Development of a space-based economy, space settlement, and space news

Space news

The following are recent presentations on space-related news, made to the North Houston chapter of the National Space Society.  Most are saved in pdf format, and can be viewed simply by clicking on the link.  However, a few presentations include gif animations, which don’t work in pdf viewers.  In that case, the format is a Powerpoint presentation, which you may have to download to view.  To see the animations in Powerpoint, you may need to click on the picture, or go to “slide show” mode.  Even if you haven’t previously installed Microsoft Powerpoint, you can download and use a read-only version of Powerpoint for free from Microsoft.

Presentations on space-related topics

Presentations on specific topics related to the development of a space-based economy and settling in space are:  

Biosphere 2 and closed ecological systems:  systems biology for sustainable life outside earth, and a space settlement prototype 30 years ahead of its time

Biosphere 2 was constructed as a demonstration/test site for prototyping sealed life support systems to support future space colonization, and to better model how earth’s ecosystems work. 8 people were sealed in the 3.14 acre facility for 2 years starting in 1991.  It holds the record as the world’s largest and longest-running closed environment test.  The facility is still there and open to the public, although it is no longer sealed. The presentation Biosphere 2:  A space settlement prototype 30 years ahead of its time (pdf) offers a retrospective on its unique contributions to understanding the complexities of sustaining life outside earth.  The presentation was to the AIAA (American Institute of Aeronautics and Astronautics) Annual Technical Symposium (Houston),  October 24, 2020.  There also a video of the AIAA Biosphere 2 presentation on the Houston AIAA site.

Lunar gateway orbit options

The “lunar gateway” has gone through various name changes over time.  If it is built, it will be a small-scale, short term human habitat orbiting the moon (also called “cis-lunar space”).  An overview of the issues in choosing an appropriate orbit is given in this Lunar gateway orbit options presentation (Powerpoint) from January, 2019.  The presentation includes some animations.  To see those, you may need to go into “slide show” mode.

SpaceX’s StarLink and other satellite-based internet services

StarLink is a satellite-based worldwide internet service being built by SpaceX.  It was initially envisioned to be based on up to 12,000 Low Earth Orbit (LEO) satellites, although there is now an application to increase this to 30,000 satellites.  By comparison, there were only about 5000 satellites in orbit at the time of the first launch.  There are other competitors who also are launching large numbers of satellites in the race to provide space-based internet service.  This StarLink presentation (Powerpoint) from June, 2019 provides an overview.  The presentation includes some animations.  To see those, you may need to go into “slide show” mode or click on the picture.
