We discuss the status of the MAXIMA and MAXIPOL cosmic microwave background balloon-borne experiments. The MAXIMA and MAXIPOL instruments consist of a 1.3 m off-axis Gregorian telescope and a receiver housing a 16 element array of 100 mK bolometers. Observations are made in 3 frequency bands centered on 150, 240, and 410 GHz. We recently released temperature anisotropy power spectrum results (l=36 to l=785) from the August 1998 MAXIMA-1 flight. During the second MAXIMA flight, launched in June 1999 (MAXIMA-2), we scanned 225 square degrees of CMB sky with extremely low galactic dust contamination. Approximately 50 square degrees of this region overlaps the MAXIMA-1 observations. MAXIMA-2 data analysis is currently in progress. MAXIPOL will attempt detection of the CMB polarization anisotropy. The instrument is based on the MAXIMA receiver which has the highest sensitivity of any CMB receiver to date. Instrument preparation is in progress and a 36 hour flight is planned for 2001. MAXIMA is supported by NASA though grants NAG5-4454 and NAG5-3941, and by the Center for Particle Astrophyiscs, a National Science and Technology Center operated by the University of California, Berkeley, under Cooperative Agreement No. AST 9120005. MAXIPOL is supported by NASA through grants NAG5-9349 and NAG5-9398.
