Metallic noises echo in stella's suit; a thin layer of stiff material separates her from the deadly vacuum of space. stella collects meteoroids. ones that contain rare metals, like platinum and gold. they can be sold back home. ***beep-beep-beep*** an alarm. her controls are unresponsive. every second she drifts 1 meter further away from her space capsule. "quick, quick, think," the 60.0 kg astronaut whispers to herself urgently. as if by instinct, her training takes over. she looks down at the 26.4 kg meteoroid in her hands and quickly throws it with all of her strength at 4.8 m/s in the direction opposite to the space capsule. her new velocity, after throwing the rock, is m/s toward the space capsule. "success! "
