The Planets & Dwarf Planets
Planetary Reports generated by "TheSky" software. 
(http://www.ki0ar.com/planrpts.html ) These reports provide predicted data for 
the planets for the first of each month for the current year. The rise and set 
times for the Sun and the Moon for each day of the month are also included in 
the reports.
(All times are local unless otherwise noted.)

* Planetary Highlights for March - Venus disappears from the evening sky late 
in the month. Mercury also disappears from the morning sky late in the month. 
Saturn reaches opposition and greatest brightness for the year. Neptune joins 
Jupiter, Mercury and Mars in the pre-dawn sky. Dwarf planet Ceres is as close 
as it has been to Earth since 1857 and won't be this close again for more that 
1,000 years. Earth also reaches equinox.

* Mercury - Is in superior conjunction on the 30th. Look for Mercury during the 
first and second weeks of March. Mercury rises at 5:44 a.m. on the 1st and 
about 5:52 a.m. by month's end. Mercury moves from the constellation of 
Capricornus through Aquarius into Pisces this month shining at magnitude -0.1.

* Venus - Is in inferior conjunction on the 27th. Venus appears to descent 
rapidly towards the western horizon in the next couple of weeks. Catch a 
glimpse of Venus during the first two weeks of March. Venus is in the 
constellation of Pisces this month. Venus sets at 8:47 p.m. on the 1st and 
about 5:52 p.m. by month's end. Venus shines at magnitude -4.8.

* Earth - The Vernal equinox occurs at 7:44 a.m. EDT.

* Mars - Rises at 5:42 a.m. on the 1st and about 4:43 a.m. by month's end. Mars 
remains difficult to spot through the morning twilight before sunrise. Mars 
views will improve as the year progresses. Look for Mars very low in the east 
before sunrise. Mars moves from the constellation of Capricornus into Aquarius 
this month shining at magnitude 1.2.

* Jupiter - Rises at 5:21 a.m. on the 1st and about 3:38 a.m. by month's end. 
Jupiter continues to climb higher in the morning sky as the month progresses. 
Jupiter is in the constellation of Capricornus shining at magnitude -2.0.

* Saturn - Is at opposition on the 8th rising as the Sun sets reaching peak 
visibility on this date as well. Rises at 6:18 p.m. on the 1st and about 4:04 
p.m. by month's end. Saturn is visible all evening this month. Saturn is in the 
constellation of Leo shining at magnitude 0.5.

* Uranus - Is in conjunction with the Sun on the 12th. Uranus is not visible 
this month.

* Neptune - Has returned to the morning sky along with Mercury, Mars and 
Jupiter. Neptune rises at 5:53 a.m. on the 1t and about 3:54 a.m. by month's 
end. Neptune is in the constellation of Capricornus shining at magnitude 8.0.

Dwarf Planets  
* Ceres - Rises at 4:46 p.m. on the 1st and about 3:22 p.m. by month’s end. 
Ceres is in the constellation of Leo shining at magnitude 6.9.

* Pluto - Rises at 2:33 a.m. on the 1st and about 12:32 a.m. by month's end. 
Pluto is in the constellation of Sagittarius shining at magnitude 14.0.

Good luck at spotting these two, a large telescope and dark skies will be 
needed.

-----------------------------------------------------------

Astronomical Events

Meteor Showers
* There are some minor meteor showers this month but none that produce rates 
much higher than 2-5 per hour, except the Gamma Normids that extend over the 
period of March 11 to 21, with the maximum occurring on March 16. The maximum 
rate reaches about 5-9 meteors per hour.

* For more information about Meteor Showers, visit Gary Kronk's Meteor Showers 
Online web page at http://meteorshowersonline.com/.

Comets
* Say goodbye to Comet Lulin which begins to dim as it moves away from Earth 
this month. Comet Lulin is around 7th magnitude at the beginning of the month 
but dims to 9th magnitude by month's end. Look for Lulin to pass within 2° of 
the Beehive cluster (M44) on the 5th and to pass within 0.25° of the Eskimo 
Nebula on the 14th. This comet should be easily spotted with a good pair of 
binoculars or a small telescope even from urban skies.

Planetary/Lunar Exploration Missions
(Excerpts from recent mission updates)

* Cassini - February 26, 2009
Seasons Changing on Saturn

"Todd J. Barber, Cassini lead propulsion engineer - 
February may be a short month, but it was long on Cassini science observations 
at Saturn, even during the first week! 

For starters, just as Punxsy Phil was emerging from his hollow stump in western 
Pennsylvania on Groundhog Day, Cassini was observing light and shadows as well 
on the intriguing moon Rhea during a non-targeted flyby. I'm sure the entire 
flight team is excited for our close Rhea encounter next year, particularly 
since this icy satellite of Saturn humbled us with the perplexing discovery of 
a potential ring system, the first ever seen around a moon. Until next year, 
though, these more distant encounters will have to suffice, whetting our 
voracious and bottomless scientific appetites. Also, unlike Punxsy Phil's 
checkered history in prognosticating six more weeks of winter, Cassini can 
confidently state that seasons are changing on Saturn. The north polar region 
will soon see the sun for the first time in nearly fifteen years, and another 
harbinger of seasonal change - ring spokes - should start becoming more 
prevalent as well. Spokes in Saturn's rings were
 one of the most captivating discoveries from Voyager, so we are only too happy 
to continue observing these beautiful, transient features with Cassini."

* New Horizons - No new news since January 19, 2009
Launch Plus Three Years: Looking Back, Looking Ahead

On the anniversary of New Horizons’ launch from Cape Canaveral Air Force 
Station, Fla., on January 19, 2006, mission team members reflect on liftoff, a 
busy first three years of flight and the ongoing voyage to Pluto and beyond.

Countdown to Liftoff

"To Ralph McNutt, of the Johns Hopkins Applied Physics Laboratory (APL), launch 
wasn’t just a beginning – it was the culmination of a hard-fought, nearly 
two-decade-long battle in the scientific community to secure a mission to the 
ninth planet.

"When the announcer hit 'zero' and the Atlas V rocket began plowing its way 
through the wispy skin of this pale blue dot we call home, it was a special 
moment," says McNutt, principal investigator of the New Horizons Pluto 
Energetic Particle Spectrometer Science Investigation, or PEPSSI. "We really 
were on the way, and no one could stop us from taking that path to new lands."

Science team co-investigator Richard Binzel of the Massachusetts Institute of 
Technology remembers the run-up to launch, a four-year concert of spacecraft 
design, build and testing, and mission planning that had to reach its crescendo 
by January 2006, in time to meet a month-long launch period and take advantage 
of an opportunity to use Jupiter's gravity as a slingshot toward deeper space. 
 
"The transition from launch to flight is truly phenomenal," Binzel says. 
“Before launch, the clock looms so large.  Everything has to be ready at the 
launch window, or else!  In cruise phase the pace of hard work continues, but 
now the responsibility feels different. We know New Horizons will reach Pluto!"

* Dawn - February 26, 2009
Dawn Finishes Mars Phase

Mission Status Report: NASA's Dawn Mission

"With Mars disappearing in its metaphorical rearview mirror, NASA's Dawn 
spacecraft's next stop is the asteroid belt and the giant asteroid Vesta. Dawn 
got as close as 549 kilometers (341 miles) to the Red Planet during its 
Tuesday, Feb. 17, flyby. 

Dawn's navigators placed the spacecraft on a close approach trajectory with 
Mars so the planet's gravitational influence would provide a kick to the 
spacecraft's velocity. If Dawn had to perform these orbital adjustments on its 
own, with no Mars gravitational deflection, the spacecraft would have had to 
fire up its engines and change velocity by more than 9,330 kilometers per hour 
(5,800 miles per hour). 

The achieved goal of the flyby was to obtain this orbital pick-me-up, making 
possible its voyage to asteroid Vesta and, later, the dwarf planet Ceres. But 
Dawn's science teams used this massive target of opportunity to also perform 
calibrations of some of the scientific instruments. Calibration images were 
taken by Dawn's framing camera, and the Gamma Ray and Neutron Detector also 
observed Mars for calibration. These data will be compared to similar 
observations taken by spacecraft orbiting Mars."

* MESSENGER - February 9, 2009
MESSENGER Continues Hunt for Ever-Elusive Vulcanoids

"MESSENGER reaches its orbital perihelion today and passes within 0.31 
astronomical units (AU) of the Sun (one AU is nearly 150 million kilometers or 
93 million miles). The mission’s imaging team is taking advantage of the 
probe’s proximity to the fiery sphere to continue their search for vulcanoids - 
small, rocky asteroids that have been postulated to circle the Sun in stable 
orbits inside the orbit of Mercury. 

Vulcanoids are named after Vulcan, a planet once proposed to explain unusual 
motions in Mercury’s orbit. Scientists have long suspected that these small, 
faint “space rocks” exist. There is a gravitationally stable region between the 
orbit of Mercury and the Sun, which means that any objects that originally 
formed there could have remained for billions of years and might still be there 
today. All other such regions in the solar system are occupied by some type of 
debris (e.g., Trojan asteroids at stable points along the orbits of Jupiter and 
Neptune and Kuiper Belt objects near and beyond the orbit of Pluto).

The so-called vulcanoid region between the orbit of Mercury and the Sun is the 
main gravitationally stable region that is not known to be occupied. The region 
is, however, the most difficult to observe. Any vulcanoids would be difficult 
to detect from Earth because of the strong glare of the Sun. Previous vulcanoid 
searches have revealed no bodies larger than 60 kilometers in diameter. But 
MESSENGER’s travels in near-Mercury space enable a search for vulcanoids from a 
vantage never before attempted, says MESSENGER Science Team Member Clark 
Chapman, who is spearheading the team’s search along with his associate, 
William Merline."

Mars Missions

* Mars Odyssey Orbiter - No new news since November 17, 2008
Gamma-Ray Evidence Suggests Ancient Mars Had Oceans

"An international team of scientists who analyzed data from the Gamma Ray 
Spectrometer onboard NASA's Mars Odyssey reports new evidence for the 
controversial idea that oceans once covered about a third of ancient Mars.

"We compared Gamma Ray Spectrometer data on potassium, thorium and iron above 
and below a shoreline believed to mark an ancient ocean that covered a third of 
Mars' surface, and an inner shoreline believed to mark a younger, smaller 
ocean," said University of Arizona planetary geologist James M. Dohm, who led 
the international investigation.

"Our investigation posed the question, Might we see a greater concentration of 
these elements within the ancient shorelines because water and rock containing 
the elements moved from the highlands to the lowlands, where they eventually 
ponded as large water bodies?" Dohm said."

"A simulated fly-through using the newly assembled imagery is available online 
at http://www.nasa.gov/mission_pages/mars/missions/odyssey/20060313.html.

* Mars Exploration Rover Mission (Spirit and Opportunity) -

SPIRIT UPDATE:  Another Cleaning - sol 1817-1823, February 11-17, 2009:

Spirit has been continuing attempts to reach an on-ramp for ascending onto 
"Home Plate." The terrain continues to be difficult for driving with five 
wheels. Because of limited progress on previous sols, on Sol 1818 (February 12, 
2009), Spirit attempted a series of sharp backward arcs. Spirit executed 
60-centimeter (2-foot) arcs 29 times, but, due to wheel slippage, the rover 
made only 17 centimeters (7 inches) of progress.

On Sol 1820 (February 14, 2009), the plan was to drive forward, away from Home 
Plate, and turn. The rover was successful in turning about 45 degrees, 
sufficient to get the wheels out of the soft terrain where they had been 
digging in. Spirit will next attempt the approach to Home Plate while avoiding 
some of the soft terrain that complicated previous approaches.

The team continues to track the performance of the rover's accelerometers.

Another small dust-cleaning event on Sol 1820 (February 14, 2009) -- the second 
one this month -- improved solar-array performance by an additional 10 percent.

As of Sol 1823 (February 17, 2009) Spirit's solar-array energy production 
improved to 275 watt-hours. Atmospheric opacity (tau) increased slightly to 
0.530. The dust factor is 0.306, meaning that 30.2 percent of the sunlight 
hitting the solar array penetrates the layer of accumulated dust on the array. 
The rover is in good health.

Spirit's total odometry as of Sol 1822 (February 16, 2009) is 7,572.23 meters 
(4.71 miles)


OPPORTUNITY UPDATE:  Checking the Right-Front Wheel - sol 1797-1802, February 
12-17, 2009:

Opportunity is continuing with a series of long drives. The drive on Sol 1797 
(February 12, 2009) achieved 111 meters (364 feet). During the drive the 
right-front wheel exhibited higher-than-usual motor currents. Since April 2005, 
Opportunity's right-front wheel has had a jammed steering actuator, with the 
wheel turned inwards about 7 degrees from straight ahead, so it works harder on 
some drives. On Sol 1800 (February 15, 2009), the rover conducted a series of 
mobility diagnostic drives to study the right-front wheel. The rover turned 
around and drove backward about 10 meters (31 feet), turned around again and 
drove forward about 11 meters (36 feet), and then performed an arc of about 4 
meters (13 feet). The wheel currents were monitored.

The plan for the near term is to drive backward to see if that improves 
performance of the right-front wheel, although backward driving will limit the 
distance traveled each sol.

As of Sol 1802 (February 17, 2009), Opportunity's solar-array energy production 
is 567 watt-hours. Atmospheric opacity (tau) has moderated to 0.540. The dust 
factor on the solar array is 0.589, meaning that 58.9 percent of the sunlight 
hitting the solar array penetrates the layer of accumulated dust on the array. 
The rover is in good health.

Opportunity's total odometry as of Sol 1801 (February 16, 2009) is 14,621.57 
meters (9.09 miles)."

* Mars Reconnaissance Orbiter Mission - February 25, 2009
Fractured Lavas Suggest Floods on Mars

"Images from NASA's Mars Reconnaissance Orbiter show a type of rock fracturing 
that here on Earth is caused by rapid cooling of lava. 

Unique fractures in lavas on ancient Mars suggest water occasionally flooded 
portions of the planet's surface.

The fractures, known as "columnar joints", are the first that have been 
observed on a planet other than Earth. "Columnar joints form as cooling lava 
contracts," explains Moses Milazzo, a geophysicist with the U.S. Geological 
Survey in Flagstaff. The characteristics of the column-like fractures can help 
scientists understand the role of water in geologic processes on Mars. Milazzo, 
working with the NASA Mars Reconnaissance Orbiter HiRISE camera team, recently 
published their discovery in the journal Geology.

The columns, a meter in diameter and about 30 meters high, were identified in 
the tilted inner walls of an impact crater. "The HiRISE instrument just barely 
has the resolution to pick out the columns if they're facing the camera with 
the perfect orientation," said Milazzo. When the impact crater formed, the 
rocks were tilted backward, toward the sky. This tilting of the columns toward 
the sky is what allowed the identification."

* Phoenix Mars Lander Mission - February 19, 2009
Award to Recognize Phoenix Mars Lander Team

"The team that developed and operated NASA's Phoenix Mars Lander mission will 
receive the 2009 John L. "Jack" Swigert Award for Space Exploration from the 
Space Foundation. 

During five months of operations at a Martian arctic site after landing on May 
25, 2008, the Phoenix spacecraft confirmed the presence of frozen water just 
below the surface, identified potential nutrients and other substances in the 
soil, and observed snow in the atmosphere. 

The Space Foundation, based in Colorado Springs, Colo., announced Feb. 19 
[http://www.spacefoundation.org/news/story.php?id=658] that it will present the 
award to the Phoenix team on March 30, during the foundation's 25th National 
Space Symposium, in Colorado Springs."
