SPOOKY – THE GREAT PUMPKIN HALLOWEEN ASTEROID TO MAKE A CLOSE ENCOUNTER

With a diameter of between 984 to 1,542 feet, Asteroid 2015 TB145 will be too faint to be seen with the naked eye when it passes close to earth at a distance of 310,000 miles with a velocity of 78,000 MPH on October 31, 2015.

If you don't have your own telescope, two possible venues for viewing the event are:

1) The Virtutal Telescope Project webcast October 30 at 8 PM EDT (0000 GMT Oct 31.) on: http://www.virtualtelescope.eu/2015/10/20/potentially-hazardous-asteroid-2015-tb145-very-close-encounter-live-event-31-oct-2015/

2) Slooh Astronomy Network coverage October 31 at 1 PM EDT (1700 GMT Oct. 31)
on: http://live.slooh.com/?utm_campaign=space&utm_medium=textlink&utm_source=launch

The asteroid will be radar tracked via a transmitter in Goldstone California and two receivers – one at Green Bank, West Virginia and one at Arecibo, PR.

Based on TB145’s unusual trajectory there is some speculation that this asteroid may actually be a comet.

3 Reasons to Celebrate Earth Day

Dear (newsletter recipient),

Today is Earth Day, and I want to drop you a line to thank you for your steadfast support of the B612 Foundation’s important work to increase global awareness on the issue of planetary defense and the need to accelerate the discovery of asteroids.

Just yesterday, a 15m rock named Asteroid 2015 HD1 passed Earth, only 0.2 lunar distances away (45,600 miles). HD1 was only discovered by the Tucson-based Mt. Lemmon Survey three days ago on April 18. This reinforces our need to accelerate the discovery of asteroids.

Fortunately, since the launch of the B612 Foundation and the Sentinel Mission, there has been a big shift in the global conversation around asteroid detection. And today, on Earth Day, we have much to celebrate! We couldn’t have done it without your support. Some of our major accomplishments in the last year include:

* Being a founding partner in the global movement for asteroid awareness that will culminate in Asteroid Day on June 30, 2015. Many B612/Sentinel Mission supporters are signers of the 100X Asteroid Declaration and are planning Asteroid Day events.

* Release of our Asteroid Impacts video on Earth Day 2014, using data from The Comprehensive Nuclear Test Ban Organization, shook people’s assumption of how often the Earth is hit by asteroids. This network has never actually detected an atmospheric nuclear explosion, but it instead has detected many multi-kiloton asteroid explosions! The video shows the locations and sizes of asteroid impacts on Earth since 2000, showing that a significant-sized asteroid impacts Earth’s atmosphere on average twice a year! The video has had over 2.5 million views and has been translated into Chinese and Spanish.

* Presenting important new research to the planetary defense community that confirms the Sentinel Space Telescope, a project of the B612 Foundation, in a Venus-like orbit is twice as effective at finding potentially Earth-impacting asteroids than a telescope tied to Earth. This research was unveiled last week at the 4th annual Planetary Defense Conference.

It’s because of your continued support that we’re able to move forward with these important contributions to planetary defense. I hope you’ll consider making a gift today to continue the advancement of this important field. Thank you.

~ (signed Ed Lu co founder of B612)

In an effort to raise public awareness of the possibility of a fatal asteroid event, Asteroid Day has been planned and will take place June 30, 2015.

Sentinel Mission Director Harold Reitsema and Mission Scientist Dr. Marc Buie will team up to present their current view of the Sentinel mission parameters to the 46th Lunar & Planetary Science Conference this March in Houston TX. Dr. Buie has completed a simulation model which will explain why the proposed neo-Venusian orbit is twice as effective as the 1 million mile L1/L2 earth orbits.

This February 2013 article from Universe Today discusses the ESA/US proposal to send two spacecraft (a US collider - DART and an ESA mother ship - AIM) to Didymos to see if it's orbit can be modified and to carry out scientific data collection.

The joint project is called AIDA - Asteroid Impact and Deflection Assessment.

Just hit upon a project called ATLAS: Asteroid Terrestrial-Implact Last Alert System. It is a ground based system of 8 small telescopic cameras with up to 100 megapixel resolution. It should provide up to seven days warning of a 45 meter city killer rock. Read about it here:

Very strange. I tested the link after posting it and it worked. I see it isn't working now - possibly because 'earth' was misspelled in the link.

Here is a link that shows the same video but does not have the accompanying text that the original link had:
http://www.space.com/25589-asteroid-impacts-on-earth-more-powerful-than-nuclear-bomb-video.html

Sorry for the typo and confusion.
