Gilmour Space *might* be launching their Eris rocket (and its Vegemite payload) right now. 🚀

The launch window is open, but there's no official livestream or other live updates. We just have to wait a few hours for an announcement about whether they launched, and if they went to space today.

Generic (English) — Astronaut
NASA — Astronaut
Roscosmos — Cosmonaut
CNSA — Taikonaut
ISRO — Vyomanaut

Officially, ESA uses astronaut, but what would you call them? Wiktionary.org lists spationaut.

They follow a pattern of a space-related word truncated to 2 syllables followed by the suffix "-naut".

It's important that the word (or some variation of it) is understood and pronounceable by as many EU citizens as possible.

The Orbital Index Issue № 328:
The Vera C. Rubin Observatory is now operational, aiming to reshape our cosmic understanding with its massive 8.4m mirror and cutting-edge camera. South Korea is pushing for lunar missions and reusable rockets, while NASA's budget holds steady at $29.9B. SES acquires Intelsat, and Blue Origin gears up for the ESCAPADE mission. 🚀🌖🛰🌌📡🌍💫

"Torqued Accelerator using Radiation from the Sun (TARS) for Interstellar Payloads arxiv.org/abs/2507.17615"

arXiv.orgTorqued Accelerator using Radiation from the Sun (TARS) for Interstellar PayloadsThe concept of exploring space using solar power is energetically appealing, but interstellar solar sails typically require extremely low areal densities (~0.8 g/m^2). This work explores an alternative approach: storing solar energy as rotational kinetic energy, which is later released to propel a microprobe beyond the solar system. The proposed Torqued Accelerator using Radiation from the Sun (TARS) consists of two thin surfaces with contrasting albedos that gradually spins up over weeks to months while in a sub-Keplerian "quasite" orbit around the Sun. Though constrained by material strengths, careful design allows a phone-sized payload to reach interstellar velocities in less than a year, using commercially available materials (e.g. CNT sheets). The entire system spans tens of meters and weighs of order of a kilogram. Whilst there is no theoretical limit to the achievable speeds, practical designs grow exponentially in size as velocity targets increase, making interstellar flight feasible but relativistic speeds implausible. Several strategies, including the use of graphene sheets, gravity assists, the Oberth effect, and electrostatic confinement, could further maximise velocity. TARS is an attractive light sail technology when high-powered directed energy systems are impractical, offering a potentially low-cost solution for deploying small, sub-relativistic interstellar probes.
