Logic Puzzles

Algebraic thinking sounds awful, but it can be fun! Try it out!

Exercises [Click for an example]

In the questions below, you need to solve problems using logic tables. Each table starts out with the NASAexplores book in all the boxes. If you click in the boxes, they will switch between the three symbols: , , and . Do not leave any boxes with a book. Be sure every box has either a or . To see a sample logic puzzle worked out, click [here].

When you complete a table, click on to find out whether your answer is correct. If you are right, will appear, and you can move on to the next question. If appears, then your answer is wrong. You can move on and come back to it later, or click on to make another attempt. If you can't work out the right answer, click on to see the answer.

Question 1
Apollo, Mercury, and Gemini were programs used by NASA to launch men into space. Each spacecraft in each program carried a different number of astronauts.

1 Astronaut 2 Astronauts 3 Astronauts Apollo Mercury Gemini
Use the logic table and the clues below to find how many astronauts were in each spacecraft. Clue 1 : Apollo carried more astronauts than Gemini. Clue 2 : Mercury could carry only 1 astronaut.

Question 2
X-planes are used to test how airplanes handle high speeds. Each plane has a maximum speed of sonic (speed of sound), supersonic (between Mach 1 and Mach 5), or hypersonic (more than Mach 5).

Sonic Supersonic Hypersonic X-43 X-15 X-1
Use the logic table and the clues below to find the speeds of each aircraft. Clue 1 : The X-43 holds the record for the fastest plane. Clue 2 : The X-15 can fly faster than the X-1.

Question 3
Each suit worn by astronauts has a different color and purpose.

Blue Orange White Flight Suit Launch Suit Space Suit
Use the logic table and the clues below to find the color of each suit. Clue 1 : Flight suits are not orange. Clue 2 : Space suits are not blue or orange.

Question 4
Jim Hutton, Dottie Metcalf-Lindenburger, and Jose Hernandez all had different jobs before becoming astronauts in 2004. What were their jobs?

Pilot Teacher Engineer Jim Jose Dottie
Use the logic table and the clues below to find the correct job for each astronaut. Clue 1 : Dottie works at a school. Clue 2 : Jose does not know how to fly.

Question 5
Here are four of NASA's centers: Glenn Research Center (GRC), Goddard Space Flight Center (GSFC), Kennedy Space Center (KSC), and Marshall Space Flight Center (MSFC). Each one is in a different state.

Alabama Florida Maryland Ohio KSC GRC GSFC MSFC
Use the logic table and the clues below to find which state each center resides. Clue 1 : KSC is further south than MSFC. Clue 2 : GSFC is in the eastern United States. Clue 3 : GRC is in the northern United States. Clue 4 : MSFC is not in Maryland or Ohio.

Question 6
John Glenn, Neil Armostrong, Marsha Ivins, and Leland Melvin all joined the astronaut corp in different years. When did they become astronauts?

1959 1962 1984 1998 Ivins Armstrong Glenn Melvin
Use the logic table and the clues below to find when each astronaut joined the corp. Clue 1 : Glenn was part of the first astronaut class. Clue 2 : Ivins has been an astronaut longer than Melvin. Clue 3 : Armstrong walked on the Moon in 1969.

Question 7
The four forces of flight are thrust, drag, weight, and lift. They are all necessary, and they all point in different directions.

Forward Back Down Up Drag Lift Weight Thrust
Use the logic table and the clues below to find which force points in which direction. Clue 1 : Thrust moves the plane forward. Clue 2 : Lift is in the opposite direction of weight. Clue 3 : Drag opposes the forward motion of the plane.
