New Budget Initiatives for NASA in FY04
3
Aerosols provide the largest uncertainty in the
determination of the Climate Forcing Function
FY04 Presidents budget calls for accelerated
development and launch of an advanced
polarimeter to increase our understanding of
black carbon soot and other aerosols as causes of
climate change .

• Science objectives of the CCRI APS (CAPS)
• Determine the global distribution of natural and
  anthropogenic aerosols with accuracy and coverage
  sufficient for a reliable quantification of the
  aerosol effect on climate.
• Measurement approach
• Retrieval of aerosol particle microphysical
  properties by inverting radiance and polarization
  measurements.
• The CAPS polarimeter weighs approximately 25 kg
  and uses approximately 25 watts of power, while
  being 10 times more accurate than present
  instruments.

Building Blocks Enable New Capabilities

• Optical Communications

• Using laser light instead of radio waveswill
  dramatically increase our ability to transmit
  information across the solar system
• First demonstration from Mars
• Earth-based terminals
• Space or airborne or ground
• 24/7 coverage

Completing Einsteins Legacy
Beyond Einstein will employ a series of missions
linked by powerful new technologies and common
science goals to answer these questions and
launch the revolution of the 21st century!

• Einstein Great Observatories providing
  breakthrough increases in capabilities to address
  all Beyond Einstein science
• LISA Gravitational waves from merging black
  holes and the early Universe
• Constellation-X Spectroscopy close to the event
  horizon of black holes and place constraints on
  dark side of the Universe
• Einstein Probes to address focused science
  objectives
• Determine the nature of the Dark Energy
• Search for the signature of inflation in the
  microwave background
• Take a census of Black Holes of all sizes in the
  local Universe
• A technology program, theoretical studies and an
  education program to inspire future generations
  of scientists and engineers towards the vision
• Directly detect the gravitational waves emitted
  during the Big Bang
• Image and resolve the event horizon of a Black
  Hole

Beyond Einstein

• Constellation-X will use X-ray spectroscopy to
  observe
• Black holes
• Probe close to the event horizon
• Evolution with redshift
• Dark side of the Universe
• Clusters of galaxies and large-scale structure
• Production and recycling of the elements
• Supernovae and interstellar medium
• 25-100 times sensitivity gain for high resolution
  spectroscopy in the 0.25 to 10 keV band
• Four satellites at L2 operating as one with
  advanced X-ray spectrometers
• Enable high resolution spectroscopy of faint
  X-ray sources

• LISA uses a laser based Michelson interferometer
  to monitor the separation between proof masses in
  separate spacecraft
• Three spacecraft separated by 5 million km
• Each spacecraft includes two freely falling test
  masses with drag free operation
• Distance changes measured with precision of 4
  ppm RMS over 100 seconds

To Inspire the Next Generation of
ExplorersEducation Initiative

• Educator Astronaut Program
• fully qualified members of NASAs Astronaut Corps
  who have expertise in K-12 education.
• Educator Astronauts will lead the Agency in the
  development of new ways to connect space
  exploration with the classroom
• more information, applications, or submit a
  teacher, go to http//edspace.nasa.gov
• Explorer Schools
• 50 Middle Schools 5 per Center to be selected
• Commit to 3-year MOU improve math and
  scienceinstruction in low performing / urban
  schools
• 6-member teams from each school / 6-day training
  session during the summer
• Pipeline Building A Pathway to NASA-related
  Careers
• engage Public and Parents as well as teachers and
  students
• emphasis on Informal (museums, science centers)
  as well as Formal education community
• increased partnerships with Dept. of Education on
  No Child Left Behind initiatives
