Boeing Faces Huge Test With the Launch of Starliner – IndustryWeek

Published

 on


NASA’s effort to resume flying American astronauts on American spacecraft—something that hasn’t happened since the Space Shuttle program ended in 2011—faces a major test this weekend.

Over the past decade, a lot of attention has been paid to billionaire space entrepreneurs like Elon Musk. His company, SpaceX, has been launching payloads into low Earth orbit for years, replete with balletic booster landings and even a space going Tesla Roadster.

But as far as humans are concerned, the U.S. has been dependent on its chief geopolitical rival—Russia—to provide billions of dollars worth of taxi rides to the International Space Station.

That arrangement could end soon if a test launch at Cape Canaveral, Florida, goes as planned on Friday morning. That’s when Boeing Co. hopes to fly its new spacecraft on an initial voyage to the ISS—a mission that could set the stage for human flight in 2020. (SpaceX, which will also perform manned missions for NASA, completed a successful test flight of its new Crew Dragon ship in March.)

The Boeing CST-100 Starliner, scheduled to lift off at 6:36 a.m., sits atop an Atlas V rocket built by United Launch Alliance, a joint venture of Boeing and Lockheed. It’s expected to dock with the ISS about 25 hours later and return early on Dec. 28 with a predawn landing at White Sands Missile Range in New Mexico. Though flying unmanned this time, it can carry as many as seven passengers—four more than  the Apollo 11 spacecraft that headed to the moon 50 years ago.

In 2014, the National Aeronautics and Space Administration awarded SpaceX and Boeing contracts worth a combined $6.8 billion to fly U.S. astronauts to the space station. Since then, both companies have suffered delays that have put the commercial crew program more than two years behind schedule. 

“For us to fly crew, we have to fly crew safely,” Kathy Lueders, NASA’s manager for the commercial crew program, said Tuesday at a news conference. “It doesn’t make any sense for us to do it in a way that we’re not going to be comfortable.”

NASA has declined to set dates on manned missions, pending the outcome of test flights such as the one set for Friday. For Boeing, a successful mission will bring some rare good news; the embattled company has been under fire since 2018 over its now-halted 737 Max program. Two of the commercial planes crashed, killing 346 people. 

Tomorrow’s flight of the Starliner includes 595 pounds (270 kilograms) of cargo for the ISS crew—food, clothing, radiation-detection equipment and a few holiday presents, NASA officials said.

Also aboard will be a test mannequin named Rosie—wearing a red polka dot bandana—in a nod to Rosie the Riveter, the iconic representation of women who built B-17 heavy bombers during World War II. The device will record data on the type of forces and conditions astronauts can expect while riding the Starliner.

On its flight of the Crew Dragon, SpaceX carried Ripley, an anthropomorphic test device outfitted with sensors, named in honor of Sigourney Weaver’s character in the film “Alien.” 

Still, because of the scheduling uncertainties, NASA has begun talks with the Russian space agency about procuring two additional seats on Soyuz missions in fall 2020 and spring 2021, according to Joel Montalbano, deputy manager of the space station program.

And even if NASA begins manned missions next year, the U.S. has said astronauts from both countries will still fly on Soyuz, Crew Dragon and Starliner spacecraft, depending on ISS crew needs and which vehicle is set to launch.

Meanwhile, NASA’s inspector general last month reported that the agency is paying Boeing an average of $90 million per seat to fly astronauts, compared with only $55 million for SpaceX. The report also disclosed that NASA had paid Boeing, a major government defense contractor, an additional $287.2 million to adjust future launch schedules caused by delays in the commercial crew program.

Boeing rejected the report’s conclusion on the $90 million seat price, but didn’t offer an alternative cost figure. While Musk took to Twitter last month to voice his outrage, SpaceX hasn’t responded to a request for comment.

Manufacturing is key to securing America’s future, and with Industry 4.0  in full swing, US companies need to act quickly adopt automation and robotics to remain competitive. Advanced Robotics for Manufacturing (ARM)  seeks to ease this burden by identifying the most critical technology and workforce problems and issuing project calls to its base of 200+ member organizations to catalyze solutions for American manufacturers.

ARM recently announce four new projects from its fifth Technology Project Call that took place earlier in 2019. This increases ARM’s selected projects to 49, and now involves 44% of its 220 member organizations. Pending final negotiations, ARM plans to provide over $1.6 million in funding for a total investment of approximately $5.3 million across the four projects.

These projects will strengthen US manufacturing and are in line with the technology investment plan approved by members. “These projects epitomize the strength of the ARM consortium, bringing together diverse organizations to improve manufacturing processes and lower the barriers to adopting robotics,” noted ARM CTO Arnold Kravitz, “These projects help to ease issues inhibiting growth in US manufacturing, while elevating the human roles.”

Nasa's Hubble marks 34th anniversary with stunning view of Little Dumbbell Nebula – The Times of India

Published

 on


In celebration of its 34th anniversary, Nasa‘s Hubble Space Telescope has once again wowed astronomers and space enthusiasts alike by capturing an extraordinary image of the Little Dumbbell Nebula. This latest image offers a vivid glimpse into the complexities of a planetary nebula, demonstrating Hubble’s enduring capabilities in its extended mission.
The Little Dumbbell Nebula, also known as Messier 76, is one of the faintest objects in the Messier catalog and has intrigued astronomers for its intricate structure and dual-lobed shape. This planetary nebula, located approximately 2,500 light-years away in the constellation Perseus, represents a brief stage in the life cycle of a moderate-sized star like our sun.
Dr. Jennifer Wiseman, a senior scientist at Nasa’s Goddard Space Flight Center, expressed her admiration for the new imagery: “This beautiful nebula is what remains after a star like our own sun has exhausted the bulk of its nuclear fuel and shed its outer layers. The vibrant colors and intricate structures visible in the nebula are a telescope’s way of painting the portrait of the final stages of stellar evolution.”
The Little Dumbbell Nebula, despite its faintness, shines brightly in the detailed images provided by Hubble, allowing scientists to study aspects of the nebula that are rarely visible. The images highlight the dense, glowing gas and complex layers of material expelled from the dying star at the center of the nebula.
According to Dr. Wiseman, “Hubble’s high-resolution capabilities allow us to examine the fine details within the nebula, helping us understand how stars expel their material and the dynamics of this expulsion process. This image is more than just a picture; it’s a deep dive into the life of stars.”
Since its launch on April 24, 1990, Hubble has revolutionized our understanding of the universe, from the dynamics of galaxies to the atmospheres of exoplanets and the distribution of dark matter. Its contributions continue to support and complement data gathered by newer space observatories.
As Hubble continues its journey in space, the scientific community remains enthusiastic about the ongoing contributions it will bring to our understanding of the cosmos. Dr. Wiseman remarked, “Every image from Hubble is a new lesson in our cosmic curriculum.”
These observations not only contribute significantly to our knowledge of the life cycle of stars but also continue to highlight the critical role of Hubble in the exploration and understanding of our universe. As Hubble enters another year in orbit, its legacy of discoveries promises to keep inspiring both the scientific community and the public.

SpaceX sent up the 30th launch from the Space Coast for the year on the evening of April 23, a mission that also featured the company’s 300th successful booster recovery.

A Falcon 9 rocket carrying 23 of SpaceX’s Starlink internet satellites blasted off at 6:17 p.m. Eastern time from Cape Canaveral Space Force Station’s Space Launch Complex 40.

The first-stage booster set a milestone of the 300th time a Falcon 9 or Falcon Heavy booster made a successful recovery landing, and the 270th time SpaceX has reflown a booster.

This particular booster made its ninth trip to space, a resume that includes one human spaceflight, Crew-6. It made its latest recovery landing downrange on the droneship Just Read the Instructions in the Atlantic Ocean.

The company’s first successful booster recovery came in December 2015, and it has not had a failed booster landing since February 2021.

The current record holder for flights flew 11 days ago making its 20th trip off the .

SpaceX has been responsible for all but two of the launches this year from either Kennedy Space Center or Cape Canaveral with United Launch Alliance having launched the other two.

SpaceX could knock out more launches before the end of the month, putting the Space Coast on pace to hit more than 90 by the end of the year, but the rate of launches by SpaceX is also set to pick up for the remainder of the year with some turnaround times at the Cape’s SLC-40 coming in less than three days.

That could amp up frequency so the Space Coast could surpass 100 launches before the end of the year, with the majority coming from SpaceX. It hosted 72 launches in 2023.

More launches from ULA are on tap as well, though, including the May 6 launch atop an Atlas V rocket of the Boeing CST-100 Starliner with a pair of NASA astronauts to the International Space Station.

ULA is also preparing for the second launch ever of its new Vulcan Centaur rocket, which recently received its second Blue Origin BE-4 engine and is just waiting on the payload, Sierra Space’s Dream Chaser spacecraft, to make its way to the Space Coast.

Blue Origin has its own it wants to launch this year as well, with New Glenn making its debut as early as September, according to SLD 45’s range manifest.

Wildlife Wednesday: loons are suffering as water clarity diminishes – Canadian Geographic

Published

 on


The common loon, that icon of northern wilderness, is under threat from climate change due to declining water clarity. Published earlier this month in the journal Ecology, a study conducted by biologists from Chapman University and Rensselaer Polytechnic Institute in the U.S. has demonstrated the first clear evidence of an effect of climate change on this species whose distinct call is so tied to the soundscape of Canada’s lakes and wetlands.

Through the course of their research, the scientists found that July rainfall results in reduced July water clarify in loon territories in Northern Wisconsin. In turn, this makes it difficult for adult loons to find and capture their prey — mainly small fish — underwater, meaning they are unable to meet their chicks’ metabolic needs. Undernourished, the chicks face higher mortality rates. The consistent foraging techniques used by loons across their range means this impact is likely echoed wherever they are found — from Alaska to Canada to Iceland.

The researchers used Landsat imagery to find that there has been a 25-year consistent decline in water clarity, and during this period, body weights of adult loon and chicks alike have also declined. With July being the month of most rapid growth in young loons, the study also pinpointed water clarity in July as being the greatest predictor of loon body weight.

One explanation for why heavier rainfall leads to reduced water clarity is the rain might carry dissolved organic matter into lakes from adjacent streams and shoreline areas. Lawn fertilizers, pet waste and septic system leaks may also be to blame.

The researchers, led by Chapman University professor Walter Piper, hope to use these insights to further conservation efforts for this bird Piper describes as both “so beloved and so poorly understood.”
