NASA Commentator Lori Meggs talks with Larry Palinkas of the University
of Southern California about dealing with communications problems that
will face future explorers on missions beyond low Earth orbit. For the
Communications Delay Assessment experiment now underway on the
International Space Station, artificial delays in sending and receiving
messages are put in place to simulate the delays that future explorers
will experience as they go out into the solar system, where radio waves
that travel at the speed of light will still take many minutes, each
way, to reach their destinations.
