"Just a little while ago our deputy administrator announced that 2020. Looking at the fall of 2020. That's the goal we're shooting for. We're on schedule for that. There's always risks to that schedule is the first time we're building this rocket is the world's most powerful rocket as far as payload capability and for us. So you know it's always risks to that but we feel good that we're making all the lessons learned from the earlier build techniques are being used and we're getting more efficient and we're learning as we go."

6. SOUNDBITE (English) Ricky Arnold, NASA astronaut:
"We'll be walking somewhere instead of floating. I was saying that this morning we. That was one thing you miss is being on your feet and to go explore other planetary surfaces starting with the moon. And this vehicle will get us there. That's really exciting though the possibilities are limitless."
A NASA official says some crews are working around the clock at the space agency's rocket factory in New Orleans to meet a fall 2020 test launch deadline for a mega-rocket designed to propel astronauts toward the moon and Mars.
Deputy Administrator James Morhard said he visited the Michoud Assembly Facility at midnight and people were working on the engine section for the 212-foot (65-meter) core of the Space Launch System.
The other four sections have been assembled, and NASA says the rocket's core section is 80 percent complete.
Morhard wouldn't say whether he expects NASA to get the $1.6 billion requested by President Donald Trump for space exploration.
He says he's waiting to see what the Senate does with the proposal.
