  We will present an overview for iSHELL, MINERVA-RED, and results from a
  prototype precise radial-velocity (PRV) survey with CSHELL. With CSHELL at the
  NASA Infrared Telescope Facility atop Mauna Kea (R~46,000), we have completed
  a PRV 2.3 mum survey to detect exoplanets around ~30 red, low mass, and young
  stars. We are able to reach long-term radial velocity dispersions of ~30 m/s
  on our survey targets. We are following up a few candidate RV variables, and
  have confirmed other RV variables. With a spectral grasp of only 5 nm at 2.3
  mum, this performance with CSHELL is limited by detector artifacts, and
  fringing in the data and flatfields.  

  iSHELL will replace CSHELL at IRTF, with first light expected in April 2016. 
  iSHELL is a 1.15-5.4 mum high spectral resolution (R~70,000) immersion
  grating, cross-dispersed, white pupil spectrograph. About $4 million in
  funding has been provided by NSF, NASA and the University of Hawaii. Based
  upon our experience with CSHELL, we should be able to obtain a precision of
  less than 5 m/s in the NIR with iSHELL from the improvements in spectral grasp
  alone.  

  Finally, MINERVA-Red is a project to use a dedicated, robotic, near-infrared
  optimized 0.7 meter telescope and a specialized Doppler spectrometer to carry
  out an intensive, multi-year campaign designed to reveal the planetary systems
  orbiting some of the closest stars to the Sun. The MINERVA-Red cross-dispersed
  echelle spectrograph is optimized for the 'deep red', between 800 nm and 900
  nm, where these stars are relatively bright. The instrument is very compact
  and designed for the ultimate in Doppler precision by using single-mode fiber
  input. We describe the spectrometer and the status of the MINERVA-Red project,
  which is expected to begin operations at Whipple Observatory on Mt Hopkins,
  Arizona, in fall 2015.
