DEIMOS Space: Mission Analysis Expertise Mission recovery planning requires the analysis of possible failure scenarios during launch, orbit acquisition and eventually Earth escape and interplanetary navigation. Space mission analysis activities focus on the preliminary definition of space missions, so as to determine the optimal mission profile to achieve a given objective. DEIMOS Space expertise encompasses a wide spectrum of mission profiles and objectives, such as geostationary satellites, low Earth orbit missions (mainly Earth observation, remote sensing and telecommunications satellites) and elliptical orbits. www.deimos-space.com /Eng/exp_man.html

White House to Weigh Interplanetary Missions (washingtonpost.com) 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. 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. 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. www.washingtonpost.com /ac2/wp-dyn?pagename=article&node=&contentId=A61757-2003Aug28¬Found=true

Ross McCluney Response to George William Herbert, 28 August 1997 For a couple of months I've been studying the possible use of solar energy as an alternative to nuclear energy power for interplanetary space probes such as the Cassini mission scheduled to launch from Cape Canaveral this October. The use of concentrating optical systems and high efficiency solar cells for long-term interplanetary missions wonÂ’t be easy. Theoretically, yes, it is possible to design space probes for Saturn missions that are mostly solar cell, about Cassini's size, and have much less scientific return per pound because of the less mass-efficient solar cells. www.animatedsoftware.com /cassini/mh9709so.htm

The future of touch technology He is heading the effort to develop networking standards to eventually build an interplanetary Internet that could connect robots, satellites, and all kinds of equipment put into space. His work is part of several space networking projects at NASA, under the umbrella Deep Space Network, a grouping of large antennas in the United States, Spain, and Australia now in place that communicates with spacecraft and conducts scientific investigations. So he and his colleagues are researching a store and forward-type of network whereby data collected 24 hours a day by space robots, for example, could be sent to a satellite continuously, and then stored and downloaded when the Earth antennas are in the right position. www.temple.edu /ispr/examples/ex03_07_24.html

Question 5 The interplanetary extensions of the coronal holes and helmet- streamers as the origin of the magnetic structures permeating the Earth's space environment has long been recognized and studied. Here a whole set of questions can be raised about the coupling relationship between the corona and the interplanetary space, except that the physics is contrastingly different from the ones applicable to the corona-photosphere coupling. It is here that SMI has a crucial connection with Space Weather, for the understanding of coronal mass ejection must be based upon a global understanding of solar magnetic field from its emergence into the atmosphere to its possible eventual exit into interplanetary space as a mass ejection. web.hao.ucar.edu /public/workshop/smi/question_five.html   (207 words)

Heavy Traffic; Keeping Communication Lines Open in an Ever-Crowded Solar System The DSN provides radio communications for all of NASA's interplanetary spacecraft and is also utilized for radio astronomy and radar observations of the solar system and the universe. However, an ever-growing cadre of interplanetary spacecraft aimed at the planets and other bodies in our solar system have swamped the space agencys Deep Space Network (DSN). Other modifications to the DSN network include hardware upgrades at its three facilities to allow an antenna to listen to more than one spacecraft, as well as cut down the amount of set up time needed before tracking a spacecraft, effectively adding more time to actually receive and send data. www.space.com /businesstechnology/technology/dsn_future_020529-1.html   (207 words)

Star Haven will develop an interplanetary pass port program and shall contact interplanetary ambassadors to make agreements with planets and interplanetary organizations throughout the universe, to provide interplanetary immigration forms and safe space travel permits. An applicant may apply with Star Haven by providing the information needed from other planets for them to determine if the applicant is welcome on any know planet or interplanetary organization, and may be given space travel permits and passports. www.rhfweb.com /shemb.html   (335 words)

Mimosa 27, pages 20-21. "Interplanetary Travel -- At Last?" by Fred Smith Back then, things like spaceships traveling to Mars and manned landings on the moon were found usually only in magazines with strange, garish covers. But while the detail involved is fascinating in itself and there are some tense sequences involving a disastrous accident to an experimental nuclear rocket, somehow the romance of space travel is lost in the process. Okay, so two of the stalwart topics of sf, space travel and atomic power, are now with us, but not in the way that was predicted exactly and somehow unsatisfying as a result. www.jophan.org /mimosa/m27/smith.htm   (1307 words)

ch6 The interplanetary magnetic field at a particular point in space would be expected to connect to either the north or south polar regions of Jupiter at any given time. Comparison of the timing of the 10 hour intensity and spectral variations observed in the energetic electron flux in Jupiter's outer magnetosphere and in interplanetary space has caused scientists to reexamine the idea that the variations are caused by the flapping of the outer magnetosphere and equatorial current sheet in the course of Jupiter's rotation. Jupiter has thus been found to be a new source of energetic particles in interplanetary space which scientists can use to study particle propagation in the solar wind. history.nasa.gov /SP-349/ch6.htm   (10785 words)

Howstuffworks "How Interplanetary Internet Will Work" Scientists, engineers and programmers are already working to develop an interplanetary Internet that will connect us to probes and human space travelers, and allow more information to be sent back to Earth. As you move farther out into space, however, there is a delay of minutes or hours because light has to travel millions of miles, instead of thousands of miles, between transmitter and receiver. Weight -- High-powered antennas that would improve communication with deep space probes are often too heavy to send on a space mission, because the payload must be light and efficiently used. computer.howstuffworks.com /interplanetary-internet.htm   (295 words)

Active Skim View of: 1. Skyscrapers in the Sky Both space stations and interplanetary ships would probably carry enough food for their journeys, just as sea-going ships do on Earth. Unlike Willy Ley, who fled Germany when the Nazis were gaining power and the German Society for Space Travel was running out of money, von Braun decided, in his passionate and obsessive desire to build rockets and travel into space, to take a job for the German Army.

Interplanetary Transport The microwave beam is then captured by a receiver(s) on electrically propelled spaceships for interplanetary (within Solar System) as well as interstellar transport (at sublight speeds) by providing beamed power for space propulsion systems, such as those using Space Sails. While slower, orbital transfer concepts for interplanetary travel may be more cost-effective for moving large amounts of cargo. Most planets in the Solar System have magnetic fields that extend into space like a giant bubble. members.nova.org /~sol/station/interpla.htm   (1377 words)

The Interplanetary Internet NASA is already convinced: it wants to employ the Interplanetary Internet in its forthcoming Mars missions, and has plans to leave special satellites in orbit as the first step to creating Internet servers in space. Special interplanetary "gateways" will convert the Interplanetary Internet data protocols to conventional TCP/IP, connecting -- in NASA-speak -- dirt-side to space-side. Just as the terrestrial Internet brings together smaller networks in cities and countries, the goal of the Interplanetary Internet is to link together Internets on different planets and their moons. www.cs.man.ac.uk /aig/staff/toby/writing/PCW/ii.htm   (594 words)

Traveling the Outer Planets The Mir space station attempted growing crops, but for interplanetary travel, it would be a necessity to grow crops to supply people and animals with food and with oxygen to breathe. The initial stage of an interplanetary space probe will be placement in orbit around the Earth.

Solar Energetic Particle Events And Associated Shocks in the Interplanetary Medium Spacecraft observations have established direct evidence that particle acceleration occurs near all collisionless shocks found in interplanetary space, including the Earth's bow shock, shocks triggered with transient solar activity, and corotating shocks. The "solar energetic particle"(SEP) events, a time limited increases of low-energy particles, are often observed in the near earth space environment, outside the magnetosphere and in the earth polar caps (where they were discovered), but also observed everywhere in the interplanetary medium. An engineering model that will predict the level of low energy particles at a particular location in interplanetary space, when a solar coronal mass ejection has been detected is being developed. www.am.ub.es /~blai/interplanetary_UB.htm   (825 words)

Natural History: On being rarefied - emptiness of intergalactic space Leaving aside pesky chunks of rocks and boulders, interplanetary space has an average density of about ten atoms and molecules per cubic centimeter, which is about the same as the best laboratory vacuums on Earth. Like the remarkably visible rarefied comet tails in interplanetary space, gas clouds in interstellar space (with at least 100 times the ambient density) can readily reveal themselves in the presence of nearby luminous stars. Comet tails, as tenuous and rarefied as they are, represent an increase in density by at least a factor of 100 over the ambient conditions of interplanetary space. www.findarticles.com /p/articles/mi_m1134/is_n1_v107/ai_20517887   (1532 words)

chapter 6 We know that in interplanetary space there is a radial outward motion of a very thin plasma (solar wind), but its density is too low to affect the motion of grains appreciably (its effect is smaller than the Poynting-Robertson effect). It is often implicitly assumed that in interplanetary space there is a "resistive" medium that is essentially at rest. In the discussion of collision between particles in interplanetary space (e.g., evolution of the asteroidal belt or meteor streams) it is usually taken for granted that the state history.nasa.gov /SP-345/ch6.htm   (5290 words)

Outer space - Wikipedia, the free encyclopedia Outer space within our solar system is called interplanetary space, which passes over into interstellar space at the heliopause. The escape velocity to pull free of Earth’s gravitational field altogether and move into interplanetary space is about 40,000 km/h (25,000 mph or 11,000 m/s). The vacuum of outer space is not really empty, it is sparsely filled with interesting things: several dozen organic molecules discovered to date by microwave spectroscopy, 2.7 K blackbody radiation left over from the big bang and the origin of the Universe, and cosmic rays, which include ionized atomic nuclei and various subatomic particles. en.wikipedia.org /wiki/Outer_space   (1126 words)

Basics of Space Flight Section I. The Environment of Space All of the above discussion of interplanetary trajectories is based on the use of today's system of chemical rockets, in which a launch vehicle provides nearly all of the spacecraft's propulsive energy. Getting to the planet Mars, rather than just to its orbit, requires that the spacecraft be inserted into its interplanetary trajectory at the correct time so it will arrive at the Martian orbit when Mars will be there. This is due to the balanced tradeoff of angular momentum brokered by the planet's-- and the spacecraft's -- gravitation. www2.jpl.nasa.gov /basics/bsf4-1.html   (1848 words)

Interplanetary Magnetic Field (IMF) The interplanetary magnetic field (IMF) is a part of the Sun's magnetic field that is carried into interplanetary space by the solar wind. The current sheet is tilted (because of an offset between the Sun's rotational and magnetic axes) and warped (because of a quadrupole moment in the solar magnetic field) and thus has a wavy, "ballerina skirt"-like structure as it extends into interplanetary space (see the figure on the left). The interplanetary magnetic field lines are said to be "frozen in" to the solar wind plasma. pluto.space.swri.edu /IMAGE/glossary/IMF.html   (432 words)
