Beginning today, all Earth imagery from a prolific Japanese remote sensing instrument operating aboard NASA's Terra spacecraft since late 1999 is now available to users everywhere at no cost.

The River Nile and Delta

The new Sentinel-3A satellite recently began providing data from orbit. This very early image recorded on 3 March 2016, takes us over the River Nile and Delta and the surrounding desert areas of northeast Africa and parts of the Middle East.

56 years ago on 1 April 1960, the National Aeronautics and Space Administration (NASA) launched the Television Infra-Red Observation Satellite (TIROS-1), the world's first successful weather satellite. Weighing approximately 270 pounds and carrying two TV cameras and two video recorders, the satellite provided weather forecasters their first ever view of cloud formations as they developed around the globe.

The Russian Resurs-P No.3 satellite continues its in-orbit testing campaign and delivered its first photos of the planet, despite problems with one of the satellite's solar arrays that failed to fully deploy shortly after launch. Now in its operational orbit, the satellite will continue commissioning and calibration for several weeks before joining the Resurs-P No.1 and 2 satellites as part of the operational satellite constellation.

Satellite technology plays a crucial role in measuring greenhouse gas emissions globally, the heads of several space agencies agreed Sunday as they vowed to work together to develop a coordinated monitoring system.

European scientists are worried they could soon lose a vital tool for monitoring Earth's ice fields.
