Using Practical Tech | AI - The Good, The Bad, and The Ugly
Today In Space
This week, Alex shares his thoughts on practical uses of technology. As an engineer, it's hard not to focus on how technology could be useful. On today's episode, we're talking about AI and the good that can come from practical daily use of it. But, we're also talking about the bad and the ugly that comes with using it, and how most of Alex's perspective on the future of AI comes from playing 'Megaman: Battle Network' as a teenager. As AI Tools enter the market more and more (and are embedded into more products) it's important to discuss all aspect of it, the good the bad and the ugly. Alex...

The Space Conundrum & Blue Origin NS-31 the All-Female Flight to the Edge of Space
Today In Space
6 Women took flight on Blue Origin's New Shepard rocket to the edge of space and a powder keg of hype and celebrity blew up the internet. Something about this all-female mission triggered people from all sides, with many jumping on the trend or not even realizing this billionare space race has been underway for a while (or even what the Karman line is). This episode lays out some basic facts about the mission and dedicates coverage of the two women with (IMO) the most powerful stories of the NS-31 crew, Aisha Bowe and Amanda Nguyen. These are chaotic times, with people chasing the algorithm -...
info_outlineOn today’s episode, we’re diving into what’s going on with Near-Earth Asteroid 2024 YR4. You may have heard online that this asteroid is on a trajectory to impact Earth on December 22nd, 2032. It’s captured the zeitgeist and everyone’s talking about it.
But what can we do in the meantime? We say - Let’s learn! We need to science the $%#t out of this one! We’re going to explore the idea of planetary defense, the level of impact if it does hit Earth in 2032, and how lucky we are to have successful missions like DART and HERA to lean on for our “armageddon” moment.
We'll also try to answer these questions:
- What is the Asteroid?
- What is the impact potential on Earth?
- How was it discovered?
- Why do the impact probabilities keep changing?
- What can we do about it?
- Why don't we just NUKE it?
Keywords:
asteroid 2024 yr4, planetary defense, impact probability, kinetic impactor, Dart mission, Hera mission, James Webb Space Telescope, automated detection, NASA funding, public interest, Tunguska event, city killer, orbital changes, nuclear option, planetary defense systems
Timestamps:
00:00 Asteroid 2024 YR4 Overview and Initial Concerns
03:03 Discovery and Initial Observations
05:30 Probability Changes and Data Limitations
07:25 Public Interest and Planetary Defense
10:35 Kinetic Impactor Defense and Future Missions
Here's to building a fantastic future - and continued progress in Space (and humanity)! Spread Love, Spread Science
