I. Zimovets1, L. Zelenyi1, V. Kuznetsov2 & the IHP Team1,2,… 1 Space Research Institute (IKI), Russian Academy of Sciences, Moscow, Russia 2 Institute of Earth magnetism, ionosphere and radiowaves propagation (IZMIRAN), Troitsk, Russia ESPM-14, Trinity College Dublin, Ireland (11:20-11:40, 08-Sep-2014) Current state of the Interhelioprobe mission
Concept of the Interhelioprobe (IHP) mission • Multi-wavelength solar observations at short distances from the Sun (up to ~60RS or ~0.28 AU) • Out-of-ecliptic solar observations (up to ~30°) and from the opposite (“dark”) side • In situ measurements in the inner heliosphere (and) out of the ecliptic plane (Similar to the concept of the Solar Orbiter)
General information about the Interhelioprobe mission Initial idea:IZMIRAN, IKI (mid-90s) Leading scientific organization:IKIsince April 2013 (IZMIRAN before) Principal investigators:Dr L. Zelenyi (IKI) &Dr V.Kuznetsov (IZMIRAN) Launch date:shifted from 2018 to 2022 (reserve launch in 2023) Launch by:the “Soyuz-2/1b” rocket with the “Fregat” rocket stage from Baikonur • Number of spacecraft: 1 (currently) or • 2 (under consideration, decision in 2015) • Active operation time: 5 years • Current stage:beginning of Phase C (contract signed on 28-May-2014) • drawings, development of the structural, thermal and engineering • models of the scientific instrumentation (2014-2015)
General information about the Interhelioprobe mission Funding: Russian Federal Space Agency (Roscosmos) Spacecraft design:Lavochkin Research and Production Association (NPO Lavochkin) Scientific instrumentation design: IKI, IZMIRAN, NIRPhI, LPI, SINP/MSU, MEPhI, IPTI + + International collaboration (Poland, France, Germany, Czech Republic, Austria, Ukraine, UK) Scientific payload: 10 remote-sensing instruments + 9 in situ instruments Mass of the scientific payload:160 kg (with cables) Telemetry: 1 Gb/day Similar projects:SolarOrbiter - SolO, ESA(2017) Solar Probe Plus - SPP, NASA (2018) Solar Polar Orbit Radio Telescope – SPORT, China (2020?)
