This topic is offered for NewMars members who would like to find posts in future.
Occasionally members create posts that are worth rereading at a later time.
The forum has no mechanism in place to find posts easily.
The Search tool is a powerful tool, but it is only as good as the memory of the user.
In addition, search terms we might try often deliver many unrelated posts we have to sift through.
There is a time honored mechanism that SpaceNut just reminded me to consider: bookmarks
in the physical Real Universe, a "bookmark" may consist of nothing more complex that a slip of paper sticking out from between two pages.
In the digital realm, this topic is offered as a way for each member to store a reminder of where a particularly interesting or valuable post may reside.

Rocket Equation exercise with gravity and drag
This study compares SSTO and TSTO and concludes that SSTO is feasible if the vehicle is left in orbit (ie, expendable).
A reasonable scenario for that case is the material of the rocket is intended to be used after delivery to LEO.
The blogspot site has a search window in the upper left corner. Like the NewMars search tool, it is a crude instrument, but it ** did ** find an article in which SSTO is included.
Interestingly, the article cited is a follow up to the one I was looking for:

More-Refined 1- vs 2-Stage to LEOUpdate 6-8-2025: this article is the continuation of a study originally posted 3 March 2024, titled "Launch to Low Earth Orbit: 1 or 2 Stages?". That study produced some broad recommendations, this one produces actual trends of payload fraction and launch weight vs propellant combination, for the all-expendable TSTO and SSTO scenarios.

This one shows a proposed SSTO vehicle with reusability features. Because we know that this design is unlikely to fly as an SSTO, it is of historical interest as an example of ambitious thinking. However, the vehicle seems feasible for a TSTO configuration, especially if the first stage is itself reusable.
