WELCOME to A/CC's prototype daily news publication designed to be the viewing end of a planned autonomous 24-hour news service. The new tools and this publication format are working well enough now to share with readers. It is expected that this approach will require less time to maintain than our previous news and small asteroid pages, which were retired on May 14th. There's still more development ahead and there probably will be some glitches along the way, but this is what's needed to keep up with the increasing pace of minor-object news. The CRT page will be maintained separately for a little while longer, until all of this is working smoothly. And the CRT and small-asteroid ephemerides will be kept going.
Minor-Object News on 19 May '07
- "Expendable Launch Vehicle Status Report," NASA/KSC 18 May - Quote: "Next week, the two spacecraft solar arrays ... will be attached to the Dawn spacecraft and undergo deployment testing. A solar array lighting test also will be performed before the arrays are stowed for flight... The spacecraft will be moved to Astrotech's Hazardous Processing Facility for fueling on May 26. The Delta II first stage will be hoisted into the launcher at Pad 17-B on May 23 and attachment of the nine solid rocket boosters will begin."
- "Streator honors its planetary pioneer," Peoria, Ill. Journal Star 19 May - Quote: "The Streator Township High School auditorium was packed Friday as the town kicked off the first Planet Pluto Expo."
- "P2E speaker: 'You can grow up to be what you want'," Ottawa, Ill. Times 19 May - Quote: "[Alan] Stern, recently named one of Time magazine's 100 most influential people, was responsible for spearheading the design and implementation of the probe that now is headed for Pluto -- carrying some of Tombaugh's ashes."
- "CU-Boulder To Partner With Cornell, Cal Tech On $100 Million Telescope In Chilean Desert," Univ. of Colorado at Boulder 17 May - Quote: "Newly forming stars and solar systems are surrounded by gas and dust, which block the escape of visible light but which radiate at [submillimeter] wavelengths."
- CCAT: See the Cornell Caltech Atacama Telescope Web site for more info. A page there on Solar System science explains that the telescope will allow "the detection of KBOs to sizes of order 100 km, making possibles a statistical investigation of both the size distribution and surface properties of those objects." And a page on Star Formation and Circumstellar Disks tells how "The majority of pre-Main-Sequence stars of low mass [less than three Solar masses] are thought to have circumstellar disks of gas and dust. These are the precursors of planetary systems [and] a key observational component for the study of the physics of these structures [will be] best observed in the submm regime."
- "Baby Stars Hatching in Orion's Head," Spitzer Space Telescope 17 May - Quote: "A new image from NASA's Spitzer Space Telescope shows infant stars "hatching" in the head of Orion... The region featured in the Spitzer image is called Barnard 30."
- SOFIA eNewsletter: The observatory's May 2nd newsletter to scientists reports that, "After completion of a few more test flights in Waco [Texas], SOFIA will be flown to DFRC at Edwards Air Force Base in California, probably in late May. There it is scheduled to undergo an extensive inspection before beginning further test flights in September."
NEOCP Activity on 19 May '07
The MPC's NEO Confirmation Page has 2 listings: 1 new, 1 updated
When last checked at 2351 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had one new and one updated listing. Of these, one was a "one nighter." Major News counted a total of six objects listed on the NEOCP at some point on this day.

Impact Risk Monitoring on 19 May '07
Notes for Today's Latest Risk Assessments
|2007 JZ20||JPL||1408||R E M O V E D||JPL: Risk listing removed at 1023 UTC.|
|NEODyS||1407||R E M O V E D|
For a list of all risk-rated objects recently in view, see our ephemerides page.
An impact solution, also known as a "virtual impactor" (VI), is not a prediction but rather a possibility derived from an orbit calculation that cannot be eliminated yet based on the existing data. Elimination can come quickly with just a little further observation or may take weeks or months, sometimes years. Once superceded or eliminated, a former impact solution has zero relevance to an object's risk. See Jon Giorgini's "Understanding Risk Pages" for more about all this.
