NASA asks for help lassoing an asteroid, gets flooded with replies

NASA is reviewing public proposals for how to handle a hypothetical asteroid bound for impact with Earth.

By Elizabeth Barber,?Contributor / July 29, 2013

NASA Administrator Charles Bolden visits the Jet Propulsion Laboratory in May to inspect a prototype for a spacecraft engine that could power an audacious mission to lasso an asteroid. The agency has received some 400 submissions in response to its Asteroid Grand Challenge, a call for the public's help in defending Earth from asteroids.

NASA has received more than 400 responses to its Asteroid Grand Challenge, issued last month as part of the agency?s ramped-up effort to build its asteroid-wrangling know-how before an Earth-bound asteroid is spotted.

The response comes after NASA announced last month that it has identified about ten thousand Near Earth Objects, that is, asteroids and comets that come within 28 million miles of Earth?s orbit. Just ten percent of those objects are large enough to causes substantial global damage to Earth ? bigger than about 100 feet wide ? and none of them are on an impact trajectory toward our planet.

Still, precedent suggests that we should be prepared: Most research still indicates that it was an errant asteroid that wiped out the non-avian dinosaurs at the end of the Cretaceous period, clearing the world of its million-of-years-in-the-making ecosystem packed with Brobdingnagian animals. That asteroid was about 9 miles wide.

And in the latest harbinger of what a massive asteroid impact could do to the Earth, a meteor exploded above?Chelyabinsk, Russia, in February, injuring about 1,500 people. NASA telescopes had not seen that meteor coming; the agency?s programs are largely focused on monitoring larger objects.

So NASA?s asteroid-mastering timeline is ambitious: NASA plans to have identified an asteroid target for snatching?at the latest in 2016. That asteroid will then be lassoed in 2019 and flung into a trans-lunar orbit in 2021. The agency also hopes to ferry humans to an asteroid as early as 2025, about five years before the projected date that astronauts are to land on Mars.?

The expensive plan???NASA had?asked for $17.7 billion?for?the fiscal year 2014, $105 million of which would go to the Asteroid Initiative???has been the subject of major discord between the House and the Senate. Earlier this month, the?House Committee on Science, Space and Technology passed a NASA authorization bill that would prohibit NASA from pursuing the?Asteroid Redirect Mission?without further clarifying its vague points.??At the same time, the Senate has proposed legislation that would authorize giving NASA $18.1?billion and a full go-ahead on the project.

Meanwhile, though, the asteroid plan is slowly rolling forward, and NASA wants ? needs, perhaps ? the public?s help. Last month, the agency announced a Grand Challenge,?an open call for proposals tackling some of the most vexing questions in astroengineering, for its Asteroid Initiative.

And the response has been enthusiastic. About a month into the challenge, NASA has received some 400 submissions proposing possible asteroid targets and means of nabbing them. The applications are now under review for possible incorporation into the agency?s plans.

Earth has some built-in asteroid deflection techniques of its own, but our atmosphere protects us from asteroids smaller than about 130 feet in diameter, roughly the length of the long-necked dinosaur, Argentinosaurus huinculensis.

Bored again: Does the iPhone lull have you checking out other phones?

With no iPhone refresh expected before the fall, do the dog days of summer have some checking out rival smartphones?

It's easy to succumb to envy in the mobile world. The iPhone 5 is currently the oldest flagship smartphone on the market. Meanwhile Android OEM's such as Samsung, Sony, LG, HTC, and Motorola seem to be releasing new phones every week. Nokia is dropping new Windows Phones fairly regularly, and even BlackBerry has put out three new phones in the last six months. Against all that, it's easy to see why gadget geeks with big phone love could be eyeing - or even trying - alternate phones while they wait. Given some thought the iPhone 5 was boring at launch, is it possible even iPhone owners are bored now?

I feel like I'm growing more and more bored with my iPhone. But my brief affairs with android never turn out well. I always come back. I've had the iPhones 4-5 with android in between. Anyone feeling the same?
Shanicenicolle, iMore forums member

The phone market is increasingly competitive and phones are even picking up elements of fashion. For those who can afford multiple phones, or people in the industry who's jobs require they own and use all the major platforms, it can certainly be nice to be able to change phones and experiences like you do clothes. Sort of like having multiple sets of jewelry, or multiple cars to drive, or hair colors to try, or anything that shakes things up.

I am finding myself bored right now and have jumped ship a few times only to come back very quickly. I again am contemplating test driving the HTC One once it arrives on Verizon. With Sense 5 covering Android it appears to make Android clean and simple but still allow for options if you so desire. If I do, I know I will likely come back, but it's nice to just scratch the itch every now and then.

Looking elsewhere isn't a bad thing. Apple would rather you didn't, of course, but for many it becomes an eye-opening experience. Working for Mobile Nations, I use all the major platforms on a daily basis, and while each one has its own advantages, each one also has its own drawbacks. There are times Android feels liberating to me, others when it frustrates me to tears.

I have the same problem. I'm bored. But I went and got the s4 and came running back to iPhone after two days. I just had too many issues with it overheating. Everything on my sd card got deleted and the camera quality wasn't as good as the iPhone 5 so I was missing that. iphonelvr, iMore forums member

For some, jailbreak seems like a happy middle-ground. There's no additional hardware expense involved, but it opens up new functionality and opportunities for customization, beyond what stock iOS allows. It does

Nope I love my iPhone and I'm mad but glad with myself that I left for a brief stint with Android cause I now truly appreciate the stability, ecosystem and just down right usability of iOS
- swarlos, iMore forums member

Ecosystem is a fine point worth making also, and something we touched upon in our recent Talk Mobile discussions. iOS and the iPhone has the exclusive benefits of Apple's vast media ecosystem. Whatever the song or album, the movie, the book, there's a pretty damn good shout that iTunes will stock it. It's the same story for apps, with an impressive and huge array of apps and games available. Looking through the Windows Phone Store and BlackBerry World in-particular, there are still some glaring gaps that need to be filled.

Nope. Not the least bit bored. I love my iPhone, and all my iOS devices, more than ever. I especially can't wait for iOS 7. It's going to make everything else look worse than it already does.
- jclisenby, iMore forums ambassador

Then, at the other end of the scale, excitement shouldn't be higher than it is right now. OK, we're still in a bit of a hardware drought, but Apple has recently unveiled the biggest new version of iOS since the iPhone first launched. Beyond a complete visual redesign, iOS 7 packs a ton of features both user-facing and under the hood that are set to transform the iOS experience all over again. Those who have tried it ? rightly or wrongly ? are excited, as are the folks who haven't. It's like we're waiting to get a brand new phone, without having to buy one. I know I'm excited, as are a whole lot of other folks in the community.

The bottom line is that no-one, not even Apple, can stop you personally getting bored by a device. It's not always a bad thing because the grass isn't always greener, and sometimes it takes trying something new to make you realize that. But, at the same time we're in the midst of exciting times for iOS. When iOS 7 hits sometime in the fall it will reinvigorate the platform and hopefully excite those who may be finding themselves hit by the boredom fairies.

There's a great discussion brewing in the iMore forums on this very topic, so be sure to jump on over there and have your say!

(AP) ? President Barack Obama's national security team argued Wednesday to keep its sweeping domestic surveillance powers intact, even as it acknowledged some limitations appear inevitable.

Facing unexpectedly harsh opposition from both parties over a once-secret program that sweeps up the phone records of every American, the Obama administration said it wanted to work with lawmakers who seemed intent on putting limits on that authority.

"We are open to re-evaluating this program in ways that can perhaps provide greater confidence and public trust that this is in fact a program that achieves both privacy protections and national security," Robert Litt, counsel to the Office of the Director of National Intelligence, told skeptical members of the Senate Judiciary Committee.

The hearing came one week after a surprisingly close vote in the House that would have killed the phone surveillance program. It barely survived, but lawmakers promised that change was coming.

This newest privacy-vs.- security debate was touched off when former government contract systems analyst Edward Snowden leaked classified documents exposing National Security Agency programs that store years of phone records on every American. That revelation prompted the most significant reconsideration yet of the vast surveillance powers Congress granted the president after 9/11.

The administration intended to keep the telephone program a secret forever and, for more than a decade, few in Congress showed any interest in reining in the surveillance. Snowden's leaks abruptly changed the calculus on Capitol Hill.

"We have a lot of good information out there that helps the American public understand these programs, but it all came out late," Sen. Sheldon Whitehouse, D-R.I., said in a rebuke of government secrecy. "It all came out in response to a leaker. There was no organized plan for how we rationally declassify this so that the American people can participate in the debate."

The telephone program is authorized under a provision of the USA Patriot Act, which Congress hurriedly passed after 9/11.

The Obama administration says phone records are the only records being collecting in bulk under that law, but it has left open the ability to create similar databases of people's credit card transactions, hotel records and Internet searches.

Several Democrats promised bills that would provide tighter controls or more transparency. Proposals include eliminating the FBI's ability to seize data without a court order, changing the way judges are appointed to the surveillance court, and appointing an attorney to argue against the government in secret proceedings before that court. Another would force the government to reveal how many Americans have had their information swept up in surveillance.

On Wednesday, the national security establishment sought to reassure Congress that its surveillance powers were rigorously monitored and narrowly crafted while simultaneously leaving open the possibility of some new limitations.

To that end, the administration declassified documents about the telephone program. But the documents revealed no legal analysis that underpinned the widespread surveillance. And the redacted documents show only in broad strokes how NSA officials use the data.

For the first time, however, the government acknowledged publicly that using what it calls "hop analysis," it can analyze the phone calls of millions of Americans in the hunt for just one suspected terrorist. That's because NSA analysts can look at not just a suspect's phone records, but also the records of everyone he calls, everyone who calls those people and everyone who calls those people.

If the average person calls 40 unique people, three-hop analysis could allow the government to mine the records of 2.5 million Americans when investigating one suspected terrorist. The Obama administration has

"What's being described as a very narrow program is really a very broad program," said Sen. Richard Durbin of Illinois, the No. 2 Democrat in the Senate.

John Inglis, the NSA's deputy director, conceded the point but said, in practice, such broad analysis was rare.

"We have to compare the theory to the practice," he said.

Last week's House vote of 217-205 defeating an attempt to dismantle the program was significant not only because of the narrowness of the victory for the Obama administration, but also because it created unusual political coalitions. Libertarian-leaning conservatives and liberal Democrats pressed for change against the Republican establishment and Congress' pro-security wing.

Backing the NSA program were 134 Republicans and 83 Democrats, including House Speaker John Boehner, R-Ohio, who typically does not vote, and Democratic leader Nancy Pelosi. Rejecting the administration's last-minute pleas to spare the surveillance operation were 94 Republicans and 111 Democrats.

AMERICAN OIL 'THREAT' Saudi Investor Warns of US Energy Boom Effects

America?s energy boom is putting a scare into Saudi Arabia.

According to the Wall Street Journal, Saudi billionaire Prince Alwaleed bin Talal warned in a letter to Saudi Oil Minister Ali al-Naimi and others that the U.S. boom of shale oil and gas will reduce its thirst for Saudi crude oil.

?With all due respect to your Highness? viewpoint about shale gas and that it poses no danger on Saudi economy at ?the present time,?? read a translation of the letter, dated May 13 but only recently tweeted on a Twitter page previously used by Alwaleed. ?I was hoping that your Highness would also shed light and focus on the danger of this matter in the ?not-so-distant future,? especially that America and some Asian countries made big discoveries in shale gas extraction which will affect the oil industry around the world in general and Saudi Arabia in particular??

The prince, who is worth an estimated $20 billion and founded Kingdom Holding, warned that the nation's near total reliance on oil revenues could leave it vulnerable when demand drops due to other nations' domestic production.

"Our country is facing a threat with the continuation of its near-complete reliance on oil, especially as 92 percent of the budget for this year depends on oil," wrote Alwaleed, who owns seven percent of the voting shares in News Corp, the former parent company of Fox News. "It is necessary to diversify sources of revenue, establish a clear vision for that and start implementing it immediately."

News of the letter comes after a newly published report from OPEC which showed that the group's export revenue hit a record high of $1.26 trillion in 2012. Forecasts have questioned whether that earning level can be sustained amid competition from fracking in countries that import OPEC oil and gas.

?The Saudis have a huge competitive advantage, in that the cost for them to produce oil is very low, just a few dollars per barrel. So, Saudi Arabia is not going to find itself unable to sell its crude oil,? Jonathan Lesser, an economist who specializes in the energy industry, told FoxNews.com. ?What it is likely to find is that its ability to control prices on the world oil market will decrease over time; slowly, but decrease nevertheless.?

Saudi Arabia is the world?s largest exporter of crude but is now extracting less than capacity because consumers are importing less. Al-Naimi has played down the significance of shale oil production despite other OPEC member nations saying they have seen a sharp drop.

Oil revenue in Algeria fell by 6 percent last year, and in Iran, where exports have been curtailed by western sanctions, exports fell 8 percent.

Data from OPEC suggests other member nations could feel the sting of revenue loss as demand for crude will fall to about 30 million barrels a day in 2014. The average price has already dropped by 4 percent this year.

Production of oil in the U.S. has grown to record highs in 2012 and is expected to continue to rise. Daily crude production averaged 6.4 million barrels per day, a 15-year high. Stateside production is catching up to import needs, as 7.5 million barrels are being made while the U.S. produces 10.6 million barrels a day.

Lesser said Alwaleed is wise to recognize that the market dynamics are changing.

?A more basic concern is that any economy that relies heavily on a single commodity ? be it oil in Saudi Arabia or copper in Chile ? faces greater potential disruption when the market fundamentals for that commodity change,? Lesser said.??So, the Prince is correct, especially when he notes that Saudi Arabia needs to diversify its economy.?
