Orbit & access
- Orbit
- Mean distance: ≈ 212,300 km from Saturn; Orbital period: ≈ 1.16 days.Source: [3] NASA JPL Solar System Dynamics
- Accessibility (Δv / travel time)
- Model assumptionAbout 13.6 km/s of ideal Δv from low Earth orbit (7.29 km/s to depart + 6.30 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
- Cassini flybys: 16 Oct. 2010 (36,000 km); 14 Sept. 2011 (44,000 km); First photographed: Possibly by Voyager 2 on 23 Aug. 1981.Source: [1] Wikipedia, [2] NASA Science
Resources & economy
- Believed resources
- Model assumptionOur model looks at water / volatiles for propellant and life support. Usable fraction assumed at 0.1–0.3 of extracted material (bear to bull). Very low density suggests ice-rich, porous material, but ice fraction is not measured; 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 −$2,139M (bear), −$1,037M (base) and $4,937M (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.
- Business uses
- Information products, science partnerships, and a (very long-shot) in-space resource case. See the Business page. Open →
