Space missions are becoming increasingly complex – lessons from Amazon and FedEx could help manage satellites and spacecraft in orbit

Published

on

Most space mission systems have historically used a single spacecraft designed to finish all the mission by itself. Whether it was a weather satellite or a human-crewed module reminiscent of Apollo, almost every spacecraft has deployed and accomplished its single mission entirely by itself.

But today, space industry organizations are exploring missions with multiple satellites working together. For example, SpaceX Starlink Constellations encompass 1000’s of satellites. And recent spacecraft may soon have the power to attach or engage other satellites in orbit to make repairs or refuel.

Some of those spacecraft are already in service and serving customers reminiscent of Northrop Grumman mission extension vehicleThis circling ship has prolonged the lifetime of many communication satellites.

The Northrup Grumman spacecraft is an example of a ship designed to service other satellites and spacecraft in orbit.

These recent design options and in-orbit capabilities make space missions more like large-scale logistics operations on Earth.

We are researchers who studied the space industry for years. We have been investigating how the space sector could draw conclusions from corporations like Amazon and FedEx to manage complex fleets and coordinate operations.

Lessons from the Ground Transportation Network

Space mission designers plan routes to deliver payloads to the Moon or Mars or orbit efficiently inside a set of cost, schedule, and capability constraints. But when they need to coordinate multiple spacecraft working together, route planning can grow to be complicated.

Logistics corporations on Earth solve similar problems day-after-day and transport goods and raw materials all over the world. So scientists can study how these corporations manage their logistics to help space corporations and agencies learn find out how to effectively plan mission operations.

One NASA-funded study in the early twenty first century got here up with the thought of ​​simulating space logistics operations. These researchers viewed orbits or planets as cities, and the trajectories connecting them as routes. They also viewed cargo, consumables, fuel, and other items to be transported as commodities.

This approach allowed them to have a look at the issue of space missions from a special perspective, treating it as a cargo flow problem—the sort of query that ground logistics corporations work on on a regular basis.

Lessons from Ground Logistics Infrastructure

New refueling options and repair of spaceships in orbit create recent opportunities, but additionally challenges.

Namely, space operators typically don’t know which satellite will fail next, or when. For these recent technologies to be useful, space mission designers would want to create an infrastructure system. This could appear to be a fleet of service vehicles and repositories in space that respond quickly to any unexpected events.

Fortunately, space mission designers can learn from ground-level operations. City planners and emergency response organizations take into consideration these sorts of challenges when determining where to locate hospitals or fire stations. They also consider the power of those facilities to answer unpredictable calls.

We can draw an analogy between the design of a ground logistics system and the design of an area service system. In this fashion, researchers can use theories developed for ground logistics to enhance the practice of space mission design.

One study published in November 2020 developed a framework for operating spacecraft in orbit using what logistics experts call spatial queue theory. Scientists most frequently use this modeling theory to investigate the performance of the bottom logistics system.

Lessons from Above Ground Warehouse Management

In the past, individual spacecraft carried out their missions independently, so if a satellite failed, the engineers liable for the mission needed to develop and send a alternative.

Now for multi-satellite missions like Iridium satellite constellationoperators often maintain a number of spares in orbit.

This becomes complicated for constellations of a whole lot or 1000’s of spacecraft. Mission designers wish to ensure they’ve enough spare satellites in orbit in order that they do not have to abort the mission if one goes down. But sending too many spare satellites gets expensive.

When coping with these kinds of large constellations, mission designers can learn from the methods Amazon and other ground-based corporations use to manage their warehouses. Amazon places these warehouses in specific locations and stocks them with specific items to ensure deliveries are handled efficiently.

Supply chain managers on Earth are grappling with the identical questions that mission designers in the space industry are starting to face, reminiscent of find out how to manage inventory.

Putting inventory management theories into practice can help space corporations address these challenges.

Test published in November 2019 developed an approach that space corporations could use to manage their backup strategies. This approach could help them resolve where in orbit to allocate their backup satellites to satisfy their needs while minimizing any service disruptions.

International dimensions

Spacecraft operate in a complex and rapidly changing environment. Operators must know where other missions are operating and what rules they need to follow when refueling or repairing in space. But in space, nobody has yet defined these rules.

Ships, planes and ground vehicles have clear traffic rules to follow when interacting with other vehicles. For example, civilian ships and aircraft must share their location with other vehicles and officials to help manage traffic.

Some researchers are investigating what similar rules might appear to be in space. One study examined how developing rules based on a spacecraft’s size, age, or other attributes might help future space operations run more easily. For example, one rule is likely to be that a spacecraft that was launched most recently should take responsibility for maneuvering when one other ship is in its path.

As more satellites and spacecraft are launched than ever before, corporations and government agencies will need recent technologies and policies to coordinate them. As space activities grow to be more complex, scientists can proceed to use what they learn on the bottom to recent missions in space.

No, the boom in battery factories in America is not over – construction of the largest factories is proceeding as planned and it is planned to employ over 23,000 people

Published

on

By

The United States is experiencing the largest-ever boom in investment in clean energy production, driven by laws such as the bipartisan bill Act on infrastructure investments and employment and Act on reducing inflation.

They have these rights used billions of dollars government support to drive private sector investment in clean energy supply chains across the country.

For several years, one of us, Jay Turner, and his students at Wellesley College have been tracking clean energy investments in the U.S. and sharing the data on the website The big green machine website. This study shows that since the Inflation Control Act went into effect in 2022, firms have announced 225 projects with a complete investment of $127 billion and the creation of greater than 131,000 latest jobs.

You could have seen on the news that these projects are in danger of failure or significant delays. In August 2024, the Financial Times reported this. 40% of over 100 projects he assessed that they were delayed. These include battery production, renewable energy and metals and hydrogen projects, as well as semiconductor manufacturing plants. The technology industry magazine The Information recently warned of this 1 in 4 firms left from government subsidies for investment in batteries.

Workers assemble battery packs for electric vehicles in Spartanburg, South Carolina. New battery factories in the state will help move the supply chain closer to U.S. electric vehicle factories.
BMW

We checked all 23 battery cell factories announced or prolonged since the Inflation Reduction Act was signed into law – just about all of them are gigafactories which might be expected to produce greater than 1 gigawatt-hour of battery cell capability. These factories have one of the highest employment potentials of all the projects supported by the Act.

We wanted to discover whether the U.S. clean energy production boom was about to fizzle out. Most of what we learned is reassuring.

The largest battery factories are on the right track

While exact investment amounts are difficult to determine, our study shows that planned capital expenditure shall be $52 billion, which would supply 490 gigawatt-hours of battery production capability per 12 months – enough to put about 5 million latest electric vehicles on the road.

While not all 23 firms have announced hiring plans, the facilities are expected to create nearly 30,000 latest jobs, with projects primarily in the U.S. Southeast, Midwest and Southwest.

We wanted to know whether these projects were progressing as planned or whether there have been delays or problems.

To do that, we first contacted local and state economic development agencies. In many cases, local and state tax incentives support these projects. Where possible, we now have tried to confirm the status of the project through public data Or formal announcements. In other cases, we looked for messages to see in the event that they existed construction proof Or hiring.

Our study shows that 13 of 23 projects are on the right track, with total planned capital investment exceeding $40 billion and production capability of nearly 352 gigawatt hours per 12 months. Importantly, they include most of the largest projects with the largest investments and expected production.

Our calculations show that 77% of total planned capital investment, 79% of proposed jobs, and 72% of planned battery production are on the right track, meaning the project is likely to be accomplished roughly on time and overall as expected. result. level of investment and employment.

Three projects are on the bubble. These have shown progress but have experienced delays in construction or financing.

Five others show deeper signs of distress. We do not yet have enough information to draw conclusions about the two projects.

An example of an ongoing project is the Envision AESC battery plant in Florence, South Carolina. His the scale has been enlarged twice since it was first announced in December 2022. It is now a $3 billion investment with the goal of producing 30 gigawatt-hours of batteries per 12 months supplies the BMW factory in Woodruff, South Carolina.

In early October 2024, South Carolina Secretary of Commerce Harry Lightsey visited the Envision i facility published a video. Construction of the plant began in February 2024, and 850 employees are working six days per week to complete the 1.4 million square foot facility by August 2025. Once full production begins, the project shall be accomplished expected to hire 2,700 people.

The 2024 elections could end or speed up the boom

However, much relies on what is going to occur in the upcoming elections.

Our data suggests that the real risk facing these projects and projects like them is not sluggish demand for electric vehicles, as some suggest – in fact demand continues to grow. It’s not the local opposition that did it either it only slowed down a number of projects.

The the biggest risk is policy change. Many of these projects are counting on advanced manufacturing tax credits approved by the Inflation Reduction Act through 2032.

During the campaign, Republicans are promising to repeal key laws under Biden, including the Inflation Reduction Act, which incorporates funding for grants and loans to support clean energy, as well as tax incentives to support domestic manufacturing.

While an entire repeal of the Act could also be unlikely, an an administration hostile to clean energy redirect unspent funds to other purposes, slow the pace of grants or loans by slow project approvals, or find other ways to make tax incentives tougher to obtain. Although our research focused on the battery industry, concerns concern investments in wind energy AND solar energy too.

So will the great U.S. boom in clean energy production soon come to an end? Our data is optimistic, but the policy is uncertain.

Jaylen Brown is launching his own sports brand thanks to Kobe Bryant

Published

NBA champion Jaylen Brown did the other of most superstars once they were offered a giant contract. He turned down the offer, but as a substitute decided to start his own brand, crediting the thought to the late Kobe Bryant.

In an exclusive interview with and , a Boston Celtics player discussed his latest enterprise, 741, a footwear and sports brand. After meeting with several firms and never feeling the offers thrown at him, Brown announced that he followed the trail that the nice Kobe planned. The Lakers legend was planning to start his own sports company, so he decided to do the identical.

After turning down $50 million in sponsorship deals, he launched 741 in September.

“Honestly, I got the thought from Kobe (Bryant), rest in peace. Before his death, he planned to launch his own shoe brand, sign contracts with athletes and offer them higher deals and percentages. I remember reading an article about it and pondering it was bullshit. I analyzed my own experiences of working for big corporations and the way they value your creativity and also you. I’ve tried every brand and none of them stood out. Everyone approaches things the identical way. I used to be on the lookout for a brand of the long run, not a brand of the past. I could not find it so I had to start.

Brown also stated that he also helped design products for his line. Outside of design, he said that creating 741 allowed him to explore his creativity.

“I designed all the pieces myself. I used to be just on the factory in South Korea, on the road, ensuring all the pieces was done the way in which I believed it must be. I’ve done probably close to $50 million value of deals (from other brands) to start something on my own. And it wasn’t because I didn’t like the cash they were offering. It’s because these contracts pigeonholed me and didn’t allow me to be creative.

Brown also said he didn’t want to force anything when it comes to brand promotion. He favors a slow-build approach and admitted that “it doesn’t have to be the hottest brand on the street tomorrow.”

The next president will play a key role in shaping US trade policy – here’s what voters need to know

Published

on

By

From the ports of Los Angeles to the cornfields of Iowa, U.S. international trade policy is a force shaping the lives of each American. With the November 2024 presidential election approaching, discussing trade policy will not be just an educational exercise – it’s a civic responsibility.

as economistI even have spent years studying this topic. Trade policy has a huge impact on the best way industries operatefrom production locations to competitive dynamics. These changes impact on a regular basis life, from the associated fee of your morning coffee to job security in your area people.

And since the president has broad control over trade policy, each presidential election is a referendum on the difficulty.

The two most up-to-date administrations – President Donald Trump and Vice President Mike Pence from 2017 to 2021, and President Joe Biden and Vice President Kamala Harris from 2021 to present – ​​have taken very different approaches to trade policy. The contrast shows how the president’s economic philosophy can reshape the country’s global business strategy.

Both Trump and Harris will be on the ballot in November. Harris is Biden’s trade policy is anticipated to proceed if he wins. This comparison provides insight into how the next U.S. president will manage trade.

2017–2021: Trump and Pence on trade

During his time in office, Trump pursued a protectionist trade agenda.

Protectionism refers to government policies that restrict international trade to profit domestic industries. These measures include tariffs – taxes on imported goods – quotas and regulations that make imports costlier.

One of the Trumps first official acts was withdrawal from the Trans-Pacific Partnership, a colossal 12-nation pact that might cover 40% of world production. His decision cost America each access to lucrative Asian markets and a powerful counterweight to China’s economic influence.

Closer to home, Trump renegotiated the North American Free Trade Agreement (NAFTA). United States-Mexico-Canada Agreementtightening regulations for automotive manufacturers. Effect? However, the remuneration of employees in the automotive industry and vehicle prices for American consumers increased, it hardly stimulated any additional domestic automotive production.

Trump also introduced tariffs trade war with China and the European Union, claiming that it might solve unfair practices and reduce the US trade deficit. This strategy, nonetheless, triggered retaliatory tariffs that resulted in higher consumer prices and job losses in American industries depending on imported components. While some sectors have benefited from this approach, U.S. farmers have suffered from export losses, requiring government subsidies.

Trump and his latest running mate, J.D. Vance, have signaled their intention to revive their “America First” trade strategy. Their campaign platform calls for large tariffs, including: general rate of 10% on all goods and more aggressive 60% customs duty aimed specifically at Chinese products.

2021-today: Biden and Harris on trade

In turn, the Biden-Harris administration has adopted a multilateral approach, emphasizing cooperation between countries.

Administration kept most of Trump’s tariffs on Chinese goods in place and part for importing steel and aluminum from other countries. However, they’ve reframed the measures under: wider push stop climate change and protect staff’ rights.

The administration has also launched initiatives equivalent to An Indo-Pacific economic framework for prosperityor IPEF, signaling a return to Obama-era trade strategies that prioritize regional partnerships in the Pacific. IPEF goals to strengthen economic ties with Asian countries by coordinating policies to increase supply chain resilience and promote clean energy, relatively than focusing solely on tariff reductions.

The Biden-Harris approach emphasizes international cooperation while valuing domestic job creation, particularly in the clean energy and manufacturing sectors. However, lots of Trump’s tariffs on Chinese goods, steel and aluminum have been maintained costs high for some US businesses and consumers.

Building on Biden administration policies, Harris’ campaign has signaled that its goal is to protect lower- and middle-income households from latest tariffs this might raise prices while maintaining a tough stance on China through existing tariffs and trade restrictions.

Presidential powers and influence on trade

The president plays key role in determining US trade policy.

The president can negotiate international trade agreements, although Congress must approve them to grow to be law. The executive branch also controls tariffs; under laws equivalent to the Trade Act of 1974, the president can impose them without the consent of Congress.

In addition, the president can declare a nationwide trade emergency, appoint trade representatives, issue executive orders to administer federal trade policy, and impose sanctions that may affect global trade dynamics.

Free trade agreements can boost exports and promote economic growth, but they may displace some staff. However, import tariffs protect some domestic industries, but raise prices for American consumers. Studies show that tariffs imposed under Trump and continued by Biden have led to higher prices, reduced production and declining employment, harming US economy.

Trade policy also affects diplomatic relations and global supply chains. So when voters review candidates’ trade policy positions, they need to look beyond the bits they hear. Understanding how each approach affects labor markets, consumer prices and global competitiveness will help voters solid informed votes that align with their vision for the country’s future.

In the world of trading, every vote counts.
