NASA Rover Gets Movie As A Mars Moon Passes Another

August 15, 2013 Leave a comment

The larger of the two moons of Mars, Phobos, passes directly in front of the other, Deimos, in a new series of sky-watching images from NASA’s Mars rover Curiosity.

Large craters on Phobos are clearly visible in these images from the surface of Mars. No previous images from missions on the surface caught one moon eclipsing the other.

Large craters on Phobos are clearly visible in these images from the surface of Mars. No previous images from missions on the surface caught one moon eclipsing the other.

These observations of Phobos and Deimos help researchers make knowledge of the moons’ orbits even more precise.

“The ultimate goal is to improve orbit knowledge enough that we can improve the measurement of the tides Phobos raises on the Martian solid surface, giving knowledge of the Martian interior,” said Mark Lemmon of Texas A&M University, College Station. He is a co-investigator for use of Curiosity’s Mastcam. “We may also get data good enough to detect density variations within Phobos and to determine if Deimos’ orbit is systematically changing.”

NASA’s twin lunar Gravity Recovery and Interior Laboratory (GRAIL) spacecraft lifted off from Cape Canaveral Air Force Station in Florida at 9:08 a.m. EDT (6:08 a.m. PDT) Saturday, Sept. 10, to study the moon in unprecedented detail.

GRAIL-A is scheduled to reach the moon on New Year’s Eve 2011, while GRAIL-B will arrive New Year’s Day 2012. The two solar-powered spacecraft will fly in tandem orbits around the moon to measure its gravity field. GRAIL will answer longstanding questions about the moon and give scientists a better understanding of how Earth and other rocky planets in the solar system formed.

Tributes to Terrorism Victims are on Mars

In September 2001, Honeybee Robotics employees in lower Manhattan were building a pair of tools for grinding weathered rinds off rocks on Mars, so that scientific instruments on NASA’s Mars Exploration Rovers Spirit and Opportunity could inspect the rocks’ interiors.

That month’s attack on the twin towers of the World Trade Center, less than a mile away, shook the lives of the employees and millions of others.

Work on the rock abrasion tools needed to meet a tight schedule to allow thorough testing before launch dates governed by the motions of the planets. The people building the tools could not spend much time helping at shelters or in other ways to cope with the life-changing tragedy of Sept. 11. However, they did find a special way to pay tribute to the thousands of victims who perished in the attack.

NASA GRAIL Moon Mission Launch Rescheduled

September 8, 2011 Leave a comment

The launch of a Delta II vehicle carrying NASA’s Gravity Recovery and Interior Laboratory (GRAIL) was scrubbed today, Thursday, Sept. 8, due to weather. Conditions associated with upper level winds were in violation of the launch criteria.

The Delta II and GRAIL are safe and secure at this time. The launch is rescheduled for Friday, Sept. 9, from Space Launch Complex-17B at Cape Canaveral Air Force Station, Fla. There are two instantaneous launch opportunities at 5:33:25 a.m. PDT (8:33:25 a.m. EDT) and 6:12:31 a.m. PDT (9:12:31 a.m. EDT). The forecast for tomorrow (Sept. 9) shows a 40 percent chance of favorable weather conditions for the launch.

Cassini Significant Events 08/24/11 – 08/30/11

September 5, 2011 Leave a comment

The most recent spacecraft telemetry was acquired on August 30 from the Deep Space Network tracking complex at Goldstone, California. The Cassini spacecraft is in an excellent state of health and all subsystems are operating normally. Information on the present position and speed of the Cassini spacecraft may be found on the “Present Position” page at:http://saturn.jpl.nasa.gov/mission/presentposition/.

NASA’s Mars Rover Opportunity Begins Study of Martian Crater

The initial work of NASA’s Mars rover Opportunity at its new location on Mars shows surface compositional differences from anything the robot has studied in its first 7.5 years of exploration.

Opportunity arrived three weeks ago at the rim of a 14-mile-wide (22-kilometer-wide) crater named Endeavour. The first rock it examined is flat-topped and about the size of a footstool. It was apparently excavated by an impact that dug a crater the size of a tennis court into the crater’s rim. The rock was informally named “Tisdale 2.”

Journal Highlights on History of Mars, Dione’s Atmosphere & Saturn’s Aurora

August 31, 2011 Leave a comment

  • New observations from the Compact Reconnaissance Imaging Spectrometer
    for Mars (CRISM) show the presence of multiple magmatic intrusions in
    the Valles Marineris canyon on Mars
  • A new study indicates that one of Saturn’s moons, Dione, probably has
    a tenuous atmosphere.
  • New observations of Saturn’s southern auroral oval made simultaneously
    in ultraviolet (UV) and infrared (IR) wavelengths show how complex and
    dynamic the auroral oval is.
