Today is our last day of measurements. We took a radiometer measurement in the morning, and then dug the final snowpit in the exact spot that the radiometer was viewing during the whole experiment. That way, we will know exactly what the radiometer was seeing. The pit measurements took hours and it was cold today […]
Here is how we “commute’” to the lab each morning. Dr. Noah Molotch (U. Colorado), Dr. Dan Berisford (JPL) Jen Petrzelka (U. Colorado), and Ty Atkins spent all day today (and the previous 2 days) making snowpit measurements using both traditional and new high-tech methods. In this photo, you can see how deep the snowpit […]
A big milestone today: after the DC snowstorm, the cross-country shipping, the snowcat trip up the mountain, and the days of wiring, we finally got radiometer data today. Dr. Mike Durand and Ty Atkins (U. Colorado) worked really hard to set up a stand built by Goddard engineers to hold the radiometer at just the […]
Sunrise on top of the mountain was beautiful—even the LN2 tank was glowing.
We finished the radiometer wiring today. The data logger we installed to record measurements isn’t working 100%, so we switched to a backup method. We worked so late, we had to stay the night on top of the mountain. The lab has bunks. It got quite cold outside at night, about -14C (7F), but not […]
I departed DC for Steamboat, still not knowing when things will arrive. While switching flights in Denver, I receive the shipping info: it’s supposed to arrive today!
We’re scheduled to start the field campaign next week, but Goddard has been closed since the previous Friday because of back-to-back snowstorms in Washington, DC. The last week before shipping out on a campaign is always hectic, but we were supposed to have shipped the equipment out days ago. We have lost a week to […]
Knowing how widespread and how deep mountain snow packs are is important for more than just making ski forecasts. One-sixth of the world’s population relies on melted snow for their freshwater, which means good estimates of snow are critical for making realistic predictions of a region’s water supply. But measuring snow, especially the amount of […]
Onlookers participate in LCROSS pre-impact activities at NASA’s AmesResearch Center. Credit: NASA The crowd at NASA Ames was poised and ready for impact as the LCROSS camera started sending back stunning images of the moon’s south pole. At impact, a flash or large plume wasn’t visible with the LCROSS camera, but even though we didn’t …
Scientist and engineers are adjusting LRO’s orbit to have it fly its closest approach to the Cabeus target site just 90 seconds after the Centaur impacts the lunar surface.
