Kuala Lumpur , Malaysia ( CNN ) -- Raw satellite data about missing Malaysia Airlines Flight 370 will be released Tuesday , a Malaysian official said Monday . Malaysian acting Transport Minister Hishammuddin Hussein made the comments about the data from satellite company Inmarsat as he toured a newly constructed terminal at Kuala Lumpur International Airport . Families of the passengers on board the plane , which disappeared in March over Southeast Asia while carrying 239 people , have been demanding that the raw data be made public . The fate of the plane and those on board has become one of the great aviation mysteries of modern times . Inmarsat , the company whose satellites communicated with the missing plane in its last hours , had said it did n't have the authority to release the data . But last week , Inmarsat and Malaysian authorities said they were trying to make the raw data accessible . `` In line with our commitment towards greater transparency , all parties are working for the release of the data communication logs and the technical description of the analysis for public consumption , '' Inmarsat and the Malaysian aviation officials said in a joint statement . Publication of the raw satellite data could allow for independent analysis of what happened on March 8 , the day the Boeing 777 veered sharply off its planned route from Kuala Lumpur to Beijing and dropped off radar screens . Analysts have said the data could help discount some theories about what happened to the jetliner , and potentially fuel new ones . Malaysia and Australia , the two countries at the forefront of the search , have said that an analysis by international experts of all the available information -- including the satellite data -- leads them to conclude that the plane ended up in the southern Indian Ocean . But months of searching above and below the surface of the ocean has so far failed to find any physical trace of the missing passenger jet . CNN 's Saima Mohsin and Mitra Mobasherat reported from Kuala Lumpur , and Jethro Mullen reported and wrote from Hong Kong .
Malaysian acting transport minister says the Inmarsat data will be made public . Families of passengers on the missing flight have called for its release . No physical trace has been found of the passenger jet or the people it was carrying .
