NASA offers live interviews with Hubble experts for 20th anniversary

WASHINGTON -- On the eve of the Hubble Space Telescope's 20th
anniversary, NASA will offer live satellite interviews with two of
the telescope's premier scientists: Ed Weiler, associate
administrator of the Science Mission Directorate at NASA Headquarters
in Washington, and former astronaut John Grunsfeld. Interviews are
available from 6 to 9 a.m. EDT on Friday, April 23.

To participate, reporters should contact Al Feinberg at 202-358-1058
by noon on Thursday.

Weiler has worked on the Hubble project since the mid-1970s, while
Grunsfeld, who is now deputy director of the Space Telescope Science
Institute in Baltimore, participated in three spaceflights to service
the observatory.

Hubble was launched April 24, 1990, as the world's first space-based
optical telescope. Weiler and Grunsfeld will discuss the challenges
and successes during its two decades in orbit. Hubble's observations
have provided the deepest views of the cosmos ever and captured the
minds and imaginations of people around the world.

Friday's interviews will be conducted on the NASA TV Live Interactive
Media Outlet Channel and carried live on the NASA TV Public and Media
Channels. For NASA TV coordinates and downlink information, visit:
