The Days Are Numbered

messenger1dayleft

The days are numbered for the MESSENGER spacecraft and that number is 1. In one more day the MESSENGER spacecraft now out of fuel even out of helium that gas used to pressurize the fuel tanks is out.

Gravity wins again. MESSENGER will impact the surface of Mercury tomorrow. In the mean time data will still be taken. Over 500 images will be transmitted back home and believe it or not more than a thousand more images are on the recorder waiting in the queue. They will never be seen. As NASA says it is better to collect more data than can be transmitted than end the mission having been able to possibly have done more!

This image is about 7 km / 4.3 miles across with a resolution of 6.7 meters per pixel.
