Kuala Lumpur, Malaysia (CNN) — China has new satellite images showing a large object floating in the southern Indian Ocean, and will be sending ships to verify, the Malaysian transport minister said Saturday.
The object is 22.5 meters long and 13 meters wide, (74 feet by 43 feet ), Hishammuddin Hussein announced. He told reporters he’d just gotten the information, and China will release more details in the “coming hours.”
China later said the satellite images showing a “suspected floating object” are dated around noon Tuesday.
The search for the missing Malaysian jetliner expanded Saturday as various countries dispatched additional aircraft and ships to scan the choppy waters of the southern Indian Ocean.
At least six search flights were involved Saturday, including two private jets.
Though the two civilian jets did not have radar, their role was crucial, authorities said.
“It is more likely that a pair of eyes are going to identify something floating in the ocean,” Australian Deputy Prime Minister Warren Truss said.
The first two planes to sweep the southern Indian Ocean on Saturday found no wreckage or debris, its pilots said.
Malaysia Airlines Flight 370 vanished on March 8 with 239 people aboard destined for Beijing from Kuala Lumpur.
Intensified, expanded search
The search area expanded by 50% on Saturday.
“Operations continue, and today they plan to search an area of approximately 10,500 square nautical miles,” he said Saturday.
In addition to two Chinese planes that arrived in Australia, Beijing is sending two more ships to join five already in the southern corridor.
“Two Indian aircraft, a P-8 Poseidon and a C-130 Hercules, arrived in Malaysia last night to assist with the search,” he said.
Seven countries — China, India, Pakistan, Myanmar, Laos, Kyrgyzstan and Kazakhstan — informed investigators that based on preliminary information, their nations had no radar sightings of missing jetliner.
Clues, but no proof
An exhaustive search covering 2.97 million square miles — nearly the size of the continental United States — has yielded some clues, but no proof of where the Boeing 777 is or what happened to it.
The latest, most notable lead revolved around two large objects detected by satellite Sunday floating on waters over 1,400 miles off Australia’s west coast.
“The fact that it’s six days ago that this imagery was captured does mean that clearly what objects were there, are likely to have moved a significant different distance as a result of currents and winds,” Truss said.
“It’s also possible that they’ve just drifted to the bottom of the ocean bed, and the ocean in this area is between 3 and 5 kilometers deep. So it’s a very, very deep part of the ocean, very remote. And all that makes it particularly difficult.”
Debris is a common sight in the waters in that part of the ocean, he said, and includes containers that fall off ships.
Australian Prime Minister Tony Abbott on Friday defended the decision to announce the find, saying Australia owes it to families of those missing “to give them information as soon as it’s to hand.”
But he didn’t make any promises.
“It could just be a container that has fallen off a ship,” Abbott said during a visit to Papua New Guinea. “We just don’t know.”
Malaysia’s interim transportation minister tried to reset expectations for a quick resolution to the mystery after the satellite discovery.
“This is going to be a long haul,” Hishammuddin Hussein said.
U.S. Defense Secretary Chuck Hagel ordered the Navy and policy experts to look at the availability and usefulness of U.S. military undersea technology to try to find the plane’s wreckage and its data recorders, a U.S. military official said.
The United States, which has had a P-8 aircraft working out of Perth, Australia, and Navy ships involved in the search, has spent $2.5 million so far on the entire effort, Pentagon spokesman Col. Steven Warren said Friday.
NASA Administrator Charles Bolden said Friday that the U.S. space agency will mine its existing satellite data and try to capture fresh images that might aid in the search. Its satellites can detect objects as small as 30 feet (98 meters).
Countries from central Asia to Australia are also engaged in the search along an arc drawn by authorities based on satellite pings received from the plane hours after it vanished. One arc tracks the southern Indian Ocean zone that’s the focus of current attention.
“We intend to continue the search until we are absolutely satisfied that further searching would be futile, and that day is not in sight,” the deputy prime minister said. “We will continue the effort, we’ll continue to liaise with our international allies in this search.”
The other tracks over parts of Cambodia, Laos, China and into Kazakhstan.
Malaysian authorities were awaiting permission from Kazakhstan’s government to use the country as a staging area for the northern corridor search, Hishammuddin said.
Malaysia Airlines CEO Ahmad Jauhari Yahya told reporters Saturday that a transcript obtained by The Telegraph newspaper is “inaccurate,” but did not provide additional details.
The Telegraph reported Friday it had a transcript documenting 54 minutes of back-and-forth between the cockpit and ground control from taxiing in Kuala Lumpur to the final message of “All right, good night.”
The alleged transcript reported by the Telegraph contains seemingly routine conversations about which runway to use and what altitude to fly at.
One unexplained element, according to the British newspaper, is a call, in which someone in the cockpit stated that the aircraft was at a cruising altitude of 35,000 feet — something that had been done just six minutes earlier. Twelve minutes after that comes the “good night” message, at around the time Flight 370 was being transferred to Vietnam’s control.
Another wrinkle: Malaysia Airlines chief executive officer Ahmad Jauhari Yahya said the plane was carrying a cargo of lithium-ion batteries, although he didn’t specify the volume of the shipment.
Lithium-ion batteries are commonly used in laptops and cell phones, and have been known to explode, although that occurs rarely.
They were implicated in the fatal crash of a UPS cargo plane in Dubai in 2010, and lithium-ion batteries used to power components on Boeing 787s were blamed for fires in those planes.
There’s no evidence the batteries played a role in the plane’s disappearance, and Ahmad said they are routine cargo aboard aircraft.
“They are not declared dangerous goods” he said, adding that they were “some small batteries, not big batteries.”
Malaysian authorities say they believe the missing plane was deliberately flown off course on its scheduled flight from Kuala Lumpur to Beijing.
