December 15, 1998


Aeronautics and space got noticed in '98 -- with the return of John Glenn to earth orbit, the start of International Space Station construction, and the discovery of ice on the moon. Background information is available to news media to illustrate the top 10 NASA stories of the year via the World Wide Web at the URLs listed. The video to accompany these stories will be available on NASA TV at noon today.

John Glenn Returns to Space

Senator John Glenn was named as a payload specialist last Jan. 16, and assigned to the crew of the Space Shuttle Discovery, which was launched Oct. 29, 1998, on a nine-day mission.

First International Space Station Assembly

Phase II -- construction in orbit -- began with the first station elements launched in 1998: Zarya in November and Unity in December. Next, the first wholly Russian contribution, a component called the Service Module, will be launched from Russia in 1999.

Hubble Takes Image of Possible Planet Around Another Star

NASA's Hubble Space Telescope gave astronomers their first direct look at what is possibly a planet outside our solar system -- one that apparently has been ejected into deep space by its parent stars.

Most Powerful Gamma Ray Burst since Big Bang

A cosmic gamma ray burst detected this year released a hundred times more energy than previously theorized, making it the most powerful explosion since the creation of the universe in the Big Bang.

Lunar Prospector Discovers Ice on Moon

There is a high probability that water ice exists at both the north and south poles of the Moon, according to initial scientific data returned by NASA's Lunar Prospector this year.

NASA Studies La Niņa

Research scientists using data from the Tropical Rainfall Measuring Mission (TRMM), SeaWiFS and TOPEX/POSEIDON missions are shedding new light on the phenomenon known as La Niņa. The images show changes in sea-surface temperature, and ocean current movement and the dissipation of El Niņo. While it is too early to draw definite conclusions, the results to date appear to confirm the onset of La Niņa-type conditions.

Antarctic Ozone Hole

In late 1997, larger levels of ozone depletion were observed over the Arctic than in any previous year on record. In 1998, using climate models, a team of scientists reported why this may be related to greenhouse gases.


A neutron star, located 40,000 light years from Earth, is generating the most intense magnetic field yet observed in the Universe, according to an international team of astronomers led by scientists at NASA's Marshall Space Flight Center, Huntsville, AL.

Pathfinder Airplane

NASA's remotely piloted, solar-powered Pathfinder-Plus flying wing reached a record altitude of more than 80,000 feet during a developmental test flight Aug. 6 in Hawaii. The altitude is the highest ever achieved by a propeller-driven craft and surpasses the official record altitude of 71,530 feet for a solar-powered aircraft set by an earlier version of the Pathfinder last summer.

Eileen Collins Named First Woman Shuttle Commander

First Lady Hillary Rodham Clinton announced from the White House in early 1998 that astronaut Eileen Collins (Lt. Col., USAF) would become the first woman to command a Space Shuttle when Columbia launches on the STS-93 mission in March 1999.
