There was a press briefing today to announce that Curiosity has completed her last major first-time activity: powder drilled from inside a rock at John Klein successfully made its way into the CHIMRA sample handling mechanism in the turret. Sol 193, then, marks the day that Curiosity is finally ready to start the science mission.
Imagine you had a Hubble-class telescope and could use in any way you wanted to explore planets. What would you do with it?
A frequently-asked question last week was: if asteroid 2012 DA14 is coming so close to Earth, why hasn't anyone taken any pictures of it? Now that 2012 DA14 has whizzed past us, we do finally have some radar pictures of it, but they still may not satisfy everyone.
Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14. I work for Las Cumbres Observatory and we have been trying to observe this asteroid since 5 February.
Last week, I posted an explainer on why Hubble's images of galaxies show so much more detail than its images of Pluto. Then I set you all a homework problem: when will New Horizons be able to see Pluto better than Hubble does? Here's the answer.
