The mission was launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, California.

Aspect	Details
Main Objective	To study the origins of the universe, evolution of galaxies, and life-forming molecules in the Milky Way.
Sky Mapping	SPHEREx will create the most detailed map of the sky ever made using 102 infrared colours.
Galaxy Survey	The mission will observe over 450 million galaxies and measure their 3D positions.
Cosmological Importance	Helps scientists understand the early expansion of the universe and cosmic inflation.

MISSION DRISHTI

Indian spacetech startup GalaxEye is developing Mission Drishti, a satellite mission planned for launch in 2026.

The mission uses OptoSAR technology, combining Synthetic Aperture Radar (SAR) and optical imaging to provide near-real-time, all-weather intelligence for defence and agriculture.

PT Facts

Infrared Spectroscopy: SPHEREx will survey the entire sky using infrared spectroscopy.
Molecule Detection: The mission will help detect water and organic molecules in star and planet-forming regions.
Infrared Astronomy: Useful for studying cold objects, dust-obscured regions, and distant galaxies.
Cosmic Inflation: SPHEREx is important for understanding cosmic inflation and the large-scale structure of the universe.
