    Summary

    This work is dedicated to the late Ben Finney, co-editor of Interstellar Migration and the Human Experience, and co-organizer of the eponymous Conference on Interstellar Migration in May 1983.  The paper was modelled on W.K. Hartman’s "The Resource Base in Our Solar System" (appears as the second chapter), and follows my own "Fusion Fuel Resource Base in Our Solar System", as presented at I4IS's "Foundations of Interstellar Studies" workshop at City University of New York in June 2017, and published in JBIS 71, no.8 in 2018.  It was then presented as "Assuring Humanity's Interstellar Mission Capability for Posterity, or, Learning from Bronze Age Mistakes" to the Society for the Study of Conceptual Issues in Astrobiology in December 2020 (SSoCIA 2020, see https://www.youtube.com/watch?v=STHW4OAsumk&list=PLMo6NPJuxFNma4H1kCOli6GzPwoQ54_LD&index=7 ).

    If a self-propelled ship is going to get to another star in less than many millennia, based on known physics, humanity will need vast quantities of highly energetic fusion fuels.  However, all of the light fusion reactions the human race knows about have major drawbacks.  One cannot be replicated by people yet; due to "the neutron problem," three are better suited for interplanetary travel, not beyond.  Only one, the aneutronic proton+boron-11 reaction, is suitable for interstellar travel.  However, boron is extremely rare in the solar system, and throughout the cosmos.  This limit on fuel supply likewise limits the number and throw-weight of interstellar missions we would be capable of launching over the next millennium.  Like W.K. Hartman, I will bound the value of this constraint, in order to inform the general discussion in this field.  There are lessons from antiquity we can learn from in order to deal with the surprising result.

    Swarming Proxima

    20 November 2023

    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 […]

    Laser and Sail in Earth Orbit with Evolutionary Neurocontrol

    24 October 2023

    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 […]

    OITS Takes on Evolution

    10 September 2023

    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 […]

    How Close did ‘Oumuamua Approach Each of the Inner Planets?

    2 September 2023

    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 […]

    Was Loeb’s Bolide Interstellar?

    1 September 2023

    Adam Hibberd Loeb’s interstellar spherules have caused controversy and indignation amongst experts in the science community. For those of you not-in-the-know, Loeb travelled to the site of a proposed interstellar meteor (his designation: IM1) which he had identified in a catalogue of bolides held by NASA and then discovered in the ocean tiny metallic blobs he […]

    ‘Oumuamua – a Sci-Fi Story or Reality?

    23 August 2023

    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 […]

    ‘Oumuamua: The Mystery Unfolds

    20 August 2023

    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 […]

    Psyche: OITS has Something to Say

    18 August 2023

    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 […]

    Project Lyra: Ignore the outlier and miss an opportunity

    31 July 2023

    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, […]

    The Case of Fireball CNEOS 2017-10-09

    28 July 2023

    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 […]

    Project Lyra: The Mission to Resolve a Mystery

    4 July 2023

    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 […]

    Optimum Interplanetary Trajectory Software: The Secrets Revealed

    25 June 2023

    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 […]

    Laser Sails: Trajectories Using Optimum Interplanetary Trajectory Software

    16 June 2023

    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 […]

    Mars Ride-Share: an Opportunity Not to be Missed

    14 June 2023

    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 […]

    C/2014 UN271 the comet which will NOT collide with the Earth

    4 April 2023

    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 […]

    Project Lyra: Falcon Heavy Expendable

    27 March 2023

    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 […]

    Project Lyra: Using an Ariane 6

    16 March 2023

    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 […]

    Optimum Interplanetary Trajectory Software (OITS)

    15 February 2023

    Adam Hibberd I started development of this software, OITS, in April 2017 on a holiday near the little town of Cheadle, in the county of Staffordshire, UK. I started from the very basics, deriving the theory during the holiday and continuing shortly thereafter, and then immersed myself in the implementation of the equations I had […]

    Music of ‘Oumuamua

    30 January 2023

    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 […]

    Things to Come

    22 January 2023

    Adam Hibberd I sometimes wonder at the short-sightedness of people. The sort of people who scoff and scorn at the far-sighted work which most of my work colleagues and I have dedicated a good deal of our lives to pursue, largely voluntarily. They may argue: We have such and such a problem NOW, how are […]

    Project Lyra: Using Jupiter Alone to get to ‘Oumuamua

    9 January 2023

    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 […]

    ‘Oumuamua: The State of Play

    30 December 2022

    Adam Hibberd In 2017, an interstellar object was discovered, the first ever to be detected. It was observed by the Hawaiian observatory Pan-STARRS, subsequently studied by many telescopes before disappearing into the distance in January 2018. An estimate on the number density, N (how many per unit volume), in interstellar space was determined based on […]

    Why the Stars?

    24 November 2022

    Adam Hibberd November 2022 People may ask the question why we should venture beyond our solar system to explore the stars? Why should we commit precious resources to such an endeavour? I have an answer to this which may to some degree be a personal one. The question boils down to why are we curious? […]

    Exploring ‘Oumuamua’s Trajectory – Further Notes

    9 November 2022

    Adam Hibberd November 2022 In my last blog I reported the progress of my work regarding the intriguing little conundrum of the first interstellar object (ISO) to be discovered, designated ‘Oumuamua, in particular my research into its orbit. In fact ‘Oumuamua is puzzling on many counts and I have also in a previous blog elaborated […]

    Exploring ‘Oumuamua’s Perihelion Date

    31 October 2022

    Adam Hibberd October 2022 This blog may be a bit cheeky but do take heed of the last line before jumping to any conclusions! I’ve been mucking around with ‘Oumuamua’s orbit on my computer lately. Mucking around in the sense of playing with its orbital parameters and seeing what crops up. Those of you who […]
