Interview to Celebrate the 50th Anniversary of the Apollo 11 Landing on the Moon

On July 20, 2019, our local ABC news station (KVUE) came by to interview me for the 50th Anniversary of the Apollo 11 landing on the moon. I really enjoyed discussing meteorites and sharing some of my collection with the audience. I thought Hank Cavagnaro did a great job of properly presenting meteorites for the audience.

Delta AquariidsJuly 12 to August 23 20Aquarius near the star Delta AquariiSteady stream of meteors over several days. Likely
associated with Comet 96P/Machholz.
Alpha Capricornids (no link)July 15 to August 255CapricornYellow slow fireballs. Associated with Comet 169P/NEAT.
PerseidsJuly 23 to August 2075PerseusMany bright fast meteors with trains. Associated with

Note, some resources refer to the Northern Taurids as
being associated with the asteroid 2004 TG10, that also
shares the same parent body as Comet 2P/Encke. The
Beta Taurid meteor stream is the suspected source of the
massive and devastating June 1908 Tunguska airburst.
LeonidsNovember 15 to 2030-300LeoFast bright meteors with fine trains. Associated with

Anthony Bourdain’s Meteorite Chef Knife Sells for $231,250

I remember hearing the sad news in June of 2018 that Anthony Bourdain, famous chef, book author, TV personality and overall down-to-earth super cool dude, had taken his own life. Crystal (my wife) and I happened to be in Colmar, France where he died shortly after the announcement as we were attending the Ensisheim Meteorite show and though we did not visit the site, we did feel a sense of loss at the passing of one of the few real people in reality TV. Like many fans, we really enjoyed watching Anthony’s adventures on TV and I remembered watching in fascination the show (see below) where certified blade-master, Bob Kramer, made Tony’s now famous meteorite chef knife. So, when I saw a press release in early October 2019 that this specific knife would go up for auction, I was really excited. iGavel Auctions had predicted it would sell for anywhere between $4,000 and $6,000, and I figured I had a chance. Once bidding opened, the price quickly rose to around $22,000, and my dreams fell equally fast. The bids stayed at that level for most of October, The bidding got stuck at around $22K and I guessed it might go up as high as $30,000.

Out of the more than 200 listings in the auction, Bourdain’s chef knife netted the highest bid of $185,000. After adding in the 25% buyer’s premium of $46,250, the total price came to a whopping $231,250!

Click on the image and then use magnify. Then, by scrolling sideways the user gets an excellent perspective of the relative size of the 88 known objects (from 2007) in our solar system larger than 322 kn (200 miles) in diameter.

Five (5) Moons of the Dwarf Planet Pluto

Image shows a sliver of Pluto’s largest moon, Charon, and all four of Pluto’s small moons, as resolved by New Horizons spacecraft. Charon has a diameter of 751 miles (1,212 kilometers). Nix & Hydra have comparable sizes, approximately 25 miles (40 kilometers) across in their longest dimension above. Kerberos and Styx are much smaller and have comparable sizes, roughly 6-7 miles (10-12 kilometers) across in their longest dimension. All four small moons have highly elongated shapes, a characteristic thought to be typical of small bodies in the Kuiper Belt.
