Steve Kates

Steve Kates, known as Dr. Sky, tells John Catsimatidis about a two-pound meteorite found in the Sahara in 2022 that is thought to be a piece of Mars, one of about 435 such meteorites. He says new research suggests that comets may not have seeded Earth with life after all, and recalls the Silver Bird, a space plane Germany planned during World War II.

Key takeaways

  • Kates said the Sahara meteorite contains trapped gases and other components.
  • He said new research suggests amino acids from comets would have burned up from reentry friction.
  • He said comets may have seeded life on Mars, which has less of an appreciable atmosphere.
  • Kates said the main theory is that a collision stripped Mars of its atmosphere and surface water.
  • Kates said the Silver Bird was meant to drop a bomb on the New York City area.

Speaker 1 Sunday morning. What’s going on up in the skies? With us today is Steve Cates, otherwise known as Dr. Sky. And Steve, give us an update. What’s going on out there?

Speaker 2 Well, good morning, John. We go to the planet Mars, and many people may wonder, did Mars ever have life? Well, here’s some potential evidence. Many people may not realize this. In 2022, in Africa, in the Sahara Desert, a large two-pound meteorite was found in the sands of the Sahara.

It’s called the Tinkhaza 001 sample. This particular object, John, is actually thought to be a piece of the planet Mars. And this is one of about 435 of these meteorites that have actually come down. How do we know? Because recent analysis, going back to the Viking landers, we find out in this particular meteorite, there are trapped gases and

other components. But the big question, John, should be, How did Mars wind up in a situation where those objects came to the Earth? Something must have hit Mars a long time ago to change its entire history geologically and atmospheric.

A fascinating find.

Speaker 1 Well, I agree with you. I think, and who knows, if life was there, who knows, it might be, you know, a lot of people are saying that one of those moons might be artificial. Who knows?

Speaker 2 We’ll know soon, John.

Speaker 1 We’ll know one of these days. What else, Dr. Skye?

Speaker 2 Well, John, here’s something fascinating for people who talk about the space planes. We’ve been talking about this, the US X-37B, the Chinese so-called secret Shenlong. But here’s something, John, from history. Space planes are not a new idea. The Germans in World War II, with a scientist and aeronautical engineer called Eugene Sanger, he developed a space plane known as the

Silver Bird. What was this? It was to be launched like a rocket, but on a long ramp into the sky. And they call this the New York City bomber. What a crazy title. Why? Because if Germany got the atomic bomb, John, this so-called space plane of the German regime was to drop a bomb on the New York City area. Thus,

it didn’t happen because smarter minds prevailed. But they almost came really close to developing the space plane. And also, as we know, thank God they never got the atomic bomb. But space planes are not that new, John.

Speaker 1 Interesting. What else would you like to talk about? Any special mystery?

Speaker 2 I got a good one, John. Here we go. The mystery of the week. Comets may not have seeded the Earth with life after all. I’ve been talking about this for years, a concept called panspermia, in which comets, when they collided with the Earth billions of years ago, released some basic amino acids for life to form. But new

research claims, it’s pretty obvious, that these comets may not have been able to do this because any of those amino acids would have burned up from the friction of reentry. And that’s an interesting story. The particles in that particular comet were called hydrogen cyanide, also one of the precursors of life. But, John, we figure out that comets may

have seeded life on Mars in the past. Why?

Speaker 2 Because it has less of an appreciable atmosphere. And maybe those comets, if they indeed had the early particles of light, they, of course, may have landed on the surface. But again, John, as we mentioned at the beginning of this update, what caused any life on Mars if it did exist to perish billions of years ago? And the main theory right

now is this, a large asteroid or small planet that probably collided with Mars, sucking up its atmosphere and removing any of the water on the surface. The mystery continues, John, as we explore these great mysteries of the universe.

Speaker 1 Well, I do believe that the planet Earth, that the creator has something to do with it because it’s too perfect and too intermingled to sustain life and protect life. And I’m not sure we’re ever going to find out.

even in our life.

Speaker 2 I know, John, the mystery is big out there. Where did life in the universe come from? It ties into stories of the UAPs, the so-called flying saucers, and we continue to talk about it every week, Friday at midnight into Saturday, and also Saturday midnight to 2 a.m. Sunday on the Dr. Sky Experience. Great mysteries are explored and

stories of American exceptionalism and celebrity guests, and we appreciate the opportunity.

Speaker 1 Thank you, Steve Cates, Dr. Sky, and and hope we can talk more in the future.

Speaker 2 Thank you, John. Have a good Sunday.
