The REMO lands on Mars.
The three trek across to the Mars 1 base camp.
Mars 1 looks intact.
The O2 generator is running also.
The computers are fried, but they brought replacements.
Jim explores the functioning greenhouse.
And finds Luke.
A tad mad
Luke:
“Where is he, where’s Woody?”
Jim: Tell us what happened here.
Luke: We fired the radar, and it came, and they all died. They all died.
But I was spared.
"
“I was spared, so that someone would be left to figure out the secret”
Ok, the crew is looking at Luke like he’s a nut job.
Phil:
“Is it just me, or is he a few meal packs short of a picnic?”
Terri:
“Low term exposure to low gravity can have an adverse impact on the brain…”
Jim:
“Or, maybe his whole crew died, and he’s been marooned alone on Mars for a year.”
Love that scene 
Luke:
"Let me understand this. Your ship blew up with all the supplies, then you emptied all the cargo out of the REMO, and it was totalled on landing.
You got no food, no water, no spare oxygen.
What kind of rescue mission is this, Jim?
Jim asks Luke for more details of what happened, and what he’s figured out since.
The Face.
Someone put it there, and it wasn’t us.

Luke shows them the structure of the signal coming from the top of the mountain.
DNA.
Jim: Like looks human.
No, close.
It comes to Jim that the signal is not a signature, but a test.
It’s asking for the right answer.
It’s asking for the missing pair of chromosomes.
To prove that we’re human.
They’re going to try to fire a radar signal with the completed DNA sequence.
They send the tiny robot to the Face.
They transmit the signal.
And…they get an invitation, in the form of an opening in the Face.
Jim, Terri, and Luke are now at the Face, standing before the opening.
Phil is with the Mars 1 lander.
Jim: “Launch at 1950 with or without us”
Terri:
“Jim you sure you want to do this”?
Jim:
“I didn’t come 100 million miles just to turn back in the last 10 feet.”
(I’ve always loved that line.)
Interesting interior -perfectly white.
