Introduction
While planning their live countdown to launch Space Physics and Cosmology (SPHEREx) and Polarimeter to Unify the Corona and Heliosphere (PUNCH) on Monday night, NASA and SpaceX were both held back due to technical and weather challenges. These delays underscore a growing interest among scientists – and enthusiasts – in deep望与探测太空。Both missions aim to unravel mysteries about the universe, offering insights into cosmic phenomena and the structure of space itself.
Space Physics and Cosmology (SPHEREx)
SPHEREx is NASA’s ambitious project, designed to map the entire sky in 102 infrared colors, capturing the baton-like light from vast galaxies. With camerasquito spectroscopy, this mission will dissect the light into wavelengths to study the universe’s chemical makeup and distance from Earth. Striping light into its constituent parts helps astrophysicists understand how the universe began and where life prevails.
The spacecraft will observe more than a hundred million stars, challenging humanity’s understanding of cosmic evolution. By slicing the light with filters, scientists can map the universe’s intricate structure, some regions even deeper than the galactic gas cloud that bois over our home star. This research is pivotal for advancing theories about inflation and cosmic acceleration, when the universe expanded most rapidly this past universe’s growth.
Polarimeter to Unify the Corona and Heliosphere (PUNCH)
PUNCH is mission number 708, prioritizing observations at the Sun’s northern and southern poles. With four satellites collecting in the polar orbit, PUNCH aims to capture the intricate dynamics of solar wind. The satellites will analyze coronagraphs and cameras, using polarized filters to track the movement of solar flare material toward Earth. This mission contributes to understanding the Sun’s wind’ve boundary and its role in galactic structure, enhancing our understanding of the Sun’s role in the cosmic mosaic.
