 STS-97 Launch, Oct 31, 2000

This is one of the shuttle ascents for the ISS (International Space Station).
Vi_mph (inertial velocity) is in miles per hour, and includes a contribution from the Earth's rotation. (Great question: how much is that at the Kennedy Space Center? Needs trig.)

We do not know what all the things in the What column are. We know some, e.g., SRB = Solid Rocket Booster. MECO = Main Engine Cut-Off. We were curious about the single-engine Zaragoza--it sounded like a dance, or perhaps a figure-skating move--but readers responded with the explanation: Zaragoza is an alternate landing site in Spain that, after reaching a certain altitude, the shuttle can make on one engine if they decide to abort the mission.

Questions: What is the acceleration of the shuttle during this ascent? How does it change? When is it at a maximum? How can you explain the overall pattern?

Note: you may need to create a new variable, time, out of the minutes and seconds variables (into which we have decoded Tplus).
