Breakthrough in planetarium technology: high-end digital cinema projector turned into all-dome beamerUntil recently the technology in hand to project high-resolution still or even video images into a decent-sized planetarium dome, covering most of the complete half-sphere, was either inadequate, with low brightness and/or resolution or exceedingly expensive: Only a multi-million-$ laser projection system (namely Zeiss' ADLIB) could deliver striking resolution (16 Megapixels over the half-sphere), color depth and brightness. But now Zeiss and Sony have teamed up and introduced - to stunned audiences of some 150 planetarium professionals from all over the world - a system almost as good and yet cheaper and easier to install that is based on modern digital cinema projectors using SXRD technology, essentially a vastly improved version of the well-known liquid crystal display.Their chips deliver 8.9 Megapixels 24 times a second to meet the digital cinema standards, and a special 15-element lens developped in record time by Zeiss projects these pixels onto the dome: Only 2 of these projectors - now marketed as "4DOME" - are needed to cover the half-sphere. Together with more traditional DLP-based projection systems for medium-sized and small domes (the cute "TWINS", e.g., comes to you for just 100,000 Euros, inflatable 6-meter dome included), there are now (moderately) affordable solutions for every planetarium size. And while even 16 colorful Megapixels cannot mimic the brilliance and definition of a traditionally projected starry sky, a combination of a classical planetarium projector with a digital-cinema-derived alldome video projection system could well be the wave of the future.

ESA's CryoSat lost in Russian launch accidentThe failure of a Rockot rocket on October 8 has sent the European Space Agency's CryoSat ice research satellite crashing into the sea near the North Pole. Preliminary analysis of the telemetry data indicates that the first stage had performed nominally. The second stage also performed nominally until main engine cut-off was to occur. But due to a missing command from the onboard flight control system the main engine continued to operate until depletion of the remaining fuel. As a consequence, the separation of the second stage from upper stage did not occur: Thus, the combined stack of the two stages and the CryoSat satellite fell into the nominal drop zone north of Greenland close to the North Pole into high seas with no consequences to populated areas. An investigating commission by the Russian State authorities has been established to further analyze the reasons for the failure, results are expected within the next weeks. |

New distance record for a Gamma Ray Burst: redshift 6.3!Scientists using NASA's Swift satellite and several ground-based telescopes have detected the most distant explosion yet, a gamma-ray burst with a redshift of 6.29±0.01, shining towards us from the edge of the visible universe. This powerful burst was detected September 4, marking the death of a massive star and the possible birth of a black hole. It comes from an era soon after stars and galaxies first formed, about 500 million to 1 billion years after the Big Bang. Only one quasar and a handful of galaxies have been discovered at slighly greater distances, while the previous GRB recordholder had a redshift of 'merely' 4.5. The 6.3 of GRB 050904 mean that we see it at a time when the Universe was just 500 Myr old or 6.5% of its present age.This burst was very long, lasting more than 200 seconds, whereas most bursts last only about 10 seconds. The detection of this burst confirms that massive stars mingled with the oldest quasars. The detection also confirms that even more distant star explosions can be studied through combined observations of Swift and the network of world-class telescopes. Swift detected the burst and relayed its coordinates within minutes to scientists around the world: The infrared afterglow - there was nothing in the visible - was discovered rightaway by the Southern Observatory for Astrophysical Research (SOAR) telescope atop Cerro Pachon, Chile. An enormous redshift was likely from the beginning, and eventually the Subaru telescope on Mauna Kea, Hawaii, nailed it down with a spectrum. |

Hayabusa now at 7 km distance - and losing another reaction wheelWhile the Hayabusa spacecraft has successfully navigated itself into a new position only 6.8 km from Itokawa, the mission has run into trouble: a second reaction wheel has failed. This means that more fuel will be needed for attitude control via the thrusters, and so the whole mission profile - complex enough already - may require changes. Fortunately, Hayabusa has already nearly finished mapping asteroid Itokawa. "I hope it doesn't stop them from doing what they want to do with the mission, because it has a very neat design," the BBC is quoting one spacecraft expert. Few new pictures have been released in recent weeks, but an Oct. 4 Status Report finally contains some new close-ups from the 7-km position.
Hayabusa reaches asteroid Itokawa, great pictures from 20 kmThe Japanese asteroid probe Hayabusa (see Update # 254 lead) has arrived at its target asteroid on 1:00 UTC (S/C Event time) on Sep. 12: Now the spacecraft hovers around 20 kilometers away from asteroid Itokawa. Early photos show - in the words of JAXA - "contrast of rocky and hilly region and smooth area, which may suggest the origin of this asteroid. This feature may be a key to consider Itokawa's origin and evolution. The scientific observation will be conducted for about two months including sampling and topographic measurement." On August 28 the orbit maneuver of Hayabusa had been handed over from the ion engines to the bi-propellant thrusters. After the solar conjunction the microwave discharge ion engines had been turned on again at the end of July and accelerated with their full throttling so as to approach to the target. At the end of August Hayabusa had been still 4800km from Itokawa and was closing in at 32 km/h with the ion engines off. |

Nucleus of Tempel 1 fluffy, layered, crust-freeThe analysis of what happened during and after the first active experiment with a comet (see Update # 289 lead) is still in full swing, of course, a mere two months after the event, but at the world gathering of planetary scientists in Cambridge, UK, on September 7 lots of hitherto unknown details and also hints of a bigger picture were reported, including
