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 […]

I4is Science Fiction Book Club – Next meeting 10th August I4is recently started this science fiction book club for readers and writers. Due to the worldwide nature of the i4is membership, this book club will be held once a month on Zoom. For the next meeting, the i4is SF Book Club members are considering again […]
Project Lyra: The Mission to Resolve a Mystery
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 […]

i4is Science Fiction Book Club – Next meeting 13th July I4is has recently started this science fiction book club for readers and writers. We read and discuss stories that take the eyes above and beyond the horizon, tales that inspire minds and hearts to leap from here and now to tomorrow and elsewhere. We examine […]
Optimum Interplanetary Trajectory Software: The Secrets Revealed
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
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
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 […]

New i4is Search Facility Using the alert database access kindly provided by our friends at the Interstellar Research Group (irg.space) we have created an enhanced search facility that searches all database fields as you type. We will be adding features to this search in the near future, including filtering by category. The database can be […]
