Spotlight On ...
The new Explore! Health in Space module

What do Beans and Bones and Balls

have to do with exploring health in space?

Ask the 44 librarians and after-school providers from Alabama and Mississippi who recently attended Explore! workshops at the Alabama Public Library Service in Montgomery, Alabama and the Mississippi Library Commission, Jackson, Mississippi. These fearless participants spent two days undertaking activities and learning the science behind the latest Explore! module, Health in Space. Sharing the Health in Space subject matter were Drs. Diane Byerly (Musculoskeletal Tissue Engineering Laboratory), Honglu Wu (Space Radiobiology Research Program), and Scott Smith (Nutritional Biochemistry Laboratory), all researchers at NASA’s Johnson Space Center. The attendees did bean curls (arm curls with beans!) to simulate muscle resistance in space relative to that on Earth, modeled healthy and osteoporotic bones (not just a problem for older women, but one that also plagues astronauts), bounced Earth and Moon balls, tested radiation with UV Man, and learned that it’s not just kids that use excuses for making unhealthy choices! No animals were harmed in the testing of these twelve activities, and a good time was had by all!

We cordially invite you to view the Health in Space module at http://www.lpi.usra.edu/education/explore/space_health/

Online Graduate Certificate in Community Education
The C.S. Mott Foundation has found that more than 10,000 schools in this country have community education programs. Very few opportunities exist for formal training in community education that supports community school programs. This is especially urgent now with the advent of hundreds of new and continuing after-school programs being developed as a result of the No Child Left behind Act. In cooperation with the National Community Education Association (NCEA), the University of Wisconsin at River Falls is creating a new graduate-level certificate program in community education to meet this national need.

Becky Recommends!

The following activity is the first in a series of activities on the Moon. All activities in Becky Recommends! are designed for tight budgets and tight spaces, and are always both educational and fun!

This is a terrific activity that very simply illustrates why we always see the same face of the Moon, even though the Moon rotates and revolves around us. This activity was adapted from Physics Forum.

 

The Penny Moon and the Quarter Earth

Penny and Quarter with Lincoln and Washington facing each other.

Place a penny and a quarter as shown above. The penny represents the Moon, and the quarter represents the Earth. 
The time elapsed represents one month, or one lunar cycle.

Penny is moved clockwise to previous position now above the quarter with Lincoln facing downward.

Now, move the penny clockwise to this position (making sure Lincoln is always facing Washington)

Quarter with Washington facing left. Penny to the right with Lincoln upside down facing Washington

Next move the penny to this position.

Quarter on top with Washington facing left. Penny on bottom with Lincoln facing up.

Then, move it around another quarter turn.

Last, move Lincoln back to his original position
(still facing Washington).

Questions

Question marksDid the Moon (penny) make a complete rotation on its axis?
(Yes. The Moon made one complete rotation on its axis)

Did the Moon (penny) make a complete revolution, or orbit, around the Earth? (Yes. The Moon made one complete orbit around the Earth)

What can you conclude about the Earth’s rotation and revolution from this demonstration? (The Moon’s rotation and revolution occur in the same time period, approximately one month. That is a very slo-o-o-w rotation compared to the Earth’s 24 hour rotation cycle!)

Can you and a friend explain — or demonstrate — why we always see the same face of the Moon?

Lincoln = the Moon
Washington = the Earth
1 rotation of the Moon = 1 revolution (orbit) of the Moon
Cool Stuff!!

Mission News and Science

Hubble Repair Planned
Modified from NASA News

Shuttle astronauts will make one final house call to NASA's Hubble Space Telescope as part of a mission to extend and improve the observatory's capabilities through 2013. NASA Administrator Michael Griffin announced plans for a fifth servicing mission to Hubble Tuesday during a meeting with agency employees at NASA's Goddard Space Flight Center, Greenbelt, Md. "We have conducted a detailed analysis of the performance and procedures necessary to carry out a successful Hubble repair mission over the course of the last three shuttle missions. What we have learned has convinced us that we are able to conduct a safe and effective servicing mission to Hubble," Griffin said. "While there is an inherent risk in all spaceflight activities, the desire to preserve a truly international asset like the Hubble Space Telescope makes doing this mission the right course of action."

Is the Moon Still Alive?
Modified from SCIENCE@NASA

The flight is tentatively targeted for launch during the spring to fall of 2008. A team of scientists led by Prof. Peter Schultz of Brown University has announced evidence for fresh geologic activity on the Moon. Although lunar volcanism was supposed to have ceased billions of years ago, there's at least one location on the Moon known as Ina where "outgassing" may have happened within the past 10 million years--and may still be happening today.

The scientists observed that Ina has sharp edges, which is unusual as most surfaces have been worn down by the constant rain of meteroids on the surface of the Moon.  Ina also has few craters, which suggests a young terrain, and its coloring is bright and similar to those of young craters, although it is  not an impact crater.

"Ina was first noticed by Apollo astronauts," says Prof. Peter Schultz of Brown University. Pictured right, "it's shaped like a letter D about two kilometers wide."

New Close Up of the Sun
Modified from SCIENCE@NASA

The Solar Optical Telescope (SOT) onboard Japan's Hinode spacecraft has opened its doors and started snapping pictures. Shown below is a "first light" image taken Oct. 23rd. The light and dark blobs are solar granules, masses of hot gas that rise and fall like water boiling atop a hot stove. Each granule is about the size of a terrestrial continent. SOT has no trouble seeing such detail from Earth-orbit 93 million miles away.

Hinode (Japanese for Sunrise, formerly known as Solar B) was launched on Sept 22nd from the Uchinoura Space Center in Kyushu, Japan. "It's on a mission to study the sun — specifically sunspots, which give rise to powerful flares and solar storms," says John Davis, the NASA Solar-B project scientist at NASA's Marshall Space Flight Center. Astronomers have been studying sunspots since the days of Galileo four hundred years ago, but they still don't know how to predict flares. Data from Hinode may solve the mystery.

Ozone Hole Reaches Record Size
Modified from
Earth Observatory

AntarticaFrom September 21–30, 2006, the average area of the ozone hole was the largest ever observed, at 10.6 million square miles,” said Paul Newman, atmospheric scientist at NASA’s Goddard Space Flight Center. Newman was joined by other scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) in reporting that the ozone hole over the polar region of the Southern Hemisphere broke records for both area and depth in 2006. A little over a week after the ozone hole sustained its new record high for average area, satellites and balloon-based instruments recorded the lowest concentrations of ozone ever observed over Antarctica, making the ozone hole the deepest it had ever been.

The ozone hole was unusually large and long-lived in 2006. While human-produced compounds break down the ozone hole by releasing chlorine and bromine gases into the atmosphere, the temperature of the Antarctic stratosphere causes the severity of the ozone hole to vary from year to year. Colder-than-average temperatures result in larger and deeper ozone holes, while warmer temperatures lead to smaller ones. In 2006, temperatures plunged well below average, hovering near or dipping below record-lows. These unusually cold temperatures increased the size of the ozone hole by 1.2 to 1.5 million square miles, according to an analysis completed by the NOAA National Centers for Environmental Prediction (NCEP). If the stratospheric weather conditions had been normal, the ozone hole would be expected to reach a size of about 8.9 to 9.3 million square miles, about the surface area of North America.

The ozone layer protects life on Earth by blocking harmful ultraviolet rays from the sun. The “ozone hole” is a severe depletion of the ozone layer high above Antarctica, so these regions may have received more ultraviolet light than usual. The 1987 Montreal Protocol banned ozone-depleting chemicals, but the long lifetime of those chemicals means that the ozone layer will not recover for several decades.
