The High Frontier

Checkout the trailer for the upcoming documentary The High Frontier: The Untold Story of Gerard K. O’Neill which was shown for the first time yesterday on the live stream of Yuri’s Night annual celebration party. The trailer begins with an introduction by Rick Tumlinson at 2:57.

Executive order authorizes the commercial use of space resources

The document states that “Americans should have the right to engage in commercial exploration, recovery, and use of resources in outer space, consistent with applicable law. Outer space is a legally and physically unique domain of human activity, and the United States does not view it as a global commons. Accordingly, it shall be the policy of the United States to encourage international support for the public and private recovery and use of resources in outer space, consistent with applicable law”

New space solar power company down under

Solar Space Technologies (SST), a recently-formed Australian company, is planning the development of a solar power satellite (SPS) system to provide electricity for Australia. The new company is developing the technology for deployment of an SPS, ground receiver sites and associated infrastructure. SST’s system would generate a total capacity of at least 18 gigawatts for the Australian electricity market which could also potentially be exported to other countries. In less than a decade, SST proposes the creation of an Australia-US public/private partnership, with additional participation by Japan, Canada, New Zealand and others for development of the SPS. A downloadable Executive Summary Brochure is available from the company website.

New L5 space settlement concept published by NSS

The spinning dual-sphere orbital colony would house 200 settlers completely shielded by asteroid material and under 1G artificial gravity. The business case is promising if launch costs come down to $300/kg. The new paper was just posted on the NSS Space Settlement Journal, an open access journal chuck full of papers on space settlement enabling technologies.

Best practices and standardization for space operations

Since the USSR launched Sputnik in 1957, the number of satellites in LEO has grown leading to an increasing threat of collisions. The Space Safety Coalition, a confederation of voluntary participants, has established a set of guidelines to mitigate the risk of interruption of vital space services that could arise if collisions occur. The SSC published the Best Practices for the Sustainability of Space Operations in September 2019 with 42 recommendations affecting not only the design of spacecraft but on-orbit procedures to ensure long term safety and sustainability.

Interstellar travel using Q-Drive

An analysis of this innovative propulsion system credited to Jeff Greason of the Tau Zero Foundation is provided by Alex Tolley. The method for powering a starship saves fuel by extracting energy from plasma streams in the interstellar medium (or closer to home, from the solar wind) and converting it to momentum using onboard fuel to propel the ship. Although there are engineering challenges, the physics is sound and the savings in fuel enables the system to accelerate payloads to 20% of the speed of light.

MAXIM – Maximum Impact Moon Mission

The University of Southern California’s Department of Astronautical Engineering has just published the final report of Dr. Madhu Thangavelu’s, course ASTE 527 Space Concepts Studio, the theme of which features the MAXIM architecture proposed for NASA’s Artemis program for return of humans to the moon. Be sure and watch the recorded presentation of the report which features the classic video “Wanderers” with commentary written and narrated by Carl Sagan. The class is held each fall and has an archive of each year’s reports, an excellent repository of creative concepts for space development.
