  1. Science investigations in the framework of expedition to Europa L. Zelenyi et al

  2. News • Split of EJSM into JUICE (ESA) and some independent study by NASA (see JPL talks later) • JUICE: launch 2022 (2023) • Callisto phase • 2 Europa fly-bys • Ganymede phase • Crush into Ganymede • Continued assessment of Europa Lander mission 2009-2012

  3. JUICE model payload

  4. Development: 2008: Preliminary assessment 2008: Initial industrial study 2008 2009: Europa Lander workshop 2009 2010: radiation load/scenario/landing site assessment; lander payload definition 2011: further scenario development; orbiter payload definition; payload accommodation Present mission architecture: Europa lander, full mass 1210 kg, target 50 kg of mass for science Telecom and science orbiter, 50 kg science payload Multiple fly-bys of Ganimede, Callisto and Europa; Final circular orbit around Europa with a height of 100 km; Soft landing, target surface mission duration 60 days. Surface analysis by drilling (30 cm depth) possibly melting probe (<5 kg). Orbiter supports telecommunication. Optional TM directly to Earth via VLBI Target total radiation dose <100kRad behind 5 g/cm2 Al (300 kRad tolerant components) Laplace-Europa Lander mission: Development Roscosmos IKI TSNIIMASH Lavochkin Assoc

  5. Resources: 50 kg on the lander, including sample handling and (partially) radiation shield 3.2 kbit/s via HGA to 70-m dishes Lander data relay via orbiter 50 kg on the orbiter, including (partially) radiation shield Goals: The main appeal of the present mission is search for life on or its signatures on Europa Sample acquisition, concentration Subsurface access Establishing geophysical and chemical context Biology-driven experiments should provide valuable information regardless of the biology results Lander is to provide ground truth for remote measurements and enhance the detection limits Orbiter: versatile remote observations; landing site characterization; Jupiter science Laplace-Europa Lander mission: Science Proof-of-the-concept payloads Lander: • 12 instruments  20 kg • 4-5 kg melting probe • Drill for 30-cm depth Orbiter: • 6 instruments, incl. radioscience Roscosmos IKI TSNIIMASH Lavochkin Assoc

  6. Example payload for Europa lander 20315g Roscosmos IKI TSNIIMASH Lavochkin Assoc

  7. JUICE considered scenario: Focus on Ganymede Callisto Jupiter 2 Europa fly-bys Cooperation options: Laplace in present form with Europa landing emphasis and relay orbiter; science cooperation and science instruments exchange. Coordinated observations of Ganymede Landing on Ganymede; possible relay via JUICE JUICE – Laplace cooperation options EJSM  JUICE consequences of JEO loss • Drastic decrease of Europa science • Non-compromised Ganymede and Jupiter science Roscosmos IKI TSNIIMASH Lavochkin Assoc
