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)
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
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
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
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
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?
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
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
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 […]
