Lockheed Martin has taken the wraps off its vision for a future manned lunar lander at International Astronautical Congress (IAC) in Bremen, Germany. The concept spacecraft is designed to show how a reusable lander, in conjunction with NASA’s planned lunar Gateway deep-space orbital outpost, can support an indefinite human presence on the Moon as well as providing valuable experience for the first manned missions to Mars.
It’s been almost half a century since the last astronauts set foot on the Moon and with new US plans committing NASA to a program of sustained human exploration and exploitation of deep space, returning to the lunar surface will involve much more than simply taking up where Apollo left off. Not only has technology advanced considerably since the 1960s, but making more than temporary and sporadic visits to the Moon and beyond requires a whole new approach to space exploration. read more
Since they’re basically invisible, it can be hard to pin down just how big a black hole is. They can range anywhere from a few times the mass of the Sun up to millions or billions times that mass, but there’s a potential class that are even bigger than that. read more
For a long time, Earth was the weirdest planet we knew about. In our little corner of the universe, where Mercury is the hot one, Jupiter is the protective bigger brother, and Pluto is the one we kicked out of the club for breaking the rules, Earth is the crazy cat lady, hoarding billions of life forms. read more
According to the Lambda Cold Dark Matter (Lambda-CDM) model, which is the current accepted standard for how the universe began and evolved, the ordinary matter we encounter every day only makes up around five percent of the universe’s density, with dark matter comprising 27 percent, and the remaining 68 percent made up of dark energy, a so-far theoretical force driving the expansion of the universe. But a new study has questioned whether dark energy exists at all, citing computer simulations that found that by accounting for the changing structure of the cosmos, the gap in the theory, which dark energy was proposed to fill, vanishes. read more
It is set to become the largest rocket ever built, dwarfing the rockets that took man to the moon and paving the way for manned missions to Mars.
NASA today reveal stunning new pictures of its SLS (Space Launch System), which will eventually be capable of lifting 130 tons into orbit.
The rocket will be used to ferry astronauts to the International Space Station, and to help us explore the outer reaches of the solar system.
It is even hoped the craft could play a role in manned missions to Mars, being able to launch ‘stepping stone’ bases into orbit.
‘The potential use of SLS for science will further enhance the synergy between scientific exploration and human exploration,’ said John Grunsfeld, astronaut and associate administrator for science at NASA Headquarters in Washington. read more
A black hole has been found to be pumping out of iron and nickel into the universe – spewing out more powerful jets that scientists first thought.
Black holes usually put out jets of low-mass particles, thousands of light-years long, into surrounding galaxies.
These jets recycle matter and energy into space and can affect when and where a galaxy forms stars.

Would be astronauts looking to book the trip of a lifetime are being offered the chance to float into space in a high tech balloon.
A Spanish company plans on offering the ultimate day trip to near-space in two years time – just enough time to start saving for the £95,000 ($142,000) ticket.
During the flight, passengers will be able to stand up and enjoy fantastic panoramic views of Earth, experience weightlessness and even eat a meal if they desire.

During the flight passengers will be able to stand up in their pod (pictured) and enjoy fantastic panoramic views of Earth, while also being served a meal
The ëblooní is the brainchild of Spanish entrepreneur Jose Mariano Lopez-Urdiales, boss of Barcelona-based Zero2Infinity.
Space tourists will journey to earth’s outer limits in a capsule that can hold six people – four passenger and two pilots.
Annelie Schoenmaker of Zero2Infinity, said: ‘The ride will be very gentle and peaceful as well as environmentally friendly.
‘Passengers will be able to see the sun and the stars at the same time, while looking down on the curvature of the earth.’
The passenger pod is carried into near-space by a high tech balloon and then separates after cruising above the earth for two hours. It is carried back to Earth by a para-foil when passengers will briefly experience zero gravity
Russian adventurer Artemy Lebedev who is one of the few people on the planet to have visited every country, has already signed up for a trip to near-space.
Commercial operations will begin in 2015 but a trip for four people will cost around £95,000.
Ms Schoenmaker said: ‘The experience will be very much like that in an aeroplane although there will be a period of about 30 seconds when passengers will experience weightlessness and will be able to float around the cabin.
‘Everything is customised to the person’s individual requirements. We can partition off part of the cabin for those who want more privacy and we can even serve them Michelin star meals if that’s what they want.’
The pod is large enough to carry six passengers – four space tourists and two pilots. The company’s ‘Bloons’ are usually used to conduct science experiments in near space
Zero2Infinitydevelops technologies to enable cost-efficient access to near-space with zero-environmental impact flying solutions.
While it currently offers trips for scientific researchers as well as equipment in its ‘Bloon’ pods, it is targeting couples and families with this new venture.
Zero2Infinity’s largest pod, which carries six people, has 15 square metres of windows for amazing views of the Earth and space.
The company is currently doing test flights and raising more investment for its new venture.
JOURNEY OF THE BLOON TO THE EDGE OF SPACE
The balloons lift off from an aerodrome in Cordoba, Spain – although the location has not been confirmed
Ascent from the Earth’s surface to an altitude of 36 kilometers takes just one hour
The balloon and pod fly for around two hours at a height that is twice that of Concorde’s cruising altitude
The balloon vents gas to descend like a normal hot air balloon
The pod separates from the balloon, attached to a para-foil, which allows the passengers to experience zero gravity for around two minutes
Guided descent to a landing area takes around 40 minute
A Bloon begins its ascent from the Earth’s surface (above) to an altitude of 36 kilometers. They then fly for around two hours at a height that is twice that of Concorde’s cruising altitude

The company usually takes researchers and scientific experiments into near-space.
Its balloons offer scientists the chance to so earth and space observations, study atmospheric science, demonstrate technology in zero gravity conditions and conduct drop testing.
Zero2Gravity recently collaborated with Spanish university, Universitat Jaume, to send its humanoid robot called NAO into space.
The collaboration aims to advance in the development of robotics by offering a real platform to test university’s research in robotic intelligence.

When you look out into the Universe, what is it that you typically think of? Do you think of reliable, fixed stars and constellations? The vast expanse of the Milky Way, with its memorable dust lanes and amorphous shapes?
Image credit: Wally Pacholka of http://www.astropics.com/.The unchanging nature of the points of light in the sky?
Image credit: Roth Ritter (Dark Atmospheres), of the double cluster in Perseus.Maybe you think deeper and farther than that. Maybe you think about the distant galaxies and clusters, and the deepest deep-sky objects we know of. How the light took millions or even billions of years to reach us, and yet how every time we look at them, we see them exactly the same way.
Image credit: Misti Mountain Observatory.I couldn’t fault you for thinking like this; from mankind’s point of view, the Universe — for all intents and purposes — doesn’t change at all as we view it from one night to the next.But does that really mean the Universe isn’t changing?Let me flip this around on you: how much does anything here on Earth — you, your surroundings, even an entire, vibrant city — change in half-a-millisecond?
Image credit: DC User Forum, of a short-exposure shot with a Sony A900 DSLR.Not a whole lot, that’s for certain. You only change with the passage of time, and half-a-millisecond is just 0.00000000002% of a typical human lifetime. It’s too short of a timespan to notice any but the most catastrophic changes, and even then you have to look very closely.So why should you expect the Universe to change substantially over just 0.00000000002% of its lifetime? That’s how much of the Universe’s lifetime passes between one night on Earth and the next. And yet, if you looked at the right objects, you would be able to see meaningful changes from one night to the next.
Image credit: Tunc Tezel.The objects within our Solar System, for example, are close enough that we can see them moving from night-to-night. Objects closer to us — like Mars, in the foreground — appear to move more substantially than more distant objects like Uranus, visible in the background.The great cause of all this motion, of course, is our largest nearby clump of matter: the Sun. Objects like planets move at tens of kilometers-per-second relative to the Sun thanks to its gravity, while Sun-grazing comets can be accelerated up to speeds in the hundreds of kilometers-per-second. If you’re in the southern hemisphere, you may be able to get a good view of one now: Comet Lemmon.
Image credit: Rolf Wahl Olsen from Auckland, New Zealand.Green because of the carbon and nitrogen interacting with sunlight, this photo does an excellent job of tracking the stars from the Earth along with the Earth’s rotation. What you probably can’t tell is that the comet — with a photo exposure time of over an hour — is blurred.If instead of tracking the stars perfectly, we tracked the comet perfectly, know what we’d see?
Image credit: Peter Ward (Barden Ridge Observatory)That comet is moving relative to the stars behind it, and our ultra-close proximity to the comet makes it abundantly clear.But what you may not realize is that these “fixed” stars are also moving at tens-to-hundreds of kilometers-per-second relative to us, and relative to one another! It’s only the vast distances between us — measured in many light-years — that make it impossible to detect these changes from night-to-night.But we can’t really detect changes in ourselves from millisecond-to-millisecond; you simply need to look on longer timescales!
Image credit: Martha Haynes of Cornell University.The stars in our night sky shift positions by many kilometers each second. From night-to-night we might not be able to tell the difference, but just as you or I look different when we go weeks without cutting our hair, we can see just how the Universe changes over long enough timescales.
There are gas clouds and stellar remnants tearing through the interstellar medium at these same speeds, including some that move at thousands of kilometers-per-second, even approaching 1% the speed of light!
Image credit: NASA/ESA/Hubble Heritage Team and CTIO.There are new stars being born — where nuclear fusion ignites for the first time — and stars that run out of fuel, dying in either a planetary nebula or a supernova explosion, depending on the properties of the star.
Image credit: http://astrojan.ini.hu/, retrieved from Margaret Hanson, U. of Cincinnati.And on the largest scales, galaxies merge together, triggering star formation and some fabulous cosmic mashups, in processes taking upwards of hundreds-of-millions of years.
Image credit: Hubble Space Telescope, NASA, STScI and ESA.And in some of the fastest and most spectacular changes, catastrophic stellar events — like supernovae — can literally appear from nothing over the timescale of just a few nights!
Image credit: Peter Nugent/Palomar Transient Factory.When you look up at the Universe, it may appear static and unchanging, but that’s only because these objects are so far away and our human experiences are so short in comparison with the age of the Universe.But stick around for a while, and even the most mundane of objects will change for you. Fuel burns, elements fuse, gravity pulls, and physics happens. Just give it time, and you’ll see it for yourself.We may only be around for a snapshot of it, but make no mistake, it’s never the same from moment-to-moment. From the way I look at it, there isn’t any doubt about it: the Universe is alive.
The orbital balloon: NASA tests blow-up space-craft
A prototype inflatable module is to be tested aboard the International Space Station to give astronauts an extra bedroom, NASA has announced.
The inflatable module can be compressed into a 7ft tube for delivery, and is being heralded as a key component of future exploration and the development of commercial space travel and research.
It is designed by Bigelow Aerospace, based in Las Vegas, which has been awarded a $17.8 million (£11m) test project for the inflatable room – and hopes to develop space hotels and even planetary bases using the technology.

Astronauts will test the ability of the bladder, known as the Bigelow Expandable Activity Module, or BEAM, to withstand heat, radiation, debris and other assaults.
Some adventurous scientists might also try sleeping in the spare room, which is the first piece of private property to be blasted into space, NASA said.
Lori Garver, NASA’s deputy administrator, said as she unveiled the contract award that the inflatable module concept is simultaneously cutting edge technology and affordable.
‘This partnership agreement for the use of expandable habitats represents a step forward in cutting-edge technology that can allow humans to thrive in space safely and affordably, and heralds important progress in U.S. commercial space innovation,’ she said.
‘The International Space Station is a unique laboratory that enables important discoveries that benefit humanity and vastly increase understanding of how humans can live and work in space for long periods.’
Part of NASA’s interest in the inflatable technology is prompted by its potential for deep space missions.
If the module proves durable during two years at the space station, it could open the door to habitats on the moon and missions to Mars, Nasa engineer Glen Miller said.
The agency chose Bigelow for the contract because it was the only company working on inflatable technology, said NASA deputy administrator Lori Garver.

Founder and president Robert Bigelow, who made his fortune in the hotel industry before getting into the space business in 1999, framed the gambit as an out-of-this-world property venture.
He hopes to sell his spare-tire habitats to scientific companies and wealthy adventurers looking for space hotels.
NASA is expected to install the 13ft blimp-like module in a space station port by 2015.
Mr Bigelow plans to begin selling stand-alone space homes the next year.
The new technology provides three times as much room as the existing aluminium models, and is also easier and less costly to build, Mr Miller said.
Artist renderings of the module resemble a tin-foil clown nose grafted on to the main station. It is hardly big enough to be called a room.
Mr Miller described it as a large closet with padded white walls and gear and gizmos strung from two central beams.
