Last November, NASA's Voyager 1 sent home garbled data, and engineers traced the problem to the flight data subsystem (FDS). The problem turned out to be a single chip in the FDS memory. They couldn't repair the chip but could move the affected code into sections and store them in different parts of the FDS system. They tested the new system this week, sending signals to the Voyager 1, 22.5 light-hours away. It worked, and Voyager 1 is back.

Poor flatearthers with their "This is all CGI!" and "There is no space beyond the dome!". They will never experience the fascination and appreciation of science.
It's Official, Antimatter Falls Down in Gravity, Not Up
Since the discovery of antimatter decades ago, particle physicists have wondered if these particles were repulsed by gravity. Einstein predicted that despite having opposite charges to its regular matter counterparts, antimatter should still behave like matter does concerning gravity. This has been tricky to confirm experimentally since it's hard to make enough antimatter to observe its behavior. Particle physicists have finally pulled it off, using the ALPHA-g experiment at CERN, generating antihydrogen atoms and then dropping them in a 3-meter tall vertical shaft.

@fraser Does this also show that antimatter is attracted gravitationally to itself? eg if the earth was made of antimatter, would the antimatter in this experiment still fall downwards? (Or was this already known?)
@fraser Those folks are awesome
Amazing.
@fraser This is absolutely amazing!
