A THREE MILE wide asteroid is set to graze past Earth this Friday

Posted by in category: asteroid/comet impacts

A massive asteroid estimated to be 2.7 miles wide is set to make a ‘relatively close encounter’ with Earth on 1 September.

Dubbed ‘Florence,’ the huge space rock will pass just 4.4 million miles from our planet on Friday – or, about 18 times the distance between Earth and the moon.

A plane-size asteroid buzzes by Earth undetected

We Will Rock You

Today is World Asteroid Day… https://bcgallie.wixsite.com/asteroidday


Asteroid Day is a global awareness movement to protect Earth against asteroid impacts. The original inspiration for this campaign came from Grigorij Richters’ asteroid impact disaster film 51 Degrees North — all profits from which he has now dedicated to the cause of Asteroid Day world-wide. Dr. Brian May is a key supporter and delivered a slight update of the original mix, specifically for the Asteroid Day launch. Learn more about Asteroid Day, here: http://www.asteroidday.org

1,000-Foot-Wide Asteroids That Could Hit Earth Discovered

Posted by in category: asteroid/comet impacts

Scientists have discovered a new branch of the Taurids meteor stream that could pose a major risk to Earth, with asteroids up to 1,000 feet wide flying past us every few years. The Taurids meteor shower peaks every October and November, producing a relatively small display of shooting stars as the planet.

Cassini images suggest asteroid strike forced Enceladus poles to shift

Posted by in categories: asteroid/comet impacts, existential risks

NASA has announced that asteroid strikes may have tipped over Saturn’s icy, ocean-bearing moon Enceladus. Researchers came to the conclusion after analysing the latest images and data from Cassini.

Researchers say they have enough evidence to suggest the moon’s spin axis – the line through the north and south poles – reoriented from its original position due to a collision with a smaller body, most likely an asteroid. The shift from its original axis is by 55 degrees, more than halfway rolling completely onto its side.

World Asteroid Day Hackathon

Posted by in categories: asteroid/comet impacts, cybercrime/malcode, education, existential risks, media & arts

“A hackathon (also known as a hack day, hackfest or codefest) is a design sprint-like event in which computer programmers and others involved in software development, including graphic designers, interface designers, project managers, and others, often including subject-matter-experts, collaborate intensively on software projects. Occasionally, there is a hardware component as well. Hackathons typically last between a day and a week. Some hackathons are intended simply for educational or social purposes, although in many cases the goal is to create usable software.” https://en.wikipedia.org/wiki/Hackathon

In February 2014, Dr. Brian May, astrophysicist and famed guitarist for the rock band QUEEN, began working with Grigorij Richters, the director of a new film titled 51 Degrees North, a fictional story of an asteroid impact on London and the resulting human condition. May composed the music for the film and suggested that Richters preview it at Starmus, an event organized by Dr. Garik Israelian and attended by esteemed astrophysicists, scientists and artists, including Dr. Stephen Hawking, Richard Dawkins and Rick Wakeman. The result was the beginning of discussions that would lead to the launch of Asteroid Day in 2015. See : https://asteroidday.org/

Rejuvenation would be too expensive to create

Posted by in categories: asteroid/comet impacts, economics, existential risks, finance, life extension

Creating rejuvenation will probably be quite expensive, but that’s no reason to give up on it. We can pull it off.


The first thing to realise is that, when you wonder how much something will cost, you’re actually wondering how many resources and how many people doing how much work it will take to do that something. That’s all that really matters. The problem is that we have a sucky economic system such that even if we do have more than enough people and resources to do the job, the monetary cost of it could be so high that you can’t get the job done without creating financial problems left and right. This should be a hint that the problem, if it exists, lies in our crappy economic system, not in rejuvenation itself or whatever other thing we may create.

Apart from the obvious fact that other hysterically expensive endeavours (such as space missions) are pulled off despite their costs, we must take into account that desperate circumstances call for desperate measures. We don’t need to tear apart our economic system and replace it with another before we create rejuvenation, and neither would we if faced with another health crisis (such as a pandemic) or a planetary crisis, but we need to get the job done despite its costs and the consequences they may have. We can’t give up on rejuvenation on the grounds that it may be too expensive to create, just like we wouldn’t in the case of an existential risk. Can you imagine that? There’s a huge asteroid on a collision course with Earth, and our only hope is a spectacularly expensive space mission to destroy it before it’s too late. Just who in their right mind would step up and say: ‘Nah, too expensive. Let’s not do it.

DESTAR phased array laser systems for defending against asteroids and for space exploration

Posted by in categories: asteroid/comet impacts, space travel

A laser phased array directed energy system has been designed and simulated. Lubin and Hughes calculated the requirements and possibilities for DE-STAR systems of several sizes, ranging from a desktop device to one measuring 10 kilometers, or six miles, in diameter. Larger systems were also considered. The larger the system, the greater its capabilities.

For instance, DE-STAR 2 – at 100 meters in diameter, about the size of the International Space Station – “could start nudging comets or asteroids out of their orbits,” Hughes said. But DE-STAR 4 – at 10 kilometers in diameter, about 100 times the size of the ISS – could deliver 1.4 megatons of energy per day to its target, said Lubin, obliterating an asteroid 500 meters across in one year.
