A Mission into Hot Phenomena in the Universe is proposed by means of a small telescope of 50 cm aperture accommodated on the International Space Station. Two operating modes are envisaged: 3 angstroms dispersion imaging spectroscopy in the 90-320 nm range (1st priority) or wide field (1°) medium bandwidth imaging in the same range but Ly-α (2nd priority). It will use a pointing platform attached to an Express Pallet Adapter available to the Italian Space Agency (ASI) more than 4-6 months per year. During a life time of 6 yr focal plane instruments may be changed when on-ground refurbishment occurs. With reasonable exposure times hot thermal sources as faint as V = 19-2 can be observed in the spectroscopy mode at 110 nm and active chromospheres on cool stars as faint as V = 15 at 250 nm can be monitored. Assessment of FUV imaging is underway, possibly providing observations of hot sources as faint as V = 21-22. Nominal uplift to ISS is set in Autumn 2005.

Abstract
A Mission into Hot Phenomena in the Universe is proposed by means of a small telescope of 50 cm aperture accommodated on the International Space Station. Two operating modes are envisaged: 3 angstroms dispersion imaging spectroscopy in the 90-320 nm range (1st priority) or wide field (1°) medium bandwidth imaging in the same range but Ly-α (2nd priority). It will use a pointing platform attached to an Express Pallet Adapter available to the Italian Space Agency (ASI) more than 4-6 months per year. During a life time of 6 yr focal plane instruments may be changed when on-ground refurbishment occurs. With reasonable exposure times hot thermal sources as faint as V = 19-2 can be observed in the spectroscopy mode at 110 nm and active chromospheres on cool stars as faint as V = 15 at 250 nm can be monitored. Assessment of FUV imaging is underway, possibly providing observations of hot sources as faint as V = 21-22. Nominal uplift to ISS is set in Autumn 2005.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
