	Interplanetary Space Missions
		Mission to study Earth's Mesosphere and Thermosphere, to be launched in 2000.
		Its principal mission is to measure the Mars atmosphere and its interaction with the Solar Wind.
		Proposed mission to pluto and the Kuiper Belt for 2006.

	Spacecraft
		The mission consists of a stationary lander and a surface rover known as Sojourner.
		The main scientific goal of the mission is to measure the mass, momentum and energy of the solar wind that somehow is transferred into the space environment around the Earth.
		Later in the mission, the Wind spacecraft will be inserted into a special halo orbit in the solar wind upstream from the Earth, at the unique distance which allows Wind to always remain between the Earth and the Sun (about 930,000 to 1,050,000 miles, or 1,500,000 to 1,690,000 kilometers, from the Earth).

	Deep Space 1
		DS 1, the first mission in NASA's New Millennium program, is powered by an ion engine known as NSTAR, a type of xenon-ion propulsion system.
		Among the other devices and techniques successfully tested during the probe's primary mission were an autonomous navigation system, a miniature camera and spectrometer, an ion and electron spectrometer, a solar-energy concentrator array, and experiments in low power electronics.
		An extended mission culminating in an encounter with comet Borrelly began in September 1999 but was soon threatened by the failure of the craft's most important navigational instrument, its star tracker, which enabled DS 1 to orient itself relative to stellar patterns.

	Low Cost Lunar Mission for the Year 2000
		Interplanetary exploration is a risky and costly endeavor.
		Interplanetary missions are driven by scientific objectives, and consequently a generic bus should provide an attractive platform for a wide range of missions.
		Missions requiring closer proximity to the lunar surface, such as a high resolution surface mappers, are naturally of shorter duration.

	Interplanetary
		A 413kg interplanetary spacecraft launched on the 24th January 1969 on an Atlas Centaur D from Cape Canaveral, with the mission to study Mars.
		The mission proved extremely succesful in the lunar mapping phase, but the astroid fly-by had to be abandoned on its outbound journey due to failure of the propulsion system resulting in uncontrolled spin.
		Its mission is to map the lunar surface composition, measure its gravity and magnetic fields, and to investigate the Clementine measurements seeming to indicate the existance of trapped ice on the lunar southern pole.

	IMIS 1968
		The Boeing spacecraft for the Mars mission used five modular PPM Nerva nuclear thermal rocket stages to boost several unmanned probes, a manned MEM lander, a MM Mission Module crew compartment, and a biconic EEM Earth Entry Module for re-entry into the earth's atmosphere at the end of the mission.
		The missions are broken into various mission classes such as opposition, conjunction, and swingby for Mars, and short-stay and long-stay time mission to Venus.
		The mission module total mass was a function of mission time, since consumables and spare parts would vary according to the mission length.

	Small satellites may play big role in future interplanetary missions
		But some forward thinkers are already looking ahead to interplanetary missions and see small satellites as a good fit with the space exploration agendas outlined by the world’s spacefaring nations.
		The proposed Venus Entry Probe mission is only one of a half-dozen mission ideas the European Space Agency is considering as it looks ahead to the 2015-2025 timeframe to try to understand what technologies it should be investing in now.
		Carroll said the team is still trying to line up a funding commitment for the mission, which he said could be done for a “Canadian-sized prize” of just a few million dollars provided accommodations for the tiny nanosatellite can be secured aboard some future Moon-bound orbiter.

	Study
		Thus, EP can significantly enhance or even enable advanced scientific missions (see Table I) and it could be considered to be the 3rd major step in rocketry development, following the introduction of solid propellant chemical rockets at the beginning of the 13th century and of liquid propellant chemical rockets in 1926.
		By nuclear—electric interplanetary cruise, a useful mass (final s/c—mass minus mass of power and propulsion units) of about 2 tons can be taken to "Fortuna" within about 2 yrs.
		It is true that there exist programs and proposals of a conventional Mercury—Orbiter mission (using 4 swingbys) and of a Pluto—flyby (with Jupiter´s gravity assist and 15 yrs of cruise time or directly in 8 yrs with a small Proton—launched spacecraft).

	Ross McCluney Response to George William Herbert, 28 August 1997
		Timescale of missions: Cassini was designed in the early 1980s and the design had to be frozen using components available at that time.
		The time scales of spaceflight and mission development require that you freeze a design to allow it to be properly analyzed before it is flown, and then built.
		There are investegations and proposals for solar/battery missions, where large solar arrays charge batteries up and instruments and radios are run for a small percentage of the time (minutes or hours a day, depending on the distance from the Sun and the mission).

	Computing low-thrust spacecraft mission
		"We analyzed a number of proposed missions, including a rendezvous with the asteroid Vesta, a mission to Mars and a Pluto flyby," said Coverstone-Carroll, who presented the team's findings at the American Astronautical Society/American Institute of Aeronautics and Astronautics national meeting in Monterey, Calif., in February.
		With the U. of I. algorithm, the automated search procedure provides a mission planner with an array of compromise solutions trading off such system performance characteristics as time of flight and amount of propellant consumed.
		While not practical for manned missions, where time of flight must be minimized, low-thrust systems could be used for supply missions, sample-return missions and rendezvous with distant planets.

	SMART-1: the lunar adventure begins
		So, there are many unsolved questions about the Moon, even though six NASA Apollo missions and three unmanned Soviet spacecraft have landed on it and brought back rock samples.
		In a not-too-distant future, scientific satellites will be able to 'find their way' with a minimum of ground control, just by using stars and other celestial objects to guide themselves along predefined paths.
		As for communications, engineers need to develop new and efficient ways to communicate with Earth from deep space, for interplanetary missions that are long or go far.

	Timekeeping in the Interplanetary Internet
		The mission of this project is to develop an understanding of the timekeeping issues in the IPIN, including Mars missions and beyond.
		The technology must be able to Extract ephemerides data from mission housekeeping files both on Earth, the spacecraft bus and Mars orbiters to compute range and range rate for useful transmission opportunities.
		However, all this means is that the clock discipline tuning parameters for near-Earth baselines might be quite different for interplanetary baselines and the accuracy and precisions achievable might not be nearly be as good.

	SSPVSE Posters
		Characterization of the ionizing radiation environment is challenging because the interplanetary plasma and radiation fields are modulated by solar disturbances and the radiation doses received by astronauts in interplanetary space are likewise influenced.
		Arguments to explain the exceeding of this limit during these SEP events invoke either interplanetary conditions that inhibit the amplification of waves resonating with the streaming particles, or the presence of interplanetary structures able to confine and/or mirror energetic particles.
		The sporadic occurrence of extremely large solar energetic particle events, usually associated with intense solar activity, is a major concern for Lunar and Mars missions because of the possible manifestation of acute effects from the accompanying high doses of such radiations, especially acute radiation syndrome effects such as nausea, emesis, hemorrhaging or possibly even death.

		One useful mission for this near-term technology would be to deflect an asteroid that could collide with the earth.
		Project Daedalus was a study conducted between 1973 and 1978 by the British Interplanetary Society (BIS) to design a plausible interstellar unmanned spacecraft that could reach a nearby star within one human lifetime (set to be 50 years).
		Several rocket designs using this reaction were proposed, ones using all-fission for interplanetary missions, and others using fission-fusion (effectively a very small version of Orion´s bombs) for interstellar ones.

		A stinging report on the demise of the space shuttle Columbia is increasing congressional pressure on President Bush to resolve long-postponed questions about his plans for space, but aides said yesterday that he plans no immediate upgrade of NASA's budget or mission as the space agency struggles to restart the shuttle program.
		Administration officials disclosed in an interview that the White House will begin work next week on a blueprint for interplanetary human flight over the next 20 or 30 years, with plans calling for Bush to issue an ambitious new national vision for space travel by early next year.
		The officials said they will wrestle with the military's role in space, as well as with whether to emphasize manned or robotic missions, whether to build a base in space, what vehicle should replace the shuttle and what planets should be visited.
