NASA inadequate for Planetary Defense

From: http://missoulanews.bigskypress.com/IndyBlog/archives/2011/11/14/extra-extra-in-other-news-online


After Charlie Bolden, the administrator of NASA, declared that deflecting a near-earth object (NEO), such as an asteroid or a comet, will be “what keeps the dinosaurs—we are the dinosaurs, by the way—from becoming extinct a second time,” he admitted that the space agency couldn’t afford to tackle that task, even if it wanted to. He explained that the annual federal allocation for “planetary defense” is $5.8 million, which represents a mere 0.03 percent of NASA’s budget and is barely adequate merely to locate NEOs and track their orbits.

Quarter-mile-wide asteroid coming close to Earth

CAPE CANAVERAL, Fla. (AP) — An asteroid bigger than anaircraft carrier will dart between the Earth and moon on Tuesday — the closest encounter by such a huge rock in 35 years.
But scientists say not to worry. It won't hit.
"We're extremely confident, 100 percent confident, that this is not a threat," said the manager of NASA's Near Earth Object Program, Don Yeomans. "But it is an opportunity."
The asteroid named 2005 YU55 is being watched by ground antennas as it approaches from the direction of the sun. The last time it came within so-called shouting distance was 200 years ago.
Closest approach will occur at 6:28 p.m. EDT Tuesday when the asteroid passes within 202,000 miles of Earth. That's closer than the roughly 240,000 miles between the Earth and the moon.
The moon will be just under 150,000 miles from the asteroid at the time of closest approach.
Both the Earth and moon are safe — "this time," said Jay Melosh, professor of Earth and atmospheric sciences at Purdue University.
If 2005 YU55 were to plow into the home planet, it would blast out a crater four miles across and 1,700 feet deep, according to Melosh's calculations. Think a magnitude-7 earthquake and 70-foot-high tsunami waves.
Scientists have been tracking the slowly spinning, spherical, dark-colored object since its discovery in 2005, and are positive it won't do any damage.
"We know the orbit of this object very well," Yeomans said.
The asteroid stretches a quarter-mile across. Smaller objects come close all the time, Yeomans noted, but nothing this big will have ventured so close since 1976. And nothing this large will again until 2028.
Radar observations from California and Puerto Rico will help scientists ascertain whether theasteroid is pockmarked with craters and holds any water-bearing minerals or even frozen water.
Amateur astronomers would need a 6-inch-or-bigger telescope and know exactly where to look to spot it.
Astronomers consider 2005 YU55 a C-type asteroid — one containing carbon-based materials. "It's not just a whirling rock like most of them," Yeomans said.
Such objects are believed to have brought carbon-based materials and water to the early Earth, planting the seeds for life. The discovery of water-bearing minerals or ice would support that theory, Yeomans said.
This is the type of asteroid that NASA would want to aim for, with astronauts, Yeomans said, especially if frozen water is found. Such asteroids could serve as watering holes and fueling stations for future explorers, he said.
An asteroid is actually on NASA's short list for destinations.
President Barack Obama wants astronauts headed to an asteroid and then Mars in the coming decades. That's why the 30-year space shuttle program ceased this summer — so NASA could have enough money to get cracking on these new destinations.
As for an actual strike by an asteroid this size, that's estimated to occur once every 100,000 years or so.
An asteroid named Apophis — estimated to be 885 feet across — will venture extremely close on April 13, 2029 — but will not strike. It has a remote chance of hitting Earth when it comes around again on April 13, 2036.
Scientists said information gleaned from 2005 YU55, as well as other asteroids, will prove useful if and when it becomes necessary to deflect an incoming Armageddon-style rock. (From Philstar.com)

In Orbit
Space Solar Power Seen Profitable By 2040

Printed headline: Closing The Case
Conventional wisdom typically holds that harvesting “free” energy from the Sun with giant collectors in space does not make financial sense, at least until Earth’s finite supplies of oil, coal and natural gas become so scarce that there’s no other choice. The conventionally wise usually suggest that it will make more economic sense to rely on wind power and ground-based solar cells for “green” renewable energy. But now a panel of the International Academy of Astronautics (IAA), an elite organization of scientists, engineers and other experts who collectively examine some of the big issues of space exploration, has concluded that space solar power (SSP) could start paying for itself in as little as a decade.
John Mankins, a leading SSP visionary, co-chaired the IAA panel with Nobuyuki Kaya of Japan’s Kobe University, where a lot of the technical ground for SSP already is being broken. They presented their findings at the National Press Club in Washington on Nov. 14, after unveiling them at the International Astronautical Congress in Cape Town, South Africa, last month. Examining various SSP approaches and four scenarios for the way global energy needs will influence the world economy, the IAA panel concluded that “premium niche markets” could support SSP profitably in the relative near term, particularly if some new approaches to assembling the big space-based collectors are followed. Technical hurdles that remain to be surmounted include thermal control, either with better spaceradiators or higher-temperature electronics. But the SSP idea is more attractive now that at any time since it first was conceived in the late 1960s.

“There has been general consensus in every study, both here and abroad, that space solar power is technically feasible, that there are no show-stoppers,” says Mark Hopkins, CEO of the National Space Society, which sponsored a panel discussion of the IAA report at the press club. “But this is the first major study which has come out and said there’s a good chance it can be economically viable.”
Mankins says the study examined three “promising” SSP concepts for positioning in geostationary orbit—a stabilized platform using solar arrays like those on the International Space Station to generate electricity converted to microwaves for transmission to large rectifying antennas (rectennas) on Earth; a modular approach linking solar arrays and lasers beaming down power in near-visible wavelengths, and a modular approach concentrating solar energy with large mirrors before converting it to microwaves.
The stabilized platform was studied in depth in 1979, Mankins says, and is no longer attractive because it is limited to about 100 kw without being “fundamentally rearchitectured.” The laser approach runs into efficiency issues in competition with other power-generation systems above 100 mw, according to the IAA, while the modular “sandwich” microwave architecture is the most promising because it is scalable.
“One of the things which appears very promising now is the idea that through these hypermodular architectures, that you can build fairly tractably, with tens of millions of dollars, a prototype of a module,” Mankins says. “And for a bit more money you can make a bunch of copies of those modules.”
The microwave approach will require more work on thermal control, Mankins said, and any large structure will require advances in on-orbit assembly, in-space propulsion and, ultimately, launch vehicles. But at least initially a 10-mw system costing $10 billion, of the type already considered by the Pentagon for supplying power to forward-deployed bases and disaster areas, probably could be launched with existing or planned vehicles like the Delta IV Heavy and Falcon 9 Heavy, respectively.
The IAA panel concluded that for the rest of the century, growing demand for electricity will call for many new sources of energy. Wind and terrestrial solar power will help, but unlike SSP are subject to local weather conditions. Space-generated power, by contrast, can be beamed to areas where weather is temporarily stilling windmills and blocking sunlight, Mankins says.
The IAA report does not assume that SSP will totally replace other sources of electricity, but finds it can gradually assume a larger role as the global population grows from 7 billion to twice that by century’s end. U.S. military strategists have long seen SSP as an alternative to the “energy wars” they fear as fossil fuel supplies dwindle, while development of SSP technology will place the nation or nations that control it in a strong position to shape geopolitics. Another benefit may come with the jobs generated by large-scale SSP production.
“If you think about the skill set that is necessary to build a system like Orbcomm or GPS, it’s that same kind of skill set, but a lot of them,” Mankins says. “At full scale by mid-century, space solarpower is like the automotive industry, meaning you have a very large and high-tech workforce and a set of infrastructure with factories building pieces of solar power satellites. The reasonable number [for SSP generating 100-200 gw] works out to millions of jobs.”

Near Earth Object Media/Risk Communications Experts Gather

From: http://www.newswise.com/articles/near-earth-object-media-risk-communications-experts-gather

Newswise — An expert group of scientists, reporters, and risk management specialists have taken part in a Near Earth Object Media/Risk Communications workshop.
Output from these professionals is helping to draft a report for the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) Scientific and Technical Subcommittee, the Working Group dedicated to organizing an approach that counters the potential threat posed by Near Earth Objects, or NEOs.
Specifically, that UN Working Group in its deliberations is appraising establishment of an Information, Analysis and Warning Network (IAWN).
The team of workshop participants included leading journalists and writers, hazard communication authorities, artists and NEO researchers. The invite-only setting for the meeting – held November 14-15 – was the University of Colorado, Boulder’s Laboratory for Atmospheric and Space Physics (LASP).
This NEO Media/Risk Communications Workshop was convened by Secure World Foundation and the Association of Space Explorers.
Reach, teach, and motivate
Among issues discussed during the two-day workshop:
-- What are effective tools to empower audiences with a tangible outreach and education plan, one that fosters accurate and timely information about the possible effects of a potentially hazardous NEO and what actionable steps can they take?
-- How best to inform the public regarding NEOs and any Earth-threatening object in a way to avoid misinformation?
-- What steps can be taken to develop an outreach and education plan, one that offers accurate and timely information about the possible effects of a potentially hazardous NEO?
Counteract consequences
Secure World Foundation has a long-standing interest for maintaining a vigilant eye on NEOs, as well as the establishment of a Planetary Defense strategy.
The consequences stemming from a NEO plowing into the Earth depends on its size and trajectory. Damage could range from destruction of an area the size of a city, to creation of tsunamis, to far greater after-effects.
“Establishment of a Planetary Defense strategy includes a number of components, from finding potentially hazardous objects, predicting their future locations, and providing warning about future impacts with the Earth,” said Dr. Ray Williamson, Executive Director of Secure World Foundation.
Furthermore, a Planetary Defense strategy also includes missions to deflect impacting asteroids by changing their orbit, as well as disaster preparedness management and, in the event of a NEO strike, shaping a mitigation and recovery plan to counteract consequences.
Resources and contacts
The need for an IAWN had been identified in Asteroid Threats: A Call for a Global Response, a report prepared by an expert panel convened by the Association of Space Explorers (ASE) to assist the work of the UN COPUOS Action Team on Near-Earth Objects (AT-14), which was established in 2001.
That report is available here:

When looking beyond near-Earth space and LEO, several missions and target destinations are viable. These include Earth's closest solar system neighbors: the Earth-Moon or Sun-Earth Lagrange points and cis-lunar space, NEAs, the Moon, the moons of Mars, and Mars. Each destination provides unique exploration and operational opportunities. Lunar circumnavigation and flights to Earth-Moon or Earth- Sun Lagrange points hold near-term promise as compelling test locations for the SLS, Orion MPCV, and other key emerging systems. Lagrange points are gravitationally stable regions created by the interaction of the gravity fields of any two large masses; an object placed at a Lagrange point will tend to stay in place for a long time. The Earth-Moon L1 and L2 Lagrange points could therefore be excellent "gateways" for a multitude of exciting exploration missions. The NEAs provide the opportunity to send humans beyond the solar orbit of Earth while holding compelling science and planetary defense knowledge-building potential. In addition to possible scientific prospects, missions to NEAs would afford astronauts the experience applicable to deeper-space missions that would eventually contribute to establishing a permanent human presence beyond Earth. There are a few asteroids which could be visited by the SLS and Orion MPCV in the timeframe under consideration. Additional NEA survey data will be required to identify and refine the catalog of potential targets.
