Russia to abandon Manned Space Station in 2020

Man in orbit might become history after 2020, as Russia sees no need to keep the ISS operating, announced Vice Prime Minister Dmitry Rogozin. Manned flights make little profit for Russia's space agency, which might focus on other projects.

Russia's Roskosmos space corporation gets little commercial payback from the International Space Station despite spending up to 30 percent of its annual budget on the project, said Rogozin, who is also responsible for the defence industry.

"Our profit is flat low... so we see no business interest in it [going on with the ISS]. Would there be other commercial proposals [we'd consider them]," Rogozin said.

"There are rumors about Russia leaving the ISS project. We will not, the program is set to run until 2020 and we will stick to our international obligations. As for prolonging it till 2024 - that's what we are really doubtful of," Rogozin stressed.

"Simply circling the earth's orbit and earning something on cosmonaut delivery to space - that's not enough for this great space country [Russia]," Rogozin said, adding that Roskosmos needs an innovative space exploration plan that would imply a technological breakthrough from the technologies of the last century.

Roskosmos is due to deliver a preliminary plan by June 15, according to Rogozin.

"As for our manned flights plans beyond 2020 - we would probably have new projects with an expanded number of partners," he said, specifying that a general agreement has been reached with China and that negotiations of further Russia-China space cooperation are due to start in late June. India has also expressed interest in joint space exploration programs, he said.

The Chinese are making great progress in space exploration but it does not mean Moscow and Beijing are necessarily discussing development of a joint space station, Rogozin stressed.

Moscow to close US GPS Stations
Rogozin once again confirmed that Moscow is firmly set to shut down 11 American correctional GPS stations situated in Russia's 10 regions on June 1 if Washington continues to ignore Moscow's requests on deployment of similar stations on US territory.

If there is no reaction from the US by May 31, the GPS stations will suspend operation for the next three months.

If that does not help either, the operation of GPS stations in Russia will cease to exist by August 31, Rogozin promised, adding that this will not interfere with ordinary users of the system in Russia, because the information collected by these stations is being used primarily by the US military and national security agencies.

"These [GPS] stations are situated primarily alongside the Northern Sea Route and it is a big question why they were deployed on our territory in the mid-1990s and for what purpose," the Deputy PM said, stressing that once the stations are gone, "the American military would feel the difference, whereas Russian GPS users would not."

SpaceX CEO, founder and chief designer Elon Musk is set to unveil the manned version of his firms commercial Dragon spaceship later this week, setting in motion an effort that he hopes will soon restore America's capability to launch US astronauts to low Earth orbit and the International Space Station (ISS) by 2017.

Musk will personally introduce SpaceX's 'Space Taxi' dubbed 'Dragon V2' at what amounts to sort of a world premiere event on May 29 at the company's headquarters in Hawthorne, CA, according to an official announcement this evening (May 27) from SpaceX.

"SpaceX's new Dragon V2 spacecraft is a next generation spacecraft designed to carry astronauts into space," according to the SpaceX statement.

The manned Dragon will launch atop the powerful SpaceX Falcon 9 v1.1 rocket from a SpaceX pad on the Florida Space Coast.

Dragon was initially developed as a commercial unmanned resupply freighter to deliver 20,000 kg (44,000 pounds) of supplies and science experiments to the ISS under a $1.6 Billion Commercial Resupply Services (CRS) contract with NASA during a dozen Dragon cargo spacecraft flights through 2016.

Musk is making good on a recent comment he posted to twitter on April 29, with respect to the continuing fallout from the deadly crisis in Ukraine which has resulted in some US economic sanctions imposed against Russia, that now potentially threaten US access to the ISS in a boomerang action from the Russian government:

"Sounds like this might be a good time to unveil the new Dragon Mk 2 spaceship that @SpaceX has been working on with @NASA."

"No trampoline needed," Musk tweeted. The 'Dragon V2' is an upgraded, man rated version of the unmanned spaceship that can carry a mix of cargo and up to a seven crewmembers to the ISS.

Dragon is among a trio of US private sector manned spaceships being developed with seed money from NASA's Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the ISS by 2017, a capability totally lost following the space shuttle's forced retirement in 2011.

NASA astronauts and industry experts check out the crew accommodations in the Dragon spacecraft under development by SpaceX. 

The evaluation in Hawthorne, Calif., on Jan. 30, 2012, was part of SpaceX’s Commercial Crew Development Round 2 agreement with NASA’s Commercial Crew Program.

Since that day, US astronauts have been totally dependent on the Russian Soyuz capsules for ferry rides to orbit and back.

The Boeing CST-100 and Sierra Nevada Dream Chaser 'space taxis' are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.

All three company's have been making excellent progress in meeting their NASA mandated milestones in the current contract period known as Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA's Commercial Crew Program.

Volocopter VC200: Vertical take-off and landing manned aircraft

The flying machine looks something like a helicopter but it is quite different and is intended to be a future answer to the greening of noisy, vibration-heavy helicopters as we have known them.

A two-seater prototype of the Volocopter, by the company e-volo, made its maiden voyage earlier this month in Karlsruhe, Germany.

The team used a prototype of the two-person VC200.

Based on this model, it will be prepared for series production. Billed by its makers as "the world's first green helicopter," the emission-free Volocopter is a vertical take-off and landing manned aircraft, with features that set it apart from conventional aircraft.

For one, the machine, instead of being kitted out with one combustion engine, carries eighteen electrically driven rotors to propel it. Through the propellers, the Volocopter can take off and land vertically just as does a helicopter.

The team responsible for the machine said the 18 rotors present a considerable advantage, apart from the simple construction not requiring complex mechanics.

The advantage is said to be in the redundancy of drives. This enables the safe landing of the Volocopter even if some drives fail.

During the first flights of the prototype in November, the team made note that the device had a lower noise level than conventional helicopters, confirmation of no noticeable vibrations in flight, and an efficient spring strut landing gear.

Speaking about vibrations, e-volo's Stephan Wolf said that vibrations in the structure of a plane have been problems for normal helicopters, and that vibrations together with the high noise level have led to passenger discomfort but their "green" version resolves such issues.

Wolf and Alexander Zosel, CEO, stated that "not even the HD video cameras secured to the exterior carbon ring of the rotor plane captured the least vibrations."

The VC200 two-seater Volocopter plans involve the following characteristics: a cruising speed of at least 54 kn (100 km/h); a flight altitude of up to 6500 ft; maximum take-off weight of 450 kg; and more than one hour of flight time.

At present, a battery flight time of 20 minutes is possible, according to the company site, but in the near future this will be extended to one hour or more.

E volo was the winner of the 2012 Lindbergh Prize for Innovation. "We believe that the development of the Volocopter holds significant promise to radically change short distance transportation," said Erik Lindbergh.

"It has a long development path ahead, but if this innovative design reaches the commercial market it will dramatically change the way we move about the planet."



As for safety, the team notes that an integral part of the safety of the Volocopter is the redundancy of its components, such that the Volocopter is safe to fly even if several drive units fail.

Even if the range extender fails, a safe landing is ensured by additional batteries.

The Volocopters are fitted with a parachute that lets the entire aircraft sink to the ground in the case of an emergency.

Progress made during the next year or so will determine whether a private manned Mars mission can get off the ground in 2018 as planned, its organizers say.

The pressure is on the nonprofit Inspiration Mars Foundation, which intends to launch two astronauts on a flyby mission around the Red Planet in January 2018.

If the team misses this window, the next one won't open until 2031, when Earth and Mars are again suitably aligned for a fast roundtrip trek.

"We acknowledge the reach that this represents," Taber MacCallum, Inspiration Mars' chief technology officer, said of getting everything organized in less than five years.

"The next year of effort on this is really going to tell, I think, whether or not we are able to close this as a mission."
