Halley Rendezvous – the problem of how to get to the comet and stay there.

10 September 2026

Adam Hibberd A rendezvous mission to Halley’s comet? The return visit of Halley to the inner solar system won’t be until around 2061, with perihelion on July 28 of that year.

How long does it take to get to the Sun/Earth L4 Point from Earth?

18 August 2026

Adam Hibberd Let’s say we eject a spacecraft with a small velocity decrement in the opposite direction to Earth’s own velocity around the Sun, what will happen to it exactly? It will stay around Earth’s heliocentric orbit since its velocity is close to Earth’s, however we shall assume that the spacecraft flies outside of Earth’s […]

What is 1998 KY26?

6 August 2026

Adam Hibberd I was recently referred to a paper by Farnocchia et al which apparently, so was it argued, contradicted the notion that 1998 KY26 could be technogenic (man made), in other words a spacecraft. For the uninitiated, 1998 KY26 has always been considered (up-to-recently at least) a Near Earth Asteroid (NEA) of some form […]
