NASA, Newseum to Debut Images from Unique Solar Spacecraft

WASHINGTON -- NASA will hold a news briefing and unveil initial images
from the Solar Dynamics Observatory, or SDO, at 2 p.m. EDT on
Wednesday, April 21, in the atrium of the Newseum. The Newseum is
located at 555 Pennsylvania Ave., NW, in Washington. NASA Television
and the agency's Web site will provide live coverage of the briefing.

Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever
designed to study the sun and its dynamic behavior. The spacecraft
will provide images with clarity ten times better than high
definition television and more comprehensive science data faster than
any solar observing spacecraft in history.

The participants for this briefing are:

Dean Pesnell, SDO project scientist, Goddard Space Flight Center in
Greenbelt, Md.

Alan Title, principal investigator, Atmospheric Imaging Assembly
instrument, Lockheed Martin Solar and Astrophysics Laboratory in Palo
Alto, Calif.

Philip H. Scherrer, principal investigator, Helioseismic and Magnetic
Imager instrument, Stanford University in Palo Alto

Tom Woods, principal investigator, Extreme Ultraviolet Variability
Experiment instrument, Laboratory for Atmospheric and Space Physics,
University of Colorado in Boulder

Madhulika Guhathakurta, SDO program scientist, NASA Headquarters in
Washington

The Newseum is a 250,000-square-foot museum of news that offers
visitors an experience that blends five centuries of news history
with up-to-the-second technology and hands-on exhibits.
