NASA Funding Flows to Seven Small Businesses in Arizona

Leave a comment

NASA has selected its 2018 crop of small businesses to receive funding supporting innovation research and technology transfer, with seven awards going to Arizona.

The Small Business Innovation Research (SBIR) program and Small Business Technology Transfer (STTR) contracts, which total $43.5 million nationally among 348 awardees, support projects that promise to benefit both NASA’s mission and the U.S. economy.

An amateur astronomer from Rosario, Argentina, has accomplished an historic first: capturing the initial moments of a supernova explosion on film.

Although astronomers spot hundreds of supernovas each year, none had previously  spied the bright, brief moment when the shock wave first bursts out from the star’s interior — until now.

An amateur astronomer has picked up signals from a satellite NASA gave up for dead more than decade ago.

Scott Tilley was scanning the skies for secret military satellites when he picked up a transmission from the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite.

The Foggy Future of Refrigerants

Stable, nontoxic refrigerants changed the world, transforming food storage, expanding Sun Belt populations, even helping early movie theaters succeed. But they also wrecked the ozone layer — Earth’s shield against harmful ultraviolet radiation.

Today, as stockpiles dwindle — and prices rise — due to phase-outs set by the Montreal Protocols 30 years ago,  the future of Freon and its successors remains in doubt.

In honor of World Oceans Day (June 8), here’s my recent article on some of the remarkable discoveries made by marine biologists over the past few years. From clearing up the murky “lost years” of juvenile turtles to further solidifying our understanding of a jellyfish’s final fate, these delvers of the deep have shrunk what Shakespeare called “the vasty deep” to something a bit more fathomable but no less amazing. Find out more as I take a deep dive into …
