Nice launch! Showed more different camera angles and zooms than your typical Delta II launch. You gotta love that zoom shot with loads of condensation sticking to the vehicle. The combination of sound, tracking footage and cloudy skies reminds me of the New Horizons launch pretty much.

Any word when we will find out the winner of the naming contest?
good question hendric... hopefully soon as I need that new name for my upcoming article on this beauty of a space telescope |

Looked a bit unusual to me - blackening on the GEM's - and what looked like venting from the 1st stage shortly after launch. Doug I noticed that, too, and a colleague showed me it blackened the rocket all the way up to the fairing. I haven't watched a ton of Delta launches, but I don't recall ever seeing such an effect. EDIT: Sorry, misread your post. You weren't saying venting caused the blackening. Any thoughts on what might have? |

You weren't saying venting caused the blackening. Any thoughts on what might have? Looks like the solid booster backblast simply charred it. It's pretty chaotic from launch to launch - for example RocketCams on Delta II can get blasted with the charring at liftoff or can remain pretty clean. Just a stroke of luck I'd say. -------------------- |

Any news/hints when GLAST will be renamed ? I believe 60 days after launch. -------------------- |

Is that when the warranty expires?

GLAST blog:
"We're almost two weeks into the mission now, and things continue to go well, thanks to coordinated efforts across the team. Over the weekend, the spacecraft onboard attitude control software was further tested, with more challenging pointing sequences and autonomous repoints." |

NASA will hold a media teleconference on Tuesday, Aug. 26, at 2 p.m. EDT, to announce the first results from NASA's Gamma-ray Large Area Space Telescope and the observatory's new name. The telecon also will include the Large Area Telescope's first light results, and a presentation of gamma-ray bursts that the GLAST Burst Monitor has seen since it went into operation.

Fermi... Sounds like the last name of the lead singer of the music group, Black Eyed Peas (Fergie).
I'm assuming some of you are hip to pop culture as well -------------------- 2011 JPL Tweetup photos: http://www.rich-parno.com/aa_jpltweetup.html

Nov. 3, 2011 Trent J. Perrotto Headquarters, Washington 202-358-0321 trent.j.perrotto@nasa.gov RELEASE: 11-372 NASA'S FERMI FINDS YOUNGEST MILLISECOND PULSAR, 100 PULSARS TO-DATE WASHINGTON -- An international team of scientists using NASA's Fermi Gamma-ray Space Telescope has discovered a surprisingly powerful millisecond pulsar that challenges existing theories about how these objects form. At the same time, another team has located nine new gamma-ray pulsars in Fermi data, using improved analytical techniques. A pulsar is a type of neutron star that emits electromagnetic energy at periodic intervals. A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. This matter is so compressed that even a teaspoonful weighs as much as Mount Everest. "With this new batch of pulsars, Fermi now has detected more than 100, which is an exciting milestone when you consider that, before Fermi's launch in 2008, only seven of them were known to emit gamma rays," said Pablo Saz Parkinson, an astrophysicist at the Santa Cruz Institute for Particle Physics at the University of California Santa Cruz, and a co-author on two papers detailing the findings. One group of pulsars combines incredible density with extreme rotation. The fastest of these so-called millisecond pulsars whirls at 43,000 revolutions per minute. Millisecond pulsars are thought to achieve such speeds because they are gravitationally bound in binary systems with normal stars. During part of their stellar lives, gas flows from the normal star to the pulsar. Over time, the impact of this falling gas gradually spins up the pulsar's rotation. The strong magnetic fields and rapid rotation of pulsars cause them to emit powerful beams of energy, from radio waves to gamma rays. Because the star is transferring rotational energy to the pulsar, the pulsar's spin eventually slows as the star loses matter. Typically, millisecond pulsars are around a billion years old. However, in the Nov. 3 issue of Science, the Fermi team reveals a bright, energetic millisecond pulsar only 25 million years old. The object, named PSR J1823−3021A, lies within NGC 6624, a spherical collection of ancient stars called a globular cluster, one of about 160 similar objects that orbit our galaxy. The cluster is about 10 billion years old and lies about 27,000 light-years away toward the constellation Sagittarius. Fermi's Large Area Telescope (LAT) showed that eleven globular clusters emit gamma rays, the cumulative emission of dozens of millisecond pulsars too faint for even Fermi to detect individually. But that's not the case for NGC 6624. "It's amazing that all of the gamma rays we see from this cluster are coming from a single object. It must have formed recently based on how rapidly it's emitting energy. It's a bit like finding a screaming baby in a quiet retirement home," said Paulo Freire, the study's lead author, at the Max Planck Institute for Radio Astronomy in Bonn, Germany. J1823−3021A was previously identified as a pulsar by its radio emission, yet of the nine new pulsars, none are millisecond pulsars, and only one was later found to emit radio waves. Despite its sensitivity, Fermi's LAT may detect only one gamma ray for every 100,000 rotations of some of these faint pulsars. Yet new analysis techniques applied to the precise position and arrival time of photons collected by the LAT since 2008 were able to identify them. "We adapted methods originally devised for studying gravitational waves to the problem of finding gamma-ray pulsars, and we were quickly rewarded," said Bruce Allen, director of the Max Planck Institute for Gravitational Physics in Hannover, Germany. Allen co-authored a paper on the discoveries that was published online today in The Astrophysical Journal. Allen also directs the Einstein@Home project, a distributed computing effort that uses downtime on computers of volunteers to process astronomical data. In July, the project extended the search for gamma-ray pulsars to the general public by including Femi LAT data in the work processed by Einstein@Home users. NASA's Fermi Gamma-ray Space Telescope is an astrophysics and particle physics partnership. It is managed by NASA's Goddard Space Flight Center in Greenbelt, Md. It was developed in collaboration with the U.S. Department of Energy, with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden and the United States.
