Raumfahrt - Asteroid Vesta ist ein kleiner Planet!

 

You're beautiful, Vesta
NASA's UCLA-led Dawn mission shows protoplanet's surprising surface
Craters on Vesta
When UCLA's Christopher T. Russell looks at the images of the protoplanet Vesta produced by NASA's Dawn mission, he talks about beauty as much as he talks about science.
 
"Vesta looks like a little planet. It has a beautiful surface, much more varied and diverse than we expected," said Russell, a professor in UCLA's Department of Earth and Space Sciences and the Dawn mission's principal investigator. "We knew Vesta's surface had some variation in color, but we did not expect the diversity that we see or the clarity of the colors and textures, or their distinct boundaries. We didn't find gold on Vesta, but it is still a gold mine."
 
Dawn has been orbiting Vesta and collecting data on the protoplanet's surface since July 2011. Vesta, which is in the doughnut-shaped asteroid belt between Mars and Jupiter, is currently some 321 million miles from Earth.

Raumfahrt - China startet erfolgreich Trägerrakete mit Yaogan-XIIII-Satelliten

 

Carrier rocket Long March 4-B, carrying Remote Sensing Satellite No. 14, blasts off at Taiyuan Satellite Launch Center in north China's Shanxi Province, May 10, 2012. The Long March 4-B was launched at 3:06 p.m. and it also sent Tiantuo-1 Satellite into space. (Xinhua/Wang Shen)
China successfully launched the remote-sensing satellite Yaogan XIIII Thursday from Taiyuan Satellite Launch Center in the northern province of Shanxi, according to a press release from the center.
The satellite was carried into space aboard a Long March 4B carrier rocket which blasted off at 3:06 p.m. Beijing time, according to the center.
The satellite will be used to conduct scientific experiments, carry out surveys on land resources, monitor crop yields and help with natural disaster-reduction and prevention.
The Long March 4B carrier rocket was produced by China Aerospace Science and Technology Corporation. Thursday's launch is the 162nd mission of Long-March-series carrier rockets.
Along with Yaogan XIIII, a tiny satellite named Tiantuo I was also sent into orbit during the flight.
The satellite, weighing only 9.3 kg, will be mainly used for data reception for the satellite-based vessel Automatic Identification System, optical imaging and various space exploration experiments in orbit.

Astronomie - Herschel sieht Cygnus-X: der kühle Schwan mit glühenden Flügeln

 

 

 

This new view of the Cygnus-X star-formation region by Herschel highlights chaotic networks of dust and gas that point to sites of massive star formation.
The image combines data acquired with the PACS instrument at 70 micron (corresponding to the blue channel) and 160 micron (corresponding to the green channel) and with the SPIRE instrument at 250 micron (corresponding to the red channel). The observations were made on 24 May 2010 and 18 December 2010. North is to the lower-right and east to the upper-right.

An annotated version of Herschel’s view of Cygnus-X highlighting numerous dense sites of new star formation in the right-hand complex, and the swan-like structure in the left-hand portion of the scene. Powerful radiation and winds from thousands of stars in the OB2 complex undetected at Herschel’s long wavelengths have partly cleared and heated surrounding material, visible as the diffuse blue glow in the centre of the image. A supergiant star identified as G79.29+0.46 has likely ejected the ring of material seen at the bottom of the image.

Mars-Chroniken - HIRISE sieht Wander-Dünen auf Mars

 

 

Das Team um den US-Wissenschaftler Nathan Bridges von der Johns-Hopkins-Universität hat herausgefunden, dass sich die Sandberge in rund 100 Tagen um bis zu 4,5 Meter bewegen. Das berichtet das britische Wissenschaftsmagazin „Nature“. Die Entdeckung ist eine kleine Sensation, denn: Lange galten die Dünen auf dem Mars als uralte, unveränderliche Relikte aus einem längst vergangenen Zeitalter.

Die Forscher analysierten Aufnahmen der HiRISE-Kamera an Bord der Nasa-Sonde „Mars Reconnaissance Orbiter” (kann sogar 25 Zentimeter kleine Details erkennen). Im Abstand von 105 Tagen fotografierten die Astronomen ein Dünenfeld auf dem Mars. Die Aufnahmen zeigen Bewegungen, die denen von Wanderdünen auf der Erde ähneln.
Jetzt rätseln die Wissenschaftler, wie es zu den starken Sandbewegungen auf dem Mars kommt: „Bislang hatten wir gedacht, dass der Sand auf dem Mars recht unbeweglich ist. Diese Untersuchung ändert unsere Perspektive also völlig“, sagt Bridges.
Eine mögliche Erklärung: die geringere Schwerkraft auf dem Mars.

Raumfahrt - Vorbereitungen für nächsten Sojus-VS03-Start auf French Guiana

Soyuz Flight VS03
The launcher for Arianespace’s next Soyuz mission from the Spaceport in French Guiana is completing its initial checkout for a flight in the second half of 2012, which will carry another two spacecraft for Europe’s Galileo satellite navigation constellation.
During activity at the Spaceport’s Soyuz Launcher Integration Building – known by its Russian “MIK” designation – the vehicle’s four first-stage strap-on boosters have been mated with the Block A core second stage, followed by integration of the Block I third stage.
With its initial build-up concluded, the Soyuz is now undergoing regular maintenance checks that are standard for the Russian-built vehicles that have been in storage prior to their mission. Such verifications include testing of the launcher’s pneumatic and electrical systems.
This Soyuz will carry Europe’s next two Galileo In-Orbit Validation (IOV) satellites, joining the first pair of spacecraft lofted on Arianespace’s historic maiden flight of the Russian-built launcher from French Guiana in October 2011.
Once the four IOV satellites are in orbit, they will provide the minimum information needed for space-based navigation: latitude, longitude and altitude data, along with ranging accuracy; enabling assessment of the Galileo system’s performance, while also allowing suppliers to realistically check their receivers and services against actual signals.
Arianespace has been chosen to deploy the entire Galileo constellation of 30 satellites. This began with the launch of the first two experimental satellites, Giove-A and Giove-B, orbited by Arianespace’s Starsem affiliate on Soyuz launchers from Baikonur Cosmodrome in 2005 and 2007. Subsequently, Arianespace lofted the initial pair of In-Orbit Validation spacecraft on Soyuz’ October 2011 inaugural mission from the Spaceport.
The remaining 24 Galileo constellation satellites will be orbited through 2015, using six additional Soyuz vehicles carrying two spacecraft each, along with three Ariane 5s configured with four per launch.
Initial phases of the Galileo program were carried out by the European Space Agency (ESA) in activity co-funded with the European Commission. Galileo’s Full Operational Capability phase is being managed and funded by the European Commission, with ESA and the Commission having signed a delegation agreement by which the space agency acts as design and procurement agent.
The upcoming Galileo mission is designated VS03 in the numbering system for Arianespace’s launcher family – which is composed of the medium-lift Soyuz, heavy-lift Ariane 5 and light-lift Vega – all operated at the Spaceport. The “V” represents the French word for “flight” (Vol), while “S” signifies the use of a Soyuz launch vehicle. Its “3” denotes the third Arianespace mission of Soyuz from French Guiana.
