Quote: 'Pancam relies heavily on use of the JPL ICER and LOCO compression algorithms to maximize data return within stringent mission downlink limits. All calibration and flight data products will be generated,archived, and released with the NASA Planetary Data System in PDS image format.'
This is a brief HTML description of the LOCO-based method they used for lossless compression:"

news : "December 29, 2003 -- WASHINGTON - Startling new Army statistics show that strife-torn Baghdad - considered the most dangerous city in the world - now has a lower murder rate than New York. The newest numbers, released by the Army's 1st Infantry Division, reveal that over the past three months, murders and other crimes in Baghdad are decreasing dramatically and that in the month of October, there were fewer murders per capita there than the Big Apple, Chicago, Los Angeles and Washington, D.C.

USATODAY.com - NASA docks contractor $45.2 million for Columbia

USATODAY.com - NASA docks contractor $45.2 million for Columbia : NASA penalized the contractor that maintains and operates the space shuttle fleet $45.2 million for its role in the shuttle Columbia accident, according to a letter NASA released Thursday. The United Space Alliance, a partnership of Boeing and Lockheed Martin, had to forfeit the money even though NASA said the contractor did nothing specific to cause the accident. But a letter from a NASA official said the contractor was "an integral member" of the "team that reached flawed conclusions about the relative safety of Columbia and crew before and during the flight." The letter from NASA deputy associate administrator Michael Kostelnik was sent Jan. 7 to United Space Alliance president Michael McCulley, a former astronaut. The contract spells out performance bonuses based on safety, cost-effectiveness and other factors. For Oct. 1, 2002, through March 31, 2003, the alliance was eligible for $81.2 ...
