Is the ISS vibile from Mars?

The bluddy question is stuck in anthropology and YA won't let me move it to astronomy. Apologies for that.

I just asked the question for a bit of fun, but fighting YA to get anything done makes it not!

Finally. In astronomy. And yes I meant to say "Is the ISS visible from Mars". Meaning through a telescope. For argument sake lets say up to an aperture of about 20 inches. It;s been so hard to do this "fun" question, it would have been easier to do the calculation myself!

Without doing actual calculations, it is easy to answer with a resounding no. It might be bright from Earth, 250 miles altitude, reflecting the Sunlight against a dark sky, but even the observing conditions are such that it would not be visible from Mars- even if it were much much brighter.

PS: I do mean with very powerful telescopes.

Probably not.
Not without extreme resolution.

Two answers.... First, it would be lost in 'Earth shine', as Earth's reflected light from the sun would drown out any hope of seeing it - even in a fairly powerful telescope.
Second... YES - if Earth were to suddenly disappear - it *could* be visible, but you'd still need a telescope - with it's very reflective surfaces and solar panels, it would be a bright speck in a telescope (that would need to have 500x magnification or more...)

No. The ISS is only about the size of a football field, and orbits the much MUCH larger and brighter Earth.
