John Batchelor and I welcomed Dr. Jason Kalirai of the Space Telescope Science Institute and member of the WFIRST team to this Hotel Mars double segment.  During the first part of our double segment program, Dr. Kalirai explained WFIRST to us, why and how it differs from other space telescopes including JWST and Hubble and what it can with its new instrumentation such as the Coronagraph and the  Wide Field Instrument.  In addition, Jason talked about the technical specs and capability differences with WFIRST as compared to the other space telescopes.  You can learn much more about WFIRST, the special mission it has, and its value by visiting  For the second segment of the program, we focused on the Dark Energy capability of WFIRST.   As explained to us, WFIRST will carry out three types of surveys to attempt to answer dark energy questions.  More detail about the dark energy capabilities of WFIRST can be found at
