Mars Moons

ars Moons  (Read 203 times {at the thread top

ad 198 i think moon returns to Earth & < 1e9 (B}?

ission costs $671 million. /  "We don't have that answer yet
_
My guess is about as follows, Phobos is a chunk out
of the side of Mars | Just as Earths Moon | there should be a scar
| Just as there is the Pacific Basin So Lemmee Look
.1 how big is the Moon | The moon is about one-fourth as big as Earth
a? 1/80th of Earth's mass and 1/ 50th of Earth's volume
  b~ volume contains 2.195 x 10^10 km3
2: Pacific Basin | volume of the Pacific Ocean
  a? estimated at some 714 million cubic kilometers.  thats an 8
   b~~ i do assume that due to continental drift, double 7
     c? hmm? My guess is Moon does contain its creator ? at the core
4: Mars's P Mean Radius: 11.1 km. Volume: 5,729 km3. Pretty tiny e=3
   a i can find my best guess using "crater" basic / from win 98 |tbd}

Both Phobos and Deimos are probably captured asteroids. We do know that Phobos will eventually collide with Mars. Likewise we know that Deimos will eventually drift from Martian orbit.

It is almost certain that Luna (to specify Earth's moon) was formed from an impact with proto-Earth and a Mars sized body, which eventually sank in and became the Earth's interior, at an oblique angle. Actually, Luna is probably unique in the solar system in that it is not either a captured satellite nor a body that coalesced in the same orbit, Luna is the direct offspring of its parent planet. Luna, incidentally, would eventually fling off from Earth orbit, but the Sun's death will put an end to that process well before it comes to be.

ad 198 that said i came away from BASIC with a new idea
it was not an impactor {however its spelled | it was a volcanic eruption.

I don't know what ad 198 means.

It is however proven that the Moon is moving away from the Earth an average on one inch per year. Data has been collected since the first human landing on this.

Warning - while you were typing 2 new replies ha

Hirley, you might be interested to know that I was going to pick your brain about the discrepancy between Venus' mass and Earth's mass and comparing the density of their atmospheres. Turns out that Earth's atmosphere was thinned by carbon dioxide sequestering because of liquid water. Nitrogen obviously came through other processes and the oxygen came about through photosynthesis, thus making atmospheric oxygen more or less a smoking gun in the search for extraterrestrial life, since, well, oxygen is a highly volatile gas.

ad 198 that is fine by me /-/owever Mine has been so badly
damaged in the fray that i do NOT trust it in any way whatsoever
it continues to com up with the rong dog. Anyway Looking }
oxygen  (yeah as in H2O water
carbon dioxide CO2 ? why is the number a suffix????/ & not A preMe
Nitrogen yeah? as in Laughing gas is my guess
it seams to methat U r leaving out Argon

You are right, but argon was virtually non existent in the original atmosphere, and is negligible in the current (though IIRC, third most abundant)

[Nephew Twiddleton]

That does bring up another interesting thing though. Nitrogen, while unbreathable in the sense that our lungs don't use it, is necessary to make air breathable, and it's not exactly an abundant gas elsewhere. What do you think about getting about 78% N₂ gas locally when we get to the colonization business?

[Nephew Twiddleton]

Krackatoe

That would also be one hell of an eruption too.

I'd like to see what you have on that.

Krakatoa didn't produce a lunar mass object, though.

well space monkey what can a water monkey say ?

It is however proven that the Moon is moving away from the Earth an average on one inch per year. Data has been collected since the first human landing on this.

yes: i agree it currently is doing exactly that / more slowly each Ms
eventually, as Moon & Earth gain mass, it slows to " 0 "
& then it turns tail.

How would either gain sufficient mass to reverse the process?

Hmm. I would have to think about how much mass either has gained through impacts over the past 4 some odd billion, and see where the trend is going.

well i sort of doubt this.
i'LL guess there is a chance that the hollow in Phobos
has an atmosphere May need filtering? { a new r {{yeah yeah {{{U's win

[hirley0]

My Reference was reguarding Energy{not to sure about Mass

i will check later{it takes a lot of time to switch XP->W98

12:21 the next day ad 234 A <20Km sphere Think Tualatin valley
A caldera 80 km (50 mi) wide is located at the summit of Olympus Mons
YES of course i will stick to Mons as "FROM WHENCE" it came
its reel easy 4Me to put the frames toGETher
.1 phobos is launched / with sufficient V to approach Orb
a. rising rather slowly / due to mass
2: a second more violent eruption = hi speed boster
  b. when Booster hits phobos | hard enough
   c: to cause phobos to loose its guts @->(_)=<
3? leaving a hollowed out P { Probably | gO Mons

Muy guess was in 4.5 Earth about doubled in mass
as for the Moon | i have no guesses | yet | only that | More arives than Leaves

That possibility did occur to me as far as the discrepancy in density goes. It would have to be a very light atmosphere though, no? Otherwise the mass would be noticeable?

This is true. I suspect it's an overestimation, but I have nothing to base that on other than knowing that Heavy Bombardment would have to have ended before life could thrive and evolve.

[hirley0]

Nitrogen,

That possibility did occur to me

space ? water  ? yes: i agree

This is  I suspect

This is the sort of thing that makes my eyes cross, and part of where I don't understand you. What am I looking at here? (Thank you, btw, whatever it is)
