Boeing Co. and NASA launched the long-delayed Starliner space capsule for a planned rendezvous with the International Space Station, following two earlier failed attempts for a program that has bedeviled the company and left SpaceX as the only American option for ferrying astronauts.

Boeing Co. and NASA launched the long-delayed Starliner space capsule for a planned rendezvous with the International Space Station, following two earlier failed attempts for a program that has bedeviled the company and left SpaceX as the only American option for ferrying astronauts.

The United Launch Alliance Atlas V rocket launched the craft, without crew, from Kennedy Space Center in Florida at 6:54 p.m. ET Thursday for a day-long cruise to the space station.

The CST-100 Starship is scheduled to arrive about 24 hours later on Friday and plans to test multiple docking technologies that Boeing was unable to perform during a December 2019 flight cut short by software flaws.

Boeing and NASA engineers are exploring why two of the 12 thrusters situated at the aft of the spacecraft failed during a key maneuvering burn, although flight computers quickly switched to other thrusters, NASA’s commercial crew program manager Steve Stich said in a news briefing hours after the launch. The thrust system is also used in early phases of the Starliner’s approach to the space station and when it de-orbits to commence its return to Earth.

“The system is designed to be redundant and worked as designed, and now the team is working on why we had those anomalies occur,” said Mark Nappi, Boeing’s Starliner manager. Engineers may be able to resolve the thruster issues during the flight, Stich said.

A system that removes heat from the spacecraft interior, called a sublimator, also performed “sluggishly” during the ascent and will be probed, Stich said.

The test flight comes at a critical moment for Boeing, which is trying to overcome years of challenges with Starliner’s development. Boeing has tallied $595 million in extraordinary charges to cover Starliner delays, including $185 million last October. Moreover, Chief Executive Officer Dave Calhoun is under fire from customers and investors as Boeing struggles to meet deadlines and technical standards across its product lineup.

“We wouldn’t be here right now if we weren’t confident this would be a successful mission,” astronaut Butch Wilmore said Wednesday during a prelaunch news briefing with NASA officials. Wilmore was joined by astronauts Sunita Williams and Mark Fincke; the three have been working with Boeing on the development, and each is hoping to be selected for a future Starliner flight.

Second Transport

NASA is keen to gain a second transport option for its commercial crew program, a goal set eight years ago with contract awards to Boeing and Elon Musk’s Space Exploration Technologies Corp. to build and operate vehicles to fly astronauts to and from the space station. SpaceX has flown four astronaut rotations to the ISS, with its last launch on April 27 and the fifth planned for September.

Getting the vessel aloft has been just one of multiple challenges confronting Boeing, including delays in delivering its flagship wide-body commercial aircraft, the 787, and parts shortages that have slowed output of the best-selling 737 Max. Boeing is also involved with the ongoing work to ready a separate NASA project, the massive SLS rocket for moon missions, for a launch after years of delays and cost overruns.

If the flight test doesn’t uncover any additional large issues, the plan is to have the program ready for a flight test with astronauts by the end of 2022. Starliner’s regular ISS crew rotations would then begin in 2023, barring further glitches.

The last Starliner launch attempt, in August, was scrubbed after multiple valves on the propulsion system used in space became unresponsive shortly before the planned flight. That prompted extensive testing and led engineers to better seal the valves and prevent moisture seepage, which was believed to have contributed to a chemical reaction that prevented their operation.

The prior 2019 attempt, in which the Starliner spent 48 hours in orbit, was marred by what a NASA review panel later deemed two “critical software defects.” The Starliner suffered a problem with its mission timing software shortly after reaching space, with the craft showing an elapsed time 11 hours different from the actual mission time. That caused it to fire multiple thrusters too early, burning too much propellant to allow for the craft to continue to the space station. Five months later, Boeing said it wanted to perform a second uncrewed demonstration flight.

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
