Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

NAME VISIBLE CAMERA
TYPE IMAGER
DESCRIPTION Instrument Overview =================== The LCROSS visible camera (VIS) is a ruggedized NTSC color video camera from the RocketCam(TM) camera family developed by Ecliptic Enterprises, Inc. The unit consists of a camera module and a lens. The camera's focal plane CCD sensor is 752 [H] x 582 [V] pixel format, operating at 30 Hz (60 Fields/Sec). The flight unit's lens is a 12 mm (focal length), f/1.2 lens providing a 30.1 deg [H] x 22.8 deg [V] (37.6 deg [Diagonal]) field-of-view. Interlaced NTSC fields are sampled by the Data Handling Unit (DHU) at 720 x 243 resolution resulting in a final image resolution of 720 x 486 pixels. Each pixel is 24-bit RGB with 8 bits per color channel. These images are compressed using a lossy compression algorithm performed by the Analog Devices 611 Video Codec set on 80% quality and decompressed on the ground. The visible camera's peak power during operation is 2.9 W. The VIS camera has been fixed to an auto-gain/white balance setting. Scientific Objectives ===================== The VIS camera provides context imagery to support interpretation of data collected by the other LCROSS instruments. Calibration =========== There are no calibration files associated with this instrument. Operational Modes ================= The VIS camera has one operational mode: auto-gain and white balance enabled. The DHU can vary the rate at which images are downlinked by discarding images from the 30 images/sec input stream, and several different frame rates are used at different points in the mission.
