What were the major goals of project Gemini
- To have man and materials in space for up to two weeks
- To dock with other space vehicles
- To perfect methods of landing on a predetermined spot (This was cancelled in 1964)
What was Mercury's space flight ability? What did Gemini have to become the first to do?
Mercury could only change direction in space, Gemini had to become the first fully maneuverable
How many space flights did Gemini send up between April 1964- November 1966? How many were unmanned
12, the first 2 being unmanned
What was the purpose of the first Gemini flight?
Test the compatibility between the Gemini craft and the Titan II rocket
What was the purpose of the second Gemini flight?
Test the launch and re entering systems
Who piloted the first manned Gemini craft, Gemini 3?
Gus Grissom (First man to fly into space twice) and John W. Young
What was the primary purpose of Gemini 3
To test the maneuverablilty in space
What was the difference between Gemini's landing and Mercury's? What happened during the landing phase?
- Gemini was designed to land on it's side by parachute attaches to both ends of the craft.
- When Grissom flipped the switch to land it thrusted him forward and cracked his face plate
What was Gemini 4 the first of?
- The first long duration US space flight
- The fist mission control from Mission Control in Houston instead of Cape Canaveral
Who were the two astronauts in the Gemini 4 mission? What was their goal? What was the problem? What was the highlight?
- James A. McDivitt and Edward H. White II
- Mission was to fly in formation with the spent Titan II rocket
- They found thrusting towards the rocket moved the farther away (Later learned to drop in orbit of the object, them move on it from under)
- Highlight was the 22 minute EVA, first American EVA
Who were the astronauts of the Gemini 5 flight? What did the flight show us?
- Gordon Cooper and Charles "Pete" Conrad Jr.
- 80 day flight showed astronauts could endure weightlessness over the time it would take to reach the moon
Who were the astronauts of the Gemini 6 flight? What was the mission? What happened?
- Willy Schirra and Thomas P. Stafford
- The plan was to rendezvous with a craft in space but it exploded after launch.
- It was changed to rendezvous with Gemini 7
Who were the astronauts of the Gemini 7 mission? What did they accomplish
- Frank Borman and James A. Lovell Jr.
- They did the most experiments in space, 20, and tested the new suits which proved to be uncomfortable
- Most importantly they proved astronauts could stay in space for long periods of time
Who were the astronauts of Gemini 8? What did the accomplish?
- Neil Armstrong and David R. Scott
- They were docked with an Agena rocket (used by military to launch satellites)
- After docking it began to spin out of control
What was the reason behimd the Gemini 8 craft spinning out of control? What was the solution
- It was a stuck orbital thruster
- Armstrong turned off the thrusters and activated the reentry control rockets
Who were the pilots of Gemini 9? What happened to them though
Elliot M. See Jr. and Charles A. Basset but 4 months before flight the were in a plane crash going to the place where the craft was being built
Who were the back up pilots for Gemini 9
Thomas Stafford and Eugene A. Cernan
Make a list of the problems in relations to Gemini 9
- They tried to launch an Agena rocket for docking but it exploded
- They tried to launch an ATDA (Augmented Target Docking Adapter) but its computer failed so they had to postpone Gemini 9 launch
- It could not dock with the ATDA
- Cernan on a long EVA kept floating away and his suit couldn't handle the heat inside so his visor fogged up. He couldn't see and snagged a tear in his suit on an antenna
Who were the astronauts of Gemini 10? What went wrong in the flight?
- John Young and Micahel Collins
- NOTHING went wrong they docked with two rockets, one designed and one left over from Gemini 8. The one from Gemini 8 became the first docking done without guidance and by eye. Collins did a walk to the docked rocket which became the first person to meet another spacecraft in space
Who were the astronauts of Gemini 11? What did they experiment in space
- Pete Conrad and Richard F. Gordon
- They did a gravity experiment by connecting to vessels with a tether and having them rotate (They found there was slight gravity)
- The re-entry was the first completely controlled by computer and was within 2.8 miles of accuracy
Who were the astronauts of Gemini 12? What did they prove
- James Lovell and Edwin E. "Buzz" Aldrin Jr.
- Aldrin complete tasks outside the spacecraft proving a trained astronaut could work in space
Who became the third nation to send a someone into space? When? What mission? Who?
China in 2003 on the Shenzhou 5 spacecraft they sent Yang Liwei
What does Shenzhou stand for in Chinese
What was the first human made spacecraft to reach escape velocity?
What were the L-1 and L-3 Soviet space missions? What was their success dependent on?
- L-1 was to be a 2 man craft that would circle the moon, L-3 was supposed to be the Lunar landing
- It was dependent on the N-1 rocket
What were the three sections of the Apollo spacecraft
Command Module, Service Module and Lunar Module
What was the Command Module? What was it used for?
- Cone shaped capsule that was the crews living quarters and command center.
- It held the food, water, clothing and waste management systems
- It was the only portion which was designed to withstand the re-entry heat
What was the Service Module
- Contained the oxygen supply, propulsion system along with other systems
- For most of the mission the CM and SM were connected and referenced to as CSM
What rocket was used to launch the Apollo spacecraft
Who designed the Saturn V rocket? What else did he design for the US
Werhner von Bruan who also designed the Redstone rocket for the first two Mercury missions
What are the three stages of the Saturn V rocket
S-IC, SII, and SIVB
What is the S-IC stage of the Saturn V rocket
- 5 engines each the size of a two and a half ton truck
- 6000 pounds of kerosene/liquid oxygen
How much power does the SII stage of the Saturn V rocket have
Power of 30 locomotives
How did the S-IVB stage of the Saturn V rocket work?
It would fire the first burst after the detachment with the SII stage, the after two or three orbits it would fire again, sending the rocket to the moon
The first three Apollo rockets were unmanned missions, What were they called?
- AS-201 1st flight
- AS-203 2nd flight

- Virgil "Gus" Grissom, Roger Chaffee, and Edward H. White Jr.
- During simulation with the CM Chaffee said he smelt fire, the Grissom yelled fire and the cabin reached 1000 F before service men could open the hatch. They all three died
- The fire was blamed on a electrical spark under Grissom's seat
What happened with the Soviet Soyuz 1 mission?
Parachute failed on the re-entry process and it hit the ground instantly killing pilot Komarov

Over the next three years after the Apollo 11 flight, how many more flights landed how many more astronauts on the Moon
5 more missions landed 12 astronauts on the moon
Why did Apollo 12 fire the LM back at the moons surface after takeoff
It hit the surface, and with materials left behind, the seismic waves were used to find information about the Earth's interior
Apollo 12 found what on the moons surface?
Life on a piece of insulation left behind from Surveyor 3 (It was accepted that the organisms came from Earth)
What dangered the Apollo 13 flight?
56 hours in one of the oxygen tanks exploded, causing the other tank to fail. Also the normal amounts of Electricity, light and water was low so the only option was to swing around the moon and come back too Earth
