  1. 4. I orbit Earth without a sound, transmitting signals round and round. GPS and weather maps are mine — I keep your phone and TV fine. What am I?
  2. 7. I keep a spacecraft pointing right, maintaining orientation in flight. Spinning fast inside your craft — without me, missions drift fore and aft. What am I?
  3. 8. I hold the rocket before it flies, a concrete throne beneath the skies. Fueled and bolted, armed and ready — I keep ten million kilos steady. What am I?
  4. 10. I'm the stream of data sent from space, reporting speed and health and place. Engineers watch me on their screens — I tell the story behind the scenes. What am I?

  1. 1. Two spacecraft meet and clasp in space, a careful, choreographed embrace. The ISS knows me very well — a perfect link no gravity to tell. What am I?
  2. 2. I protect against the blazing burn, as spacecraft home begins to turn. Ablative layers take the heat — without me, reentry ends in defeat. What am I?
  3. 3. I'm the nose cone shielding the prize, protecting the payload as it climbs the skies. Once in space, I split in two — my job is done, the payload breaks through. What am I?
  4. 5. I give the rocket its first mighty shove, strapped to the side and pushing from above. Once fuel runs dry, I fall away — SpaceX taught me to land and stay. What am I?
  5. 6. I'm the fiery plunge back home, through atmosphere, no more to roam. Shields must hold or all is lost — this dramatic phase comes at great cost. What am I?
  6. 9. I reach across the void of space, sending signals from place to place. Dish-shaped often, tall and wide — ground control speaks through my side. What am I?
