  • Not Spacy but love the Podcsdt

    I listen to the first half of this podcast every weeknight. I am not in the space industry and know little about it but I find the news updates fascinating. I feel like I’m learning and I had no idea of the rich news about space there is. Sometimes I listen to second half of the show but not always. A lot of that is a little “in the weeds” for me.

Talking Points

Recent interactions between the hosts and their guests.

Ordering a new space policy.
Q: Why don't you, can you try to walk me through this one?
Cook describes “Ensuring American Space Superiority” as a broad policy-setting order covering national security, commercial investment, U.S. space strategy, a return to human space exploration, Mars missions, and a permanent lunar outpost.
Ordering a new space policy.
Q: What the heck an executive order is and what it isn't?
Cook explains that an executive order is a written directive from the executive branch to its agencies, not legislation passed by Congress. It can carry the force of law when legally issued, but a subsequent president can revoke it.
Expanding America’s space capabilities.
Q: Now, what does that mean? The QCADDS?
Cook says QCADDS stands for the Quantum Computer for Application Development and Discovery Science effort, a national initiative to enable a quantum computer for scientific discovery.
Expanding America’s space capabilities.
Q: So what is the proclamation? What's the difference there?
Cook explains that a proclamation is less binding than an executive order and is easier to issue, describing it as a statement of what the administration intends to do.
Earth’s expanding attack surface.
Q: What advice do you give people looking for a job in the space industry as an InfoSec professional?
The space industry is largely compliance-driven, so many roles emphasize auditing and meeting requirements, with some testing components; newcomers should build knowledge around standards and regulatory frameworks and gradually gain hands-on experience within those boundaries.
