  1. Technology Timeline By Kevin Downey, 6C Science

  2. SCUBA • Full title: Self-Contained Underwater Breathing Apparatus • Modern form first used in: 1943 • Invented by: Jacques Costeau and Emile Gagnan • PSI inside diving cylinders: 2,900-4,400 • Fate: Still used today A manta looms out of the darkness, close to the SCUBA diver

  3. Bathyscaphe Trieste • First used in: Challenger Deep, 1960 • Crewed by: Lt. Don Walsh and Jacques Piccard • Achievements: Made it to Challenger Deep • Fun Fact: Was used by Italy before the U.S. Navy bought it and sent it to Challenger Deep • Fate: On display in a museum The Trieste surfaces after its historic dive.

  4. The Eagle • First used: The Moon, 1969 • Crewed by: Neil Armstrong and Buzz Aldrin • Achievements: Putting man on the moon • Fun fact: On the abandoned legs of the Eagle, there is a plaque commemorating the occasion, and a Patch which remembers the crew of Apollo 1 (who died in a pre-launch failure). • Fate: Partly on the moon, partly at the bottom of the ocean. Two extreme environments in one! The patch that was left behind on one of the legs.

  5. Helios 2 • First used: 1976, 43,000,000 km from the sun • Achievements: Studied the sun, solar wind, solar plasma, cosmic rays, and cosmic dust • Designers/Users: Built by Germany, used by the US • Fun Fact: Helios 2 is the fastest thing ever built by man, reaching speeds of 252, 792 km/h. It reached these speeds because of its elliptical orbit around the Sun, which flung it to extreme speeds • Fate: Still whizzing around the Sun The prototype

  6. Challenger • First used: 1986, Earth`s orbit (planned) • Mission: Deploy a satellite • Crewed by: Michael J. Smith, Dick Scobie, Ronald McNair, Ellison Onizuka, Christa McAufille, Greg Jarvis, and Judith Resnik. • Fate: Disintegrated 73 seconds after launch • Cause of breakup: O-ring failure, high winds Challenger begins its breakup

  7. Deep Worker • First used: Stallwagen Bank, 1999 (used to quantify fish species) • Achievements: A very speedy and versatile submersible • Designers: Nuytco Research Limited • Fun Fact: It is powered by foot pedals, giving the pilot a very intuitive method of steering.
