Shortly after Japan’s Hayabusa2 probe returned to Earth, JAXA showed off some of the samples it collected from asteroid Ryugu. Those rocks came from the “A” chamber of the probe’s sample capsule, which means they were collected during the mission’s first touchdown in February 2019. Now, JAXA has released photos showing the contents of the capsule’s “C” chamber, which it opened on December 21st.
We have not yet confirmed the origin of the artificial object (人工物). A projectile was used during the sample collection and it is possible that this is aluminium separated from the sampler horn at that time.
In JAXA’s tweet, it said the agency opened both chambers “B” and “C.” The “B” chamber is empty since it wasn’t used for collection, but the “C” chamber was used to collect samples during Hayabusa2’s second touchdown in July 2019. JAXA fired an explosive into the asteroid before the second touchdown to create a crater and be able to gather samples from deeper underground. Scientists are hoping that the subsurface samples can offer more clues about the solar system’s formation and early period, since they hadn’t been exposed to the hash environment of space.
JAXA says the largest particles in chamber “C” were about a centimeter in size. If you take a look at the photos, the agency marked one of the particles as “人工物” or “artificial object.” It has yet to confirm where that object came from, but JAXA believes it could be “aluminum separated from the sampler horn” when it used an explosive on asteroid Ryugu’s surface.

Seaspan’s plans to consolidate its ship repair business at Vancouver Drydock is running into opposition from its residential neighbours.
Author of the article:
Seaspan Shipbuilding is outgrowing its operations on the North Shore, but the company’s plans to expand its companion Vancouver Drydock is colliding with concerns of the residential neighbourhood that has grown up around the century-old industrial waterfront.
Building new ships for the Canadian Coast Guard and Royal Canadian Navy was absorbing Seaspan’s capacity to repair ships at its main shipyard at the end of Pemberton Avenue, said company spokeswoman Kris Neely.
Neely said the company has been thinking about expanding for awhile, as part of a vision to create a “multi generational business.”
“As part of that, we’re consolidating our repair and maintenance services out of Vancouver Drydock and then being able to focus on shipbuilding efforts at our Vancouver Shipyard.”
Their plan is to push Seaspan’s existing dry dock facilities on the Lower Lonsdale waterfront 40 metres further into Burrard Inlet, then ask the Port of Vancouver to extend its water lot lease 40 metres to the west in order to add three smaller dry docks.
Seaspan submitted an application for a review of the plan to the port in April. That federal authority deemed the application complete on June 21, opening up a public comment period. That included virtual public meetings July 13 and 15, and ends July 30.
Many of the comments from residents of condo towers that face the proposed expansion have expressed opposition to allowing Seaspan’s migration west when it has space to the east of its existing docks that is already within its lease.
It isn’t just a matter of views being blocked by new facilities jutting out in front of condos, said resident Al Parsons. Residents are concerned about the impact of additional noise and pollution, including tug boats operating in the waters in front of Shipyard Commons, the bustling commercial district and public space with its waterfront trail and a playground.
“We knew Seaspan was our neighbour when we moved in,” Parsons said. “What we didn’t know was that they were going to continue to move westward and, I think, impose themselves on the (waterfront) Spirit Trail.
“It has walkers, joggers, cyclists, there’s a playground that was built for kids, which is going to be right beside this expansion.”
Parsons said residents aren’t opposed to the idea of expansion and support an initiative that Seaspan says would create 100 jobs, but don’t like there wasn’t any consultation before the company submitted its application.
And they are pushing back against a possible westward expansion, unless Seaspan proves it cannot expand east within their existing lease.
The City of North Vancouver is working on a response to Seaspan’s proposal, but would like to see the public comment period extended and all resident and business concerns taken into consideration.
“I understand the concerns and share many of them,” Mayor Linda Buchanan said in a statement. “This project will bring more family-supporting jobs to the community, but the quality of life of residents needs to be a priority as well.”
Neely said Seaspan did look at other options for this expansion, but siting the new dry docks on the east side of its operations would block water access to a fabrication shop on the site that builds components for new vessels at Vancouver Shipyards.
However, Parsons argued that the east side is perhaps more inconvenient for Seaspan, which would be free to use the east side of its property for other purposes if it were granted a westward expansion.
“I know the water lot is deemed industrial but, frankly, Seaspan is pushing too hard on this neighbourhood that a lot of people contribute tax dollars to support annually.”
NASA on Friday said it had selected SpaceX to launch a planned voyage to Jupiter’s icy moon Europa, a huge win for Elon Musk’s company as it sets its sights deeper into the solar system.
The Europa Clipper mission will launch in October 2024 on a Falcon Heavy rocket from the Kennedy Space Center in Florida, with the total contract worth $178 million.
The mission was previously supposed to take off on NASA’s own Space Launch System (SLS) rocket, which has been plagued by delays and cost overruns, with critics calling it a “jobs program” for the state of Alabama where much of the development work is taking place.
While SLS isn’t yet operational, Falcon Heavy has deployed on both commercial and government missions since its maiden flight in 2018 when it carried Musk’s own Tesla Roadster into space.
It generates more than five million pounds of thrust (22 million Newtons) at liftoff, equal to approximately eighteen 747 aircraft.
The Europa clipper orbiter will make about 40 to 50 close passes over Europa to determine whether the icy moon could harbor conditions suitable for life.
Its payload will include cameras and spectrometers to produce high-resolution images and compositional maps of the surface and atmosphere, as well as radar to penetrate the ice layer to search for liquid water below.
Since 2016, there have been 350 accidents involving tugboats or barges in B.C., including 24 sinkings and two fatalities, according to data collected by the TSB.

More than 20 boats, including ferries, fishing vessels and tugboats, are expected to take part in a memorial event in the Prince Rupert harbour this month in honour of a tugboat captain who died at sea.
Troy Pearson lost his life on Feb. 11 when the tugboat he was captaining sank in the Gardner Canal en route from Kitimat to Kemano. Also killed was 25-year-old Charley Cragg, a Tsawwassen man who had recently moved to Terrace and was working his first shift on the boat. A third man, 19-year-old Zac Dolan, was rescued after he made it to shore.
The event is being planned for July 31 by Pearson’s widow, Judy Carlick-Pearson, who originally intended to scatter Pearson’s ashes in the harbour a few weeks after his birthday.
“Next thing you know, we had people from the coast guard saying they wanted to be here, as well as guys from the ferries, fishing boats, commercial tugs and the marine union,” she said.
Carlick-Pearson is hoping the event, which will involve the boats forming a wide circle in the harbour while eight bells sound to signal the end of the watch, will bring attention to the continuing investigation into the sinking of the tugboat Ingenika.
On Feb. 10 — a day on which 11 cold temperature records were broken as B.C. was hit by an Arctic outflow — Pearson, Cragg and Dolan boarded the tugboat despite a forecast of 50-knot winds. The boat, which belonged to Wainwright Marine Services, was towing a barge carrying construction supplies for a multi-year Rio Tinto tunnel project at Kemano designed to guarantee a stable supply of hydroelectric power to the company’s Kitimat aluminum smelter.
RCMP Cpl. Madonna Saunderson said that just after midnight on Feb. 11, an emergency beacon was received from a tugboat in the Gardner Canal. The RCMP vessel Inkster was dispatched from Hartley Bay and found a man dead in the water. The coast guard found a second dead man. A third person was rescued after reaching shore.
Reached Friday, Saunderson said the RCMP’s investigation into the tugboat sinking comtinues. The Transportation Safety Board said its investigation is still underway as well, with nothing new to say at this time. Postmedia received a similar reply from both WorkSafeBC and the B.C. Coroners Service.
Many in B.C.’s marine community are hoping the four investigations could lead to improved safety regulations in the tow industry. Since 2016, there have been 350 accidents involving tugboats or barges in B.C., including 24 sinkings and two fatalities, according to data collected by the TSB.
The board has been calling on Transport Canada to make safety management systems (SMS) mandatory on all vessels, including small tugboats like the Ingenika, for almost a decade.
SMS is an internationally recognized framework that allows companies to identify and address safety risks. It can incorporate elements such as safe operating standards, a planned maintenance program, a crew training regime and how to respond to specific emergency situations. Transport Canada already requires SMS for larger vessels.
Other stakeholders, including some B.C. tugboat companies, want to see the tug-to-tow weight ratio regulated.
There are currently no regulations governing the tug-to-tow ratio, which allows small tugs to pull large barges that may be beyond their capabilities, said Jason Woods, president of the International Longshore and Warehouse Union, Local 400.
“You can tow a barge full of logging equipment on a bungee cord if you want to,” he has said.
Transport Canada has indicated it is working on a number of “new regulatory projects” that will apply to all Canadian vessels, including making SMS mandatory, with a first draft expected in the fall.
Meanwhile, Carlick-Pearson, as well as some coastal First Nations communities, are calling on authorities to raise the Ingenika from the bottom of the Gardner Canal both to prevent environmental damage and determine why the tug sank.
“Without the boat, we won’t really know what happened that night,” she said. “It could be a smoking gun.”
Carlick-Pearson has also started raising funds to start a marine training school in Prince Rupert in honour of her husband. She hopes to teach kids and families about safety on the water, as well as offer the courses needed for a career in the marine industry. Pearson had to travel to Ladner to do his training, she said.
“It would be better to have something here, closer to home, particularly for Indigenous people who might not want to leave their community for training.”
