Launched in August 2007, the Phoenix Mars Mission is the first in NASA's Scout Program. Phoenix is designed to study the history of water and habitability potential in the Martian arctic's ice-rich soil.
The Phoenix Mars Mission has a collaborative approach to space
exploration. As the very first of NASA's Mars Scout class, Phoenix
combines legacy and innovation in a framework of a true partnership:
government, academia, and industry. Scout class missions are led by a
scientist, known as a Principal Investigator (PI). Peter Smith of the University of Arizona's Lunar and Planetary Laboratory serves as Phoenix's PI and is responsible for all aspects of the mission.
The Phoenix Mission has a three-vertebrae backbone: the PI at the University of Arizona, the project manager at the Jet Propulsion Laboratory (JPL), and the flight system manager at Lockheed Martin Space Systems (LMSS). These three frequently communicate and ensure that decisions are understood and quickly implemented by the team.
PI Smith has delegated project management responsibility to JPL. Barry Goldstein
serves as the project manager and leads an experienced team of JPL
engineers and scientists. Under Goldstein, the JPL team conducts vital
functions of payload management, and flight systems and mission
operations. These functions are supported by system engineering, mission
assurance, and a business office. JPL also provides the interface to
the Deep Space Network,
sending command sequences and receiving data. During the 10-month
cruise phase to Mars, JPL maintains the proper cruise trajectory to get
the spacecraft to Mars by performing correcting maneuvers. Finally, JPL
will lead the Phoenix spacecraft through the highly risky
entry-descent-landing process. No team surpasses JPL in its ability to
land spacecraft safely on the Martian surface.
Ed Sedivy
leads the Lockheed Martin engineering team in designing, constructing,
and testing the Phoenix spacecraft. Sedivy was Lockheed Martin's chief
engineer for developing the Mars Surveyor 2001 lander,
the highly capable spacecraft that the Phoenix Mission is inheriting.
The Lockheed Martin engineering team is restoring the 2001 lander to a
flight-ready Phoenix spacecraft and developing enhanced spacecraft
reliability through extensive testing. Throughout all phases of the
mission, the Lockheed Martin team will closely monitor Phoenix's health
by linking their spacecraft operations centers with those at JPL and the
University of Arizona.
From the University of Arizona, PI Smith works closely with Leslie Tamppari,
project scientist at JPL, to lead an international assembly of
scientists from a wide variety of academic, private, and government
research institutions. This science team
has experience in all previous landed Mars missions. The team's
scientific background includes experience in hydrology, geology,
chemistry, biology, and atmospheric science. For operations, the team is
conceptually divided into four instrument groupings, each with a lead
co-investigator (Co-I) scientist. The groups are not intended to be
restrictive: Co-Is are expected to have a broad, cross-instrument
participation driven by scientific objectives. The science team will
co-locate for the first three months of the mission, to operate all the
instruments and to perform the first analysis on data that may provide
important answers to the following questions:
(1)
can the Martian arctic support life,
(2) what is the history of water
at the landing site, and
(3) how is the Martian climate affected by
polar dynamics?
To answer these questions, Phoenix uses some of the most
sophisticated and advanced technology ever sent to Mars. A robust
robotic arm built by JPL digs through the soil to the water ice layer
underneath, and delivers soil and ice samples to the mission's
experiments. On the deck, miniature ovens and a mass spectrometer, built by the University of Arizona and University of Texas-Dallas, will provide chemical analysis of trace matter. A chemistry lab-in-a-box, assembled by JPL, will characterize the soil and ice chemistry. Imaging systems, designed by the University of Arizona, University of Neuchatel (Switzerland) (providing an atomic force microscope), Max Planck Institute (Germany) and Malin Space Science Systems, will provide an unprecedented view of Mars—spanning 12 powers of 10 in scale. The Canadian Space Agency will deliver a meteorological station, marking the first significant involvement of Canada in a mission to Mars.
The University of Arizona will also host the Phoenix Mission's
Science Operations Center (SOC) in its Tucson facility. From the SOC,
the Phoenix science and engineering teams will command the lander once
it is safely landed on Mars, and also, receive data as it is transmitted
directly to Earth. A payload interoperability test bed (PIT) will be
located with the SOC to verify an optimal integration of Phoenix's
complex scientific instruments. Working together, the SOC and PIT will
ensure a seamless scientific and engineering process—from science goal
to instrument commands to down-linked and analyzed data.
As with all major NASA missions, Phoenix has a comprehensive education and public outreach program.
PI Smith leads the program, which is managed by the University of
Arizona, and connects to outstanding educational resources in the desert
southwest region, and throughout the U.S.
This powerful team is the cornerstone to the Phoenix mission, which
has high hopes to be the first mission to "touch" and examine water on
Mars—ultimately, to pave the way for future robotic missions, and
possibly, human exploration.
Dust Storm Moving Near Phoenix Lander
This series of images show the movement of several dust storms near
NASA's Phoenix Mars Lander. These images were taken by the lander's
Surface Stereo Imager (SSI) on the 137th Martian day, or sol, of the
mission (Oct. 13, 2008).
These images were taken about 50 seconds apart, showing the formation
and movement of dust storms for nearly an hour. Phoenix scientists are
still figuring out the exact distances these dust storms occurred from
the lander, but they estimate them to be about 1 to 2 kilometers (.6 or
1.2 miles) away.
