Washington (AFP) - America's first crewed spaceship to achieve orbit since the Space Shuttle era splashed down safely in the Gulf of Mexico on Sunday.

The SpaceX Crew Dragon Endeavour's four main parachutes gently floated down after the vessel landed off the coast of Pensacola at 2:48 pm (1848 GMT).

Pilot Doug Hurley, one of the two astronauts on board, said: "It's truly our honor and privilege" as radio communications became choppy and cut out.

A recovery boat speeded to collect Hurley and commander Bob Behnken, who spent two months on board the International Space Station.

The successful mission demonstrated that the United States once again has the capacity to send its astronauts to space and bring them back.

President Donald Trump -- who had travelled to Florida for the capsule's launch two months ago -- hailed its safe return.

"Thank you to all!" he tweeted. "Great to have NASA Astronauts return to Earth after very successful two month mission."

The United States has had to rely on Russia for this purpose since the last Space Shuttle flew in 2011.

Tropical Storm Isaias, which had scuppered Endeavour's original landing site in the Atlantic, was nearing Florida's east coast Sunday morning, hundreds of miles away.

The mission is also a major win for Elon Musk's SpaceX, which was founded in only 2002 but has leap-frogged its way past Boeing, its main competitor in the commercial space race.

The US has paid the two companies a total of about $7 billion for their "space taxi" contracts, though aerospace giant Boeing's efforts have badly floundered.

Atmospheric re-entry

The Crew Dragon capsule performed several precise procedures in order to return home safely.

At 1:51 pm (1751 GMT), it jettisoned its "trunk" that contains its power, heat and other systems, which will re-enter the Earth's atmosphere and burn up.

Endeavour then fired its thrusters to maneuver itself into the proper orbit and trajectory for splashdown.

At 2:32 pm (1832 GMT) re-entered the atmosphere at a speed of around 17,500 mph (28,000 kph).

The ship's heat shield needed to withstand temperatures of 3,500 degrees Fahrenheit (1900 degrees Celsius), which caused a communications blackout for a few minutes.

Endeavour then deployed two sets of parachutes on its descent, bringing its speed down to a mere 15 mph (24 kph) as it hits the water.

Over the next few minutes, two astronauts will be brought on board a recovery ship for a medical checkup before being taken ashore.

Astro dads

The SpaceX Crew Dragon spacecraft set off from the ISS Saturday evening.

Footage showed the capsule drifting slowly away from the ISS in the darkness of space, ending a two month stay for the crewmates.

During a farewell ceremony on the station, Behnken said that "the hardest part was getting us launched. But the most important part is bringing us home."

Addressing his son and Hurley's son, he held up a toy dinosaur that the children chose to send on the mission and said: "Tremor The Apatosaurus is headed home soon and he'll be with your dads."

Behnken and Hurley's return marks only the beginning for the Crew Dragon as SpaceX and NASA look ahead to future missions.

Endeavor will be brought back to the SpaceX Dragon Lair in Florida where it will undergo a six-weeks-long inspection process, as teams pore over its data and performance in order to certify the vessel as worthy of future low-Earth orbit missions.

The next mission -- dubbed "Crew-1" -- will involve a four member team: commander Michael Hopkins, pilot Victor Glover, and mission specialist Shannon Walker of NASA, along with Japan Aerospace Exploration Agency mission specialist Soichi Noguchi.

Take-off is set for late September and the crew are due to spend six months on the space station.

Boeing to cut staff, plane output after big Q1 loss

New York (AFP) - Boeing announced sweeping cost-cutting measures Wednesday after reporting a first-quarter loss of $641 million following the hit to the airline business from the coronavirus pandemic.

The aerospace giant plans to reduce its workforce by 10 percent through a combination of voluntary and involuntary layoffs and will slash production of its main commercial planes, including the 787 and 777, Chief Executive David Calhoun said in a message to employees that accompanied an earnings release.

"The aviation industry will take years to return to the levels of traffic we saw just a few months ago," Calhoun said. "We have to prepare for that."

Calhoun said the job cuts would be deeper -- more than 15 percent -- in commercial airplanes and services, as compared with defense and space systems, where the business has been more stable.

The quarterly loss of $641 million compared to profits of $2.1 billion in the year-ago period. Revenues fell 26.2 percent to $16.9 billion.

Total debt at the end of the quarter was $38.9 billion, up from $27.3 billion at the end of December.

Calhoun said the belt-tightening was needed to maintain adequate liquidity at a time its revenues are depressed, adding that the company is "exploring potential government funding options" in the wake of COVID-19.

Boeing has previously called for $60 billion in government support for the US aerospace industry. Federal relief legislation includes $17 billion aimed at Boeing. Calhoun has previously balked at the idea of the US taking a stake in Boeing.

The loss reflected "abnormal production costs" connected to the temporary suspension of Puget Sound manufacturing operations due to COVID-19 and due to the suspension of production of the 737 MAX, which remains grounded following two deadly crashes.

Boeing said the pandemic crisis has hit demand for new planes and services, with airlines delaying purchases of jets, slowing delivery schedules and deferring elective maintenance.

It will cut production of the 787 from 14 per month to 10 per month in 2020 and gradually to seven per month by 2022.

Boeing also will trim output on the 777 and lower its targets for the 737 MAX.

"We have done a tremendous job of increasing our production rates and services offerings in recent years," Calhoun said. "But the sharp reduction in our demand for our products and services over the next several years simply won't support the higher levels of output."

Boeing shares jumped 4.1 percent to $136.36 in pre-market trading.

Boeing's new 777X airliner takes off on first flight

Everett (United States) (AFP) - Boeing's new long-haul 777X airliner made its first flight on Saturday, a step forward for the company whose broader prospects remain clouded by the 737 MAX crisis.

The plane took off from a rain-slicked runway a few minutes after 10:00 am local time (1800 GMT), at Paine Field in Everett, Washington, home to Boeing's manufacturing site in the northwestern United States.

Weather conditions had already twice delayed the inaugural takeoff of the plane, which sports blue and white company colors and is emblazoned with the Boeing name.

High winds led to its postponement on Friday, and the company blamed weather for an earlier delay on Thursday, which was rainy.

"Yes!" shouted Boeing spokesman Josh Green as the plane's wheels finally lifted off the tarmac as its two powerful engines sent up huge clouds of mist.

Minutes earlier, the pilots had deployed the plane's winglets -- folding wing tips -- designed to improve the craft's fuel efficiency and make it possible for the plane, with the widest wing span ever from Boeing, to be accommodated at more airports.

The 777X quickly disappeared into the clouds; after a flight lasting several hours, it was to land later at Boeing Field in a Seattle suburb, some 30 miles (50 kilometers) to the south.

The 777X was originally to take to the skies for the first time in mid-2019, but that was postponed due to problems with the new engine, manufactured by General Electric, and difficulties with the wings and software.

Saturday's flight was to be the first of a series of in-flight tests. If they go well, Boeing will officially file for approval from the Federal Aviation Administration (FAA).

With Boeing facing a crisis over its top-selling 737 MAX following two deadly crashes, the 777X is supposed to compete in the long-haul aircraft market with the A350 made by rival European aircraft manufacturer Airbus.

Major airlines including Emirates, Lufthansa, Cathay Pacific, Singapore Airlines and Qatar Airways have placed some 340 orders for the 777X.

The first deliveries of the new model, with maximum capacities of 384 to 426 passengers depending on the configuration, are not expected before early 2021, instead of mid-2020 as initially planned.

The aircraft encountered significant problems during pressurization tests in September.

Business down

Boeing's business has also been weakened by a lack of firm orders from Chinese airlines for its 787 Dreamliner, which is expected to see production cuts.

The 777X has a range of 16,200 to 13,500 kilometers depending on its configuration and the number of passengers aboard, according to the Boeing website. It is also extremely fuel-efficient, an important consideration at a time when passengers are increasingly concerned about carbon emissions.

Its list price is between $410 million to $442 million, though customers often negotiate discounts.

US air safety regulators could clear the 737 MAX to return to service before mid-year, a person close to the process said Friday.

The plane has been grounded since March following two deadly crashes, in Ethiopia and Indonesia. On Tuesday, Boeing announced that it did not expect to win regulatory approval until mid-2020.

Boeing suspended production of the MAX this month but Chief Executive David Calhoun said this week the company plans to begin ramping up production of the model in anticipation of winning regulatory approval to restart service.

Calhoun began as CEO earlier in January following the ouster of Dennis Muilenburg, who tenure was rocked by the MAX crisis which led to deteriorating relations between the company and the FAA.

Calhoun aims to turn the company around, and has highlighted restoring Boeing's reputation with regulators, customers and other stakeholders as an imperative.

US proposes remote ID requirement for drones

opportunities and help law enforcement track illegal activities (AFP Photo/HO)

Washington (AFP) - US regulators on Thursday unveiled a proposal to require privately operated drones to use remote identification -- a kind of electronic license plate -- as part of efforts to ensure airspace safety.

The Federal Aviation Administration proposal for remote ID is now subject to a 60-day comment period before a final rule is adopted.

Officials said the new rule would help identify potential threats, and presumably enable security officials to act against them.

"Remote ID technologies will enhance safety and security by allowing the FAA, law enforcement, and federal security agencies to identify drones flying in their jurisdiction," said US Transportation Secretary Elaine Chao, whose agency includes the FAA.

According to the text of the rule, the requirement would enable officials to remotely identify any drone in real time and "assist federal security partners in threat discrimination -- allowing them to identify an operator and make an informed decision regarding the need to take actions to mitigate a perceived security or safety risk."

The text noted that the FAA wanted to be able to act against activities such as smuggling of illegal drugs or hazardous substances, unlawful invasion of privacy or illegal surveillance.

According to the agency, drones are a fast-growing segment of the transportation sector, with nearly 1.5 million drones and 160,000 remote pilots registered with the agency. The requirement covers all private drones weighing at least 250 grams (0.55 pounds).

The move comes amid efforts by both large tech firms such as Google parent Alphabet and Amazon as well as startups to use drones for delivery of food, medical supplies and other items.

DJI, the Chinese firm which is a large manufacturer of drones, welcomed the action, saying it could enable drones to be used for complex operations, but added that it would review the details.

"DJI has long advocated for a remote identification system that would provide safety, security and accountability for authorities," said DJI vice president Brendan Schulman.

Boeing ousts Muilenburg, names Chair David Calhoun as CEO

crisis (AFP Photo/ALEX WONG)

New York (AFP) - Boeing on Monday replaced its embattled chief executive, Dennis Muilenburg, saying a change was necessary as it attempts to restore its reputation amid the protracted 737 MAX crisis.

Boeing named board Chairman David Calhoun as chief executive and president, saying the company needed to "restore confidence" and "repair relationships with regulators, customers and all other stakeholders."

The company pledged to "operate with a renewed commitment to full transparency, including effective and proactive communication with the FAA, other global regulators and its customers."

The aerospace giant's financial picture remains clouded following the global grounding of the MAX in March after two deadly crashes.

The move comes a week after Boeing took the monumental step of temporarily shutting down MAX production because of the crisis, which has pushed the aircraft's return to the skies into 2020.

Muilenburg will exit the company immediately but Calhoun, a former General Electric aviation executive, will not take the CEO post until January 13, 2020, while he exits existing commitments, Boeing said in a news release.

During that period, Chief Financial Officer Greg Smith will serve as interim CEO.

Muilenburg's response to the crisis has been increasingly criticized as the MAX grounding has dragged on far longer than initially expected as more disturbing details have dribbled out about the certification of the MAX.

He has also been seen as tone deaf and awkward towards families of the 346 people killed in the crashes.

After enduring two withering congressional hearings in the fall, Muilenburg's leadership came under further scrutiny this month when the Federal Aviation Administration called the company out for overly-optimistic timeframe for restoring the MAX that the agency said created the perception that Boeing was trying "to force FAA into taking quicker action."

Boeing shares jumped 3.4 percent to $339.13 in early trading on the news.

The company took another hit to its reputation over on Sunday when its Starliner spacecraft landed six days early after a failed mission to rendezvous with the International Space Station.

Electric motorcycles ride to rescue in fuel-short Cuba

delayed by fuel shortages (AFP Photo/YAMIL LAGE)

Havana (AFP) - It is rush hour in Havana and the queue at the bus stop is longer than ever. Then a fleet of electric motorcycles appears, beeping their horns.

Surprised and relieved, passengers jump on the backs of the 50 or so electric mopeds.

It is a new solution for Cubans struggling with fuel shortages driven by US sanctions that have curbed oil imports.

Cuba has long been known for the classic American cars that people here lovingly maintain decades after they stopped being built.

But urban transport on the communist island is evolving.

The bikes' horns beep and some of the riders play reggaeton music -- but, being electric, their motors make hardly any noise.

A Chinese-made electric motorcycle costs between $1,800 and $2,300 in Cuba. A basic petrol-powered bike on the island can cost up to six times that.

Volunteer riders

The electric bikes -- with a maximum speed of about 50 kilometers (30 miles) per hour -- were first licensed for import in 2013.

They have multiplied in the streets since then -- and have come into their own with the recent fuel shortages.

"I really like this initiative, it helps a lot with the economy," says passenger Yanet Figueroa, 42, sitting on the back of one of the bikes.

"It really helps people who have great need of it."

Cuba plunged into a fuel crisis in September after Washington imposed restrictions on fuel shipments from Cuba's top ally Venezuela.

Cuba had to make do in September with just 30 percent of its usual fuel supply and the level has still not recovered -- it is forecast to reach no more than 80 percent this month.

With the public transport network badly hit, President Miguel Diaz-Canel has called on drivers to pick up passengers voluntarily.

The owners of electric bikes known as "motorinas" answered the call.

"We have volunteered to do this as a service to society," says one of the drivers, Javier Capote, 33.

"It is going very well. We are very happy about it."

The president himself during a televised address mentioned "those famous... what do you call them, the bikes? The 'motorinas', that have come out to help."

Electric bike era

Cuban authorities estimate there are 210,000 electric motorcycles currently in use on the island.

That figure is expected to rise as the government in late October began to sell them with the price capped at $1,700.

Those who make a living servicing the bikes are pleased by that move as it will bring down costs.

"It seems like a very good idea to us mechanics," says one, Enrique Alfonso, 47, in his workshop.

He recalls the economic crisis of the 1990s that followed the end of cheap imports from the Soviet Union.

"That was the era of (affordable) Chinese bicycles. Now we are in the era of electric motorcycles," he says.

"With everything that is going on the country, they have become obtainable for a lot of people."

Accidents

The electric bikes had a mixed reception at first. Silent and often inexpertly ridden, they are often involved in accidents in a country that already suffers from thousands of crashes a year.

Officials say that of the 7,000 road accidents recorded so far this year, a third have involved electric motorcycles.

Authorities have responded by insisting riders have a license and register their vehicles.

The flourishing of electric bikes follows several years of gradual opening-up of Cuba's state-run economy. It has also coincided with a digital mini-revolution.

Thanks to the availability of 3G-standard internet connections since last year, riders can network more easily.

The 3G connections helped spawn the Electric Motorbikes of Cuba online group, a club with more than 80 members.

It started out as a club for enthusiasts seeking to have "healthy fun and share the passion we all have for electric motorcycles and road safety," says its president Osdany Fleites, a 37-year-old taxi driver.

"The motorcycles do not pollute the environment, they do not make a noise," he says.

Now the club has evolved to have an environmental and "social purpose."

Along with another club, Eracing, its members take part in rescuing bus passengers stuck due to the fuel shortages.

They have also taken part in environmental clean-up jobs, helping eradicate an infestation of troublesome giant snails in Havana, donated blood and visited children in a cancer ward.

Boeing CEO grilled on Capitol Hill after MAX crashes

Washington (AFP) - Boeing chief executive Dennis Muilenburg faced a barrage of criticism from US lawmakers Tuesday at a jammed hearing on the company's commitment to safety as family members of victims of two deadly MAX 737 crashes looked on.

In his first appearance before Congress since the 737 MAX was grounded in March, Muilenburg apologized for the crashes and acknowledged shortcomings, but broadly defended Boeing's development of the ill-fated aircraft.

Senators from both parties signaled clear dissatisfaction, bordering on rage in some cases.

"Boeing is the company that built the flying fortress that saved Europe," said Democratic Senator Tammy Duckworth, a former National Guard helicopter pilot who lost both legs during the Iraq War.

"You have told this committee and you told me half-truths over and over again," said Duckworth, who represents Illinois, home to Boeing's corporate headquarters. "You have not told us the whole truth and these families are suffering because of it."

Muilenburg stuck to the company's longstanding stance that development of the MAX followed time-tested company procedures and defended it against charges that it cut corners on safety and was too cozy with regulators the Federal Aviation Administration.

Many analysts view the hearings as a can't-win situation for Muilenburg and expect him to exit the company in the foreseeable future, most likely after the MAX returns to service.

Asked by a reporter if he would resign, Muilenburg said, "That's not where my focus is. My focus is on the job at hand focused on safety. And we're going to do everything we can to ensure safe flight."

But Nadia Milleron, who lost her daughter on the Ethiopian Airlines crash, said the company needs a shakeup.

Muilenburg "needs to resign. The whole board needs to resign," she said. "I expect him to stop putting the blame on the FAA and other people because that is what they always do. They don't take responsibility."

Passing the buck?

Many of the questions focused on the Maneuvering Characteristics Augmentation System, an automated system that Lion Air and Ethiopian Airlines pilots were unable to control, resulting in crashes.

"We have learned from both accidents and we've identified changes that need to be made to MCAS," Muilenburg told the Senate Commerce Committee.

But Senator Ted Cruz, a Texas Republican, lambasted Muilenburg as he struggled to answer pointed questions about 2016 texts from Boeing pilot Mark Forkner to a colleague that discussed the "egregious" performance of the MCAS during a simulation test and said that he "basically lied to the regulators."

Muilenburg indicated that Boeing counsel shared the documents with the Justice Department in February, but that he did not see the specific exchange until it was reported by news media earlier this month.

"I was made aware of existence of this kind of document," Muilenburg told Cruz. "I counted on counsel to handle this appropriately."

"That is passive voice," Cruz shot back. "You're the CEO, the buck stops with you.

"How did your team not put it in front of you, run with their hair on fire and say 'We have a real problem here?' How did that not happen and what does that say about the culture at Boeing?"

Senator Maria Cantwell, a Democrat from Washington state where the 737 MAX is built, said the crisis showed that Boeing leadership was failing its employees.

"This isn't a question about line workers -- this is a question about the corporate view from Chicago, and whether there is enough attention to manufacturing and certification," Cantwell said. "You should take offense to the fact that people say, 'It's a great company that's not being run correctly.'"

Tuesday's hearing will be followed by a second session on Wednesday in the House Transportation Committee.

Boeing is still targeting regulatory approval for the MAX in 2019, a timeframe that many aviation experts still view as possible.

Senator Roger Wicker, a Mississippi Republican who chairs the Senate committee, told CNBC before the hearing that he intends to scrutinize Boeing's processes but said he did not see anything that would prevent the MAX from going back into service "fairly soon."

"I think this plane is eminently fixable," Wicker told CNBC. "I don't think it's a hopeless cause."

US makes history with first all-female spacewalk

Yahoo – AFP, Issam AHMED, October 18, 2019

spacewalk outside the International Space Station on October 18, 2019 (AFP Photo/HO)

Washington (AFP) - US astronauts Christina Koch and Jessica Meir on Friday became the first all-female pairing to carry out a spacewalk -- a historic milestone as NASA prepares to send the first woman to the Moon.

"It symbolizes exploration by all that dare to dream and work hard to achieve that dream," Meir said after the 7-hour, 17-minute spacewalk to replace a power controller on the International Space Station.

The mission was originally planned for earlier this year but had to be aborted due to a lack of properly fitting spacesuits, leading to allegations of sexism.

Koch and Meir began the walk with standard safety checks on their suits and tethers, before making their way to the repair site on the station's port side, as the sunlit Earth came into view.

In a call to reporters just a few minutes before, NASA administrator Jim Bridenstine emphasized the symbolic significance of the day.

"We want to make sure that space is available to all people, and this is another milestone in that evolution," he said.

"I have an 11-year-old daughter, I want her to see herself as having all the same opportunities that I found myself as having when I was growing up."

Suit flub

The first all-female spacewalk was supposed to take place in March but was canceled because the space agency had only one medium-sized suit. A male-female team performed the required task at a later date.

The failure by traditionally male-dominated NASA to be adequately prepared was denounced in some quarters as evidence of implicit sexism.

When Koch and Meir had been outside the space station for about five hours, President Donald Trump reached them in a video call and told them they had made history.

"You are very brave, brilliant women," Trump said.

"You represent this country so well," the president added. "We are very proud of you."

Meir, a 42-year-old marine biologist who was recruited by NASA in 2013, answered by paying tribute to female pioneers of the past.

"We don't want to take too much credit because there have been many other female spacewalkers before us," she said.

"There's been a long line of female scientists, explorers, engineers and astronauts. We have followed in their footsteps, to get to where we are today."

After the call, the astronauts got back to their repair work.

"That is a view," one of them -- it was not clear which -- said at one point, as the earth was lit up in bright light from the sun.

Koch, an electrical engineer who is leading the mission, was carrying out her fourth spacewalk and was hooked up to the station's robotic arm.

Meir, making her first spacewalk, carefully made her way using handles.

The two were working to replace a faulty battery charge/discharge unit, known as a BCDU.

The station relies on solar power but is out of direct sunlight for much of its orbit and therefore needs batteries. The BCDUs regulate the amount of charge that goes into them.

The current task was announced Monday and is part of a wider mission of replacing aging nickel-hydrogen batteries with higher-capacity lithium-ion units.

Artemis

The US sent its first female astronaut into space in 1983, when Sally Ride took part in the seventh space shuttle mission, and has now had more women astronauts than any other country.

But the first woman in space was Soviet cosmonaut Valentina Tereshkova in 1963, followed by compatriot Svetlana Savitskaya in 1982, who was also the first woman spacewalker two years later.

NASA acting associate administrator Ken Bowersox said he hoped that an all-female spacewalk would soon be a "routine" matter that would not require celebration.

Asked why it had taken so long -- Meir is the 14th US woman spacewalker -- he said men's added height provided an advantage.

"There have been a lot of spacewalks where very tall men were the ones that were able to do the jobs because they were able to reach and do things a little bit more easily," he said.

Democratic presidential hopeful Kamala Harris said the spacewalk was more than historic.

"It's a reminder that for women, even the sky doesn't have to be the limit," she tweeted.

NASA plans to return to the Moon by 2024 for the first time since the Apollo landings of 1969-1972. The new mission is named Artemis, after the twin sister of Apollo in Greek mythology.

The mission will likely see the first woman set foot on the lunar surface, perhaps as part of a male-female combination, as the space agency looks ahead to a crewed Mars expedition in the 2030s.
