Discussion Overview

The discussion revolves around the Pale Blue Dot Project, which aims to develop a space telescope to image Earth-like planets, specifically targeting the Alpha Centauri star system. Participants explore the feasibility of using an 18-inch mirror for this purpose, comparing it to other telescopes like the James Webb Space Telescope.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants question whether an 18-inch mirror provides sufficient resolution for imaging exoplanets, suggesting it may be too small compared to other telescopes.
  • Others express skepticism about the project's ambitious funding goals and timeline, noting the need for $175,000 to define the project and a projected total cost of $50 million.
  • A participant points out a potential confusion between the Pale Blue Dot Project and other similar initiatives, providing links for clarification.
  • One participant mentions a Space Act Agreement between NASA and the BoldlyGo Institute, indicating institutional support for the project.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the adequacy of the 18-inch mirror for the project's goals, with some expressing skepticism while others provide context about the project's support and funding.

Contextual Notes

Participants have not fully explored the technical specifications or limitations of the telescope design, and there are unresolved questions about the project's feasibility and timeline.

Apparently there's something called the pale blue dot project that needs funding to image an Earth like planet in a nearby star system. I asked them of the lens diameter and they replied that the telescope will use a 18" mirror. Is that enough resolution wise? Seems a little small when you compare it to James Webb or other planet searching telescopes.

Apparently this is a crowd sourced attempt to develop and launch a space telescope dedicated to finding a hospitable planet around Alpha Centauri.

They're currently trying to raise $175,000 to define the project and establish industry relationships. The mission is expected to cost around $50 million and they're projecting a 2021 launch. Seems a bit ambitious to me.

In my opinion though a 18" mirror is not even close to what's needed to image an exoplanet. I'd like to invest in this but I'm fairly skeptical.
