New Theory: Catastrophe Created Mars' Moons

By Leonard David Senior Space Writer

posted: 07:00 am ET 29 July 2003

PASADENA, California – The two moons of Mars – Phobos and Deimos – could be the byproducts of a breakup of a huge moon that once circled the red planet, according to a new theory. The capture of a large Martian satellite may have taken place during or shortly after the formation of the planet, with Phobos and Deimos now the surviving remnants.

Origin of the two moons presents a longstanding puzzle to which one researcher proposed the new solution at the 6th International Conference on Mars, held here last week. "Nobody has been able to explain the origin of Phobos and Deimos," said S. Fred Singer of the University of Virginia’s Science & Environmental Policy Project in Arlington, Virginia.

Violating laws

Based on research performed as a visiting scientist at the Lunar & Planetary Institute in Houston in October 2002, Singer said that conventional hypotheses about the moons either violate physical laws or have difficulty accounting for their observed orbits

Singer reported at the meeting that "there are no ready alternatives to explain the origin of the Martian moons."

At present, both satellites have near-circular and near-equatorial orbits. Phobos’ orbit, however, has been observed to shrink since its discovery in 1877. The present track of Deimos -- just beyond the synchronous limit where it nearly matches the spin rate of Mars – is an important data point, Singer said. "Is that by accident? I don’t think so…it gives you a clue about its origin," he told SPACE.com.

Through a complex set of orbital calculations involving Mars, the large hypothetical Mars moon itself, and tracing back in time the past and present whereabouts of Phobos and Deimos, Singer believes he has a case. In the Singer scenario, the close proximity of a large original moon to the red planet – captured in Mars synchronous orbit -- would have eventually fractured the object. Gravitational pushes and tugs would have turned it into a rubble pile that would still cling together gravitationally. "Forces would soon drive the largest pieces into Mars, with the smallest pieces remaining as Phobos and Deimos," Singer said. In the breakup process, the most massive pieces would spiral in far more rapidly, crashing into the planet. "We need to look for some sign that these existed."

Phobos: going, going, gone

A fundamental prediction by Singer is that the moons are similar in composition and petrology. However, Phobos and Deimos do not appear to be comparable. That distinction is obvious in looking at the differences in their regoliths – each moon’s topside covering. "We need both surface and deep samples to decide this issue, and to investigate whether Phobos and Deimos once formed as parts of a larger body, most of which has now disappeared, perhaps by impacting on Mars," Singer said.

Singer said Phobos will die in a few million years. "We’re lucky in the sense that we’re seeing Phobos while it’s still around," he said.

Destination Deimos

Singer has plans for Deimos. The scientist believes the moon would serve as a natural space station for future human explorers.

"First of all, humans on the surface of Mars cannot really do the exploration directly. They have to use rovers to get around. To go from the equator to a pole on Mars just takes too long. It’s a big, dangerous journey," Singer said. What Singer envisions is a Deimos gateway to extensive Mars exploration. An encampment of astronauts would reside on the Martian moon. From there, dozens of rovers could be autopiloted, in real-time.

"There would be no time delay, or so short that it’s within the human reaction time," Singer said. From Deimos, quick, down-to-the-surface sorties could be undertaken by humans to select areas, he added.

"This would be a 15-year project, as I look at it. It would cost roughly $30 billion, funded at some $2 billion a year average. That’s well within the existing NASA budget," Singer said. On the political side, Congress is not likely to fund a long series of robotic roving probes to Mars that extends over decades. "That would not be a very efficient way of studying Mars. If you want to solve the really big problems of Mars, like origin of life, you need to do this in one fell swoop," Singer concluded.

Deimos is okay. Phobos is better. The point is that we don't have to land on Mars, but can build our Mars base on one of the moons. Much easier, much safer.

Unfortunately, nobody has been able to explain the origin of any moon in our solar system. Why should Phobos and Deimos be any different?

Almost all books I read as a kid said that Phobos and Deimos were both just captured asteroids, mostly because they looked lumpy and pock-marked like other asteroids.

That's the problem. If they were captured asteroids they should have elliptical orbits. Phobos and Deimos have nearly circular orbits like Earth's Moon.

Circular orbit is tough to acheive in a gravity capture.

Phoebos and Deimos are two asteroid generation ships which took up orbit around Mars sometime prior to 1877. The crews have since been exploring the Solar System and account for all those UFO sightings.

Hey, I can come up with just as plausible a conspiracy theory as anyone else!

I read books as a kid too.

How about this: "They have likewise discovered two lesser stars, or satellites, which resolve around Mars, whereof the innermost is distant from the center of the primary planet exactly three of his diameters, and the outtermost five; the former revolves in the space of ten hours, and the latter in twenty-one and a half; so that the squares of their periodical times are very near in the same proportion with the cubes of their distance from the center of Mars, which evidently shows they to be goverened by the same law of gravitation that influence other heavenly bodies." -A VOYAGE TO LAPUTA, GULLIVERS TRAVELS, 1726

This discription is within 20% accurate, but the moons were not discovered until 1877 when a powerful enough telescope was created. The moons of Mars have the lowest index of reflectivity of any bodies that we know of in the solar system(almost black). They are also so small, that to be seen from earth by the naked eye, Mars would have to appear in the sky 50 times larger than our moon.

Explain that!

What if Mars were a moon of a large planet whose remnants now make up the asteroid belt? The shape of Mars suggest that it was in synchronous orbit of a large object or a large object was in synchronous orbit with it. If Mars was a moon of a large planet and that large planet disentegrated for some reason, the odds of pieces of that planet being stationary relative to Mars may be low enough that there is only two pieces (Phobos and Deimos) left today in circular orbit (interesting that Deimos is in nearly syncronous orbit). The disentagration process may be what pushed Mars to it's orbit now or perhaps the disentgration took place at the right moment in Mars' orbit around the large planet to take Mars to it's current orbit. Mars shows signs of being plastered on one side by debris miles thick, like a person's head in a pie fight. Whatever happened, it happened in one day, not over the course of thousands of years. It seems to me by measuring the nodes on Mars (nodes created by the synchronous orbit), we could estimate the size of the object that was either orbiting Mars or the object Mars was orbiting, whichever the case may be.

That's van Flandern's radical proposal. Nothing adds up, mass, orbits, composition, time schedule. We may never know. If we did know, it would be one of the few things we actually know.

There has to be an explanation of the fact that it is plastered on one side, though. It was close to a planet-size or at least a large-moon-size object that disintegrated. If it weren't for that then this would be a radical theory because there wouldn't be much evidence. I think it's more radical to ignore this plastering than to consider a theory that explains it.

It's not within 20% accurate. The orbital radii of the moons are at 9378 km and 23459, or about 1.4 and 3.5 diameters.

Still, it is remarkable.

A trip back down "memory lane" for y'all...

You're a marine, one of Earth's toughest, hardened in combat and trained for action. Three years ago you assaulted a superior officer for ordering his soldiers to fire upon civilians. He and his body cast were shipped to Pearl Harbor, while you were transferred to Mars, home of the Union Aerospace Corporation. The UAC is a multi-planetary conglomerate with radioactive waste facilities on Mars and its two moons, Phobos and Deimos. With no action for fifty million miles, your day consisted of suckin' dust and watchin' restricted flicks in the rec room.

For the last four years the military, UAC's biggest supplier, has used the remote facilities on Phobos and Deimos to conduct various secret projects, including research on inter-dimensional space travel. So far they have been able to open gateways between Phobos and Deimos, throwing a few gadgets into one and watching them come out the other. Recently however, the Gateways have grown dangerously unstable. Military "volunteers" entering them have either disappeared or been stricken with a strange form of insanity-babbling vulgarities, bludgeoning anything that breathes, and finally suffering and untimely death of full body explosion. Matching heads with torsos to send home to the folks became a full-time job. Latest military reports state that the research is suffering a small set-back, but everything is under control.

A few hours ago, Mars received a garbled message from Phobos. "We require immediate military support. Something fraggin' evil is coming out of the Gateways! Computer systems have gone berserk!" The rest was incoherent. Soon Afterwards, Deimos simply vanished from the sky. Since then, attempts to establish contact with either moon have been unsuccessful. You and your buddies, the only combat troop for fifty million miles were sent up pronto to Phobos. You were ordered to secure the perimeter of the base while the rest of the team went inside. For several hours, your radio picked up the sounds of combat: guns firing, men yelling orders, screams, bones cracking, then finally, silence. Seems your buddies are dead. It's Up To You Things aren't looking too good.

You'll never navigate off the planet on your own. Plus, all the heavy weapons have been taken by the assault team leaving you with only a pistol. If only you could get your hands around a plasma rifle or even a shotgun you could take a few down on your way out. Whatever killed your buddies deserves a couple of pellets in the forehead. Securing your helmet, you exit the landing pod. Hopefully you can find more substantial fire power somewhere within the station. As you walk through the main entrance of the base, you hear animal like growls echoing throughout the distant corridors. They know your here. There's no turning back now.

The most probable theory advanced so far is that Phobos & Deimos are the residual of a catestrophic impact of an asteroid into a pre-existing larger moon.

Let me rephrase that. Topographical studies (or studies of the crust) show that the loose pastered debris is sitting on top of a former surface that is visible on the unplastered side.

It could be that. There is the lower side that is relatively uncratered and the high side that is extensively cratered. Whether the low side is what was left after removal of material, or the high side is material that was added is a question that might be resolved by extensive geological digging. It seems that each successful probe to Mars raises questions but answers little.

When they taught in the 50s the story of where the moon came from, they had diagrams showing the moon material being ripped from one side of the earth's crust presumably where the Pacific Basin is today. Something similar could have happened to Mars, but there is of course nothing left of this material except the two small pieces Phobos and Deimos, if they came from that event and aren't just some kind of captured asteroids. There is no reason to expect that a captured asteroid would settle into a circular orbit except that is what happens apparently around Jupiter and Saturn. What could circularize such orbits when there are only a couple of small moons?

The faster something travels the more speed it loses when it collects space dust, meteors, etc., perhaps. If there was a giant disentegration of a large planet, then all the extra dust and debris in the inner solar system would serve as a drag on any object in an elliptical orbit because objects in an elliptical orbits would have portions of their orbits where they are going faster than the dust and objects their colliding with before gravitational attraction sped up the dust and debris right before impact. It would be more of a drag when the object is going fast and less of a drag or perhaps even a push when the object is going slow in it's various positions of it's elliptical orbit. Over time, that would circularize the orbit, I would think, especially on a relatively small planet like Mars, or on a small moon like Phobos. As the inner solar system has been cleaned up over time, this drag is less apparent now but it could've been a lot greater right after the event. Maybe Mars hasn't collected enough debris and dust to circularize it's orbit, I don't know. From what I understand Mars orbit isn't all that stable. It could mean it hasn't been where it's at for very long.

It seems that where there are several bodies, moons or planets with some mass and gravity in orbit around a primary, they tend to affect each other's orbits in such a way as to circularize all of them. It might be that one of them is left wildly elliptical and that one gathers up energy and gets flung completely out of the system or sent into the primary itself leaving the rest with quieter orbits. Just like people, older neighborhoods tend to be quieter.

Are you kidding me? You'd have to have 'nads to try a stunt like that. Those guys usually took a giant-size chunk outta my face before I could fire up the 'saw. I'd rather shove both barrels of my shotgun into its mouth and pull the trigger. Or whip out the plasma rifle and liquify its eyeball.

I've uttered more naughty words than I can count stalking those things late at night. Of course, nothing beat the feeling of hearing the blood-curdling roar of a Pinkie behind you, whipping around, then blowing him away.

There is one way to make a moon in a circular orbit that I have never seen mentioned in the astrophysics books. You could call it "Roche lifting". Whenever two massive bodies pass within the Roche limit (about 3 radii) of one another, the more massive one will tidally disrupt the less massive body.

The same effect that causes comets to break up as they pass Jupiter could lift the crust from a planet to form a moon, without a direct impact between the two bodies.

Of course, if the bodies pass too close, the less massive one becomes an asteroid belt.

Sounds so serene and decorous. Lift the crust. That's the model they taught, and it seems to be popular again. Some large body came by earth way back when and pulled the material out into space where it recollected forming the moon. It would probably work for Mars, too, even though Mars seems to have totally lost most of its material from one side of the planet anyway, not even a good-sized moon left. If Mars had a moon formed that way, it seems to be long gone, who knows where; it ought to be in a similar orbit as Mars, but there is nothing there. Perhaps Mars was farther out when that happened and has migrated inward toward the sun leaving the debris in the asteroid belt. Perhaps we'll track it down when we have done enough geological prospecting in the asteroid belt and have some good data.

Yeah, you're right. I don't think we understand much about about the rotation and orbits of planets. Just looking at the earth science says that our magnetic field is created by the iron core spinning faster than the mantle. If so why does magnetic North wander so unevenly around. There appears to be more than just momentum, angular momentum, and mass involved on the orbits and rotation of planets. It could be that our planet rotates in equilibrium. Maybe the electromagnetism from the sun rotatates our core so that it's force versus the friction of the oceans and the liquid parts of the mantle create a 24 hour day, unable to speed up because of the friction of the liquids mentioned, and unable to slow down because of the electromagnetism of our core and/or the sun. Then there's the spiralness of galaxies and Saturn's rings. Doesn't make sense if there is just gravitation and momentum involved. Just too many inconsistencies for me to accept mainstream sciences explanations for the movement of plantary bodies. I spent the last day looking into some theories but it's just too broadbased to try to make a point on. :^)

The celestial mechanics problems that have been completely solved are very limited and don't represent the system as a whole. Lately computer modelling is giving some pictures of entire systems of good complexity. They throw in everything they can think of, but are they getting all the parameters?. It's similar to the problem of trying to model earth's and other planets' and stars' climates. You can get some results and maybe some inspiration, but really the technology of computer modelling is just in its infancy. How do planetary orbits circularize? Where do galactic spiral arms come from and how do they move? I don't know if there is an employed, working scientist who will say it is definitely this or that. We don't even know if spiral arms move clockwise or CCW. We don't even know they aren't a total artifact of stellar evolution rather than orbital mechanics. Of course, we haven't left our front porch yet, either, so we can't be expected to actually know anything.

Some large body came by earth way back when and pulled the material out into space where it recollected forming the moon.

Since the iron core model of the earth doesn't work for me (because of the jaggedly wandering poles), I have my thoughts on the movement of continents and the Pacific Basin also. The nature of our magnetic field with it's flips, etc., resembles more a nuclear core than just an iron core. If only 1 percent of the magnetic strength is able to get through the mantle of the earth, then there may be some other physics going on. Perhaps a Meissner effect that could have spread the continents apart.

(Just a word to the scientifically wise because this has implications that I don't want to get into publically...and that's all I have to say about that...:^)...)

Yeah, we know enough to get Voyager to go past Neptune, but that may be the basics. Do rotating bodies affect time and space around them differently than non-rotating bodies? I think studies of our satellites a few years ago proved that earth's rotation did have some kind of effect on space that Einstein predicted.

One way to find out what's down there. Core sample. A REAL Core sample from the Core. I am still entertaining the possibility that the atmosphere of earth is responsible for the earth's magnetic field. Earth's core may be iron, but it needn't be magnetized, and even though rotating needn't generate a mag field by any means including cutting flux lines emanating from the sun or Jupiter.

Could be something to consider.
