'Have a Plan' -- Making the Most of National Preparedness Month
By Carole Valenti
September is National Preparedness Month
and we encourage all of our Marshall Space Flight Center employees to take time during this month to address both personal and family preparedness plans.

The theme of this year's event is "A Time to Remember -- A Time to Prepare." We all know what we need to do to be prepared, but most of us never take the time to actually create a plan, much less execute the preparation phase to make certain the supplies are in place should they be needed.
April 27, 2011, is a day all of us in North Alabama will remember for a very long time. We knew bad weather was coming but no one imagined the day would end with such tragedy. The morning of April 28 dawned -- and life had changed for all of us. Homes and businesses were without power, most people had little fuel in their vehicles, countless families had little food in the house and many were low on medicines and other essential supplies. Numerous individuals lost their homes or experienced severe damage. Communication was spotty at best and quickly created a feeling of isolation.
This month is an opportunity for us to ensure we have a family plan for all types of emergencies we may face in our area, and to ensure we have the supplies in place to weather at least the first 72 hours on our own.
Make sure you have an emergency kit
for your home. Make a smaller one for each of your vehicles to stay prepared for severe winter weather or for a quick evacuation if necessary. Include plans for family members who have special needs, especially small children and elderly members. And don’t forget about your pets -- cats, dogs and even goldfish are part of the family as well.
If you don’t have a storm shelter in your home, determine the safest location available. Make sure you have room there for everyone. If not, see if a neighbor has a shelter with extra space or find the closest designated shelter in your area. Don’t wait until disaster is on the way to do some critical "discovery learning."
Create a communications plan. Your family may not be together when disaster strikes. Make sure you know how to contact each other and how to get everyone to a safe location. Create a rendezvous point outside the immediate area in case of an evacuation. Consider making prearrangements with family or friends in neighboring states if a prolonged evacuation becomes necessary.
Remember, a plan is only good if you are familiar with the directions it provides and everyone follows it.

Valenti is the emergency management director for the Marshall Center.

Dextre, Space Electrician: Canadian Robot Repairs Component on Station for First Time
From combined reports
Dextre, the Canadian Space Agency's robotic handyman aboard the International Space Station, has successfully replaced a faulty circuit-breaker box on the orbiting lab. The maneuver marks the first time Dextre has replaced defective equipment on the station.

The robot swapped the failed component for a new one, restoring part of the orbiting lab's backup electrical systems.
Known by the technical term "Remote Power Control Modules," circuit-breaker boxes that control the flow of electricity through the station's secondary power distribution system occasionally fail. Up until now, exchanging the boxes was done by spacewalkers, which always carries a certain level of risk. Dextre was designed to reduce the need for astronauts to conduct routine maintenance, allowing more time for the crew to perform other activities.
Supporting Dextre during the entire operation Aug. 28-29 was Canadarm2 -- Canada's robotic system that plays a key role in space station assembly and maintenance. The arm moves equipment and supplies, supports astronauts working in space, and services instruments and other payloads attached to the station.
Dextre was operated from the ground by robotics flight controllers at the Johnson Space Center, and supported by several teams of engineers both at Johnson and the Canadian Space Agency's Headquarters in Saint-Hubert, Quebec.

Chandra Finds Nearest Pair of Supermassive Black Holes
NASA news release
Evidence for a pair of supermassive black holes in a spiral galaxy has been found in data from NASA's Chandra X-ray Observatory. This main image is a composite of X-rays from Chandra (blue) and optical data from the Hubble Space Telescope (orange and yellow) of the spiral galaxy NGC 3393. The inset box shows the central region of NGC 3993 as observed just by Chandra.
Image right: Spiral galaxy NGC 3393 (X-ray: NASA/CXC/SAO/G. Fabbiano et al; Optical: NASA/STScI)
The Marshall Space Flight Center manages the Chandra program for NASA's Science Mission Directorate in Washington. The Smithsonian Astrophysical Observatory controls Chandra's science and flight operations from Cambridge, Mass.
Two separate peaks of X-ray emission -- roughly at 11 o'clock and 4 o'clock -- can clearly be seen in the inset box. These two sources are black holes that are actively growing, generating X-ray emission as gas falls toward the black holes and becomes hotter. The regions around both black holes are heavily obscured by dust and gas, blocking the copious amounts of optical and ultraviolet light produced by infalling material.
At a distance of 160 million light years, NGC 3393 contains the nearest known pair of supermassive black holes. It also is the first time a pair of black holes has been found in a spiral galaxy like our Milky Way. Separated by only 490 light years, the black holes in NGC 3393 are likely the remnant of a merger of two galaxies of unequal mass a billion or more years ago.
Dubbed "minor mergers" by scientists, such collisions of one larger and another smaller galaxy may, in fact, be the most common way for black hole pairs to form. Until the latest Chandra observations of NGC 3393, however, it has been difficult to find good candidates for minor mergers because the merged galaxy is expected to look like an ordinary spiral galaxy.
If this was a minor merger, the black hole in the smaller galaxy should have had a smaller mass than the other black hole before their host galaxies started to collide. Good estimates of the masses of both black holes are not yet available to test this idea, although the observations do show that both black holes are more massive than about a million suns.

NASA's Summer of Innovation Program Brings Hands-On Science and Math to Local Youth
Margie Morrow, right, an instructor at Sci-Quest Hands-on Science Center, works with Huntsville area youth at the Oscar Mason Library in Huntsville to help them explore how the balance point for their own bodies moves as they move. The exercise was part of a Summer of Innovation event sponsored by the Marshall Space Flight Center and Sci-Quest. The program also was held for sixth- and seventh–grade students of military personnel on Redstone Arsenal, as well as for local Girl Scouts troops and Boys and Girls Clubs.
The Summer of Innovation Program works with thousands of middle school teachers and students from across the country to engage students in stimulating math and science-based education programs. The program supports President Obama's Educate to Innovate campaign for excellence in science, technology, engineering and mathematics, or STEM, education. NASA's goal is to increase the number of future scientists, mathematicians, and engineers, with an emphasis on broadening participation of low-income, minority students. (Sci-Quest)
