    SPHEREx will use a spectrophotometer to perform an all-sky survey that will measure near-infrared spectra from 0.75 to 5.0 micrometers. It will employ a single instrument with a single observing mode and no moving parts to map the entire sky (in 96 different color bands, far exceeding the color resolution of previous all-sky maps [4]) four times during its nominal 25-month mission; the crucial ...

    Ten degrees from the Sun, the K-corona is 1000x fainter than the background stars, [11] requiring precise photometric calibration across the individual cameras, to measure and remove the background starfield, galaxy, and related features—which constitute 99.9% of the light incident on the cameras. The camera images are co-aligned to within 0. ...

    Had it been selected for implementation, FINESSE would have launched no earlier than 2022 and lasted at least two years. The other two finalist concepts competing with FINESSE were Arcus (an X-ray space observatory) and SPHEREx (a near-infrared space observatory). In February 2019, it was announced that SPHEREx had been selected. [5]

    Imaging X-ray Polarimetry Explorer, commonly known as IXPE or SMEX-14, is a space observatory with three identical telescopes designed to measure the polarization of cosmic X-rays of black holes, neutron stars, and pulsars. [6] The observatory, which was launched on 9 December 2021, is an international collaboration between NASA and the Italian ...

    Exoplanetary Circumstellar Environments and Disk Explorer (EXCEDE) is a proposed space telescope for NASA's Explorer program to observe circumstellar protoplanetary and debris discs and study planet formation around nearby (within 100 parsecs) stars of spectral classes M to B. [1] Had it been selected for development, it was proposed to launch in 2019.
