Latest News Current NICER launch date: June 1, 2017 (23 May 2017) NICER is currently scheduled for launch to the ISS on SpaceX-11, which is now scheduled for launch on June 1 at 5:55 pm eastern time from the Kennedy Space Center. Backup dates are June 3 (5:04 PM EDT) and 4 (4:44 PM EDT). News Feature: SpaceX Dragon to Deliver Research - including NICER - to the Space Station (22 May 2017) SpaceX is scheduled to launch its Dragon spacecraft for its 11th commercial resupply mission to the International Space Station on June 1 from Kennedy Space Center's historic pad 39A. Dragon will lift into orbit atop the Falcon 9 rocket carrying crew supplies, equipment and scientific research, including the NICER payload, to crew members living aboard the station. Once affixed to the exterior of the space station, NICER will study the physics of neutron stars, providing new insight into their nature and behavior. Planck High-Redshift Source Candidates (PHZ) Catalog (22 May 2017) This catalog of 2,151 Planck high-z source candidates (the PHZ list) that have been detected in the cleanest 26% of the sky, with flux densities at 545 GHz above 500 mJy (from the Planck Collaboration 2016, A&A, 596, A100 is now available in Browse and Xamin. FRIICAT - FIRST Catalog of FR II Radio Galaxies (18 May 2017) This catalog of 123 Fanaroff and Riley class II edge-brightened radio galaxies (FR IIs) with redshifts <= 0.15 that were obtained by combining observations from the NVSS, FIRST, and SDSS surveys (from Capetti et al. 2017, A&A, 601, A81) is now available in Browse and Xamin. Swift Ultraviolet and Optical Telescope (UVOT) Serendipitous Source Catalog, v1.1 (17 May 2017) Version 1.1 of the Swift UVOT SSC listing the optical and UV properties of 13,860,568 source detections made by this telescope (v1.0 is described in Page et al. 2015, Proc. Swift 10 Years of Discovery conference, p. 37) is now available in Browse and Xamin, as is the associated list of 23,059 UVOT observations from the start of Swift operations in 2005 until Oct 1, 2010 in which these sources were found. Second Planck Sunyaev Zel'dovich Source Catalog (PSZ2) (16 May 2017) The all-sky Planck catalog of 1,653 galaxy clusters and cluster candidates (PSZ2) derived from Sunyaev-Zeldovich (SZ) effect detections using the full 29 months of Planck satellite observations - the largest SZ-selected sample of galaxy clusters yet produced and the deepest systematic all-sky survey of galaxy clusters - created by the Planck Collaboration 2016, A&A, 594, A27 is now available in Browse and Xamin.
