(Johns Hopkins University)
Paul D. Feldman is currently professor in the Department
of Physics and Astronomy at Johns Hopkins University
where he has been since 1967. His recent work has
been in space ultraviolet astronomy and spectroscopy.
He is principal investigator of a NASA-supported
sounding rocket program and has been responsible
for over three dozen sounding rocket launches primarily
for the study of the Earth's upper atmosphere, the
aurora and the airglow, the atmospheres of comets
and planets, the spectra of hot stars, and cosmic
background radiation. This program also developed
the UVX experiment which flew on the Space Shuttle
Columbia in January 1986. He was principal investigator
for a program of comet studies (which included comet
Halley in 1985-1986) using the International Ultraviolet
Explorer satellite observatory. Dr. Feldman is a
co-investigator on the team which developed the
Hopkins Ultraviolet Telescope for FUV astronomy
as part of the Astro payload that flew on the space
shuttle in December 1990 and again in March 1995.
He is a General Observer with the Hubble Space Telescope
and served on the Space Telescope Users Committee
from 1992 to 1995. He is also a member of the FUSE
science team and a co-investigator on the HST Advanced
Camera for Surveys.

Weaver |

(Johns Hopkins University)
Weaver has been pursuing space-borne, rocket-borne,
airborne, and ground-based investigations in planetary
science since 1978. His thesis work involved analyses
of cometary spectra obtained with the NASA/ESA International
Ultraviolet Observer (IUE) satellite and was the
first systematic investigation of cometary ultraviolet
emissions.
In 1985-1986 he made infrared observations of Comet
Halley from the NASA Kuiper Airborne Observatory
(KAO), which resulted in the first unambiguous detection
of water in comets. For this latter work, he was
awarded the NASA Medal for Exceptional Scientific
Achievement in 1988.
During the past decade, he has led many investigations
of comets using the NASA/ESA Hubble Space Telescope
(HST). Weaver was the Principal Investigator (PI)
on the first HST spectroscopic observations of a
comet in September 1991, which resulted in the discovery
of the CO Cameron bands, a unique tracer of CO2
in comets. He was the PI on the main HST program
to study Comet D/Shoemaker-Levy 9, which plunged
into Jupiter's atmosphere in July 1994, and he also
served as the Chair of the Science Observing Team,
which oversaw the entire HST Comet-Jupiter impact
campaign. For this latter work he received a NASA
Group Achievement Award. He also led HST investigations
of Comets Hyakutake, Hale-Bopp, C/1999 S4 (LINEAR),
and several others, and he is a member of the team
using HST to measure the sizes, shapes and colors
of cometary nuclei.
Weaver is currently participating in a program
to study comets with FUSE; more than 60 new emission
features have already been discovered during that
investigation, including the first detection of
H2.
In parallel with his UV studies, Weaver has also
continued his infrared and radio investigations
of comets, using ground-based facilities at the
IRTF, Keck, JCMT, CSO, and IRAM observatories.
During the summer of 1996, asteroid 1984 FN was
renamed to asteroid "Halweaver" in recognition
of Weaver's work on the chemical composition of
comets.
Weaver has published over 90 papers, including
studies of planets and their satellites in addition
to comets. He has a longstanding interest in research
on the formation and evolution of planetary systems
and, in particular, wants to investigate possible
connections between cometary matter and interstellar
material in star-forming regions.
