NASA Briefings and TV Coverage Schedule for Phoenix Mars Landing
PASADENA, Calif. -- NASA news briefings, live commentary and updates before and after the
scheduled Sunday, May 25 arrival of the agency's Phoenix Mars Lander will be available on NASA
Television and on the Web.
Entry, descent and landing begins at 4:46 p.m. PDT on May 25, when the flight team listens for
radio signals indicating that Phoenix has entered the top of the Martian atmosphere. The spacecraft
must perform a series of challenging transformations and activities during the seven minutes after it
enters the atmosphere to slow it from 12,000 mph to 5 mph and a soft touchdown. The Phoenix team
will be watching for radio signals confirming the landing at 4:53 p.m. More than half of previous
international attempts to land on Mars have been unsuccessful. For a detailed schedule and landing
timeline, visit:
The deadline for U.S. journalists to request media credentials to cover the Phoenix mission from
NASA's Jet Propulsion Laboratory in Pasadena, Calif., is Tuesday, May 20. Foreign journalists
requesting credentials must apply by Friday, May 16. Requests for media credentials must be made
online at:
https://eis.jpl.nasa.gov/media/index.html
Media wishing to cover the mission from the University of Arizona in Tucson, must apply online at:
Briefings on mission goals, challenges, status and final trajectory adjustments will originate from
JPL on Thursday, May 22, at 11:30 a.m. and on Saturday and Sunday, May 25-26, at noon.
On landing day, May 25, live landing commentary will air on NASA TV. A telecast of mission
control -- without roll-in videos and interviews -- will run on NASA TV's Media Channel beginning
at 3 p.m. Another telecast with commentary, interviews and videos will begin at 3:30 p.m. on NASA
TV's Public Channel. For more information on NASA TV and this coverage schedule, visit:
http://www.nasa.gov/multimedia/nasatv/MM_NTV_Breaking.html
Both telecasts will continue through landing and will resume at 6:30 p.m. during the period after
landing when engineers anticipate the receipt of data and possible images confirming that Phoenix
has opened its solar panels successfully.
A news briefing at JPL will be held Sunday, May 25 at 9 p.m., following landing and the first
possible downlink of images. Briefing updates at JPL also are scheduled on Monday, May 26 at 11
a.m. and on Tuesday, May 27 at 11 a.m.
Daily news briefings will continue at 11 a.m. for several days following a successful landing.
Mission control and the site for news briefings will then shift to the University of Arizona in Tucson
after a determination that the spacecraft is in a safe condition for conducting science operations. The
earliest possibility for moving the host site for mission news briefings to the University of Arizona's
Space Operations Center is Wednesday, May 28. Mission briefings from Pasadena and Tucson will
be carried on NASA TV unless preempted by other NASA events.
