Back in 1957, something spectacular happened that would change the world forever: the first human-created satellite, Sputnik 1, was launched into space. Orbiting our planet in low-Earth orbit, its unique signatures could be seen across the world. Unlike the stars, planets, or meteors that illuminated the night sky, this artificial satellite would glow with the reflected light of the Sun, streaking across the skies overhead whenever it passed within a couple of hundred kilometers of an observer's location.
"There were claims of a tail, but since 3I/ATLAS is accelerating and its current size is not much larger than the angular resolution of Earth-based telescopes, it is not easy to avoid fictitious elongation of the image as a result of the object's motion."
NASA employees are preparing plans to terminate two critical satellite missions monitoring greenhouse gases, which provide valuable data to various sectors, including agriculture and science.
"Finding a temperate planet in such a compact system makes this discovery particularly exciting. It highlights the remarkable diversity of exoplanetary systems and strengthens the case for studying potentially habitable worlds around low-mass stars."
The twin spacecraft are part of the NASA-funded TRACERS mission, which will spend at least a year measuring plasma conditions in narrow regions of Earth's magnetic field known as polar cusps.
NASA announced that Makenzie Lystrup will leave her post as director of the Goddard Space Flight Center on Friday, August 1. Lystrup has held the top job at Goddard since April 2023, overseeing a staff of more than 8,000 civil servants and contractor employees, and a budget last year of about $4.7 billion.
NASA appears to be acting in accordance with a fringe, extremist ideology emanating from the White House Office of Management and Budget that asserts a right to impound funds appropriated by Congress for the sake of executive branch priorities.
