On the left in the background is the same J-2 engine I showed . On the right in the foreground is the even larger . A single engine produced 1.5 million pounds of thrust -- as much as all three space shuttle main engines combined. Five of these huge engines generated a staggering 7.5 million pounds of thrust to power the first stage of the Saturn V moon rocket. It remains the most powerful liquid fuel engine ever developed.
In other news, I'll be out of town this weekend participating in the , a bike ride from Houston to Austin benefitting the National Multiple Sclerosis Society. (The photoblog will be on autopilot.) The Houston-Austin ride is the largest MS ride in the country, with 13,000 people participating this year! If you are interested in , please feel free.
