NASA Daily News Summary For Release: March 30, 1999 Media Advisory m99-062 ***** Summary -- Upcoming Media Event: Landsat 7 Briefing -- Video File for March 30 ***** There are no news releases scheduled for March 30, 1999. If NASA issues any news releases later today, we will e-mail summaries and Internet URLs to this list. Index of 1999 NASA News Releases: http://www.nasa.gov/releases/1999/index.html ***** Upcoming Media Event: Landsat 7 Briefing Reviewing 27 years of environmental discovery and previewing new ways of looking at our world, NASA and the U.S. Geological Survey will brief reporters March 31 on the April launch of Landsat 7. Landsat 7 will gather data from Earth's land surface and surrounding coastal regions. Analysis of the data will provide scientists with new information on deforestation, receding glaciers and crop monitoring. The spacecraft is scheduled for launch on April 15 from Vandenberg Air Force Base, CA. The briefing will be held at 1 p.m. EST March 31 in the James E. Webb Memorial Auditorium at NASA Headquarters, 300 E St., SW, Washington, DC. The briefing will be carried live on NASA TV with two-way question-and-answer capability for reporters at NASA centers.

Before the antenna was fully deployed, the spacecraft had to stop collecting data periodically to transmit the information back to Earth. Now that the high-gain antenna is deployed, the spacecraft can study the Red Planet 24 hours a day. Video shows 1) animation of antenna deployment; 2) three recent images of Mars.

A dramatic new time-lapse movie by NASA's Hubble Space Telescope shows for the first time seasonal changes on the planet. No one has ever seen this view in the modern era of astronomy because of the long year of Uranus -- more than 84 Earth years. Uranus is now revealed as a dynamic world with the brightest clouds in the outer Solar System and a fragile ring system that wobbles like an unbalanced wagon wheel.

The program will take up to 96 teams of undergraduate students aloft this year to study the effects of microgravity on their experiments. During each two- to three-hour flight, the aircraft maneuvers through a series of about 40 steep climbs and descents that can induce about 25 seconds of a zero-gravity environment each. The KC-135A aircraft is used to introduce astronauts to the feeling of microgravity, test hardware and experiments destined for spaceflight and evaluate medical protocols that may be used in space.
