A free-flying observatory with a lifetime of 5 to 10 years, it would observe new comets and other primitive bodies in the outer solar system, study cosmic birth formation of galaxies, stars and planets and distant infrared-emitting galaxies o Mars Rover Sample Return (MRSR) Robotics rover would return samples of Mars' atmosphere and surface to Earch for analysis. Possible launch dates: 1996 for imaging orbiter, 2001 for rover. o Fire and Ice Possible launch in 2001, will use a gravity assist flyby of Earth in 2003, and use a final gravity assist from Jupiter in 2005, where the probe will split into its Fire and Ice components: The Fire probe will journey into the Sun, taking measurements of our star's upper atmosphere until it is vaporized by the intense heat. The Ice probe will head out towards Pluto, reaching the tiny world for study by 2016.

How do you know? >> Venus 2 Probes released? What about them? > *Don't recall Pioneer Venus 2, but PV1 may still be working. No > probes released - the Soviets do that sort of thing. Whoa! Pioneer Venus 2 dropped 5, count 'em, FIVE probes onto Venus. The thing looked a bit like a multiple warhead missile (too much for my tastes, but it worked :-)). There was one axially mounted "Large Probe" and three "Small Probes" mounted around it. The bus entered the atmosphere too, taking data until it disintegrated. Drop probe missions: Large Probe -- 1.5 m diameter / 73cm dia pressure shell (ball) Instruments - Neutral Mass Spectrometer Gas Chromatograph Solar Flux Radiometer (~="light meter") Infra-Red Radiometer Cloud Particle Size Spectrometer Atmospheric Structure Experiment (~=?) (Probably Temp. & Press.) Nephelometer (~="cloud meter") Hard-landed on day side. Studied atmosphere, data lost on impact. Small Probes -- 76 cm dia (including heat sheild) Instruments - Atmospheric Structure Experiment Nephelometer Net-Flux Radiometer 1- "North Probe" landed on dark side (59.3 N, 4.8 long) Data lost on impact. 2- "Night Probe" landed on dark side (28.7 S, 56.7 long) Survived 2 sec after impact. 3- "Day Probe" landed on day side (31.3 S, 317.0 long). Survived 67.5 minutes (wow!) after impact. Final internal temperature 126 C. Lost due to power exhaustion? Bus -- ~2.5 m across (from picture next to worker) Instruments - Neutral-Mass Spectrometer Ion-Mass Spectrometer Survived 63 sec in upper atmosphere, fried at 120 km alt.

Hey, do you hate Russians, or what? The Soviets have done an EXCELLENT job on Venus, don't knock it: Venera 1 - 3 did fail. Venera 4,5,6 did roughly the same sort of measurements as PV 2, but IN 1970!! Dropped atmospheric study probes, died on impact. Venera 7,8 Survived impact. Venera 9,10 Survived impact 30min - 1 hour, one B&W surface panoramic image each. Venera 11,12 Atmosphere & Surface chemical studies, no images planned or taken. Venera 13,14 Two high resolution images each, 127 minutes on surface for 13 (exceeding 32 min design life, BTW), 14 lasted 57 min (same design life). Venera 15,16 Two radar mappers, covered polar regions. Vega 1,2 - Venus/Halley's Comet mission, dropped one balloon probe each to study Venusian atmosphere, in addition to landers. the landers lasted ~hour, the balloons about a day & a half. Buses went on to intercept Halley, making measurements which assisted in getting Giotto's course right, BTW. I would elaborate further, but I'm pressed for time, if you're curious, e-mail me.
