    Oh man, I'd forgotten about that! I just love woo-woo predictions. Has Nancy made any good ones, lately?

    ... and Mars itself is now also within a range of 100 million kilometers from Earth, since 2005-Aug-30 20:40:50 UTC. It will take the red planet another 60.28 days or 58.67 sols to reach its closest position from Earth.

    I'd suggest a MESSENGER countdown thread, but that would last for years and have increasing numbers at times.

    I edited the title so it wasn't misleading. Hope you don't mind.
    Everything I need to know I learned through Googling.

    some MRO news


    Mars missions mapping polar caps, impact craters
    WASHINGTON UNIVERSITY IN ST. LOUIS NEWS RELEASE
    Posted: March 1, 2006
    Two Mars orbiter missions - one from NASA, the other from the European Space Agency (ESA) - will open new vistas in the exploration of Mars through the use of sophisticated ground-penetrating radars, providing international researchers with the first direct clues about the Red Planet's subsurface structure.
    http://www.spaceflightnow.com/news/n0603/01mars/
    Roger Phillips, Ph.D., Washington University in St. Louis Professor of Earth and Planetary Sciences in Arts & Sciences, is participating in both the Mars Express (ESA) and NASA's Mars Reconnaissance Orbiter (MRO) missions by lending his expertise in radar. Phillips says that the combination of the radars on the two missions will provide important and unique data sets that will directly map the structure of the upper portions of the interior of Mars.


    One week from Friday, NASA's Mars Reconnaissance Orbiter (MRO) is expected to begin orbiting the Red Planet, after a seven-month journey from Earth. The probe was launched August 12, 2005.
    http://www.aero-news.net/index.cfm?C...3-2116ae9cbaac
    The $720 million space probe will fire its braking engines for 27 minutes at precisely 4:24 pm MST March 10, beginning its maneuver that, hopefully, will slow the aircraft enough that the planet's gravity will pull it into orbit. Should the engines not fire as designed, the school-bus-sized spacecraft will shoot past Mars, it's mission over.
    "Mars doesn't treat you very well, for the most part," said Doug McCuistion, NASA's Mars exploration program director, to the Rocky Mountain News. "So this is a very challenging thing to do."

    Live coverage of the arrival at Mars originates from NASA's Jet Propulsion Laboratory, Pasadena, Calif., on NASA TV and the Web. The JPL newsroom will be open from 10 a.m. to 10 p.m. EST, March 10. The main number for the newsroom is: (818) 354-5011.


    Live arrival and orbit insertion commentary airs on NASA TV and the Web on March 10 beginning at 3:30 p.m. EST. The orbiter's main engines begin firing shortly after 4:24 p.m. EST to slow it enough for Martian gravity to grab it into orbit. Commentary ends at approximately 5:45 p.m. EST.


    To cover news briefings and mission events at JPL, reporters must contact Media Relations at: (818) 354-5011 not later than 6 p.m. EST, March 7. Valid I.D. and press credentials must be shown on arrival. Non U.S. citizens must present passport and visa. News briefings from JPL will be carried on the Web and NASA TV

    Less than 48 hours to insertion.

    NASA MRO Mission News: Fast-Talking NASA Spacecraft Starts Final Approach to Mars

    The sequence began Tuesday and will culminate with firing the craft's main thrusters for about 27 minutes on Friday -- a foot on the brakes to reduce velocity by about 20 percent as the spacecraft swings around Mars at about 5,000 meters per second (about 11,000 miles per hour). Mission controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Lockheed Martin Space Systems, Denver, are monitoring the events closely.

    "We have been preparing for years for the critical events the spacecraft must execute on Friday," said JPL's Jim Graf, project manager. "By all indications, we're in great shape to succeed, but Mars has taught us never to get overconfident. Two of the last four orbiters NASA sent to Mars did not survive final approach."

    500 thousand kilometers

    Mars Reconnaissance Orbiter was only 500000 kilometers away from Mars at 2006-03-08 22:14:28 UTC.

    The velocity relative to Mars was 2.852 km/s. (13.9x slower than New Horizons relative to Pluto)

    WEDNESDAY, MARCH 8, 2006

    These are tense days at the Jet Propulsion Laboratory and Lockheed Martin spacecraft control centers where engineers are guiding the Mars Reconnaissance Orbiter to Friday's maneuvers for entering orbit around the planet.
    http://www.spaceflightnow.com/mars/mro/status.html
    The 27-minute firing of the six main engines on MRO will slow the craft, allowing Mars to capture the instrument-laden probe into an initial looping orbit. If the burn doesn't occur or gets cut short by a problem, the probe would be doomed to fly right past Mars.

    200 thousand kilometers

    Mars Reconnaissance Orbiter was only 200000 kilometers away from Mars at 2006-03-10 03:18:30 UTC.

    velocity = 2.897 km/s
    range-rate = -2.895 km/s
