Just in time for the #MMX launch, I've listed these grand statement necklaces that I made from agate or jasper Mars-like beads strung with graduated garnets. A U-shaped pendant holds garnet chunks symbolizing Phobos and Deimos. No two are alike. www.etsy.com/listing/4598...

There are two signed copies of Time’s Second Arrow at my childhood bookstore, Kepler’s Books in Menlo Park, CA!

That's four covers of Science magazine for this incredible team. And we're not done yet.

I have not one, but TWO features in the latest issue of Scientific American, including the cover! First, satellites are being added to the sky faster than ever. But is there a limit, a carrying capacity, to how many can orbit – and is disaster inevitable? www.scientificamerican.com/article/how-...

If millions of satellites launch to space, is chaos the inevitable outcome?

SpaceX and other companies want to put millions of satellites into space. Could orbit run out of room?

The Chinese Tianwen-2 spacecraft did NOT arrive at the small, fast-spinning asteroid Kamoʻoalewa on 7 June - the burn performed that day has not been explained. It will arrive on 4 July. Anyway, here's another more or less relevant post from my blog. spaceflighthistory.blogspot.com/2015/08/expl...
