American, Russian Leaving Earth for Year at Space Station

Posted: at 2:46 pm

An American astronaut and Russian cosmonaut will leave Earth this week and move into the International Space Station for an entire year, all in the name of science.

Scott Kelly and Mikhail Kornienko begin their marathon mission with a Soyuz rocket launch from Kazakhstan early Saturday Friday in the U.S. They should arrive at the orbiting outpost six hours later.

It will be NASA's first stab at a one-year spaceflight, a predecessor for Mars expeditions that would last two to three times as long. The Russians are old hands at this, but it's been nearly two decades since a cosmonaut has spent close to a year in orbit.

Five things to know about the duo's extraordinary endeavor:

THE CREW

Both Scott Kelly and Mikhail Kornienko have lived on the space station before. No-nonsense former military men, they were selected as an astronaut and cosmonaut in the 1990s. Kelly, 51, is a retired Navy captain and former space shuttle commander. Kornienko, 54, is a former paratrooper. The pair will blast off with Russian Gennady Padalka, a veteran spaceman who will spend six months at the orbiting lab.

THE MISSION

Kelly and Kornienko will remain on board until next March. During that time, they will undergo extensive medical experiments, and prepare the station for the anticipated 2017 arrival of new U.S. commercial crew capsules. That means a series of spacewalks for Kelly. They also will oversee the comings and goings of numerous cargo ships, as well as other Russian-launched crews. Soprano superstar Sarah Brightman will stop by as a space tourist in September.

THE SCIENCE

Doctors are eager to learn what happens to Kelly and Kornienko once they surpass the usual six-month stay for space station residents. Bones and muscles weaken in weightlessness, as does the immune system. Body fluids also shift into the head when gravity is absent, and that puts pressure on the brain and the eyes, impairing vision for some astronauts in space. Might these afflictions peter out after six months, hold steady or ramp up? That's what researchers want to find out so they can protect Mars-bound crews in the decades ahead.

Russia to resume space tourism in 2018

Russia officials say they will resume space tourism in 2018 after years of sending into space only professional cosmonauts and astronauts.

Russia had sent seven paying guests to the International Space Station since 2001 before curtailing the program in 2009. Sending a tourist has been all but impossible since 2011 when the United States shut down its Space Shuttle program and had to rely on Russian Soyuz rockets in order to get into orbit.

Russia, however, has made an exception for British soprano Sarah Brightman who is due to blast off on Sept. 1.

American enterprises aimed at space tourism were stymied last fall after a Virgin Galactic craft crashed during a test flight over the Mojave desert. The SpaceShipTwo crash, on Oct. 31, 2014, killed one pilot and left another injured. It also slowed Virgin Galactic founder Richard Branson's plans of getting paying customers to the edges of space, for $250,000 a pop.

Virgin Galactic CEO said soon after the incident that the company could resume test flights this summer.

Russia's RKK Energia, a state-controlled rocket manufacturer, said in a quarterly report released on Tuesday that it plans to make up for an expected drop in demand for manned flights by resuming space tourism in 2018.

In Mars One we trust

Posted: at 2:46 pm

Mars One promises to send humans on a one-way trip to the red planet, with the intent to colonize, by 2027. Once the first four people leave Earth for Mars, there's no turning back, no panic button, no chance to return home. This aspect of the trip isn't just for drama -- it's a core tenet of Mars One's technical feasibility. CEO Bas Lansdorp believes that it's possible, using current technology, to land and sustain human life on Mars.

But the systems that would power a human settlement on an alien planet are ridiculously complex. They're so complicated that Lansdorp isn't yet sure what they will actually be. This lack of ready research has mired Mars One in controversy, thanks to a recent one-two credibility punch: First, a 2014 research paper from the Massachusetts Institute of Technology concludes that the program is not realistic. Second, a series of articles for Matter magazine calls into question the feasibility of Mars One financially, scientifically and ethically. Still, Lansdorp promises to send humans to live on Mars, but he can't yet say how. He wants the world to trust him.

Mars One plans to send four people to Mars in 12 years, with the intent to launch subsequent manned missions and colonize the planet. Its Technical Feasibility section promises that the mission is possible using "existing, validated and available technology." Lansdorp places his faith completely in the companies that will build the necessary systems; Mars One won't manufacture any hardware itself.

Lansdorp, who founded his own wind-energy company in 2008, freely admits he doesn't understand the scientific details behind Mars One's proposals. "On a high level, yes. On a detailed level, absolutely not. I'm a mechanical engineer, so I know about the scientific principles in general," he says.

This is one reason Mars One will outsource all technological work: Currently, Paragon Space Development Corporation is working on Mars One's life-support systems. Paragon is preparing a report on the technical aspects of life on Mars, due out before the end of April. This will be Mars One's first attempt at explaining the dense science behind its space-survival concepts.

But for now, Mars One makes huge, impossible-sounding claims, but doesn't offer answers to technical questions, which is one reason MIT dove in itself.

"The Mars One mission plan, as described on their website and by Mr. Lansdorp on several occasions, is not feasible," write Sydney Do and Andrew Owens, the researchers behind the MIT study. They argue that Mars One's technological conceit is simply not viable. "Significant technology development is required before we can even land and sustain humans on Mars, much less support a growing colony," they say.

Mount Sinai Researchers Discover Genetic Origins of Myelodysplastic Syndrome Using Stem Cells

Newswise (New York March 25, 2015) Induced pluripotent stem cells (iPSCs)adult cells reprogrammed back to an embryonic stem cell-like statemay better model the genetic contributions to each patient's particular disease. In a process called cellular reprogramming, researchers at Icahn School of Medicine at Mount Sinai have taken mature blood cells from patients with myelodysplastic syndrome (MDS) and reprogrammed them back into iPSCs to study the genetic origins of this rare blood cancer. The results appear in an upcoming issue of Nature Biotechnology.

In MDS, genetic mutations in the bone marrow stem cell cause the number and quality of blood-forming cells to decline irreversibly, further impairing blood production. Patients with MDS can develop severe anemia and in some cases leukemia also known as AML. But which genetic mutations are the critical ones causing this disease?

In this study, researchers took cells from patients with blood cancer MDS and turned them into stem cells to study the deletions of human chromosome 7 often associated with this disease.

With this approach, we were able to pinpoint a region on chromosome 7 that is critical and were able to identify candidate genes residing there that may cause this disease, said lead researcher Eirini Papapetrou, MD, PhD, Department of Oncological Sciences, Icahn School of Medicine at Mount Sinai.

Chromosomal deletions are difficult to study with existing tools because they contain a large number of genes, making it hard to pinpoint the critical ones causing cancer. Chromosome 7 deletion is a characteristic cellular abnormality in MDS and is well-recognized for decades as a marker of unfavorable prognosis. However, the role of this deletion in the development of the disease remained unclear going into this study.

Understanding the role of specific chromosomal deletions in cancers requires determining if a deletion has observable consequences as well as identifying which specific genetic elements are critically lost. Researchers used cellular reprogramming and genome engineering to dissect the loss of chromosome 7. The methods used in this study for engineering deletions can enable studies of the consequences of alterations in genes in human cells.

Genetic engineering of human stem cells has not been used for disease-associated genomic deletions, said Dr. Papapetrou. This work sheds new light on how blood cancer develops and also provides a new approach that can be used to study chromosomal deletions associated with a variety of human cancers, neurological and developmental diseases.

Reprogramming MDS cells could provide a powerful tool to dissect the architecture and evolution of this disease and to link the genetic make-up of MDS cells to characteristics and traits of these cells. Further dissecting the MDS stem cells at the molecular level could provide insights into the origins and development of MDS and other blood cancers. Moreover, this work could provide a platform to test and discover new treatments for these diseases.
