Mars:

* Evidence of Water: Yes, there is strong evidence of water on Mars, both in the past and present.

* Past Water: There are dried-up riverbeds, canyons, and mineral deposits that indicate Mars once had vast amounts of liquid water on its surface.

* Present Water:

* Ice Caps: The polar ice caps contain vast amounts of frozen water.

* Subsurface Ice: Evidence suggests that there's significant amounts of water ice beneath the surface.

* Atmospheric Water Vapor: Small amounts of water vapor exist in the thin Martian atmosphere.

* Liquid Water: While not permanent lakes or rivers, there's evidence of temporary liquid water flow on the surface, possibly from seasonal melting of subsurface ice.

* Tests that Show Water:

* Orbiters: Instruments like the Mars Reconnaissance Orbiter (MRO) have detected water ice and evidence of past water features.

* Landers: Landers like Phoenix and Curiosity have directly analyzed Martian soil and found evidence of water.

* Rovers: Rovers like Curiosity and Perseverance have found signs of water in the past and present.

Moon:

* Evidence of Water: There is evidence of water on the Moon, but it's in very small amounts and in different forms.

* Ice in permanently shadowed craters: The Moon's polar regions have permanently shadowed craters where ice is thought to exist.

* Water molecules bound to lunar soil: Instruments have detected water molecules bound to the lunar soil.

* Traces of water vapor in the thin lunar atmosphere: Extremely small amounts of water vapor have been detected in the lunar atmosphere.

* Tests that Show Water:

* Orbiters: The Lunar Reconnaissance Orbiter (LRO) has provided strong evidence for ice in permanently shadowed craters.

* Impact Probes: Impacts by spacecraft have released small amounts of water vapor, confirming its presence.

* Landers: Missions like the LCROSS impactor experiment have analyzed the ejecta from a crater, confirming the presence of water ice.

Important Note: The water found on Mars and the Moon is not in the form of oceans or lakes like on Earth. It's mostly in the form of ice or water molecules bound to minerals. The existence of these small amounts of water is still a significant discovery for our understanding of these celestial bodies and their potential for past or future life.
