Adam Hibberd Having demonstrated yesterday that a reasonably low DeltaV (velocity increment) applied by the Juno’s engine could achieve a significantly closer approach to 3I/ATLAS than would otherwise be the case if Juno stayed in its current Jupiter orbit, surely that would be the end of the matter? The answer is ‘not quite’, since this […]

In this case the question goes like this: ‘is 3I/ATLAS, the third interstellar interloper […]
Missions to 3I/ATLAS
Adam Hibberd The third interstellar object is causing a bit of a stir. What could it be exactly? Judging by its predicted path, we should get a ring-side view of it from Earth, except for an important viewing outage as it approaches perihelion – the closest approach to the Sun – simply because it will […]
