'The solar system on demand': HEO Robotics aims to push spacecraft imaging deep into the final frontier
October 28, 2025
An Australian firm leading the way in providing images of spacecraft in low Earth orbit is making moves to expand its capabilities to higher orbits — and possibly, in the long run, to solar system destinations.
HEO, also known as HEO Robotics, has made a splash with…
The amount of bandwidth provided by SpaceX’s Starlink satellites is limiting Ukraine’s ability to operate ground robots on the frontline of the nation’s war against Russia, forcing the beleaguered nation’s tech innovators to look for out-of-the-box…

A newly found space rock almost broke a speed record.
The asteroid, called 2025 SC79, has a pathway within the orbit of Venus that zips around the sun in only 128 days, making it the second-fastest unique asteroid orbit in the solar system, according to a statement from…
Potensic Atom 2 drone review
October 24, 2025
Potensic saw something of a renaissance with the launch of the Potensic Atom SE and then the Potensic Atom, which are both popular sub-250g folding drone models. The company moved away from larger drones to more compact and lightweight folding models and never looked back.
Building on this success and pushing features and functionality further, we now have the Potensic Atom 2, which is also a…
Super-Earth less than 20 light-years away is an exciting lead in the search for life
October 24, 2025
A super-Earth exoplanet in the habitable zone of its star has been detected less than 20 light-years away, putting it near the top of the list for best places to look for life beyond our solar system.
The planet, known as GJ 251c, orbits a red dwarf star 18.2 light-years…
Crystals used in applications as varied as lasers, LEDs and the semiconductors used in sensors found in astronomical instruments could someday be ‘drawn’ rather than ‘grown’, leading to higher performance and lower costs.
A team led by Elad Harel of…
Can we dim the sun to fight climate change? Not without risking weather patterns, scientists suggest
October 23, 2025
Some think it’s a no brainer: Scattering microscopic particles of sulfur into Earth’s atmosphere would reduce the amount of sunlight that reaches the ground, thereby cooling the planet. Indeed, this cooling might temporarily offset the progressing climate change — but a new study claims this type of intervention is likely to have several more unwanted side effects than previously…
