The Road to NASA Administrator | Jared Isaacman Passes Senate Committee AGAIN
Today In Space
Jared Isaacman, previously chosen as the President's pick for NASA Administrator in March 2025, faced the Senate committee hearing AGAIN to discuss his qualifications and potential conflicts of interest before leading the American Space Program. The past year of delay was due to political nonsense, leaving NASA without leadership that whole time. Mr. Isaacman is an entrepreneur, 2 mission astronaut commander, philanthropist, and father who has a unique leadership style. He returned to the Senate Committee sharper than ever! We listen in on the live Senate Committee meeting for some Q&A and...

NASA & Interstellar 3I-ATLAS | Recap w/ My Thoughts & Press Q&A
Today In Space
We went live for the NASA broadcast of the release of images of the Interplanetary "comet" 3I-Atlas, which was delayed due to the government shutdown. As the cultural curiosity surrounding 3I-ATLAS went viral during the poorly timed government shutdown, it was a unique opportunity for NASA to do what it does best. Share data and spend a little more time with the actual experts to explore that curiosity and dig deeper into what we found. Unfortunately, it feels as though the government shutdown and funding cuts proposed by the current President's cabinet was more of an influence on this...

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
