Multi-billion-dollar space telescope programs aren’t only feats of aerospace engineering. They also feature “lies, damn lies, and statistics.” Or at least statistics. They definitely feature those, as does all good observational astronomy. The problem with statistics is, in order to get a clear definitive answer, you need lots of samples. And, to put it mildly, […]

New observatories and spacecraft missions are probing environments in our solar system that could potentially host life but have long remained hidden. Icy moons like Saturn’s Enceladus and Jupiter’s Europa likely contain oceans beneath frozen outer shells. But a layer of ice prohibits space probes from sampling them directly.

When it comes to understanding Earth and our changing environment, space is the place. Not only does it give us an overall holistic view of the planet below, but satellite-based imagery can transcend national boundaries and give us an understanding of key changes that often go unseen at ground level.

The “soil” blanketing the moon’s surface isn’t actually soil. It’s a fine, lethal, abrasive powder of shattered rock and jagged glass that shreds gaskets, chews through seals, and hangs in an airless environment blasted by unfiltered radiation and temperature swings that can warp steel. Scientists call it lunar regolith.

There is a chamber at NASA’s Johnson Space Center in Houston that is, in its own way, one of the most extraordinary rooms on Earth. Chamber A is one of the largest thermal vacuum facilities in the world, a vast steel vessel that can recreate the airless, temperature swinging brutality of space without leaving the […]
