New Frontiers: U.S. Space Force, Zenno, and SpaceX Propel the Next Era of Space Innovation

The US Space Force is making headlines by awarding contracts to Viasat and Intelsat for new anti-jam communication satellites. These are part of a program to develop a jam-resistant satellite communication fleet, and it’s a pretty big investment—we’re talking hundreds of millions of dollars.On a global scale, there's some exciting news from Zenno Astronautics—they've become the first company to operate a superconducting product in space, which is a huge leap for space infrastructure technology.And if we zoom in a bit, there’s also a lot of buzz around SpaceX and its recent IPO. The company's shares have been soaring, and it’s causing a lot of excitement in the market.It’s definitely an exciting time in space industry!

Near-Earth asteroid pairs offer clues to composition, dynamics and environmental conditions of early solar system

Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth, making them potential collision threats. NEOs also offer clues to the composition, dynamics and environmental conditions of the early solar system and its evolution, and because they are relatively close to the Earth they lend themselves to astronomical measurements. Most NEOs are discovered in optical searches, but one crucial NEO parameter, its size, usually cannot be determined from optical detections alone. This is because an NEO's optical light is reflected sunlight, and an object can be bright either because it is large or because it has a high reflectivity. A CfA team has been using the IRAC infrared camera on Spitzer to measure NEO infrared emission signals which provide an independent measure of its size.
