Breakthrough in planetarium technology: high-end digital cinema projector turned into all-dome beamer

Until 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 accident

The 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 wheel

While 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 km

The 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-free

The 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
  • a mean density of the nucleus of this comet of 0.6(+0.5/-0.3) grams per cubic centimeter, deduced for the trajectories of the ejected particles, which speaks of a very porous and fragile body which the projectile had no trouble dispersing at the impact site;

  • the lack of any hard crust (which would have caused a much brighter flash on impact), which is already being hailed as possibly the key insight of the whole experiment (and could be bad news for the Philae lander of the Rosetta spacecraft); and

  • the surface of the nucleus being devoid of any exposed water ice: It is significantly warmer at between 260 and 330 Kelvin. Only after the impact water ice and also more organic compunds were seen in the inner coma, evidence for a layered structure.
The mechanics of and sequence of events during the impact itself are now known in considerable detail, e.g. that
  • the impactor was hit by four dust particles, three small ones (1 to 10 mg) and a biggie (1/10 to 1 gram), shaking its orientation,
  • the impactor hit the surface at an angle of 20 to 35° to the horizontal (which was intentional; otherwise it might have disappeared into the ground too quickly),
  • there was first a thermal flash (seen by the flyby s/c and at least one video camera at a groundbased telescope), but much weaker than in comparable laboratory experiments (with a vertical gun at Ames), further evidence for the porosity of the nucleus,
  • then a fountain of molten silicates, 4 tons perhaps, shot out of the punched hole at 5 to 8 km/s, disappearing quickly,
  • and finally the much slower and bigger ejecta cloud formed while hidden underneath a gravity-dominated crater was forming over the next several minutes - the diameter can only be estimated at 102.0±0.3 meters.
All in all some 10 to 20,000 tons of material were ejected from the nucleus, including 3 to 6000 tons of dust - of which over 80% eventually fell back onto the nucleus, with the remainder plus all the gas escaping:
  • The brightness of the inner coma rose at that time, regardless of whether being watched by the OSIRIS camera on Rosetta or a (larger) amateur telescope on Earth, rather continuously for many minutes, though the slope of the light curve changed several times. This may be related to details of the crater formation.

  • This was also the time for the IR telescopes, namely the small one onboard the Deep Impact flyby s/c and the one on the Spitzer Space Observatory: They saw the emergence of many organic molecules not seen in the comet's coma before and obviously freed from the interior. Since the fluffiness of the nucleus makes for good isolation, the hopes are high that truly primordial matter is still among the transient cloud.

  • Then the light curve levelled off and returned to normal over the coming days, as did the chemical signatures in Tempel's spectrum: No new activity had been triggered, and the previously seen periodic changes in brightness continued in which the rotation (1.7 days) and perhaps higher effects manifest itself.
After the successful trajectory correction (see Update # 290 story 4) the flyby spacecraft is awaiting new orders: The formal process to initiate an extended mission to comet Boethin has hardly begun. But at least intense tests of the spacecraft systems and instruments have already shown that it is amazingly healthy and would be up to the task.
