NASA’s Aqua Satellite captures three Western fires in Utah and Nevada

On July 14 this year, NASA’s Aqua satellite captured an image containing fires in Utah and another one on the Nevada border. The Aqua Satellite used Moderate Resolution Imaging Spectroradiometer (MODIS) to capture the fire images. The fire on the edge of Nevada and Utah is the Big Summit Fire. The location of the Turkey Farm Road Fire was on the north of St. George in Utah, and the little fire was on its West. The satellite captured the last fire that was in the Dixie National Forest. 

Located 17 miles northeast of Panaca, the cause of the Big Summit Fire is under speculation. The fire started on July 13 and spread widely on an area of 4,000 acres, 10 percent of the fire has been contained. Brushes, short grasses, and timber are the fuels burning in the fire. According to weather forecasts, the prevailing conditions may not favor firefighters who anticipate high speedy winds, intense heat, and low humidity. 

On July 13, the Turkey Road fire had already started, and the fire resulted from the unlawful use of fireworks that ignited a blaze in the dry environment. The fire has burnt an area of over 10,000 acres, and no one has contained the fire yet. Their evacuation did, and the fire has already destroyed one out structure. Weather forecasts state that in the next days, the area will still experience high fast winds of 14 mph, reduced humidity, and no rains. 

On July 13, the Veyo West fire, which is found on the West of the Turkey Road Farm fire, also started. The leading cause that resulted in that fire is still under speculation, although some sources say that an improperly put out campfire was its primary cause. The fire has extended to 2,900 acres of land, and there is containment activity carried out as we speak now. 

Instruments in NASA’s satellites are always the first ones to sense burning fires in outlying areas. Also, NASA’s devices help in sensing of actively ongoing fires, tracing the conveyance of smokes from the flames, provide data to land managers for the management of the lights and provide changes in the ecosystem due to the impact of the lights. NASA contains a group of earth-observing satellites, many of which helps us understand fires in our Earth System. Those satellites present in the poles provide vast information concerning our planet, and those in geostationary orbits give course resolution pictures of smokes, fires, and clouds every 5-15 minutes.

The role of hydrogen in clean air transmission

One of the elements that are likely to play an essential role in the clean energy transition is hydrogen. The aspect will be important transport building and power generation sectors because of the most current technology. The need to use hydrogen technology has increased in various niches of transport segments, despite multiple applications. Hydrogen has short-term and medium-term technology that will replace compressed gas in different areas with some little changes in the existing infrastructure, according to the GlobalData. 

Many countries in the world are initiating the development and use of hydrogen technology to handle different use of hydrogen technology to deal with environmental concerns and lead to energy security. Hydrogen gas can handle large-scale and long-term clean energy storage equipment to produce power from renewable sources. On the other hand, developing a well-regulated and cost-effective transition is a complicated issue, including hydrogen production cost from renewable sources of energy.  

According to GlobalData senior Analyst Sneha Susan Elias, Hydrogen can help in different outputs of power from renewable sources, including wind and solar PV. The capacity of the above causes is not consummate with the needs of power.

The amount of hydrogen used for electricity is less than 0.2 percent of the total electricity generated in the power industry. Hydrogen electricity consumers are steel petrochemical industries and many refineries, although shortly it might change. Co-firing with ammonia share might decrease carbon’s effect in the existing conventional power plants for coal, combined cycle gas turbines (CCGT), and the hydrogen gas turbines, which are power sources with systems that are flexible with many amounts of variable energy renewable sources. 

The drop in the amount of solar PV, and the power from wind generation, the development of electrolyzes at different places have a significant impact on renewable sources. It can serve as the best alternative for a low-cost supply of hydrogen even when the transmission and distribution into account. The cost of the transfer of hydrogen and distribution is low, making it easy to use hydrogen from renewable sources cheap to the end-user.  The decrease in the price of the production of hydrogen will lead to the reasonable cost of electricity; thus, most users will prefer to use hydrogen electricity in different sectors, thus reducing the carbon emission in the atmosphere. The carbon emission in the atmosphere has lead to the change of climate and an increase in diseases.

China’s Kuaizhou-11 rocket malfunctions a few hours after taking off

China reveals that the launch of the Kuaizhou-11 rocket is a fail. This statement comes after the rocket took off from the Jiuquan Satellite Launch Center in Northwest China on the 10th of July. The impertinent source of the problem is still under study. This failure comes a day after a similar launch from this Xichang Satellite Launch Center was successful.

The state media, known as Xinhua, submitted in a press release that the break down began a few minutes after takeoff. The exact time is estimated to be at 12:17 p.m. The media house states that the cause of the malfunction is still under analysis and evaluation.

A snippet of the launch is online, displaying the initial moments of glory for the rocket after its launch. The video demonstrates a successful detachment of the first and second segments. This video is already on the SpaceNews.com website.

Kuaizhou-11 or the KZ-11 was trying out its first launch after days of postponement as it was modified to host two satellites to space. NASASpaceflight.com admits that the rocket has been under development, and its first mission was supposed to be in 2018.

The failed rocket launch resulted in the loss of two satellites with it. CentiSpace-1 S2 (Xiangrikui 2 or Weili-1-02), one of the two satellites, was to form part of the constellation of satellites in the low-Earth orbit path. The other rocket, Jilin-1 Gaofen-02E (BilibiliSat), is a telemetry satellite whose commercial purpose is to control geological challenges and natural resources.

KZ-11 is a creation of the China Aerospace Science and Technology Corporation. NASASpaceflight.com reveals that the China Space Sanjiang Group Corporation (Expace) is responsible for advertising this rocket. This rocket can carry a payload worth 100 kilograms to the sun-synchronous orbit, which is in the medium-altitude Earth orbit. It can also send a payload of about 1500 kilograms to the low-Earth orbit. An analyst of SpaceNews.com explains that the KZ-11 is a project started to act substantially as a top-up to government-sponsored launches.

This launch was supposed to be China’s 19th launch this year before the catastrophic failure. There was the 18th launch the day before this, which triumphantly carried APSTAR-6D communications satellite to space via the experienced Long March 3B rocket. This launch was initiated at 8:11 p.m and was photographed by China Central Television (CCTV), a state-owned media house.

Finally, APSTAR-6D will voyage space in its geostationary orbit for the next 15 years. This satellite forms the basis of a broadband satellite connection system responsible for communications in the Asia-Pacific region. This satellite is going to provide high-speed communications with around 50 gigabytes per second. The APSTAR-6D is a creation of the China Academy of Space Technology, a branch of China Aerospace Science and Technology Corporation.

“Grave error” for FCC Ligado Order

A committee responsible for advising the US government on space-based navigation services came up with a conclusion that the approval of the Ligado’s 5G network by the Federal Communication Commission is a risky decision that endangers the Global Positioning System services. 

A meeting held online on July 1, members of the National space-based Positioning, Navigation, and Timing Advisory Board extensively debated the report composed for the committee. The report was about the April FCC conclusion to let Ligado run a 5G tellurian network on a spectrum band adjacent to the one used by GPS. 

“It has suddenly altered the entire disposition of the radio spectrum close the GPS main frequency,” Brad Parkinson, the chief Architect of the GPS and vice-chair of the committee. “It is a grave error made by FCC for allowing a robust tellurian communication network on a range band adjoining to the GPS.” He added.

He also pointed out that the original spectrum’s intention was to be used by the mobile satellite systems with weaker signals than those Ligado is planning to utilize in the band. “The re-planning of this spectrum is a risky affair, and brings no near-term advantages to the United States,” he said. 

Parkinson said that the lack of any advantage is due to the lack of 5G hardware or standards plotted to operate at the L-band frequencies Ligado goals to use. He argued that the possible interference would outweigh any benefit that would accrue to the GPS signals from the Ligado’s excessive power signals, which he extensively talked about in his presentation. 

“There is no positive outcome on the United States’ competitive posture by the FCC order. This is because the order may harm the GPS reputation due to the damage it does,” he concluded. 

Apart from the committee, the FCC decision on Ligado has also faced criticism from various government agencies, the Defense Department, and some members of Congress, mainly due to the interference worries. However, the FCC commissioners who adopted Ligado order have continuously argued that the company agreed to reduce power levels, which will prevent interference. 

The committee members who supported the Parkinson report said that the FCC approval of the Ligado could cause the same interference for various space-based navigations systems and could set a bad precedent for other countries to develop similar systems. 

However, the committee did not offer any recommendations on how to reverse it and stated that they intend to issue a public statement on how they feel concerning the Ligado approval.

Some of the vital details concerning electric vehicles

Currently, electric vehicles range from trucks, rickshaws, motorcycles, cars, transit buses, and even tractors, which are hybrids. These vehicles are classified into three, namely plug-in hybrids, fuel cell vehicles, and battery electric vehicles. The plug-in hybrids take in both gasoline and can also be run by a rechargeable battery. On the other hand, fuel cell vehicles run on hydrogen energy technology, and battery electric vehicles operate on electricity coming from a battery pack. 

Electric vehicles will solve the problem of greenhouse gas emissions and global warming. Gasoline or petrol cars are the main sources of air pollution in countries like America. The gases from these cars cause health complications like cancer, bronchitis, and even death. For instance, a gallon of diesel comes with up to $3.80 of human health and ecological costs courtesy of a study at Duke University. 

The carbon footprints left by diesel or petrol cars are bigger than those of electric vehicles independent of the source of EV power. The electricity for electric vehicles comes from a range of sources but most especially from power grids. The carbon print left by an EV varies depending on the source of electricity. Electricity generated for Evs is the cleanest and cost-effective even when it is emanating from the dirtiest source. 

Electric vehicles are vital in controlling climatic conditions. The only challenge these cars pose is they increase global warming when their batteries are being manufactured. However, the vehicles’ operation covers this problem in less than eighteen months of driving, thereby outshining petrol cars in minimizing pollution. 

Electric cars are advantageous because they can charge at work, at home, or at the store provided there is a power grid and a charging station nearby. This concept enhances trucks and buses’ efficiency, which have central depots and stopping points at which they can charge. Currently, charging stations are being installed at crucial points like malls, parking lots, and workplaces. 

Various states and utilities intend to erect structures to facilitate the charging of electric vehicles. The utilities hope that there will be charging stations at strategic locations to enhance the general public’s swift exploration of electric cars. The US federal government says that it is up to each state to establish its grid and spread the charging stations’ installation. 

Various states are thinking of replacing the transit buses with electric buses. This move will facilitate a cheap and convenient mode of public transport that caters to everyone and mind the safety of the environment. 

In conclusion, delivery trucks should also be electrified. This concept will curb pollution in cities and towns since these are the places with a vast number of businesses requiring deliveries.

Tesla and Scientists help in the success of affordable ‘million miles’ electric vehicle battery

 Letter ‘R’ might become the main difference that boils the future of the auto industry. In other words, the difference between Lithium-Iron phosphate batteries that will be available on the market soon and Lithium-Ion batteries, which are present in the current vehicles. 

Tesla, an Elon Musk firm, has begun to embrace the development of electric vehicle technology, which will lead the firm to the first-ever Battery Day for Stakeholders. Buzz street is producing the significant differences that the future batteries will have. 

Cars that use Lithium-ion batteries, the same used in cellphones, will give their way forward about the vehicles and trucks that use Lithium-iron phosphate batteries. Such cells will make the cars more affordable, increase the distance to 400 miles, which will enable the battery to last for long. 

Minimizing the own prices of Tesla and instigating large numbers of customers to embrace electric vehicles remain an essential priority for Tesla. 

The recent technology used in cars will change the experience of owning a vehicle, irrespective of the firm that manufactured it, whether Tesla of its competitor, General Motors. 

Discussing batteries that go for more extended periods, for the same cost completely changes the calculations made by the user. Iron Phosphate batteries are way much better, safer, and have second to third lives as electricity storage. 

In a statement released by Shirley Meng, a materials expert and a professor at the University of San Diego, California, abilities done to reduce the use of Cobalt have progressed over time, and Tesla has made notable moves with the help of Dahn.  Meng also stated that the fitting batteries with Cobalt make it easy to engineer complex chemical constituents, making it advantageous. 

However, from various researches conducted, Lithium Iron-Phosphate does not prove to be good enough for electric vehicle consumer use. Initially, its design was meant for the grid storage market due to its energy density profile. Although, the science behind the battery fits it to fast-charging and cost-efficient since it does not depend on Cobalt. 

Meng has worked on the chemistry of batteries and development with renowned firms like GM, Mercedes-Benz, Maxwell Technologies, and Nissan. Researchers are curious to know the progress of Tesla, and they hope that the firm has made Lithium-iron phosphate profile known to the market of electric vehicles. 

For once, the battery technology tried to jump successfully from energy storage to cars in Fisker Karma.

NASA makes the foremost move to jet spacemen on suborbital business automobiles

NASA is building its foremost move in a procedure that could amount to spacemen and other organization’s staffs jetting on a suborbital business automobile by creating a program office and looking for contributions from the industry.

On the 23rd of June, NASA proclaimed that it had initiated an office with the business group program, dubbed Suborbital Crew that would advance a protocol for NASA staff to jet on automobiles like the Blue Origin’s New Shepherd.

That attempt will concentrate on advancing what NASA terms as system qualification of suborbital business automobiles to measure their security. The moment those kinds of automobiles finalize the qualifications, NASA will look into purchasing seats on trips for study and exercise.

Kathy Lueders mentioned about how industries could advance ground-breaking crew conveyance system that aligns with NASA’s precaution necessities and standards. Aspects such as experience and flight history would be considered to permit NASA staff members to jet.

To back that attempt, NASA unveiled an RFI looking for a contribution from the suborbital shuttle flight community on the system requirement protocol.NASA is also searching for data on the price of such flights, jetting rates alongside other details.

 Data about precaution on suborbital automobiles has been demanded by the RFI, with matters such as accident sustainability and extenuation inclusive, system dependability, and how the corporations determine and uphold the reliability of serious systems for a suborbital way of the human race to the orbit.

NASA quotes within the RFI that it has no plans of duplicating actions via the Federal Aviation Administration for intentions of certifying, it probes for data concerning traveler safety like what assists a traveler to uphold caution when giving chances to do scheduled trials and experiment programs. The Federal Aviation Administration’s office of business space conveyance is presently restrained from regulating precautions of space travels contributors on business automobiles. This restraint presently prolongs to twenty-twenty three.

In the publication, NASA highlights three stages of activities that would need suborbital business travels. One is an exercise for spacemen, alongside facing ascent, microgravity while the second one is trying out and requirement, and lastly is the human-tended microgravity study.

Creation of the SubC office, as well as the RFI, are some of the public moves made by the organization since Jim, the administrator of NASA, displayed his concern in jetting staff members on such automobiles at the onset of this year. Jim also made an announcement some time back in March that the organization would chase after certification of suborbital automobiles to permit NASA personnel such as the spacemen to jet on them.

China announces its step-ahead in Ultra-secure satellite transmission

Researchers obtained quantum physics to convey a ‘secrete key’ for coding and decoding data between two points of about 700 miles apart. 

The world of human-made satellites, silent in the vacuum of space, might sound calm. It seems to be a high-flying war field widespread with hard situations, cunning, hoax, hacking, and the growing rivalry between the arrays of spaceship and space authorities. 

As of the present time, scientists from China affirm new growth in making what seems to be a primary firm data bridge between a revolving ship and its ground-dwelling controllers. Odds have shown that Beijing might possess one of the super-safe planetary communication networks. 

In a Nature on Monday journal, a group comprising of 24 researchers explain an accomplished experiment on the conveyance of a ‘secrete key’ that codes and decodes data between a satellite and two base points located approximately 700 miles from each other. The idea obtains quantum physics, which entails the present technology and appears to be absurd with probabilities of basic logic. It posits that a couple of well divided subatomic particles can still seem to be taking place gradually. 

Taking measurements of one’s possession affects the measured results instantaneously as much as the two are millions of light in separation. Albeit Einstein termed quantum bombardment as ‘ a scary action from far.’

Authors from China who first reported accomplishment in a bombardment during a satellite operation in 2017 currently reveal that they have increased its functionality. They also show that there are low rates of mistakes, and it will better to use quantum bombardment for the transfer of cryptographic keys.  The summary of the Nature journal states that researchers had an illustration showing the structure producing a safer channel that is resistant to attacks. 

Old communication satellites used waves of radio to convey signals. On the contrary, the quantum communication satellites use a couple of looped photons, or in other words, light particles. Their characteristics remain twisted as one particle of light travels over a  long distance. Information is sent by controlling the photons. 

In August of 2016, China inaugurated the planet’s first satellite from the Gobi desert. The moon experimented with the conveyance of quantum data on photons. They named the spacecraft ‘Micius’ following the Chinese philosopher during the 5th century. The satellite produced a consolidated collection of laser light to provide quantum indications between two telescopes erected between earthy stations in Delingha and Nanshan in China, approximately 700 miles from each other.

New Solar Venture to Prove Beneficial for Indonesia

The Indonesian government plans to embark on a new solar panel project across the country. The idea was a result of the country’s efforts to recover from the just-ended coronavirus pandemic. The venture is a 1bilion dollar plan to help mute economy recuperate. According to the ambitious plan, the government is to layout a thousand solar panels on buildings.

The combined output of the panels is expected to be a rough estimate of 1gW of peak power annually. According to locally established energy company Institute for Essential Services Reform IESR, the project will be able to provide up to 22,000 jobs to locals around.  

These recruits are to be mandated to Putting up the panels. With this in mind, the government also plans to save close to 1 billion dollars in electricity subsidies. The projects, previously named the solar archipelago plan will handle a total cost of fifteen trillion Euros annually spread across the next 4-5 years.  

According to the plans, the government aims to set up thousands of panels across Indonesia’s rural sector to save on the cost of spreading electricity across the nation. As stated by the executive director of IESR Fabby Tumiwa, the organization aims to integrate the plan early next year. However, the company has started preparations from this day. In retrospect, the plan has gained foot over this year. On the other hand, Fabby confirms that there is still a lot left to be done that includes training new personnel as solar panel installers. 

As it stands currently, the country cannot generate one gigawatt of power in one year. Looking at this, the realistic approach would be to install approximately 100-200 megawatt solar structures in Nusa Tenggara and Bali during the first year. The reason for this is that these regions show the largest costs in terms of electricity distribution in all of Indonesia. 

The funding for the project will come from past grant financing to countries for recuperating in the post-COVID-19 economic recovery schemes. However, experts report that these developments enable the economy to push past its limits and create employment opportunities without compromising environmental sustainability.

Consequently, the government has an option to transfer the funding and develop Indonesia’s coal sector. GIZ program coordinator Rudolf Rauch relayed to the Post that coal is not a viable option for the country’s energy needs. However, he pushed more to the fact that the country is not in a position to effect a 1GW plan any time soon. However, the government has in its plans to roll out an effective measure for the solar project eventually.

Electric Vehicle sales in Asia are plummeting.

Makoto Uchida, the CEO of Nissan Motors, was hoping for the financial recovery of his company after uneventful three months of the novel coronavirus pandemic. The firm is famous as a frontier in the EV market with its Nissan Leaf. Makoto says that it will require more financial restructuring before they can realize profits.

Uchida reports that they will be unveiling new electric cars with a driving assistance technology with the hope that the market positively responds to it, especially China. He said that Nissan is a step ahead to transition consumers into EV technology. Shortly, Volkswagen’s response came in detailing its plan to take over 50% of the China market in their collaboration with JAC Motors, thereby raising its market share to 75%. On the other hand, Tesla, May’s best-seller in Evs, has announced their contract with a Chinese bank to take up a loan for scaling up the Gigafactory Shanghai production firm.

However, these plans are out of context considering the current short-term sales figures. China, for instance, is posting low sales figures throughout the automobile market despite the annual growth propelled by government incentives. Consumers are not confident with the vehicles, especially with the meddling of the government. The customers are curious to understand how there’s no expansion in other markets. The situation is contrary to Europe, where consumers are flooding the market with demands for Evs to solve the long-term environmental pollution problem.

Experts idealize that the government involvement in the automobile industry is confusing consumers and therefore deterring them from buying. This theory is perfect considering the subsequent fall in targets of the carmakers. Additionally, consumers are stranded with the massive influx of a variety of vehicles and, therefore, unable to choose the car worth their money value.

China’s sales plunged with an expectation of government subsidies cut. However, the industry still generates over 6 billion yuan from state-owned firms while calling for the layoff of more than 2000 workers. After witnessing the downturn in sales, Beijing says that the subsidies are going to have a two-year extension. However, experts speculate that this consumer luring technique leaves them in dismay whether to venture the EV purchase or not.

Meanwhile, Europe is experiencing a definite surge in electric car sales for the first three months of 2020.  After that, there is a drop amidst the COVID-19 pandemic. The EU further promotes EV transition with stringent policies on emissions and gives incentives for electric vehicle manufacturers. This move accounts for EV growth in the region.

EV manufacturers in Asian countries are struggling because of the stringent regulations on using Lithium-ion batteries rather than conventional lead-acid batteries. Additionally, lowering costs for EV cars is an early move that is detrimental for carmakers given their potential for massive purchase.

Finally, another factor burdening the market is the few batteries charging stations. This factor renders the market impenetrable unless the firms install charging stations countrywide.
