Cassini Captures Narrow-Angle, Wide-Spectrum Views of Rhea

After spending a couple of years in an orbit riding high over the northern pole of Saturn Cassini has swung back down alongside the planet’s ringplane, in perfect alignment to once again capture views of the icy moons that reside there. The image above is a composite made from several narrow-angle camera images acquired by Cassini on Feb. 9, 2015, showing an extended color view of Rhea as the spacecraft was heading to perform a targeted flyby of the larger haze-covered moon Titan.

Saturn’s second-largest moon, the heavily-cratered Rhea wouldn’t appear this golden to our eyes; its natural colors are much more monochromatic (i.e., grey.) But Cassini can “see” in light stretching from ultraviolet to infrared, and that added range lets us see Rhea in a new light.

In your home on Earth, if something smells bad all you have to do is open the windows to let in some fresh air. But on astronauts’ homes in space – whether it’s the ISS, on board a Soyuz TMA, or, one day, inside the Orion capsule – that luxury isn’t an option. All the air available for breathing must be included in the craft and constantly scrubbed for contaminants and recycled. And if there’s something on board that happens to have an obnoxious odor you’re stuck with it for the duration of the mission… which could have negative side effects on the performance of crew members, if it’s bad enough.

This is why NASA needs George Aldrich. A Chemical Specialist at the White Sands Test Facility in Las Cruces, New Mexico, George works in the Molecular Desorption and Analysis Laboratory and…

PHA PSA: There’s No Need to Worry About Friday’s Asteroid Pass

Lights in the Dark

It happens every time: an asteroid is slated to make a perfectly safe pass by Earth on its route around the Sun, like everyone else, but the tabloid “news” sites take the opportunity to start screaming bloody horror about the upcoming “near miss” and “terrified” NASA scientists etc. etc. It’s awfully tiring and even more predictable than the asteroids’ orbits themselves. I’d usually ignore such things except that they have the unfortunate side effect of actually 1. garnering a lot of attention, at least for a short period of time; and 2. scaring the bejeebers out of people who may not follow real space science news as much as I do. (Which is a lot of people.) So in an attempt to sort out any confusion I’ll say for the record:

There is no need to worry about asteroid 2014 YB35.

What Will We Name the Features on Pluto? You Decide.

This July the New Horizons spacecraft will perform its long-awaited flyby through the Pluto system, capturing unprecedented data and images of the distant icy planet and its companion satellites Charon, Nix, Hydra, Kerberos, and Styx. The first two worlds, in particular, will have their surfaces seen in high-resolution, allowing scientists to observe and map their features for the very first time. But as landforms come into view – craters, mountains, scarps, plains, and who knows what else – what will they be named?

This is where YOU come in.
