NASA will attempt to knock an asteroid out of orbit for the first time in 2022

  • If an asteroid were to head towards Earth in the foreseeable future, we would be quite defenceless.
  • To change that, NASA has approved a mission to throw a “small” asteroid off course in October 2022.
  • The aim of the project is to establish whether we can protect our planet from a future asteroid impact.

If an asteroid were to head towards Earth, we would be quite defenceless as we have not successfully developed a method that could reduce the impact of — or entirely avert — a devastating collision.

However, that may be about to change. NASA has approved a project called the Double Asteroid Redirection Test (DART), the aim of which is to throw a “small” asteroid off course in October 2022.

Time to Say Goodbye to Coffee?

Saying farewell to coffee isn’t that easy. According to research about three-fifths of all our beloved coffee species are going to go extinct. This is a phenomenal amount of coffee that we risk losing.

Here’s something to think about as you sip that morning mochaccino:?Deforestation, climate change and the proliferation of pests and fungal pathogens are putting most of the world’s wild coffee species at risk of extinction.

At least 60 percent of wild coffee species are considered “threatened,” according to a study published this week in Science Advances. And fewer than half of all the wild species are safeguarded in so-called germplasm collections—banks for seed and living plants kept in protected areas as backups.

Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There

Scott Aaronson — The Winding Road to Quantum Supremacy

This was the first part in an interview series with Scott Aaronson — this one is on quantum computing — other segments are on Existential Risk, consciousness (including Scott’s thoughts on IIT) and thoughts on whether the universe is discrete or continuous.

Ok, the new version of my global risk prevention map is up (pdf link is in comments) and now it is accompanied by recently the published article “Approaches to the Prevention of Global Catastrophic Risks.”

Abstract: Many global catastrophic and existential risks (X-risks) threaten the existence of humankind. There are also many ideas for their prevention, but the meta-problem is that these ideas are not structured. This lack of structure means it is not easy to choose the right plan(s) or to implement them in the correct order. I suggest using a “Plan A, Plan B” model, which has shown its effectiveness in planning actions in unpredictable environments. In this approach, Plan B is a backup option, implemented if Plan A fails. In the case of global risks, Plan A is intended to prevent a catastrophe and Plan B to survive it, if it is not avoided. Each plan has similar stages: analysis, planning, funding, low-level realization and high-level realization. Two variables—plans and stages—provide an effective basis for classification of all possible X-risks prevention methods in the form of a two-dimensional map, allowing the choice of optimal paths for human survival. I have created a framework for estimating the utility of various prevention methods based on their probability of success, the chances that they will be realized in time, their opportunity cost, and their risk. I also distinguish between top-down and bottom-up approaches.

How The 1% Will Live After The End Of The World | VICE on HBO (Bonus)

Throughout human history, doomsayers — people predicting the end of the world — have lived largely on the fringes of society. Today, a doomsday industry is booming thanks to TV shows, movies, hyper-partisan politics and the news media. With the country’s collective anxiety on the rise, even the nation’s wealthiest people are jumping on board, spending millions of dollars on survival readiness in preparation for unknown calamities. We sent Thomas Morton to see how people across the country are planning to weather the coming storm.

Astronaut says a neglected telescope is NASA’s best chance of defending Earth from ‘city killer’ asteroids — ‘for God’s sake, fund it’

Killer asteroids might be a bigger threat than you think.

  • Small asteroids can strike Earth with the force of many nuclear weapons and destroy entire cities.
  • A small fraction of such asteroids is estimated to have been found, but NASA is supposed to find 90% of them by 2020.
  • Retired astronaut Rusty Schweickart says a relatively inexpensive space telescope, called the Near-Earth Object Camera, could find these space rocks — and quickly.
  • NASA has denied full funding to NEOCam multiple times because the agency’s mission selection process is weighted against the telescope.
  • NEOCam’s supporters say the telescope needs just $40 million more in NASA’s budget to launch into space.
  • It’s up to President Trump and Congress to raise NASA’s budget enough to support the mission.

A former NASA astronaut says the agency he used to work for has a duty to protect civilians from killer asteroids, but that it isn’t meeting that obligation.

The threat of asteroid strikes might seem as abstract as outer space itself. But the risk, while infrequent, is real — and potentially more deadly than the threat posed by some of the most powerful nuclear weapons ever detonated.

Apollo Astronaut claims Aliens PREVENTED a NUCLEAR WAR on Earth to ensure our existence

The write up provides few sources but the phone interview with Mitchell on Fox News is good…

The Sixth Man to walk on the Moon – Edgar Mitchell made fainting claims about alien life when he stated that the existence of the alien visitors is kept a secret from the public, not due to fear of widespread disbelief, rather, a fear that the monetized interests of big business could go into a state of irrelevance if we were given a chance to harbor the technology.

According to reports, Edgar Mitchell, the sixth man to set foot on the surface of the moon disclosed details about alien life and their presence on Earth which much considered ludicrous.

However, these claims are not coming from someone without any solid backgrounds. Edgar Mitchell has a very solid history behind him. The Former NASA astronaut graduated from the Carnegie Institute of Technology in 1952, with a degree in Industrial Management. He continued his studies while serving in the US Navy where he managed to combine his military career with improved education, studying another bachelors degree in Aeronautical Engineering within the naval postgraduate school in 1961.
