Actually the shuttle spent MANY years as old hat. It after the first 3-4 years it only really made the news 3 times. The two explosions and the last missions.
I got to take a private tour of the SpaceX testing facility in Texas a few weeks back, I was a few feet away from the team installing the flight computers on top of the Stage 1 in the hanger in McGregor a few weeks back.
Amazing stuff to see in person, and really emotional to see the same Stage 1 launch today and land.
(On another note, the people in the hangar were listening to Katy Perry as they were working. Sorry guys, I had to.)
IIRC (it has been a long time since I studied physics), mass was measured in Newton's. The definition of weight as distinct from mass is that all matter has mass all the time, but it only has weight when that mass is experiencing the force of gravity within a gravitational field.
the Kilogram is a measure of mass. However, due to the way that scales and the like are calibrated here on earth, it corresponds to the weight as well. Force is measured in Newtons (F=ma), so if you hold a 1kg object suspended in the air, you need to apply 9.8 newtons of force to prevent it from moving.
Which is what I always had hoped for the shuttle program

This post demonstrates that any sufficiently advanced idiocy or ignorance is indistinguishable from trolling.
