Atomic clock precision timing is essential for systems such as global navigation, satellite mapping, establishing the composition of exoplanets and the next generations of telecommunication. But atomic clocks are currently massive devices - weighing hundreds of kilograms - which need to be housed within precise, difficult-to-maintain conditions. That's why scientists around the world are racing First stars and black holes

Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes formed, which astrophysicists call primordial black holes.
Did primordial black holes help or hinder formation of the universe's first stars, eventually born about 100 Fermi confirms star wreck as source of extreme cosmic particles

Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA's Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place.
Fermi has shown that the shock waves of exploded stars boost particles to speeds comparable to that of light. Called cosmic rays, these particles mostly ta NanoAvionics extends its satellite bus range enabling advanced space missions

Lunar Zebro, a project of the Delft University of Technology in the Netherlands wants to build a robot and be the first Dutch and European rover to walk on the Moon. Their lunar rover does not only distinguish itself by its small size taking up the same area as an A4 sheet of paper, but also by its unique locomotion. Driven by C-shaped legs instead of wheels, the six-legged rover from where it takes its name in Dutch “zes-benige robot”, will be able to climb over much taller obstacles than its wheeled counterparts, making it ideal for
Gaia reveals the past and future of the Sun

We all wish that we could sometimes see into the future. Now, thanks to the very latest data from ESA’s star mapping Gaia mission, astronomers can do just that for the Sun. By accurately identifying stars of similar mass and composition, they can see how our Sun is going to evolve in the future. And this work extends far beyond a little astrophysical clairvoyance.

Sustained space exploration will require infrastructure that doesn't currently exist: buildings, housing, rocket landing pads.
So, where do you turn for construction materials when they are too big to fit in your carry-on and there's no Home Depot in outer space?
