The EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM) is aballoon-borne far-infrared telescope that will survey star formation historyover cosmological time scales to improve our understanding of why the starformation rate declined at redshift z < 2, despite continued clustering of darkmatter. Specifically,EXCLAIM will map the emission of redshifted carbonmonoxide and singly-ionized carbon lines in windows over a redshift range 0 < z< 3.5, following an innovative approach known as intensity mapping. Intensitymapping measures the statistics of brightness fluctuations of cumulative lineemissions instead of detecting individual galaxies, thus enabling a blind,complete census of the emitting gas. To detect this emission unambiguously,EXCLAIM will cross-correlate with a spectroscopic galaxy catalog. The EXCLAIMmission uses a cryogenic design to cool the telescope optics to approximately1.7 K. The telescope features a 90-cm primary mirror to probe spatial scales onthe sky from the linear regime up to shot noise-dominated scales. The telescopeoptical elements couple to six {\mu}-Spec spectrometer modules, operating overa 420-540 GHz frequency band with a spectral resolution of 512 and featuringmicrowave kinetic inductance detectors. A Radio Frequency System-on-Chip(RFSoC) reads out the detectors in the baseline design. The cryogenic telescopeand the sensitive detectors allow EXCLAIM to reach high sensitivity in spectralwindows of low emission in the upper atmosphere. Here, an overview of themission design and development status since the start of the EXCLAIM project inearly 2019 is presented.
