Boeing's Starliner is 'go' for crucial May 19 launch to the space station – Space.com

Published

 on


Boeing’s Starliner capsule is ready to launch again.

During a flight readiness review Wednesday (May 11), NASA cleared Starliner to launch on Orbital Flight Test-2 (OFT-2), a crucial uncrewed mission to the International Space Station.

The decision keeps the Boeing spacecraft on track to launch on May 19 at 6:54 p.m. EDT (2254 GMT) from Cape Canaveral Space Force Station’s Space Launch Complex 41 in coastal Florida — assuming no weather or technical issues arise.

Should the mission lift off on time, an ISS docking would happen roughly a day later, on May 20. “It’s my birthday, so I’m really looking forward to a great birthday present here next week,” joked Steve Stich, NASA’s Commercial Crew Program manager, of the docking in a teleconference with reporters Wednesday shortly after the review’s conclusion.

A backup launch date is available on May 20 at 6:32 p.m. EDT (2232 GMT), which would still see a birthday event if the timeline is shifted. Stich added, however, that the greater importance is getting Starliner set to carry astronauts.

“The most important step right now is to go fly this orbital flight test,” Stich said.

NASA officials framed the completion of OFT-2 as crucial to launching more crewed missions to the space station in the near future. The agency is seeking to expand the number of astronauts on board the ISS at a time to boost the science potential of the orbiting complex.

Mark Nappi, vice-president and program manager of the Boeing Commercial Crew Program, said his company is “prepared and ready” to assist with NASA’s work; Starliner currently faces no major obstacles in its review items to get set for launch, docking and landing.

“The Boeing team is prepared and ready. The NASA-Boeing partnership is really strong. It’s a reflection of all the hard work that’s been done,” Nappi said during Wednesday’s call.

Starliner’s major task will be to do what the capsule failed to do on the original OFT mission in December 2019: meet up successfully with the ISS to demonstrate new technologies and, overall, showcase a readiness to fly crews to and from space. 

Many of these technologies are connected with a sensor that will be active throughout the rendezvous with the ISS, Emily Nelson, deputy chief flight director at NASA, said during the press conference.

“One of the most important — and really kind of the coolest — sensor that they’ve got on their spacecraft is called VESTA; it looks for the silhouette of the space station,” she said. 

VESTA, short for “Vision-based Electro-optical Sensor Tracking Assembly,” will be assessed for its ability to identify the space station and to dock at the correct (forward) port on the Harmony module.

“We’ll do a couple of demonstrations, once we get close in, where the spacecraft will stop,” Nelson said, emphasizing that the goal is to make sure the spacecraft will halt when commanded to do that. Once that capability is established, “then we’ll press into the final rendezvous and docking.”

Initially Starliner was set for an OFT-2 launch in August 2021. But during normal preflight checks, engineers found that 13 of the 24 oxidizer valves in the capsule’s propulsion system, located in Starliner’s service module, were stuck.

Diagnosing the problem required rolling Starliner and its United Launch Alliance Atlas V rocket off the pad. A few months later, investigators located the probable cause of the valve issue, which came down to a chemistry issue. The nitrogen tetroxide oxidizer reacted with air moisture, creating nitric acid. Then the nitric acid reacted with the aluminum surrounding the valves, resulting in corrosion products creating difficulties with the valves’ function.

Fixing the valve problem required multiple adjustments, involving sealing a potential problem point for moisture in the electrical connectors, purging moisture using nitrogen gas and adding a new “cycling” routine every two to five days to keep the valves running smoothly. Boeing also replaced Starliner’s service module to get ready for the coming flight.

While every human spaceflight program has its own unique issues and challenges, Stich said the Boeing valve problem brought to his mind a situation during the space shuttle program. During the launch of STS-129 on Nov. 14, 2008, flight controllers saw an abnormal hydrogen flow increase in one of the shuttle Endeavour’s main engines.

Addressing this flow control issue, as the problem was later termed, took months; the issue was eventually traced to a cracked valve arising from the stresses of repeated use. The fix was complex and is now framed as a case study of collaborative problem-solving on NASA’s Academy of Program/Project & Engineering Leadership (APPEL) Knowledge Service.

“We had to go off and do a whole bunch of testing, and then put in some new flow control valves to convince ourselves that we were safe to go fly,” Stich recalled of the shuttle situation. Similarly, looking to Starliner, he said the team has spent eight or nine months investigating and addressing the valve issue.

“It’s just what we find in spaceflight. It’s challenging all the time,” he said. “You find things out about the vehicle that you maybe didn’t know. You go address those technically. You go run the right test. You put the right people and the right teams in place. You go solve the problem. And then when you’re ready, which we are, we go fly.”

Kathy Lueders, NASA’s human spaceflight chief, added that in 30 years of being at the agency, “every development was hard” across all five spacecraft with which she was involved. “You just have to recognize it and do the work,” she said, “and spend the time to make sure that you’re you’re buying down the risks and continue to solve your problems and move forward.”

OFT-2 is Starliner’s second attempt at performing an uncrewed test mission to the ISS. The first try in December 2019 had to be cut short after Starliner experienced numerous software glitches that prevented it from reaching the station.

Boeing, which has a NASA contract to fly astronauts to and from the ISS with Starliner, must achieve an uncrewed test flight to the station before astronauts can climb on board. The company hopes that the first crewed flight on the capsule will happen by the end of 2022. (NASA said Wednesday it is still evaluating how many astronauts will fly on that first crewed flight and will make a decision after OFT-2 completes.)

“This is a really critical time for us, as we’re heading into this and getting ready to once again fly,” Lueders said. “We’ve learned a lot from the initial flight of the demonstration, and then getting ready in the campaign up to the attempt last summer. But now the team has really worked through all that they’ve learned so far and is ready to go.”

SpaceX is the other company NASA selected to fly commercial crew missions. SpaceX recently launched its fourth operational astronaut mission, called Crew-4, and including a crewed demonstration flight to the ISS has been running such missions since mid-2020.

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘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.”
