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.

"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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
