According to NASA's article on the test, this is a big step toward sending a manned mission to Mars:

NASA successfully tested the first deep space RS-25 rocket engine for 500 seconds March 10, clearing a major milestone toward the next great era of space exploration. The next time rocket engine No. 2059 fires for that length of time, it will be carrying humans on their first deep-space mission in more than 45 years.

This is all part of a plan to send humans to Mars by 2030, which NASA has laid out in this beautifully illustrated image:

NASA released images of the recent solar eclipse. When seen from the Deep Space Climate Observatory (DSCOVR) it's just the shadow of the moon traveling across Earth. 

This is a first, according to Adam Szabo, NASA’s project scientist for DSCOVR: 

What is unique for us is that being near the Sun-Earth line, we follow the complete passage of the lunar shadow from one edge of the Earth to the other. A geosynchronous satellite would have to be lucky to have the middle of an eclipse at noon local time for it. I am not aware of anybody ever capturing the full eclipse in one set of images or video.
