Fascinating new images and enhanced video footage of the first humans on the moon were released this week. The grainy material, made available to commemorate the fortieth anniversary of the Apollo 11 voyage, serves as a stark reminder as to just how far technology has advanced in four decades. Today’s astronauts, for example, Tweet from space. Not even the most fevered imaginations of today’s premier developers can foretell what technology will be available to space travelers in 2049.
