An Earth-orbiting object cataloged as #32398 broke up on April 15, the U.S. Space Force’s 18th Space Defense Squadron tweeted on Tuesday (May 3). Sixteen pieces of space debris associated with the event are currently being tracked, the squadron added.
Object #32398 was an ullage motor from a space tug that helped deliver three Russian GLONASS satellites to orbit in 2007, according to journalist and author Anatoly Zak , who runs RussianSpaceWeb.com. (GLONASS is Russia’s version of the GPS navigation system.)

Legend has it that Isaac Newton first conceived of the concept of universal gravitation after an apple fell on his head, though the infamous piece of fruit may have actually just landed on the ground nearby.
This was the case for Thayne Currie, an astrophysicist at the NASA-Ames Research Center and the Subaru Telescope.
Team finds younger exoplanets are better candidates when looking for other Earths
"We know these radioactive elements are necessary to regulate climate, but we don't know how long these elements can do this, because they decay over time," said Dr. Cayman Unterborn, lead author of an Astrophysical Journal Letters paper about the research.
Studying exoplanets is challenging. Today's technology cannot measure the composition of an exoplanet's surface, much less that of its interior.
Would it be possible to fly a spaceship through a gas giant planet? | New Scientist
Although gas giant planets mostly consist of gas, at depth, the pressure means this gas behaves more like a liquid and, if you go deep enough, like a solid. In addition, rocky debris from other bodies that fell into a gas giant would accumulate at its core.
Nobody knows for sure what is deep inside a gas giant. Assuming that the ones in our solar system – Jupiter and Saturn – are typical examples, it wouldn’t be possible to fly through one due to the solid core, high temperature, high pressure and the difficulty in obtaining escape velocity.
