back to article ExoMars probe narrowly avoids death, still in peril after rocket snafu

The European Space Agency's ExoMars probe is on its way to the Red Planet – although the spacecraft may not complete its mission intact. The craft, carrying the Trace Gas Orbiter atmosphere sniffer and the Schiaparelli lander, took off on March 14 aboard a Russian Proton rocket and began circling Earth. The fourth stage of the …

Interesting, but I can't wait for Scott Manley to cover it.

He's already done similar videos on comets and meteor showers in Kerbal Space Program, which demonstrates clearly how the minute differences in velocity spread the debris out over a vast region of the orbital path.

Oh, I know. He also does some videos on rocketry news.

Russia, Mars, Why would we expect success?

Even this bizarre site knows better:

Wonder if they could slow the probe a teensie bit. Just enough to let the debris overtake the probe at very slow speed, like a couple of mm an hour. Like two lorries overtaking on a dual carriageway.

Then when it brakes properly the debris is already ahead.

Nothing they can do about the stuff hitting Mars now anyway, might as well just worry about the probe.

You can't easily brake to avoid debris, unless you know the debris definitely has the same velocity of you... that's something of an unknown. In principle, assuming that no catastrophic collision has occured, most (if not all) of the debris should be gradually moving apart laterally due to the separation event, but there is the risk that when performing the course correction to actually point at Mars, you end up pointing your spacecraft at a piece of space junk.
