The universe is very large and our understanding of it very small. Despite the straitened U.S. economy and a crisis of confidence in other countries, there is an opportunity to push out further into the solar system.
Norm Augustine, former chairman of Lockheed Martin, is heading a panel that is expected, by August, to offer an opinion as to whether NASA's human spaceflight efforts are worth continuing or whether the emphasis should be shifted to unmanned exploration.
As the panel's members meet to discuss the pros and cons of various missions, astronauts, engineers, and other stakeholders are also debating over the hardware and software required for survival in space. In the June issue of IEEE Spectrum, experts and editors explain the rocket science (yes, it is rocket science) and related efforts behind the current and expected space programs in different countries.
Four hundred years ago, Galileo peered through his telescope. Forty years ago, Apollo astronauts took humanity's first baby step into the cosmos. Now it's time to take the next one.
"Introduction: Why Mars? Why Now?" by Susan Hassler (email@example.com, 212-419-7556) President Obama has yet to appoint a new administrator for NASA. That person will need to find funding, on top of the billions already spent, for a new launch vehicle for a return to the moon, as the first stage of a planned Mars mission sometime after 2030.
"Mars Is Hard" by Fred Guterl and Monica Heger (Jean Kumagai, firstname.lastname@example.org, 212-419-7551) Fifty years ago, space experts thought we'd be there by now. Here's why we're not.
"What To Wear on Mars" by Monica Heger (Jean Kumagai, email@example.com, 212-419-7551) Those bulky Apollo-era spacesuits are so yesterday.
"The Kind of People Who Will Go to Mars" by David A. Wolf (Susan Hassler, firstname.lastname@example.org, 212-419-7556) They won't lack fear--they'll be able to operate well in the face of it.
"What To Pack for Mars" by Olivier L. De Weck (Joshua J. Romero, email@example.com, 212-419-7550) A successful mission requires a well-planned supply strategy.
"Risky Business" by Elon Musk (Tekla S. Perry, firstname.lastname@example.org, 650-328-7570) Why Mars is more important than cosmetics and why a failed launch is also a partial success.
"Rockets for the Red Planet" by Sandra Upson (email@example.com, 212-419-7920) Engineers rethink how to get to Mars and back.
"How To Go to Mars--Right Now!" by Robert Zubrin (Jean Kumagai, firstname.lastname@example.org, 212-419-7551) Human exploration of Mars doesn't need to wait for advanced rockets, giant spaceships, or lunar base stations.
"Could China Get to Mars First?" by James Oberg (William Sweet, email@example.com, 212-419-7559) Maybe--if it adopts a less top-down approach.
"Moonstruck" by William Sweet (firstname.lastname@example.org, 212-419-7559) There's a palpable longing to go back, but does it make sense?
"It's Only Rocket Science" by Prachi Patel (Jean Kumagai, email@example.com, 212-419-7551) For the Carnegie Mellon team vying for the Google Lunar X Prize, failure to launch--and land--is not an option.
"India Joins League of Lunar Nations" by G. Madhavan Nair (Glenn Zorpette, firstname.lastname@example.org, 212-419-7580) The head of the Indian Space Agency talks about his country's first robotic lunar mission and plans for landing an Indian on the moon and Mars.
"Mars for the Rest of Us" by Joshua J. Romero (email@example.com, 212-419-7550) Better cameras, greater bandwidth, and bigger displays put Mars within reach of armchair explorers.
"The End of the Cult of the Astronaut" by David A. Mindell (Jean Kumagai, firstname.lastname@example.org, 212-419-7551) How do you justify human spaceflight?
"The Amazing Orbiting Garriotts" by Owen and Richard Garriott (Jean Kumagai, email@example.com, 212-419-7551) The second father-and-son pair to have traveled in space offer their thoughts on weightlessness, ham radio, and why the Space Station is like the movie Metropolis.
"The Mars Challenge" by Leah H. Jamieson with John Norberg (Susan Hassler, firstname.lastname@example.org, 212-419-7556) Human exploration of the Red Planet will inspire new generations of engineers.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
