High radiation on moon means lunar bases should be buried for safety

  • NASA recently unveiled the plan for its Artemis program, a series of missions that would return astronauts to the moon. 
  • A new study reveals how much radiation astronauts are exposed to on the lunar surface: a daily dose about 200 times greater than on Earth.
  • NASA wants to build a base on the moon, but the new data suggests it’d be safest to bury such a base under 2.5 feet of moon dirt to protect astronauts from radiation.

NASA wants to build a permanent base on the moon by the 2030s — a place astronauts could stay for extended visits at the lunar south pole.

But according to a new study, any astronauts who go there would face levels of radiation nearly three times higher than what the astronauts on the space station deal with. In high enough doses, long-term exposure to this

125 million-year-old dinosaur found buried by a volcanic eruption in China

The new species of burrowing dinosaur was discovered in the Lujiatun Beds, the oldest layers of the famous Yixian Formation in northeast China, according to a news release. Scientists believe that they were trapped by a volcanic eruption while resting at the bottom of their burrows.

“These animals were quickly covered by fine sediment while they were still alive or just after their death,” palaeontologist Pascal Godefroit of the Royal Belgian Institute of Natural Sciences, said.

The two preserved skeletons (A/B and C) of Changmiania liaoningensis. Red arrows indicate gastrolith, or stone clusters.

The scientist said that the effect would be very similar to what happened in Pompeii. The new species was named Changmiania liaoningensis, according to the news release. Changmian means “eternal sleep” in Chinese.

Scientists deduce that the ornithopod lived during the Cretaceous period and that it was a small herbivore that could run very fast, based on the length of its tail and its leg composition. It was about 1.2 meters (about 4 feet)
