NASA’s Astrophysics Investments Website for the Planetary Science Community

Jim Green, Director, Planetary Science Division, NASA
Paul Hertz, Director, Astrophysics Division, NASA

NASA’s Astrophysics Missions are available for the use of the entire science community to advance important science objectives independent of which NASA Division manages the programs.  The planetary science community has benefited from both using the tools and science derived from NASA’s astrophysics investments. This has been occurring for a long time and we want to highlight this great relationship that our two disciplines have continued to develop over the years. We truly believe that the collaboration benefits both scientific disciplines and furthermore, that the best insights comes from interdisciplinary interactions between many scientific fields.

With the goal of engaging the planetary community in taking part in further potential observations from astrophysics missions and continued astrophysics collaborations, we held workshops at the Division of Planetary Science (DPS) meeting through a collaboration of the Astrophysics and Planetary Science Divisions. As a result and with the goal of providing continuous information to the community we are creating a website that would keep updates about the missions proposals schedules as well as links to white papers and presentations that would help our community.

This website is not meant to replace the missions websites, but provide, as much as possible a portal for our community interested in using those investments.

It is quite apparent that we have been experiencing a renaissance of planetary science using astrophysics missions. We deeply appreciate how these two communities of scientists have started to work together in understanding the origin and evolution of our Solar System and all the diversity of objects within. When we look at the sky at night, we now know that the stars we see have solar systems similar to our own.  This is the new paradigm that has drawn us more closely together.

The call for NASA Infrared Telescope Facility semester 2018B observing proposals has been released. The due date for the 2018B semester (August 1, 2018 to January 31, 2019) is Monday, April 2, 2018. Included in this semester is a Comet 46P/Wirtanen campaign, and shared risk use of the recently upgraded MIRSI instrument.  Please see the announcement for available instruments and for further information.

Released: 03/01/2018
Proposal Due: 04/02/2018

The 2017 data release for NEOWISE was in June 2017. The 3-year NEOWISE archive now contains over 7.7 million calibrated image sets and over
57 billion source detections overall. As of mid-September 2017, NEOWISE is 55% into its eighth sky coverage since the start of the Reactivation mission. Over 691,000 infrared measurements have been made of 27,628 different solar system objects, including 735 NEOs and 128 comets.

Time Series Tool

IRSA has a new Time Series Tool:

This tool allows exploration and analysis of time series observations. For WISE/NEOWISE and PTF, users can view measurements as a function of time, simultaneously visualize the single-epoch images, and optionally find the period of variability. Partial functionality is available for other data sets.

This video playlist collects all the relevant movies on the Time Series Tool:

This video describes how to use this tool for Solar System Objects:

IRTF archive coming to IRSA

Starting in Feb 2018, IRSA will host the public archive for the NASA/Infrared Telescope Facility (IRTF). The archive will serve raw data from the SpeX and iSHELL instruments.

IMPORTANT REMINDER FOR JWST Cycle 1 Call for Proposals

IMPORTANT JWST events for the Planetary Science Community

Planning Solar System Observations with JWST in Cycle-1

In light of the April 6, 2018, deadline for JWST Cycle-1 observing proposals, a 4-hour webinar will be held on February 13 from 10a-2p (EST) and will summarize JWST planning tools and their application to observations of solar system targets. These tools include the Astronomer's Proposal Tool (APT), Exposure Time Calculator (ETC), the Target Visibility Tool, and best practices for Solar System proposers.  Operational constraints that affect observations of solar system targets will be summarized and include: bright limits, pointing constraints, track rates, and the impact of ephemeris uncertainties on certain observing modes. Science instrument capabilities and applications will be briefly summarized, but are described extensively in 12 papers in PASP v128, 959 & 960 (2016).

The Online ONLY webinar will be held on February 13, 2018 from 10 a.m.–2 p.m. EST.
