NASA Honored the Past and Opened the Future in 1998

The space agency celebrated its 40th anniversary in 1998 by linking its past to its future. John Glenn returned to space after 36 years to research the similar physical effects that aging and spaceflight have on humans. The biological effects of spaceflight will be one research component of the International Space Station, which began construction in 1998. Here are the top NASA stories for 1998:

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 apparently that has been ejected into deep space by its parent stars.

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.

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.

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.

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.

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. (Ozone animation.) Later in the year, NASA satellites showed that the geographic area covered by Antarctic ozone depletion was the largest ever.

NASA Studies La Nina

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

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.
