Thirty second lag at best. The speed of light is not going to change for you. As old as Ron, graduated from Wheaton High (Wheaton MD) the same year. Served on Independence. Uncle sent me to defend the Med and not Nam. Anyway, I'm old and gravity sucks so ending my life on a one way trip to a dream is not a bad idea.
bs
As long as Mars has FIOS, then I'm all aboard, lol

the americans have gotten very good at this process.
but the russians have not fared so well.
are you prepared to volunteer for the 1st manned flight.
apparently you get to mars, with no plans for coming back.
i share your enthusiam for space exploration.
i had just graduated from springfield high in 1969.
my friends and i were touring the US in a trailer.
i was visiting my cousin, on a huge naval vessel in san diego,
first week of august.
neil armstrong became the symbol of the greatest accomplishment of mankind.

FYI,
NASA's Curiosity is scheduled to land on Mars at 01:30 EDT early Monday morning
(Aug 6, 2012) after traveling over 500,000 miles. It's mission is to understand the
'habitability of Mars". In other words are their conditions that could have ever supported
life on Mars ( not specifically looking for life itself )
View it at NASA TV: Live coverage begin 6PM EDT Sunday
http://www.ustream.tv/nasa
Re-entry (called the 7 minutes of terror ) begins with Curiosity hitting the atmosphere
at 13,200 Mph and using a combination of head shields, and supersonic drogue chute
to slow to 200mph, and retro rockets for the rest of the way. The rover is actually
lowered on a 'sky-crane' to hang 7.5 meters below the rocket platform, and when
the rover touches, the cables are severed and the rocket platform flies away from the rover to
crash a short distance away. This keeps the level of dust and debris at the landing site
to acceptable levels.
Landing is scheduled into Gale crater which has central 3-mile high mountain peak.
Three satellites that have been in orbit around Mars since NASA:Odyssey:2001
ESA:MarsExpress:2003,
NASA:MRO:2006, etc. will relay the spacecraft signals back to earth.
The communication will need to switch between these relay stations
during re-entry, and it's possible that communication will be lost for
for part or all of the re-entry. Communication
delay is 14 minutes for the signal to reach earth from Mars, so when we get the signal
that re-entry is beginning, the spacecraft's fate will have already happened 7 minutes
prior.
The landing results may be known immediately at landing, or delayed up to three
days if communication is lost.
