ALT VOYAGER 1 JUST CAME BACK FROM THE DEAD Something thought to be broken for more than 20 years has suddenly come back to life on a spacecraft more than 15 billion miles from Earth. NASA’s Voyager 1, launched in 1977, recently faced another problem that could have threatened its ability to communicate with us. Engineers needed backup roll thrusters to help keep the spacecraft’s antenna precisely aimed at Earth. But those thrusters had been considered unusable since 2004 after their tiny heaters stopped receiving power. Then NASA engineers took another look at the old failure. They suspected the heaters might not actually be dead, but stuck in the wrong electrical state.

ALT I had never really stopped to consider what an extraordinary thing the Royal National Lifeboat Institution is. Think about it. A troubled ship calls for help, and eight people - teachers, plumbers, the guy who runs the pub - drop everything and put to sea, whatever the weather, asking no questions, imperilling their own lives, to try to help strangers. Is there anything more brave and noble than that? The RNLI - I looked this up later - is an organization run by volunteers, supported entirely by public donations. It maintains 233 stations around the coast of Britain and averages twenty-two call-outs per day. It saves 350 lives a year on average.

ALT Colorful nebula in space with a white haze throughout that is more concentrated in the center with a rippling effect. Colorful gas filaments appear to splash outward from the nebula center, colored yellow, magenta, and blue. A faint black border with right angles at the corners of the images show where the telescope’s field of view stopsdotted line with right angles shows the borders of the telescope’s image. Small white stars dot the background.
