  4. HST: World-Class Science Instrument Cycle 18 (2010-2011) showed the highest over-subscription rate (9:1) in the history of Hubble observations. 1051 proposals were submitted for 23,000 orbits Total Available Orbits: 2,600 Awarded: 1,700 orbits for Small Proposals (under 40 orbits) 300 orbits for Medium Proposals (40-99 orbits) 600 orbits for Large/Treasury Proposal (i.e. M31) ??? orbits for Director’s Discretionary ToO: Target of Opportunity (SNe, comets) Hubble Heritage Outreach Project (15 orbits) >>> 4
