Same huge annoying plot hole as in Man of Steel (2013)

"Go colonize Mars instead".
What was the point of the mission? To save humanity.
How? By evacuating all of Earth on huge space stations to another planet, accessible through a black hole near Saturn... And you need to gather data about the singularity to finish the antigravity equation to do it.
1 direct trip from Earth to Saturn = 8 ROUND trips from Earth to Mars.
So... "Go colonize Mars instead".
Also, the robot design was very impractical.
P.S. Who colonizes/lands on a planet with a "1 hour = 7 years outside" time anomaly?! Pointless suicide!.
