Mountain Views-News Saturday, January 20, 2018 11THE WORLD AROUND US STEEP SLOPES ON MARS REVEAL STRUCTURE OF BURIED ICE Mountain Views-News Saturday, January 20, 2018 11THE WORLD AROUND US STEEP SLOPES ON MARS REVEAL STRUCTURE OF BURIED ICE Researchers using NASA’s Mars Reconnaissance Orbiter (MRO) have found eight sites where thickdeposits of ice beneath Mars’ surface are exposed infaces of eroding slopes. These eight scarps, with slopes as steep as55 degrees, reveal new information about theinternal layered structure of previously detectedunderground ice sheets in Mars’ middle latitudes. The ice was likely deposited as snow long ago. Thedeposits are exposed in cross section as relativelypure water ice, capped by a layer one to two yardsthick of ice-cemented rock and dust. They holdclues about Mars’ climate history. They also maymake frozen water more accessible than previouslythought to future robotic or human explorationmissions. “There is shallow ground ice under roughly athird of the Martian surface, which records the recent history of Mars,” said the study’s lead author, Colin Dundas of the U.S. Geological Survey’sAstrogeology Science Center in Flagstaff, Arizona. “What we’ve seen here are cross-sections throughthe ice that give us a 3-D view with more detail thanever before.” The scarps directly expose bright glimpses into vast underground ice previously detected with spectrometers on NASA’s Mars Odyssey (MRO) orbiter, with ground-penetrating radar instrumentson MRO and on the European Space Agency’s MarsExpress orbiter, and with observations of freshimpact craters that uncover subsurface ice. NASAsent the Phoenix lander to Mars in response to theOdyssey findings; in 2008, the Phoenix missionconfirmed and analyzed the buried water ice at 68degrees north latitude, about one-third of the wayto the pole from the northernmost of the eight scarpsites. The discovery reported today gives us surprisingwindows where we can see right into these thickunderground sheets of ice,” said Shane Byrne of the University of Arizona Lunar and PlanetaryLaboratory, Tucson, a co-author on today’s report. “It’s like having one of those ant farms where youcan see through the glass on the side to learn aboutwhat’s usually hidden beneath the ground.” Scientists have not determined how these particular scarps initially form.

The solution to homelessness involves the cooperation of local community organizations, and the homeless individuals themselves. Though there is no shortage of people willing to assist, never forget that “assistance” is a two-way street. Mark Holsinger, Executive Director of the Los Angeles Mission, wrote a “Letter to the Editor” in the March 14, 1992 Los Angeles Times. He said, “As frustrating as it is that not all homeless people accept help, we should not forget that many gratefully accept the opportunity to change their lives. The problem for most of the homeless isn’t a lack of services or affordable housing or jobs. Theirproblem is their lack of desire to change [emphasis mine] -- to get off drugs, to function in a way that is acceptable to society, to respect others and themselves.” He adds that it’s not easy to get off the streets, but certainly possible to become a productive citizen because he works daily with those who’ve made that change.” Let’s assume you have lost your home, you have no job, and you aspire to get back to work and find a home.

I practiced for several days so that I could get it right. Then an opportunity presented itself. “Maybe,” my wife said as seriously as she has ever been, “you should do a little bit of exercise.” I get plenty of exercise,” I said rather smugly. “Oh yeah,” she said with both hands firmly placed on her hips. “Where are you getting any exercise?” “I get all the exercise I need,” I said, “by shivering out in the cold.” She looked at me for a moment and finally said, “You know that you’re a mess!” Paul said it best when he said, “For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come” (1 Timothy 4:8). The best exercise, of course is spiritual. Exercising my faith in God is the most important thing in my life. Dr. James L.
