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. - end - Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:930419.SHU KSC SHUTTLE STATUS REPORT 4/19/93 KENNEDY SPACE CENTER SPACE SHUTTLE STATUS REPORT Monday, April 19, 1993 KSC Contact: Bruce Buckingham Mission: STS-55/SL-D2 Orbital Altitude: 184 miles Vehicle: Columbia/OV-102 Inclination: 28.45 degrees Location: Launch Pad 39-A Crew Size: 7 Mission Duration: 8 days/22 hours KSC Landing: May 3 Target Launch Date: April 24 Launch Window: 10:52 a.m. - 1:22 p.m. IN WORK TODAY: * Launch countdown preparations * Aft engine compartment closeouts * Fuel cell storage tank purges WORK SCHEDULED: * Spacelab trace contaminant purge (Tuesday) * Crew arrives at KSC 9:15 a.m. Wednesday * Countdown begins 4:00 p.m. Wednesday * Aft confidence test and closeouts (Wednesday) WORK COMPLETED: * Ordnance installation * Auxiliary power unit catch bottle vent and drain * Hypergolic fuel pressurization * Close payload bay doors for flight * Payload bay closeouts * Spacelab closeouts and final servicing of experiments ----------------------------------------------------------------- Mission: STS-57/Spacehab/EURECA-Retrieval Orbital Alt.: 287 miles Vehicle: Endeavour/OV-105 Inclination: 28 degrees Location: Vehicle Assembly Building Crew Size: 6 Mission Duration: 7days/23 hours Target KSC Landing: May 27 Target Launch Date: May 19 IN WORK TODAY: * Installation of main engines 1 and 2 * Hydraulic fluid circulation and sample tests WORK SCHEDULED: * Heat shield installation * Aft securing for rollout * Rollout to pad 39-B targeted for April 26 WORK COMPLETED: * Installation of main engine number 3 * Hold down post plunger installation ----------------------------------------------------------------- Down Mission: STS-56/ATLAS-2/SSBUV Up Mission: STS-51/ACTS/TOS Vehicle: Discovery/OV-103 Location: OPF bay 3 NOTE: The Shuttle Discovery landed without incident Saturday, April 17, at 7:37 a.m., on KSC's shuttle landing facility runway 33.

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. ##### 8-10-88 DB Source:NASA Spacelink Modem:205-895-0028 Internet:192.149.89.61 =--=--=-END-=--=--= =--=--=START=--=--= NASA Spacelink File Name:6_8_3_4_14.TXT MGN STATUS 4/16/93 Magellan Significant Events for Week Ending 4-16-93 1.
