U.S. space shuttle spawned heart pump, fly by wire

As the United States prepares to end its space shuttle program, technologies developed to nurture the reusable spaceships through three decades of flight will live on in day-to-day use on Earth.

Shuttle Atlantis and its four-member crew are due back at the Kennedy Space Center in Florida at 5:57 a.m. EDT on Thursday after a mission to resupply the International Space Station, a $100 billion project of 16 nations, currently orbiting about 250 miles above the planet.

NASA points to the station, finished this year after 12 years of assembly by shuttle crews, as the program’s crowning achievement, but it is far from the only one.

“Space shuttle has provided unbelievable benefit and return on the investment of the American taxpayer,” said NASA deputy administrator Lori Garver.

That investment, including development and operational costs over the past 40 years, tallies about $200 billion, according to a recent University of Colorado study.

The shuttle program also took a toll in human life, with 14 astronauts killed in two separate accidents…… Continue reading U.S. space shuttle spawned heart pump, fly by wire

This never-before-seen view of the International Space Station shows the orbiting lab as it appeared to astronauts on the shuttle Atlantis after the two spacecraft undocked for the final time on July 19, 2011 during NASA's final shuttle mission. The station rotated 90 degrees after undocking in an unprecedented manuever to provide better views to the shuttle crew.

An Amazing View

This panoramic view was photographed from the International Space Station toward Earth, looking past space shuttle Atlantis’ docked cargo bay and part of the station, including a solar array panel.

The photo was taken as the joint complex passed over the southern hemisphere. Aurora Australis or the Southern Lights can be seen on Earth’s horizon and a number of stars also are visible.

Yeast Rising to the Space Station

Chefs across the globe may not know it yet, but their baker’s yeast just left the kitchen and blasted off into low Earth orbit. Hitching a ride on the space shuttle Atlantis on July 8, 2011, the samples will be grown on the International Space Station as part of the Genotypic and Phenotypic Changes in Yeast Related to Selective Growth Pressures Unique to Microgravity or Micro-4 investigation. Capable of raising more than just breads, this useful organism will help researchers better understand the impact of the space environment on live cells in humans.

This yeast — S. cerevisiae — has been of use since the ancient Egyptians first figured out how to harness it for wine and bread making. In modern times it is still used for baking and was the first organism to have its genome fully sequenced. Scientists hope that by studying the changes of yeast in microgravity, they will better understand the changes human cells may experience during long-duration spaceflight. Gaining better knowledge of genetic alterations by studying yeast growth during this microgravity research may also help in understanding how these changes could manifest in human disease here on Earth.

This investigation is a collaboration with BioServe Space Technologies, Durham Veterans Affairs Medical Center, and the University of Toronto. According to Michael Costanzo, Ph.D. and one of the co-investigators for Micro-4 at the University of Toronto, the similarities between human cells and the yeast’s genetic makeup makes it ideal for study in space. “We are examining which genes are important for cell growth and survival in a zero gravity environment. The results of our ‘yeastnaut’ experiments may provide insight into which set of human genes are important and how these genes work together to help organisms/humans deal with extreme environments associated with space travel — such as zero-gravity and elevated radiation.”….

Bees, frogs, monkeys and jellyfish… the weird and wonderful creatures that joined Nasa’s shuttle programme over the years

With the final lift-off in Nasa’s space shuttle programme only hours away, weather permitting, people across the world are turning their attention to what has been a remarkable 30 years.
Most of the focus is be on the scientific achievements and tragic loss of 14 lives in the Challenger and Columbia disasters.
But it wasn’t just human astronauts who boarded the shuttles.

In September 1992, Nasa scientists sent female frogs into space aboard Endeavour. They wanted to determine if reproduction and development occur normally in microgravity, so half the frogs eggs laid were placed in microgravity and the other half in normal gravity. All tadpoles returned to Earth in a healthy condition, but those raised in microgravity drowned because they didn't have a sense of up and down so were unable to take their first breaths on the water's surface

Many different animals have gone along for the ride too, to help mankind discover how life can adapt, or not, in space.
Among those to have made the journey are jellyfish, rats, frogs, tadpoles and honeybees.
This final journey will also be taking 30 mice to test the effect of zero gravity on bones. The findings could prove beneficial for both astronauts and osteoporosis sufferers.
Nasa’s first space shuttle flight was in April 1981; the 135th and final launch is set for today.
Now seems like the perfect time to raise a glass to these equally intrepid explorers.
