA is playing an important role in JAXA’s (Japan Aerospace Exploration Agency) MMX (Martian Moons eXploration) mission, to advance our understanding of Mars’ moons and build on the agency’s long history of exploring the Red Planet. The mission aims to characterize and determine the origin of Mars’ moons Phobos and Deimos and deliver a sample of Phobos to Earth. The MMX spacecraft is targeting launch from JAXA’s Tanegashima Space Center in Japan at 3:41 p.m. EDT on Monday, Oct. 19 (4:41 a.m. JST on Tuesday, Oct. 20). An artist’s concept of JAXA’s MMX spacecraft during its Mars’ orbit insertio…
Live window recorded . This is the ingestion observation time, not the publication or discovery date of each source.
How to assess evidence about Space
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
