AIP FYI: International Space Station to be Extended Until 2024; Asteroid Mission Reaffirmed

Posted: at 3:44 pm

We are pleased to announce that the Obama Administration has approved an extension of the International Space Station (ISS) until at least 2024,wrote Office of Science and Technology Policy Director John Holdren and NASA Administrator Charles Bolden earlier this month. This announcement extends the station for four additional years beyond its previous schedule.

In hisstatementand in a speech at the International Space Exploration Forum at the U.S. Department of State, Holdren outlined the benefits of research on the station and the four year extension. He said the station is critical as a research laboratory for a human mission to Mars in the 2030s. NASA has identified 32 human-health risks likely to be encountered on long-duration flights. Research conducted on the station is necessary to mitigate fully 21 of these risks, he said. Holdren also described medical and other societal benefits from station research. Extension of the ISS will require more commercial cargo and crew flights to the station. This should, to some extent, reduce doubts that some Members of Congress have expressed about whether commercial providers would be willing to undertake robust development of servicing hardware for only a few years. The extension will, Holdren predicted, reduce the per flight cost of servicing the station, and make this investment even more attractive. He also spoke of the stations importance to Earth science research and its role in fostering international cooperation.

Bolden reiterated Holdrens statements about the station in his comments to the forum:From a NASA perspective the ISS is absolutely essential to the goals of sending humans to Mars in the 2030s, developing and establishing a robust U.S. crew transportation capability to low Earth orbit, achieving a self-sustaining commercial use of space in LEO, and returning benefits to humanity through research and technology development.

The Ranking Member of the House Science, Space, and Technology Committee, Eddie Bernice Johnson (D-TX), released the following statement regarding the station extension: I am pleased that the Administration is initiating an important dialogue with its international partners on the extension of ISS operations to at least 2024. The ISS has been a critical element of our nations human space exploration program, and it is important that a decision on its potential extended operations be made in a way that enables NASA and its partners to ensure its effective utilization and operation. I look forward to further details on the Administrations proposal and on the planned priorities and objectives for ISS activities during the proposed extension.

Holdren and Bolden both reiterated their support for the proposed Asteroid Redirect Mission to retrieve a near-Earth asteroid and put it into orbit at the L2 gravitational-equilibration point where it would be visited by astronauts. Holdren described this mission as one that will significantly raise the bar for what humans could accomplish in space.

Funding for the International Space Station is provided through NASAs Space Operations budget. The FY 2014 request was $3,882.9 million, of which $3,049.1 million or 79 percent was for the station (the remainder being for Space and Flight Support.) The FY 2014 appropriation for Space Operations is $3,778.0 million, approximately 97 percent of the request. The agreement maintains strong support for the ISS declared the Explanatory Statement accompanying the bill.

Congress has been much less enthusiastic about the asteroid mission. The FY 2014 Explanatory Statement included this passage:NASA has proposed a new mission known as the ARM that would engage both scientific and human exploration activities. While the ARM is still an emerging concept, NASA has not provided Congress with satisfactory justification materialssuch as detailed cost estimates or impacts to ongoing missions. The completion of significantpreliminary activities is needed to appropriately lay the groundwork for the ARM prior to NASAand Congress making a long-term commitment to this mission concept.

Space station ‘farm’ successfully grows a variety of crops

Posted: at 3:44 pm

MOSCOW, Jan. 31 (UPI) -- A variety of crops successfully grown and harvested on the International Space Station have been verified as safe to eat, a Russian scientist says.

Space-based agriculture has long been of interest, as plants not only scrub carbon dioxide exhaled by astronauts but could be a renewable food source, scientists have said.

"The experiments with peas have been very promising," Margarita Levinskikh, a researcher at the Institute of Biomedical Problems, told an annual space conference in Moscow in describing the ISS "farming."

Russian cosmonauts have grown Japanese leafy greens and a variety of dwarf wheat that has produced seeds of "just extraordinary quality," RIA Novosti quoted her as saying.

Russian cosmonauts will sow rice, tomatoes and bell peppers in the station's Lada greenhouse next year, she said, a cooperative effort between the institute and the Space Dynamics Laboratory at Utah State University.

Currently all food onboard the space station is flown there on periodic resupply missions. Long-duration deep space missions without agriculture would require many months' or years' worth of food, greatly adding to their launch weight, the institute said.

NASA announces funding for space station physics research

Posted: at 3:44 pm

PASADENA, Calif., Jan. 31 (UPI) -- NASA says it will fund seven proposals for physics research using its new microgravity laboratory, set to launch to the International Space Station in 2016.

The Cold Atom Laboratory will provide an opportunity to study ultra-cold quantum gases in the microgravity environment of the space station, a frontier in scientific research expected to reveal interesting and novel quantum phenomena, the space agency said Thursday.

Operating experiments in space makes it possible to conduct research in a way unachievable on Earth because atoms can be observed over a longer period and mixtures of different atoms can be studied free of the effects of gravity, where cold atoms can be trapped more easily by magnetic fields, it said.

The chosen proposals came from seven research teams, which include three Nobel laureates, in response to NASA's research announcement "Research Opportunities in Fundamental Physics." The proposals will receive a total of about $12.7 million over a four- to five-year period and development of selected experiments will begin immediately, the agency said.

The Cold Atom Laboratory is a joint partnership of three NASA branches; the Jet Propulsion Laboratory in Pasadena, Calif., the International Space Station Program Office at the Johnson Space Center in Houston and the Space Life and Physical Sciences Branch at NASA Headquarters in Washington.

Running with genetic scissors: how a breakthrough technology works

News Release

Short DNA sequences known as PAM (shown in yellow) enable the bacterial enzyme Cas9 to identify and degrade foreign DNA, as well as induce site-specific genetic changes in animal and plant cells. The presence of PAM is also required to activate the Cas9 enzyme. (Illustration by KC Roeyer.)

A central question has been answered regarding a protein that plays an essential role in the bacterial immune system and is fast becoming a valuable tool for genetic engineering. A team of researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have determined how the bacterial enzyme known as Cas9, guided by RNA, is able to identify and degrade foreign DNA during viral infections, as well as induce site-specific genetic changes in animal and plant cells. Through a combination of single-molecule imaging and bulk biochemical experiments, the research team has shown that the genome-editing ability of Cas9 is made possible by the presence of short DNA sequences known as PAM, for protospacer adjacent motif.

Our results reveal two major functions of the PAM that explain why it is so critical to the ability of Cas9 to target and cleave DNA sequences matching the guide RNA, says Jennifer Doudna, the biochemist who led this study. The presence of the PAM adjacent to target sites in foreign DNA and its absence from those targets in the host genome enables Cas9 to precisely discriminate between non-self DNA that must be degraded and self DNA that may be almost identical. The presence of the PAM is also required to activate the Cas9 enzyme.

With genetically engineered microorganisms, such as bacteria and fungi, playing an increasing role in the green chemistry production of valuable chemical products including therapeutic drugs, advanced biofuels and biodegradable plastics from renewables, Cas9 is emerging as an important genome-editing tool for practitioners of synthetic biology.

Understanding how Cas9 is able to locate specific 20-base-pair target sequences within genomes that are millions to billions of base pairs long may enable improvements to gene targeting and genome editing efforts in bacteria and other types of cells, says Doudna who holds joint appointments with Berkeley Labs Physical Biosciences Division and UC Berkeleys Department of Molecular and Cell Biology and Department of Chemistry, and is also an investigator with the Howard Hughes Medical Institute (HHMI).

Doudna is one of two corresponding authors of a paper describing this research in the journal Nature. The paper is titled DNA interrogation by the CRISPR RNA-guided endonuclease Cas9. The other corresponding author is Eric Greene of Columbia University. Co-authoring this paper were Samuel Sternberg, Sy Redding and Martin Jinek.

Bacterial microbes face a never-ending onslaught from viruses and invasive snippets of nucleic acid known as plasmids. To survive, the microbes deploy an adaptive nucleic acid-based immune system that revolves around a genetic element known as CRISPR, which stands for Clustered Regularly Interspaced Short Palindromic Repeats. Through the combination of CRISPRs and RNA-guided endonucleases, such as Cas9, (Cas stands for CRISPR-associated), bacteria are able to utilize small customized crRNA molecules (for CRISPR RNA) to guide the targeting and degradation of matching DNA sequences in invading viruses and plasmids to prevent them from replicating. There are three distinct types of CRISPRCas immunity systems. Doudna and her research group have focused on the Type II system which relies exclusively upon RNA-programmed Cas9 to cleave double-stranded DNA at target sites.

What has been a major puzzle in the CRISPRCas field is how Cas9 and similar RNA-guided complexes locate and recognize matching DNA targets in the context of an entire genome, the classic needle in a haystack problem, says Samuel Sternberg, lead author of the Nature paper and a member of Doudnas research group. All of the scientists who are developing RNA-programmable Cas9 for genome engineering are relying on its ability to target unique 20-base-pair long sequences inside the cell. However, if Cas9 were to just blindly bind DNA at random sites across a genome until colliding with its target, the process would be incredibly time-consuming and probably too inefficient to be effective for bacterial immunity, or as a tool for genome engineers. Our study shows that Cas9 confines its search by first looking for PAM sequences. This accelerates the rate at which the target can be located, and minimizes the time spent interrogating non-target DNA sites.
