This eerie coloured orb is nothing less than the life-giver of the Solar System. It is the Sun, the prodigious nuclear reactor that sits at the heart of our planetary system and supplies our world with all the light and heat needed for us to exist.

Proba-2's Partial Solar Eclipse

n 8-9 March 2016, a solar eclipse took place over the Pacific Ocean.

Probing Vegetation Across the Globe

The first global map of vegetation from the recently launched Proba-V has been unveiled, demonstrating that the minisatellite is on track to continue a 15-year legacy of global vegetation monitoring from space.

Testing time for Proba-V

"ESA's Proba-V microsatellite is now assembled and midway through testing to ensure it is fully spaceworthy. The miniature Earth-observer, designed to chart global vegetation every two days, will be launched in April. The testing at the specialised Intespace facility in Toulouse, France, includes rigorous simulations of Proba-V's take-off conditions and the hard vacuum and temperature extremes it must endure in orbit. It comes after Proba-V's assembly was completed by prime contractor QinetiQ Space at its facility in Kruibeke, Belgium last month. Building it was a complex operation. Although smaller than a cubic metre, the satellites carries a wide-angle telescope for its main Earth-monitoring instrument, a pair of radiation sensors, a fibre optic connector experiment, a prototype radio transmitter based on the semiconductor gallium nitride, and a test receiver to track aircraft in flight all around the globe."

"An experimental camera smaller than an espresso cup on ESA's Proba-2 microsatellite caught this view of soon-to-be Hurricane Isaac as it moved west of the Florida coast into the Gulf of Mexico on Monday. The small satellite's X-Cam - Exploration Camera - acquired this image at 11:38:33 GMT on 27 August. At the time, Isaac was a tropical storm with maximum sustained winds of around 100 km/hr, with storm-force winds extending around 360 km from its centre. Isaac is expected to become a fully fledged hurricane during Tuesday, fed by the warm waters of the Gulf of Mexico. Less than a cubic metre in size, Proba-2's main mission focuses on observing the Sun and space weather." More.

Small But Agile Proba-1 Reaches 10 Years in Orbit, ESA

"A good photographer needs agility. So it is with ESA microsatellite Proba-1, which turns in space to capture terrestrial targets. Celebrating its tenth birthday this week, Proba-1's unique images are used by hundreds of scientific teams worldwide. A technology demonstrator turned into an Earth observation mission, the microsatellite - just a cubic metre in volume - has acquired nearly 20, 000 environmental science images with its main Compact High Resolution Imaging Spectrometer (CHRIS), used by a total of 446 research groups in 60 countries."
