A SpaceX Falcon 9 rocket transporting the TESS satellite lifts off from launch complex 40 at the Cape Canaveral Air Force Station in Cape Canaveral, Fla., Wednesday, April 18, 2018. The space telescope will survey almost the entire sky, staring at the brightest, closest stars in an effort to find any planets that might be …
NASA's Planet-Hunter TESS Has Just Been Launched to Check Out the Near Exoplanet Neighborhood
This column was written by my colleague Elizabeth Tasker, now at the Japan Aerospace Exploration Agency (JAXA), Institute of Space and Astronautical Sciences (ISAS). Trained as an astrophysicist, she researches planet and galaxy formation and also writes on space science topics. Her book, "The Planet Factory," came out last year. On January 5, 2010, NASA …
Diamonds and Science: The Deep Earth, Deep Time, and Extraterrestrial Crystal Rain
We all know that cut diamonds sparkle and shine, one of the great aesthetic creations from nature. Less well known is that diamonds and the bits of minerals, gases and water encased in them offer a unique opportunity to probe the deepest regions of our planet. Thought to be some of the oldest available materials …

The Just-Approved European ARIEL Mission Will Be First Dedicated to Probing Exoplanet Atmospheres
The European Space Agency (ESA) has approved the ARIEL space mission—the world's first dedicated exoplanet atmosphere sniffer— to fly in 2028. ARIEL stands for the “Atmospheric Remote-sensing Infrared Exoplanet Large-Survey mission.” It is a space telescope that can detect which atoms and molecules are present in the atmosphere of an exoplanet. The mission was …

A Reprieve for Space Science?
A quick update on a recent column about whether our "golden age" of space science and discovery was in peril because of cost overruns and Trump administration budget priorities that emphasized human space travel over science. The 2018 omnibus spending bill that was passed Wednesday night by the House of Representatives and Thursday night …

Space Science In Peril
NASA's decades-long success at enabling ground-breaking discoveries about our planet, our solar system, our galaxy, our origins and the billions of other planets out there is one of the crown jewels of our nation's collective inventiveness and will, and surely of our global soft power. Others have of course made major contributions as well. But …
