Slingshot?

Regarding the comment that "was the first spacecraft to make use of a 'gravitational slingshot' maneouvre" - didn't Apollo 13 basically do the same thing - the moon is a satellite and not a planet, but it's still the same basic idea. --DMG413 03:28, 29 March 2006 (UTC)

actually it was the first to use the maneuver. —Preceding unsigned comment added by 70.246.204.154 (talk • contribs)

What was the difference between what the two did? How does what Apollo 13 not qualify? --DMG413 03:40, 29 March 2006 (UTC)

While apollo 13 cartianly changed dirrection it didn't really change it's speed. Our Gravitational slingshot article seems to indicate that the term can only be applied to interplanetry craft.Geni 14:38, 21 April 2006 (UTC)

Fate of Mariner 10

So what happened to this thing? Is it dead in orbit? Did it crash and burn up? 162.138.184.71 (talk) 21:36, 17 January 2008 (UTC)

Article currently says it's still orbiting the Sun. Tempshill (talk) 21:58, 11 September 2008 (UTC)

Can anyone add details of the orbit after the 3rd Mars flyby ? Even thought no longer communicating, will it make any more close flybys of Mars ? Rod57 (talk) 03:28, 18 February 2011 (UTC)

Is there any possibility of reestablishing communications ? Rod57 (talk) 03:28, 18 February 2011 (UTC)

No, unfortunately. As mentioned under the End of mission section, the spacecraft exhausted the included propellant. If the batteries were ok, the transmitter not damaged from radiation, and the overall shape of the spacecraft in decent, there would be a possibility that contact could be made for a very short period if the antenna ever happened to point toward Earth, but that is a lot of ifs, and the outlook is likely bad, especially in relation to radiation damage. The instruments on the spacecraft are far inferior to that of MESSENGER and the future launching Bepi Columbo anyway. So on the upside, we don't really need to. :) --Xession (talk) 03:35, 18 February 2011 (UTC)

After the roll control problems in Oct 1974 were any usable images obtained from the 3rd flyby ? Rod57 (talk) 04:36, 18 February 2011 (UTC)

Oh I'm sure flyby 3 was completed with success. Don't hold me to that of course but I'm relatively sure. Here is the the briefing for the mission on the PDS for a good general overview of events. Also, if you're really interested in doing some research for this mission, I have a pretty good list of places to start on my user page that would be of good use. --Xession (talk) 04:43, 18 February 2011 (UTC)

Thanks, I see the PDS says about 300 photos were taken in the 3rd encounter. That's good enough for me for now. Rod57 (talk) 03:46, 27 February 2011 (UTC)

Why did they turn off the transmitter?

Commands were immediately sent to the spacecraft to turn off its transmitter, and radio signals to Earth ceased.

Article should state: Why was this done when the propellant gas ran out? Tempshill (talk) 21:58, 11 September 2008 (UTC)
