Deadline for submission of abstracts:  10 May 2017

Call for Abstracts for the Tennessee Valley Interstellar Workshop (TVIW) 2017, October 4-6, Huntsville, Alabama

The TVIW conference, titled “Step By Step: Building a Ladder to the Stars,” will be held Oct. 4-6, 2017, at the Embassy Suites in Huntsville, Alabama. The workshop was founded in 2011 by NASA physicist and author Les Johnson; physicist, educator, and author Dr. Greg Matloff; and professional engineer and businessman Robert Kennedy III.

As a Co-Hosting organization of the next Tennessee Valley Interstellar Workshop- 2017, (TVIW), the Tau Zero Foundation (TZF) is issuing our own call for abstracts on specific areas of interest. This special call is in addition to the more general call for abstracts issued from the TVIW hosts, whose topics and conditions can be found here.

Seeding Infrastructure

Many interstellar mission concepts rely on substantial infrastructure in our solar system to build, power, and launch their vehicles. What is seldom addressed, however, is how to begin to build that infrastructure, incrementally and affordably. Abstracts are invited that address that gap, with an emphasis on defining the first infrastructure missions that (a) can be launched with existing spacecraft, (b) provide an immediate utility in space, and (c) are part of a larger plan to extend that capability. This encompasses power production and distribution, mining, construction material processing, in-space construction, and propellant harvesting and delivery.

Exoplanet Science Instruments

What scientific instruments should an interstellar probe carry to collect meaningful information about an exoplanet – information that cannot be obtained from Earth-based astronomy alone? How close would such a probe need to get to an exoplanet to collect this information and how much time will it take within that distance to collect enough data to reach meaningful conclusions? What volume of data would need to be communicated back to Earth? What are projected mass and power requirements for such instrumentation? Abstracts are sought that discuss these instrumentation requirements, characteristics, and the trade-offs between minimizing instrumentation and maximizing information. Papers can be as basic as compiling a list of existing, relevant instrumentation for baseline comparisons, all the way to projections of the minimal mass, power, and computational ability for basic observations. Abstracts are also welcome that discus trends in the abilities of Earth-based exoplanet science and how this affects the instrumentation requirements of interstellar probes.

Foundationally Consistent Baselines

Different mission/vehicle concepts often use different projected performances for common functions such as: (a) heat rejection, (b) energy storage, (c) power management and distribution (PMAD), (d) magnetic nozzles, (e) communication with Earth, (f) equipment longevity, (g) structural mass {if built in space}, and (h) guidance, navigation and control (GNC). Fair comparisons of mission-vehicle concepts are difficult when different values are used for such baseline technologies. Presentations are invited that can credibly delineate reasonable performance estimates for such common functionalities so that future mission-vehicle studies can use common baselines for comparison (e.g. efficiencies, specific masses, readiness levels, etc).

Consistent Comparison Measures

It is difficult to objectively compare different interstellar propulsion and power concepts that use different fundamental methods with method-specific performance measures (e.g. rocket specific impulse, laser pointing accuracy, etc). Abstracts are sought for suggested alternatives to compare both the abilities and resource requirements of diverse interstellar mission concepts – measures that are consistent across all modalities (perhaps in terms of energy, power, mass, mission time, etc.).

Humanities – Interstellar Prerequisite of a Mature Humanity

The energy levels required for interstellar flight are large enough to have the potential to become weapons of mass destruction. Hence, a key prerequisite for achieving interstellar flight is not technical, but societal. Human civilization must mature to where it can wield these energy levels for the greater good instead of on each other. Abstracts are invited that explore these issues in rigorous, academic depth, or suggest how to begin such studies.

Humanities – World Ships as a Crucible of Cultural Study

In addition to the physical life support that has to function reliably for centuries aboard world ships, the culture of the on-board colony will also require a sustainably peaceful governance system along with a culture where the individual citizens live meaningful lives. Abstracts are invited that explore these issues in rigorous, academic depth, or suggest how to begin such studies.

Breakthrough Propulsion Physics

In addition to propulsion and power concepts based on known physics, it is prudent to also consider the possibly that new physics discoveries will lead to breakthrough propulsion, such as faster-than-light transport or propellant-less space drives. Abstracts are sought that identify relevant open questions in physics and then how to further investigate those unknowns. The connection between the open question in physics and its propulsion or power relevance must be explicit. Note, this is not an invitation for new theories or speculations about propulsion devices. Instead, this is a call to identify credible lines of inquiry that might lead to testable, relevant hypotheses. This invitation includes seeking experimental proposals for testing critical relevant questions in physics.


The TVIW is a scientific and educational association that promotes interstellar exploration, travel, and communications. The TVIW provides an opportunity for relaxed sharing of ideas in directions that will stimulate and encourage interstellar exploration including propulsion, communications, and research. The ‘Workshop’ theme suggests that the direction should go beyond that of a ‘conference’. Attendees are encouraged to not only present intellectual concepts but to develop these concepts to suggest projects, collaboration, active research and mission planning. It should be a time for engaging discussions, thought provoking ideas, and boundless optimism contemplating a future that may one day be within the reach of humanity. Though the TVIW concept was intended to be regional (viz., the American Southeast), it is now, in fact, an internationally recognized event.


Abstracts should describe content that can be introduced in a 20 minute presentation, followed by 5 minutes for Q&A. Though not a firm requirement, it is desirable that the author prepare a manuscript suitable for submission to a peer-reviewed journal (such as the Journal of the British Interplanetary Society for general papers). The workshop organizers plan to video and stream the presentations, and share the presentation charts with participants.


Submit 1-2 page PDF including the following information (File size cannot exceed 3 MB):

  • Title
  • Presenting author & affiliation
  • Coauthors and respective affiliations
  • Abstract text between 300 to 500 words in length
  • Outline for the body of the report
  • Cite at least 3 references upon which the work is based
  • Cite the most recent publication by the presenting author that relates to the invited topics

The Tau Zero specific interests are in addition to a more general call for papers from TVIW. If you are submitting an abstract for the more general coverage of the TVIW, then visit the TVIW 2017 general submissions page.

For the Tao Zero specific topics of interest, email your PDF to:

  • 10- May-2017   Submission deadline for TZF Paper Abstracts
  • 31-May-2017    Accepted TZF papers announced
  • 30-Jun-2017    Last day for early registration
  • 30-Sep-2017    Deadline for electronic submittal of all final presentation materials
  • 4-Oct-2017      TVIW 2017 begins

Tau Zero reserves the right to reject any abstract it deems as out of scope or not satisfactorily substantive.It is expected, as a minimum, that abstracts:

  • Address the requested topics
  • Adhere to the submission requirements
  • Reflects that the presentation will be based on sound, credible information instead of speculative or subjective assertions
