  1. I wonder if the booster's onboard camera used to get gunked up from stuff burning off of the grid fins...because the view stayed clearer this time.
  2. I really want to see video of the landing taken from the barge.
  3. WooHoo! Go Bulgariasat!
  4. Why does the Space Shuttle show two launch failures? STS-51L was a launch failure, but all other STS flights successfuly placed their payloads into orbit. Or do all of the other failure numbers take into account failures of their payloads to complete their missions? If so...why does Buran show two flight successes...the first Energia mission failed to put its payload into orbit as planned.
  5. They should have the second stage land onto a support cradle...no need for legs. They want to do that eventually with gigantic ITS boosters, so start small with the second stage landing that way.
  6. My definition says nothing about what object exerts the greatest force on the Moon. Perhaps you are thinking of somebody else's definition. And I certainly never said that the Moon orbits around the Sun and NOT around the Earth (it moves around both). My definition has to do with what objects are gravitationally bound together. If you have a group of two or more objects that are gradationally bound together as that group moves around the Sun, and if one of those objects is a planet*...then the smaller objects in that bound collection get classified as moons (or moonlets, if smaller than some as yet undefined limit). So our Moon is a moon of Earth. It doesn't matter to my definition how strong the Sun pulls on the objects in the bound collection compared to how strong they pull on each other (as long as the Sun doesn't pull strong enough to disrupt the system). The fact that both the Earth and Moon move in wobbly paths around the Sun during the course of a year does not affect my definition. *...or dwarf planet, or minor planet...
  7. I don't understand your point. Yes, the Earth and Moon and Jupiter and Charon and any other object that is in a planet/moon system follow paths with different degrees of wobble in their paths as they go around the Sun. Why would you think I claimed otherwise?
  8. Why is this a problem? The Moon DOES go around the Sun. The moons of Jupiter DO go around the Sun. Apollo 8 was going around the Earth along with the Moon back in 1968. Charon goes around the Sun. BUT...these objects also go around other objects as they go around the Sun. So, in addition to going around the Sun, our Moon is gravitationally bound to the Earth and goes around the Earth (and would continue to do so if you remove the effects of the Sun). This is why our Moon is classified as a moon of a planet, even though it also is going around the Sun. Our Moon is also going around the center of mass of our Galaxy...but that doesn't affect the fact that it is a satellite of the Earth. MY point is not what happens to the Moon if you remove the Earth (YNM brought that up). My point is that the Moon would be going around the Earth whether the Sun was there or not. (But I certainly acknowlege the obvious fact that both the Earth and Moon are gravitationally bound to the Sun...it just doesn't matter to my point.)
  9. That was the Welcome mat flying off.
  10. Yes... which proves that the Moon is a satellite of the Sun. And depending on the context, we classify satellites of the Sun as Planets (if they meet all of the IAU criteria), Dwarf Planets, minor planets (asteroids), comets, etc., etc., and moons (if they are natural objects gravitationally bound to a planet and are larger than some as yet undefined lower limit...below which they could be called moonlets).
  11. The Earth and Moon are gravitationally bound together. If the Sun were to suddenly vanish, the Earth and Moon would happily continue their relative dance as the fly out into deep space together. What the Sun is causing the pair to do (arcing through space in a relatively tight curve around the larger mass) is irrelevant to this relationship. And since the Moon is the junior partner in the system, it is classified as the satellite of the Earth.
  12. Pffft. Even if doing all the reusability stuff only breaks EVEN and doesn't save any money...I'm still in favor of it for the absolute coolness factor of it all. Watching SpaceX learning to land boosters has been the best thing I've seen in rocketry in years.
  13. Beautiful! Lots of great camera work. Good job, SpaceX.
