New Asteroid Families Discovered
May 29, 2013
Astronomers using data from NASA's Wide-field Infrared Survey Explorer (WISE) have identified 28 new families of asteroids. The findings are a critical step in understanding the origins of asteroid families, and the collisions thought to have created these rocky clans.
"We're separating zebras from the gazelles," said Joseph Masiero of NASA's Jet Propulsion Laboratory in Pasadena, Calif., who is lead author of a report on the new study that appears in the Astrophysical Journal. "Before, asteroid family members were harder to tell apart because they were traveling in nearby packs. But now we have a better idea of which asteroid belongs to which family."

March 1, 2013 Something unexpected is happening on the Sun
2013 is supposed to be the year of Solar Max, the peak of the 11-year sunspot cycle. Yet 2013 has arrived and solar activity is relatively low. Sunspot numbers are well below their values in 2011, and strong solar flares have been infrequent for many months....
Given the tepid state of solar activity in Feb. 2013, a maximum in May now seems unlikely.
"We may be seeing what happens when you predict a single amplitude and the Sun responds with a double peak," comments Pesnell." Solar News
Streambed on Mars
Mars Rover "Curiosity" finds streambed on Mars
Sept 27, 2012
Sept. 27, 2012: NASA's Curiosity rover mission has found evidence a stream once ran vigorously across the area on Mars where the rover is driving. There is earlier evidence for the presence of water on Mars, but this evidence -- images of rocks containing ancient streambed gravels -- is the first of its kind.

On July 15, NASA's ion-propelled Dawn probe will become the first spacecraft to enter orbit around a main-belt asteroid. Dawn will orbit Vesta for one Earth-year, studying the giant space rock at close range to help scientists understand the earliest chapter of our solar system's history.
As Dawn approaches Vesta, surface details are coming into focus, as seen in a recent image taken from a distance of about 26,000 miles (41,000 kilometers)....

An intimate exploration of the asteroid Vesta. 2011 will be the year when we gain a deeper understanding of Vesta--asteroid of focus, dedication and commitment--thanks to NASA's DAWN. This will bring a signifcant astrological emphasis to Vesta, and her role in our lives. DAWN will enter orbit around Vesta in late July 2011 bringing us breathtaking images of Vesta.
Saturn's Super Storm
May, 2011 post
"NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope are tracking the growth of a giant early-spring storm in Saturn's northern hemisphere so powerful that it stretches around the entire planet. The rare storm has been wreaking havoc for months and shooting plumes of gas high into the planet's atmosphere...."
This is only the sixth storm to be recorded since 1876, and the last was in 1990.
Oct 2010 - Aug 2012 - A golden age of planetary exploration. To mark an unprecedented flurry of exploration which is about to begin, NASA announced that the coming year (2011) will be "The Year of the Solar System" (YSS).
"During YSS, we'll see triple the [usual] number of launches, flybys and orbital insertions," says Jim Green, Director of Planetary Science at NASA headquarters. "There hasn't been anything quite like it in the history of the Space Age. Naturally, it's a Martian year....

Mars Express and Phobos
To say Phobos, a moon of Mars, is hollow is a bit of an over statement, however it has been concluded by Mars Express that the interior of Phobos likely contains large voids. Mars Express passes by Phobos about every five months providing opportunity for close-up analysis. The next flybys will occur in August 2010 and January 2011. More at the The ESA Mars Express Blog.
