NASA has, on a number of occasions tapped the NewSpace firm Virgin Galactic to help the space agency accomplish its objectives – recently, it has done so again. This new contract will see NASA science payloads take suborbital flights on the company’s SpaceShipTwo (SS2) spacecraft. This however is not the first time that NASA has entered into an arrangement with the emerging commercial space flight firm.
NASA first began working with Virgin Galactic in 2007, when it entered into a Memorandum of Understanding to explore possible collaborative efforts to develop various equipment required to conduct space flight operations (space suits, heat shields, and other space flight elements). Under this arrangement NASA will have one scientific mission flown aboard SpaceShipTwo with options for two additional flights. Photo Credit: Virgin Galactic/Mark Greenberg
Earlier this year, NASA selected seven different firms that either had or were developing suborbital spacecraft – one of these was Virgin Galactic. The announcement that was made Thursday, Oct. 13 is actually the culmination of the Flight Opportunities Program, which was announced on Aug. 9 of this year and established to help NASA meet its technology and research development requirements.
The agreement to fly NASA payloads on SS2 was announced about a week after former NASA Shuttle Program Manager; Mike Moses stated he was leaving the space agency to work as Virgin Galactic’s vice president of operations. Moses will be in charge of all operations at Spaceport America, located near Las Cruces, New Mexico. On these missions, not only will a carry a scientific payload but an engineer that will monitor the payload and operate the payload. Photo Credit: Virgin Galactic/Mark Greenberg
“I’ve known Mike for a long time, from his flight controller days which led to him becoming a flight director and then moving into the shuttle program,” said Kyle Herring, a NASA public affairs officer. “I think he would be a very valuable asset to any organization that he went to. Mike’s expertise will be very beneficial in not just mission operations but ground operations as well.”
The NASA contract with Virgin Galactic is for one flight with the space agency optioning two additional flights (for a potential of three flights total). If NASA options all three flights, the total contract would be worth an estimated $4.5 million. The announcement came just four days prior to the dedication ceremony for the spaceport’s new headquarters (the dedication was on Monday, Oct. 17).

Each of these suborbital missions will have a trained engineer on board to handle the experiments.
Virgin Galactic is an arm of the London-based Virgin Group which is owned by British billionaire Sir Richard Branson. Virgin Galactic is working to provide tourists with suborbital flights into space that will allow these space passengers to briefly experience the micro-gravity environment. The flights will launch from a spaceport which is currently under construction near Las Cruces New Mexico. Tickets have been priced at about $200,000 each.

The X-37, versions of which have flown twice into space already, is now being proposed as a potential means of transportation for crews to the International Space Station. Photo Credit: Boeing

As reported online at Space.com, the Boeing Company is already working on the CST-100 space taxi as a means of transportation to and from the International Space Station (ISS). But the aerospace firm is not content with just this simple space capsule and is looking into whether-or-not another of Boeing’s current offerings – the X-37B space plane could be modified to one day ferry crew to and from the orbiting laboratory as well.
proposed variant of the spacecraft, dubbed the X-37C, is being considered for a role that has some similarities to the cancelled X-38 Crew Return Vehicle (CRV). The announcement was made at a conference hosted by the American Institute of Aeronautics and Astronautics (AIAA) and reported on Space.com.

The X-37B or Orbital Test Vehicle (OTV) has so far been launched twice by the U.S. Air Force from Cape Canaveral Air Force Station in Florida. One of the military space planes completed the craft’s inaugural mission, USA-212, on Apr. 22, 2010. The mini space plane reentered Earth’s atmosphere and conducted an autonomous landing at Vandenberg Air Force on Dec. 3, 2010.
The U.S. Air Force then went on to launch the second of the space planes on mission USA-226 on Mar. 5, 2011. With these two successful launches, the longest-duration stay on orbit by a reusable vehicle and a landing under its belt, some of the vehicle’s primary systems (guidance, navigation, thermal protection and aerodynamics among others) are now viewed as having been validated. The vehicle has performed better than expected with the turnaround time being less than predicted.
If the X-37C is produced, it will be roughly twice the size of its predecessor. The X-37B is about 29 feet long; this new version of the mini shuttle would be approximately 48 feet in length. The X-37C is estimated at being approximately 165-180 percent larger than the X-37B. This increase in the size requires a larger launch vehicle.
This larger size also highlights plans to have the spacecraft carry 5 or 6 astronauts – with room for an additional crew member that is immobilized on a stretcher. The X-38, manufactured by Scaled Composites, was designed, built and tested to serve as a lifeboat for the ISS. In case of an emergency, crew members on the ISS would have entered the CRV and returned to Earth – a role that now could possibly be filled by the X-37C. The key difference being that the CRV only reached the point of atmospheric drop tests – the X-37B has flown into space twice.

The crewed variant of the X-37 space plane would contain a pressurized compartment where the payload is normally stored, it would have a hatch that would allow for astronauts to enter and depart the spacecraft. Another hatch would be located on the main body of the mini shuttle so as to allow access to the vehicle on the ground. The X-37C, like its smaller cousin, would be able to rendezvous, dock, reenter the atmosphere and land remotely, without the need of a pilot. Acknowledging the need for pilots to control their own craft however, the X-37C would be capable of accomplishing these space flight requirements under manual control as well.
As mentioned in the Space.com article, one of the other selling points for the X-37C is its modular nature. Different variants could be used for crewed flights or unmanned missions that could return delicate cargo from the ISS. Neither the Russian Soyuz spacecraft, nor commercially-developed capsules are considered as appropriate means of returning biological or crystal experiments to Earth due to the high rate of acceleration that these vehicles incur upon atmospheric reentry. By comparison the X-37B experiences just 1.5 “g” upon reentry.
The launch vehicle that would send the proposed X-37C to orbit would be the United Launch Alliance Atlas V rocket. In provided images the X-37C is shown utilizing a larger version of the Atlas booster and without the protective fairing that covered the two X-37B space planes that were launched.
Editor’s note: This guest post was written by Andy Tomaswick, an electrical engineer who follows space science and technology.
Imagine a rover on the Moon nimbly gliding around boulders and crevices until it finds something that looks interesting. It stops to pick up a sample and then rushes back to its home platform only to venture out again soon. Now imagine that it was doing all of this without any humans telling it to.
That’s the idea behind NASA’s new Sample Return Robot Challenge, part of its Centennial Challenge program. The space agency announced a potential $1.5 million prize for what it terms “an autonomous robotic system to locate and collect a set of specific sample types from a large planetary analog area and then return the samples to the starting zone.”
NASA recently released a set of rules that requires the participating robots to go big. Like 80,000 square meters big. That’s the amount of area of rough terrain, complete with trees and creeks, the autonomous bots will have to cover in order to find different samples spread randomly throughout.
Teams will collect those samples during two different levels of competition. Level one will require the participants to retrieve a randomly placed sample with a distinct packaging. The second level, and the one that pays the most cash prizes, requires the recovery of different types of samples, including ones specifically designed to test a team’s pattern recognition skills.
The competition is open to everyone and teams have until the end of the year to register. The event is expected to be held next year at Worcester Polytechnic Institute in Massachusetts. If one a team manages to win the prize, NASA’s dream of autonomous rovers won’t be too far off.

It’s been a tenet of the standard model of physics for over a century. The speed of light is a unwavering and unbreakable barrier, at least by any form of matter and energy we know of. Nothing in our Universe can travel faster than 299,792 km/s (186,282 miles per second), not even – as the term implies – light itself. It’s the universal constant, the “c” in Einstein’s E = mc2, a cosmic speed limit that can’t be broken.
That is, until now.
An international team of scientists at the Gran Sasso research facility outside of Rome announced today that they have clocked neutrinos traveling faster than the speed of light. The neutrinos, subatomic particles with very little mass, were contained within beams emitted from CERN 730 km (500 miles) away in Switzerland. Over a period of three years, 15,000 neutrino beams were fired from CERN at special detectors located deep underground at Gran Sasso. Where light would have made the trip in 2.4 thousandths of a second, the neutrinos made it there 60 nanoseconds faster – that’s 60 billionths of a second – a tiny difference to us but a huge difference to particle physicists!
The implications of such a discovery are staggering, as it would effectively undermine Einstein’s theory of relativity and force a rewrite of the Standard Model of physics.

“We are shocked,” said project spokesman and University of Bern physicist Antonio Ereditato.
“We have high confidence in our results. We have checked and rechecked for anything that could have distorted our measurements but we found nothing. We now want colleagues to check them independently.”
Neutrinos are created naturally from the decay of radioactive materials and from reactions that occur inside stars. Neutrinos are constantly zipping through space and can pass through solid material easily with little discernible effect… as you’ve been reading this billions of neutrinos have already passed through you!
The experiment, called OPERA (Oscillation Project with Emulsion-tRacking Apparatus) is located in Italy’s Gran Sasso facility 1,400 meters (4,593 feet) underground and uses a complex array of electronics and photographic plates to detect the particle beams. Its subterranean location helps prevent experiment contamination from other sources of radiation, such as cosmic rays. Over 750 scientists from 22 countries around the world work there.
Ereditato is confident in the results as they have been consistently measured in over 16,000 events over the past two years. Still, other experiments are being planned elsewhere in an attempt to confirm these remarkable findings. If they are confirmed, we may be looking at a literal breakdown of the modern rules of physics as we know them!
“We have high confidence in our results,” said Ereditato. “We have checked and rechecked for anything that could have distorted our measurements but we found nothing. We now want colleagues to check them independently.”
A preprint of the OPERA results will be posted on the physics website ArXiv.org.
NASA has announced that it will option additional milestones for its Commercial Crew Development Program. Image Credit: SNC

By all reports – commercial space is thriving. A number of recent announcements show that the burgeoning “private” space industry is thriving. NASA released its plans to obtain transportation services for its astronauts to the International Space Station (ISS) as well as optional milestones for the Commercial Crew Development Round 2 (CCDev2).
“This is a significant step forward in America’s amazing story of space exploration,” said NASA Administrator Charles Bolden. “It’s further evidence we are committed to fully implementing our plan — as laid out in the Authorization Act — to outsource our space station transportation so NASA can focus its energy and resources on deep space exploration.”
To help speed up the process Bolden has stated that NASA will fund some of the original milestones that have already been negotiated as part of some of the Space Act Agreements (SAA) under CCDev2.
NASA’s proposal outlines contracts that would benefit multiple firms that are set to provide the space agency with designs of spacecraft, rockets and other launch services. This contract is worth an estimated $1.61 billion and is currently slated to run from July 2012 through April 2014. NASA has updated Sierra Nevada Corporation’s SAA with four more milestones – that total up to $25.6 million meaning that the contract that this NewSpace firm now has with NASA is worth $105.6 million – if the agency can successfully accomplish all of its milestones.
“All four CCDev2 partners are performing very well and meeting their milestones,” said Phil McAlister, director of NASA’s Commercial Spaceflight Development. “These additional milestones were selected because they sufficiently accelerated the development of commercial crew transportation systems to justify additional NASA investment.”

Meanwhile, out in California, The Spaceship Company (TSC), the joint venture of Sir Richard Branson’s Virgin Galactic and Scaled Composites, announced a milestone of their own with the opening of its Final Assembly, Integration and Test Hangar (FAITH), at the Mojave Air and Space Port. The hangar, which cost an estimated $8 million, supports the final stages of Virgin Galactic’s WhiteKnightTwo and SpaceShipTwo. It is hoped that this new facility will both support further commercial space ventures and create jobs.
The facility is located on taxiway-B and encompasses approximately 68,000-square-feet. It will be used to assemble, prepare and test the vehicles. One of the building’s other roles is that of maintenance hangar.
“We take great pride in the opening of FAITH as an accomplishment for our company, our current and future customers and our industry,” said The Spaceship Company Vice President, Operations Enrico Palermo. “Within this new facility, we will produce the highest quality commercial spaceflight systems.”
With FAITH in place, the required infrastructure is now in place to manufacture a fleet of SpaceShipTwo (SS2) sub-orbital spaceships as well as the WhiteKnightTwo (WK2) carrier aircraft. The facility has been sized to support construction of SS2 and WK2 with room to build two of each of these craft – at the same time.
The other structure that is needed to support SS2 and WK2 operations is a 48,000-square-foot building that is located at the Mojave Air and Space Port that TSC has recently had upgraded. If the sub-orbital space tourism market takes off TSC has optioned rights to expand the facility.
“Despite the current state of the U.S. economy and rising unemployment, this is a strong time of growth for The Spaceship Company,” Palermo said. “We are creating excellent, high-skilled job opportunities for individuals with aerospace, engineering and hands-on space program experience. We want employees who are passionate about developing new and innovative ways of accessing space.”

Staying on the topic of sub-orbital space planes, Space Expedition Curaçao (SXC) and XCOR Aerospace, Inc. have announced the completion of a deal that will secure the wet lease of production Lynx tail number two for operation on the Caribbean island of Curaçao.
“Since we signed the initial Memorandum of Understanding (MOU) in October of 2010, XCOR and SXC have worked diligently towards completing the Definitive Agreement,” explained XCOR CEO Jeff Greason. “Now that the ink is dry and the check has cleared we can proceed at full pace to begin operations in Curaçao in 2014.”
Since the first flights of SpaceShipOne high above the Mojave Desert, the commercial space industry has found its legs and has expanded its reach both nationally and internationally. With Space Exploration Technologies (SpaceX) plans to launch its next Falcon 9 rocket and Dragon spacecraft to the International Space Station in November the commercial space field appears to be cementing its beachhead on not only sub-orbital flights – but orbital ones as well.

It is looking less likely that Space Exploration Technologies (SpaceX) will be allowed to dock the next of its Dragon Spacecraft to the International Space Station (ISS). Instead it is now looking like the Dragon will be allowed to only come close the orbiting outpost to test out many of the spacecraft’s key systems.
This comes from a statement issued by Vladimir Solovyov, head of the Russian segment of the ISS mission control center on Friday and posted on the Russian news site RIA Novosti. Up until now SpaceX has stated that they would launch the next Dragon Spacecraft atop one of the company’s Falcon 9 rockets on Nov. 30. It is unknown now whether-or-not the proposed docking will be allowed to take place.

In a company-prepared statement, SpaceX stated that the company had been working to fulfill all of the necessary requirements to allow SpaceX to become the first private firm to dock its spacecraft with the ISS. Russia, however, has repeatedly stated that it will not allow this. The rationale behind this stance is based on safety. According to Russia, a vehicle, which has only flown once, does not have the established, proven track record required for such operations.
Moreover both NASA and SpaceX stated that while a final determination has yet to be made – the private space firm has not been denied the opportunity to dock with the International Space Station. Thus leaving the flight’s status in a sort of limbo. This situation also highlights that the assorted international members involved on ISS – don’t always agree.

Many industry experts noted the irony of these statements given that the last Soyuz rocket failed, causing the destruction of the Progress spacecraft as well as the three tons of supplies that the spacecraft carried.
NewSpace firms themselves have acknowledged anomalies in their programs – including SpaceX. Blue Origin recently lost one of its test vehicles. Apparently the rocket went off of its predicted flight path and range safety was forced to destroy the vehicle.

Under the initial Commercial Orbital Transportation Services (COTS) agreement SpaceX was supposed to launch the Demo 2 mission, which would have completed COTS Milestone 19 (the mission scheduled for this November) two years ago. Similarly, milestones 20-22 were scheduled to be accomplished by the first quarter of 2010.
COTS is a NASA-funded program, designed to coordinate delivery of both astronauts as well as cargo to the ISS by privately-owned companies. COTS – was announced in January of 2006, under the Bush Administration. As it stands currently, SpaceX is the frontrunner under this contract which also includes Orbital Sciences Corporation.
Astronaut: Moon, Mars and Beyond. Need image credit data

These days, nearly every game company is trying to get their fingers in the MMORPG (Massively Multiplayer Online Role Playing Game) pie. Given the past successes of games like Ultima Online and Everquest and the current success of games like EVE Online and World of Warcraft, it’s no surprise that companies want try to create the next “killer app” of the MMORPG market.
One such game company that will be launching a new game is the company partnered with NASA to develop a space-based MMORPG for the space agency. Having raised nearly $40,000 in pledged funding via kickstarter, the company aims to start beta testing their offering some time next year.
So what does this new MMORPG do differently that will attract and retain paying customers? What makes Astronaut: Moon, Mars and Beyond different from say, EVE Online, Star Trek Online, or Star Wars Galaxies?
When a game developer becomes associated with a “big-name” property, expectations from both fans and developers can be quite high. Despite securing a license to create a game based on the Stargate franchise, a game development company never released the game and eventually ended up in bankruptcy. Star Trek Online, despite being one of the most anticipated MMORPG franchises went through two developers and when finally released had less than stellar sales. Of course, many fans of MMORPG’s are all too familiar with the myriad issues that plagued Star Wars Galaxies.
Not all online games are destined for failure. Some games build up players steadily over time and retain an extremely loyal fan base. In some cases, “slow and steady wins the race” is a reality for some game companies. So, what does it take to build a successful online game franchise?

In the case of the upcoming NASA MMORPG, Daniel Laughlin, project manager of NASA’s Learning Technologies cited research over the past decade indicating that games have tremendous potential to enhance learning. Laughlin stated, “The goal of the MMO project is to tap into the power of games to inspire and promote learning specifically in areas of science, technology, engineering and mathematics (STEM)”. Laughlin also added, “Based on the existing literature as well as my own experiences gaming, an MMO was the logical choice for a game project for NASA.”
What Laughlin believes to be of benefit to his idea is that a MMO gives the ability to continually update, adjust and expand a game – keeping players engaged over long periods of time.
Laughlin also mentioned the success of a NASA proof-of-concept game, Moonbase Alpha, as an encouraging sign of interest in a NASA-themed MMORPG, citing over 400,000 downloads. Laughlin also added “It is short proof of concept piece. Just a 20 minute mission, but it was built to prove to NASA that we could build a commercial quality game that uses NASA content – the lunar architecture – and is fun and inspirational.”

How does a promising proof-of-concept demo become a full-fledged online game?
Laughlin’s office solicited development partners to build the game under a non-reimbursable space act agreement (Meaning NASA is partnered with the game developer, but no funds change hands). The Astronaut: Moon, Mars and Beyond team was selected through a competitive process and has signed an agreement with NASA. The development team has to raise development funds on their own and NASA will provide subject matter experts along with education and evaluation experts to assist the team. Currently, the development team has raised nearly $40,000 via their kickstarter page.

Khal Shariff, CEO of Project Whitecard is equally optimistic about Astronaut: Moon, Mars and Beyond, stating, “We view this project as an almost sacred opportunity to engage new and current generations of science fans, those who are forever looking outward, with a vision for space exploration.”
When asked specifically about the fund raising efforts via Kickstarter, Shariff mentioned “It means all of the world to the people making this project happen, and it’s a hell of a deal, especially when you see that a $30 bid will send two licenses to a school and one to yourself.” Shariff also added, “More than this, it shows that Astronaut: Moon, Mars and Beyond, has honest, people-driven roots and will succeed or fail on its own merits.”

Shariff’s goal is a very solid game mechanic that rewards players for competing in areas of STEM learning and mentioned that one essential gameplay mechanic is a combination of gear and crafting. One other game play mechanic of quests are standard fare in many online games. In the case of Astronaut: Moon, Mars and Beyond, the quests are missions that fit into the larger storyline. Shariff was tight-lipped as to what, if any protagonists are present in the game, stating: “We have protagonists in the game, and I won’t say much about them, because I don’t want to spoil the opening scene of Chapter One.”
On the topic of chapters, Shariff mentioned plans for a future expansion to allow manned travel to destinations beyond Mars and the asteroid belt, even though in first chapter, players will have visited said destinations with unmanned missions.
Based on information presented by the development team, it does appear they will be putting forth considerable effort to fulfill Laughlin’s goal of a fun, educational and infinitely playable game. Shariff concluded with: “We want you to sit down and curl up with one session and have a feeling like you had when you read the best short science fiction stories, especially like those of Clarke. There is plenty of adventure to plumb.”

A Dictionary of the Space Age covers most aspects of space flight but is somewhat lacking in detail. Image Credit: John Hopkins University & Alan Walters/awaltersphoto.com

Writing a dictionary is not the same as writing a novel. While it might seem difficult to mess up a dictionary, even one with terminology that is as complicated as that used within the space industry – getting it right can be challenging. For those that follow space flight having such a dictionary can be invaluable. While A Dictionary of the Space Age does meet the basic requirements easily it fails somewhat in terms of its comprehensiveness.
When normal folks, even space enthusiasts watch launches and other space-related events (EVAs, dockings, landings and such) there are so many acronyms and jargon thrown about – that it is extremely hard to follow. With A Dictionary of the Space Age on hand, one can simply thumb through and find out exactly what is being said, making it both easier to follow along and making the endeavor being witnessed far more inclusive. That is as long if you are only looking for the most general of terms. The book is far from complete – but given the complex nature of the topic – this might not have been possible.
Crewed, unmanned, military space efforts and satellites – all have key terms addressed within the pages of this book.
The book is published by The Johns Hopkins University Press and was compiled and written by aerospace expert Paul Dickson. One can purchase the book on the secondary market (Amazon.com) for around $12 (new for around $25). The dictionary also has a Kindle edition which is available for $37.76. Dickson’s previous works on space flight is Sputnik: The Shock of the Century.
Weighing in at 288 pages, the book briefly covers the primary terms used within the space community. In short, if you are interested in learning more about space flight – or wish to do so – this is a good book for you.

The potential to fly anywhere in the world in less than an hour took a nosedive today. The test flight of an unmanned, rocket-launched, Mach 20-capable, maneuverable aircraft called the Falcon Hypersonic Technology Vehicle 2 (HTV-2) ended when an anomaly caused loss of signal, and the plane crashed into the Pacific Ocean. Overseen by DARPA, the Defence Advanced Research Projects Agency, this second test flight of the HTV-2 seemingly started out well, as the Minotaur IV launch vehicle successfully inserted the aircraft into the correct trajectory, and the aircraft transitioned to Mach 20 aerodynamic flight. It flew for 9 minutes until it encountered problems and crashed.
Despite the crash, DARPA said the successful transition “represents a critical knowledge and control point in maneuvering atmospheric hypersonic flight.”
“Here’s what we know,” said Air Force Maj. Chris Schulz, DARPA HTV-2 program manager in a statement put out by DARPA. “We know how to boost the aircraft to near space. We know how to insert the aircraft into atmospheric hypersonic flight. We do not yet know how to achieve the desired control during the aerodynamic phase of flight. It’s vexing; I’m confident there is a solution. We have to find it.”
From launch until crash, the flight lasted for about a half an hour.
DARPA’s Falcon is designed to fly anywhere in the world in less than 60 minutes. This capability requires an aircraft that can fly at 13,000 mph, while experiencing temperatures in excess of 3500F.
During the first test flight of HTV-2 on April 23, 2010, telemetry was lost 9 minutes into the flight. A subsequent investigation found that the vehicle encountered unexpected yaw, followed by an uncontrollable roll. The onboard computer then set the vehicle to crash into the ocean.
“In the April 2010 test, we obtained four times the amount of data previously available at these speeds,” said DARPA Director Regina Dugan. “Today more than 20 air, land, sea and space data collection systems were operational. We’ll learn. We’ll try again. That’s what it takes. Filling the gaps in our understanding of hypersonic flight in this demanding regime requires that we be willing to fly.”
The military had hopes of using this type of super-fast plane to reach problem spots around the world quickly.
DARPA said that in the coming weeks, an independent Engineering Review Board will review and analyze the data collected. This data will inform policy, acquisition and operational decisions for future -hypersonic aircraft of this kind. It’s not clear yet whether any development of Falcon HTV-2 will continue.
This is the second major hypersonic setback of 2011. In June, the Boeing X-51 waverider failed when its scramjet encountered a problem on engine startup.

What do these three things have in common: space debris elimination using an air gun, a heat shield made from lunar regolith and lightweight space structures made from ultra-light nanomaterials called “Photonic Muscle?”
They are just three of thirty new concepts that NASA has provided funding to move innovative ideas from formulation to implementation under the NASA Innovative Advanced Concepts, or NIAC, program. Some of the concepts are new ways of dealing with persistent problems; others are completely new ideas, with some in the category that sound so crazy, they just might work.
“These advanced concepts selected for study under NIAC were chosen based on their potential to transform or significantly alter our current approaches to launching future space missions, or building and operating space systems,” said Dr. Bobby Braun, NASA’s Chief Technologist, during a teleconference on Aug. 8, 2011.
NIAC—formerly known as the NASA Institute for Advanced Concepts – is back after being cut in 2007 due to budget constraints. The program began in 1998 and the closure of the think-tank-type of program was cause for dismay by those who believed part of NASA’s mission is to spur research and innovation.
“This was previously an outstanding program at NASA and I am excited to be part of the team that is bringing NIAC back,” said Braun. “This is really part of a small change going on within NASA to take it back to its roots with a focus on advanced technology and innovation.”
Braun added that technology and innovation goes hand in hand with space exploration. “Visionary thinking is important for maintaining our leadership in space,” he said.
Each proposal will receive approximately $100,000 for one year to advance the innovative space technology concept and help NASA meet operational and future mission requirements.
NASA received over 150 different proposals for funding, and the 30 were chosen based on their technical merits and their potential to mature into the transformative capabilities NASA is looking for to improve current space mission operations.
“Some of the proposals are risky, somewhat out-of-the-box ideas and very advanced system concepts that have the potential to revolutionize our missions in the future,” said Joe Parrish, director of the Early Stage Innovation division at NASA’s Office of the Chief Technologist in the Space Technology division. “We recognize that in order to make big gains, sometimes we are going to accept some risks. NIAC is the greatest example of an effort to really look at very far-reaching activities and consciously and willingly take risks and look for big rewards to those risks.”
Some of the winning proposals include advanced propulsion and power systems for space, protecting humans from radiation in space, 3-D printing to construct mini spacecraft, and using flywheels to power a spacesuit.
“The most meritorious proposals allow us to look at many ways to address these problems, any of which would be breakthrough technologies,” said Parrish.
These first “new” NIAC projects were chosen based on being technically substantiated, and they could hopefully mature within about 10 years from mission infusion.
NASA anticipates the funding starting dates to be in early September 2011. “We hope to have NIAC studies on an annual basis, and concepts that do well in their first year could receive up $500,000 for up to two years of additional research,” said Jay Falker, NIAC program executive.
The previous NIAC allowed only non-NASA employees to apply, but the new incarnation permits NASA-based personnel to seek funding for their ideas.
In 2008, the National Research Council conducted a review of NIAC’s effectiveness and made concluded that NASA and the US would be well served by maintaining a mechanism to investigate visionary, far-reaching advanced concepts as part of the agency’s mission. Following an October 2009 hearing by the U.S. House of Representatives Subcommittee on Space and Aeronautics, NASA re-established the NIAC program during fiscal year 2011.
Some of the avant-garde and risky ideas funded under the previous NIAC included the space elevator — a cable to ferry equipment from Earth into orbit — and a solar shield to be unfurled in space to deflect sunlight and counter global warming.
The new concepts announced yesterday include both well-known issues and completely new designs. For example, space debris is a well-identified issue that NASA’s been working on, but using an air gun from a high altitude balloon to shoot pulses into the upper atmosphere to slow down debris is “an approach that’s completely novel to a problem we’ve known about,” Falker said.
Over the next few weeks, we hope to feature several of these concepts in more detail.
