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 […]

Adam Hibberd I have recently returned my attention to the Solar Oberth mission to ‘Oumuamua. For readers not familiar with this celestial body, 1I/’Oumuamua was the first interstellar object to be discovered passing through our Solar System, is now out of range of our most powerful telescopes and has left scientists with many questions in […]

Adam Hibberd Breakthrough Starshot is the Initative to send a probe at 20% light speed (0.2c) to the nearest neighbouring star Proxima Centauri. But how do we achieve such a high speed? It turns out that if we have an extremely powerful laser (and exponential advances in tech over the next decades will mean that […]

Adam Hibberd In my last post I explained how my software development, Optimum Interplanetary Trajectory Software (OITS), seems to achieve miracles of intelligent design in a fashion analogous to evolution, though in fact with both cases evidently no intelligence is involved – instead simple mechanisms combined with iteration are at work. This concept stimulated me […]

Adam Hibberd The more I think about evolution through natural selection the more I see analogues to my software development Optimum Interplanetary Trajectory Software. (I should make it clear at this early stage in my post that OITS does NOT employ a genetic/evolutionary algorithm approach, I shall elucidate below.) You see there is NO intent […]

Adam Hibberd A view of the distance of ‘Oumuamua from each of the Inner Planets as it rounded the sun, reached perihelion and then sped away again. Mars was just about as far away as it could possibly have been from ‘Oumuamua. ‘Oumuamua came very close to Earth (around 0.16 au). It came no closer […]

Adam Hibberd Let me tell you all a story. It is the story of life and its purpose. I ask you to bear with me here as Project Lyra and ‘Oumuamua will make an appearance eventually – I promise. Many of you will be familiar with the idea that the universe might be some kind […]

Adam Hibberd Those of you who have been following my Project Lyra blogs know that I have over the past year or so done some extensive analysis of ‘Oumuamua’s trajectory. You may refer to previous posts on the i4is website to get an understanding of exactly what I have been up to, or alternatively continue […]

Adam Hibberd Here’s a mission to asteroid Psyche for you. Initial theories favoured Psyche as a core of a failed protoplanet, containing vast reserves of metals. More recent research, however favour alternative origin theories. Whatever is the case, we are about to discover its true nature and this would be a huge step forwards for […]

Adam Hibberd Wouldn’t you like an answer to the question: What is ‘Oumuamua? There have been many theories, but there is no real consensus. The only way to answer this would be to send a spacecraft to observe ‘Oumuamua in situ but the total lack of will-power to get this question answered, in my view, […]

Adam Hibberd Around the middle of last year I read an article by Siraj and Loeb in which they analysed closely a database of bolides (which are meteor fireballs) maintained by NASA-JPL CNEOS (Center for Near Earth Object Studies). In so doing they identified at least one bolide as having an interstellar origin (designated CNEOS […]

Adam Hibberd Project Lyra is the study of the feasibility of a spacecraft mission to the first interstellar object to be discovered passing through our Solar System, designated 1I/’Oumuamua. I have now authored and co-authored a total of nine Project Lyra papers. The considerable number of science papers (many now peer-reviewed, several still to be […]

Adam Hibberd In the UK Spring of 2017, I derived the theory for solving interplanetary trajectories, which enabled me to develop a powerful software tool for optimising hight thrust spacecraft missions, a tool which I called Optimum Interplanetary Trajectory Software (OITS). For those of you fascinated by mathematics, in particular mathematical formulae, the two equations […]

It struck me a while ago that I have developed this extremely effective tool for solving interplanetary trajectories (OITS), so how would I be able to exploit it for alternative applications – applications which would be beyond its originally intended purpose, that of designing trajectories for chemically propelled spacecraft (and in the process assuming impulsive […]

Adam Hibberd I was recently discussing with my colleagues across the pond, the potential for mounting a cheap mission to some alternative, yet interesting destination in the inner Solar System, by exploiting a ‘ride-share’ with a more important mission, possibly one organised by NASA or ESA. It struck me that since there have been, and […]

Adam Hibberd An Oort cloud comet is composed primarily of dust and ice and has spent most of its life in the far-flung distant reaches of our Solar System (2,000 au to 200,000 au from our Sun). It is eventually nudged inward towards our Sun by gravitational influences such as galactic tides or some passing […]

Adam Hibberd Following on from my previous blog where I studied the capability of the up-coming Ariane 6 4 launcher in terms of delivering a spacecraft on a course to intercept the first interstellar object to be discovered, ‘Oumuamua, I continue this logical progression with analysis of a more powerful launcher, the Falcon Heavy. The […]

Adam Hibberd Ariane 6 is the up-and-coming successor to the old Arianespace workhorse, Ariane 5, and may secure its maiden flight later this year. There will ultimately be two strap-on booster configurations from which to choose, one with two boosters, and the more powerful version with four. I thought it might be worthwhile assessing the […]

Adam Hibberd If you have a fascination for the mysterious interstellar object ‘Oumuamua and are musically inclined, please check out these two pieces by my musician friend Robin Jax based on recordings of me playing two piano compositions of mine. Whether it be Robin’s neurodivergence, or my own schizophrenia, we have both overcome our respective […]

Adam Hibberd Here is a ‘pork chop plot’ of missions to ‘Oumuamua using a Jupiter powered gravitational assist (or a Jupiter Oberth Manoeuvre, JOM). Refer to the Figure (1). Essentially, what we have are three coordinates where firstly the horizontal axis shows the launch date, the vertical axis shows the flight duration, and for every […]
