Space is getting crowded. More than 100 million tiny pieces of debris are spinning in Earth orbit, along with tens of thousands of bigger chunks and around 3,300 functioning satellites.
Large satellite constellations such as Starlink are becoming more common, infuriating astronomers and baffling casual skywatchers. In the coming decade, we may see many more satellites launched than in all Stratolaunch set for second hypersonic vehicle test

Aerospace company Stratolaunch's carrier aircraft, which is designed to launch hypersonic and space vehicles, is performing its second test flight in California's Mojave Desert, the company said on Thursday.
"We are airborne," the company said in a statement. "Currently performing various flight test maneuvers."
The aircraft will complete its test flight at about 2 p.m. Eastern Time New brain-like computing device mimics associative learning

Researchers have developed a computing device that is capable of learning by association, essentially merging storage and memory capacity.
Researchers at Northwestern University and the University of Hong Kong used organic electromagnetic chemical "synaptic transistors" to simultaneously store and process information, according to a study published Friday in Nature Communications.

Many meteorological satellite networks are constantly scanning Earth, providing vital research data and real-time life-saving weather information. Since China began its initial development in 1970, the Fengyun (FY) series of meteorological satellites have advanced considerably throughout more than 50 years.
While FY satellites primarily focus on the atmosphere, they are capable of observin Starry night at the Ariane 6 launch base

Europe’s new launch vehicle, Vega-C, is near completion. Elements will soon be shipped to Kourou for assembly and preparation for Vega-C’s inaugural flight.
This new launcher improves its Vega predecessor by offering more power and versatility at similar cost. This new design allows Vega-C to transport larger and heavier payloads into space making it a world-class competitor on the global launcher market while ensuring Europe’s independent access to space.

Satellites are leading the charge in the battle against climate change, providing critical insights about Earth that can only be gained from space. But are they also contributing to the problem?
Putting aside environmental impacts of the rockets that launch them to orbit, satellites inject a complex mix of chemicals into the atmosphere when their computers, fuel tanks and other onboard materials vaporize upon reentry.
Latin America looks to space, despite limitations on ground

Mars missions, astronauts coming and going at the International Space Station, China's increasingly ambitious space program. Space-related news is flowing, and not just from the world's richest, biggest nations. Take Latin America.
On Feb. 17, the congress in Nicaragua, one of the region's poorest, most conflict-prone nations, approved a law creating a space agency. Costa Rica, known for relative growth and stability, did the same on Feb. 18, the day that the NASA rover Perseverance landed on Mars to look for signs of ancient life.

Four astronauts left the International Space Station on Saturday aboard a SpaceX vessel, after more than 160 days in space which will culminate in a splash landing off the Florida coast.
The Crew Dragon capsule undocked from the ISS as scheduled at 8:35 pm (0035 Sunday GMT). With the flight back to Earth expected to take six-and-a-half hours, the crew was scheduled to splash down in the dark Egos clash in Bezos and Musk space race

Even the Milky Way seems too small to keep the egos of tech billionaires Jeff Bezos and Elon Musk from colliding as they vie to conquer space.
Musk aimed low with a recent tweet saying "can't get it up (to orbit)" in response to a post about Bezos-founded space company Blue Origin protesting NASA's choice of Musk's SpaceX team to build a module that will land the next US astronauts on the mo Small launchers - big market

Many new satellites are smaller and lighter than ever before. They are usually launched as 'co-passengers' together with other, larger satellites whose operators define the launch conditions. But a distinct class of launcher systems have now established themselves as a means to deliver small satellites into their target orbits as a primary payload - the microlauncher. In the USA and China, the m
