NASA Robotic Lander Test Flight Nov. 4 Will Aid in Future Lander Designs
By Kim Newton
In This Week's Star (Click to Expand)|
NASA will conduct a 100-foot robotic lander altitude test flight Nov. 4 to mature the technology needed to develop a new generation of small, smart, versatile robotic landers capable of achieving scientific and exploration goals on the surface of the moon, asteroids or other airless bodies.

The test will begin between 10:30-11 a.m. CDT and will air live on NASA Television's Education Channel and the agency's website. The outdoor test will occur at the U.S. Army's Redstone Test Center on Redstone Arsenal and is weather dependant.
The lander prototype will perform an autonomous hover test, flying up to 100 feet and then translate, or move sideways, to perform a controlled, safe landing 30 feet away from the launch pad. The lander, dubbed Mighty Eagle, is fueled by 90 percent pure hydrogen peroxide and receives its commands from an onboard computer that activates its onboard thrusters to carry it to a controlled landing using a pre-programmed flight profile. This series of tests demonstrate the test article’s capability to perform an autonomous descent and landing, and are being used to checkout landing control algorithms for the next generation of lander missions.

Marshall Experts, Industry, Military and Academia Share Perspectives at Wernher von Braun Memorial Symposium
Discussing NASA's exploration roadmap during an Oct. 25 panel session at the fourth annual Wernher von Braun Memorial Symposium are Deputy Associate Administrator, Exploration Systems Development Division Dan Dumbacher, left; Space Launch System Program Manager Todd May, center; and Orion Mulit-Purpose Crew Vehicle Program Manager Mark Geyer. The event, held at the Chan Auditorium at UAHuntsville Oct. 24-26, featured a report from NASA Headquarters by NASA Associate Administrator Christopher Scolese and an International Space Station update by NASA Associate Administrator for Human Exploration and Operations William Gerstenmaier. Panel topics included energizing commercial space, integrating robotic and human exploration, the National Institute of Rocket Propulsion Systems, military space initiatives and space policy. The symposium was organized by the American Astronautical Society in conjunction with UAHuntsville, the Huntsville National Space Club and the Marshall Space Flight Center. (MSFC/Ray Downward)

Successful Launch Sets Stage for Soyuz Flight
NASA news release
The following is a statement from Bill Gerstenmaier, associate administrator for Human Exploration and Operations at NASA Headquarters, on the Oct. 30 launch of the Progress 45 spacecraft to the International Space Station. The rocket lifted off from the Baikonur Cosmodrome in Kazakhstan at 5:11 a.m. CDT.

"We congratulate our Russian colleagues on Sunday's successful launch of ISS Progress 45, and the spacecraft is on its way to the International Space Station. Pending the outcome of a series of flight readiness meetings in the coming weeks, this successful flight sets the stage for the next Soyuz launch, planned for mid-November. The December Soyuz mission will restore the space station crew size to six and continue normal crew rotations."

Close Encounters of the Galactic Kind
Astronomers have used a large survey to test a prediction that close encounters between galaxies can trigger the rapid growth of supermassive black holes. Key to this work was the Marshall Space Flight Center-managed Chandra X-ray Observatory telescope’s unique ability to pinpoint actively growing black holes through the X-rays they generate.

The researchers looked at 562 pairs of galaxies ranging in distances from about 3 billion to 8 billion light years from Earth. They found that the galaxies in the early stages of an encounter with another were more likely than isolated, or "lonelier" galaxies to have actively growing black holes in their cores.
These two composite images (see photo) show a sample of the pairs of galaxies that are undergoing close encounters in the survey. In these images, the data from the observatory are shown in purple and the Hubble Space Telescope data are in gold. In both images, the point-like X-ray source near the center is generated by gas that has been heated to millions of degrees as it falls toward a supermassive black hole located in the middle of its host galaxy. The other faint X-ray emission may be caused by hot gas associated with the pair of galaxies.
The authors of the study estimate that nearly one-fifth of all moderately active black holes are found in galaxies undergoing the early stages of an interaction. This leaves open the question of what events are responsible for fueling the remaining 80 percent of growing black holes. Some of these may involve the late stages of mergers between two galaxies. Less violent events such as gas falling in from the halo of the galaxy, or the disruption of small satellite galaxies are also likely to play an important role.
The survey used in this research is called the Cosmic Evolution Survey, which covers 2 square degrees on the sky with observations from several major space-based observatories including Chandra and Hubble Space Telescope. Accurate distance information about the galaxies was also derived from optical observations with the European Southern Observatory's Very Large Telescope. The researchers compared a sample of 562 galaxies in pairs with 2,726 solo galaxies to come to their conclusions.
A paper describing this work has been accepted for publication in The Astrophysical Journal. The study was led by John Silverman from the Institute for the Physics and Mathematics of the Universe at the University of Tokyo in Japan. There are 54 co-authors from various institutions around the world.

Marshall Center celebrates Safety & Wellness Day
Former NASA astronaut and space shuttle pilot Robert Crippen visited the Marshall Space Flight Center Oct. 26 as part of the center’s 2011 Safety & Wellness Day events. Crippen spoke to team members in Morris Auditorium about safety in the workplace and about his experiences piloting STS-1, the first shuttle flight, and commanding three subsequent shuttle missions. Other Marshall Safety & Wellness Day events included a 5K run, a health walk and a Health & Safety Expo. Center organizations also held their own safety- and health-related team activities to mark the annual NASA reminder to commit to safety every day -- in the workplace and at home. (Emmett Given/MSFC)

Birmingham, Bessemer Students Have Live 'Space Chat' with Space Station Commander
More than 300 students from Birmingham and Bessemer city schools chatted live with Expedition 29 Commander Mike Fossum as he circled the Earth aboard the International Space Station on Oct. 21.

U.S. Rep. Terri Sewell of Alabama hosted the Expedition 29 in-flight educational event, called “To Infinity and Beyond: A Day with NASA Astronauts,” at George Washington Carver High School in Birmingham. Kindergarten to 12th graders got the opportunity to ask Fossum questions about life, work and research in space. The event was designed to inspire and educate a diverse group of students about careers and opportunities in science, technology, engineering and math, also known as STEM.
