Errors in Velocity Due to an Interstellar Probe’s Fast Encounter with a Star
Adam Hibberd A spacecraft is travelling on a very hyperbolic orbit w.r.t. an object X (possibly a star) which has gravitational mass, μ, meaning the spacecraft is only slightly deflected from its direction of motion. Our task is to quantify the errors in velocity, both longitudinal and transverse, associated with this encounter compared to simply […]
Special Announcement: First European Interstellar Symposium – Extended Deadline Call for Papers
The University of Luxembourg’s First European Interstellar Symposium will take place in December 2024, with the IRG’s input and guidance. The Symposium, a Shark Tank competition, and an Interstellar Art Show will be held at the European Convention Center in Luxembourg City, Luxembourg. The symposium will feature many of the leading voices in space exploration, […]

‘Oumuamua: Lasers in Space
Adam Hibberd In my latest research, I have been considering the case of using laser structures in space to accelerate space laser sails to sufficient speed so that they will ultimately reach the first discovered interstellar object, 1I/’Oumuamua, within a matter of years from launch, or even as soon as a year. This is clearly […]
i4is – BBC Sky at Night Feature
Great to see that our research has been featured in the well-known BBC Sky at Night Magazine: “Spacecraft powered by light sails and lasers offer a quicker way to explore the Solar System. But there’s a catch.” Check it out here! Congrats to Manasvi Lingam, Adam Hibberd, and Andreas Hein! (Image credit: BBC)
