LISA launches, and using space as a resource to feed the world...

Farms use space resources to grow more food with less waste

Farming is not something most people would immediately associate with space exploration - unless you're thinking of Matt Damon's ill fated potato crop - but monitoring crops from space is actually one of the most important uses of space: Satellite data is used for everything from predicting draught conditions to showing which areas are producing the best (or worst) yields, and for working out why.
A new service called TalkingFields, developed with the assistance of ESA since 2010, aims to help farmers get the best from their land while cutting the environmental costs. Satellite data are fine-tuned to the needs of individual farmers by  combining optical satellite images with information from ground sensors, satnav and sophisticated crop growth models. It's not landing on a comet, or finding water on Mars, but this is just one of the ways that using space as a resource improves fundamental things about life back here on Earth.

"Agriculture is becoming a data-driven business," explains Heike Bach, CEO at Vista, the company behind TalkingFields. The satellite data also helps minimise environmental damage:. The runoff from overuse of nitrogen and phosphate can cause ground water pollution and vast seasonal algal blooms in the oceans. "We're targeting zero runoff," says Dr Bach. "Minimising the environmental cost of farming in this way is a real benefit to society."
ESA's Tony Sephton said: "There are existing services variously using Earth observation data, satellite navigation, farm management software and crop models, but TalkingFields combines them all."


ESA's LISA mission lauinches to hunt for ripples in space time

ESA's LISA mission launched today, on a mission to test the technology astrophysicists hope to use to hunt down gravitational waves, one of the last unconfirmed predictions of General Relativity.
