NASA Wins Intergalactic Billiards Championship
The MESSENGER probe successfully completed its flyby of Venus, and heads towards Mercury.
Seriously, these guys are incredible. We want probes to get where they’re going fast, but going fast in space has one nasty implication: slowing down requires just as much energy as it took to speed up. In order to shed some of that speed, NASA sent their MESSENGER probe past extremely low by Venus to pass excess energy into Venus’ atmosphere.
Now the probe is heading on to do a flyby of Mercury, which will point it straight at the Sun. The technical ability this kind of feat requires is nothing short of astounding. It’s the world’s largest billiards trick shot, with the balls spaced 25 million miles apart.
