Landolt Space Mission

St. Louis on the Air: NASA mission that seeks to put on artificial star in space is named after Metro East scientist

A $20 million NASA mission aims to put a small satellite into space that will make it easier for scientists to calibrate telescopes and more accurately measure the brightness of stars.

  • Scientists hope the enhanced measurements will help uncover secrets about dark energy, better determine the age of stars and assess the habitability of exoplanets.
  • The satellite will have eight lasers shining down on Earth that won’t be detectable by the naked eye, but telescopes will be able to find them.
  • The mission’s namesake, Arlo Landolt, is a renowned astronomer with roots in the Metro East.

USA Today: ‘How did we get here?’ NASA hopes ‘artificial star’ can teach us more about the universe

In a $19.5 million NASA-funded mission, researchers at George Mason University are heading a project to construct and eventually launch a small satellite into space.

  • Once in orbit, the so-called “artificial star” will be far enough away to look like a star to telescopes back on Earth.
  • The satellite will then begin the work of helping researchers study star brightness to gain more precise estimates of their size, scale and age.
  • By doing so, the researchers hope to uncover fresh clues about how fast the universe is expanding and, just maybe, whether life could exist anywhere else in the universe.
