Direct Missions to ‘Oumuamua

16 May 2025

Adam Hibberd There has been a lot of discussion around what would be the best route to catch that most mysterious and outrageously quirky interstellar interloper 1I/’Oumuamua, and I have personally investigated all sorts of spacecraft mission scenarios; using a combination of gravity assists (where kinetic energy is gained by the spacecraft’s encounter with a […]

Presentation for the British Interplanetary Society on Missions to 2024 YR4

8 April 2025

Adam Hibberd An asteroid was discovered in December 2024 which for a while had the world on tenter hooks. Its predicted path brought it in close proximity to the Earth in December 2032, with a chance of collision which steadily rose to around 3% over the course of several weeks. Now all the pressure valves […]

The Importance of Exploration

2 April 2025

Adam Hibberd I have recently read a review of a book titled “Astrotopia: the Dangerous Religion of the Corporate Space Race” written by a professor Mary-Jane Rubenstein and it is reviewed by Patrick Mahon, who is on the Board of Directors for i4is. The review can be found here. You might be interested in that […]

2024 YR4: A Continuing Menace

28 February 2025

Adam Hibberd Now the threat posed by Potentially Hazardous Asteroid (PHA) 2027 YR4 to Earth in December 2032 has been effectively ruled out altogether, an apathy concerning this object has descended on so many and this is, of itself, quite alarming. Let me explain to you TWO reasons now why such complacency is entirely misplaced. […]

2024 YR4 Battle Plan

18 February 2025

Adam Hibberd The asteroid 2024 YR4 will approach pretty close to Earth on 2032 December 22nd and we can’t yet preclude a Tunguska-scale impact. Unlike Tunugska however, there would be quite a high likelihood of human fatalities, since its impact location could coincide with quite densely populated areas including India, for example, certainly a disaster […]

The Impact Energy of 2024 YR4, a Mission of Gravity

9 February 2025

Adam Hibberd Recently I’ve been pondering a problem of gravity. Specifically, the gravity of a particular celestial object which has come to the world’s attention, making headline news in certain papers, I am of course talking about the potentially hazardous asteroid (PHA) designated 2024 YR4. This object has an orbit which could – potentially – […]

2024 YR4 and Sample Return Missions

3 February 2025

Adam Hibberd Today it was back to potentially hazardous asteroid (PHA) 2024 YR4 which was discovered quite recently and has a comparatively high chance (depending on the source ~ 1.3%, with some sources quoting higher probabilities) of colliding with Earth in 2032. Furthermore this collision has the potential of causing many human deaths, though I […]

Tunguska and the Case of Asteroid 2024 YR4

29 January 2025

Adam Hibberd The Tunguska event holds a special place in humanity’s collective memory as an incident which could have been so much more devastating had it not occurred in the heavily forested area of Siberia and instead in a more densely populated area . Yes trees were flattened yet it seems for this event at […]

Solar Sailing as a Precursor to Proxima Centauri

4 January 2025

Adam Hibberd I think most of you know me by now as the guy who developed the tool called ‘Optimum Interplanetary Trajectory Software’ (OITS) which ultimately solved the problem of how we might send a spacecraft to catch up with rapidly receding interstellar object and scientific enigma ‘Oumuamua. I decided to work on OITS – […]

A Precursor Mission to Proxima Centauri

31 October 2024

A Mission to Five Near Earth Objects in 2030 Adam Hibberd We at i4is, together with our collaborators on the Phase I NIAC (NASA Innovative Advanced Concepts) at Space Initiatives Inc., have been contemplating precursors to the ultimate mission of sending laser sails to swarm our nearest neighbouring star, Proxima Centauri. A summary of the […]

Deflecting Apophis

26 October 2024

Adam Hibberd There have been some developments. I have been addressing the problem of how to deflect Apophis from its path if it were indeed on a collision course with Earth. My Apocalypse Plot gives the magnitude of ΔV at different points in Apophis’s orbit to send it on a course to JUST strike the […]

Apophis: More Monolythical Mathematical Musings.

29 September 2024

Adam Hibberd Apophis gets awfully close on Friday April 13th 2029 (within GEO altitude). Its orbit is altered by the encounter with Earth and the obvious question is will there be any further possible encounters? Some of you may remember I have worked on the practicalities of sending laser-accelerated sails to intercept Apophis as it […]

Halley Rendezvous – the problem of how to get to the comet and stay there.

10 September 2026

Adam Hibberd A rendezvous mission to Halley’s comet? The return visit of Halley to the inner solar system won’t be until around 2061, with perihelion on July 28 of that year. That’s a long way away, right? That hasn’t stopped some scientists deriving a trajectory to this well-known comet, designed to RENDEZVOUS with it (go […]

Members Newsletter – August

28 August 2026

Interstellar Symposium: Register Now! The Interstellar Research Group (IRG) is pleased to announce that registration is now open for the 2nd European Interstellar Symposium, taking place December 2 to 4, 2026, in Venice, Italy. This special symposia is hosted by The Venetian Institute of Sciences, Letters and Arts in association with The Interstellar Research Group and […]

How long does it take to get to the Sun/Earth L4 Point from Earth?

18 August 2026

Adam Hibberd Let’s say we eject a spacecraft with a small velocity decrement in the opposite direction to Earth’s own velocity around the Sun, what will happen to it exactly? It will stay around Earth’s heliocentric orbit since its velocity is close to Earth’s, however we shall assume that the spacecraft flies outside of Earth’s […]

What is 1998 KY26?

6 August 2026

Adam Hibberd I was recently referred to a paper by Farnocchia et al which apparently, so was it argued, contradicted the notion that 1998 KY26 could be technogenic (man made), in other words a spacecraft. For the uninitiated, 1998 KY26 has always been considered (up-to-recently at least) a Near Earth Asteroid (NEA) of some form […]
