On October 17th, a NASA official speaking at an Astrophysics Advisory Committee meeting revealed that the European Space Agency (ESA) had begun “exploring options” and studying the feasibility of launching the Euclid near-infrared space telescope on SpaceX’s Falcon 9 rocket.

In a major upset, director Josef Aschbacher confirmed less than three days later that ESA will contract with SpaceX to launch the Euclid telescope and Hera, a multi-spacecraft mission to a near-Earth asteroid, after all domestic alternatives fell through.

The European Union and, by proxy, ESA, are infamously insular and parochial about rocket launch services. That attitude was largely cultivated by ESA and the French company Arianespace’s success in the international commercial launch market in the 1980s, 1990s, and 2000s – a hard-fought position that all parties eventually seemed to take for granted. When that golden era slammed headfirst into the brick wall erected by SpaceX in the mid-2010s, Arianespace found itself facing a truly threatening competitor for the first time in 15+ years.

The bad news is NASA estimates that it tracks only about 40 percent of the asteroids large enough that they could cause calamity if they were to hit Earth. To save us, the space agency needs fair warning — years, not months or weeks — to muster the defenses in space needed to safeguard the planet.

“As we say, we can’t do anything about them unless we know about them, and when they might be a concern for us,” Lindley Johnson, NASA’s Planetary Defense Officer, said in an interview.

Children’s hospitals in parts of the U.S. are seeing a surge in a common respiratory illness that can cause severe breathing problems for babies.

RSV cases fell dramatically two years ago as the pandemic shut down schools, day cares and businesses. With restrictions easing in the summer of 2021, doctors saw an alarming increase in what is normally a fall and winter virus.

Now, it’s back again. And doctors are bracing for the possibility that RSV, flu and COVID-19 could combine to stress hospitals.

With Project Convergence, the Army has sought to further its integration into the Joint Force and change the way it fights, with an eye toward greater speed, range, and accuracy — particularly for long-range precision fires. Army leadership is looking particularly to close the gaps around sensor-generated intelligence — specifically how it’s sensed, made sense, and acted upon.

To that end, Raytheon Intelligence & Space (RI&S) was selected in June for a competitive, prototype phase in the continued development of the Army’s Tactical Intelligence Targeting Access Node (TITAN) program. Awarded under an Other Transaction Agreement, TITAN seeks to turn battlefield intelligence into targeting information. A tactical ground station that finds and tracks threats to support long-range precision targeting, TITAN promises to bring together data from ground, air, and space sensors.

An international team of scientists has found toothed fish remains that date back 439 million years, which suggests that the ancestors of modern chondrichthyans (sharks and rays) and osteichthyans (ray-and lobe-finned fish) originated far earlier than previously believed.

The findings were recently published in the prestigious journal Nature.

The baby lambs didn’t just survive, they thrived. Within weeks in the artificial womb, they grew wool and gained weight. Are humans next?

Air conditioning is something you barely notice — until the power goes out, and it no longer works. But what if keeping cool didn’t require electricity at all?

A scientist has invented a material that reflects the sun’s rays off rooftops, and even absorbs heat from homes and buildings and radiates it away. And — get this — it is made from recyclable paper. The essential AC: Air conditioners are in 87% of homes in the United States, costing the homeowner $265 per year, on average. Some homes can easily spend twice that.

With global temperatures on the rise, no one is giving up their AC. More people are installing air conditioners than ever before, especially in developing countries where the middle class can finally afford them. 15 years ago, very few people in China’s urban regions had air conditioners; now, there are more AC units in China than there are homes.
