NEO Surveyor, formerly called Near-Earth Object Camera (NEOCam), then NEO Surveillance Mission, is a planned space-based infrared telescope designed to survey the Solar System for potentially hazardous asteroids.
Puerto Rico's location near the Northern Tropic allowed the Arecibo telescope to view the planets in the Solar System over the northern half of their orbit. The round trip light time to objects beyond Saturn is longer than the 2.6-hour time that the telescope could track a celestial position, preventing radar observations of more distant objects.
Comet C/2023 A3 (Tsuchinshan-ATLAS), roughly 44 million miles away from Earth at the time of this photo. NASA Of course, astronauts also get front-row seats to the northern lights, aka the aurora ...
The discovery and tracking of space debris is a growing problem. Among the 20–30 thousand large objects in orbit that are tracked, an estimated 100 million objects some as small as paint flecks are harder to track than the larger objects, but large enough to shield against if they collide with a space asset.

The station is one of three [5] satellite communication stations in the NASA Space Communications and Navigation (SCaN) program’s Deep Space Network (DSN), whose mission is to provide the vital two-way communications link that tracks and controls interplanetary spacecraft and receives the images and scientific information they collect.
The space station is whizzing around Earth at about five miles per second (18,000 mph), according to NASA. That means time moves slower for the astronauts relative to people on the surface. Now ...
The subtle changes in time due to gravity’s denser passage on the Earth’s surface are a major reason why experts call for the moon to be given its own time zone — as even the planet’s best ...
The high-resolution mode used a 610 mm F 5.6 Panoramic lens manufactured by the Pacific Optical Company. The film was developed on-orbit, and then scanned by a photomultiplier for transmission to Earth.
