We have been preparing for years for the critical events the spacecraft must execute on Friday.

For the last six minutes, we are essentially in white-knuckle time, wondering if we're going to actually complete the burn and go into orbit.

It was picture-perfect. We couldn't have scripted it any better.

It's the most technologically advanced satellite we've ever sent to another planet.

There is no time for the team as a whole to react ... so we have on board all the programs we need to carry out, and the spacecraft has to do it all on its own.

This spacecraft is going to rewrite the science textbooks on Mars.

The celebration feels great, but it will be very brief because before we start our main science phase, we still have six months of challenging work to adjust the orbit to the right size and shape.

We're getting into the dangerous portion of the mission. Now we're starting to enter into the realm where we've lost two spacecraft in the last 15 years.

The team did a great job of planning and implementing the acquisition of these very difficult images.

There is risk every time we enter the atmosphere, and we are fortunate to have Mars Global Surveyor and Mars Odyssey with their daily global coverage helping us watch for changes that could increase the risk.

We have been preparing for years for the critical events the spacecraft must execute on Friday. By all indications, we're in great shape to succeed, but Mars has taught us never to get overconfident. Two of the last four orbiters NASA sent to Mars did not survive final approach.

Our spacecraft has finally become an orbiter. The celebration feels great, but it will be very brief because before we start our main science phase, we still have six months of challenging work to adjust the orbit to the right size and shape.

They say you're born with it, the gift, ... I think that's the case with Nick. He just grew up wanting to be a player.

They're bringing their data back, we think, through a straw. We're going to start opening up the fire hose ... We're going to be awash in data that will allow us to better understand the planet as a whole.

Each time you dip into the atmosphere, you have to be very attentive because if you dip in too far ... it can be detrimental to the spacecraft, ... We have an atmosphere we don't fully understand. ... There are a lot of people who lose a lot of sleep.
