ITEM 2 EARTH DAY: "HOME"
     NASA's newest Earth Science video features four decades of 
images of Earth set to music, revealing how NASA's Earth Science 
research has helped us see our home planet in new ways.

Contact at NASA Headquarters: David Steitz, 202/358-1730.

ITEM 3 PRESERVING THE CONSITUTION

     A team of NASA scientists working at the request of the 
National Archives has proved that the containers preserving 
several pages of the U.S. Constitution are still safely 
sealed. Scientists from NASA's Langley Research Center, 
Hampton, VA, adapted a laser system from an atmospheric 
research program to peer into the encasements protecting 
three of the five pages of the Constitution. In the early 
1950s, the Constitution was sealed in specially prepared 
containers, which were filled with humidified helium to 
protect the documents. By analyzing how the water vapor in 
the containers absorbed the laser beam, the scientists 
determined that the atmosphere had not changed.

ITEM 4 LABORATORY DIRECTOR OF THE YEAR

     Donald J. Campbell, Center Director of NASA's Glenn Research 
Center, Cleveland, OH, has been named the 1998 Laboratory Director 
of the year by the Federal Laboratory Consortium for Technology 
Transfer. The award honors laboratory directors who have made 
exemplary contributions to the overall enhancement of technology 
transfer for economic development. Campbell received the award today 
at the organization's 25th anniversary in Salt Lake City, UT.

Contact at NASA Glenn:  Lori J. Rachul, 216/433-8806.

ITEM 5 HUBBLE CAPTURES IMAGES OF JUPITER'S MOON IO (REPLAY)
     The Hubble Space Telescope has captured images of a 
volcano and "snow" on Jupiter's Moon Io. Close-ups of Io show 
an eruption from the volcano Pillan, which had previously 
been dormant. Measurements at two ultraviolet wavelengths 
indicate that the volcano is ejecting sulfur dioxide "snow," 
making the plume appear green in this false-color image. 
Pillan's outburst is at least 2,240 degrees Fahrenheit, and 
the volcano ejects matter at 1,800 miles per hour.

Live Interview Opportunity: Urban Heat Island, April 22

Topic: Planting trees on Earth Day really does make a 
difference. The removal of trees and urban growth can 
actually influence big city weather. A three-year analysis of 
the Atlanta, GA area shows large urban areas can create 
their own "heat islands", with higher temperatures than 
surrounding areas, leading to increased thunderstorm activity 
during summer months and more smog.  Dr. Quattrochi and Dr. 
Luvall will discuss the phenomenon, what can be done about it 
and whether it's occurring in other major metropolitan areas.  

Talent:  Dr. Dale Quattrochi and Dr. Jeffrey Luvall
   	    Global Hydrology & Climate Center
   	    At NASA's Marshall Space Flight Center

Time: April 22, 7 a.m. - 9 a.m. EDT

To schedule an interview, call contact: Connie James, 
Marshall Space Flight Center, 256/544-2188 or pager 256/544-
1183 (PIN 0224).

Live Interview Opportunity:  NASA Rides the Crest of 
Environmental Monitoring for the New Millennium, April 22

Topics:  To celebrate Earth Day 1999, three Earth scientists 
will be available to discuss some of the environmental issues 
facing our global community as we near the end of the 20th 
century. Subjects include Landsat 7, which will keep watch 
over wilderness areas and basic ecosystems affected by an 
ever-expanding global population; the Quick Scatterometer 
mission, set for launch May 29, which will map the speed and 
direction of Earth's ice-free oceans every day and shed new 
light on global weather abnormalities like El Ninos; and 
NASA's TOPEX/Poseidon satellite, which has been measuring 
sea-surface heights and charting the topography of Earth's 
oceans to improve long-term weather forecasting and help 
prevent the loss of life by ferocious, fast-moving typhoons, 
tropical storms and tsunamis. 

Time: April 22, 5 p.m. - 9 p.m. EDT

To schedule an interview, contact: Jack Dawson or Diane 
Ainsworth, Jet Propulsion Laboratory, 818/354-5011.

Live Interview Opportunity:  NASA Uses Laser to Examine U.S. 
Constitution, April 23

Topic:  A team of NASA scientists working at the request of 
the National Archives has proved that the containers 
preserving several pages of the U.S. Constitution are still 
safely sealed and protected. The NASA team adapted a laser 
system used for atmospheric research to peer into the 
protective cases containing three of the five pages of the 
Constitution.

Talent: Dr. Joel S. Levine,  senior research scientist at 
NASA's Atmospheric Sciences Division

Time:  April 23, 6 to 11 a.m. EDT

To schedule an interview, contact Ivelisse Gilman, Langley 
Research Center, 757/864-5036.
