NASA Invites Media to Crew Completion of Yearlong Mars Simulation
They spent 378 days isolated inside a special habitat, pretending to be on a trip to Mars.
Why it matters This story shows how NASA is testing what astronauts might need to stay healthy on a long trip to Mars.
Discussion question What do you think would be the hardest part of living in a small space for more than a year?
Sculpture re-creates odd optical effects of famed Lycurgus Cup
Researchers at the University of Sheffield found a way to make a new sculpture with the same odd light effects as the Lycurgus Cup. The Lycurgus Cup is a very old glass cup that is about 1,600 years old. The team figured out how to recreate the ancient glass recipe that made the cup's colors change.
Why it matters This story shows how scientists can study old glass from long ago and use what they learn to make something new.
Discussion question What do you think scientists can learn from very old objects like the Lycurgus Cup?
The sunshade is 20 feet tall and 8 feet wide at its base. It will keep an infrared space telescope cool while the telescope looks for near-Earth asteroids.
Why it matters This sunshade helps the telescope stay cool so it can search for asteroids that come near Earth.
Discussion question Why do you think a space telescope needs to stay cool to do its job?
Engineers once added random bits on purpose to help these computer programs learn patterns. This randomness helped create deep-learning models, which sometimes make up wrong answers.
Why it matters This story shows how an unexpected choice by early AI builders led to the computer programs we use today.
Discussion question Why do you think engineers would add randomness to a computer program on purpose?
