Saturn XXXI · S/2003 S 1
Introduction
- Type
- Irregular, retrograde moon of Saturn; Group: Norse group; subgroup with Bestla.Source: [1] Wikipedia, [2] NASA Science
- Discovery
- Discovered: April 8, 2003 (images Feb.–Apr. 2003).Source: [2] NASA Science
Physical
- Size
- Diameter: ≈ 7 km.Source: [1] Wikipedia
- Mass
- Not measured in our sources.
- Rotation
- Rotation period: ≈ 10.21 hours.Source: [1] Wikipedia

Orbit & access
- Orbit
- Mean distance: ≈ 19.3 million km from Saturn; Orbital period: ≈ 1,000 days; Inclination: ≈ 142° (retrograde); Eccentricity: ≈ 0.44.Source: [3] NASA JPL Solar System Dynamics
- Accessibility (Δv / travel time)
- Model assumptionAbout 11.7 km/s of ideal Δv from low Earth orbit (7.29 km/s to depart + 4.39 km/s to arrive), and about 6.1 years for an ideal transfer.Model calculation from our Space Resource Intelligence (SRI) sample report: ideal transfer to the parent planet, then capture into this moon's orbit; no gravity assists. Real trajectories differ.
- Mission history
- No spacecraft visit is listed in our sources. What is known comes from telescopes.
Resources & economy
- Believed resources
- Model assumptionOur model looks at water / volatiles for propellant and life support. Usable fraction assumed at 0.02–0.1 of extracted material (bear to bull). Composition of small irregular moons is unmeasured; water content is a pure SRI assumption.SRI sample-model assumption, not a measurement.
- Economic outlook
- Model assumptionScientific value now; any resource value is long-horizon option value. Our sample model gives an NPV of about −$2,003M (bear), −$1,150M (base) and $1,186M (bull).Model output from our SRI sample valuation model (launch, product value, transit, extraction and discount-rate inputs are scenario assumptions, not forecasts). Not investment advice.
