Amateur radio astronomer discovers long-lost satellite

In December 2005, NASA lost contact with the IMAGE satellite. After trying to reconnect for two years, the agency gave up. Over a decade later, hobbyist Scott Tilley was able to confirm that IMAGE is not only still in orbit, but also transmitting data. Tilley stumbled on the find while looking for another satellite named Zuma. Via the Washington Post : When Tilley caught a signal after a week of searching, on Jan. 20, he almost ignored it. Whatever it was, it was orbiting much higher than Zuma was supposed to be. There are hundreds of active satellites in space, most of which didn’t interest him. “I didn’t think of it much more,” he wrote on his blog. But as he continued to scan for Zuma, he came across the signal again — stronger this time — and out of curiosity checked it against a standard catalogue. The signal matched for IMAGE. But IMAGE was supposed to be dead. Tilley had to Google the old satellite to find out what it was, as it had been all but forgotten on Earth. Eventually, he came across a decade-old NASA report on the mission’s failure. “Once I read through the failure report and all the geeky language the engineers use, I immediately understood what had happened,” Tilley told Canadian Broadcasting Corp. News. Then he rushed to contact NASA himself. • NASA’s IMAGE RECOVERY

Researchers infuse plants with chemicals to glow for hours

MIT researchers have figured out how to infuse common plants like watercress and arugula with luciferase, the chemical that makes fireflies glow. The process make the plants emit a dim glow for up to four hours. Via MIT : Previous efforts to create light-emitting plants have relied on genetically engineering plants to express the gene for luciferase, but this is a laborious process that yields extremely dim light. Those studies were performed on tobacco plants and Arabidopsis thaliana, which are commonly used for plant genetic studies. However, the method developed by Strano’s lab could be used on any type of plant. So far, they have demonstrated it with arugula, kale, and spinach, in addition to watercress. For future versions of this technology, the researchers hope to develop a way to paint or spray the nanoparticles onto plant leaves, which could make it possible to transform trees and other large plants into light sources. “Our target is to perform one treatment when the plant is a seedling or a mature plant, and have it last for the lifetime of the plant,” Strano says. “Our work very seriously opens up the doorway to streetlamps that are nothing but treated trees, and to indirect lighting around homes.” • Engineers create plants that glow (MIT)
