Earlier sources: 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 ↗524 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier 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.

NASA Opens Applications for Next Class of Flight Directors ↗
The Artemis II flight control team is pictured in the White Flight Control Room in mission control at NASA’s Johnson Space Center in Houston on April 10, 2026, for the splashdown and recovery of the Artemis II mission. Credit: NASA/Robert Markowitz NASA is seeking leaders for one of the most esteemed positions on Earth for human spaceflight: flight director in mission control at the agency’s Johnson Space Center in Houston. This role is critical to advancing American leadership in space exploration, as NASA paves the way for a sustained human presence on the Moon. Applications for new flight d…

A novel, fast, and accurate code for cosmological loop calculations ↗
We introduce neckar, a public code for the one-loop matter and galaxy power spectrum, as well as correlation function, in the Eulerian Effective Field Theory of Large-Scale Structure (EFTofLSS). It is based on the FFTLog expansion, and is designed for fast and accurate parameter inference from large-scale structure data, making it a powerful tool for high-dimensional Bayesian analyses of current and upcoming galaxy surveys. neckar combines several numerical and analytical improvements, including the separation between pre-computable and cosmology-dependent contributions, a semi-analytic treatm…

Big Bang Nucleosynthesis Constraint on $B$-mesogenesis ↗
$B$-mesogenesis is a low-temperature baryogenesis mechanism, that uses $CP$-violation of the $B$ mesons in the standard model to fulfill the Sakharov conditions. It requires a late period of matter domination by a scalar field $Φ$ that decays into $b\bar b$ quarks, reheating the Universe below the QCD phase transition. We investigate the impact of this mechanism on Big Bang Nucleosynthesis, with respect to the reheating temperature $T_{rh}$, and the mass of $Φ$. Injection of hadrons skewing neutron/proton interconversions are the most important effect, followed by neutrino heating from $Φ$ dec…

Dark Energy Survey Year 6 Results: fast and interpretable posterior predictive checks for correlated cosmic probes ↗
We present a fast and numerically stable framework for conducting posterior predictive distribution (PPD) tests of internal consistency in correlated cosmological probes. Our method, developed as a validation check for the Dark Energy Survey (DES) Year 6 combined analysis of weak lensing and galaxy clustering, employs a Gaussian-mixture model to efficiently approximate the high-dimensional PPD and introduces a scalar consistency metric, $Δ_{\rm PPD}$, defined as the fraction of the PPD at lower probability density than the observed data. This method avoids challenges related to calibration and…

PocketSplat: Mobile Gaussian Reconstruction via World-Space Latent Allocatio ↗
Mobile Gaussian reconstruction must satisfy two requirements: the reconstruction model must execute within a device resource envelope, and the resulting Gaussian asset must expose a representation size suited to downstream mobile use. Existing feed-forward Gaussian reconstructors commonly decode dense, image-aligned candidates whose final cardinality is implicitly determined by the input resolution and number of views. We present PocketSplat, a feed-forward framework for budgeted mobile Gaussian asset construction. Given a prescribed output budget, PocketSplat organizes dense geometry-aware la…

Show HN: Our space game has a built-in RISC-V emulator that runs Linux ↗
(Edit: original URL was https://againstallodds.games/ , but we've switched it to https://againstallodds.games/blog/2026/10/03/our-risc-v-emul... in response to user requests for explanation.) We're a tiny indie studio, all with a background in the demoscene and for about 3 years now we're developing a space planet terraforming game called SEEDS - Echoes Beneath the Sands. Our protagonist Naxiah is stranded on a small, desolated planet. You're wor…

Plato benchmark stars I. The initial benchmark sample ↗
The ESA PLATO mission aims to detect and characterise Earth-size exoplanets orbiting bright, late-type stars using high-precision photometry and asteroseismology. Precise stellar parameters of host stars are essential for exoplanet characterisation and model benchmarking. This work defines the PLATO benchmark stars (PBS) catalogue, a comprehensive sample of well-characterised stars designed to support all mission phases. We compiled data from eclipsing and spectroscopic binaries, interferometry, asteroseismology, and large spectroscopic and photometric surveys. Fundamental and atmospheric stel…

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.
