[QUOTE="Janx, post: 7486161, member: 8835"] thanks for getting back to me so quick. To umbran's question about her power level: not sure. The space suit was part of a fleet of these for defending the earth from ballistic attack (mass drivers pushing big rocks from Mars). So using math for evil would probably mean yes, she could. I want her constrained that she can't just fly up and superman nudge the threat away. I was trying to come up with a different approach to solving the problem (instead of brute force), and aikido inspired me to have her use the rock's momentum/direction to her advantage. Sounds like for that to work, she needs to push perpendicular, not "with" the general direction of the rock. I can change how long it takes to get from ground to space, and then from space to the rock. Mostly, I wanted a short enough time to be urgent, she she had to leave right away, and be able to exposition what's going on to the folks back home over radio for the first part of it, because people have a totally wrong understanding of what happened. the rock should be aimed off-center, it's a misfire anyway, and 100 years later, we've come back around to meet it. I can change the 100 years to whatever sounds plausible. The first strike was timed to align with Asteroid Bennu (a real supposed danger). Since this was pushed toward earth, it can be smaller, with a higher velocity. Other than space debris (dead satelites, etc), I'm not sure if there's another rock floating around for her to grab. Ironically enough, a named asteroid like Bennu coming by at just this same time would make for opportunity to be used as ammo. Or she could just grab enough matter to make a space bullet and fly with it so she can maintain acceleration on it, thus killing or deflecting the asteroid with a bullet/herself. It's heroic, and it's the kind of idea a sniper would come up with. So, it sounds like she needs a bullet that is about half the mass of the threat. Umbran suggests a smaller, faster rock. Not sure how small would work, to justify how much mass she could feasibly gather (think all that wrecked stuff from Gravity). Maybe there's 1-2 tons worth of movie-metal to grab in a hurry? Space is big and that's kinda bullcrap, but let's pretend that's possible for her to scoop up while zooming along the right path. I'm guessing that should be the limit of her power to move/manipulate anyway. Is it feasible to launch a 4 ton rock from the asteroid belt toward earth, miss (let's say somebody had second thoughts after the first launch and interfered) and have it eventually come around a century later and be a threat that our last Valkyrie can solve? Would that 4 ton rock be a threat? [/QUOTE]
