Mars this morning....


With both its satellites in the same frame for a change. Notice the polar ice cap, and the 5,000 Km long canyon, or scar, below its equator. Probably a result of its being hit and punctured by a large meteoroid about 3.5 billion years ago. But I've told you that story already, haven't I? I've wondered what it looked like before all that. When it had oceans, and continents, and an atmosphere like ours. Imagine if it had developed like Earth. We might now be communicating with people on another planet, hopefully friendly.

I wonder what we could learn of the universe if we had powerful radio telescopes on both of these planets, coordinated to focus on the same objects?


Imagine a base line this long between observatories? Wow! Standing here on Mars, we can hardly see Earth.... especially not in daylight, as it is right now.
