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. […]

Members Newsletter – February

22 February 2025

Guest News Item: Missions to 2024 YR4 by Adam HibberdA newly discovered asteroid, 2024 YR4, has been identified by the Asteroid Terrestrial-impact Last Alert System (ATLAS) and currently has an estimated 2.1% chance of impacting Earth on December 22, 2032 [1,2]. This presents a unique opportunity to apply my software, Optimum Interplanetary Trajectory Software (OITS) […]

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 – […]

What’s up with 1998 KY26?

1 June 2026

Adam Hibberd I’m not sure whether you might already be aware of this but there are really weird objects orbiting the Sun which astronomers have observed and tried to categorize as a new class of object, ‘the dark comets’. But what makes them weird? It’s the rather strange fact that the peculiar orbital paths they […]

Mission to an Interstellar Object

5 May 2026

Adam Hibberd Many readers in-the-know will have heard of the future ESA ‘Comet Interceptor’ mission, due to launch in 2029. For those not-in-the-know it is a spacecraft desgined to loiter at the famous Sun/Earth Lagrange 2 (L2) point for a few years, waiting for a ‘pristine’ Oort Cloud comet to come flying in to the […]
