Still gives me chills. #5 on 10 Historic Tweets That Captivated the World mashable.com/2011/05/06/his… via @mashsocialmedia @mashable

More @MarsPhoenix data crunching hints that liquid H2O has interacted with Martian surface for ages: http://bit.ly/d2aIgy

@agupta20854 the new research doesn't imply life existed on Mars, only that Viking may have found organics after all.

Missing link? @MarsPhoenix data suggests Viking landers found building blocks of life on Mars in '76: http://bit.ly/93T0Od

RT @MarsCuriosity: Come take a look at me! Live cam & chat from the clean room now thru 6:30pm EDT Friday. http://bit.ly/dd67TN

Got Red? Today is MARS DAY at the Smithsonian @airandspace. Mars mission speakers & exhibits all day! Sked: http://bit.ly/cpLpaY

From the team: Sleep well @MarsPhoenix. One chapter ends but more waits to be written with the science you returned. http://bit.ly/9AdUOh

Final listening campaign ends with no signal detected from @MarsPhoenix. A new image shows why. http://bit.ly/9AdUOh

RT @NASAJPL: New seasons on Mars today: summer solstice for @MarsPhoenix in northern hemi, winter solstice for @MarsRovers in southern hemi

RT @NASAJPL: Not a peep from @MarsPhoenix: No signal detected in 3rd listening stint. Team assessing next steps. http://bit.ly/dkPndU

RT @NASAJPL Mars Odyssey’s 3rd campaign to detect @MarsPhoenix signal continues thru 4/9. The lander is in round-the-clock sunshine.

RT @NASAJPL: No signals from @MarsPhoenix detected in February, but we have a new pic of the lander from MRO at http://bit.ly/baD7pD

RT @NASAJPL: So far, no @MarsPhoenix signal detected during 36 Odyssey overflights this week. 24 overflights remain (thru 2/26).

via @NASAJPL Next listening campaign for @MarsPhoenix is Feb. 22-26, Odyssey will do 60 overflights. Expectations low, wishful thinking high

RT @NASAJPL: Shorty site down? U can still vote by tweeting this: I vote 4 @MarsRovers for a Shorty Award in #science because.. (add why)

RT @NASAJPL Let's help @MarsRovers roll away with the Shorty Award in #science! They're in 3rd. Vote at http://bit.ly/5tLi9J

From @NASAJPL: Listening campaign for @MarsPhoenix is over for now, w/ no signal detected. Odyssey will listen again in Feb & March.
