Cold Layer in the Atmosphere of Venus

Venus Express has spied a surprisingly cold region high in the planet's atmosphere that may be frigid enough for carbon dioxide to freeze out as ice or snow.

Fireworks in the Early Universe

Galaxies in the early universe grew fast by rapidly making new stars. Such prodigious star formation episodes, characterized by the intense radiation of the newborn stars, were often accompanied by fireworks in the form of energy bursts caused by the massive central black hole accretion in these galaxies.

ATV Undocking Postponed

The undocking of ATV-3 from the International Space Station late last night was postponed due to an incorrect command. During operations ATV-3 performed perfectly in line with its pre-defined measures.

Cavenauts return to Earth

The international team of astronauts taking part in ESA's caving adventure have returned to Earth after spending six days underground. The voyage to the surface of our planet took them five hours from basecamp.

European CanSat Competition

"Students in different age groups are being invited by ESA to participate in three educational programmes that will take place during 2013. Each programme is an exciting opportunity to design an experiment and conduct scientific research. ESA is now inviting proposals for the Spin Your Thesis! campaign. This programme enables university students to carry out experiments in hypergravity, using the Large Diameter Centrifuge at the Agency's ESTEC space research and technology centre in the Netherlands. It is open to undergraduate students and those following a Masters or PhD course. Up to four teams will be selected. The deadline for proposal submissions is 10 December. Another call is for the European CanSat competition. The CanSats, similar in volume and shape to a soft-drink can, will be launched on a small rocket from the Netherlands. The primary task of each CanSat will be to measure atmospheric temperature and pressure during the flight." More

ESA's CAVES: Going Underground

ESA's CAVES training programme began its second phase last Friday as six astronauts ventured into the Sardinian caves in Italy that are their home this week. CAVES mimics elements of spaceflight to prepare astronauts and trainers for the real thing.

World Quantum Teleportation Record Broken

"An international research team using ESA's Optical Ground Station in the Canary Islands has set a new distance world record in 'quantum teleportation' by reproducing the characteristics of a light particle across 143 km of open air. Funded by ESA, researchers from Austria, Canada, Germany and Norway transferred the physical properties of one particle of light - a photon - onto its 'entangled' partner via quantum teleportation, thereby bridging a distance of 143 km between the Jacobus Kapteyn Telescope on La Palma and ESA's Optical Ground Station on adjacent Tenerife. Their results have been published in this week's Nature Magazine. Once entangled, the measurement of a certain property - such as polarisation or spin - will yield the same result for both particles, no matter how far apart the particles are located, and without any further signal being physically passed between them. Quantum teleportation is not copying in the strictest sense however, since the act of transference destroys the original particle - its characteristics passing to its entangled counterpart." More

Insight into Martian Geology

Recently engaged in providing support to the successful landing of NASA's Mars Science Laboratory "Curiosity", ESA's Mars Express has now returned to its primary mission of studying the diverse geology and atmosphere of the Red Planet from orbit.

"Winners of the YouTube Spacelab competition will get to see their experiments in space on 13 September. ESA astronaut Frank De Winne will participate in the live event, transmitted from the International Space Station to the world via YouTube. Frank De Winne, Head of the European Astronaut Centre, acted as one of Europe's jurors of the international student competition. NASA, YouTube, ESA and Lenovo today announced the culmination of the YouTube SpaceLab competition in which astronauts will reveal the results of the two winning experiments live from the International Space Station and share them online on YouTube. The livestream will connect the Station to YouTube's London studio on Thursday, 13 September beginning at 13:30 GMT (15:30 CEST)." More.

"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.

Astronauts dream of finding new life and for a select crew that dream might be within reach this week - albeit deep underground instead of in outer space.

Star Clusters on a Collision Course

Astronomers using data from NASA's Hubble Space Telescope caught two clusters full of massive stars that may be in the early stages of merging.

Phobos in 3D

Some 135 years after its discovery, Mars' largest moon Phobos is seen in fantastic detail - and in 3D - in an image taken by ESA's Mars Express spacecraft as it passed just 100 km by.

I recently had a chance to ask Dr. Alexander Kumar a few questions about his experiences in Antarctica - and elsewhere - as they related to space exploration - and exploration in general.

Turning its eye to the Tarantula Nebula, the NASA/ESA Hubble Space Telescope has taken this close-up of the outskirts of the main cloud of the Nebula.

Today, the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument on MSG-3 captured its first image of the Earth. This demonstrates that Europe's latest geostationary weather satellite, launched on 5 July, is performing well and is on its way to taking over operational service after six months of commissioning.

ESA's Mars Express has observed the southern part of a partially buried approx. 440-km wide crater, informally named Ladon basin.

A year ago, the largest and most complex scientific instrument on the International Space Station was delivered to the orbital outpost. Searching for antimatter and the origins of our Universe, it is working flawlessly thanks to the continuous support from its own 'mission control'.

Polar View (Norway) has carried out this GSP study comparing the needs of Arctic stakeholders (as articulated in policies and strategies) with the contribution different types of satellite technologies can make to meet current and future requirements.
