Figures.
New calculation shows that universal expansion appears to be 8 percent greater than expected, which isn’t good news.

Caltech’s 2500 Orbiting Solar Panels Could Provide Earth With Limitless Energy
Posted by Shailesh Prasad in categories: solar power, space, sustainability
The Space Solar Power Initiative (SSPI), a collaboration between Caltech and Northrup Grumman, has developed a system of lightweight solar power tiles which can convert solar energy to radio waves and can be placed in orbit to beam power to an energy-thirsty Earth.
One of the greatest challenges facing the 21st Century is the issue of power—how to generate enough of it, how to manufacture it cheaply and with the least amount of harmful side-effects, and how to get it to users.
The solutions will have to be very creative—rather like what the Space Solar Power Initiative (SSPI), a partnership between Caltech and Northrup Grumman, has devised.

SLAC researchers recreate the extreme universe in the lab
Posted by Andreas Matt in categories: nuclear energy, physics, space, supercomputing
Conditions in the vast universe can be quite extreme: Violent collisions scar the surfaces of planets. Nuclear reactions in bright stars generate tremendous amounts of energy. Gigantic explosions catapult matter far out into space. But how exactly do processes like these unfold? What do they tell us about the universe? And could their power be harnessed for the benefit of humankind?
To find out, researchers from the Department of Energy’s SLAC National Accelerator Laboratory perform sophisticated experiments and computer simulations that recreate violent cosmic conditions on a small scale in the lab.
“The field of laboratory astrophysics is growing very rapidly, fueled by a number of technological breakthroughs,” says Siegfried Glenzer, head of SLAC’s High Energy Density Science Division. “We now have high-power lasers to create extreme states of matter, cutting-edge X-ray sources to analyze these states at the atomic level, and high-performance supercomputers to run complex simulations that guide and help explain our experiments. With its outstanding capabilities in these areas, SLAC is a particularly fertile ground for this type of research.”

Is the Universe a Simulation? Scientists Debate

Hmm… That would explain Alzheimer disease — It’d be like some sort of unabashedly evil version of a smart phone data caps!
Or not.

Bigelow Aerospace and United Launch Alliance Join Forces to Foster a New Era of Sustainable Commercialization in Low Earth Orbit
Posted by Klaus Baldauf in categories: space, sustainability
Colorado Springs, Colo., (April 11, 2016) – Bigelow Aerospace (BA) and United Launch Alliance (ULA) announced they are partnering to develop and deploy habitable volumes in Low Earth orbit (LEO). The volumes will be based on the Bigelow Aerospace B330 expandable module with the initial launch to orbit in 2020 on ULA’s Atlas V 552 configuration launch vehicle.
The B330 will have 330 cubic meters (12,000 cu ft) of internal space. The craft will support zero-gravity research including scientific missions and manufacturing processes. Beyond its industrial and scientific purposes, however, it has potential as a destination for space tourism and a craft for missions destined for the Moon and Mars.
“We are exploring options for the location of the initial B330 including discussions with NASA on the possibility of attaching it to the International Space Station (ISS),” said Robert Bigelow, founder and president of Bigelow Aerospace. “In that configuration, the B330 will enlarge the station’s volume by 30% and function as a multipurpose testbed in support of NASA’s exploration goals as well as provide significant commercial opportunities. The working name for this module is XBASE or Expandable Bigelow Advanced Station Enhancement.”
