Could This be the Start of a New Space Shuttle? – All is not lost for the space shuttle idea. Richard Branson is thinking big again and along with orbital sciences Corp, Sierra Nevada Corp and some others they may build a reusable taxi to space just like the space shuttle. NASA will find $200 million to help with the development. -Weirdwrap

Bright White Storm Raging on Saturn – About a week ago, a bright white storm emerged on Saturn’s northern hemisphere, and amateur astronomer/planet astrophotographer extraordinaire Anthony Wesley from Australia has captured a few images of it. “This is the brightest Saturn storm in decades,” Anthony said on his website, Ice In Space. “If you get a chance to see it visually then take it, as it may be one of the rare “Great White Spot” (GWS) outbreaks on Saturn.” -Nancy Atkinson / Universe Today

Launch of TMA-20

Soyuz lift-off with ESA astronaut Paolo Nespoli together with Dmitri Kondratyev and Catherine Coleman for a challenging 6-month mission on the International Space Station (ISS) as members of Expeditions 26/27. They were launched in the Soyuz TMA-20 spacecraft from Baikonur Cosmodrome in Kazakhstan on 15 December at 19:09 GMT. Paolo’s MagISStra mission will be Europe’s third long-duration mission on the ISS. Between December 2010 and June 2011 he will be part of the ISS crew as a flight engineer. - Credit: ESA - S.

Phobos shadow passing over Viking 1 landing site dust storm (40x actual speed) - On September 28, 1977, Viking Orbiter 1 observed a dust storm over the site where it had dropped its lander, more than a year previously. As Viking 1 orbiter watched, the shadow of Mars' inner moon Phobos passed over the cloud tops. Data: NASA/JPL. Processing: Daniel Machá?ek

NASA Discovers Asteroid Delivered Assortment of Meteorites – An international team of scientists studying remnants of an asteroid that crashed into the Nubian Desert in October 2008 discovered it contained at least 10 different types of meteorites. Some of them contained chemicals that form the building blocks of life on Earth, and those chemicals were spread through all parts of the asteroid by collisions. -NASA

Near-Synchronous Explosions Connect Across the Vast Distances on the Sun – For several decades, scientists studying the sun have observed solar flares that appear to occur almost simultaneously but originated in completely different areas on the Sun. Solar physicists called them “sympathetic” flares, but it was thought these near-synchronous explosions in the solar atmosphere were too far apart – sometimes millions of kilometers distant – to be related. But now, with the continuous high-resolution and multi-wavelength observations with the Solar Dynamics Observatory, combined with views from the twin STEREO spacecraft, the scientists are seeing how these sympathetic eruptions — sometimes on opposite sides of the sun — can connect through looping lines of the Sun’s magnetic field. -Nancy Atkinson / Universe Today

Galaxy Cluster Reveals Farthest Known Galaxy – Almost all of the bright objects in this Hubble Space Telescope image are galaxies in the cluster known as Abell 2218 -a cluster so massive and so compact that its gravity bends and focuses the light from galaxies that lie behind it. As a result, multiple images of these background galaxies are distorted into long faint arcs. -The Daily Galaxy

No Asteroid Particles Found in Second Hayabusa Compartment, But More in First – No visible material from asteroid Itokawa was found inside the second compartment of a canister returned to Earth by the Hayabusa spacecraft. However, JAXA also announced that more micron-sized grains have been found in the first compartment, opened earlier this year. -Nancy Atkinson / Universe Today

93rd Birth Anniversary of Sir Arthur Clarke – Let’s cherish the 93rd birth anniversary of Sir Arthur Clarke, who rendered an immense service to the world, by means of his innovative concepts on telecommunication + thrilling scientific books, We should do something to remind the world about his being in a day like this, as what his imagination has rendered, continues to grow day by day -IYA 2009 / Sri Lanka

A Majestic Galaxy in One of the Largest Known Structures in the Observable Universe – This image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away, in the northern constellation Coma Berenices. The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. -The Daily Galaxy

Dec 14/15 Meteors (night after the Geminids peak) – What a difference 24 hours makes! Only a day removed from the Geminids peak and rates have crashed to a fraction of their peak. During the past 5 nights SALSA3 detected 12, 22, 69, 124 and now 20 Geminids. This is a characteristic of the Geminids in that the post-peak rates fall off much more rapidly than the pre-peak increase. -Carl Hergenrother

Soyuz and 3 ISS Crewmembers Return Home – The Expedition 25 crew landed safely in Kazakhstan at 11:46 p.m. EST Thursday (Friday 10:46 a.m. Kazakhstan time). The trio — Doug Wheelock, Shannon Walker and Soyuz Commander Fyodor Yurchikhin — undocked in the Soyuz TMA-19 at 8:23 p.m. ending their 5-1/2 month stay at the International Space Station. Staying behind on the orbiting laboratory are Expedition 26 Commander Scott Kelly and Flight Engineers Alexander Kaleri and Oleg Skripochka. -Nancy Atkinson / Universe Today

J-E-T-S, Jets, Jets, Jets! – It seems oddly appropriate to be writing about astrophysical jets on Thanksgiving Day, when the New York football Jets will be featured on television. In the most recent issue of Science, Carlos Carrasco-Gonzalez and collaborators write about how their observations of radio emissions from young stellar objects (YSOs) shed light one of the unsolved problems in astrophysics; what are the mechanisms that form the streams of plasma known as polar jets? Although we are still early in the game, Carrasco-Gonzalez et al have moved us closer to the goal line with their discovery. -Mike Simonsen / Universe Today

Could a Human Mars Mission Be Funded Commercially? – What will it take to actually get humans to Mars? The best answer is probably money. The right amount of cold, hard cash will certainly solve a lot of problems and eliminate hurdles in sending a human mission to the Red Planet. But cash-strapped federal space agencies aren’t currently in the position to be able to direct a mission to another world – at least in the near term – and seemingly, a trip Mars is always 20-30 years off into the future. But how about a commercially funded effort? -Nancy Atkinson / Universe Today

Jupiter and Uranus at opposition

Recorded on September 27, this well-planned composite of consecutive multiple exposures captured Jupiter and Uranus in their remarkable celestial line-up accompanied by their brighter moons. The faint greenish disk of distant planet Uranus is near the upper left corner. Of the tilted planet's 5 larger moons, two can be spotted just above and left of the planet's disk. At the right side of the frame is ruling gas giant Jupiter, flanked along a line by all four of its Galilean satellites. Farthest from Jupiter is Callisto, with Europa and Io all left of the planet's disk, while Ganymede stands alone at the right. - Credit: Peter Knappert / APOD

Expedition 21 safely home

December 1, 2009 13:51 by scibuff

Today, at 07:15 GMT, Soyuz TMA-15 spacecraft landed in Kazakhstan with members of Expedition 21 aboard. Soyuz Commander Roman Romanenko, European Space Agency Flight Engineer De Winne and Canadian Space Agency Flight Engineer Robert Thirsk spent 188 days in space, 186 of those aboard the orbiting International Space Station. The three arrived at the station in May as part of Expedition 20, which marked the start of six-person crew operations aboard the station. With their arrival, all five of the international partner agencies – NASA, the Russian Federal Space Agency (Roscosmos), the Japan Aerospace Exploration Agency (JAXA), the European Space Agency (ESA) and the Canadian Space Agency (CSA) – were represented on orbit for the first time.
