Posted on 07/03/2022 3:49:50 PM PDT by MtnClimber
Explanation: This moon is doomed. Mars, the red planet named for the Roman god of war, has two tiny moons, Phobos and Deimos, whose names are derived from the Greek for Fear and Panic. These martian moons may well be captured asteroids originating in the main asteroid belt between Mars and Jupiter or perhaps from even more distant reaches of our Solar System. The larger moon, Phobos, is indeed seen to be a cratered, asteroid-like object in this stunning color image from the robotic Mars Reconnaissance Orbiter, with objects as small as 10 meters visible. But Phobos orbits so close to Mars - about 5,800 kilometers above the surface compared to 400,000 kilometers for our Moon - that gravitational tidal forces are dragging it down. In perhaps 50 million years, Phobos is expected to disintegrate into a ring of debris.

Looks like Joe’s head.
Looks like a potato with acne scars.
“In perhaps 50 million years”
I’ll wait ... maybe
Buy-Dung as a teenager. :-)
Phobos suffers yet another cosmic insult.
Ah, yes, but the Phobosians have other plans.
One scientist suggested that the moons were made by intelligent Martians to escape when their seas dried up and their atmosphere changed. They are hollow and the Martians live in them. Over the centuries they have been bombarded by meteorites. That destruction of the Phobos probe is seen as proof they do not wish to be discovered by Hu-mons.
I propose that NASA endow a multi-billion dollar research fund to figure out how to save Phobos. I am available to administer the research fund.
Probably the worst golf ball ever made.

FRANK FRAZETTA!!!...OR A DISCIPLE. GREAT STUFF!
GD stupid people at NASA... If theyre not making fake pictures, they are sensationalizing maybes 50 million years out. I dont know why it still let these fkn APOD threads chap my ass instead of totally writing them off. smmfh...
I’m just saying....
I did the math calculations a long long time ago but I figured that on Phobos the Martian planet will take up half the sky from horizon to horizon. That may be a little scary for an astronaut standing on Phobos.
50 million years?
I’m going to set my DVR right now to catch the epic moment! ;-)
👍 all that cgi in the NASA Photo Gallery and livecasts from the dune buggy scurrying about the Mars terrain, and still not one single shot of the Big Blue Marble/Pear hurling through the Void 🤣
