Puzzle 1

Content:

To start your mission you must get the rocket to take off ASAP. What is the minimum speed that the rocket has to achieve to get away from the Earth's gravity? (Round to the nearest integer).

Hints:

  • The speed that you need to compute is known as escape velocity
  • The formula is √ (2 * g * R)
  • The speed is 11.29 km/s, so the solution is 11

Solution: 11

Puzzle 2

Content:

We have managed to take off! We are headed towards our destination. Now we must access the onboard navigator to be able to operate the rocket during the trip. The access code is made up of the digits corresponding to the color of the four planets that are part of our route. 

To obtain each digit you must use the navigation disk. In this galaxy, black points north. 

 

What is the access code?

Hints:

  • The first planet is yellow, then grey, then blue and lastly red.
  • You must spin the disk so black points towards the North.
  • Each planet color corresponds to a digit.
  • The access code is the combination of the digits corresponding to the color of each planet in the order in which they are on the route.
  • The code is 1089

Solution: 1089

Puzzle 3

Content:

You have successfully accessed the browser. You have received a message with landing instructions. For security, the message is encrypted with a Caesar encoding  (the key is the number of Kepler's laws):

Hints:

  • Decode the message that has been coded using the Caesar cypher
  • Caesar cypher requires a number of positions shifted, in this case, the number of Kepler's laws
  • The key is 3
  • The station is Copernico

Solution: Copernico

Puzzle 4

Content:

We are about to reach Planet B, but... will you be able to go down to the surface when you arrive? The ladder only supports 4000 Newtons. Your weight with the package on Earth is 900 Newtons, but this planet, although it has the same mass, has half the radius. What is the corresponding weight on Planet B?

Hints:

  • To calculate the weight on Planet B, you must calculate how many times the gravitational constant on this planet is higher than on Earth.
  • The gravitational constant g is calculated as g = GM/R^2
  • Since the radius is half that of Earth, the gravitational constant will be 4 times that of Earth. Therefore the weight will also be.
  • The weight is 3600 N.

Solution: 3600

Final

We have arrived at Planet B! Luckily the ladder supported all the weight and we were able to deliver the package with the medication for the sick astronaut on time. You have completed the mission successfully!
