The U.S. Space Force (USSF) is the newest branch of the U.S. military, created in 2019 to protect American interests in space. It tracks satellites and debris, secures vital communications like GPS, defends against hostile actions using electronic and cyber tools, and develops future space defense technologies—all while working alongside civilian agencies such as NASA.

Summary

  • The USSF launched as a separate service in 2019
  • It safeguards U.S. satellites and other space assets
  • Teams monitor orbiting objects to prevent collisions
  • It runs and protects the GPS navigation system
  • Military communications rely on its satellite fleets
  • Defensive operations “blind and deafen” enemy satellites
  • Cyber units target threats to space systems on Earth
  • It shares tracking data with global partners
  • Budget has grown past NASA’s, fueling new projects
  • It avoids physical attacks that would create dangerous debris
  • Collaboration with NASA boosts both science and security

How the U.S. Space Force Safeguards America’s Satellites

The Origins of the Space Force

In December 2019, the U.S. stood up the Space Force as its sixth military branch. Leaders saw space as a critical domain for both security and national power. Before that, the Air Force managed space duties. Congress passed the Space Force act to make domain awareness and defense its sole mission (About Us).

Mission and Responsibilities

The USSF has four main roles. It operates military and navigation satellites. It tracks objects in orbit, like debris and other nations’ spacecraft. It secures critical communications channels. And it innovates new defenses, including cyber and electronic tools. Together, these keep U.S. systems running and safe.

Tracking Space Objects

Space Force teams use ground stations and space sensors to watch more than 27,000 objects in Earth orbit. They share data with the Joint Space Operations Center to predict and prevent collisions. This work protects active satellites and helps astronauts stay safe on missions.

Communications and Navigation

USSF manages satellite networks that carry military calls, data links, and missile warnings. It also keeps the GPS constellation healthy. Everyday devices—cars, planes, and phones—depend on those signals. Teams replace old satellites and fix jamming attempts so services stay reliable.

Space Operations: Defense and Offense

Space can be a silent battlefield. Instead of shooting at satellites, the Space Force uses electronic warfare to blind or deafen hostile systems. Cyber units on Earth target networks controlling enemy spacecraft. All tactics stay classified to protect U.S. methods and assets.

“There are a few different ways the Space Force carries out its mission,” said Space Insider. “One is simply watching and waiting, using both ground- and space-based systems to track objects in orbit.”

Organization and Teams

The Space Force includes field commands focused on operations, systems, training, and acquisition. Each command has experts in satellites, cyber, and engineering who work together to meet mission goals.

Command Name Mission Focus
Space Operations Command Satellite control and domain awareness
Space Systems Command R&D, acquisition, and launch support
Space Training Command Education in orbital mechanics, cyber
Space Acquisition Building and testing new spacecraft

Training and Personnel

The USSF draws talent from the Air Force, Army, and civilian experts. Recruits learn at special schools—some at the Space Systems Command—covering orbital physics, satellite ops, and cyber warfare. Regular exercises simulate satellite threats and debris tracking so teams can respond fast and smart.

Budget and Growth

Since its creation, the Space Force budget has steadily risen—surpassing NASA’s alone some years—to fund satellites, ground stations, and research labs.

Year USSF Budget (USD) NASA Budget (USD)
2019 15 billion 22.6 billion
2020 18 billion 23 billion
2021 21 billion 24 billion
2022 24 billion 25 billion
2023 26 billion 25.5 billion

Collaboration with NASA

Though NASA focuses on science—like the Perseverance rover’s Mars mission—the agencies share tech and data. NASA builds rockets for exploration, while the Space Force adapts similar systems for defense. Working together saves money and boosts safety in space (NASA, Perseverance Rover).

Future Plans

Looking ahead, USSF will field new satellites with advanced sensors and test on-orbit servicing to fix or refuel aging spacecraft. It plans laser-based communications for faster data. Partnerships with allies through the Combined Space Operations Center aim to share tracking data. New units will watch space weather to guard against solar storms.

Challenges Ahead

Space is crowded, and debris grows every year. The Space Force must find better ways to clear and track junk. International laws for space conflict remain vague. Tech must evolve quickly to meet fast-moving threats in orbit.

Facts

  • The Space Force’s logo is the Delta, Globe, and Star motif.
  • Its motto, “Semper Supra,” means “Always Above.”
  • General John W. Raymond is its first Chief of Space Operations.
  • The Space Medal rewards exceptional service.
  • Uniforms feature unique grey digital patterns.

China Launches Three-Satellite Constellation for Earth-Moon Communications
The Technology and Engineering Center for Space Utilization (CSU) of the Chinese Academy of Sciences (CAS) gave this picture. It shows three satellites working together. They are in a special path around the Earth and moon, called the Distant Retrograde Orbit (DRO).

Introduction

China’s recent success in launching its three-satellite constellation marks a revolutionary step in space exploration. This mission, executed in the vast Earth-moon region, demonstrates how the use of a Distant Retrograde Orbit (DRO) can address long-standing challenges in deep-space communication and exploration. With a focus on reducing energy consumption and operational costs, the project has already inspired the global space community by proving that innovative technologies can overcome severe technical obstacles.

The mission involved three different satellites—DRO-A, DRO-B, and DRO-L—each playing a distinct role in advancing our understanding of space dynamics. DRO-L was the first to be launched into a sun-synchronous orbit, where it began critical experiments. DRO-A and DRO-B were launched later from the Xichang Satellite Launch Center in China’s Sichuan Province. Despite an initial setback caused by an anomaly in the carrier rocket’s upper stage, an intense rescue operation ensured that all satellites eventually reached their designated orbits.

Mission Overview and Technological Innovations

The breakthrough in this mission lies in its innovative use of the Distant Retrograde Orbit (DRO). This orbit type, unusual compared to traditional satellite paths, allows spacecraft to operate with minimal energy expenditure. The stability offered by DRO creates a natural hub in space that connects Earth to the moon and even further into deep space. The savings in fuel and operational costs are substantial. This leap in efficiency provides enormous potential for future missions that may include crewed space exploration and advanced scientific research.

Below is a table presenting key details of each satellite:

Satellite Orbit Type Mission Role Launch Date
DRO-A Distant Retrograde Orbit (DRO) Experimentation and autonomous navigation March 13, 2024
DRO-B Maneuver Orbits in Earth-Moon Space Inter-satellite communication and measurement March 13, 2024
DRO-L Near-Earth Orbit Initial experiments and data collection February 3, 2024

The use of DRO represents a pioneering strategy in space engineering. Traditional satellites often require frequent adjustments to maintain their orbits, leading to higher fuel consumption and increased operational risk. By contrast, the DRO method harnesses gravitational forces in both the Earth and moon systems, providing stability over extended periods while requiring only minimal propulsion adjustments. This method is critical in advancing the next generation of space exploration missions.

Technical Details and Overcoming Challenges

During the initial phase of the mission, the satellites encountered significant challenges. An anomaly in the carrier rocket’s upper stage resulted in DRO-A and DRO-B deviating from their planned trajectories. In what many described as a “life-or-death” situation, the satellite team acted swiftly. They executed a series of emergency maneuvers under extreme conditions, successfully reorienting the satellites and guiding them back onto their intended paths after a journey covering 8.5 million kilometers.

The mission’s success was not merely a triumph of engineering under pressure but also a testament to the resilience of the space team. The autonomous navigation systems on board, alongside the real-time adjustments made during the rescue operation, demonstrated that even unforeseen complications could be managed effectively. By establishing inter-satellite and satellite-to-ground communication links using K-band microwave technology, the team ensured that critical data was relayed over distances as vast as 1.17 million kilometers. This technological breakthrough not only confirms the feasibility of DRO but also opens new pathways for cost-effective deep-space monitoring and data collection.

Breakthrough and Future Opportunities

The successful networking of the constellation represents a remarkable breakthrough in satellite technology. It is a prime example of how advanced engineering and innovative problem solving can converge to overcome challenges in the rigorous field of space exploration. The critical achievement of establishing high-precision inter-satellite links has reduced the reliance on prolonged ground-based tracking systems. Instead of two full days of tracking, the new system accomplishes equivalent orbit determination in just three hours.

This dramatic improvement in efficiency is expected to spur a new era of low-cost, autonomous deep-space exploration. Scientists and engineers are now able to plan more ambitious missions, with the possibility of deploying larger constellations to monitor vast areas of space. Future research will likely expand into fields such as quantum mechanics, atomic physics, and the investigation of the lunar environment, leveraging the constant stability provided by DRO.

The mission’s impact is already being felt in international space research circles. By demonstrating a reliable, cost-effective method for long-duration space travel, China’s accomplishments serve as a catalyst for collaborative projects and potential international partnerships. The lessons learned from this mission could lead to innovations that benefit not only the field of space exploration but also terrestrial technologies in communication and navigation.

Below is a timeline summarizing the key events of the mission:

Event Date Description
DRO-L Launch Feb 3, 2024 Satellite entered a sun-synchronous orbit and began executing planned scientific tests.
DRO-A/B Launch March 13, 2024 Satellites launched from Xichang Satellite Launch Center, Sichuan Province, China.
Orbit Correction Post-launch Emergency maneuvers reestablished the proper trajectory after a launch anomaly.
Successful Separation Aug 28, 2024 DRO-A and DRO-B were separated and initiated inter-satellite communication experiments.

International Implications and Future Research

The implications of this mission extend far beyond China’s borders. The successful demonstration of a low-energy, high-efficiency satellite constellation provides a model that other nations and private companies can emulate. As global interest in space exploration continues to grow, the DRO approach presents a promising avenue for reducing launch costs and the operational complexities of extended missions.

This achievement inspires hope for more extensive scientific collaborations and innovative projects that harness similar technologies. The possibility of creating a network of satellites that communicate and operate autonomously could transform how deep-space missions are planned and executed. By laying the groundwork for autonomous orbit determination and low-cost deep-space travel, China has set a new benchmark in the field.

In addition, the successful mission significantly contributes to the understanding of the lunar space environment. It offers scientists valuable data that can lead to breakthroughs in our understanding of gravitational dynamics, cosmic radiation, and the potential for human habitation beyond Earth. The knowledge gathered from this project is expected to influence future research in astronomy, physics, and engineering, driving further technological advances in these areas.

Facts

Innovative Terraforming Techniques to Rapidly Warm Mars for Human Habitation

Innovative Terraforming Techniques to Rapidly Warm Mars for Human Habitation

Terraforming Mars to create a more Earth-like environment is a long-term goal of space exploration. One of the first critical steps is warming the Martian atmosphere, which could eventually lead to a thicker atmosphere and melting of the polar caps. A recent study proposes a novel method of warming Mars using nanoscale aerosols made of graphene and aluminum. This method, if proven effective, could be a significant first step in making Mars more hospitable for human life.

Summary

  • Recent studies suggest using graphene and aluminum aerosols to warm Mars’ atmosphere.
  • This is one of the first proposed methods of terraforming Mars.
  • Warming Mars’ atmosphere will help melt the polar ice caps and release water vapor.
  • The melting ice will also release carbon dioxide, further warming the planet.
  • Proposed techniques for increasing Mars’ temperature include adding CFCs, methane, or ammonia to the atmosphere.
  • Warming the atmosphere will thicken it, bringing it closer to Earth-like conditions.
  • Melting the ice caps could result in 300 millibars of atmospheric pressure, enabling humans to survive without a pressure suit, though still needing warm clothing.
  • Researchers from Aeolis Research, NASA’s Jet Propulsion Laboratory, and other institutions have contributed to the study.
  • The University of Chicago’s Edwin S. Kite led the groundbreaking research.
  • The next step in the process involves creating bioregenerative life support systems (BLSS) for humans to live sustainably on Mars.
  • Various theories and proposals have been made for warming Mars, with each method requiring massive resources.
  • Researchers agree that the process of terraforming Mars will take many years and require innovative technologies.

Innovative Terraforming Techniques to Rapidly Warm Mars for Human Habitation

Introduction

Multiple plans exist to explore Mars in the coming decades using robotic and crewed missions. The ultimate goal of these missions is to determine whether human beings could actually live there someday. This requires access to building materials, water, cutting-edge manufacturing technology, and closed-loop habitation systems with bioregenerative life support systems (BLSS). Basically, future settlers will need to create conditions that mimic Earth’s self-sustaining ecological systems – essentially, we need to “take Earth with us” to other planets.

In the long term, these efforts could extend to the entire planet in an effort to make Mars “Earth-like.” This process is known as “terraforming,” and many proposals have been made over the past 50 years. In a recent study, an interdisciplinary team presented a novel way to warm up Mars’ atmosphere using nanoscale aerosols of graphene and aluminum. Their findings indicate that Mars’ atmospheric dynamics and radiative processes make engineered aerosol warming possible, which could constitute the first step in terraforming the planet.

Research Overview

Edwin S. Kite, an associate professor at the University of Chicago and a member of the Curiosity rover’s science team, led the study. He was joined by researchers from the planetary science research Aeolis Research, Northwestern University, the University of Central Florida, the MIT Haystack Observatory, the European Centre for Medium-Range Weather Forecasts (ECMWF), and NASA’s Jet Propulsion Laboratory. The paper describing their findings was presented at the 2025 Lunar and Planetary Science Conference.

The study suggests using nanoscale aerosols made of graphene and aluminum to warm Mars’ atmosphere. Graphene is a single layer of carbon atoms arranged in a two-dimensional lattice, and it is known for its ability to absorb sunlight and heat up when exposed to solar radiation. By dispersing these aerosols into the Martian atmosphere, they could absorb more sunlight, thus increasing the temperature of the atmosphere.

This study, presented at the 2025 Lunar and Planetary Science Conference, is one of the first to propose this method. It highlights how Mars’ unique atmospheric dynamics could make engineered aerosol warming feasible. The concept of using aerosols in this way could offer a scalable and efficient method to kickstart the terraforming process on Mars.

Steps to Terraform Mars

When it comes right down to it, the process of terraforming Mars consists of three interconnected steps:

1. Warming the Atmosphere

The first step, as we’ve discussed, is to increase the temperature of Mars’ atmosphere. Warming the planet would lead to the melting of ice caps and the release of gases like carbon dioxide, further enhancing the greenhouse effect. This is crucial for jumpstarting the terraforming process.

2. Thickening the Atmosphere

Once the temperature increases, the next goal is to thicken the atmosphere to a point where it can support human life. Mars’ current atmospheric pressure is too low for humans to survive without spacesuits. Scientists aim to increase the atmospheric pressure to at least 300 millibars, or 30% of Earth’s sea-level pressure. This would allow humans to walk outside with just warm clothing, though they would still need oxygen tanks.

3. Melting the Polar Caps and Permafrost

The final step in the terraforming process would be to melt Mars’ polar ice caps and permafrost. As the ice melts, it will release water into the atmosphere and onto the surface. Additionally, dry ice (frozen carbon dioxide) in the ice caps will sublimate, releasing carbon dioxide and further thickening the atmosphere.

Potential Methods for Warming Mars

Many methods have been suggested over the years for warming Mars. These include:

  • Low albedo materials: Spreading dark-colored materials over the polar caps to absorb more sunlight.
  • Chlorofluorocarbons (CFCs): Filling the atmosphere with chemicals that trap heat.
  • Methane or ammonia: Introducing gases that would create a stronger greenhouse effect.
  • Carbon dioxide harvesting: Importing carbon dioxide from other planets, like Venus, to thicken Mars’ atmosphere.

The Importance of Warming Mars’ Atmosphere

Mars has a thin atmosphere, mainly composed of carbon dioxide, with very little oxygen or nitrogen like Earth’s. This makes the planet cold, with an average surface temperature of about -60°C. If we are to consider human colonization of Mars, this cold atmosphere presents a significant obstacle. A warmer atmosphere would allow for liquid water to exist on the surface, which is essential for human life.

The warming process would have multiple stages. First, scientists need to increase the temperature of the atmosphere. This could eventually lead to the melting of the polar ice caps, releasing water and carbon dioxide. Once the atmosphere thickens, the pressure would increase, making it more hospitable for human life. But how can this be achieved? Several proposals have emerged over the years, each with its own set of challenges and benefits.

The quest to increase Mars’ temperature is a complex and multifaceted challenge that involves innovative scientific research and technological advancements. As we continue to explore Mars and develop our understanding of its environment, the dream of terraforming the planet may one day become a reality.

How to Power CubeSats Using Deep Learning: Innovative Energy Solutions for Space

CubeSat missions face significant power management challenges, but by integrating deep learning techniques—specifically a deep feedforward neural network linked with traditional control systems—the efficiency of Maximum Power Point Tracking (MPPT) can be greatly enhanced. This innovation not only boosts overall power generation but also reduces fluctuations that may harm sensitive onboard electronics.

Summary

  • CubeSats are small, modular satellites with strict power limitations.
  • Power is primarily generated through solar panels, but environmental factors cause fluctuations.
  • Traditional MPPT algorithms such as Perturb and Observe, Incremental Conductance, and Particle Swarm Optimization offer 88–94% efficiency.
  • A new approach using deep learning (Deep Feedforward Neural Network) integrated with a proportional-integral controller reaches up to 97% efficiency.
  • The algorithm optimizes solar orientation and minimizes power ripple, ensuring stable operations.
  • Despite being computationally intensive, innovative techniques like linear tangents and Neville Interpretation simplify calculations.
  • The deep learning model provides an adaptive solution to unpredictable space conditions.
  • Two comprehensive tables compare CubeSat power system components and MPPT algorithm efficiencies.

Introduction

CubeSats are small, modular spacecraft used for various scientific and commercial missions. Designing a CubeSat involves many challenges, and one of the biggest hurdles is powering the satellite efficiently. CubeSats are typically powered by solar panels that deploy from their structured frame. However, their power generation is affected by environmental conditions such as solar radiation fluctuations and temperature variations.

The power system in a CubeSat must be both reliable and efficient. Traditional methods of power management often struggle to keep up with rapid changes in power output. Recent research has shown that deep learning can be integrated into CubeSat power systems to overcome these challenges. This technology helps optimize the Maximum Power Point Tracking (MPPT) process, which is vital for extracting the most power possible from the solar panels.

Design Challenges for CubeSat Power

CubeSat designers face many tradeoffs when choosing solar panels, batteries, and power converters. The physical limitations of CubeSats mean that there is little room to add extra components. Additionally, the harsh space environment exposes the CubeSat to unpredictable changes in sunlight and temperature, which in turn affect the power available.

Power system faults are a major reason behind CubeSat mission failures. Studies have shown that up to 25% of CubeSat missions fail due to issues with power management. This has driven the need for innovative approaches that can adapt to real-time changes in power conditions. By using deep learning algorithms, engineers can design systems that adjust dynamically, ensuring that CubeSats receive the necessary power even in fluctuating conditions.

Deep Learning in CubeSat Power Systems

Traditional MPPT algorithms such as Perturb and Observe (P&O), Incremental Conductance (InC), and Particle Swarm Optimization (PSO) have proven to be effective in achieving efficiencies ranging from 88% to 94%. However, these methods are not adaptive. Their parameters must be predetermined before launch, which limits their effectiveness in an unpredictable space environment.

To overcome these limitations, researchers have developed a Deep Feedforward Neural Network (DFFNN) that works alongside a standard proportional-integral controller. This combination outperforms conventional MPPT algorithms, achieving an efficiency of about 97% in simulated year-long missions. Although deep learning requires significant computational resources, innovative techniques such as linear tangents and Neville Interpretation simplify the calculations needed to determine the CubeSat’s trajectory and power needs.

CubeSat Component Specifications

The following table outlines some key components used in CubeSat power systems along with their specifications:

Component Description Efficiency
Solar Panels Convert sunlight into electrical power Up to 20%
Batteries Store electrical energy for later use Around 85-90%
MPPT Controllers Optimize power extraction from solar panels 88-97% (depending on algorithm)
Deep Learning Processor Processes data for adaptive power management Enhanced performance

Deep Feedforward Neural Network and MPPT Algorithm

The new algorithm uses deep learning to adjust the MPPT process in real-time. This approach is particularly effective when the CubeSat’s orientation to the Sun is not optimal. The algorithm detects changes in solar radiation and quickly recalculates the ideal angle for the solar panels, ensuring maximum power capture.

The integration of a Deep Feedforward Neural Network (DFFNN) is key to this process. The DFFNN is trained on simulated data from long-term CubeSat missions, allowing it to predict and react to changes in power conditions. By doing so, it not only increases efficiency but also minimizes “power ripple”—sudden changes in voltage or current that can harm the CubeSat’s components.

An additional benefit of this deep learning approach is its ability to lower the computational demands using techniques like linear tangents and Neville Interpretation. These methods break down complex polynomial equations into simpler forms, making real-time calculations more feasible in the limited computing environment of a CubeSat.

MPPT Algorithm Comparison

The table below compares traditional MPPT algorithms with the new deep learning approach:

Algorithm Efficiency Adaptability Computational Demand
Perturb and Observe (P&O) 88% Low Low
Incremental Conductance (InC) 90% Low Moderate
Particle Swarm Optimization 94% Moderate High
Deep Learning DFFNN 97% High High (optimized with new techniques)

The improved efficiency of the deep learning method, even by a small percentage, is significant in the context of CubeSat missions. Every watt counts when space and weight are limited, and these small improvements can ultimately determine mission success.

Benefits for Space Missions

Improving the power efficiency of CubeSats using deep learning has several benefits. Higher efficiency means that CubeSats can perform longer missions and collect more data. Reduced power ripple also leads to less wear and tear on the electronic components, enhancing the overall lifespan of the spacecraft.

The approach also offers flexibility. Instead of having fixed parameters for power management, CubeSats can now adapt to varying conditions in space. This dynamic adaptability increases the reliability of CubeSat missions and can be crucial during critical operations like data collection or scientific experiments.

CubeSat missions have already begun exploring these new technologies. For example, you can learn more about the innovative approach in the Deep Learning-Based MPPT Approach to Enhance CubeSat Power Generation paper. Other exciting missions include a 3U CubeSat designed for asteroid flybys, a CubeSat mission for detecting X-rays from GRBs and black-hole mergers, and the first CubeSat equipped with a Hall-Effect Thruster. Video resources on this topic are available at this link and this link.

Facts

  • CubeSats were first introduced as educational tools but now play a major role in space research.
  • Modern CubeSats can perform complex tasks like Earth observation and scientific experiments.
  • The integration of deep learning in space technology is a relatively new but fast-growing field.
  • Even a small efficiency gain in CubeSat power systems can lead to major improvements in mission outcomes.
  • Innovative algorithms reduce not only power ripple but also the risk of component failure.

SpinLaunch is challenging the long-standing reliance on chemical rockets by developing a kinetic launch system. Instead of burning massive amounts of fuel, the system uses a large vacuum-sealed centrifuge to accelerate satellites and other payloads before hurling them into the upper atmosphere.

The principle behind this approach is not new—medieval trebuchets used similar kinetic energy concepts to launch projectiles. However, modern materials, electronics, and engineering advancements have made it possible to scale this method for space launches.

𝐇𝐨𝐰 𝐒𝐩𝐢𝐧𝐋𝐚𝐮𝐧𝐜𝐡 𝐖𝐨𝐫𝐤𝐬

SpinLaunch’s orbital accelerator is essentially a massive, high-speed spinning arm enclosed in a vacuum chamber. Here’s how it functions:

  • A payload (satellite or spacecraft) is attached to the rotating arm inside the chamber.
  • The system spins the payload at incredible speeds (up to 5000 mph) using electric motors.
  • At the precise moment, the arm releases the payload, flinging it into space.

Unlike rockets, this system does not require staging, meaning there are no parts to be discarded mid-flight.

𝐀𝐝𝐯𝐚𝐧𝐭𝐚𝐠𝐞𝐬 𝐎𝐟 𝐊𝐢𝐧𝐞𝐭𝐢𝐜 𝐋𝐚𝐮𝐧𝐜𝐡𝐞𝐬

  • Lower cost: Fuel is one of the largest expenses in traditional rocket launches. SpinLaunch eliminates this entirely.
  • Eco-friendly: No carbon emissions or fuel combustion reduces environmental damage.
  • High launch frequency: The system can launch satellites multiple times a day without requiring extensive refurbishment.

𝐂𝐡𝐚𝐥𝐥𝐞𝐧𝐠𝐞𝐬 𝐅𝐨𝐫 𝐒𝐩𝐢𝐧𝐋𝐚𝐮𝐧𝐜𝐡

While the idea is promising, several technical hurdles remain:

  • Extreme G-forces: The payload must withstand forces of up to 10,000 Gs, requiring special engineering.
  • Atmospheric resistance: The object must pierce through the lower atmosphere at high speeds.
  • Payload limitations: Currently, only small satellites can be launched, as the system is not designed for human travel.
Low Earth Orbit Tech Giant Catapult Sends Satellites Into Space Without Using Rocket Fuel (2)
SpinLaunch has created a system called the kinetic launch system. This system can send objects into space. The process involves using a large spinning arm. The arm throws objects into the sky at high speeds. This is different from traditional rockets. Rockets use a lot of fuel to escape Earth’s gravity. The kinetic launch system uses less fuel. It relies on spinning energy instead. SpinLaunch is the company that developed this technology. They believe it is a more efficient way to reach space.
