The Japanese robotic spacecraft Hayabusa2 has arrived at the asteroid Ryugu. Among other things, it’s meant to “use small explosives to blast a crater on the surface and collect the resulting debris”.

NASA’s Jet Propulsion Laboratory has some great free software available that lets you see many solar system bodies (from the sun to Jupiter’s absurd abundance of tiny moons) as well as a wide variety of space missions. Some interesting objects: Miranda, Phobos, Deimos, Io, Europa

Then they led him out again, trying to get him near a mockup of a Mercury capsule, where the television networks had set up cameras and tremendous lights. The reporters and photographers surged forward again, yammering, yelling, exploding more camera lights, shoving, groaning, cursing—the usual yahoo sprawl, in short—and the animal came unglued again, ready […]

After a 20-year mission, and to avoid any risk of contaminating Saturnian moons with microorganisms from Earth, the Cassini space probe was deliberately crashed into Saturn’s atmosphere today. The science it has returned has been stimulating and the imagery spectacular. The watery moon Enceladus now joins Europa among the solar system’s most intriguing life-compatible bodies.

A surprising oversight in Timothy Mitchell’s generally-insightful Carbon Democracy: Political Power in the Age of Oil is how he gives relatively little consideration to static versus mobile forms of fossil fuel consumption. He strongly emphasizes the production and transportation logistics of coal versus oil, but gives little consideration to special needs for fuels with high […]
