      From: snidely.too@gmail.com              Niklas Holsti asserted that:              > Such a landing would occur on the far side of Mars, as seen from Earth, so       > direct telemetry from the lander to Earth would be impossible, in addition to       > the problem with the extra rotational velocity. Nowadays one could relay       > telemetry via some Mars orbiter, but at extra risk.              That's exactly what was done; MRO for real-time, Maven for tape-delay       but covering longer post-landing for the self-check reports.              After cruise stage jettison, Persey's direct-to-earth was tone with       only limited encoding (heart beats, mainly).              /dps              --       "Inviting people to laugh with you while you are laughing at yourself       is a good thing to do, You may be a fool but you're the fool in       charge." -- Carl Reiner              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
