How come the scientist in the second planet is not super old?
When Cooper (McConaughey) and Brand (Hathaway) return from the ground of the first planet in Interstellar, the scientist (Romilly?) that stayed in the ship aged 23 years because of the effect of Gargantua, right?
So, when they traveled to the next planet and met Dr. Mann (Matt Damon), Dr. Mann did not age the same 23 years. He aged in the same rate as Brand and Cooper.
Everybody on earth aged 23 years, Romilly aged 23 years. So, why did Dr. Mann not age in the same rate?
I understand that as a plot inconsistency. Is there another explanation?
Best Answer
Yes, there is an explanation for that. Dr. Mann was in some kind of hypersleep. This is apparently an established technology in the film. You can see Cooper and the rest of the Endurance crew enter hypersleep during their 2 years of travel from Earth to Saturn.
It is also mentioned that Romilly could have gone to hypersleep, too, but chose not to anymore at some point since he was unaware of when Cooper and Brand would return, which is why he did age significantly (even if maybe not the entire 23 years), and why Brand assumes that he didn't go to sleep.
Brand (seeing old Romilly): Why didn't you sleep?
Romilly: Oh, I had a couple of stretches. But I stopped believing you were coming back. And something seemed wrong about dreaming my life away.
And later Dr. Mann also explains how he entered hypersleep waiting for someone to rescue him:
My supplies were completely exhausted. The last time I went to sleep, I didn't even set a waking date. You have literally raised me from the dead.
Now of course it's unclear if that hypersleep is able to completely halt any aging at all, but given the science-fiction setting it's not a big stretch to accept that it slows down aging to a large degree.

How old is Mann in interstellar?
Mann (Matt Damon), Dr. Mann did not age the same 23 years. He aged in the same rate as Brand and Cooper. Everybody on earth aged 23 years, Romilly aged 23 years.How long was Dr Mann on his planet?
Dr. Mann was marooned on this planet for 35 years, as evidenced by the 23-year time dilation on Miller, the two-year trip to Saturn and the launch of the Lazarus missions which predated Endurance's launch by ten years.How long did Romilly wait?
How is Romilly (David Gyasi), who waited 23 years for Cooper and Brand (Anne Hathaway) to get back to the ship, not totally insane? He took a couple sleep breaks but clearly spent well over a decade alone.Why did Dr Mann try to maroon the rest of the crew?
After witnessing the explosion in his landing pod, signaling the death of Romilly and hearing that Cooper survived his attack with Brand on her way to help, Mann adjusted his plan and instead decided to maroon the crew of the Endurance on the planet in order to initiate Plan B.Scientists Found a New Planet, but It Suddenly Vanished
