Planetary Highlights for July
Begin the month by observing Jupiter during the first couple of days of July. Jupiter will disappear by the second week, returning to the morning skies next month. Find Mars in the southwest followed by Saturn. If you can get to a nice dark sky viewing site and a large telescope, Pluto will appear at its best for the year early in the month. Look for Neptune and Uranus in the early morning hours. Venus and Mercury can be spotted before sunrise. The Southern Delta Aquarids meteor shower peaks at the end of the month.
Is stationary on the 1st. Mercury is at greatest western elongation (21° above the eastern horizon) on the 12th. Mercury is visible, low on the eastern horizon about 90 minutes before sunrise for the most part of July. Mercury rises at 4:50 a.m. on the 1st and about 5:17 a.m. by month's end. Mercury moves from the constellation of Taurus into Cancer shining at magnitude 0.0.
Is at aphelion (94.5 million miles from the Sun) on the 3rd.
Sets at 1:08 a.m. on the 1st and about 11:38 p.m. by month's end. Observe Mars with binoculars or a small telescope in the evening skies. Mars is in the constellation of Virgo this month shining at magnitude 0.2.
Is in conjunction with the Sun on the 24th. Jupiter sets at 9:33 p.m. on the 1st. Jupiter rises about 5: 32 a.m. by month's end. Look for Jupiter within a half hour of sunset during the first couple of days of July. Jupiter moves from the constellation of Gemini into Cancer shining at magnitude -1.8.
Is stationary on the 21st. Saturn sets at 2:37 a.m. on the 1st and about 12:34 a.m. by month's end. Look for Saturn in the southwest soon after sunset. View Saturn through a telescope to truly appreciate the planet and its ring system tilted at 21° to our viewing angle. Saturn is in the constellation of Libra shining at magnitude 0.4.
Is stationary on the 22nd. Uranus rises at 1:02 a.m. on the 1st and about 10:56 p.m. by month's end. Look for Uranus in the early morning skies after midnight. Uranus is in the constellation of Pisces shining at magnitude 5.8.
Rises at 11:25 p.m. on the 1st and about 9:22 p.m. by month's end. Look for Neptune in the late evening and early morning skies. Neptune is in the constellation of Aquarius shining at magnitude 7.8.
Sets at 2:51 a.m. on the 1st and about 12:54 a.m. by month's end. Ceres and Vesta, the two brightest asteroids, travel the closest they have ever been since their discovery. During the first week of July, the pair close from 19 minutes of arc to within 10 minutes of arc (1/3 the size of the full moon). On the evenings of the 4th and 5th, both Ceres and Vesta can be spotted within the same field of view in a telescope. Ceres is in the constellation of Virgo shining at magnitude 8.4, Vesta shines at magnitude 7.1 (about 3 times brighter than Ceres).
Reaches opposition on the morning of the 4th. Pluto is at its best visibility this month. Pluto rises at 8:19 p.m. on the 1st and about 6:15 p.m. by month's end. Pluto is in the constellation of Sagittarius shining at magnitude 14.1.
As always, good luck at spotting Neptune, Ceres and Pluto, a large telescope and dark skies will be needed.

|New Horizons - June 23, 2014
The PI's Perspective
"As I mentioned in my previous PI Perspective, New Horizons crosses the orbit of Neptune, the outermost planet explored by the Voyager mission, late this August. Voyager's flyby of Neptune was in August 1989, 25 years ago!
Across flights launched in 1977 and spanning the entirety of the 1980s, Voyagers 1 and 2 performed the historic, first detailed reconnaissance of our solar system's four giant planets (Jupiter, Saturn, Neptune, Uranus). The essentially identical Voyagers were launched with a core mission to explore the Jupiter and Saturn systems, and each spacecraft carried a powerful and diverse scientific instrument suite. After Saturn, Voyager 2 was tasked with reconnoitering Uranus and Neptune during an extended mission.
Although Pluto's orbital position relative to Neptune made it impossible for Voyager 2 to travel to it from Neptune, Voyager 1 actually could have reached Pluto after its Saturn flyby, had it been targeted to do so. In fact, NASA and the Voyager project actually considered this option, but eliminated it in 1980 -- going instead with the very exiting but lower-risk opportunity to investigate Saturn's large, scientifically enticing, cloud-enshrouded and liquid-bearing moon Titan.
But if Voyager 1 had been sent to Pluto, it would have arrived in the spring of 1986, just after Voyager 2's exploration of Uranus that January. As New Horizons approaches Pluto in 2015, it's fun to think what we might have found almost 30 years ago had Voyager 1 - rather than New Horizons - been first to Pluto."

NASA Helps 'Angry Birds Space' Find Asteroids Deeper in Space
"After a couple of years and hundreds of millions of downloads, the space-based struggle between birds and pigs moves beyond the International Space Station and Mars, and deeper into the final frontier. The latest update from Rovio Entertainment sends Angry Birds Space into NASA's next target for future human exploration - asteroids!
"Beak Impact" takes flight Thursday. It is a new astronomical struggle that blends the excitement of the world's most popular mobile gaming application with the science, technology, and information surrounding the agency's future missions into deep space.
"The collaboration with Rovio and Angry Birds Space is an extraordinary opportunity to reach millions of gamers and use the fictional universe to point players to real information about asteroids, why NASA studies them and how they fit into our exploration path to Mars," said David Weaver, associate administrator for the Office of Communications at Headquarters in Washington. "It is a great opportunity to educate, inform, and even inspire players about space exploration, all while playing one of the most popular interactive games ever created."
The agency has embarked on an important mission to detect, track, and characterize potentially hazardous asteroids that could threaten our home planet. And a part of NASA's effort to send humans to Mars is to capture and explore an asteroid. Hidden in the various levels of "Beak Impact" are direct links to NASA information about the spacecraft and missions that will tell us more about these celestial bodies."

MESSENGER Modifies Orbit to Prepare for Low-Altitude Campaign
"MESSENGER successfully completed the first orbit-correction maneuver of its Second Extended Mission this morning to raise its minimum altitude above Mercury from 113.9 kilometers (70.8 miles) to 155.1 kilometers (96.4 miles). This maneuver is the first of four designed to modify the spacecraft's orbit around Mercury so as to delay the spacecraft's inevitable impact onto Mercury's surface and allow scientists to continue to gather novel information about the innermost planet.
During the primary phase of the MESSENGER mission, the spacecraft's orbit around Mercury was highly eccentric, drifting between 200 and 500 kilometers (124 to 311 miles) above Mercury's surface at closest approach, and between 15,200 and 14,900 kilometers (9,445 to 9,258 miles) above the surface at its farthest point, and completing an orbit every 12 hours. Spacecraft operators at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, conducted several spacecraft maneuvers to counter the perturbing forces that caused MESSENGER's lowest orbital altitude to drift upward, away from its preferred observing geometry, and early in MESSENGER's First Extended Mission conducted a pair of maneuvers to reduce the orbital period to eight hours.
"In this final phase of the mission, the opposite effect is happening," explained the mission trajectory lead Jim McAdams of APL. "To extend the mission, we need to raise the minimum altitude by increasing the Mercury-relative speed of the spacecraft when it is farthest from Mercury."
For this latest orbit adjustment, MESSENGER was 82.9 million kilometers (51.5 million miles) from Earth and 69.8 million kilometers (43.3 million miles) from the Sun. The 3.2-minute-long maneuver -- which used two of the four largest monopropellant thrusters, with a small contribution from four of the 12 smallest monopropellant thrusters -- began at about 10:53 a.m., EDT. APL mission controllers verified the start of the maneuver 4.6 minutes later, when the first signals indicating spacecraft thruster activity reached MESSENGER's Mission Operations Center via NASA's Deep Space Network tracking station outside of Madrid, Spain."

NASA's Curiosity Rover Team Today Features Women
Women of Mars, in Mars Yard at JPL
"NASA's Curiosity Mars rover this week completed its first Martian year -- 687 Earth days -- since landing in August 2012. Each day of the rover working on Mars requires several dozen rover team members completing tasks on Earth. To celebrate reaching this longevity milestone, which had been set as one of the mission's goals from the start, the Curiosity team planned staffing a special day, with women fulfilling 76 out of 102 operational roles.
"I see this as a chance to illustrate to girls and young women that there's not just a place for them in technical fields, but a wide range of jobs and disciplines that are part of the team needed for a project as exciting as a rover on Mars," said Colette Lohr, an engineer at NASA's Jet Propulsion Laboratory, Pasadena, California.
"There's no practical way any one person could learn all the disciplines needed for operating Curiosity," she said. "It takes a team and we rely on each other."
Disciplines range from soil science to software engineering, from chemistry to cartography, in duties ranging from assessing rover-temperature data freshly arriving from Mars to choosing where to point the rover's cameras. Descriptions of the roles, along with names and locations of the team members filling them today, are part of Curiosity Women's Day information available at: http://go.usa.gov/9d3x"

|Mars Exploration Rover Mission (Spirit and Opportunity) - June 24, 2014
SPIRIT UPDATE: Spirit Remains Silent at Troy - sols 2621-2627, May 18-24, 2011:
More than 1,300 commands were radiated to Spirit as part of the recovery effort in an attempt to elicit a response from the rover. No communication has been received from Spirit since Sol 2210 (March 22, 2010). The project concluded the Spirit recovery efforts on May 25, 2011. The remaining, pre-sequenced ultra-high frequency (UHF) relay passes scheduled for Spirit on board the Odyssey orbiter will complete on June 8, 2011.
Total odometry is unchanged at 7,730.50 meters (4.80 miles)."
OPPORTUNITY UPDATE: Rover Has Enough Energy for Some Late-Night Work - sols 3697-3703, June 18, 2014-June 24, 2014 :
"Opportunity is exploring the west rim of Endeavour Crater. The rover is continuing south along the ridgeline that forms the spine of the crater rim, collecting color imagery of targets and outcrops along the way.
With ample energy, Opportunity has been able to conduct some late-night activities. On Sol 3697 (June 18, 2014), the rover collected an atmospheric argon measurement with the Alpha Particle X-ray Spectrometer (APXS), and took advantage of a Phobos moon imaging opportunity. On Sol 3698 (June 19, 2014), the rover proceeded just over 82 feet (25 meters) to the south with another Phobos imagining opportunity that night, and an argon measurement on the next night. Sol 3700 (June 21, 2014), was the first sol of a 2-sol 'touch 'n go' with the collection of a Microscopic Imager (MI) mosaic and subsequent APXS measurement on a surface target of opportunity. The rover then drove on the next sol, heading 42 feet (13.5) meters south.
On Sol 3703 (June 24, 2014), Opportunity began an approach to a surface target with a 31 feet (9.4-meter) move. Also, the project continues with the spacecraft clock correction, moving the clock about 3 seconds back each sol. There have been no Flash-related anomalies and the rover continues in good health.
As of Sol 3703 (June 24, 2014), the solar array energy production was 743 watt-hours with an atmospheric opacity (Tau) of 0.652 and a solar array dust factor of 0.894.
Total odometry is 24.60 miles (39.59 kilometers)."

|Mars Reconnaissance Orbiter Mission - May 22, 2014
NASA Mars Weather Camera Helps Find New Crater on Red Planet
"Researchers have discovered on the Red Planet the largest fresh meteor-impact crater ever firmly documented with before-and-after images. The images were captured by NASA's Mars Reconnaissance Orbiter (MRO).
The crater spans half the length of a football field and first appeared in March 2012. The impact that created it likely was preceded by an explosion in the Martian sky caused by intense friction between an incoming asteroid and the planet's atmosphere. This series of events can be likened to the meteor blast that shattered windows in Chelyabinsk, Russia, last year. The air burst and ground impact darkened an area of the Martian surface about 5 miles (8 kilometers) across."
