NASA expects to pay an average of $58 million a seat when its astronauts begin flying on Boeing's CST-100 and SpaceX's Dragon capsules in 2017, Kathy Lueders, manager of NASA's Commercial Crew program, told reporters during a news conference in Houston and via conference call.
"I don't ever want to have to write another check to Roscosmos after 2017, hopefully,'' NASA Administrator Charles Bolden said.
Both SpaceX and Boeing plan two test flights to the station, the first without a crew and the second with a combination of company test pilots and NASA astronauts aboard.
SpaceX is targeting its unmanned test flight in 2016 and its piloted flight in early 2017, said company president Gwynne Shotwell.

Boeing's test flights are targeted for April and July 2017, vice president and program manager John Elbon said.
For its manned test flight, Boeing plans to fly one as-yet-unnamed company astronaut and one NASA astronaut. SpaceX said it is still deciding on a test flight crew.
Though schedules show SpaceX being ready ahead of Boeing to fly operational missions, NASA currently expects Boeing to begin flight services first in December 2017, Lueders said.

NASA may send a helicopter drone to Mars in 2020 to accompany a six-wheeled land vehicle.
NASA may send a helicopter drone to Mars in 2020 to accompany a six-wheeled land vehicle being designed for the space agency's next rover mission.
The drone, being developed at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., weighs 2.2 pounds and sports helicopter blades measuring 3.6 feet from tip to tip, according to Space.com.
JPL has released a video exploring the idea of using a drone on Mars, which you can see below.
"If our rover was equipped with its very own helicopter that could see over tall objects in front of it, it would allow us to make decisions much more efficiently on which way to command the rover," JPL mechanical engineer Mike Meacham said in the video.
Challenges facing the design team include the difficulty of flying in the thin, almost nonexistent atmosphere of Mars, which would require a different copter design than the ones that fly with ease on Earth. The body of the Mars drone must be relatively lightweight compared to a bulkier blade system to achieve lift in an atmosphere that's just 1 percent as dense as Earth's.
The drone would probably only be capable of three-minute flights, according to Bob Balaram, chief engineer of mobility and robotics systems at JPL. It would climb to a maximum height of 330 feet and fly a few thousand feet over land each day.
"It has to be autonomous in terms of being able to fly and maintain stable flight," Balaram said in the video. "And then, this system has to repeatedly take off and land on natural rocky terrain like you see out here. And then, the other one is that it has to survive the harsh environment of Mars."
The proposed copter would include "counter-rotating propellers designed for use in the thin Martian air; batteries that are recharged by solar power; a high-resolution, downward-looking camera for navigation, landing and science surveying of the terrain; and a communications system to relay data to the rover," Space.com reported.
The site noted that an insect-like "entomopter" flying device has also been proposed for a future Mars mission, while balloons are another aerial reconnaissance idea engineers are developing for exploring the Red Planet.

New details about NASA's Commercial Crew Program were revealed today during a press conference held at the Johnson Space Center in Houston. Both SpaceX and Boeing have completed the first milestones in their plans to send humans into space from US soil for the first time in years.
SpaceX has completed the first certification milestone in its CCP commitment, and will spend much of 2015 testing abort solutions for its formerly cargo-only Dragon capsule. (Abort procedures are more critical in crewed missions.) A launchpad abort will be tested in the next two months at Cape Canaveral, and an in-flight abort test will follow "later this year," according to SpaceX President and COO Gwynne Shotwell. Uncrewed missions to the ISS with the new capsule will start in 2016, and the company is still working out the makeup of its first test flight crew.
"I don't ever want to have to write another check to Roscosmos."
The CCP was started after the shuttle program was put to rest in 2011. Last April, NASA announced it wouldn't work with Russia any longer when it came to transporting American astronauts to the International Space Station. Instead, NASA awarded contracts to SpaceX and Boeing to build this new fleet of crewed spacecraft back in September. "I don't ever want to have to write another check to Roscosmos," NASA's administrator Charles Bolden said during today's press conference. As of right now, the CCP should allow for an average cost of $58 million per seat, as opposed to the average of $70 million per seat it was costing the agency to fly with the Russians.
SpaceX's goal is to fly over 50 Falcon 9 missions before attempting the first crewed launch in early 2017. Those missions will accommodate four crew members with space for cargo. The company will operate these CCP missions similarly to its cargo missions. That means the mission control centers, flight simulators, and other flight capabilities will be located at both Johnson Space Center and at the company's base in Hawthorne, CA.
The company is also working on outfitting its Dragon capsule with propulsive landing, Shotwell said, which could improve reusability by dispensing with the need to splash down in water. Instead, the capsule would land right at Johnson Space Center, using rockets on the bottom to help control the descent. That's not the only new technology the company is working on. It hopes to outfit its Falcon 9 rockets with wings and retrorockets so they can land on autonomous barges in the ocean.
Boeing will launch the first crewed mission
Commercial Crew Program Manager Kathy Lueders said that the first crewed mission in 2017 will belong to Boeing despite the fact that SpaceX already has a working spacecraft. To fill that first mission, the astronaut office is looking at naming a "small cadre" of astronauts that would follow both companies. The first crew will be selected from that group, which will be named "before long," according to Johnson Space Center director Ellen Ochoa.
Boeing has completed the first two certification milestones for its CST-100 spacecraft. NASA has signed off on parts of its commercial crew operation, including designs for the control center, training systems, flight simulators, and software. Boeing has also started building its crew access tower on the Atlas V launchpad, and that construction will continue in between uncrewed Atlas V launches.

SpaceX and Boeing are on their way to launching US astronauts, NASA says
Boeing will be the first commercial company to carry a NASA astronaut to space in July 2017 under a contract with the US space agency, followed by its competitor SpaceX.
NASA is funnelling billions of dollars to both companies so that they can replace American access to the orbiting International Space Station after the US space shuttle program was retired in 2011.
The announcement of US$4.2 billion for Boeing and US$2.6 billion for SpaceX was made in September 2014.
However, a legal challenge by Sierra Nevada - which was developing a space-shuttle-like vehicle called Dream Chaser and was closed out of the competition - meant that officials could not reveal many details until now.
The US Government Accountability Office denied the protest by Sierra Nevada earlier this month, allowing NASA and its partners to speak publicly about the contracts and future plans for test flights.
Commercial crew program manager Kathy Lueders said at a press conference in Houston, Texas that Boeing would be the first to make two contracted missions to carry NASA astronauts, since it has completed two milestones so far, and SpaceX just one.
"Our goal is to have two robust providers," Lueders added.
A NASA astronaut and a Boeing test pilot will make the first crewed test flight on the spacecraft called Crew Space Transportation-100, or CST-100 for short, in July 2017, said John Elbon, Boeing's vice president and general manager of space exploration.
"The first services mission then will begin in December of '17," he told reporters, referring to the first official trip to the International Space Station with crew on board.
SpaceX's upgraded Dragon crew vehicle is on track for an unmanned test flight in 2016, followed by a test flight including crew on board in early 2017, said vice-president Gwynne Shotwell, who did not give specific dates.

American spacecraft systems testing followed by increasingly complex flight tests and ultimately astronauts flying orbital flights will pave the way to operational missions during the next few years to the International Space Station.
Those were the plans laid out Monday by NASA's Commercial Crew Program officials and partners as they focus on developing safe, reliable and cost-effective spacecraft and systems that will take astronauts to the station from American launch complexes.
According to Boeing, the company's schedule calls for a pad abort test in February 2017, followed by an uncrewed flight test in April 2017, then a flight with a Boeing test pilot and a NASA astronaut in July 2017.
SpaceX said they anticipate a pad abort test in about a month, then an in-flight abort test later this year as part of its previous development phase. An uncrewed flight test is planned for late 2016 and a crewed flight test in early 2017.
Speaking for the first time together since the awarding of the final development and certification contracts, officials from NASA's Commercial Crew Program, Boeing and SpaceX revealed some of the details of their plans to cross the chasm from spacecraft and launch system design to flight tests, certification and operational missions to the station.
"It's an incredible testament to American ingenuity and know-how, and an extraordinary validation of the vision we laid out just a few years ago as we prepared for the long-planned retirement of the space shuttle," said Charlie Bolden, NASA administrator, during the briefing at the agency's Johnson Space Center in Houston.
"This work is part of a vital strategy to equip our nation with the technologies for the future and inspire a new generation of explorers to take the next giant leap for America."
Boeing and SpaceX were selected in September 2014 to finalize their respective CST-100 and Crew Dragon spacecraft along with the rockets that will lift them into orbit and all of the ground and mission operations networks essential for safe flights. Both companies have worked with NASA's Commercial Crew Program throughout multiple development phases, continuing to advance their designs before being chosen to complete their systems, reach certification and then fly astronauts to the station.
The goal of NASA's effort is to provide an American launch vehicle and spacecraft capable of safely carrying astronauts to the station. Unlike other NASA spacecraft, though, this new generation of human-rated vehicles will be designed, built, operated and owned by the companies themselves, not NASA.
NASA will buy space transportation services from the companies for astronauts and powered cargo. It will be an arrangement like the one the agency uses already with the Commercial Resupply Services initiative that uses privately developed and operated rockets and spacecraft to deliver critical cargo to the station.

Reston, Va. (January 27, 2015) - A novel radioguided surgery technique could quickly and effectively identify residual cancer cells during brain tumor surgery, with low radiation exposure for both patients and surgeons. The study, featured in the January 2015 issue of the Journal of Nuclear Medicine, reports that Y-90 DOTATOC, a beta-minus-emitting tracer, can effectively delineate the margins of meningiomas and high-grade gliomas.
Radioguided surgery (RGS) allows the surgeon to evaluate the completeness of a tumor resection while minimizing the amount of healthy tissue removed. During the procedure, a surgeon is provided with vital and real-time information on the location and extent of the lesion that allows better assessment of the resection margins. The technique uses a radiolabeled tracer preferentially taken up by the tumor to discriminate cancerous tissue from healthy organs, as well as a probe sensitive to the emission released by the tracer, to identify in real time the targeted tumor focus. The radiopharmaceutical is administered to the patient before surgery.
"This research relates to a completely innovative radioguided surgery technique: the use of a beta-minus-emitting tracer," states lead researcher Riccardo Faccini. "This is a change in paradigm because RGS currently uses only gamma and beta-plus-emitting isotopes. The new technique uses Y-90-labeled DOTATOC--a tracer that traditionally is used for molecular radiotherapy--for diagnostic purposes."
In the study, uptake and background from healthy tissues were estimated on Ga-68 DOTATOC positron emission tomography (PET) scans of 11 meningioma patients and 12 high grade glioma (HGG) patients. A dedicated statistical analysis of the images was completed and validated. The feasibility study was performed using full simulation of emission and detection of the radiation, accounting for the measured uptake and background rate. All meningioma patients but one, who had an atypical extracranial tumor, showed high uptake of DOTATOC. Uptake of Y-90 DOTATOC in meningiomas was high in all studied patients. Uptake in HGGs was lower than in meningiomas but was still acceptable for RGS. Funding for the study was provided by Italian institutions Universita' di Roma La Sapienza, Istituto Nazionale di Fisica Nucleare, Istituto Italiano di Tecnologia, Centro Fermi Museo Storico della Fisica, and Istituto Europeo di Oncologia.
"We are setting up clinical tests of RGS with beta-minus radiation on meningiomas, based on their known high receptivity for DOTATOC," Faccini said. "This study suggests that the next step will be to try the technique on gliomas, which will be more challenging, but feasible and definitely clinically interesting. In parallel with this technique, we are also developing a surgical probe customized for the problem, which could in the future extend the applicability of the method to endoscopy or laparoscopy."
Meningiomas are tumors that grow on the delicate outer covering of the brain. According to the Brain Science Foundation, meningiomas account for approximately 33.8% of all primary brain tumors, making them the most common type. Gliomas, which are malignant tumors that commonly invade adjacent tissue and spread through the central nervous system, represent about 17.1% of all primary brain tumors and about 70.5% of all astrocytomas.
