'Impossible' rocket drive works and could get to Moon in four hours
The British designed EM Drive actually works and would dramatically speed up space travel, scientists have confirmed

Interplanetary travel could be a step closer after scientists confirmed that an electromagnetic propulsion drive, which is fast enough to get to

in four hours, actually works.

The EM Drive was developed by the British inventor Roger Shawyer nearly 15 years ago but was ridiculed at the time as being scientifically impossible.

It produces thrust by using solar power to generate multiple microwaves that move back and forth in an enclosed chamber. This means that until something fails or wears down, theoretically the engine could keep running forever without the need for rocket fuel.

The drive, which has been likened to

Impulse Drive, has left scientists scratching their heads because it defies one of the fundamental concepts of physics – the conservation of momentum – which states that if something is propelled forward, something must be pushed in the opposite direction. So the forces inside the chamber should cancel each other out.

However in recent years Nasa has confirmed that they believe it works and this week Martin Tajmar, a professor and chair for Space Systems at

in Germany also showed that it produces thrust.

The drive is capable of producing thrust several thousand times greater than even a photon rocket and could get to Mars within 70 days or Pluto within 18 months. A trip to Alpha Centauri, which would take tens of thousands of years to reach right now, could be reached in just 100 years.

"Our test campaign cannot confirm or refute the claims of the EM Drive but intends to independently assess possible side-effects in the measurements methods used so far," said Prof Tajmar.

"Nevertheless, we do observe thrust close to the actual predictions after eliminating many possible error sources that should warrant further investigation into the phenomena."

"Our measurements reveal thrusts as expected from previous claims after carefully studying thermal and electromagnetic interferences.

"If true, this could certainly revolutionise space travel."

Shawyer also claims that he is just a few months away from publishing new results confirming that his drive works in a peer reviewed journal.

However scientists still have no idea how it actually works. Nasa suggested that it could have something to do with the technology manipulating subatomic particles which constantly pop in and out of existence in empty space.

Prof Tajmer presented his findings to the 2015

Earth Will Only Have 12 Hours To Prepare For Massive Solar Storm

XKx6QHy.jpg

Trains will be disrupted, power will go out, satellite signals will go wonky - that’s what we have to look forward to when the sun next has a melt down, and we’re unlikely to get more than 12 hours warning.

In a new government document, the Department of Business, Innovation and Skills has laid out its Space Weather Preparedness Strategy, outlining the risks of unsettled space weather as well as what it plans to do about them.

The document explains that the worst case scenario is a ‘coronal mass ejection’ - huge eruptions on the sun which cause parts of its corona to detach. The corona is the pearly glow around the sun that you can only usually see during a total solar eclipse, made up of plasma and rarefied gases.

The worst case scenario is based on the Carrington event of 1859, which caused solar-flare related x-rays and radiation storms. In 2015, a similar event could cause the national grid to fail, satellite operations to shut down, increased radiation on flights and upset to electronic systems.

The report suggests that there are three things the country needs to do to prepare for such an event: improve alerts and warnings, update power and communication infrastructure with failsafe backups and have a plan in place to deal with the effects should they come to pass.

As for you: the advice from the government is to prepare yourself for a solar event just as you would for any other natural hazards like floods and storms.

NASA informed lawmakers on Wednesday that because Congress has failed to fully fund its Commercial Crew Program for the last five years, it is signing a $490 million contract extension with Russia to send Americans to space.

The new contract, running through 2019, means that NASA will continue to depend on Russia to get its astronauts to space even as tensions between Washington and Moscow escalate.



It will put money in Russia’s pockets even as U.S. economic sanctions seek to put pressure on Russian President Vladimir Putin’s government over the conflict in Ukraine.


It will also make the U.S. susceptible to threats from Russia, which in the past has suggested it could stop taking U.S. astronauts to the International Space Station. The U.S. has relied on Russia since retiring its space shuttle program.

In a letter to a key House appropriator on Wednesday, NASA Administrator Charles F. Bolden Jr. also warned that the space program is in danger of missing a 2017 deadline to send U.S. astronauts to space on vehicles created by Boeing and SpaceX.

To meet that deadline, he wrote that Congress needs to meet President Obama’s $1.24 billion budget request for the program.

“The fastest path to bringing these new systems online, launching from America, and ending our sole reliance on Russia is fully funding NASA's Commercial Crew Program in FY 2016,” Bolden wrote in a letter to Rep. John Culberson (R-Texas), who oversees NASA funding in the House.

For the next fiscal year, House Republicans have proposed allocating nearly $250 million less than the request, while Senate Republicans would offer $300 million less.

If Congress doesn’t increase the allocation, Boeing and SpaceX likely will receive orders to immediately suspend all operations either next spring or summer, Bolden said.

And if those orders are issued, Bolden said the existing contracts “may need to be renegotiated, likely resulting in further schedule slippage and increased cost.”

The new contract extension is required because Congress has not fully funded the administration’s budget requests since 2010.

For fiscal year 2011, for example, Obama asked Congress for $500 million for NASA’s Commercial Crew Program. Congress only gave it $321 million. The next year, Obama asked for $850 million and Congress only allocated $400 million.

Due to those low funding levels for five consecutive years, NASA had to ask Congress for more than $1 billion for next year.

A spokeswoman for NASA said if Obama’s request is fully funded, and if NASA can fully pay its contracts, the U.S. commercial vehicles could still be ready by the 2017 date.

“At this point, because of the lack of funding, our commercial partners will likely not be ready by 2017,” the spokeswoman said.

Republicans in both chambers have blamed tight spending ceilings enforce by a 2011 budget deal for the problems. Democrats and the White House want to raise those ceilings for a variety of programs. Some Republicans are against raising any of the ceilings, while others in the GOP want to just raise the ceilings for certain programs, such as defense spending.

Senate Majority Leader Mitch McConnell (R-Ky.) on Tuesday repeated his promise to reporters that he would not allow any more government shutdowns and that Republicans would negotiate with Democrats over spending levels “at some point."

Orion service module still seen as schedule driver

The pace of the European Space Agency’s development of a power and propulsion module for NASA’s Orion crew capsule will likely determine when an unpiloted test flight of the spaceship and its heavy-lift rocket will take off, NASA officials said last week.

The first flight of NASA’s Space Launch System is currently penciled in some time between July and September 2018, according to Bill Hill, NASA’s deputy associate administrator for exploration systems development.

“We’re a little more than three years away,” Hill told members of the NASA Advisory Council’s human exploration subcommittee July 28.

The mission will send an uncrewed Orion spacecraft into lunar orbit for a mission lasting more than 20 days. The capsule will return to Earth for a parachute-assisted ocean splashdown in a final shakedown before NASA adds final life support systems and crew accommodations for a manned flight around 2021.

NASA working on the deep space exploration rocket and capsule programs under a budget projected at approximately $3 billion per year.

Bill Gerstenmaier, head of NASA’s human spaceflight directorate, told members of the subcommittee the Orion capsule’s European-made service module, which is being developed by Airbus Defense and Space, will probably be the last piece of the critical test flight to be ready for launch.

NASA and ESA officials, together with contractors from Orion-builder Lockheed Martin and Airbus, have discussed shipping the Orion service module from Europe to NASA’s Kennedy Space Center in Florida before it is finished. European engineers could travel to the Florida spaceport to complete construction of the service module before its integration with the Orion crew capsule, which is to be assembled by Lockheed Martin at KSC’s Armstrong Operations and Checkout Building.

Engineers plan to introduce changes to the Orion crew module after a successful orbital test flight in December 2014. The upgrades include a switch from a monolithic heat shield made of ablative Avcoat material to blocks of Avcoat, a change intended to improve the manufacturability of the thermal protection system.

Last year’s Orion demonstration, called Exploration Flight Test-1, launched on top of a United Launch Alliance Delta 4-Heavy booster, which sent the capsule to an altitude of approximately 3,600 miles on a four-and-a-half hour mission.

The Orion service module, which did not fly on EFT-1, will include propellant tanks, batteries, pressure vessels, four solar array wings and a hypergolic engine for major burns during the mission. NASA is supplying ESA with a space shuttle Orbital Maneuvering System engine to power the Orion spacecraft, with delivery of the engine to Europe expected in early 2016, according to a schedule chart presented by Hill.

ESA is in charge of the service module’s structure, electrical system and fuel tanks. It is the first time NASA has entrusted an international partner with a major component in the critical path of a human spaceflight program.

Without ESA’s part, NASA officials said the first SLS/Orion flight — known as Exploration Mission-1 — could be delayed even further due to U.S. budget constraints. Before partnering with ESA, NASA did not have funding to complete development of the service module in time for a flight in 2017, the original target launch date for EM-1.

The ESA-funded development of the Orion service module counts as Europe’s contribution to the International Space Station’s annual operating costs from 2017 through 2020. ESA discontinued flights of its cargo delivery craft, the Automated Transfer Vehicle, in 2014.

The Orion service module builds on technologies flown on the ATV’s space station resupply missions.

ESA is responsible for paying NASA for 8.3 percent of the space station’s operating budget each year, but the agencies prefer to process the payment through a barter agreement instead of cash. For the years 2017 through 2020, ESA says the service module agreement represents a payment to NASA of 450 million euros, or about $500 million.

Gerstenmaier said the schedule for the Orion service module was always cramped. NASA did not cinch the agreement with ESA to produce the power and propulsion element until early 2013, after European member states formally agreed to the program.

Other components for the EM-1 test flight have been in design for years longer. In the case of the Orion crew module, where astronauts will live on manned missions set to begin in 2021, development kicked off with NASA’s signing of a contract with Lockheed Martin in 2006 for the agency’s now-canceled Constellation moon program.

Construction of the Space Launch System’s core stage, a huge reservoir of liquid hydrogen and liquid oxygen for the rocket’s four RS-25 main engines, is also a schedule driver for the 2018 test flight.

The Boeing-built core stage is 27.5 feet in diameter and stands more than 200 feet tall. Special tools were installed at NASA’s Michoud Assembly Facility in New Orleans to assemble the rocket’s tanks and cylindrical primary structure.

The schedule is too tight to build a full-up test article, so the core stage intended to fly on EM-1 will be shipped to nearby Stennis Space Center in Mississippi in mid-2017 for an all-up test firing with its four RS-25 engines. If the ground verification goes well, the rocket will head to the launch base at the Kennedy Space Center in early 2018.

“I think getting the core stage integrated and tested at Stennis is one of the primary challenges,” Hill told the NASA advisory subcommittee. “I think the Orion (crew module) will make it, only because we’ve been through EFT-1. The European service module will probably be the pacing item to get through launch.”

The Orion program’s confirmation review, a key milestone in any NASA project, is nearing completion, according to Greg Williams, a deputy associate administrator for policy and plans.

The outcome of the confirmation review will bring clarity to the Orion program’s total cost and schedule.

Williams told the NASA Advisory Council that the agency’s leadership has declared the Orion program technically ready to continue into the next phase of development. Formal schedule and cost commitments are still being worked out.

Technicians at Michoud plan to begin welding pieces of the pressure shell for the next Orion crew module in September, according to Hill. The final welds should be complete by December, and Lockheed Martin will transport the craft to KSC in January for pressure testing and outfitting with computers, fuel tanks, thrusters, a heat shield and other systems.

Thales Alenia Space, a subcontractor to Airbus on the Orion service module, is testing a structural pathfinder of the element in Italy. The test article will go to NASA’s Plum Brook Station in Ohio for shake tests in October, Hill said.

Once the Orion crew and service modules are finished, NASA will send the units to Plum Brook in 2017 for combined testing in a huge thermal vacuum chamber to mimic the conditions of space. They will return to KSC for final flight preps.

ULA is kicking off production of the SLS upper stage’s first flight unit, which is propelled by an Aerojet Rocketdyne RL10 engine. The rocket is an interim upper stage for the heavy-lift launcher, and it is based on the Delta 4 booster’s five-meter (16.4-foot) second stage.

Preparations on the Space Launch System’s twin solid rocket boosters is also due to start soon at Orbital ATK’s facilities in Utah. A final qualification firing of a stationary booster is scheduled for April 2016.

Work on SLS ground systems at KSC is also proceeding, Hill said.

Structural modifications to the SLS mobile launch platform, originally built for the ill-fated Ares 1 rocket, were finished in July under a $20 million contract with a local Florida construction firm, Hill said.

A new contract should be signed within weeks to add cladding and support arms to the mobile launch tower, which is sitting outside the Vehicle Assembly Building at KSC. The addition of new work platforms inside the cavernous VAB’s High Bay 3 is about 30 percent complete, according to Hill.

Eleven construction projects are underway at launch pad 39B, where SLS missions will take off. The work includes refurbishment of the flame trench and sound suppression water system.

Ground systems at KSC should be ready around the end of 2017, officials said.

Nasa is the main contractor they subcontracted the work and gave the ESA the work on the service module, but the whole thing is basically being redesigned because the supposed testing model they launched was anything but.

farther more it's a rocket without a mission. It looks great on paper but NASA has no defined goals for it. it's all wishy washy, And Now Some are pushing to make a it like the European Ariane program where the whole thing is run on subsidies from the Participating governments.

Astronomers discover humongous structure one-ninth the size of the observable universe

.

“If we are right, this structure contradicts the current models of the universe,” said Lajos Balazs, lead author on the paper, in a
Please, Log in or Register to view URLs content!
. “It was a huge surprise to find something this big – and we still don’t quite understand how it came to exist at all.”

Just what is this massive structure? It's not a single, physical object, but rather a cluster of nine massive galaxies bound together gravitationally, much like how our Milky Way is part of a cluster of galaxies. It was discovered after researchers identified a ring of nine gamma ray bursts (GRBs) that appeared to be at very similar distances from us, each around 7 billion light years away.

GRBs are the brightest electromagnetic events known to occur in the universe, caused by a supernova. Their detection typically indicates the presence of a galaxy, so all of the GRBs in this ring are believed to each come from a different galaxy. But their close proximity to one another suggests that these galaxies must be linked together. There is only a 1 in 20,000 probability of the GRBs being in this distribution by chance.

A mega-cluster of this size shouldn't be possible, at least not if you think in terms of our current theories. Those theories predict that the universe ought to be relatively uniform on the largest scales, meaning that the sizes of structures shouldn't vary by much. In fact, the theoretical limit to structure size has been calculated at around 1.2 billion light years across.

If the Hungarian-American team's calculations are correct, then this giant new structure-- which measures in at over 5 billion light years across — would blow that classic model out of the water. In fact, either the researchers' calculations are wrong on this, or scientists will need to radically revise their theories on the evolution of the cosmos.

Needless to say, this GRB cluster discovery has the potential to cause a sweeping paradigm shift in astronomy. At the very least, it reminds us just how small our view of the universe really is.

The Brazilian Space Agency is preparing its biggest launch of the year

ITveCq7.jpg

(Defensa.com) The Alcantara Launch Center (CLA), in Maranhão, received this week with experts and researchers to the Meeting of Accompaniment Interfaces (RAI) of the call Operation São Lourenço. The aim is to coordinate the actions for the implementation and monitoring of a new rocket VS-40M probe in October and November, leading to a space platform called Satellite Atmospheric Reentry (Sara), both developed by the Institute of Aeronautics and Space (IAE), the organization of the Command of the Air Force subordinate to the Department of Aerospace Science and Technology (TABD).

In addition to members of the TABD, IAE and CLA also participate in these meetings defining civil and military Launch Center Barreira do Inferno (CLBI) in Natal officials, and the Institute for Coordination and Industrial Development (IFI). In parallel, the CLA also has the fundraising of Operation São Lourenço. Activities include the installation of mechanical devices in the Middle Porte Launcher (LPM) recently revitalized and integration testing of a model, prototype rocket VS-40M-scale, through the stages of assembly, transport and LPM integration, testing devices and the launcher itself as well as the reverse processes of removing the launchpad, transport and removal.

Scheduled to take place between October 13 and November 7, operation, as well as pointing to the launch vehicle and monitoring VS-40M with Sara space platform, also is carrying a GPS application in the qualification phase space and developed by the Federal University of Rio Grande do Norte (UFRN). To ensure the operation of all the personnel involved and the means of CLA a rocket Intermediate Training (FTI) should be launched into space before the VS-40M

IAE researchers intend to continue the Sara project, which includes the development of a space station for microgravity experiments designed to operate at low circular orbit at 300 km altitude for a period up to 10 days.

Through a successful launch, some subsystems of the "Sara" Suborbital system as power grids, recovery systems, structure, module experiments, cold gas and thermal protection must go through the qualification flight. Moreover, with the qualification of Electrical Safety Nets and built to service the VS-40M, the same may be used in the future Satellite Launch Vehicle (VLS-1). During the crawl space launch vehicle and interconnecting telemetry stations, radar and data processing location of CLA (Alcantara) with stations CLBI (Natal), in order to implement the communication system must occur between remote stations, essential to maintain the operation of the two launch centers.

Subsystem "Electrical networks of SARA", developed and manufactured by Mectron, it has an architecture in which the electronics shipped in the payload is shared with its launch vehicle, with the logic of cost and weight reduction. It has a service network for the supply of energy and the sequence of events on the flight, a network of telemetry with the function of collecting and transmitting flight data to the ground station, a control network, composed of the inertial sensor on-board computer, power electronics and cooling actuator gas, in order to get closer to zero the angular velocity of the platform and Network Security, responsible for receiving and decoding the remote land and activating the vehicle's flight termination VS-40, if an abnormal path develops.

The VS-40 has been put into orbit twice in Brazil, both from the CLA, (Operation Santa Maria - 1993 Operation Livramento, in 1998) and most recently in Norway to support the program microgravity Space Agency European (ESA) in June 2012.La Operation São Lourenço is the main activity of launching and tracking for this year's Brazilian space program, in coordination with the Brazilian Space Agency (AEB). Between next year and 2017 year, the SARA platform, on his first mission will be launched by a VS-40 modified vehicle survey, produced by the IAE, from the Launch Center of Barreira do Inferno - CLBI, Natal, Rio Grande do Norte, in suborbital flight, in order to qualify the device and its remaining subsystems.

Scientists discovered the last lake on Mars, which might be preserving ancient life

0hiqgLn.jpg

Illustration of what Mars would look like with water.

A trio of scientists says they've identified the best place to look for evidence of ancient life on Mars — one of the youngest lake-bearing basins ever discovered.

Though Mars has no liquid water today, the Red Planet was submerged under vast oceans billions of years ago. And where there's water, there's the potential for life.

Scientists suspected that after the oceans evaporated, that was it for water — and life — on Mars. But a recent paper published in the journal
Please, Log in or Register to view URLs content!
says that's not the case.

Mars had a second wave of surface water about 3.6 billion years ago — 200 million years after scientists thought Mars had seen the last of its liquid water. This water, the researchers report, was located in a lake inside a basin near the Martian equator, about 100 miles from where NASA's Opportunity rover rests today.

It is one of the youngest lakes and therefore possibly one of the last liquid water sources to ever exist on Mars, the researchers report.

The discovery is exciting for the prospect of ancient Martian life, explains lead author Brian Hynek who is a research associate at the Laboratory for Atmospheric and Space Physics at Colorado University-Boulder:

"Having a later stage of water on Mars is probably a good thing for the potential for life on that planet because it gave life more time to be conceived," Hynek told Business Insider. "There was life on Earth when this lake was active so by that analogy, we can say there's potential that Mars had microbial life and this was a great place where it could have resided."

Getting around a tricky problem

Crater in Meridiani Planum, where the researchers found evidence for one of the youngest lakes ever discovered.

The researchers are investigating the age and origin of hundreds of salt deposits across Mars to map how much water existed on the surface.

"Just like on Earth, when salts are left somewhere, that probably means that water was there," Hynek said. "So, these are indicators that water was there in some form."

Estimating the age of these salt deposits is tricky. The way scientists determine the age of anything on Mars is by counting the number and measuring the size of impact craters in that region. Then they compare this information to similar regions on the Moon, whose age we have a better handle on.

But wind has eroded the regions where these salt deposits are located, which makes it hard to estimate their age. This latest paper is the first time anyone has ever calculated with any confidence the age of one of these salt deposits, Hynek said.

Using images taken by NASA's Mars Reconnaissance Orbiter, which has been orbiting Mars since 2006, the team studied the terrain and geography around the basin. They found evidence to suggest that at one point, the lake grew large enough to spill over the rim of the basin, carving channels in its wake.

The researchers traced these channels to neighboring volcanic plains hundreds of miles away that are about 3.6 billion years old. Because the water channels over-cut the volcanic plains, they must be younger. That means the lake must also be younger than 3.6 billion years.

Life locked in salt
57wsPtY.jpg

(Promking at en.wikipedia)
Bonneville Salt Flats in Utah are similar to the salt deposits on Mars.

Right now, there are no plans to visit this basin in search for the potential for life. But Hynek hopes that this latest paper will make the basin a more popular touch down point for the NASA Mars rover scheduled to launch in 2020.

Hynek has a pretty good idea of where he'd look first:

"I think you'd want to target the salt deposits," he told Business Insider. "As the water evaporates away a lot of organic matter and a lot of microbial evidence gets encased in salts and is preserved for long time periods."

Though there was liquid water in the basin, there are still other factors that would ultimately determine whether life could have existed there, Hynek cautions. The lake's salinity, acidity, oxygen levels, and available nutrients for food are all important.

The lake had a relatively low salt content, which would have made it ideal for life, Hynek said. However, the other three factors are hard to measure without sending a rover there to scoop up the soil and analyze what's in it.

So far, this single lake is the only evidence for water on Mars around 3.6 billion years ago. Hynek plans to continue studying these salt deposits to see if there's more evidence of water on a younger Mars.
