does mars always have life on earth that is simialr to kepler and anyone else any other planet that has a sateilite?

This question is word salad. It doesn't make sense, either in part or in the whole. I hope this is just an English-as-a-second-language issue.

.

<Does [Mars] always have life> No life has been discovered anywhere other than Earth, including Mars.

.

<Does [Mars] always have life on [Earth]> That makes no sense. If you mean *as* on Earth, the answer is again 'no'.

.

<that is [similar] to [Kepler]> And neither does that. Kepler was a 17th century scientist, or a space telescope, and neither makes sense here.

.

<and anyone else any other planet that has a [satellite]?> Most planets have satellites. Only Mercury and Venus lack them, as does the dwarf planet Ceres. All other planets, including Mars and the dwarf planet Pluto, have moons, though Mars' moons are probably captured asteroids and not naturally-formed moons.

.

The only thing I can imagine you're asking is whether having a moon such as Earth does is a prerequisite for complex life--if the stability the Moon confers on Earth is necessary for abiogenesis (life to begin) and for evolution to occur over the vast spans of time necessary for large multicellular organisms like mammals to evolve. If so, then that's a question I don't think anyone can answer. If there is life on a world like Europa, with a global ocean such that the axial tilt and seasons wouldn't have much of an impact, then it probably wouldn't matter. Could life have formed the way we know it without the Moon? Who can say? Could it form at all? Ditto.

.

If that's not what you're asking, you need to clarify your question a bit, and correct the spelling and grammatical errors as best you can before hitting the Submit button, because you're pretty much unintelligible now.

Mars has no life. It is too cold (minus 100 C) and a near vacuum for an atmosphere.

Mars has two tiny moons (satellites) Phobos (about 22 km (14 mi) in diameter) and Deimos (about 12 km (7.5 mi) in diameter), These are way too small to have any life.

Kepler is a satellite that is looking for planets of other stars. It has found some, but no likelihood that any have life.

Mars has satellites different than Newton but not with life on 3 of them with planets. So, no.
