Module 1 - Mission to Planet Earth
A) What is Mission to Planet Earth?
Objectives
- Students will understand the goals of Mission to Planet Earth
(to study Earth as a system, including interactions between
Atmosphere, Ocean and Land)
- Students will summarize at least two global issues addressed
by Mission to Planet Earth
- Students will be introduced to the idea of using different instruments
and technologies to observe the Earth
In response to concerns about the earth's environment, the National
Aeronautics and Space Administration is initiating a program to study the earth
as a system. This program is called Mission to Planet Earth (MTPE).
NASA's Mission to Planet Earth will study how the global environment is
changing. Using the unique perspective available from space, NASA will observe,
monitor and assess large-scale environmental processes, focusing on climate
change. MTPE satellite data, complemented by aircraft and data, will allow us
to better understand natural environmental changes from human-induced changes.
MTPE data, which NASA will distribute to researchers worldwide, is essential to
humans making informed decisions about protecting their environment.
Science Themes
The following are the underlying science themes for MTPE:
- Environmental processes are global in scale, complex and closely
connected.
- Each component of the environment -- air, water, land, biota -- is
continually changing, and changes in one component affect the other.
- Changes can occur naturally or as a result of human activities. These
changes occur on such a scale that they require long-term observation and
analysis.
- These closely connected systems require interdisciplinary research.
- MTPE will provide that long-term, interdisciplinary research.
Program Themes
- NASA conceived and initiated MTPE because the unique global perspective
available from space allows comprehensive, long-term measurements of
environmental processes.
- NASA's MTPE space-based remote-sensing programs are complemented and
verified by aircraft, balloon and ground-based measurements.
- NASA's MTPE programs are distributed across the United States through NASA
centers, universities and other institutions. MTPE is a cooperative program
within the U.S. Global Change Research Program, which involves other federal
agencies with different areas of environmental expertise.
- NASA's MTPE is an international program, involving other countries in an
attempt to solve problems that recognize no national boundaries.
- NASA's MTPE focus is information -- providing the data policy makers and
nations need to make informed decisions about the global environment.
As part of NASA's Mission to Planet Earth, JPL is investigating the
biological, chemical and physical features of Earth's atmosphere, oceans, land
surface and crust - and studying aspects of the interfaces between them. To
address key global problems such as ozone depletion, climate change, volcanism
and tectonism, JPL scientists acquire data from remote-sensing instruments
carried by aircraft, balloons and satellites; insights are also gained through
laboratory experimentation, field work and theoretical modeling. While research
is becoming largely interdisciplinary in nature, JPL is building on strengths
in traditional areas of expertise, such as atmospheric chemistry, oceanography,
geology and geodynamics.
