Minor-Object News on 12 July '07
- Kitt Peak update: The Southwest Coordination Center news release (545Kb PDF) from this morning reports that "Firefighters on Wednesday completed building containment lines around the Alambre Fire... Fire managers say containment is at 80 percent." It notes favorable weather conditions and says some firefighting crews are being released for reassignment. At last check Kitt Peak National Observatory (KPNO) hadn't updated its previous statement on resuming operations tomorrow night, but at noon today said the visitor center will reopen to the public on Sunday.
- "August Meteor Shower Will Be 'A Great Show'," Space.com 12 July - Quote: "The annual Perseid meteor shower is expected to put on a great show this year, peaking in mid-August... The Moon will be out of the way, leaving dark skies for good viewing as Earth plunges through an ancient stream of comet debris."
- "New light cast on key chemical reactions in interstellar space," Argonne Natl. Lab 10 July - Quote: "[Scientists have] developed a detailed understanding of the dynamics of reactions between neutral radicals and neutral molecules, known as 'neutral-neutral' reactions, at temperatures as low as 20 Kelvin, approximately the temperature of interstellar space [using] a sample class of reactions (O3P + alkenes) that spans the range from non-reactive to highly reactive."
- "Students To Track Asteroids," New Mexico Tech 19 June - Quote: "For the next six weeks [three dozen top high school science students from 19 states plus Singapore] will spend their days in college-level lectures, and their nights imaging and measuring the speck of light from a distant asteroid... Working in teams of three, students will observe an asteroid with telescopes at Etscorn Observatory [MPC 719], measure its position precisely relative to nearby stars, then calculate its orbit using software they write themselves."
- "Good Morning, New Horizons!" NASA New Horizons mission 12 July - Quote: "Early this morning, New Horizons operators gently awakened the spacecraft from the two-week 'nap' that marked the mission's first operational step into hibernation mode... Hibernation reduces wear and tear on spacecraft electronics, lessens spacecraft-operation costs and frees up Deep Space Network tracking resources for other missions. New Horizons will 'sleep' in this spin-stabilized state for most of the remaining cruise to Pluto [arriving in 2015]; operators will wake New Horizons for about two months out of each year for system checkouts and instrument calibrations."
- "Near Sun Hibernation Mode," ESA Rosetta mission status report 11 July - Quote: "No activities have been conducted during the reporting period [9 June to 6 July 2007, besides four passive communication passes]... The Near Sun Hibernation Phase will last until the beginning of September [when] the spacecraft will be reconfigured back to Active Cruise Mode ... in preparation of the second Earth swing-by which takes place on 13 November 2007."
- "AKARI presents detailed all-sky map in infrared light," ESA 11 July - Quote: "Launched in February 2006, AKARI ... is a Japan Aerospace Exploration Agency (JAXA) project with ESA and international participation [performing] all-sky observations in six wavelength bands. More than 90 percent of the entire sky has so far been imaged. The mission provides the first census of the infrared sky since the atlas made by its only infrared surveyor predecessor, the Anglo-Dutch-US IRAS satellite more than 20 years ago... [One survey image, see above] shows the entire sky in infrared light at nine micrometres. The bright stripe extending from left to right is the disc of our own Milky Way Galaxy. Several bright regions corresponding to strong infrared radiation appear along or next to the Galactic Plane. These regions are sites of newly born stars."
NEOCP Activity on 12 July '07
The MPC's NEO Confirmation Page has 1 listing: 1 updated
When last checked at 2356 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one updated listing. Of these, none were "one nighters." So far Major News has counted a total of two objects listed on the NEOCP at some point today.
