4/19/93: JEFF LAWRENCE APPOINTED TO HEAD LEGISLATIVE AFFAIRS FOR NASA
Jeff Vincent
Headquarters, Washington, D.C.
Apr
RELEASE: 93-70
NASA Administrator Daniel S. Goldin announced today the appointment of
Jeff Lawrence, a senior congressional staff aide with extensive experience in
space and aeronautics matters, as the agency's Associate Administrator for
Legislative Affairs.
"With his considerable knowledge of the legislative and appropriations
processes, as well as space, environmental and technology issues, Jeff Lawrence
is ideally suited to serve as NASA's chief representative to the Congress
today," Goldin said.
Mary D. Kerwin, currently the acting head of Legislative Affairs, has
been named that office's Deputy Associate Administrator for Programs.
Lawrence last served on Capitol Hill as Legislative Director for former
Rep. Bill Green of New York. In that capacity, he was Rep. Green's chief staff
member on the House Appropriations Committee and its Subcommittee on Veterans,
HUD and Independent Agencies, which has authority over NASA's budget. Rep.
Green was the ranking minority member of the subcommittee.
Currently, Lawrence is at The George Washington University as Special
Assistant to the President for Federal Affairs. In that position, he serves as
an advisor to the president, faculty and administration on issues before
Congress that are important to the university and its research needs.
Lawrence has substantial experience in developing legislative
strategies and drafting specific pieces of legislation and amendments to
implement them. He traveled extensively for the subcommittee to oversee NASA's
programs.
Working with the staffs of the full appropriations committee and the
subcommittee, Lawrence helped develop appropriations bills, supplemental
proposals and conference reports and assisted the congressman in managing these
matters on the House floor.
Prior to joining Rep. Green in 1983, Lawrence was a Legislative
Assistant to Sen. Daniel K. Akaka of Hawaii, when he was a member of the House,
and to former Rep. Norman E. D'Amours of New Hampshire. In these positions he
advised the members on environmental, energy and agricultural issues.
A 1972 graduate of Colby College, Waterville, Me., Lawrence taught
English and history and coached track in Kittery, Me. In 1990 and 1992, he
received awards from the Council of Large Public Housing Authorities for
service to low-income housing and its residents. In 1987, he was selected to
participate in an exchange program between the U.S. Congress and the West
German Bundestag.

FACT SHEET: CRAF -- COMET RENDEZVOUS/ASTEROID FLYBY
SPACELINK NOTE: CRAF was not included in NASA's FY 1993 budget
request. We've left the document available for historical
reference.
The Jet Propulsion Laboratory is planning a new
exploratory mission for NASA to send a Mariner Mark II
spacecraft to encounter an asteroid, and then to rendezvous
with a comet and fly alongside it for nearly three years.
The mission is called Comet Rendezvous Asteroid
Flyby (CRAF). The spacecraft will closely examine the comet
during part of its orbit around the Sun. CRAF will launch a
heavily instrumented penetrator/lander into the comet's
nucleus to measure temperatures and chemical composition.
CRAF's other instruments will collect data on the comet's
nucleus, its coma, and its dust and ion cloud and tail. CRAF
will also provide the first close-up look at how a comet's
coma and its tail of dust and ions form.
The mission will use the Mariner Mark II class
spacecraft being developed for NASA by JPL. Mariner Mark II
is a new design approach advocated by NASA's Solar System
Exploration Committee and is intended for flights in the
1990s to the outer planets and primitive bodies, such as
comets and asteroids.
CRAF will be the first Mariner Mark II mission.
The second mission, called Cassini, will orbit Saturn and
place a probe into the atmosphere of the ringed planet's
largest satellite, Titan. CRAF and Cassini use identical
Mariner Mark II spacecraft, but each will carry unique
science instruments.
Mariner Mark II will use hardware and designs from
previous missions in conjunction with selected new hardware
designs to reduce significantly the costs of planetary
exploration.
CRAF will be launched aboard a Titan IV-Centaur
expendable launch vehicle in August 1995. The trajectory
will carry CRAF out to the asteroid belt, where a propulsion
maneuver will send the spacecraft back toward Earth for a
gravity-assist boost. CRAF will fly past Earth in July 1997
to take up its final flight path. (By using gravity assist,
NASA can launch spacecraft aboard rockets that have
less thrust than would be needed for a direct flight.)
The spacecraft would encounter an asteroid named
449 Hamburga in January 1998 en route to the comet. CRAF
would take photographs and other scientific measurements
during the encounter period. Asteroid 449 Hamburga is about
88 kilometers (55 miles) in diameter and is a carbonaceous
type asteroid.
CRAF's cometary target is called Kopff. It is
named for August Adalbert Kopff, who discovered it on August
22, 1906, during an observing session at Koenigstuhl
Observatory near Heidelberg, Germany.
Ninety-four years after Kopff's discovery, CRAF
will arrive at the rendezvous point with Comet Kopff -- in
August 2000. Comet and spacecraft will be at the distance of
Jupiter's orbit, and 850 days before closest approach to the
Sun, or perihelion. CRAF will fire its penetrator/lander at
the comet in August 2001, then will continue to fly beside
Kopff. The spacecraft will take data for a total of two and
two-thirds years, until about 109 days after they pass
closest to the Sun and are outward bound again. It will be
the first time a spacecraft will have flown in formation with
a comet, though a U.S. spacecraft, International Cometary
Explorer (ICE), flew by Comet Giacobini-Zinner in 1985 and
spacecraft from several countries encountered Comet Halley in
1986.
The comet rendezvous will allow study of matter
that scientists think is the original, relatively unchanged
material left behind when a cloud of dust and gas collapsed
to form the solar system 4.6 billion years ago. Scientists
believe comets now reside in a distant region of the solar
system called the Oort Cloud. Current theory holds that
gravitational nudges from stars in the Sun's neighborhood
send some comets from the Oort Cloud falling toward the Sun.
Later, in what has been called a gravitational
accident, a long-period comet may pass so close to a planet
that the gravitational interaction between them changes the
comet's orbit once more. The comet may become trapped, at
least temporarily, in the inner solar system and thus become
a short-period comet. Comet Kopff is one of those short-
period comets. Its closest approach to the Sun is 1.58 AU.
(An AU, or astronomical unit, is 93 million miles, the
average distance between Earth and the Sun.) Comet Kopff's
orbit carries it once around the Sun in 6.46 years.
Comet Kopff travels between a region from just
inside the orbit of Jupiter inward to perihelion near the
orbit of Mars, 220 million kilometers (140 million miles)
from the Sun. Kopff is apparently a fairly normal
short-period comet whose nucleus probably has a diameter of
about 8 to 12 kilometers (about 5 to 7.5 miles). When it is
most active (near perihelion) it spews out about a ton of gas
and dust every second.
The gas and dust form a cloud called a coma that
boils off the nucleus as the comet approaches the Sun. A
growing tail streams away from the coma as the solar wind
and light pressure from the Sun push the material away.
The CRAF spacecraft will fly extremely close to
the comet's nucleus, within 10 kilometers (6 miles). The
close-up exploration will take place before the coma and tail
begin to build. Later the spacecraft will move in and out
through the coma and down the tail to study their properties
and the complex processes occurring in them, and to collect
samples of dust for detailed analysis onboard the spacecraft.
All the phenomena associated with comets will be
the target of CRAF's instruments. And the long duration of
the rendezvous -- almost three years -- is expected to fill
in many of the major gaps in scientific understanding of the
strange objects.
The mission's scientific payload was selected in
October 1986. It will include:
* Cameras to photograph the nucleus, coma and
tail, and changes that occur as Kopff orbits the Sun. Photos
also would help scientists determine the comet's size and
structure, the location of its poles, its rotation rate and
geological structure.
* A surface penetrator-lander to be fired into
Kopff's nucleus. The instruments aboard the penetrator-
lander would collect a sample of cometary ices, study how
they change when heated, and perform a chemical analysis of
the gases released from the ice. The penetrator would bury
its tip, which will contain a gamma-ray spectrometer
measuring abundances of as many as 20 chemical elements, up
to one meter (three feet) below the comet's surface. The
penetrator wil carry accelerometers to determine Kopff's
surface strength and its resistance to puncture, and
thermometers to measure temperatures beneath the surface. The
penetrator/lander will radio its findings to the spacecraft,
which will then relay them to Earth.
* Mass spectrometers to study composition of gases
released by the nucleus and the cloud of plasma (ionized
gas) surrounding the nucleus.
* Dust counters, collectors and analyzers to
capture samples of the comet's dust and study them onboard.
The information would help scientists determine the chemical
elements that make up the dust and ice. In addition, the
mass, size, shape and composition of individual dust grains
will be measured.
* A visual and infrared mapping spectrometer to
study chemical composition of the coma and the surface of
the nucleus as they change with time.
* A magnetometer and a plasma-wave analyzer to
measure interactions between the coma and electrically
charged particles streaming from the Sun. The magnetometer
will also measure the comet's intrinsic magnetic field, if
it has one.
In December 2002 the spacecraft and the comet will
make their closest approach to the Sun. They will then head
outward again toward aphelion near Jupiter's orbit. On March
31, 2003, the Comet Rendezvous Asteroid Flyby, first primary
mission of Mariner Mark II, will end. At that time the
Cassini mission, with the second Mariner Mark II spacecraft,
will be in its Saturnian-tour phase.
