“Google Street View” of the Cosmos Unveiled

A new home-grown instrument based on bundles of optical fibres is giving Australian astronomers the first ‘Google street view’ of the cosmos — incredibly detailed views of huge numbers of galaxies. Developed by researchers at the University of Sydney and the Australian Astronomical Observatory, the optical-fibre bundles can sample the light from up to 60 parts of a galaxy, for a dozen galaxies at a time. The technological leap is the ‘hexabundle’, sixty or more optical fibres close-packed and fused together, developed by the University of Sydney’s astrophotonics group.

Using the new instrument astronomers from the Australian National University and the University of Sydney have already spotted ‘galactic winds’—streams of charged particles travelling at up to 3,000 km a second—from the center of two galaxies.“We’ve seen galactic winds in other galaxies, but we have no idea how common they really are, because we’ve never had the means to look for them systematically. Now we do,” said the University of Sydney’s Associate Professor Scott Croom, a Chief Investigator on the project.

‘Impossible’ Space Engine Might Work, NASA Test Suggests

NASA researchers have reported fresh evidence that an “impossible” space propulsion technology might actually work.

A study from NASA’s Johnson Space Center in Houston says a microwave thruster system that requires no propellant appears to generate a tiny amount of thrust. If the technology pans out, it could make spaceflight far cheaper and speedier, advocates say. They argue that the thruster harnesses subatomic particles that pop into and out of existence in accordance with quantum physics — a hypothesis that’s mentioned in the study.

Something is Amiss with Light in the Universe –“Photons May Be Coming from Some Exotic Unknown Source”

Posted by in category: space

The Daily Galaxy
Dark-energy

The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise “light meter.” In a recent study published in The Astrophysical Journal Letters, a team of scientists finds that the light from known populations of galaxies and quasars is not nearly enough to explain observations of intergalactic hydrogen. The difference is a stunning 400 percent.
“The most exciting possibility is that the missing photons are coming from some exotic new source, not galaxies or quasars at all,” said Neal Katz a co-author from the University of Massachusetts at Amherst. For example, the mysterious dark matter, which holds galaxies together but has never been seen directly, could itself decay and ultimately be responsible for this extra light.

Why Billionaire Elon Musk Is Worried About Artificial Intelligence

Posted by in categories: space, space travel

— The Blaze
Billionaire Musk Likes Solar Energy and Putting Humans on Mars, But Says We Must Be Careful With Artificial Intelligence
Billionaire Elon Musk has a passion for advancing technology; he recently announced plans to create the world’s single largest solar production and told CNBC he wants to put humans on Mars by the end of the 2020s.

But it appears there’s one area of technology he isn’t ready to push: artificial intelligence.

100 Year Starship Call for Papers // 2014 Public Symposium

Posted by in categories: asteroid/comet impacts, astronomy, futurism, science, space, space travel

logo for the symposium transparent b100 Year Starship announces a Call for Papers for the 100YSS 2014 Public Symposium. The Symposium will be held September 18–21 at the George R. Brown Convention Center in Houston, Texas, United States.

You’re invited to submit your abstract for one of the eight Technical Tracks or Poster Session and be a part of our transdisciplinary scope to include the broadest swath of ideas and people for our mission. Abstract deadline is 20 June, 2014.

The Pathway to the Stars, Footprints on Earth theme still guides the focus of 100YSS’s Public Symposium. It compels us to continue our journey and maintain our mission. Last year, our participants explored different avenues of fundamental research, technology development, societal systems, and capacities that facilitate ready access to our inner solar system. This year we move that focus forward with more in-depth access to emerging and cutting edge topics – expanding our view of design, creating new pathways in education, discovering psychology, and cutting edge transportation methods. Using a collaborative and Transdisciplinary approach to capability and capacity building, our mission will continue to support our efforts to enhance life here on earth…today. Join us as we log another year in our 100-year mission at the 100YSS 2014 Public Symposium.

Below are the tracks for our 2014 Call For Papers.

The Navy’s Rail Gun technology hides a secret, that the Navy’s projectile accuracy has been substantially increased by about 45x.
But first some history.

Are you ready for contact with extraterrestrial intelligence?

Posted by in categories: first contact, human trajectories, space, space travel

Kurzweil Accelerating Intelligence

Some SETI (search for extraterrestrial intelligence) scientists are considering “Active SETI” to detect possible extraterrestrial civilizations.

Psychologist Gabriel G. de la Torre, professor at the University of Cádiz (Spain) questions this idea, based on results* from a survey taken by students, which revealed a general level of ignorance about the cosmos and the influence of religion on these matters.

NASA Spacesuit Design With Sci-Fi Flair Prepares For Mars Missions

Posted by in categories: engineering, space, space travel

Written By: Jason Dorrier — Singularity Hub

Electroluminescent wiring and patches form the suit’s flashiest components—recalling the visual effects of suits worn in Tron, if not the fit. NASA says such lighted features might serve to more easily identify crew members.

NASA may have decommissioned the Space Shuttle, but it’s not the end of space exploration for the iconic agency which wants to send humans back to the Moon and on to Mars within the next few decades. And they’ll need something to wear up there—something tailored for the next generation of space travel.

The agency first introduced its Z-series prototype spacesuits back in 2012.

The Realistic Cost Of The Next Space Race

Posted by in categories: business, economics, engineering, finance, hardware, innovation, policy, space, space travel

Based on the Bloomberg TV program “The Next Space Race” and other reliable sources, I determine the realistic payload costs goals for the next generation of private space companies.

I review NASA’s Space Shuttle Program costs and compare these with SpaceX costs, and then extrapolate to Planetary Resources, Inc.‘s cost structure.

Three important conclusions are derived. And for those viewing this video at my blog postings, the link to the Excel Spreadsheet is here (.xlsx file).

The Next Space Race

Posted by in categories: engineering, finance, innovation, physics, science, space, space travel

Yesterday’s program, The Next Space Race, on Bloomberg TV was an excellent introduction to the commercial aerospace companies, SpaceX, the Sierra Nevada Company (SNC), and Boeing. The following are important points, at the stated times, in the program:

0.33 mins: The cost of space travel has clipped our wings.
5:18 mins: How many people knew Google before they started?
7:40 mins: SpaceX costs, full compliment, 4x per year at $20 million per astronaut.
11:59 mins: Noisy rocket launch, notice also the length of the hot exhaust is several times the length of the rocket.
12:31 mins: One small step for man, one giant leap for mankind.
12:37 mins: Noisy shuttle launch, notice also the length of the hot exhaust is several times the length of the rocket.
13:47 mins: OPF-3, at one time the largest building in the world at 129 million cubic feet.
16:04 mins: States are luring private companies to start up in their states.
16:32 mins: NASA should be spending its money on exploration and missions and not maintenance and operations.
17:12 mins: The fair market value of OPF-3 is about $13.5 million.
17:19 mins: Maintenance cost is $100,000 per month
17:47 mins: Why Florida?
18:55 mins: International Space Station (ISS) cost $60B and if including the Shuttle program, it cost $150B.
19:17 mins: The size of the commercial space launch business.
21:04 mins: Elon Musk has put $100 million of his own money into SpaceX.
21:23 mins: The goals of NASA and private space do not conflict.

Summary:
1. Cost of ISS is $60B, total cost including the Shuttle program is $150B.

2. SpaceX cost is $20M per astronaut (for 7 astronauts) or a launch cost of $140 million per launch at $560 million per year for 4 launches per year.
