Over the Hills and through the Sand: Six Years of Driving on Mars

Over the Hills and through the Sand: Six Years of Driving on Mars

John Wright I almost didn’t get to drive the rovers. As one of the five developers of the software used to build the command sequences and rehearse and visualize the rover activities, I really wanted to be one of the people using it in flight. Unfortunately, only three members of the team were selected to [...]

2012 – A Scientific Reality Check

Donald Yeomans There apparently is a great deal of interest in celestial bodies, and their locations and trajectories at the end of the calendar year 2012. Now, I for one love a good book or movie as much as the next guy. But the stuff flying around through cyberspace, TV and the movies is not [...]

Cassini’s Swoop over Enceladus: First Morsels of Science Coming Back Now

Cassini’s Swoop over Enceladus: First Morsels of Science Coming Back Now

Bonnie J. Buratti Phew! We made it through the deepest swoop yet down into the plume of Enceladus, the encounter we call “E7″ because it’s the seventh targeted flyby of Enceladus. But now we have our work cut out for the next few weeks as we pore over the data, painstakingly analyzing every signal to [...]

Taking the Plunge: Cassini Soars by Enceladus

Taking the Plunge: Cassini Soars by Enceladus

Bonnie J. Buratti After so many close flybys of Enceladus, we’re starting to feel as if this little moon of Saturn is an old friend. But during the encounter planned for Nov. 2, 2009, we are going to get up-close and personal. Cassini is going to take its deepest dive yet into the plumes spewing [...]

Tackling Clouds for Improved Predictions of Future Climate

Tackling Clouds for Improved Predictions of Future Climate

Hui Su Clouds are among the most fascinating natural phenomena and have inspired countless works of literature and art. Their ever-changing forms make them a great challenge to atmospheric scientists working to predict how our climate will change in the future in response to increasing greenhouse gases such as carbon dioxide. Clouds occur at many [...]

Planck Snaps its First Images of Ancient Cosmic Light

The Planck mission has captured its first rough images of the sky, demonstrating the observatory is working and ready to measure light from the dawn of time. Read the Full Story at JPL Blog

Comets and Life On Earth

Comets and Life On Earth

Donald Yeomans With the recent discovery of the amino acid glycine in the comet dust samples returned to Earth by the Stardust spacecraft, it is becoming a bit more clear how life may have originated on Earth. Water is a well-known ingredient in both comets and living organisms, and now it appears that amino acids [...]

Five Things About Viewing Mars in August

Five Things About Viewing Mars in August

Jane Houston Jones If you’re like me, you may have received an e-mail this summer telling you go outside on August 27 and look up in the sky. The e-mail, most likely forwarded to you by a friend or relative, promises that Mars will look as big as the moon on that date, and that [...]
