Two men with SpaceX descended on a Saskatchewan farm in a moving truck Tuesday to retrieve cosmic junk that fell earlier this year from one of its spacecrafts.

The workers, who didn含羞草研究社檛 give their names while at the farm near Ituna, lugged the large scorched pieces of carbon fibre and aluminum into the back of the U-Haul before leaving.

They declined to say why the fragments failed to burn up before slamming into the field, what spacecraft the pieces came from, where the wreckage was going and what the company plans to do with it.

They confirmed they work for SpaceX, founded by entrepreneur Elon Musk, and directed further questions to a company email. SpaceX did not immediately respond to a request for comment Tuesday.

The retrieval comes months after farmer Barry Sawchuk found the debris and said he was contacted by SpaceX for its return.

One fragment, taller than Sawchuk, weighs 44 kilograms. A second, smaller one is about 10 kilograms. Other pieces were also found on neighbouring farms.

Sawchuk said SpaceX paid him an undisclosed amount of money to get the junk back, and he plans to use those dollars to help fund a new rink in the community northeast of Regina.

He said having the men show up Tuesday felt like any other day.

含羞草研究社淚t含羞草研究社檚 no different than going to seed a crop or harvesting a good crop. It含羞草研究社檚 all just the same thing,含羞草研究社� Sawchuk told reporters.

含羞草研究社淚 guess the one thing is it含羞草研究社檚 a little community that is on the map. Let含羞草研究社檚 hope it doesn含羞草研究社檛 happen again and somebody doesn含羞草研究社檛 get hurt.含羞草研究社�

Sawchuk, who briefly spoke with the SpaceX staff, said they told him the company wants to figure out why the debris didn含羞草研究社檛 dissolve in the atmosphere.

含羞草研究社淭hey realized there was an issue, so they含羞草研究社檙e trying to deal with it,含羞草研究社� he said.

Samantha Lawler, an astronomy professor at the University of Regina who was at the farm to witness the retrieval, said she wanted to learn why the space junk didn含羞草研究社檛 burn up.

She said the company has thousands of Starlink satellites in orbit that are expected to re-enter Earth in batches over the next few years. There will be problems if they hit the ground, she said.

含羞草研究社淚f those re-entries make it to the ground in hundred-pound pieces of garbage, like we just saw, that (could) kill lots of people. It含羞草研究社檚 terrifying.含羞草研究社�

Lawler added she wasn含羞草研究社檛 surprised the SpaceX workers didn含羞草研究社檛 share more details.

含羞草研究社淪paceX is so notorious for not responding to journalists, ever,含羞草研究社� she said.

Lawler previously sent photos and information about Sawchuk含羞草研究社檚 debris to Jonathan McDowell, an astrophysicist at Harvard who tracks space launches.

Looking at data, McDowell determined the farmer含羞草研究社檚 find was likely linked to a SpaceX Dragon spacecraft that returned to Earth with four passengers from the International Space Station in February.

Debris has also been found in other locations in the United States and Australia.
