They would be able to see it - without a shadow of a doubt - IF it's the same shape and size as seen from Mars as it is from Earth. It's not THAT much closer when at Mars - much of the distance from Earth to the Holmes is the out-of-ecliptic distance - perhaps it's 1/3rd closer. But even at the Earth range, it would be easily visible in Navcam as a bright star, and possibly even resolved as a tiny fuzzy dot in Pancam.
However - we are far from the heady days of >850 Whrs when we did astronomy from atop Husband Hill - so it'd be quite an 'ask' in terms of power etc. As for other spacecraft observing it - they could do - not sure if they'd want to go the effort involved though. Doug |
