NASA is expanding its existing capabilities for doing plant and animal tissue investigations on the International Space Station with the delivery of a new centrifuge scheduled for this summer. The centrifuge is a NASA and commercial industry collaboration, and will be housed in the NanoRacks facility.
The small Gravitational Biology Lab will allow biological experimentation in artificial gravity -- from zero gravity to twice Earth’s normal gravity -- for prolonged periods of time. The new facility will provide environmental control, lighting, data transfer, commanding, and observation of experiments in Mars and moon gravity conditions, as well as mimicking Earth's gravity. This is useful for biological research, and could lead to advances in medications and vaccines, agricultural controls, and discoveries in genetics -- all beneficial to those of us on Earth.

WASHINGTON — NASA is banking on its Commercial Crew Program to increase international space station (ISS) crew capacity to seven from the current six — something that could happen as soon as 2017 if Congress is willing to dramatically increase the program’s budget, the agency’s top human spaceflight official said.
“We would definitely increase the crew size on ISS to seven crew members,” William Gerstenmaier, associate administrator for NASA’s Human Exploration and Operations Mission Directorate said June 20 during a hearing before the Senate Commerce science and space subcommittee. “We think that will increase the research capability onboard station and allow us to do more national lab research and be more effective in utilizing space station.”
To do that, and to ensure that the privately operated astronaut taxis NASA is helping industry develop are flying by 2017, the Commercial Crew Program will need more than $800 million in annual funding from 2014 to 2017. Congress gave the program $406 million for 2012, less than half what NASA requested. The program is poised to fare somewhat better in 2013, with key lawmakers pledging $525 million of the $830 million the agency requested.
NASA currently pays the Russian space agency, Roscosmos, about $60 million a seat to ferry crew members to the international space station aboard Soyuz spacecraft. The U.S. companies competing to develop a domestic alternative to Soyuz are expected to beat that price, Gerstenmaier said.
“We expect there to be a cost reduction, but I think it’s a little too early for us to pick a particular value for a cost reduction,” Gerstenamier said. He added that NASA plans to buy seats on two commercial crew flights a year. The agency would book four seats on each flight, he said.

HOUSTON — NASA and Canadian Space Agency (CSA) ground control teams combined efforts June 19-20 to begin the second phase of a robotic refueling demonstration outside the International Space Station, a pioneering effort to establish engineering strategies for extending the operating lives of aging satellites.
The three-day second phase of the two-year, $22.6 million Robotic Refueling Mission (RRM) employes the 58-ft.-long Canadarm2; Canada’s Special Purpose Dextrous Manipulator (Dextre), a two-armed, 11.5-ft.-long robotic handyman; and the Goddard Space Flight Center’s satellite simulator, an engineering demonstrator delivered and installed on the station’s long solar power truss by the crew of NASA’s final shuttle mission, STS-135, in July 2011.
The washing machine-sized demonstrator serves as a 3-D task board and tool storage device. The development effort features refueling techniques for satellites not initially designed to be refueled in orbit.
Working without the station’s six-member crew, ground control teams at St. Hubert, Quebec, and NASA’s Mission Control in Houston placed Dextre in the grasp of the larger robot arm for the first of three overnight sessions.
During the first session, Dextre pulled a multifunction tool from the Goddard demonstrator to remove and store a two-way T-valve. In similar fashion, Dextre will wield adapter tools to remove a gas cap from the demonstrator and simulate the penetration of the fuel tank seal installed prior to most satellite launches.
The first phase of the RRM demo was successfully carried out in March, with Canadarm2 and Dextre again responding to joint NASA and CSA commands for the checkout and activation of the Goddard demonstrators’s safety cap removal, wire cutter and multifunction tools. The three-day exercise simulated the release of launch locks on tool adapters and the severing of lock wires of the type used to close out fuel and coolant valve fittings on many satellites.
The final phase of the refueling mission demonstration is currently scheduled for later this year. Ground controllers will use the Canadarm2 and Dextre to demonstrate the manipulation of the thermal blankets that jacket satellites, electrical cap extraction and actual refueling. The satellite simulator is equipped with a nozzle tool, a half-gallon of ethanol fuel and a test fuel reservoir for the transfer task that will mark the third phase of the engineering test.

Space officials confirmed on Friday the line-up of a new mission to the International Space Station (ISS) ahead of their launch next month.
Three Expedition 32 crew members - NASA astronaut Suni Williams, cosmonaut Yury Malenchenko and Japanese astronaut Aki Hoshide - are scheduled to launch aboard the Soyuz TMA-05M from the Baikonur Space Center in Kazakhstan on July 15, said a spokesman for the Gagarin Cosmonaut Training Center in Star City, outside Moscow.
The trio has been passing tests at the facility.
They will join Expedition 31's NASA astrounaut Joe Acaba and cosmonauts Gennady Padalka and Sergei Revin on board the orbiting outpost.
Meanwhile, fellow Expedition 31 members cosmonaut Oleg Kononenko and NASA's Don Pettit and Andre Kuipers are preparing for their July 1 return to Earth.
A back-up ISS crew was also confirmed on Friday. It includes Canadian astronaut Chris Hadfield, NASA astronaut Tom Marshburn and cosmonaut Roman Romanenko.

Russian cosmonauts will conduct a space walk in August during which they will install additional anti-meteorite panels on the International Space Station (ISS), cosmonaut Yury Malanchenko said on Friday.
Malanchenko, his U.S. and Japanese colleagues, Sunita Williams and Hoshide Akihiko, are scheduled to depart for a space mission on July 15.
“We will have a space walk in August, which I will conduct together with [Russian cosmonaut] Gennady Padalka,” Malanchenko told journalists in Star City near Moscow, where Russian cosmonauts live and train.
“We will have to move a cargo platform so as to use it more conveniently in the future. We will also install meteorite protection panels [on the ISS],” he said, adding that the space walk will last six hours.

ESA astronaut André Kuipers is scheduled to leave the International Space Station and land on 1 July. André is finishing experiments and packing his bags ready for departure. One of the last experiments is looking at how a human body stays warm.

NASA completed another successful round of Robotic Refueling Mission (RRM) operations on the International Space Station with the Canadian Dextre robot and RRM tools, leaving the RRM module poised for the highly-anticipated refueling demonstration scheduled for late summer 2012.
