Good News! Worms Make Babies in ‘Martian’ Soil

Mon, 12/04/2017 - 04:00

That’s the conclusion from biologist Wieger Wamelink who recently discovered two baby worms in his simulated Mars soil experiment. Since 2013, scientists from Wageningen University & Research have been growing crops in Mars and moon soil simulants designed by NASA. They’ve been successful in growing edible crops (including green beans, peas, tomatoes, potatoes, carrots, and more), according

Voyager 1 Fires Dormant Thrusters for the First Time in 37 Years

Fri, 12/01/2017 - 04:00
Man, they just don’t build ’em like they used to. The Voyager 1 spacecraft, launched in 1977, has fired up a pair of thrusters that haven’t been used for 37 years. Meanwhile, I’m on my third car in two years. The set of four small thrusters came online Wednesday after NASA engineers noticed the spacecraft’s attitude control thrusters had been degrading for several years. Those served to make minute adjustments to the craft’s orientation to keep its antenna po
