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 (firstname.lastname@example.org, 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, email@example.com, 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, firstname.lastname@example.org, 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, email@example.com, 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, firstname.lastname@example.org, 212-419-7550) A successful mission requires a well-planned supply strategy.
"Risky Business" by Elon Musk (Tekla S. Perry, email@example.com, 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 (firstname.lastname@example.org, 212-419-7920) Engineers rethink how to get to Mars and back.
"How To Go to Mars--Right Now!" by Robert Zubrin (Jean Kumagai, email@example.com, 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, firstname.lastname@example.org, 212-419-7559) Maybe--if it adopts a less top-down approach.
"Moonstruck" by William Sweet (email@example.com, 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, firstname.lastname@example.org, 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, email@example.com, 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 (firstname.lastname@example.org, 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, email@example.com, 212-419-7551) How do you justify human spaceflight?
"The Amazing Orbiting Garriotts" by Owen and Richard Garriott (Jean Kumagai, firstname.lastname@example.org, 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, email@example.com, 212-419-7556) Human exploration of the Red Planet will inspire new generations of engineers.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
