On a sunny February day at Dallas' Frontiers of Flight Museum, a cluster of students lifted telescope equipment out of a bulky briefcase. A sticker on the case read: "stand back—we're going to science!"

Using a compass and a spool of green thread for alignment, the students fastened their telescope on top of a tripod with the sun framed in view.

On April 8, they'll set up the telescope again, this time on a riverbank 140 miles south of Dallas. They'll be capturing images of the total solar eclipse, when the moon will appear to completely block the sun, causing a brief period of darkness called totality.

Their work will contribute to a national research project called the Citizen Continental-America Telescopic Eclipse 2024 experiment, or CATE 2024. Led by the Southwest Research Institute the project will task crews of volunteers with handling 35 telescopes along the U.S. path of totality, with four in North Texas.

Citizen science efforts like this one will take place across the country during the eclipse, and are designed to bring scientific research out of the ivory tower.

After a slightly extended stay on board the International Space Station, four astronauts from four international space agencies climbed aboard the SpaceX Crew Dragon Endurance and began their return trip to Earth.

Crew-7 is made up of NASA astronaut Jasmin Moghbeli, European Space Agency (ESA) astronaut Andreas Mogensen, Japan Aerospace Exploration Agency (JAXA) astronaut Satoshi Furukawa and Roscosmos cosmonaut Konstantin Borisov.

The quartet that launched from Kennedy Space Center back on Aug. 26, 2023 arrived to the ISS one day later to begin their 197-day stay, the second longest among the now eight completed SpaceX Crew Dragon trips so far to the ISS under NASA's Commercial Crew Program. Only Crew-2 in 2021 bested their stay, and by just one day.

They departed the station at 11:20 a.m. EDT and now have a more than 18-hour ride home. Depending on the weather, they are slated to splash down at one of seven target locations off the coast of Florida in either the Atlantic or Gulf of Mexico on Tuesday around 5:50 a.m. EDT with live coverage beginning on NASA TV at 4:30 a.m.
