Summary of Some ULA Papers from AIAA SPACE 2015

ULA has often used the AIAA SPACE conferences as a venue for discussing technical ideas they were working on. In fact, I’ve written several blog posts over the years summarizing or commenting on previous versions of their papers. This year’s … Continue reading

Boomerang Air-Launched TSTO RLV Concept Part III: Carrier Plane Support Subsystems

Before getting into my thoughts on potential options for the carrier plane itself, I wanted to mention a few nice-to-have options for the carrier plane itself. I don’t know that any of these is strictly required, but all potentially help: … Continue reading

Boomerang Air-Launched TSTO RLV Concept Part II: Carrier Plane Gamma Maneuver Safety Considerations

In this post I would like to discuss some of the key considerations and options governing the carrier plane for my Boomerang TSTO RLV concept. Specifically I’ll be covering considerations relating to safely supporting the Gamma Maneuver, and useful support … Continue reading

Boomerang Air-Launched TSTO RLV Concept (Part I)

Back when I left Masten to start Altius, I originally thought I was starting a launch vehicle company focused on reusable nanosat launchers. While we pivoted away from that to focus on space robotics, I’ve continued to dabble with a … Continue reading

Random Thoughts/Orbital Access Methodologies VII: Air-Launched Glideforward TSTO with Exo-atmospheric Suborbital Refueling

Ok, I’ve been toying with another orbital access methodology, but I wasn’t sure whether to file it under Random Thoughts (which tend to be my more half-baked, far-out ideas) or with the rest of the Orbital Access Methodologies series (which … Continue reading

Orbital Access Methodologies Part VI: Air-Launched Glideforward TSTO

Back when I first gave the guest-lecture at the University of North Dakota that kicked off this series, I had only introduced four actual technological approaches to making RLVs work. The balance of the time I spent talking about the … Continue reading

Orbital Access Methodologies Part IV: Glideback TSTO

Some of the comments to my last post got me thinking about what I’m trying to accomplish with this series. The reality is that each of these approaches that I’m discussing could easily fill a full chapter in a textbook, … Continue reading

Orbital Access Methodologies Part III: Pop-up TSTO

This third installation in my Orbital Access Methodologies series (parts I can be found here, and part II here) has been a long time in the coming. It has taken so long, not because I’ve been spending months researching and … Continue reading

Orbital Access Methodologies Part II: The Key Challenge of TSTO RLVs

Before I go into detail on any of the two stage to orbit (TSTO for the uninitiated) approaches that I mentioned in my post last week, I’d like to briefly discuss what I think is the key issue that drives … Continue reading
