Mike Brown, astronomer who ousted Pluto as a planet will speak Friday night at the UoA
The astronomer who was instrumental in ousting Pluto as a planet will tell that story Friday night at the University of Arizona. The debate is still being argued in scientific circles.
Mike Brown, from CalTech, speaks on “How I Killed Pluto and Why it Had it Coming” at 7:30 p.m. Friday at the UA's Integrated Learning Center, Room 120. The talk is free to the public.

Mars Phoenix Lander Finishes Successful Work On Red Planet
November 10, 2008 -- NASA's Phoenix Mars Lander has ceased communications after operating for more than five months. As anticipated, seasonal decline in sunshine at the robot's arctic landing site is not providing enough sunlight for the solar arrays to collect the power necessary to charge batteries that operate the lander's instruments.
Mission engineers last received a signal from the lander on Nov. 2. Phoenix, in addition to shorter daylight, has encountered a dustier sky, more clouds and colder temperatures as the northern Mars summer approaches autumn. The mission exceeded its planned operational life of three months to conduct and return science data.
The project team will be listening carefully during the next few weeks to hear if Phoenix revives and phones home. However, engineers now believe that is unlikely because of the worsening weather conditions on Mars. While the spacecraft's work has ended, the analysis of data from the instruments is in its earliest stages.
"Phoenix has given us some surprises, and I'm confident we will be pulling more gems from this trove of data for years to come," said Phoenix Principal Investigator Peter Smith of the University of Arizona in Tucson.
Launched Aug. 4, 2007, Phoenix landed May 25, 2008, farther north than any previous spacecraft to land on the Martian surface. The lander dug, scooped, baked, sniffed and tasted the Red Planet's soil. Among early results, it verified the presence of water-ice in the Martian subsurface, which NASA's Mars Odyssey orbiter first detected remotely in 2002. Phoenix's cameras also returned more than 25,000 pictures from sweeping vistas to near the atomic level using the first atomic force microscope ever used outside Earth.
"Phoenix not only met the tremendous challenge of landing safely, it accomplished scientific investigations on 149 of its 152 Martian days as a result of dedicated work by a talented team," said Phoenix Project Manager Barry Goldstein at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
Phoenix's preliminary science accomplishments advance the goal of studying whether the Martian arctic environment has ever been favorable for microbes. Additional findings include documenting a mildly alkaline soil environment unlike any found by earlier Mars missions; finding small concentrations of salts that could be nutrients for life; discovering perchlorate salt, which has implications for ice and soil properties; and finding calcium carbonate, a marker of effects of liquid water.
Phoenix findings also support the goal of learning the history of water on Mars. These findings include excavating soil above the ice table, revealing at least two distinct types of ice deposits; observing snow descending from clouds; providing a mission-long weather record, with data on temperature, pressure, humidity and wind; observations of haze, clouds, frost and whirlwinds; and coordinating with NASA's Mars Reconnaissance Orbiter to perform simultaneous ground and orbital observations of Martian weather.
"Phoenix provided an important step to spur the hope that we can show Mars was once habitable and possibly supported life," said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington. "Phoenix was supported by orbiting NASA spacecraft providing communications relay while producing their own fascinating science. With the upcoming launch of the Mars Science Laboratory, the Mars Program never sleeps."

New law allows salutes in civvies during anthem
10/31/2008 - WASHINGTON (AFNS) -- Veterans and servicemembers not in uniform can now render the military-style hand salute during the playing of the national anthem, thanks to changes in federal law that took effect in October.
"The military salute is a unique gesture of respect that marks those who have served in our nation's armed forces," said Dr. James B. Peake, secretary of Veterans Affairs. "This provision allows the application of that honor in all events involving our nation's flag."
The new provision improves upon a little known change in federal law last year that authorized veterans to render the military-style hand salute during the raising, lowering or passing of the flag, but it did not address salutes during the national anthem. Last year's provision also applied to servicemembers while not in uniform.
Traditionally, members of the nation's veterans service organizations have rendered the hand-salute during the national anthem and at events involving the national flag while wearing their organization's official head-gear.
The most recent change, authorizing hand-salutes during the national anthem by veterans and out-of-uniform military personnel, was sponsored by Sen. Jim Inhofe of Oklahoma, an Army veteran. It was included in the Defense Authorization Act of 2009, which President Bush signed Oct. 14.
