Designing a
Industrial Presence on
'The Evening Star'

Creating a plan for a permanent, self sustaining presence on Venus
that harnesses Venusian resources for the benefit of
all terrestrial planets in our Solar System.

Venus is Earth's closest neighbour and one of the least explored. We ask the question
'Is Venus a suitable location for establishing a permanent industrial presence that can feed resources to other planets in place of Earth?' We definitely think so.

Why Venus?

It turns our Venus is quite rich in many available natural resources required to sustain a long term presence in space including being able to offer bountiful reserves of heat, electricity, pressure and industrial chemical precursors dissolved in an easily refined supercritical atmosphere. 

It makes for an intriguing place to consider. Just what resources can Venus offer to us? 

Looking at the Numbers

The case for visiting Venus is strong, but you don't have to take our word for it. Compare the starting paramaters and make your own conclusion.  If you agree that its worth investigating, we welcome your input in the Starship Venus discissions.

Gravity (m/s^2) term exposure to low gravity environments damages human health and some industrial processes need gravity. 
Mean Temperature (deg C)2715-65Mean temperatures closer to that of Earth's reduce themal engineering complexity and energy needs.
Air Pressure (bar)0.510.006Walking on Mars requires bulky full-pressure suits and pressurised habitats. Venus needs only protective gear and breathing support and sealed but not pressurised habitats. 
Atmospheric Mass (kg)4.8 x 10^20 5.1 x 10^18 2.5 x 10^16 The Venusian atmosphere is two magnitudes greater Earth and its at a higher density. As an example even though the atmosphere is only 3% Nitrogen it still contains three times more Nitrogen than Earth's atmosphere.

Generating a habitat atmosphere needs less engineering on Venus than on Mars because the Venusian habitat doesn't require pressurising.  Both need chemical reforming of the habitat gasses, but Mars also needs atmospheric concentration and generation.

Discussion topics we need to address in detail include: 

    How to get there, what's the environment like and what physical properties can we take advantage of. The interplanetary tradeoff is a complicated discussion.  Discuss >
    Humans move to places that efficiently provide them the most resources to thrive. Choices for interplanetary settlements should be no different. Discuss >
    Humans are driven by social and cultural imperatives above all else, as well as the current politically acceptable reasons for space travel. Let us know your reason.  Discuss >
    In-situ resource utilization (ISRU), advanced robotics, habitat design, thermal regulation, electricity generation, drones, variable density atmospheric submersibles, FlyBy mining, corrosion resistance, maintenance, high temperature electronics and closed loop systems will be vital for successful long term presence on Venus. Minimising complexity will be key. The enginerring challenges along with the economic rationale will answer the question, should the presence on Venus be robotic, human or both? Discuss >
    Humans want not just to survive but to thrive in the long term environment. Success will be dictated by physical, mental and spiritual health. Discuss > 

The Evolving Proposal

As our discussion develops, we'll put together interim reports with concrete reasoning for choosing Venus as a place to mine, and send resources to other celestial bodies. The report will provide ever evolving recommendations for exploring Venus. In its final form the report will present a comprehensive mission proposal as a blueprint to visit Earth's closest and richest neighbour. 

Apply for a Position In the Starship Venus Team

We're looking for forum category leaders and also proposal editors for each section of the current proposal. If you work in the space domain, please apply. We regularly publish new position descriptions to the staff section of the forum as they become available.
