QuikScat Satellite to Monitor Sea Wind and Waves News [2014-07-08 13:33:30]  recommend  recommend this post  (20 visits) info

Using data from NASA’s QuikScat, weather forecasters were able to predict hazardous weather events over oceans 6 to 12 hours earlier than before these data were available. Orange areas show where winds are blowing the hardest and blue shows relatively light winds. Image credit:

Frying Pan Shoals off the North Carolina coast caught a gust to 99 mph on their weather station. They were in the eye-wall of Hurricane Arthur at the time. Here on the Delmarva Peninsula there is a real risk of extreme rip currents behind the storm. With thousands of folks streaming to the Maryland and Delaware beaches for the holiday weekend, this is a serious threat. Something to think about:

On the Planetary Society  website, the normally responsible and pro-science Planetary Society has posted an opinion piece by Louis Freedman and Tom Jones asking NASA to reconsider its refusal to fund the Asteroid Redirect Mission.  In short, this is a mission to kidnap a small asteroid from elsewhere in the inner solar system, and redirect it towards the earth, hopefully parking it in the

Has The Solar Cycle Peaked? NASA Says Probably. 

Dan\'s Wild Wild Science Journal [2014-06-11 02:35:32]  recommend  recommend this post  (27 visits) info
The 11 year solar cycle has apparently peaked, but it has been one of the weakest solar maxes of the modern era. The cycle is actually 22 years because at the end of 11 years, the sun’s magnetic field flips, and then flips again 11 years later. NASA has a video out today that explains more, and it’s important to note that some of the biggest solar storms can occur

I spent a little while looking at today’s images from NASA’s Terra and Aqua satellites with their amazing MODIS imager that sends back true colour images from an altitude of around 700 km. Here are a few things I spotted in just a short period of browsing this evening. Click any image for a much larger view. Here is a view of just some Sahara sand blowing north into Greece

Before you say, that’s cool and move on, think about that for a second. WE CAN MEASURE WINDS FROM SPACE! We can also measure temperatures,  humidity, the amount of dust in the air, and even how stressed the plants in a drought are. Oh, and NASA did it all (and went to the Moon and Mars, and launched 100 space shuttles), all on less money than we spent on the
