Ok yesterday I was reading about the lost rockets going to mars and how 3/4
do not make it. BUT this to me is a really big BUT 1/2 of the number were early soviet rockets that blew up on lift-off or going into orbit. And 1/2 of ours were early in the space program. If you start around say 1972 we started getting much better at getting the stuff up there. Personal I think the early one should not count if it vaporizes on the pad. Its a learning curve thing. -- Hike High Mountain Fish for Wild Trout |

First of all the probes going to mars are NOT rockets, rockets are used to boost
the probes into space to put them on their way to their target, but they are not inthemselves Rockets. Also a lot of things can go wrong at any point during the trip or even the way down to the planet itself. -- "In this universe the night was falling,the shadows were lengthening towards an east that would not know another dawn. But elsewhere the stars were still young and the light of morning lingered: and along the path he once had followed, man would one day go again." Arthur C.

If you start around say 1972 we started getting much better at getting the stuff up there. Personal I think the early one should not count if it vaporizes on the pad. Its a learning curve thing. OK, here is the score card for those spacecraft which left Earth orbit: USSR: MARS-1: failed on its way to Mars. ZOND-2: failed on its way to Mars MARS-2: orbiter reached Mars orbit, lander "hard-landed" on Mars (in Hellas) but returned no useful data. Orbiter arrived during major dust storm so pre-programmed orbital images were of poor quality. MARS-3: orbiter reached Mars orbit but lander "hard-landed" on Mars (in Simois) and returned no useful data. Orbiter arrived during major dust storm so pre-programmed images were of poor quality. MARS-4: launched sucessfully but failed to go into orbit around Mars (flew by). MARS-5 spacecraft: reached Mars orbit and took only 70 images plus some atmospheric and magnetic field data before its transmitter failed. MARS-6: Bus/lander launched sucessfully and lander bus flew by Mars, dropping a lander capsule which hard-landed on Mars but returned no useful data. MARS-7: Bus/lander launched successfully and lander bus flew-by Mars. Lander capsule released but missed Mars. PHOBOS-1: failed on its way to Mars. PHOBOS-2 achieved Mars orbit and approached the Martian moon Phobos, but was lost due to computer failure. US: Mariner 4: Successful fly-by of Mars with first close-up images (21) taken. Mariner 6: Successful fly-by of Mars with 75 better quality images taken. Mariner 7: Successful fly-by of Mars with 126 better images taken. Mariner 9: Successfully achieved Martian orbit, taking 7,329 images and mapping most of the planet's surface at moderate resolution. Viking-1: Successfully achieved Martian orbit. Lander achieved first successful soft landing on Mars, returning surface images and data. Orbiter mapped the surface at moderate to high resolution. Viking-2: Successfully achieved Martian orbit. Lander achieved second successful soft landing on Mars, returning surface images and data. Orbiter mapped the surface at moderate to high resolution. Mars Observer: Contact lost on approach to Mars. Mars Pathfinder: Successful landing on Mars using airbag technology. Deployed Sojourner rover for rock analysis and sent back high quality images of the landscape around the landing site as well as weather information. Mars Global Surveyor: Successful orbit around Mars. Continues to take very high resolution images and data. Mars Climate Orbiter: failed due to navigation error which sent this orbiter into the atmosphere of Mars. Mars Polar Lander: failed during final powered descent to the surface. Mars Odyssey: Successfully achieved Martian orbit and continues to take images and data. Clear skies to you. David W.
