Аннотация:The payload of the UFFO (Ultra-Fast Flash Observatory)-pathfinder now onboard
the Lomonosov spacecraft (hereafter UFFO/Lomonosov) is a dedicated instrument for the
observation of GRBs. Its primary aim is to capture the rise phase of the optical light curve,
one of the least known aspects of GRBs. Fast response measurements of the optical emission
of GRB will be made by a Slewing Mirror Telescope (SMT), a key instrument of the payload,
which will open a new frontier in transient studies by probing the early optical rise of GRBs
with a response time in seconds for the first time. The SMT employs a rapidly slewing mirror to redirect the optical axis of the telescope to a GRB position prior determined by the
UFFO Burst Alert Telescope (UBAT), the other onboard instrument, for the observation and
imaging of X-rays. UFFO/Lomonosov was launched successfully from Vostochny, Russia
on April 28, 2016, and will begin GRB observations after completion of functional checks of
the Lomonosov spacecraft. The concept of early GRB photon measurements with UFFO was
reported in 2012. In this article, we will report in detail the first mission, UFFO/Lomonosov,
for the rapid response to GRB observations.
