Rocket Engine Testing the NASA Way!

Stennis Space Center has long been known as the agency’s largest rocket testing facility and they have been extremely busy with the testing of the upgraded RS-25 engines. In fact all RS-25 Engine testing happens exclusively at Stennis Space Center! If these look familiar to you, it may be due to the fact that they were used as the space shuttle main engine for the last 30 years. Compared to the 3 RS-25 engines that the space shuttle had the SLS will utilize 4 of them to produce 2 Million pounds of thrust. The thorough testing of the RS-25 plays an essential role in upholding NASA’s high standards of efficient and reliable engines.

A computer simulation shows the collision of two black holes, a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO. LIGO detected gravitational waves, or ripples in space and time generated as the black holes spiraled in toward each other, collided, and merged. This simulation shows how the merger would appear to our eyes if we could somehow travel in a spaceship for a closer look. It was created by solvingdata.

The two merging black holes are each roughly 30 times the mass of the sun, with one slightly larger than the other. Time has been slowed down by a factor of about 100. The event took place 1.3
