Glitch forces Japan's Hayabusa2 probe into 'safe mode'
(JAXA)
The Japanese asteroid-sampling spacecraft Hayabusa2 has been forced into protective "safe mode" while journeying through deep space. After delivering sample of Ryugu to Earth, the main spacecraft embarked on an extended mission to scope out yet another asteroid. Hayabusa2 is now headed for the small, near-spherical asteroid 1998 KY26, which it's expected to reach in 2031. But it is not currently plain sailing for the extended mission.

Double-star system with sideways exoplanet discovered
(ESO/L. CalΓ§ada)
Scientists have perhaps discovered the weirdest planetary system ever seen. Not only does this system feature the first-ever "polar planet" to be discovered, meaning the world exists on a sideways orbit, but that planet also circles around two stars. But that's not all - those parent stellar bodies are also brown dwarfs, better known as "failed stars."

This scientist helped build NASA's asteroid response plan
(European Space Agency)
Lindley Johnson has been a pioneer in blueprinting warning and response scenarios to any potential impact of Earth by an asteroid or comet. He led the establishment of the Planetary Defense Coordination Office at NASA in January 2016. Prior to NASA, he served 23 years of Air Force active duty working on a host of national security space systems.

Space.com talked with Johnson, the space agency's Planetary Defense Officer Emeritus, now in phased retirement mode, about his decades of work in shaping a global response and reaction to a rocky world smacking into our planet.

NASA astronaut Don Pettit will return to Earth on April 19
(NASA)
NASA astronaut Don Pettit and two cosmonaut colleagues will return to Earth from the International Space Station (ISS) on Saturday night (April 19), if all goes to plan.

The journey home for Pettit, Alexey Ovchinin and Ivan Vagner will begin Saturday at 5:57 p.m. EDT (2157 GMT), when their Russian Soyuz spacecraft undocks from the ISS' Rassvet module. The trio will touch down on the steppe of Kazakhstan, southeast of the town of Dzhezkazgan, just a few hours later, around 9:20 p.m. EDT (0120 GMT and 6:20 a.m. local Kazakh time on April 20). NASA will webcast the homecoming live, and Space.com will carry the agency's feed if it's made available.

(Robert Lea (created with Canva))
A new model of the cosmos does away with the universe's two most troubling and mysterious elements, dark energy and dark matter, collectively referred to as the dark universe. Here's the idea. The new concept replaces the dark universe with a multitude of step-like bursts called "transient temporal singularities" that erupt throughout the entire cosmos.
