WASHINGTON (Reuters) -A U.S. authorities watchdog on Friday sided with NASA about its choice to decide a single lunar lander provider, rejecting a protest filed by Blue Origin and protection contractor Dynetics Inc.

The providers experienced challenged the $2.9 billion award to Elon Musk’s SpaceX for the lander, arguing NASA was essential to make several awards. The Governing administration Accountability Workplace (GAO) stated it “denied the protest arguments that NASA acted improperly in earning a solitary award to SpaceX.”

Blue Origin, the rocket company launched by billionaire Jeff Bezos, explained on Friday it remained persuaded that there have been “fundamental issues” with NASA’s determination, and that GAO was not capable to handle them “due to their constrained jurisdiction.”

Blue Origin said it will carry on to advocate for two rapid companies as it thinks that to be the ideal remedy.

“GAO’s decision will enable NASA and SpaceX to build a timeline for the first crewed landing on the Moon in a lot more than 50 yrs,” NASA mentioned in a assertion on Friday, adding that sending American astronauts to the moon is a priority for the Biden Administration.

Dynetics, a unit of Leidos Holdings, claimed it was disappointed with the final decision, but options to contend for other options introduced by NASA in the long run.

SpaceX did not remark, but Musk sent a tweet saying just “GAO” with a flexed muscle emoji.

NASA experienced sought proposals for a spacecraft that would have astronauts to the lunar surface area underneath its Artemis software to return humans to the moon for the to start with time given that 1972.

In April, NASA awarded https://www.reuters.com/technological innovation/spacex-wins-us-contract-spacecraft-mail-astronauts-moon-washington-post-2021-04-16 SpaceX a agreement to establish this sort of a spacecraft as early as 2024.

Blue Origin experienced contended NASA gave SpaceX an unfair benefit by permitting it revise its pricing.

On Monday, Bezos presented to address up to $2 billion in NASA fees if the U.S. room agency awarded Blue Origin a lunar landing agreement.

In a letter to NASA Administrator Bill Nelson, Bezos claimed Blue Origin would waive payments up to $2 billion, and pay for an orbital mission to vet its technological innovation. In trade, Blue Origin would settle for a company, fastened-priced deal, and include any program development expense overruns.

“Without competitiveness, NASA’s short-phrase and extended-time period lunar ambitions will be delayed, will finally price tag more, and won’t provide the national fascination,” Bezos stated.

Bezos’ offer came six times following he flew along with three crewmates to the edge of room aboard Blue Origin’s rocket-and-capsule New Shepard.

Astronomers spot light from behind a black hole for the first time — proving Einstein right, again


For the first time ever, astronomers have instantly detected light-weight from behind a supermassive black hole. The discovery proves Albert Einstein’s concept of basic relativity was correct — again

Applying the European Room Agency’s XMM-Newton and NASA’s NuSTAR place telescopes, scientists have been observing the black hole as it flung X-rays out into the universe. The black gap is about 10 million periods additional huge than our sunlight, and is found in the middle of a close by spiral galaxy referred to as I Zwicky, 1,800 million mild-a long time absent from Earth.

Right after observing a series of shiny flares of X-rays, a little something unprecedented transpired — extra flashes that have been more compact, afterwards and different “hues” than their predecessors. According to a examine released this 7 days in the journal Character, the “echoes” of mild appeared consistent with X-rays mirrored from driving the black gap — a pretty strange location for light to originate.  

Black holes’ gravitational pulls are so highly effective that gentle can not escape them. On the other hand, light can “echo,” wrapping around the back again of the celestial phenomenon and permitting astronomers to see it. 

“Any light that goes into that black gap doesn’t arrive out, so we should not be ready to see anything that is at the rear of the black hole,” explained lead creator Dan Wilkins in a statement. “The rationale we can see that is due to the fact that black hole is warping place, bending mild and twisting magnetic fields about by itself.” 

While Einstein predicted the skill of a black hole’s gravity to bend gentle close to it in 1916, it has never ever been confirmed — until finally now.

Scientists observed bright flares of X-ray emissions, created as gasoline falls into a supermassive black hole. The flares echoed off of the fuel falling into the black hole, and as the flares were being subsiding, quick flashes of X-rays were observed – corresponding to the reflection of the flares from the far aspect of the disk, bent all-around the black gap by its sturdy gravitational industry.

Dan Wilkins


“Fifty decades back, when astrophysicists starting speculating about how the magnetic area may behave close to a black gap, they had no concept that a person working day we may have the methods to observe this directly and see Einstein’s general theory of relativity in action,” claimed co-writer Roger Blandford. 

Researchers weren’t even on the lookout to validate Einstein’s principle. They were initially making an attempt to uncover the mysteries of an odd function of black holes known as the corona, the resource of the shiny X-ray light-weight. 

“I’ve been developing theoretical predictions of how these echoes seem to us for a handful of several years,” mentioned Wilkins. “I might currently witnessed them in the concept I’ve been producing, so the moment I saw them in the telescope observations, I could determine out the relationship.”

The prevailing theory is that the corona types soon after gas falls constantly into the black gap, forming a spinning disk all around it, “like water flushing down a drain.” The gas disk is then heated up to millions of degrees, generating a twisted magnetic discipline that eventually snaps, releasing its energy and developing the corona.

“This magnetic area getting tied up and then snapping shut to the black hole heats every thing about it and creates these large vitality electrons that then go on to produce the X-rays,” explained Wilkins. 

From here, astronomers hope to use the several “hues” noticed as the X-ray echoes travel all around the black hole to make a 3D map of the black hole surroundings. They also hope to study how the corona generates this kind of vibrant flares.

KUALA LUMPUR (Reuters) – Malaysia has taken enforcement motion in opposition to cryptocurrency system Binance to prevent it functioning in the state, the Securities Fee claimed on Friday.

The Commission claimed it experienced issued a community reprimand in opposition to Binance Holdings Constrained, its CEO Zhao Changpeng and 3 other entities registered in the United Kingdom, Lithuania and Singapore, for continuing to function in Malaysia regardless of being included to the regulator’s investor inform record a 12 months ago.

The regulator requested Binance to disable its site and cellular purposes, stop media and advertising and marketing routines, as nicely as restrict Malaysian traders from accessing its Telegram group.

“Those who at present have accounts with Binance are strongly urged to instantly stop trading as a result of its platforms and to withdraw all their investments straight away,” it mentioned.

Binance reported on Friday it would wind down its futures and derivatives products and solutions offerings throughout Europe as the platform faces rising pressure from regulators throughout the globe.

China’s CATL unveils sodium-ion battery – a first for a major car battery maker



China’s CATL unveils sodium-ion battery – a first for a major car battery maker

July 29, 2021

BEIJING (Reuters) – China’s CATL on Thursday became the first major automotive battery maker to unveil a sodium-ion battery, saying it planned to set up a supply chain for the new technology in 2023.

As electric vehicles become increasingly popular, demand for key battery ingredients, particularly cobalt, has spiked. That has spurred car and battery makers to seek alternatives to the current three main technologies – nickel-cobalt-aluminium (NCA), nickel-cobalt-manganese (NCM) and lithium iron phosphate (LFP) batteries.

The sodium-ion batteries do not contain lithium, cobalt or nickel. It did not disclose cost details of the new batteries.

CATL, China’s top car battery maker with a market value of almost $200 billion, also unveiled a battery pack that integrates sodium-ion and lithium-ion batteries.

The energy density of its new sodium-ion batteries is still lower than that of LFP batteries, Huang Qisen, deputy head of CATL’s research centre told an online briefing. But he added that they perform well in cold-weather and fast-charging scenarios.

CATL, which competes with Japan’s Panasonic Corp and South Korea’s LG Chem, has over 5,000 researchers, its chairman, Zeng Yuqun, told the briefing.

It is also developing other technologies that integrate battery cells directly onto an electric vehicle’s frame to extend its driving range.

Automakers that CATL supplies include Tesla Inc, Volkswagen AG and Geely.
