Written by It was a simple pledge made amid the excitement of a landmark moment in space exploration: “We go together,” Bill Nelson, the head of Nasa, promised the world as the agency prepared to launch Artemis 1, its first moon-capable rocket in more than half a century. Now, nearly two years on from that successful uncrewed […]

In fact, bubble bursts caused by wave energy can release 100,000 metric tons of microplastics into the atmosphere each year. Since dolphins and other marine mammals breathe at the water’s surface, they may be especially vulnerable to exposure. Where there are more people, there is usually more plastic. But for the tiny plastic particles floating […]

But some of the most powerful tools for reducing flood risk are far more natural and widely recognizable: woodlands and green spaces. Trees offer much more than beauty and oxygen. Here’s how trees help […]
These missions require medium-lift rockets, or smaller rockets capable of a high-rate launch cadence to match the capability of a larger launch vehicle. In June, the Space Force selected SpaceX, ULA, and Blue Origin, Jeff Bezos’s space company, to compete for Lane 1 launch task orders. Military officials will add more companies to the pool […]
