Bookmark Bookmarks Find it Again help

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.

This post is reserved for an index to posts that may be contributed by members.

Since this post must be maintained by moderators, it is unlikely to stay up with the flow of traffic, but it may provide a quick lookup capability to the extent it is maintained.

The ** main ** purpose of this new topic is to enable individual members to create their ** own ** bookmarks.

If those bookmarks are helpful to others, that's a bonus.

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 LEO

Update 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 link takes you to the first article that includes ssto:

This link takes you to the article itself.

Re: Bookmark Bookmarks Find it Again help

This bookmark is for one of a great number of interesting posts by Photonbytes

https://newmars.com/forums/viewtopic.ph … 46#p205246

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.
