When a Chinese spy balloon floated across the U.S. in early February, it ignited a firestorm of concern on Capitol Hill and led to the cancellation of Secretary of State Antony Blinken's trip to China amid already fraught relations between the two countries. 

China has maintained it was a weather balloon that veered off course. But the balloon was doing something much more sinister, according to the U.S. 

There have since been a number of other incidents involving flying objects, raising even more concern. 

Here's what we know about the balloon and those other objects:

The Defense Department said it was tracking the balloon over the continental U.S., and that the balloon had been over Montana a day earlier, on Feb. 1. Following the announcement, the balloon stopped loitering and proceeded as fast as it could toward the East Coast, a U.S. official said.

Feb. 4: Balloon shot down

 A U.S. fighter jet shot down the balloon off the coast of South Carolina.

The spy balloon's height was comparable to the Statue of Liberty, about "200 feet tall with a jetliner size payload," Assistant Secretary of Defense Melissa Dalton told senators during a hearing on Feb. 9. 

It had collection pod equipment, including high-tech equipment that could collect communications signals and other sensitive information, and solar panels located on the metal truss suspended below the balloon, according to government officials. It had equipment that was "clearly for intelligence surveillance," including "multiple antennas" that were "likely capable of collecting and geo-locating communications," according to a statement by a senior State Department official

Video of the balloon showed small motors and multiple propellers that allowed China to actively maneuver the balloon over specific locations, according to a senior administration official, and it was steered by rudder, a U.S. official said. 

The balloon's payload weighed more than a couple thousand pounds, according to Gen. Glen VanHerck, commander of North American Aerospace Defense Command and U.S. Northern Command.

Feb. 5: Balloon recovery begins

Recovery of the balloon began. It was delayed by a day after it was shot down because of rough seas off the coast of South Carolina, Dalton said. 

A U.S. official said later that underwater pictures of the debris field show the wreckage remarkably intact given its fall from 60,000 feet. The debris field is about seven miles wide and the debris is in relatively shallow water, at about 47 feet deep, according to a senior military official. 

Navy and FBI dive teams have been involved in the search.

Upon collection of the wreckage, the evidence was rinsed clean of salt water before the FBI forensically examined it, according to senior FBI officials.

The FBI has been evaluating evidence collected from debris field in the Atlantic at the bureau's lab in Quantico, Virginia, senior FBI officials said. The FBI lab has the balloon canopy, wires and other electronic components collected from the water surface. The officials said they have not detected explosive materials on the evidence that has already been examined.

In an interview with CBS News, Defense Secretary Lloyd Austin said that the "majority" of the balloon pieces that were on the surface had been recovered. "We've mapped out the debris field and now we'll go through detailed efforts to recover the debris that's on the ocean floor," Austin said.

The search for debris was suspended because of bad weather. The debris that was not retrieved from the bottom of the ocean had been weighted down to prevent it from being moved by the heavy seas.

Feb. 10 to 12: Three more unidentified objects

Three more objects were spotted over U.S. and Canadian airspace. On Friday, Feb. 10, U.S. officials downed a "high-altitude object" off the coast of Alaska. An unidentified object was shot down in Canadian airspace the next day, and the U.S. military shot down another object spotted over the Great Lakes region that Sunday, Feb. 12.

During a briefing that night, Defense Department officials said the last three objects did not pose a kinetic military threat, but their path and proximity to sensitive Defense Department sites and the altitude they were flying could be a hazard to civilian aviation and thus raised concern.

Dalton said in the briefing with reporters that the U.S has been more closely scrutinizing airspace at certain altitudes, including enhancing the radar. 

The unidentified object that was downed near Alaska was the size of a small car, according to the Pentagon. The object shot down over Lake Huron appeared to be octagonal in shape with strings hanging off, but no discernable payload, a senior administration official said.

Feb. 13: Balloon recovery

Recovery efforts resumed after being postponed because of bad weather. 

A U.S. official said a "significant" portion – 30 to 40 feet – of the balloon's antenna array was recovered from the ocean bottom. These portions will be going to an FBI lab at Quantico, an official said. 

State Department spokesman Ned Price said that the State Department has had communication with its Chinese counterpart because "we believe in keeping lines of communication open." 

Price said the focus remained on recovery efforts. 

More photos were released of what has been recovered so far of the balloon.

Feb. 13: Other unidentified objects

The search for the objects shot down off the coast of Alaska and over Canada is continuing, National Security Council spokesman John Kirby said during a White House briefing, because the remains are located in remote terrain, making them hard to find. He said the object over Lake Huron is in deep water. 

Kirby said that the U.S. did not detect that any of the objects were sending communications signals before they were shot down. The U.S. also assessed that they showed no signs of self-propulsion or maneuvering and were not manned, he said. 

"The likely hypothesis is they were being moved by the prevailing winds," Kirby said. 

Kirby said on MSNBC on Monday that the objects were flying at between 20,000 and 40,000 feet. Most commercial aircraft fly at about 30,000 feet. These objects were also shot down, he said, because they were much smaller than the Chinese balloon.   

No one has claimed ownership of any of them and the U.S., Kirby said, has not yet been able to gain access to the unmanned objects in part because of weather conditions and also because the one shot down Sunday over Lake Huron is underwater. 

There may be "completely benign and totally explainable reasons" for why these objects were flying over North America, but the U.S. won't know whether that's the case until they are retrieved, Kirby said.

Kirby said there is so far no indication that the three unidentified objects were part of Chinas' spying program or involved in "external intelligence collection efforts." The U.S. is also "ruling out that they were U.S. government objects," he said. Though it's still possible they were linked to commercial or research entities. 

"That very well could be or could emerge as a leading explanation here," he told reporters. 

Army Gen. Mark Milley, chairman of the Joint Chiefs of Staff, confirmed that the first missile fired by a U.S. fighter jet at the object over Lake Huron missed its target and landed in the water. The second missile hit the target, he said. 

Milley also revealed more about the search for the three objects, saying none have yet been recovered because they're located in "very difficult terrain" — one in the Arctic Circle off the coast of Alaska, the second in a mountain range in northern Canada and the third is likely a couple hundred feet underwater in Lake Huron. 

"We'll get them eventually but it's going to take some time to recover them," he said. 

And, U.S. officials also said Tuesday that U.S. intelligence tracked the spy balloon that was shot down earlier this month when it lifted off from Hainan Island, off the south coast of China. It drifted east in the direction of Guam and Hawaii and then went north toward Alaska, entering U.S. airspace on Jan. 28. Given the path, it's possible that the balloon was blown off course by weather, but officials said that once it came south over the continental United States, it was being controlled by China.

Feb. 16: Biden speaks about latest objects

President Biden addressed the nation about the spy balloon and unidentified objects for the first time since they were shot down, saying the three most recent incidents are not believed to be part of China's expansive spy balloon program. 

"Nothing right now suggests they were related to China's spy balloon program or that they were surveillance vehicles from any other country," he said. 

Special Report: Biden speaks about Chinese spy balloon and other objects shot down 15:50

Mr. Biden said at the time the three objects were shot down over North America, the U.S. could not rule out the possible surveillance risk to sensitive facilities. But he said the intelligence community's current assessment is that the unidentified objects are "most likely balloons tied to private companies, recreation or research institutions, studying weather or conducting other scientific research." 

The U.S. has apparently been observing more such objects recently because the military enhanced the sensitivity of its radars. 

The Navy ended its recovery operations for the spy balloon's remnants off the coast of South Carolina after retrieving the parts they were looking for.

"Final pieces of debris are being transferred to the Federal Bureau of Investigation Laboratory in Virginia for counterintelligence exploitation, as has occurred with the previous surface and subsurface debris recovered," U.S. Northern Command said in a statement.

The U.S. called off its search for the flying objects that were shot down over Alaska on Feb. 10 and Lake Huron on Feb. 12 after being unable to find any debris, raising the possibility that it may never be known what they were. 

The areas where the devices were shot down were searched using airborne imagery and sensors, surface sensors and inspections, as well as subsurface scans, U.S. Northern Command said. 

Weather conditions and ice instability in near Deadhorse, Alaska, contributed to the decision to end the search at that location, the military said.

June 29: Spy balloon did not collect information over U.S., Pentagon says

After months of analysis on the wreckage of the Chinese spy balloon, Pentagon spokesman Brig. Gen. Patrick Ryder said the U.S. believes it did not collect information while it transited from Alaska to South Carolina. 

"We believe that it did not collect while it was transiting the United States or flying over the United States and certainly the efforts that we made contributed," he said. 

Ryder's comments came in response to a question about reporting that said the balloon contained American-made parts. 

"I don't have any specifics to provide as it pertains to the [People's Republic of China] high-altitude balloon and any potential U.S. components," Ryder said.
