Spaceborn Hyperspectral Applicative Land and Ocean Mission (SHALOM) is a joint mission of the Italian Space Agency (ASI) and the Israeli Space Agency (ISA) to develop a hyperspectral satellite for Earth Observation. The Mission, planned to be operative in 2021 with a single satellite, aims at exploiting hyperspectral technologies in the VNIR/SWIR/PAN bands for commercial, scientific and natural disaster applications. The mission was agreed upon in late 2010 and a Joint Definition Phase (JDP) was carried out in 2012-2014 by a Joint Integrated Team (JIT) including Italian and Israeli Industries. The SHALOM B1 Phase shall update and detail the system design and define all operational, programmatic and economic aspects in order to support the Agencies in taking the decision about the complete Mission implementation. The Phase B1 will have duration of 12 months. The JIT is composed by Leonardo, Thales Alenia Space and Telespazio for Italy and IAI / MBT and ELBIT for Israel. During the JDP, a preliminary workshare allocation has been performed by the JIT. This initial joint activity definition was inherently tightly-coupled and required a high degree of interaction and sharing of responsibilities among the different industrial actors. This approach shall be further detailed during the present activities, with the objective to identify clear responsibilities from the technical and programmatic point of view, leading to a complete and unambiguous sharing of the work to be performed. Italian Industry shall have the responsibility for fulfilling the activities relevant to the Overall Payload in VNIR/SWIR/PAN and CAL/VAL activities; Israeli Industry shall have the responsibility for fulfilling the activities relevant to the Satellite Bus, the Payload Telescope and the Panchromatic Camera; A shared Italian-Israeli responsibility shall be defined for fulfilling the other activities relevant to Space and Ground Segment. The mission will acquire: • Hyperspectral (VNIR/ SWIR – 400-2500 nm) images with 10 m spatial resolution in a large number of narrow, contiguous spectral bands (10 nm spectral resolution) using an imaging spectrometer in a pushbroom mode of operation. • Panchromatic images (400 – 700 nm) of the Earth (simultaneous with the hyperspectral measurements) with 2.5 m or 5 m (TBD) spatial resolution. • The hyperspectral images will have a rather high SNR at typical radiance (> 530 @ 550 nm; < 430 @ 1245 nm) thanks to the possibility to perform with the satellite manouvers of Ground Motion Compensation (GMC). The payload, highly integrated in the OPSAT-3000 bus, is mainly composed by a large catadioptric telescope (aperture 650 mm) , two grating spectrometers and a dioptric panchromatic camera. The use of a recurrent platform (mandatory to reduce overall mission development cost) imposes some limitations to the payload budgets (e.g. 120 kg total mass) and therefore a "smart design" and state-of-the-art technologies are needed to achieve the demanding mission requirements.
