Been watching this on NASA TV. They seem pretty darn confident which is unusual for NASA unless they're very, very sure. Cool stuff.
Nope, sorry, not water, its mine. I thought I lost it.
Thanks to NASA for finding it for me.
If NASA were actually doing the Search for Life thing they always talk about they would have more biologists on staff.
This is still ongoing live on NASA TV
Impact on the Moon: question
Took an estimate, compared scaling to Mars, speed of objects at Mars is much slower than Earth and Moon but number of objects on Mars is higher because of proximity to Asteroid Belt.
Just the aliens irrigating their crops. Nothing to see here.
Methinks we now have a possible series of landing sites for an eventual Project Constellation expedition.
Without greenhouse gases earth would look like mars.
The NASA scientists estimate the new flows have a volume roughly analogous to the volume of 5 to 10 swimming pools. This is really exciting news. We can be sure the teams in charge of Mars exploration missions, currently and for the future, are eager to get more observations and analysis of these new flows.
Rough transcription:
Question: How long will it take moisture to evaporate? (from Houston Chronicle)
A. Two Regions
1. South of volcanic region
2. Another region - East of impact basin
How long to evaporate - billions of years ago when they had flows and channels, there were giant outflows massive catastrophic floods, greater than floods that ripped across State of Washington 13,000 years ago, more water flow then, compared to today.
Depends on how much water - a surface layer of water a couple of mm. thick would evaporate in hours/days.
Water in soil percolating up, coming up out of soil, form frost, comes out again, could be mediated by transfer process, by diffusion process...
We have colleagues in field who are doing calculations on paper, will dash out to a journal before long...
Q. How important is it for Rover to be there?
A. Very important
Q. When were the first "hey what's this moments? (San Francisco Chronicle) A. First moment was April 2005, second one was September 2005
Q. From Nature question:
What does it mean in terms of future modeling?
A. We don't know where water is coming from...
We don't have ... it wrong... constrains composition, how can we get an enhancement of heat, keep water warm...
... prior to MER I had not thought about groundwater, did calculations prior to this about acidic water...
MER data suggests that water started out being acidic then became less so...
If we have acidic water today... May change our understanding about geochemistry of groundwater...
IMHO.
couldn't it just be an impact from a (big) iceball that melted then evaporated?
Proof of life
Not proof of life...
Are they sure this isn't a closeup of the inside of Robert Byrd's mouth? Sure looks like his teeth and gums.
How long until somebody is selling Martian water on EBay?
ping.
Wonder what is the temperature on the surface that water flows and doesn't freeze? ????
Victoria Crater
Victoria Crater
This stereo view of Mars' Victoria Crater combines two of the three images taken by the High Resolution Imaging Science Experiment on NASA's Mars Reconnaissance Orbiter. A red-colored image was acquired with the orbiter pointed 3.84 degrees to the west and a blue-colored one with the orbiter pointed 16.2 degrees to the west.
For a 3-D view of the topography, view this image through glasses with a red filter for your left eye, and a blue or blue-green filter for your right eye. The difference in viewing angle between the two images is about 12 degrees, which is greater than the convergence angle between the left and right eyes of humans while viewing distant objects, so the vertical relief appears much steeper than is actually the case. While some of the cliffs around the crater are in fact vertical, the slopes below the cliffs are no steeper than 30 degrees.
Images from the High Resolution Imaging Science Experiment and additional information about the Mars Reconnaissance Orbiter are available online at: http://www.nasa.gov/mro.
