Four videos for Asteroid Day 2017 a week late

I usually build my entries around videos, so it was unusual when I didn't do that for Asteroid Day and National Meteor Watch Day share June 30th.  I had one that I was going to include, but forgot about it I wrote about National Meteor Watch Day instead.  Here it is, Astrophysicist Warns Devastating Asteroid Strike ‘Just A Matter Of Time’ from GeoBeats News.

An astrophysicist from Queen's University Belfast is warning that Earth is incredibly vulnerable to an asteroid strike.

Cheerful, isn't it?  Seriously, it's why I started Apophis Day in the first place and why Asteroid Day exists as well.  Speaking of which, Newsy reported Why International Asteroid Day matters.

Today, we look back on the progress we've made tracking risky asteroids and forward to the ones we still haven't found yet.

Follow over the jump for two videos, one from NASA explaining how Near-Earth Objects are found and another from Newsy about what NASA plans to do about at least one of them.

For Asteroid Day, NASA/JPL posted NASA Planetary Defense: The Asteroid Hunters.

Two unique ground telescope operations, at the Catalina Sky Survey in Mt. Lemmon, Arizona, and the Panoramic Survey Telescope and Rapid Response System, or PanSTARRS, located at Haleakala, Hawaii, are responsible for about 90 percent of all near-Earth object discoveries.

Just a couple days ago, Newsy followed up with NASA gets ready to defend Earth from asteroids.

The Double Asteroid Redirection Test hopes to move near-Earth threats away from our planet.

I'm encouraged; people are actually doing something useful about the problem.
