A new NASA report shakes up lunar geology.
- The moon is indeed shrinking. It has been since it formed.
- The shrinking is producing thousands of fault lines.
- Archived seismometer data from Apollo missions show moonquakes.
How can we use the resources that are already on the Moon to make human exploration of the satellite as economical as possible?
If you were transported to the Moon this very instant, you would surely and rapidly die. That's because there's no atmosphere, the surface temperature varies from a roasting 130 degrees Celsius (266 F) to a bone-chilling minus 170 C (minus 274 F). If the lack of air or horrific heat or cold don't kill you then micrometeorite bombardment or solar radiation will. By all accounts, the Moon is not a hospitable place to be.
Think you've seen sand? You haven't seen sand.
- Microscopic photography exposes the beauty and strangeness of sand.
- Water wave action produces a startling variety of sand grains.
- That stuff between your toes is a lot more interesting than you might think.
Getting to close to a black hole is a nightmare waiting to happen.
- Like ocean tides caused by gravity, a nearby black hole would create a 'tide' inside your body, which is mostly water.
- As your body drew nearer to the black hole, your head would be stretched away from your feet.
- Scientists call this streching "spaghettification", from the word of spaghetti.
China's Chang'e 4 biosphere experiment marks a first for humankind.
- China's Chang'e 4 lunar lander touched down on the far side of the moon on January 3.
- In addition to a lunar rover, the lander carried a biosphere experiment that contains five sets of plants and some insects.
- The experiment is designed to test how astronauts might someday grow plants in space to sustain long-term settlements.
