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 Landolt Space Mission will put the so-called artificial star 鈥 that鈥檚 about the size of a microwave 鈥 into Earth鈥檚 orbit in 2029. The satellite will have eight lasers shining down on Earth that won鈥檛 be detectable by the naked eye, but telescopes will be able to find them.
The mission鈥檚 namesake, Arlo Landolt, is a renowned astronomer with roots in the Metro East.
Growing up in the 1940s in Madison County, Illinois, Landolt attended a one-room country schoolhouse about a mile from his home where eight grades were taught by one teacher. On cold winter mornings, his mother would send him to school with a baked potato in each pocket to help keep him warm.
鈥淗e was always very interested in nature and therefore science. I know he participated in 4-H club when he was a youngster,鈥 said Landolt鈥檚 daughter Jennifer Boutte, a chemistry instructor at St. Louis Community College-Forest Park.
Through 4-H, Landolt raised and sold hogs. With the proceeds, he bought a set of Funk & Wagnalls Encyclopedia and read them cover to cover.
Landolt went to high school in Highland, Illinois, and after earning a Ph.D. from Indiana University, started his career at Louisiana State University. While a professor at LSU, he put together widely used catalogs of stellar brightness in the 1970s through the '90s.
Boutte recalls a 鈥渨onderful family experience鈥 growing up. She was the youngest of five daughters in a blended family. When Landolt married a high school classmate, Eunice Casper, she already had four daughters.
鈥淭here was a lot of camaraderie,鈥 Boutte said. 鈥淲e talked about nature and science. My mom [was] a nurse. Of course, it was chaotic with five girls 鈥 all girls 鈥 in the family. My father tended to just keep his head down and go with the flow of things.鈥
Boutte credits her father, who died in 2022, with helping foster a love of science.
鈥淟SU used to have a small observatory about 45 minutes, maybe an hour, outside of Baton Rouge, Louisiana, and I would go spend time with him there. He would be observing, and I'd play in the dormitory area and we'd spend the night there,鈥 Boutte said. 鈥淗e'd let me move the telescope around a bit, and I could ask questions. And he was always wonderful to share information with me. I probably just didn't ask enough questions.鈥
