NASA has provided an update on the ambitious SPHEREx mission, which will launch in the coming years and map the entire sky from low-Earth orbit.

The spacecraft known as SPHEREx, which stands for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, is assembling in a clean room at NASA’s Jet Propulsion Laboratory in Southern California. Its unique cone form is already evident to all.

Two more little cones are tucked inside the larger one. These encircle SPHEREx’s telescope to shield it from the sun’s and Earth’s heat while it is in orbit.

As the spacecraft must move somewhat quickly when scanning the sky, SPHEREx needs to be extremely nimble, according to a Thursday update from JPL’s Sara Susca, deputy payload manager and payload systems engineer for the project. Although it doesn’t appear so, the shields are really comprised of layers of material, much like a sandwich, and are fairly light. Aluminium sheets cover the exterior, while an aluminium honeycomb structure within resembles cardboard and is both light and strong.

The crucial telescope on board the spaceship, made by Boulder, Colorado-based Ball Aerospace, will use three mirrors and six detectors to gather infrared light from far-off objects.

The massive database containing galaxies, stars, nebulae, and other celestial objects will be created over the course of two years by the SPHEREx telescope mapping the sky four times.

The mission’s goal is to aid scientists in better comprehending the origins of water and other essential elements required for life. In order to achieve this, the mission will measure the amount of water ice present in interstellar clouds, which are clouds of gas and dust where planets are eventually formed and new stars are formed.

In order to understand more about the formation and evolution of galaxies, the SPHEREx team will also be able to investigate their cosmic past.

Not to mention, SPHEREx’s map of millions of galaxies will allow scientists to attempt and learn more about how the cosmos expanded quickly just seconds after the Big Bang.

SpaceX will launch the spacecraft from Vandenberg Space Force Base in California no later than April 2025, according to a 2019 NASA confirmation of the SPHEREx mission.
