Four teams of scientists are racing to reach the bottom of the Marinas Trench, the deepest point in any ocean on Earth. The last time this was achieved was 1951. The Marinas Trench is seven miles deep- it is deeper than Mount Everest is tall!
Here are the four subs that are trying to win this race.
The Triton Sub (Top Left)- This three-man sub has 360 degree views out of its windows-and it is bright yellow! It is expected to take 120 minutes to reach the bottom of the trench. The US company that owns this sub wants to take members of the public to the bottom of the Marinas Trench. The round trip will cost 159 million dollars!
The Virgin Sub (Bottom Right)- This sub is based on the design of a plane.If this sub reaches the bottom of the Marinas Trench, it will be the first one-man sub to do so.
The Doer Sub (Top Left)- The backers of this sub don’t care about coming first in this race. They only want to create something that will advance science. The sub is still being built, but will have robotic arms when completed. It will take 90 minutes to reach the bottom.
The Mystery Sub (Bottom Left)- This sub is being backed by James Cameron, the famous movie director. He has kept all his plans secret, but apparently wants to pilot the sub himself.
This race demonstrates the different perspectives of the backers of these teams. While they are competing in the same race, they all have different motives for doing so.
Which sub do you think will win this race?
