Russia's Rassvet satellite constellation stalls far below planned orbit

Russia's Bureau 1440 has launched 32 Rassvet satellites in two batches this year, but none have reached their intended 500-mile orbit. Tracking data shows most satellites topped out near 300 miles, several stopped maneuvering entirely, and at least three have already reentered or appear headed for reentry.

SpaceX launches NASA's Nancy Grace Roman telescope, arriving months ahead of schedule

NASA's Nancy Grace Roman Space Telescope launched Sunday atop a SpaceX Falcon Heavy rocket, about eight months earlier than planned. The spacecraft separated successfully and is now heading toward the Sun-Earth L2 point, roughly 1 million miles away, where it will settle into a stable orbit alongside Earth over the next three months.

Orbital Congestion Forces SpaceX and Competitors Into Frequent Collision-Avoidance Maneuvers

Growing numbers of satellites and debris in low-Earth orbit are prompting SpaceX and other operators to repeatedly reposition spacecraft to avoid collisions. The increasing density of objects, ranging from active satellites to defunct hardware and fragments, is straining existing traffic-management practices.

NASA sets Sunday launch for Nancy Grace Roman Space Telescope via SpaceX Falcon Heavy

NASA is preparing to launch the Nancy Grace Roman Space Telescope on Sunday at 7:26 a.m. ET from Kennedy Space Center, using a SpaceX Falcon Heavy rocket. The telescope, arriving roughly eight months early and under budget, will travel to the Sun-Earth L2 Lagrange point about 1 million miles away after final inspections and fueling with 290 gallons of hydrazine.

Partial Lunar Eclipse Set to Cast Reddish Glow on Thursday Night

A partial lunar eclipse will unfold Thursday night into early Friday, with Earth's shadow covering roughly 93 percent of the moon's disk and giving it a reddish or orange tint. The partial phase lasts about three hours and 18 minutes, with the Americas offering the best viewing conditions since the peak occurs after dark there, while European observers will only catch a limited glimpse near dawn.

Interactive Tool Lets Users Explore Moon's Orbit and Phases in Real Time

A new interactive web feature allows users to view the Moon in 3D space, rotating and adjusting the date and time to see its craters and mountains from any angle. The tool also simulates the Moon's path across the sky as seen from any location on Earth, showing how its position and illumination change over a day.
