Rosetta NAVCAM's Shades of Grey

What do “light” and “dark” mean for an object like Comet 67P/C-G? Here are some details on how Rosetta's NAVCAM images are taken and displayed to make a wide range of surface features possible.

Using Lasers to Lock Down Exoplanet Hunting

The Planetary Society is launching a new collaboration with Yale exoplanet hunter Debra Fischer and her team, the Exoplanets Laser project. We will support the purchase of an advanced, ultra stable laser to be used in a complex system they are designing to push radial velocity exoplanet hunting to a whole whole new level.

There are swirly indications from a study of how to optimize the lander pad portion of the Planetary Society/Honeybee Robotics PlanetVac planetary surface sampling system.

PlanetVac at the IEEE Aerospace Conference

PlanetVac project leader Kris Zacny of Honeybee Robotics reports on presenting results of the Planetary Society project PlanetVac that created a prototype planetary dirt sampling system and tested it under Martian pressures.

Hypervelocity Cratering and Riding Out the Risk

Today's update from the Mars Express team contains the realisation that, for some of the risks associated with October's Siding Spring flyby, there may not be much the team can do.

Space is really, really big – except sometimes it isn’t

Here's the next installment in the continuing story of how the Mars Express team is preparing for Comet Siding Spring flyby, 19 October 2014. This week: introducing the spacecraft's subsystems and structure – and wondering how we can absorb impacts.
