Exoplanet Science with the Nancy Grace Roman Space Telescope

Noon-12:30 pm EST/8-8:30 am PST 

Join NASA Deputy Program Scientist for the Nancy Grace Roman Space Telescope, Aki Roberge, to learn how Roman will conduct the definitive survey of cold exoplanet demographics and provide the first space demonstration of active coronagraphy to study exoplanets.

As a science support center for the mission, IPAC is responsible for operations for the Coronagraph Instrument (CGI), including commanding and performance monitoring, high-level data processing of the grism and prism data from the Wide Field Instrument (WFI), high-level data processing of the microlensing survey data from WFI, proposal selection, and community engagement for exoplanet science.

The Keck Observatory Archive
G. Bruce Berriman (Caltech/IPAC-NExScI)

1-1:30 pm EST/10-10:30 am PST Watch Recording

The Keck Observatory Archive (KOA) is a collaboration between the NASA Exoplanet Science Institute and the W. M. Keck Observatory to archive and serve data from the two 10-meter Keck telescopes. For over 26 years, the powerful instruments deployed on these telescopes have observed solar system objects, brown dwarfs, exoplanet systems, star clusters, galaxies, quasars, and more! Over 3.4 million raw files are available for YOUR science and KOA has the tools to help you find the ones you need. Watch our webinar or visit our virtual booth (Caltech/IPAC Data Archives) for more information.

SOFIA Archive Opportunities: Science-Ready Data and Funding
Ed Chambers (SOFIA/USRA), Luisa Rebull (Caltech/IPAC-IRSA), B-G Andersson (SOFIA/USRA)

The SOFIA Archival Research Program (SARP) is now open for proposals to fund research projects primarily using SOFIA data. The purpose of this program is to encourage the use of available SOFIA archival data and to realize the full potential of the SOFIA archive. In this webinar we will present the search and visualization functionalities for SOFIA data in the IRSA archive, highlight and describe select high-potential public datasets, and discuss the mechanics of the open funding call.
US Archival Science with Euclid

Harry Teplitz (Caltech/IPAC-Euclid), Phil Appleton (Caltech/IPAC-Euclid), James Colbert (Caltech/IPAC-Euclid)

4:30-5 pm EST/1:30-2 pm PST   Watch Recording

Euclid is an ESA mission, with NASA involvement, to study the nature and geometry of the dark universe, with launch planned in mid-2022. Euclid will survey the extragalactic sky, obtaining near-infrared and wide-band optical imaging, as well as NIR grism spectra. All Euclid data will be made public to the world-wide community within 2 years of acquisition. The Euclid NASA Science Center at IPAC (ENSCI; will support Euclid research by the US community. In this webinar, we will give an overview of the mission and the opportunity for US-based archival research.


Using Python to access NASA Archives
David Shupe (Caltech/IPAC)
4:30-5 pm EST/1:30-2 pm PST   Watch Recording
This webinar will feature experts from the NASA Astronomical Virtual Observatories (NAVO) Python working group. There will be a short tutorial on how to access the NASA Archives using the pyvo package. Under the hood, this package uses Virtual Observatory protocols so that the user does not need to know where the data are hosted but can discover what is available and access it in standard ways. A 15 minute general Q&A session will follow. NAVO comprises elements of MAST at STScI, HEASARC at GSFC, and both IRSA and NED at IPAC.

Session: Surviving and Thriving in Rejection

Noon–1:30 pm EST/9-10:30 am PST

D. Gelino

A "no" does not mean a no forever. It just means a no for now. A rejection is often simply an issue of resource allocation in this time and space. But how do we manage multiple rejections, especially as we may be facing a challenging job market? How do we build resiliency, and ensure that we do not equate a rejection with any measure of our self-worth? In our conversation, we will address how to manage rejection with a positive attitude and become persistent.
