First off, each individual vehicle wouldn't have to have the power and antenna (and antenna pointing) capabilities to reach the earth. They would only have to transmit as far as the nearest base, which could be as simple as the ship they landed in. Thus, each vehicle has to have a couple of watts each for the telemetry link and any number of TV channels. Other repeaters could be scattered around the site of a lunar colony or teleoperations area, to cover areas in radio shadow or extend range. these could even be small enough to be carried and emplaced by the teleoperated vehicles themselves. In fact, with the addition of recievers, each vehicle could act as a repeater for others that got lost. The only high-power links are those at the main base, or built into the lander.

Yesterday's planned sun acquisition activity was successfully completed. Today, spacecraft activity will be limited to a cruise science memory readout for the DDS (Dust Detector) and MAG (Magnetometer) instruments. Tomorrow, another sun acquisition is planned. ___ _____ ___ /_ /| /____/ \ /_ /| Ron Baalke | baalke@mars.jpl.nasa.gov | | | | __ \ /| | | | Jet Propulsion Lab | ___| | | | |__) |/ | | |___ M/S 301-355 | It's 10PM, do you know /___| | | | ___/ | |/__ /| Pasadena, CA 91109 | where your spacecraft is? |_____|/ |_|/ |_____|/ | We do! ------------------------------ Date: 7 Feb 91 19:13:40 GMT From: att!linac!pacific.mps.ohio-state.edu!zaphod.mps.ohio-state.edu!wuarchive!rex!rouge!dlbres10@ucbvax.Berkeley.EDU (Fraering Philip) Subject: Re: Liquid SCUBA In article <1991Feb4.173100.1@happy.colorado.edu> sesharp@happy.colorado.edu writes: >On the contrary, I think the only human trials with fluorocarbons in the >lungs were to solve the insufficient surfactant problem in premature babies. >They fill the lungs and then empty them as much as they can, leaving the >fluorocarbons to hold the small air sacs open.

Reasonable topics include: * Results of tests of new space related products * New product announcements * Contracts won or lost by space related companies * Sudden stock price swings * Space related startups needing venture capital or going public In general any space related investment opportunities or any events affecting these potential investments are fair game.
