Academy track 02

Distance, time & mission physics

Work through light-years, cruise speed, acceleration, braking, energy, waste heat, dust, and the architecture consequences of long travel.

Several generations use an observatory, telescopes, archives, and physical models to study stellar distance and time.
Conceptual fieldDistance, time & mission physicsCelestial positions and model spacing are illustrative.

Editorial boundary: This public alpha is generated from version-controlled source without third-party application or build packages. It is not the reviewed 1.0 corpus: 60 Academy lessons are substantive editorial drafts, 0 remain foundation outlines, and independent domain review remains open.

Core question

How does each extra fraction of light speed reshape the whole system?

Track lessons

  1. Foundation · 28 minutes · substantive-editorial-draft

    Distance and time

    Translate nearby-star distances into transit time, communication delay, generations, and equipment lifetimes without hiding the assumptions.

    Substantive, cited editorial draft; independent domain review remains required.

  2. Technical · 34 minutes · substantive-editorial-draft

    Energy, mass, and momentum

    Calculate ideal kinetic-energy floors, then account for the propulsion, power, heat, shielding, and braking terms those floors omit.

    Substantive, cited editorial draft; independent domain review remains required.

  3. Applied · 32 minutes · substantive-editorial-draft

    Acceleration and braking

    Treat acceleration, thrust reversal, capture, human exposure, and failed braking as one arrival architecture rather than an afterthought.

    Substantive, cited editorial draft; independent domain review remains required.

  4. Applied · 34 minutes · substantive-editorial-draft

    The medium is not empty

    Connect sparse interstellar gas, dust, plasma, cosmic radiation, speed, frontal area, shielding, sensing, inspection, and repair.

    Substantive, cited editorial draft; independent domain review remains required.

  5. Foundation · 32 minutes · substantive-editorial-draft

    Reference missions and honest comparisons

    Compare flown spacecraft and paper studies without treating a fast flyby probe, Solar System precursor, or habitat sketch as a demonstrated generation ship.

    Substantive, cited editorial draft; independent domain review remains required.

Scope: Academy track mission-physics

Page citations and accountability links

Assumptions and limits

  • The track is organized around the question: How does each extra fraction of light speed reshape the whole system?
  • The track overview summarizes linked lessons and systems; it does not create a new evidence grade or independent-review state.

What would change this page?

A changed track scope, lesson evidence, capability dependency, curriculum review, or audience need would trigger revision.
