Set for launch next month and codenamed "ËœMagISStra', the next ESA astronaut flight will see Italian Paolo Nespoli fly to the International Space Station for a six-month stay in space. Read the Bulletin and other publications online, with our visualizer tool. Read online    We follow Paolo through some of his training over the last two years, and look at the background of the mission, seeing why each of these flights is a remarkable team achievement involving...

Proba-2 is a small but innovative member of ESA's spacecraft fleet, crammed with experimental technologies. In its first eight months of life it has already returned more than 90,000 images of the Sun. Less than a cubic meter in volume, Proba-2 carries a new generation of miniaturized science instruments, focused on the Sun and space weather, as well as 17 state-of-the-art technology payloads.  Launched on November 2, 2009, Proba-2 began routine operations in February. A workshop at...

As ESA's SMOS mission nears the end of its commissioning, a new network will provide harmonized global datasets of soil moisture measurements collected from the ground, ensuring the data received from space are as accurate as possible. Making sure data delivered from space are accurate is a crucial aspect of any Earth observation mission. One way of achieving this is to take in situ measurements on the ground and compare them with the data being acquired by the satellite orbiting above....

While ESA's Proba-2 keeps its main instruments trained on the Sun, it is also looking back to its homeworld. This wide-angle view of Earth comes from an experimental camera that is smaller than an espresso cup. The Exploration Camera (X-Cam) is carried on the underside of Proba-2, one of 17 new technologies being tested by the mini-satellite. Observing in the visible and near-infrared with a 100° field-of"“view, its monochrome images resemble what an astronaut might see if elevated...

Polar skies glowed with ghostly auroras last week during the biggest geomagnetic storm of 2010. The event owed its origin to a solar eruption a few days earlier "“ revealed here in high-speed detail by ESA's small Sun-watcher Proba-2. Eruptions like this one have several components, most notably solar flares and Coronal Mass Ejections (CMEs). Solar flares are caused by sudden impulsive releases of magnetic energy from the surface of the Sun. The flare seen here took place at 11:54...

ESA has awarded a contract to Eurockot for the launch of two of its Earth observation missions. The first will be the next Earth Explorer: Swarm, a constellation of three satellites to study Earth's magnetic field. With the successful launch of the CryoSat-2 Earth Explorer less than 24 hours ago, this new contract highlights ESA's commitment to learning more about Earth from the vantage point of space. The contract covers the launch of ESA's Swarm magnetic-field mission and a 'ticket' for one...

Packed with novel devices and science instruments, Proba-2 is demonstrating technologies for future ESA missions while providing new views of our Sun. At a press conference on Tuesday at the Royal Observatory of Belgium in Brussels, the team behind the small satellite declared themselves extremely happy with its first three months in orbit and unveiled Proba-2's first solar observations. Since its launch on November 2, Proba-2's numerous subsystems have been switched on one by one and their...

Proba-2 is among the smallest spacecraft ever launched by ESA "“ less than a cubic meter "“ but it prepares technologies for future ESA missions, as well as giving scientists a new view of the Sun. Launched on November 2, 2009, Proba-2 is the result of European collaboration, with Belgian industry as a major participant. The objective of the mission is to test new spacecraft and instrument technology in space. The satellite is equipped with a quartet of new science...

The MIRAS instrument on ESA's SMOS satellite, launched earlier this month, has been switched on and is operating normally. MIRAS will map soil moisture and ocean salinity to improve our understanding of the role these two key variables play in regulating Earth's water cycle. "Following the switch-on, MIRAS is working beautifully well with all key subsystems, including all of the receivers, the optical fibers and the correlator unit, in perfect functioning condition," said ESA's Manuel...

Into its second week in orbit, Proba-2's spacecraft platform has proven to be in excellent health. This leaves the way clear for commissioning the many new technology payloads aboard the mini-satellite, among the smallest ever flown by ESA. As ESA's full-sized Soil Moisture and Ocean Salinity (SMOS) mission soared skyward by Rockot launcher on 2 November, it had a smaller companion. Piggybacking along was Proba-2, which occupies less than a cubic meter in volume with only one fifth of SMOS's...
