Good day all! Let's kick off the week with an incredible photo of rocket #science and #engineering at work on the A-1 Test Stand at NASA's Stennis Space Center in Mississippi. 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 hot fire marks the first test of an RS-25 flight engine for NASA’s new Space Launch System vehicle (SLS). 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.
