		kingsidharth on Dec 14, 2010 \| parent \| context \| favorite \| on: Voyager 1 Has Outdistanced the Solar Wind Just wondering about two things: [1] If speed of the space-craft(craft) and solar-wind (wind) become equal that doesn't mean winds have stopped? That means they are same or slower than the craft. Right? [2] The time that signal from craft takes to reach us, is that accounted for in their estimation of 'how much time in...' equation? Dummy questions but just very curious.

[1] True. But the default speed of the charged particles are a lot faster than a spacecraft, so effectively they've stopped.

[2] The light travel time is on the order of hours, not significant on these scales.
