IPAC, located on the Caltech campus, is not under direct threat from local fires at this time, though it is subject to the effects of strong winds and poor air quality. Many members of the IPAC community have been impacted by these events, and IPAC will follow Caltech guidance on closures and safe operations.

Missions & Centers

IPAC is home to the science operations center for the Spitzer Space Telescope. Spitzer is one of four of NASA's Great Observatories, and will continue to operate in its “Beyond” mission phase until its successor the James Webb Space Telescope has completed commissioning in 2019. IPAC also is home to NExScI, the science operations and analysis center for NASA's Exoplanet Exploration Program, as well as science centers serving the US community which support NASA partnerships with ESA on the Herschel and Planck missions. Support for NASA's NEOWISE mission to discover and characterize near-Earth objects rounds out IPAC’s current mission support portfolio.

Euclid
Euclid NASA Science Center at IPAC

Euclid is a European Space Agency (ESA) M-class mission, with participation from NASA, to study the geometry and nature of the dark universe. It consists of a 1.2m telescope with two instruments operating at optical and near-infrared wavelengths (0.5-2 microns). The mission is optimized for undertaking two measurements sensitive to dark energy - weak gravitational lensing and galaxy clustering. It will also enable unprecedented advances in many other areas of astrophysics through its 15,000 square degree wide area survey. It has a 6 year nominal lifetime, and was launched July 1, 2023. NASA participation in Euclid includes delivery of the near-infrared detectors as well as participation in the design, data analysis and interpretation by US scientists.

NExScI
NASA Exoplanet Science Institute

The NASA Exoplanet Science Institute (NExScI) is a science operations and analysis service organization for NASA Exoplanet Exploration Program projects and the scientists and engineers that use them. NExScI facilitates the timely and successful execution of exoplanet science by providing software infrastructure, science operations, and consulting to NASA Exoplanet Exploration Program projects and their user communities. NExScI is operated by the California Institute of Technology for the National Aeronautics and Space Administration (NASA) and the Jet Propulsion Laboratory (JPL).

Neowise

NEOWISE
Near-Earth Object Wide-field Infrared Survey Explorer

The NEOWISE project was the asteroid-hunting portion of the Wide-field Infrared Survey Explorer (WISE) mission. Funded by NASA's Planetary Science Division, NEOWISE harvested measurements of asteroids and comets from the WISE images and provided a rich archive for searching WISE data for solar system objects. During its primary mission which ended in February 2011, NEOWISE delivered large and rich infrared datasets of minor planets, including more than 34,000 new discoveries. NEOWISE data have also enabled the discovery of the first known Earth Trojan asteroid. After hibernating for over 2 years, NEOWISE survey observations resumed in December 2013 to learn more about the population of near-Earth objects and comets that could pose an impact hazard to the Earth. During its multiyear survey in the 3.4 and 4.6 μm infrared bands, NEOWISE rapidly characterized near-Earth objects (NEOs) and obtained accurate measurements of their diameters and albedos (how much light an object reflects). NEOWISE was equally sensitive to both light-colored asteroids and the optically dark objects that are difficult for ground-based observers to discover and characterize. Survey operations were completed on July 31, 2024. The spacecraft was decommissioned on August 8, 2024, and re-entered the Earth's atmosphere on November 1, 2024.

ZTF
Zwicky Transient Facility

The Zwicky Transient Facility (ZTF) is a new time-domain survey with first light at Palomar Observatory in 2017. Building on the highly successful legacy of the Palomar Transient Factory (PTF), ZTF uses a new camera with a 47 square degree field of view mounted on the Samuel Oschin 48-inch (1.2m) Schmidt telescope. The new camera (16 elements of 6k x 6k CCDs) enables a full scan of the northern visible sky every night. ZTF's extremely wide field and fast readout electronics will enable a survey more than an order of magnitude faster than that of PTF. ZTF will search and catalog rare and exotic transients and its data will drive novel studies of supernovae, variable stars, binaries, AGN, and asteroids.
