Approaching Hartley 2

Approaching Hartley 2 Four images captured at about 09:20 every day for four days from October 29 to November 1 document the increasing brightness of Hartley 2 against the background star field as seen from Deep Impact, which was approaching for its November 4 flyby. The images have been rotated to align them. Credit: NASA / JPL / UMD / animation by Emily Lakdawalla

Deep Impact’s Hartley 2 Encounter Timeline – Close approach takes place at 13:50 UTC November 4, spacecraft event time. Find out what time this is in your time zone. –Emily Lakdawalla / The Planetary Society

NASA Mission in Final Day Before Comet Meetup – Mission controllers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., have relayed final instructions to their comet-bound spacecraft today, Nov. 3. The new programming will guide NASA’s EPOXI mission through its close approach with comet Hartley 2 –NASA/JPL

STS-133: Discovery scrubbed ahead of tanking for 24 hours – The Mission Management Team (MMT) have concluded their evalations on Thursday morning by deciding to scrub for 24 hours, due to unacceptable weather conditions. The decision came just prior to coming out of the hold for the loading of Discovery’s External Tank (ET-137). –NASA Space Flight

LHC to Recreate Conditions Just After Big Bang – So far, the Large Hadron Collider (LHC) has destroyed billions of protons by colliding them head-on inside its super-chilled detectors. Soon, however, the protons won’t be alone, lead ions — whole atomic nuclei — will be smashed up. Why? To recreate the conditions immediately after the Big Bang. –Ian O’Neill / Discovery News

Newly Discovered Comet 2010 V1 – IAUC 9175 brings surprising news of the visual discovery of a bright comet by two Japanese amateurs, Kaoru Ikeya and Shigeki Murakami. Visual magnitude estimates by the discoverers and Juan Jose Gonzalez of Spain place the comet between magnitude 7.5 and 9 with the brighter magnitude be more likely. The comet is currently a morning object in Virgo at an elongation of 32°. An orbit has yet to be published. -Carl Hergenrother / Transient Sky

Did Physicists Find Evidence of a Fourth Neutrino Flavor? – When neutrinos change from one phase to another, they tell us something about their mysterious nature. These ghostly subatomic particles come in three flavors, physicists say: muon, tau, and electron. Just this summer, a team caught a neutrino in the act of changing from muon to tau, a finding that backed up the argument that these particles do, in fact, have mass. This week, a new study of neutrino oscillation—the changing of flavors—suggests an deeper mystery, and implies that these three flavors of neutrino may not be enough to account these particles’ behavior. –Discovery Magazine Blogs

Gettin’ high on the Moon – How would you know how high up you are? Well, if you had the elevation data made by the the Lunar Reconnaissance Orbiter you’d be all set, because then you’d know that if you were at a latitude of 5.4125° and longitude of 201.3665°, you’d be on the highest spot on the Moon! –Phil Plait / Bad Astronomy

Night Lights

Constellations of lights sprawl across this night scene, but they don't belong in the skies of planet Earth. Instead, the view looks down from the International Space Station as it passed over the United States along the northern Gulf Coast on October 29. A Russian Soyuz spacecraft is docked in the foreground. Behind its extended solar panels, some 360 kilometers below, are the recognizable city lights of New Orleans. Looking east along the coast to the top of the frame finds Mobile, Alabama while Houston city lights stand out to the west, toward the bottom. North (left) of New Orleans, a line of lights tracing central US highway I55 connect to Jackson, Mississippi and Memphis, Tennessee. Of course, the lights follow the population centers, but not everyone lives on planet Earth all the time these days. November 2nd marked the first decade of continuous human presence in space on board the International Space Station. - Credit: ISS Expedition 25, NASA

Tension mounts as spacecraft approaches comet – The NASA/EPOXI team who will be managing and guiding their 3m spacecraft to within 700Km of the nucleus of Comet 103P Hartley/2 are now safely located at the Jet Propulsion Laboratory in Pasadena California, where the excitement is growing ahead of only the 5th close approach flyby of a comet in history. –Faulkes Telescope

Mystery of Saturn’s Wonky B Ring: Solved – It has long been known that Saturn’s rings are not the perfect hoops they appear as in small amateur telescopes, and when the Cassini spacecraft entered orbit around Saturn, the wonky disorder of the massive B ring became even more apparent. Scientists were stunned by towering vertical structures, scalloped edges on the rings, and odd propeller-like features. But scientists have now found the cause of these strange features: The region is acting just like a spiral galaxy, said Carolyn Porco, team lead of the Cassini imaging team. –Nancy Atkinson / Universe Today

NASA to Host Live Events for November 4 Comet Encounter – NASA will hold a series of news and educational events about the EPOXI mission’s close encounter with comet Hartley 2, scheduled to occur at approximately 14 UTC on Thursday, Nov. 4. The spacecraft will provide the most extensive observations of a comet in history –NASA/JPL

Two Fireballs Sighted from Comet Hartley 2 -Do They Signal a New Meteor Shower Display? – Astronomers have recorded sightings of two fireballs that may have come from Comet Hartley 2 that made its closest pass by Earth in 24 years this month, prompting speculation on whether the icy cosmic interloper may have a trailing a meteor shower show. –Daily Galaxy

Russians Toast Success of International Space Station – International Space Station will celebrate one more record in its orbital life on November 2, 2010 – 10 years of human space mission. Soyuz TM-31 docked to the station’s Zvezda module on Nov. 2, 2000. Since then, the crews have been constantly working in the orbital outpost. –Parabolic Arc
