How NASA Solved a $100 Million Problem for Five Bucks

Tue, 31 Jan 2012 12:58:21 -0800

A few years ago, back when the Constellation Program was still alive, NASA engineers discovered that the Ares I rocket had a crucial flaw, one that could have jeopardized the entire project. They panicked. They plotted. They steeled themselves for the hundreds of millions of dollars it was going to take to make things right. And then they found out how to fix it for the cost of an extra value meal. The problem facing Ares 1 wasn't a booster malfunction or a computer glitch. It was simple cause-and-effect physics. During the final stages of a launch, as the solid booster rocket burns down it makes the entire vehicle oscillate rapidly. Add that oscillation to the resonant frequency of the large tube that separates the booster and the crew cabin, and you get a crew capsule that vibrates like crazy. When humans are vibrating to that extent, it's impossible for them to read a digital display. If the astronauts can't read, they can't do their jobs. If they can't do their jobs, no more mission.

Op/Ed: How Much Is an Astronaut’s Life Worth?

Sun, 29 Jan 2012 00:08:07 -0800

If we could put a man on the Moon, why can’t we put a man on the Moon? Starting with near zero space capability in 1961, the National Aeronautics and Space Administration (NASA) put men on our companion world in eight years. Yet despite vastly superior technology and hundreds of billions of dollars in subsequent spending, the agency has been unable to send anyone else farther than low Earth orbit ever since. Why? Because we insist that our astronauts be as safe as possible.

Mars-Bound Instrument Detects Solar Burst's Effects

Fri, 27 Jan 2012 14:40:15 -0800

The largest solar particle event since 2005 has been detected by the radiation- monitoring instrument aboard the Mars Science Laboratory spacecraft, on its way from Earth to Mars. The Radiation Assessment Detector, inside the mission's Curiosity rover tucked inside the spacecraft, is measuring the radiation exposure that could affect a human astronaut on a potential Mars mission. It has measured an increase resulting from a Jan. 22 solar storm observed by other NASA spacecraft. No harmful effects to the Mars Science Laboratory have been detected from this solar event.

SLS Exploration Roadmap evaluations provide clues for human Mars missions

Tue, 24 Jan 2012 22:05:49 -0800

As NASA managers continue to work through the evaluations into an exploration roadmap for the agency, the end goal of sending humans to Mars is starting to show a level of consistency. Per documentation, the key Design Reference Mission (DRM) evaluations are pointing to the “Flexible Path” approach of visiting a Martian moon, prior to landing humans on Mars itself.

Research participants sought for 120-day Mars analog habitat study

Sun, 22 Jan 2012 14:12:29 -0800

Researchers from the University of Hawaiʻi at Mānoa and Cornell University are seeking applicants for a NASA-funded Mars analog habitat study, Hawaiʻi Space Exploration Analog and Simulation, or HI-SEAS. The study will investigate the impact of food preparation, food monotony, nasal congestion and smelling acuity on food and nutrient intake in isolated, confined microsocieties similar to astronaut crews on long term planetary exploration missions. The study will also track the use of habitat resources related to cooking and eating, to provide data for future designs of planetary habitats. Eight research participants are sought for the analog portion of the study: six to form the habitat crew, one “ground-based” research support specialist to provide support for the experiments from outside the habitat, and one more individual to serve as a backup for the other seven. Crewmembers in the analog portion of the study will spend four months living and working in a Mars analog habitat, wearing “spacesuits” whenever they need to venture outside. They will consume a diet including both freeze-dried and dehydrated foods similar to present-day astronaut foods, plus foods that they prepare themselves from shelf-stable supplies – an alternative approach to feeding crews of long term planetary outposts. The deadline for applications is February 29, 2012. To apply, visit: http://www.manoa.hawaii.edu/hi-seas.

Most important scientific study ever: What about farting astronauts?

Sun, 15 Jan 2012 22:44:58 -0800

Humans produce two flammable gases: hydrogen and methane. Flammable gases accumulate in an enclosed space and can ignite. Astronauts are humans who spend lots of time in enclosed space. The logic is irrefutable. So, what's the risk to farting astronauts?

Palestine students work with NASA on future Martian colony

Sun, 15 Jan 2012 18:19:46 -0800

It’s not every day that middle school students get a chance to talk to NASA engineers — learning about space exploration to Mars in particular. Thanks to a pilot program brought to Palestine Independent School District by ICEE Success (Institute where Creativity Empowers Education Success), David Delgado, outreach coordinator for NASA’s Mars Public Engagement Team and the Imagine Mars project creative lead, made a special visit to Palestine Middle School classes involved in the pilot program Thursday. The Imagine Mars project is a national arts, sciences and technology education initiative, where students, scientists and civic leaders are working to design a sustainable Mars community.

We will colonise Mars in 100 yrs: Stephen Hawking

Sat, 07 Jan 2012 11:53:39 -0800

Professor Stephen Hawking, who has decoded some of the greatest mysteries of the universe, predicted that humans will colonise Mars - but not for at least a century. The physicist said it is 'essential' for man to spread across the galaxy in case Earth is destroyed suggesting that it was 'almost certain' that a disaster 'such as nuclear war or global warming' would obliterate the planet within a thousand years. "It is essential that we colonise space. I believe that we will eventually establish self-sustaining colonies on Mars and other bodies in the solar system, but not within the next 100 years," the Daily Mail quoted Professor Hawking as telling BBC Radio 4's Today programme on the eve of his 70th birthday.

Man Will Be on Mars in 20 Years—for Less Than $5 Billion, Says Elon Musk

Thu, 29 Dec 2011 23:17:04 -0800

Elon Musk, the man who helped make Internet commerce possible for the everyman by creating PayPal, wants to bring space travel to the masses as well. And not that just putting a proverbial foot in space and then returning right away to Earth. Musk hopes his private space company SpaceX will bring millions to Mars. Says the New Scientist’s Greg Klerkx: In his Heinlein prize acceptance speech, he said he wants to put 10,000 people on Mars. Musk rarely makes public statements merely for effect but a call for 10,000 would-be Martians is extraordinary, even by his standards. When I query him on this point, he pauses. Is he reconsidering? Yes... but, as with so much else about Musk, not in a predictable way. "Ultimately we don't really want 10,000 people on Mars," he says, after letting the pause linger a few seconds more. "We want millions."

Mission to Mars: NASA gears up to send robotic laboratory and laser-armed rover to red planet

Mon, 14 Nov 2011 14:32:03 -0800

Nasa’s most advanced mobile robotic laboratory, which will examine one of the most intriguing areas on Mars, is in final preparations for a launch from Florida's Space Coast on November 25. The Mars Science Laboratory mission will carry Curiosity, a rover with more scientific capability than any ever sent to another planet. It will set down inside a huge crater and use its highly advanced instruments, including cameras and lasers, to find out more about the planet’s environment, which will help pave the way for human missions. Doug McCuistion, director of the Mars Exploration Program at Nasa Headquarters in Washington, said: ‘Mars Science Laboratory builds upon the improved understanding about Mars gained from current and recent missions. ‘This mission advances technologies and science that will move us toward missions to return samples from, and eventually send humans to, Mars.’

Mars explorers will include women, experts say

Fri, 11 Nov 2011 09:57:02 -0800

Men walked on the Moon, but women will be among the pioneering explorers who someday step foot on Mars, said a gathering of top female space experts this week. Plenty has changed since Neil Armstrong and 11 male successors left their footprints on the Moon from 1969 to 1972, but lingering stereotypes still harm young girls and not enough women reach the upper levels of planetary science, they said. Some of the leading women at NASA, Lockheed Martin, SpaceX and other organizations came together for a two-day meeting in the nation's capital to discuss their work, how they made it and how the next generation can, too. Despite challenges that may remain, the days when women were excluded from space exploration are over, said Colleen Hartman, NASA assistant associate administrator, science mission directorate. "Men went to the Moon but everyone will be going to Mars."

6 Mock Mars Explorers Emerge from 520-Day Virtual Mission

Fri, 04 Nov 2011 16:33:06 -0800

After being isolated from the rest of the world for nearly a year and a half, sealed away in a mock spacecraft, six volunteer astronauts "returned" to Earth today (Nov. 4) to end a simulated mission to Mars and back. The hatch of the pretend Mars500 spaceship, which is actually a special isolation facility at the Russian Institute for Biomedical Problems in Moscow, was opened at 6 a.m. EDT (1000 GMT) this morning to mark the successful completion of a 520-day simulated journey to the Red Planet. The six volunteer crew members had been living and working in the Mars500 facility since June 2010. The international Mars500 crew is made up of Italian engineer Diego Urbina, French engineer Romain Charles, Russian physiologist Alexandr Smoleevski, Russian surgeon Sukhrob Kamolov, Russian engineer Alexey Sitev and Chinese astronaut trainer Wang Yue.
