#den gegensinn erregt, Berlin, elfter September 2010

(Darmstadt, 8. Juli 2015) »Die Deutsche Akademie für Sprache und Dichtung zeichnet einen Autor aus, der sich mit einzigartiger Intensität zum Chronisten der Gegenwart und ihrer Kultur gemacht hat, als teilnehmender, denkender und moralisch urteilender Beobachter, der immer wieder neue Formen und Medien erprobt hat: Erzählung, Roman, Drama, Blog und Text-Bild-Collage. Rainald Goetz hat die deutsche Gegenwart der letzten dreißig Jahre beschrieben, zur Anschauung und zu Wort kommen lassen, er hat sie gefeiert und verdammt und immer wieder auch mit den Mitteln der Theorie analysiert. Hinter seiner nervösen, gespannten Erfahrungsbereitschaft stehen eine weite Bildung und ein empfindliches historisches Bewusstsein, die seiner Sprache eine Balance von leidenschaftlicher Expressivität, beobachtender Kühle und satirischer Deutlichkeit ermöglichen.«

Glitch-B-Gone: All Systems Go for New Horizons' Final Approach to Pluto by Alan Boyle, NBC News, Jul 6 2015, 7:12 pm ET

As NASA's New Horizons spacecraft enters the home stretch for its historic July 14 flyby past Pluto, the mission's managers say the glitch that briefly knocked the spacecraft offline over the Fourth of July weekend will never happen again.

If anything goes wrong between now and July 14, the probe's computer is programmed to reboot itself and pick up where it left off.

"Just like resetting your computer at home," Glen Fountain, the $728 million mission's project manager at Johns Hopkins University Applied Physics Laboratory, told reporters during a Monday teleconference.

Fountain and New Horizons' principal investigator, Alan Stern of the Southwest Research Institute, explained why the piano-sized spacecraft hit a "speed bump" on Saturday.

The fault occurred when New Horizons' primary computer was compressing previously acquired image data for more efficient storage on a recorder, at the same time that it was loading the detailed command sequence for the flyby.

"The computer was trying to do these two things at the same time, and the two were more than the processor could handle at one time, so the processor said, 'I'm overloaded,'" Fountain said. That triggered protective software that shut down communications with Earth, switched operations from the primary to the backup computer, and then re-established communications about an hour later in safe mode.

Fountain said that it only took about 15 minutes to diagnose the problem once contact was re-established. He said the image data that was being compressed over the weekend was richer than the "test pattern" data that was used for earlier simulations — and that probably contributed to the computer overload.

"These two events will not happen concurrently again," he said.

The process of restoring normal operations and getting back to gathering scientific observations has taken a couple of days, and there are a couple of reasons for that.

Firstly, the spacecraft is nearly 3 billion miles (5 billion kilometers) away. That means it takes 4.5 hours for signals to be sent to the spacecraft at the speed of light, and another 4.5 hours for the spacecraft to send back a response. Secondly, Stern said the team decided to concentrate on spacecraft recovery rather than trying to make the observations that had been scheduled for Sunday and Monday — in his words, to "focus on the cake and not worry too much about the icing."

About 30 observations went by the wayside, out of a total of 496 that had been scheduled to take place starting Saturday and going all the way out past the flyby. None of the mission's high-priority observations will be lost, Stern said.

Stern said the team had weathered nine safe-mode episodes during the nine years since New Horizons' launch, "so we've been in a familiar circumstance a number of times before."

"I probably should tell you I'm more nervous, but I'm not," he said.

New Horizons is currently less than 5.6 million miles (9 million kilometers) from Pluto and closing in at 30,000 mph (50,000 kilometers per hour). On Tuesday, the spacecraft is scheduled to begin a pre-programmed observational campaign for the encounter that will last until two days after the flyby.

During the time that New Horizons is in encounter mode, it won't go into safe mode if the computer encounters a problem. Instead, it will reboot and return to the pre-programmed time line. If the computer fails to execute a high-priority observational task due to a glitch, it will try again. "We make sure that if one trips, we have a backup," Stern said.

Stern noted that the July 14 flyby will take place on the 50th anniversary of the Mariner 4 probe's first successful flyby of Mars. "We will collect approximately 5,000 times as much data as Mariner 4, and for a first flyby reconnaissance, we're gonna knock your socks off," he promised.

Most of the data will be stored in the spacecraft's 128 gigabits of flash memory until after the encounter, and then sent back at an average rate of 2,000 bits per second. It'll take 16 months to transmit everything, Stern said.

"You've got to really be into delayed gratification if you want to be on this mission," he said.

After the teleconference, NASA released new pictures of Pluto that were based on data sent back between July 1 and 3, just before the glitch hit. The images show a swath of dark terrain around Pluto's midsection, breaking into what appears to be a series of regularly spaced dark spots.

"This object is unlike any other that we have observed," Stern said. "While Pluto has some similarities to Triton [Neptune's largest moon], it is not Triton. It looks like it has a much more complicated story to tell us."

New Horizons Returns to Science Ops July 7
A “Hard to Detect Timing Flaw” (a.k.a. "Leap Second") Found as the Cause of Safe Mode

This just in from NASA.gov:

"NASA’s New Horizons mission is returning to normal science operations after a July 4 anomaly and remains on track for its July 14 flyby of Pluto.

The investigation into the anomaly that caused New Horizons to enter “safe mode” on July 4 has concluded that no hardware or software fault occurred on the spacecraft. The underlying cause of the incident was a hard-to-detect timing flaw in the spacecraft command sequence that occurred during an operation to prepare for the close flyby. No similar operations are planned for the remainder of the Pluto encounter.

“I’m pleased that our mission team quickly identified the problem and assured the health of the spacecraft,” said Jim Green, NASA’s Director of Planetary Science. “Now – with Pluto in our sights – we’re on the verge of returning to normal operations and going for the gold.” 

Preparations are ongoing to resume the originally planned science operations on July 7 and to conduct the entire close flyby sequence as planned. The mission science team and principal investigator have concluded that the science observations lost during the anomaly recovery do not affect any primary objectives of the mission, with a minimal effect on lesser objectives. “In terms of science, it won’t change an A-plus even into an A,” said New Horizons Principal Investigator Alan Stern of the Southwest Research Institute, Boulder.

Adding to the challenge of recovery is the spacecraft’s extreme distance from Earth. New Horizons is almost 3 billion miles away, where radio signals, even traveling at light speed, need 4.5 hours to reach home. Two-way communication between the spacecraft and its operators requires a nine-hour round trip."

Bartholomeus Breenbergh: CIMON UND IPHIGENIA
1638. Öl auf Eichenholz. 60,3 x 53 cm
Mit einem Gutachten von Max J. Friedländer, Berlin, vom 28. November 1926, als „reizvolles, echt signiertes Werk von B. Breenbergh“ (im Original). 

EUR 30.000 – 50.000
US$ 33,500 – 55,800

Amor raubt keineswegs nur den Verstand. „Erwacher des schlafenden Geistes“, so nennt ihn Boccaccio in seinem ersten Gesang des V. Decamerone. Der Dichter veranschaulicht die „heilige Wirkung der Liebe“ anhand eines Exempels: Gales, gutaussehender Sohn eines Edelmannes, war so ungehobelt und unerzogen, daß die Menschen Zyperns ihn Cimone, gleichbedeutend mit Rohling, nannten. Cimones Dummheit ärgerte seinen Vater so arg, daß er den Jungen in die Wildnis schickte. Fernab der Zivilisation lebte er zufrieden bis er auf ein schlafendes Mädchen stieß, Iphigenie.

Ihre Schönheit verwandelt ihn vollkommen. Zum Erstaunen aller kleidet sich der einstige Dummkopf in hübschen Gewändern, knüpft tiefe Beziehungen, erlernt Musik, studiert Philosophie, dichtet und macht seiner Angebeteten den Hof. Der Augenblick des Verliebens ließ ihn schlagartig vom „Wilden“ zu einem besseren Menschen werden, und zum Schluß macht er die Schöne zu seiner glücklichen Frau.

Das Gemälde fällt in die Zeit der Wiederentdeckung antiker Literaturstoffe. Die mythologische „Novella“ Boccaccios begeisterte viele Zeitgenossen Breenberghs und in der Umsetzung war es sein absolutes Lieblingssujet - zwischen 1633 und 1647 hat er diese Szene mindestens siebenmal ganz unterschiedlich variiert.

In der Mitte unserer Fassung liegt Iphigenie, unbekümmert vermittelt sie den Eindruck sich zugleich hilflos hinzugeben und den unbehelligt beobachtenden Cimon lautlos verführen zu wollen. Wie in der literarischen Vorlage ist der Sohn vor Verzückung über den Anblick kontemplativ über seinen Stock gebeugt. Die Gruppe schlafender Frauen ist von besonders feinmalerischer Qualität und Breenbergh verleiht ihnen etwas sehr zartes, fast zerbrechliches. Subtil gelingt es ihm, mit dem sich über Iphigenie erstreckenden, aber abgebrochenen Torbogen der Ruine die sich anbahnende Verbindung zwischen dem zukünftigen Paar anzudeuten. Die lockere Behandlung der von Licht durchsetzten Landschaft ist von jener „zarten Duftigkeit“ (Wolfgang Stechow 1930), die typisch ist für jene Phase Breenberghs, in der nicht zufällig auch seine hochwertigsten Radierungen entstanden.

Meister von Frankfurt: MARIA MIT DEM KINDE
Um 1510. Öl auf Eichenholz. 36,6 x 28,5 cm

EUR 10.000 – 15.000
US$ 11,200 – 16,700

Wegen des Vergleichsbeispiels in Brüssel und ähnlicher Tafeln im Musée des Beaux-Arts in Poitiers sieht Didier Martens einen klaren Bezug zu dem Meister der Magdalenen-Legende. Peter van den Brink sieht hingegen in der Tafel – sowohl wegen der Gestaltung der Komposition als auch der Figuren – zweifelsfrei ein typisches Beispiel des Meisters von Frankfurt.
