    Profes sor Starr’s

    Dream Trip:Dream Trip:

  • PPR

    Professor Starr, astronomer, And all his students too Gather ‘round their telescope, The universe in view. Although bright light is all around White, red, blue and green— From planets, stars, and galaxies, And dusty clouds between—

    3

  • To see small things like asteroids And comets, Pluto too, A telescope stuck on the ground, Though good—alas!—won‛t do. “We need to get up close, fly by ... Or orbit! That‛s the key! We need some low-cost, smart, and nimble New tech-nol-o-gy!

    “What shall we do? Where shall we look? How shall we get attention? We need some clever brainwork, Some techno-intervention!” One spunky girl jumps up and shouts, “I have a brilliant flash! Let‛s call NASA! They‛ve no doubt got A technologic stash!”

    5

  • WELCOME TO

    NMP

    “You‛re right! They must, I‛ve heard that said,” Professor Starr looks brighter. “We‛ve got to find a way to make Our techno-burden lighter!” And so he visits NASA Central, In Washington, DC, Finds “NNew MMillennium PProgram,” For short, just “NMP.”

  • SunSunSun

    He pleads, “Please help! We‛ve great ideas For missions to explore Some little objects out in space Too special to ignore. But don‛t know how to get there And don‛t know how to stop Don‛t know how to start again For another planet hop.”

    7

  • The New Millennium boss replies, “We greet and welcome YOU For our job‛s to experiment With gizmos bold and new. So what new thing will boost your goal, Will serve to fill your need? More power from the sunlight? New cameras? More speed?

    8

  • “Perhaps a spacecraft small and light That doesn‛t cost a ransom To launch above the atmosphere, Now wouldn‛t that be handsome? A computer with a program To decide all by itself What pictures are worth keeping? Or a computer off-the-shelf

    9

  • “That, with a little fixing up, Could handle all the stresses Of working hard in outer space With all its harsh excesses?” Professor Starr, with knitted brow, Asks, “Aren‛t you too ambitious? How can such fantastic stuff Survive in space? It‛s vicious!

    10

  • “There‛s heat and cold and Sun that blasts All objects in its way, The zero-g, no gravity! A Galactic Cosmic Ray! And what about the vacuum? To say nothing of the shocks Of blasting off from Mother Earth, The rattles, and the knocks!

    11

  • “We scientists don‛t want to risk Our research—just in case— Our gadgets that do fine on Earth Don‛t work too well in space.” “Don‛t worry, sir,” they reassure, “We‛ll help your wish come true. We‛ll test the right technology To make it work for you!”

    Xenon gas ions now going30 kilometers persecond!That‛s about 60,000miles per hour!

    “An ion engine! That‛s the thing Our dear friend Starr can use. With its constant thrust on drops of fuel His mission cannot lose!” The NASA engineers run off To test this innovation, To find a spacecraft, plan the trip, And pick a destination.

    “Let‛s call the mission Deep Space One, And send it into space, We‛ll have it browse some asteroids, And spy a comet‛s face!” And so it does. It works just great! The mission gets an A! The ion engine‛s ready, It is proven, it‛s OK!

    Professor Starr jumps right to work. He knows just what to do! He tells his students, “Let‛s just tour An asteroid, or two. We‛ll go to Vesta, Ceres too, They‛re big, but not quite planets. We‛ll orbit each, and stay awhile And map it, sniff it, scan it.

    15

  • “We'll call the mission Dawn because It's going to explore The dawning steps to planethood, How planets were before. We'll learn about their childhood. We'll learn about their birth And how the solar system made A planet like our Earth.”

    16

  • Gladly for the Starr-y team, Dawn‛s judged a worthy plan. Technology has made it so, Has soundly bridged the span From dreamy wish to solid fact, From visions into gold. Now students of the stars will have A way to plan more bold

    Adventures using useful stuff, Devices guaranteed,

    Thanks to NASA‛s careful planning, Much by NMP,

    Listening, weighing, choosing, growing, Testing, proving true.

    “Just one last thing,” says Starr, aglow, “To NMP, thank you!”

    THE END!

  • The New Millennium Program

    NASA created the New Millennium Program to help space scientists explore space and our own home planet, Earth. With the scientists‛ advice, NMP decides what new technologies will help the most. Then, NMP finds ways to develop the technology for space, then test the new technology in space. This way, the scientists don‛t have to depend on risky technologies while doing their important science missions.
