NASA’s upcoming SPHEREx mission is set to launch no later than April 2025, aiming to create a comprehensive map of the universe. Utilizing its state-of-the-art space telescope, SPHEREx will embark on a groundbreaking mission to measure the abundance of water ice in interstellar clouds and study the cosmic history of galaxies.
Unlike regular telescopes, SPHEREx will rely on detecting infrared light, which has longer wavelengths than visible light. This unique feature will allow the telescope to observe objects that are otherwise invisible to traditional telescopes. To ensure the telescope’s optimal performance, it will be equipped with photon shields and a V-groove radiator to maintain its frigid operating temperature.
The SPHEREx telescope is ingeniously tilted on its base, strategically maximizing its view of the sky while remaining protected by the shields. As the telescope collects light from far-flung celestial bodies, filters installed on top of its detectors will perform spectroscopy, analyzing the light’s different wavelengths.
The mission is managed by NASA’s Jet Propulsion Laboratory (JPL), renowned for its impressive portfolio of successful space endeavors. The telescope itself is built by Ball Aerospace, known for their expertise in constructing cutting-edge space instruments.
One of the most exciting aspects of the SPHEREx mission is that the data collected will be processed and archived at IPAC, located at the prestigious California Institute of Technology (Caltech). This means that the wealth of knowledge gained from this mission will be openly accessible to the public, allowing scientists, researchers, and space enthusiasts to delve into the mysteries of the universe.
Overall, NASA’s SPHEREx mission represents a new chapter in our understanding of the cosmos. With its innovative technology and groundbreaking objectives, the mission promises to unveil previously unknown aspects of our universe, enriching our understanding of water ice in interstellar clouds and uncovering the cosmic history of galaxies. As the launch date looms closer, the excitement among astronomers and space enthusiasts continues to grow. Stay tuned for the remarkable insights that await us from the SPHEREx mission.
