Trappist-1 Exoplanets and Allegro CL - The SIRPASS Story

OAKLAND, Calif. — February 23, 2017 — Astronomers are celebrating a new discovery, a treasure trove of planets found. The big news is that around a very nearby, cold, small star, there are seven rocky Earth-sized planets, all of which could potentially have liquid water. Three of them orbit in the habitable zone around the star. The planetary system is called Trappist-1. JPL's David S. Mittman and STSI's Robert Hawkins have co-authored a white paper that describes the project environment in which the Spitzer Integratesd Resource Planning and Scheduling System (SIRPASS) was developed and used in operations. SIRPASS is the last known adaptation of the Plan-IT II planning and sequencing tool. In the paper, they explain that because the Plan-IT II software architecture utilizes a highly object-oriented design, the core software can be easily extended for specific scheduling problem domains. Plan-IT II is developed in Allegro CL, a dynamic object-oriented development environment for ANSI Common Lisp from Franz, Inc.

SIRPASS is used by members of the Observatory Planning and Scheduling Team to plan, schedule and sequence the Telescope from data made available to them from the science and engineering community. Because of the volume of data that needs to be scheduled, SIRPASS offers a variety of automated assistants to aid in this task. The white paper describes the functional elements of the SIRPASS software system - emphasizing the role that automation plays in the system - and highlights lessons from the Spitzer Space Telescope operations experience.

About Jet Propulsion Laboratory

The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center located in La Cañada Flintridge, California and Pasadena, California, United States. The JPL is managed by the nearby California Institute of Technology (Caltech) for NASA. The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA's Deep Space Network. Among the laboratory's current major active projects are the Mars Science Laboratory mission (which includes the Curiosity rover), the Cassini–Huygens mission orbiting Saturn, the Mars Exploration Rover Opportunity, the Mars Reconnaissance Orbiter, the Dawn mission to the dwarf planet Ceres and asteroid Vesta, the Juno spacecraft orbiting Jupiter, the NuSTAR X-ray telescope, and the Spitzer Space Telescope.

About Space Telescope Science Institute (STScI)

STScI is a multi-mission operations center for NASA’s flagship observatories and a world-class astronomical research center. Established in 1981, the Institute has developed and executed the science program for the Hubble Space Telescope (HST) since its launch in 1990. Today, STScI is developing new technologies for the science and flight operations center for NASA’s next Great Observatory, the James Webb Space Telescope, set to launch in 2018. STScI is also developing major science operations for NASA’s Wide Field Infrared Survey Telescope (WFIRST), set to launch in the mid 2020s, and studying Advanced Space Telescope Concepts for future large missions in the 2030s and beyond.
