SPHEREx survey progress and early observations
6 July 2026 • 13:20 - 13:40 CEST | Room B4-M3
Abstract
SPHEREx is the all sky near infrared survey launched on March 11 of 2025. We began full sky survey operations on May 1 of 2025 following two months of in orbit commissioning. The mission is designed to map the entire sky in 102 colors from 0.75 to 5 microns four times during the two year planned survey. In this talk I will describe the launch and in orbit commissioning activities. I will then provide an update on the performance of our calibrations and the current observation status. I will also show several examples of the science enabled by the early SPHEREx data release.

Caltech (United States)
Howard Hui is a research scientist at Caltech and an affiliate at NASA JPL. He obtained his PhD in 2018 at Caltech where he built the BICEP3 telescope. BICEP3, together with the other instruments in the BICEP experiment, produced the strongest constraint on primordial gravitational waves from measurements of the polarization of the cosmic microwave background. Since 2019 he has served as the calibration scientist for the NASA SPHEREx mission, an all sky near infrared survey that launched in March 2025. He is responsible for the instrument integration, testing, and calibration for the mission.
