Mar 22, 2017- As planned, the SPHEREx team responded in writing to resolve
NASA's questions about potential major weaknesses in our MIDEX proposal.
This is standard procedure for MIDEX proposals at this stage.
Jan 4, 2017 - We are disappointed not to have been selected as a NASA SMEX
this round. NASA chose the
Imaging X-ray Polarimetry Explorer
(IXPE), a mission led by Marshall Space Flight Center. We wish them the very best of luck.
Dec 15, 2016 - An enhanced version of SPHEREx was submitted as a NASA
Medium-Class Explorer (MIDEX),
with Step-1 selections expected in July 2017. If approved, the augmentations will make SPHEREx
a significantly more powerful survey telescope for the astronomical community as a MIDEX.
Jul 18, 2016 - The SPHEREx step-2 proposal Concept Study Report was submitted to NASA!
Jun 16, 2016 - The detector sampling algorithm to be implemented
by SPHEREx has now been described in detail by
Zemcov et al., 2016,
now accepted by JAI!
Feb 24-26, 2016 - The SPHEREx team held a very successful
community-oriented science workshop at CalTech.
It was attended by more than 50 scientists from a wide range of disciplines,
including galactic, extragalactic, and planetary science. A
describing the science topics was recently posted on arxiv. The attendees on day two:
Nov 6, 2015 - SPHEREx will be featured at the upcoming January AAS meeting in Kissimmee, in session 147 on Tuesday January 5. In addition to the SPHEREx observatory and the all-sky spectral survey, the presentations will describe the three main research themes being developed by the SPHEREx science team, and the many science opportunities that SPHEREx will create for the wider astronomical community.
Oct 23, 2015 - PI Jamie Bock summarized the status and goals of SPHEREx to NASA's Astrophysics Subcommittee. The full presentation can be downloaded here.
