Seven astronauts died when the Space Shuttle Columbia disintegrated upon reentry on Feb. 1, 2003. NASA Deputy Administrator Pam Melroy looks back on the tragedy and how it shaped the agency.
A Japanese telescope captured images of the shape on Jan. 18. It was likely caused by the sun illuminating leftover fuel expelled from the rocket of a SpaceX launch.
NASA's Mars Reconnaissance Orbiter snapped the uncanny photo in December. Eyes are formed by craters. A hill with a "V-shaped collapse structure" resembles a snout.
There was no reason for alarm, as a NASA engineer called it "one of the closest approaches by a known near-Earth object ever recorded." It was only 2,200 miles above the Earth's surface.
The All-Domain Anomaly Resolution Office, formed last year to analyze UFO reports, is focusing on some 171 cases in which objects "appear to have demonstrated unusual flight characteristics."
The exoplanet was found using a satellite and spectrography. It has a similar size as Earth, but is much hotter and completes its orbit around its star in two days.
Virgin Orbit says its LauncherOne rocket "experienced an anomaly" just before it could deliver its payload. The problem arose shortly after a maneuver called the "barbecue roll."
Comet C/2022 E3 was first spotted last year and will draw nearest to the Earth in early February. The brightness of comets tends to be unpredictable, but astronomers say this one is promising.
Cunningham piloted the first manned Apollo mission, a key step in the drive to reach the moon, but he never flew in space again. He was a physicist who later became known as a climate-change skeptic.
One year ago, on Christmas Day, the James Webb Space Telescope was launched. Since it began collecting data, it has captured - in stunning detail - previously unobservable stars, planets and galaxies.
InSight's end has long been in sight, with NASA warning that it would likely be inoperative by the end of the year. The lander went quiet this weekend and shared a tweet it said might be its last.
