Spinning to Mars The Space Review
Thirty years ago today a group of scientists, grad students, and all around Mars enthusiasts wrapped up the four-day Case for Mars conference in Boulder, Colorado. While there, they drafted plans for a human Mars spacecraft that became enshrined—at least for a little while—in popular culture. A large spinning vessel consisting of three nearly identical ships and their landing craft, it was a serious attempt at defining a human mission to Mars. By the early 1990s, one of the Case for Mars participants, Carter Emmart, produced a beautifully detailed model of the spinning spacecraft that was placed on display in the Smithsonian’s National Air and Space Museum in Washington, DC. Now, after a long absence, that model is back in public view.

Dropship offers safe landings for Mars rovers
The dramatic conclusion to ESA’s latest StarTiger project: a ‘dropship’ quadcopter steers itself to lower a rover gently onto a safe patch of the rocky martian surface. StarTiger’s Dropter project was tasked with developing and demonstrating a European precision-landing capability for Mars and other targets. The Skycrane that lowered NASA’s Curiosity rover onto Mars showed the potential of this approach, precisely delivering rovers to their science targets while avoiding rock fields, slopes and other hazards. “StarTiger is a fresh approach to space engineering,” explains Peter de Maagt, overseeing the project. “Take a highly qualified, well-motivated team, gather them at a single well-equipped site, then give them a fixed time to solve a challenging technical problem.”

Zubrin Challenges Chang Diaz to Debate at Mars Society Convention in Houston
Mars Society President Dr. Robert Zubrin has challenged Ad Astra President & CEO Dr. Franklin Chang Diaz to a debate at the 17th Annual International Mars Society Convention, which will be held in Ad Astra’s hometown of Houston, Texas August 7-10, 2014. The proposed debate proposition is: Resolved “Electric Propulsion in an Enabling Technology for Human Mars Exploration,” with Dr. Chang Diaz representing the affirmative side and Dr. Zubrin the negative side. Commenting on the challenge, Dr. Zubrin said, “This debate is critically necessary. Dr. Chang Diaz has been actively propagandizing an argument combining three claims. First, that cosmic radiation hazards dictate that current day propulsion, which enables six month transits from Earth to Mars, is too slow to enablehuman mission to Mars. Second, that therefore much faster forms of interplanetary propulsion are necessary before we dare undertake human Mars exploration missions. Third, that his VASIMR propulsion system would uniquely enable such quick trips.

Mars Technologies Spawn Durable Wind Turbines
In the early 1990s, NASA was planning for an extended stay on Mars, and Bubenheim and his Ames colleagues were concentrating efforts on creating a complete ecological system to sustain human crewmembers during their time on the Red Planet. “The main barrier to developing such a system,” he says, “is energy.” Mars has no power plants, and a regenerative system requires equipment that runs on electricity to do everything from regulating humidity in the atmosphere to monitoring the quality of recycled water. The Ames group started looking at maximizing energy use efficiency and alternative methods to make power on a planet that is millions of miles away from Earth. They turned to a hybrid concept combining two renewable sources: wind and solar power technologies. Large surface temperature swings on Mars produce windy conditions; extreme examples are the frequent dust storms that can block nearly all sunlight. “When there’s a dust storm and the wind is blowing, the wind system could be the dominant power source. When the wind is not blowing and the sun is shining on the surface, photovoltaics could be the dominant source,” says Bubenheim.

NASA to test giant supersonic Mars parachute off Hawaiian coast CBS News
The skies off the Hawaiian island of Kauai will be a stand-in for Mars as NASA prepares to launch a saucer-shaped vehicle in an experimental flight designed to land heavy loads on the red planet. For decades, robotic landers and rovers have hitched a ride to Earth's planetary neighbor using the same parachute design. But NASA needs a bigger and stronger parachute if it wants to send astronauts there. Weather permitting, the space agency will conduct a test flight Tuesday high in Earth's atmosphere that's supposed to simulate the thin Martian air. Cameras rigged aboard the vehicle will capture the action as it accelerates to four times the speed of sound and falls back to Earth. Viewers with an Internet connection can follow along live.

This Spacesuit for Exploring Mars Is a Form-Fitting Math Problem Wired
In science fiction, from 2001: A Space Odyssey to Ender’s Game, astronauts zip around zero-g environments clad in stylish, skin-tight spacesuits. In reality, outfits designed for outer space are bulky, hard to maneuver, and have all the charm of adult diapers. Even their name, Extravehicular Mobility Units, or EMUs, is clumsy. Enter Dava Newman, fashion designer to the stars. You won’t see her work on the red carpet, but if this MIT professor has her way, all the most fashionable space explorers will be wearing her designs when they set foot on the red planet.

NASA Designs a Robot for Mars Product Design & Development
Valkyrie stands more than six feet tall, weighs 286 pounds, and has an 80 inch wingspan. “It feels human-like, you can look her in the eyes,” says Reg Berka, deputy project manager of Valkyrie, the NASA built robot destined for the red planet. Designed at the NASA Johnson Space Center (JSC), Valkyrie competed in the DARPA Robotics Challenge (DRC) [See sidebar] trial round in December 2013, with hopes of one day setting foot on Mars.

The NASA Z-2 Suit Voting Now Open
After the positive response to the Z-1 suit's visual design we received, we wanted to take the opportunity to provide this new suit with an equally memorable appearance. The cover layer of a prototype suit is important as it serves to protect the suit against abrasion and snags during the rigors of testing. With the Z-2, we're looking forward to employing cover layer design elements never used in a spacesuit before. The designs shown were produced in collaboration with ILC, the primary suit vendor and Philadelphia University. The designs were created with the intent to protect the suit and to highlight certain mobility features to aid suit testing. To take it a step further, we are leaving it up you, the public, to choose which of three candidates will be built. Voting is open through April 15, 2014 at 11:59pm EDT.

Supersonic Jet Ditches Windows for Massive Live-Streaming Screens Wired
Spike Aerospace is in the midst of building the first supersonic private jet. And when the $80 million S-512 takes off in December 2018, it won’t have something you’d find on every other passenger aircraft: windows. The Boston-based aerospace firm is taking advantage of recent advances in video recording, live-streaming, and display technology with an interior that replaces the windows with massive, high-def screens. The S-512’s exterior will be lined with tiny cameras sending footage to thin, curved displays lining the interior walls of the fuselage. The result will be an unbroken panoramic view of the outside world. And if passengers want to sleep or distract themselves from ominous rainclouds, they can darken the screen or choose from an assortment of ambient images. But this isn’t just a wiz-bang feature for an eight-figure aircraft. While windows are essential for keeping claustrophobia in check, they require engineering workarounds that compromise a fuselage’s simple structure. And that goes two-fold for a supersonic aircraft. An airplane is stronger sans windows, which is one of the reasons why planes carrying military personnel or packages fly without them. Putting passenger windows on an airplane requires meticulous construction — the ovular shape, small aperture, and double-pane construction are all there to maintain cabin pressure and resist cracking while flying 500 mph at 35,000 feet. It would be much simpler and safer to have a smooth-skinned, window-less fuselage, but frequent fliers have become accustomed to a calming view of the clouds and tiny cities during takeoff and landing.

How Marscoin can help fund the first colony in the Solar System Marscoin.org
The more people that adopt Marscoin and use it in their daily lives, the more the early stake-holders, in this case MarsOne, would benefit and grow in value and thus quite naturally be able to fund the development of the first Mars colony. Just by using Marscoin private individuals would participate in the biggest kickstarter project of all times, funding themselves and mankind's first colony on another planet. Just by using Marscoin, the first extra-terrestrian colony in the Solar System could be boostrapped. As of Jan. 2014 the market cap of Bitcoin is 10 billion, Litecoin 0.5 billion and Dogecoin 10 million USD - any growth in Marscoin will bring humans closer to taking a step among the stars.

The spacesuit inspired by medieval armor, made for walking on Mars
It takes Dr Gernot Groomer three hours to put on the spacesuit he hopes will, one day, walk across the surface of Mars. It's worth taking time when you're wearing a suit made from roughly 10,000 parts, designed for the most treacherous environment yet to be encountered by a human being. Groomer is the Austrian astrobiologist responsible for building a spacesuit for the Mars explorers of tomorrow -- and he's taking inspiration from armor worn by medieval knights. He explains that -- after the titanic effort required to get there -- simply surviving on the red planet will be a grueling battle.

This Sleek Spiderman Spacesuit Could Take Astronauts To Mars Co.Exist
Even though they perform superhuman feats, astronauts always look a little ridiculous. Their clunky pressurized spacesuits are functional--they provide oxygen, scrub CO2, and keep astronauts safe from the elements--but they aren't exactly well-suited for the kind of intensive exploration that astronauts will conduct when humans finally reach Mars. Dava Newman, a speaker at this year's TEDWomen event in San Francisco, has spent more than a decade working on a sleeker, better spacesuit for Mars exploration. The MIT aerospace engineering professor's Spiderman-like "BioSuit" will finally make astronauts look sexy, and ensure that they can explore difficult terrain without tripping over the bulk of the nearly 300-pound suit in use today.

Historic Demonstration Proves Laser Communication Possible
In the early morning hours of Oct. 18, NASA’s Lunar Laser Communication Demonstration (LLCD) made history, transmitting data from lunar orbit to Earth at a rate of 622 Megabits-per-second (Mbps). That download rate is more than six times faster than previous state-of-the-art radio systems flown to the moon. “It was amazing how quickly we were able to acquire the first signals, especially from such a distance,” said Don Cornwell, LLCD manager. “I attribute this success to the great work accomplished over the years by the Massachusetts Institute of Technology Lincoln Laboratory (MIT/LL) and their partnership with NASA.”

World Space Walk simultaneously puts three Mars-capable spacesuits to the test Gizmag
On October 8, three teams in various parts of the world participated in an unprecedented simultaneous test of three experimental spacesuits. Coordinated from a mission control center in Innsbruck, Austria run by the Austrian Space Forum (OeWF), World Space Walk 2013 aims at setting standards for developing suits for the future exploration of the planet Mars. "If we are going to prepare for a human mission to Mars in the future, we need to have as much knowledge as possible on the practicalities and limitations of working in spacesuits on planetary terrains," says Gernot Groemer, the President of the Austrian Space Forum. "For World Space Walk 2013, we have had the amazing opportunity to work with four different teams who are developing spacesuits and to collaborate on the same set of tasks. This technical test is a simple, yet important, first milestone to compare different analogue suit systems worldwide and to contribute to a growing area of research."

Quick Fusion-Powered Trips to Mars No Fantasy, Scientists Say
Sending astronauts to Mars aboard a superfast spacecraft powered by nuclear fusion may seem like a sci-fi dream, but it's entirely attainable, scientists say. The physics behind a fusion-driven rocket have been demonstrated in the laboratory, so such a device may well be propelling people on 90-day trips to the Red Planet in a matter of decades, according to a team of researchers working on the technology. "This is a reality, basically," Anthony Pancotti, of the space-propulsion company MSNW, said Sept. 25 during a presentation with NASA's Future In-Space Operations working group. "Fusion occurs in the sun, and also in our labs."
