NASA asked people from around the globe to upload a selfie on Earth Day on social media so that a mosaic of the images with the globe could be created and posted on GigaPan at: http://www.gigapan.com/gigapans/155294

This spectacular image was built using 36,422 photos that were tagged #globalsefie in five humongous social media platforms around April 22, 2014. Here, people from more than 100 countries are all organized in a high quality rendering that people can zoom in and out of to see the selfies large or small.

Google has just unveiled a new online tool called Global Forest Watch that allows organizations and everyday people to monitor deforestation around the world. More than 40 organizations are collaborating on the site, which tracks the gain and loss of tree cover around the world using a combination of satellite data, crowdsourcing, and open data to show the state of the world’s forests in near real-time.

The site is designed to be easy to use and understand, showing separate maps of forest loss and gain over the present and past fourteen years, as well as maps of global tree cover, protected regions and conservation efforts, and more. Visitors to the site can view a map of the world for an idea of the big picture, or zoom in to see what’s happening in their own backyards.

There’s more the the site than simply giving visitors the ability to sit back and watch the world’s forests change, however. Global Forest Watch also wants to empower individuals, governments, companies, and NGOs to monitor logging operations. Corporations can use the tool to ensure their supply chain is sustainable, governments can identify illegal clearing operations, and residents in affected areas can report violators in their communities.

In late February, the Japan Aerospace Exploration Agency (JAXA) is teaming up with a fishing equipment company to test out an unusual approach to fighting space junk: a satellite equipped with a 300-meter magnetic net that will sweep up the man-made debris hovering in low Earth orbit. The net is only 30 cm wide when unspooled, and it is composed of a highly flexible metal fiber. When the net is launched into space, it will use a magnetic field to attract pieces of orbiting debris.

Over the course of a year, the collected space junk will sink lower and lower, eventually burning up in Earth’s atmosphere. If this test proves successful, a kilometer-long version has already been fabricated for future use. Jaxa is currently figuring out how to use space craft to attach these nets to larger pieces of space debris, like old rocket engines or broken satellites. A functioning system could be deployed as early as 2019.

Currently experts estimate there are 100 million bits of junk floating around the Earth. 22,000 of those pieces of space debris are believed to measure 10 cm or longer, potentially threatening satellites and the International Space Station. Most of the debris is made up of discarded parts of degrading satellites and old rockets.
