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:

Ever wonder how your Grandpa would compare with an Olympian at their own sport?



Well, some scientists did, and they set up an experiment with seniors doing the same activities as Olympians and then measured the difference between the Olympian's record and the centenarian's. Specifically, Usain Bolt, who ran the 100-metre in 9.58 seconds...



...with, say, Donald Pellman, a competitor in the 100 to 104 age-group, who did the same event in 26.99 seconds, which was only a 64.5 percent decrease in performance compared with Bolt.

The centenarian athlete who showed the lowest percent decrease in performance between an Olympian and himself was Robert Marchand, a Frenchman, who holds the world record for his age group in 1-hour track cycling. He cycled only 50.6 percent slower than Bradly Wiggin's record.



After 40, our performance decreases by about 10 to 15 percent per decade usually, so you'd better start running now if you want to catch these Grandpas.

Sorry bro, your days of dominating everyone at beer pong are numbered.

Empire Robotics has created a robotic arm with a specialized ball on the end of it that hardens and softens to pick up objects.

So, for example, it can pick up ping pong balls and toss them into Solo cups.

Watch it flawlessly make 6 cups in a row in the video above, and – if you dare – challenge it in person at the 2015 Consumer Electronics Show (CES) in Las Vegas.

"The robot is not perfect, so it's possible for a human to win, but it's pretty good, so you'd have to be pretty good at beer pong," said the company's project manager John Dean.
