@i4interstellar.bsky.social My latest blog details how my software works at a basic level, and explains how I used it to solve the problem of sending a mission to catch the interstellar object 1I/'Oumuamua: adamhibberd.com/2026/02/07/h...

We're posting here content from older newsletters, join us at www.i4is.org/members for the latest. Dec-25 [2] : this content is already here on Bluesky, see below. The authors describe self-consistent scenarios for future Earth technospheres as analogs for extraterrestrial technospheres....

As elsewhere, we'll post here content from older newsletters, join us at www.i4is.org/members for the latest. Dec-25 [1] : A paper by Colin Snodgrass describes how the ESA Comet Interceptor can provide a conceptual basis for a future mission to visit an Interstellar Object arxiv.org/abs/2512.00492

We're not sure about the science, but Mike McCulloch has spoken on QI at our events in the past ... and if he's right, interstellar travel becomes much easier !

Here's an interesting concept that promises 'easy interstellar propulsion' ...

This describes five ideas for interstellar travel. As a spoiler, in summary... - Brute-force 'Project Daedalus' - Laser Sail - Bussard Ramjet - Antimatter 'Project Valkyrie' - the 'Light Hugger' Other concepts involve breaking physics, these (just) avoid that. Comments? youtu.be/xJSO-ptwYxw?...

Here's an interesting paper by our member @adamsspaceresearch.bsky.social et al. There's been criticism that it proposes alien origin for 3/Atlas, but it says that is not so : it's an academic exercise mentioning our habit of seeing pattern in randomness. Please comment! arxiv.org/abs/2507.12213

Go to my starshp blog for i4is which can be found here: i4is.org/wp-admin/pos... It raises a hypothetical question and mentions the various evidence in favour. It emphasises that the investigations are merely a pedagogical exercise. @i4interstellar.bsky.social Preprint: arxiv.org/abs/2507.12213

Here's a recent video from @hoojiwana.bsky.social talking about the recent 'Pulsar Fusion' publicity. Are his conclusions correct ? Or will Pulsar take us to the stars ? Comments are welcome !!

This could be interesting, especially if @adamsspaceresearch.bsky.social can find a good spacecraft rendezvous option ...

Inflatable sails offer steep savings in mass & enable larger payloads. I look today at deep space concepts involving this technology, & new studies on using inflatable structures for exoplanet research via a starshade. www.centauri-dreams.org/2025/06/11/i...

From 2024, here's the Project Lyra* mission guide by @adamsspaceresearch.bsky.social in a starship blog on our website. i4is.org/project-lyra... * Project Lyra is the study of missions to chase down the interstellar object 11/'Oumuamua, in order to determine once and for all what this thing is...

This is everywhere in the news today ... "The Cambridge group has found that the atmosphere seems to contain the chemical signature of at least 1 of 2 molecules... associated with life: dimethyl sulphide and dimethyl disulphide. On Earth ... produced by marine phytoplankton and bacteria."

Again, a fusion-powered interplanetary spacecraft would be good for Interstellar precursor trips, and the technology could be developed for true Interstellar missions.

Here are videos from the recent Symposium... "... keynote presentations ... tackling the challenges of humanity’s journey to the stars ... propulsion breakthroughs, astrobiology, long-duration missions ... dive deep into the technologies, ethics, and aspirations... " youtube.com/playlist?lis...
