Chicago Pile-1 First Criticality — birth chart across three traditions

Born: 1942-12-02 at 15:25 · Stagg Field, Chicago, Illinois, USA

Data source: Rodden AA (announced and logged on the day by Fermi and the assembled team).

The first self-sustaining nuclear chain reaction, in a squash court under the west stands of Stagg Field. The source states the local hour; the United States kept year-round war time in December 1942, so Chicago was UT-5 and 15:25 local is UT 20:25.

Reading the chart

Sagittarius Sun, Libra Moon, Taurus rising — a day chart, led by the Sun's agenda.

Mars carries unusual weight here — in an angular house (7); strong essential dignity (domicile).

Stellium in Sagittarius: Sun, Mercury, Venus — a concentrated emphasis that colors the whole chart.

Fire is the leading element (38% weighted), while earth is least emphasized — a texture worth noticing, not a verdict.

Mutable modality leads: the chart's default rhythm is adapting — adjusting and redistributing energy.

Chart ruler: Venus in Sagittarius, house 8 — where this planet acts, the chart's agenda advances.

Planetary distribution: locomotive — planets cover two-thirds of the wheel; the leading planet drives the chart.

Sun at 10°02′ Sagittarius, house 8: core identity, vitality and sense of purpose operates expansively, candidly, aimed at the far horizon — the keynote is meaning. The main arena is shared resources, intimacy and deep exchange.

Moon at 0°49′ Libra, house 6: emotional life, instinct and the need for safety operates relationally, aesthetically, by weighing and balancing — the keynote is equilibrium. The main arena is work routines, health habits and service.

Stellium in Sagittarius: Sun, Mercury, Venus — a concentrated emphasis that colors the whole chart.

Sun conjunction Mercury (orb 0°59′, separating): Sun and Mercury fuse — these functions operate as one package, for better and for richer.

Moon conjunction Neptune (orb 0°58′, applying): Moon and Neptune fuse — these functions operate as one package, for better and for richer.

Sun opposition Saturn (orb 1°05′, separating): Sun and Saturn face each other across an axis — awareness tends to arrive through other people and counterweights.
