Oil Declines After OPEC+ Wagers Market Can Absorb Extra Barrels

(Bloomberg) — Oil eased after OPEC+ decided to boost output over the coming months and Saudi Arabia raised prices for shipments to customers in Asia.West Texas Intermediate dipped 0.4%, paring the 3.9% gain seen on Thursday, when the alliance agreed to loosen its supply curbs gradually. The grouping will raise production by more 1 million barrels a day in stages between May and July, and over the same period, Saudi Arabia will roll back its voluntary 1-million-barrel-a-day reduction. Markets were closed on Friday for a holiday.Crude has surged this year as the roll-out of coronavirus vaccines paves the way for the reopening of economies, and the decision by the Organization of Petroleum Exporting Countries and its allies was seen as a vote of confidence in the outlook. Reinforcing the signs that top economies are on the mend, the U.S. added more than 900,000 jobs in March. That bodes well for oil demand.Before Thursday’s meeting, the cartel had been expected to maintain its cautious stance by rolling over the cuts that applied to most countries, although Russia had been allowed an increase at the previous gathering. Saudi Energy Minister Prince Abdulaziz bin Salman said OPEC+ was now “testing” the market, and can reverse course if necessary at the next session on April 28.“OPEC+ tapering was more of a compromise, rather than its confidence in market recovery,” said Vandana Hari, founder of Vanda Insights in Singapore. “Another rollover — with another round of dispensation for Russia — might have strained the cohesion in the alliance.”After the OPEC+ meeting, Saudi Arabia raised prices for shipments to Asia. Saudi Aramco, the state energy firm, will increase its grades to the region in May by 20 to 50 cents a barrel. Most prices for North West European customers won’t be changed, while most grades to the U.S. will be cut by 10 cents.Progress in combating the pandemic remains mixed, with an accelerating pace of vaccinations in the U.S. contrasting with renewed curbs elsewhere, especially in Europe. In France, cases have surged due to more contagious variants, forcing a third lockdown. In India, Mumbai authorities asked all private offices to work from home this month after a new wave of infections.“Crude may be in a stalemate for the time being, awaiting further cues from demand,” said Hari. “I expect a continuing tug-of-war on sentiment between a Europe in lockdown and a U.S. racing toward freedom.”Brent’s prompt timespread was 37 cents in backwardation. That’s a bullish pattern — with near-term prices trading at a premium to those further out — and it’s up from 6 cents last Monday.For more articles like this, please visit us at bloomberg.comSubscribe now to stay ahead with the most trusted business news source.©2021 Bloomberg L.P.

Inspiration4 Lift Off: SpaceX Launches World’s First All-Citizen Mission in Earth’s Orbit – Illinoisnewstoday.com

Published

Tampa, Florida (WFLA) — SpaceX made history on Wednesday night when it launched the world’s first all-civil mission to get going from the Space Coast, Florida.

The Inspiration4 mission took off from Launch Complex 39A at NASA’s Kennedy Space Center around 8:03 pm on Wednesday. The four crew members on the SpaceX Dragon spacecraft were launched onto a reusable Falcon 9 rocket and later separated from the spacecraft and landed on the drone.

The mission’s five-hour launch window began at 8:02 EST. The window was very large, as the crew was sent to orbit the Earth rather than the International Space Station, and therefore did not have such strict time constraints.

The crew is set to travel 350 miles above the surface of the Earth, about 100 miles higher than the International Space Station.

“This is important and historic, because it’s the best time humans have been in orbit since the Hubble Space Telescope mission,” said Benjireed, SpaceX’s manned spaceflight director.

The crew will spend three days in orbit to participate in research experiments on human health and performance. We hope that the results of our research will apply not only to future space flight, but also to human health here on Earth.

Inspiration4’s main goal is to provide and inspire support for St. Jude Children’s Research Hospital. They want to raise $ 200 million for St. Jude in a three-day mission.

According to SpaceX, each of the four members of the crew was chosen to represent the pillars of a mission of prosperity, generosity, hope and leadership. The Inspiration 4 crew and the pillars they represent are:

  • leadership: 38 years old Jared Isaacman – Founder and CEO of Shift4Payments
  • Hope: 29-year-old Haley Arseno – Doctor assistants and childhood cancer survivors treated with St. Jude
  • Generosity: 41 years old Chris Sembroski – Lockheed Martin US Air Force veteran and aerospace employee
  • prosperity: 51 years old Dr. Cyan Proctor – Entrepreneurs, educators, trained pilots, and the active voice of the space exploration community

SpaceX trained all four crew members as commercial astronauts on Falcon 9 and Dragon spacecraft. The crew was trained in orbital mechanics, microgravity, weightlessness, other stress tests, emergency preparedness, and spacesuit training.

The mission was funded by Isaacman in a private transaction with SpaceX. Isaacman has also invested $ 100 million towards a funding target for the St. Jude mission.

'Flying' microchips could ride the wind to track air pollution – Yahoo Movies Canada

Published

 on


Researchers have created a winged microchip around the size of a sand grain that may be the smallest flying device yet made, Vice has reported. They’re designed to be carried around by the wind and could be used in numerous applications including disease and air pollution tracking, according to a paper published by Nature. At the same time, they could be made from biodegradable materials to prevent environmental contamination. 

The design of the flyers was inspired by spinning seeds from cottonwood and other trees. Those fall slowly by spinning like helicopters so they can be picked up by the wind and spread a long distance from the tree, increasing the range of the species. 

The team from Northwest University ran with that idea but made it better, and smaller. “We think we’ve beaten biology… we’ve been able to build structures that fall in a more stable trajectory at slower terminal velocities than equivalent seeds,” said lead Professor John A. Rogers. “The other thing… was that we were able to make these helicopter flyer structures that are much smaller than seeds you would see in the natural world.”  

They’re not so small that the aerodynamics starts to break down, though. “All of the advantages of the helicopter design begin to disappear below a certain length scale, so we pushed it all the way, as far as you can go or as physics would allow,” Rogers told Vice. “Below that size scale, everything looks and falls like a sphere.”

The devices are also large enough to carry electronics, sensors and power sources. The team tested multiple versions that could carry payloads like antenna so that they could wireless communicate with a smartphone or each other. Other sensors could monitor things like air acidity, water quality and solar radiation. 

The flyers are still concepts right now and not ready to deploy into the atmosphere, but the team plans to expand their findings with different designs. Key to that is the use of biodegradable materials so they wouldn’t persist in the environment. 

“We don’t think about these devices… as a permanent monitoring componentry but rather temporary ones that are addressing a particular need that’s of finite time duration,” Rogers said. “That’s the way that we’re envisioning things currently: you monitor for a month and then the devices die out, dissolve, and disappear, and maybe you have to redeploy them.”

NASA splits human spaceflight unit in two, reflecting new orbital economy – WION

Published

” class=”ff-og-image-inserted”>

NASA is splitting its human spaceflight department into two separate bodies – one centered on big, future-oriented missions to the moon and Mars, the other on the International Space Station and other operations closer to Earth.

The reorganization, announced by NASA chief Bill Nelson on Tuesday, reflects an evolving relationship between private companies, such as SpaceX, that have increasingly commercialised rocket travel and the federal agency that had exercised a US monopoly over spaceflight for decades.

Nelson said the shake-up was also spurred by a recent proliferation of flights and commercial investment in low-Earth orbit even as NASA steps up its development of deep-space aspirations.

“Today is more than organizational change,” Nelson said at a press briefing. “It’s setting the stage for the next 20 years, it’s defining NASA’s future in a growing space economy.”

The move breaks up NASA’s Human Exploration and Operations Mission Directorate, currently headed by Kathy Leuders, into two separate branches.

Leuders will keep her associate administrator title as head of the new Exploration Systems Development Mission Directorate, focusing on NASA’s most ambitious, long-term programs, such as plans to return astronauts to the moon under project Artemis, and eventual human exploration of Mars.

A retired deputy associate administrator, James Free, who played key roles in NASA’s space station and commercial crew and cargo programs, will return to the agency as head of the new Space Operations Mission Directorate.

His branch will primarily oversee more routine launch and spaceflight activities, including missions involving the space station and privatization of low-Earth orbit, as well as sustaining lunar operations once those have been established.

“This approach with two areas focused on human spaceflight allows one mission directorate to operate in space while the other builds future space systems,” NASA said in a press release announcing the move.

The announcement came less than a week after SpaceX, which had already flown numerous astronaut missions and cargo payloads to the space station for NASA, launched the first all-civilian crew ever to reach orbit and returned them safely to Earth.
