Phoenix Flying True Enough to Skip One Scheduled Adjustment
May 09, 2008

NASA's Phoenix Mars Lander continues on course for its May 25 arrival at Mars. After targeting its certified landing site with a trajectory, or flight path, correction maneuver on April 10, the spacecraft's performance has been stable enough for the mission's operators to forgo the scheduled opportunity for an additional trajectory correction maneuver on May 10 and focus on the next such opportunity, on May 17.

The Phoenix navigation team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., made that recommendation after assessing the trajectory this week and mission management accepted the recommendation late Thursday. Phoenix has performed three flight path correction maneuvers since its Aug. 4, 2007, launch. Besides the May 17 one, the final opportunity for adjusting the course to hit the targeted landing area will be in the final 24 hours before landing.

The first possible confirmation time for the spacecraft's landing on May 25 will be at 4:53 p.m. Pacific Daylight Time. The event would have happened 15 minutes and 20 seconds earlier on Mars, and then radio signals traveling at the speed of light will take 15 minutes and 20 seconds to cross the distance from Mars to Earth on that day.

The Phoenix mission is led by Peter Smith of the University of Arizona, Tucson, with project management at JPL and development partnership at Lockheed Martin, Denver. International contributions are provided by the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; the Max Planck Institute, Germany; and the Finnish Meteorological Institute.
