Get out your red/blue glasses and check out this stereo scene from Taurus-Littrow valley on the Moon! The color anaglyph features a detailed 3D view of Apollo 17's Lunar Rover in the foreground -- behind it lies the Lunar Module and distant lunar hills. Because the world was going to be able to watch the Lunar Module's ascent stage liftoff via the rover's TV camera, this parking place was also known as the VIP Site. In December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours on the Moon, while colleague Ronald Evans orbited overhead. The crew returned with 110 kilograms of rock and soil samples, more than from any of the other lunar landing sites. Cernan and Schmitt are still the last to walk (or drive) on the Moon.

Coca Does Not Equal Cocaine

We have evidence that coca was consumed in what is today Ecuador as early as the 8000s BCE. This is hardly surprising. Coca is extremely useful.

The leaves contain a powerful alkaloid which acts as a stimulant. Its effects include raised heart rate, increased appetite, and suppressed hunger and thirst. Its muscle-relaxing properties mean coca leaves are great for menstrual cramps. And that also helps treat altitude sickness, but opening up the respiratory tract and relieving the feeling of shortness of breath and tightness in the chest. Further, coca leaves have antibacterial and analgesic properties. It also aids in digestion and preventing constipation. Finally, the leaves themselves are nutritionally beneficial. They are rich in iron, vitamin B, and vitamin C. No wonder coca leaves continue to be a large part of Andean culture through today.
