Re: oceanic tides on mars? - Would Phobos and Deimos have any effect?

Will Mars have tides in it's future oceans influenced by Phobos and Deimos?  Or just the Sun?  Solar tides would be weaker due to distance, and since Mars' two moons are but a speck of dust compared to Luna, they'll have little effect.  However, they are much closer to the planet than Luna is to Earth.  Do you think there will be noticeable ocean tides?

Neither Phobos or Deimos would not have any significant tidal effect on Mars. They just don't have the mass or the gravity to have any significant effect on Mars even being closer to Mars.

You would have to have a Moon orbiting Mars that was several hundreds miles in diameter to have any significant tidal effect on Mars.

So what Asteriod could we nudge out of its space location into mars orbit?

Also would we in turn wake up mars core in doing so?

We could always build a moon. The Big red round one we will probably want to keep but build a frame around the small one and pulverize it and any other asteroid we can get our hands on. A Small factory designed to separate out the metals and spin a sphere of Silicates and eject it into the space inside the framework. It would be like marbles in a bird cage. After the Cage was filled, build a new layer anchored to the old one.

One day it might even be the most noticable object in the solarsystem. All that silicon absorbing solar radiation. It will probably glow like an infrared light bulb.

No noticeable effect from Phobos and Deimos. But yes a moon could be constructed, in way not like the moons of all sub-giant bodies ( after impact) , but in the way of guided artificial accretion of some solid waste material or via moving some of the planemo 4 "asteroids" into Martian orbit.

Mars feels now onlt solar tidal effect.

The tidal effects are proportional to the inverse cube of the distance and the mass of the orbiting bodies. 1 Ceres is about 70 times less massive than Luna. Puting it in orbit at least as close as 75 000 km above Mars will give you the same level of tidal activity as the earth`s one. In martian case Ceres closer than 200 000 km to Mars overwhlms the tidal action of the Sun on the planet ( 7-8 times lower than the solar tides on Earth)...

How to move a planetary mass object as Ceres to Mars:

2. http://www.paulbirch.net/MoveAPlanet.zi … Planet.zip

3. Use a SRA or von Neuman system to gather and crumple in a moon more dispersed material. The Main belt bunch of asteroids is not enough asside the Big Four. Using too small asteroid for martian moon hits the Roche limit`s barrier of 1.44 planetary radii or means too small tidal effect.

Note: silicates are dirt. Our moon is made of this poor material. No metal except the dull aluminium, titan and iron, no volatiles. But the plain alumina ( Al2O3 ) and silica ( SiO2 ) are indeed perfect materials ( quartz, saphire and other cristalic forms in fiber form). They possess alotropic states in form of precious stones, with enormous tensile strenghts - you can build rotating colony of HUNDREDS of kilometers dimater out of alumina and silica. They are cheap and abundant. The dirt of the inner system is not something to be collected in kind of wastepile, but usefull building material. It may occur that in long run the lunar material to be too expenive to be used for moons.
