Adam Hibberd This is how I’d explain my paper to a mate in a pub: “The Solar System is comprised of lots of different objects (like planets, asteroids and comets) which go around the central Sun, in huge ellipses. You may say the Earth’s path is circular, that’s true, but in fact all circles are […]
Starship Blog
With the recent creation of the new i4is website, along with the newer blogs, we have included a selection of previous Starship Blog posts from our archive which we hope you will enjoy browsing. If you would like to write an article and have it appear on our web site, then get in touch with us.
Sample Return Mission Feasibility of 2024 YR4
Adam Hibberd A mission to Near Earth Asteroid designated 2024 YR4 which for a while had a relatively high chance of colliding with the Earth. This probability has dropped to zero but instead the likelihood of impact with the Moon has gone up – it is now ~ 4 %. Such a collision would cause […]
A Challenge for OITS
Adam Hibberd I was recently asked by a US colleague to do a little research using ‘OITS’. For those of you unaware by now, ‘OITS’ stands for ‘Optimum Interplanetary Trajectory Software’ and is a powerful tool I developed single-handedly for studying the problem of sending spacecraft on heliocentric trajectories to a planet or for that […]
3I/ATLAS: Is It Worth a Solar Oberth?
Adam Hibberd Have you noticed, 3I/ATLAS is well and truly on its way out of the Solar System? It has afterall passed through its closest approach to the Sun (perihelion) and is well on its way to a close encounter with Jupiter in mid-March – given this, it would seem to be the ideal moment […]
The SpaceX Starship and Catching an Interstellar Object
Adam Hibberd On the request of a colleague, I have solved the problem of exploiting the powerful SpaceX Starship (in fact the yet to be launched Block 3 variant) to lift a spacecraft so that it can catch up with 1I/’Oumuamua, the now rapidly receding ‘interstellar object’. This object sped through the inner group of […]
Principium 51
Principium 51 has gone out to subscribers and is now accessible to all.
3I/ATLAS in Plane Language.
Adam Hibberd I have had many queries concerning the calculation of the likelihood of 3I/ATLAS’s orbital plane lying within 5° of that of the ecliptic of the Solar System. This calculation appears in the paper ‘Is the Interstellar Object 3I/ATLAS Alien Technology?’ which can be found here. The calculation exploits a simple equation based on […]
Elon’s Starship to Launch Project Lyra?
Adam Hibberd Yesterday I was trying to gauge the measure of the SpaceX Starship in terms of its ability to launch the Project Lyra spacecraft on its way to its destination. BTW Project Lyra is the initiative to send a mission to catch-up with very quickly receding interstellar object 1I/’Oumuamua. So exactly how do we […]
3I/ATLAS Mission to Launch in 2035
Adam Hibberd As a consequence of exploring the Solar Oberth option to catch up with 3I/ATLAS, using my software development Optimum Interplanetary Trajectory Software (OITS), I have discovered that a mission exists IN THE FUTURE, with a launch in 10 years time, i.e. in 2035. The video animation can be found on my YouTube channel […]
On a Second Moon and the Zond 1 Probe.
Adam Hibberd 2025 PN7, the widely touted newly discovered quasi-satellite of the Earth, has stirred-up in me a renewed fascination for identifying apparently natural objects as old derelict interplanetary missions. So is this object natural or technogenic? If I were to say 50:50 this could be the failed Russian Zond 1 probe to Venus, what […]
3I/ATLAS: How low should we go?
Adam Hibberd 3I/ATLAS, the interstellar object, is in the Solar System and making its presence known, not only to astronomers but also to the world’s media. My paper with Avi Loeb and Adam Crowl examined the hypothesis that 3I/ATLAS might be alien technology, go here. I confess this paper has been somewhat of a hit! […]
3I/ATLAS: An Interstellar Controversy
Adam Hibberd When you have a surprise, uninvited visitor gatecrash your party, you are liable to treat them cautiously at first and then after a visual appraisal reveals they are worthy of acceptance, maybe curiosity will strike and you may start asking questions to find out more about them. You may by the end of […]
