They fly out of Spaceport America in New Mexico, which was built just for commercial spaceflight. The facility has areas for passenger prep and mission control.
Virgin Gal
American space companies have built some seriously powerful rockets, from SpaceX’s Falcon series to Blue Origin’s upcoming heavy-lift vehicles. These launch systems use new tech like 3D printing and reusable parts to cut costs and boost launch frequency.
SpaceX’s Falcon 9 sits at the top of the rocket game right now. This two-stage vehicle changed everything with its reusable first stage, which lands itself after each launch.
Nine Merlin engines power the first stage. After delivering its payload, the booster flies back and lands on a concrete pad or a droneship at sea.
Key Falcon 9 Specs:
Falcon Heavy is basically three Falcon 9 boosters strapped together. The center core links to two side boosters, making 27 engines at liftoff.
This beast handles missions that Falcon 9 just can’t. It can lift massive satellites and send probes to other planets.
Both side boosters land back at Cape Canaveral in a pretty cool synchronized show. The center core sometimes returns too, depending on the mission.
Falcon Heavy supports national security launches and NASA’s deep space exploration efforts. The reusable design keeps costs lower than you’d expect for such a big rocket.
Starship is SpaceX’s next-gen launch system built for Mars and Moon missions. It has two stages: the Super Heavy booster and the Starship spacecraft, both designed for full reusability.
Super Heavy runs on 33 Raptor engines using methane and liquid oxygen. The upper Starship stage hauls crew and cargo on long trips. Both stages come back to Earth for another flight.
SpaceX wants Starship to work almost like an airline, with quick turnarounds. They even plan to use robotic arms on the launch tower to catch the vehicles as they land.
Starship Features:
NASA picked Starship for its Artemis Moon landings. SpaceX tests the vehicle at its Texas site and has already completed several orbital test flights.
Blue Origin’s New Glenn rocket goes after the heavy-lift market, aiming for reliability and reusability. Named for astronaut John Glenn, it uses seven BE-4 engines in the first stage.
Standing 98 meters tall, New Glenn can send big payloads to a range of orbits. Its reusable first stage lands on a ship at sea, borrowing a page from SpaceX.
The rocket features a roomy 7-meter payload fairing for large satellites and spacecraft. It’s built for both commercial and government missions.
Blue Origin wants high flight rates and consistent performance. They plan to build the rocket at scale using modern techniques.
New Glenn Highlights:
The rocket wrapped up development and started flying in 2025. Blue Origin sees New Glenn as a direct rival to Falcon Heavy for big payloads.
United Launch Alliance (ULA) runs two main rockets from different eras. Atlas V has been America’s most reliable launcher for 20 years, with a flawless track record.
Atlas V’s modular design lets it fit all kinds of missions. You can add different numbers of solid boosters to match the payload.
This rocket launched major NASA missions—think Mars rovers and Jupiter probes. It also carries Boeing’s Starliner crew capsule to the ISS.
Vulcan Centaur is ULA’s replacement for Atlas V, bringing in modern tech and lower costs. It runs on two BE-4 engines from Blue Origin and uses advanced manufacturing.
Vulcan Centaur Upgrades:
ULA uses 3D printing and other new methods to make Vulcan more affordable. They designed it to compete with newer commercial rockets while keeping reliability high.
Vulcan handles big national security launches and NASA’s top science missions. It started flying in 2024 after lots of testing.
American space companies have built cutting-edge spacecraft that safely carry crew and cargo to space. These vehicles range from cargo haulers for the space station to capsules that carry tourists to the edge of space.
SpaceX’s Dragon capsule stands out as one of the most successful commercial spacecraft flying today. The crew version hauls up to seven astronauts to the International Space Station, while the cargo variant brings supplies and experiments.
Dragon relies on a heat shield to keep the crew safe during high-speed reentry. SuperDraco thrusters handle emergency escapes, pulling the crew away from a failing rocket in just seconds.
Key Dragon Specifications:
Since 2020, Dragon has flown dozens of crewed missions. NASA astronauts regularly ride Dragon to reach the space station.
Commercial space tourists have booked private orbital missions aboard Dragon, too.
Dragon swaps out traditional switches and buttons for touchscreen controls. The capsule docks automatically with the space station, relying on sensors and computers to line everything up.
Northrop Grumman built Cygnus to deliver cargo to the International Space Station on regular supply runs. Unlike Dragon, Cygnus burns up during reentry and can’t return anything to Earth.
Cygnus hauls up to 8,000 pounds of supplies, experiments, and gear. It launches on rockets like Antares and Atlas V.
After docking, crew members unload the cargo over several weeks.
The flexible design lets Cygnus carry different cargo setups for every mission. It can fit large items that other vehicles just can’t handle.
Scientists use Cygnus to send lab equipment and research samples to orbit.
Cygnus Mission Profile:
Cygnus uses its own propulsion system for orbital maneuvers. Ground controllers can tweak Cygnus’s path during approach if needed.
Sierra Space’s Dream Chaser spaceplane brings something different to the table: it can land on runways, not just splash down in the ocean. The vehicle looks a bit like a mini space shuttle and touches down on regular airport runways anywhere in the world.
Dream Chaser will start cargo missions to the International Space Station soon. The spaceplane can bring back sensitive experiments and cargo that need a gentle landing, which capsules can’t always guarantee.
The lifting body design creates lift without classic wings. Dream Chaser can glide to a landing even if its engines quit.
Pilots can control the landing approach just like they would with a regular plane.
Dream Chaser Advantages:
Sierra Space also plans a crew version of Dream Chaser for future flights. The spaceplane could carry up to seven people to a space station and bring them back safely to a runway.
Virgin Galactic’s SpaceShipTwo takes passengers on suborbital flights to experience weightlessness and see the curve of Earth. Instead of launching vertically, SpaceShipTwo drops from a carrier aircraft.
During powered flight, SpaceShipTwo hits speeds over three times the speed of sound. Passengers get several minutes of weightlessness at the top of their flight path.
Then the craft glides down to a runway landing, much like a regular airplane.
The cabin has big windows, so everyone gets a clear view of space and Earth. Six passenger seats recline to help folks enjoy the weightless moments safely.
Virgin Galactic has already flown paying customers on multiple crewed flights. Each ticket costs hundreds of thousands of dollars.
The company operates out of Spaceport America in New Mexico.
SpaceShipTwo flies with two pilots and can’t reach orbit like Dragon or other spacecraft. Each mission lasts about 90 minutes from takeoff to landing.
American space companies keep leading the way in deploying massive satellite networks that connect millions of people around the globe. SpaceX holds the top spot with its Starlink constellation, while Amazon and others prepare their own networks powered by advanced electric propulsion.
SpaceX runs the world’s largest satellite constellation, with over 5,000 active satellites in low Earth orbit. The company wants to reach 12,000 satellites in phase one and could eventually deploy up to 42,000.
Each Starlink satellite uses phased array antennas for precise beam steering. The satellites talk to each other using inter-satellite laser links, which means they don’t always need ground stations in remote places.
SpaceX launches batches of 20-60 satellites at a time with Falcon 9 rockets. Reusable rockets make these launches cheaper and faster.
Starlink satellites orbit between 340 and 570 kilometers above Earth. This low altitude keeps internet latency at 20-50 milliseconds, way better than the 600+ milliseconds of old-school geostationary satellites.
The constellation now serves over 2 million customers in more than 60 countries. Users connect with small dish terminals that automatically track the satellites overhead.
Amazon’s Project Kuiper is Starlink’s biggest competitor in the works, with 3,236 satellites planned. Amazon got regulatory approval and started testing prototypes in 2024.
OneWeb runs 648 satellites focused on business and government users. The UK-based company partners with American firms for ground infrastructure and user terminals.
Boeing works on satellite technology for several constellation projects. The company also provides launch services and handles on-orbit operations for commercial networks.
Electric propulsion powers most new constellation satellites. These ion thrusters use 90% less fuel than chemical rockets and allow for precise orbital changes.
American companies team up with NASA through unfunded Space Act Agreements. Seven companies are working with NASA right now to move commercial space forward and cut government costs.
Mass production lets companies build hundreds of satellites every year. SpaceX manufactures six satellites a day at its Redmond facility, using automated assembly lines.
Rideshare missions help cut costs by launching multiple customer satellites together. Companies pay $1-5 million per satellite instead of $50+ million for a dedicated launch.
Satellite constellations need complex orbital coordination to avoid collisions. Automated systems track more than 34,000 objects in space and constantly calculate collision risks.
New satellites come with propulsion systems for end-of-life disposal. Satellites deorbit themselves within 5-25 years to help keep space cleaner.
Ground networks keep constellations running through gateway stations and user terminals. American companies operate thousands of ground sites to connect satellite data to fiber internet.
American companies are building the backbone of space commerce with advanced logistics networks and orbital platforms. These firms work on everything from robotic servicing vehicles to persistent manufacturing hubs that operate beyond Earth.
Modern space logistics companies create supply chains that mirror those on Earth. Rogue Space Systems leads the charge with their Waypoint platforms, which act as orbital industrial parks for multiple payloads.
The company’s Orblock intermodal containers standardize payload integration across missions. This system cuts down on custom engineering and speeds up deployment.
Orbot robotic vehicles handle transport, refueling, and inspections between platforms. These automated systems take care of routine orbital tasks without human intervention.
Sierra Space builds commercial space travel infrastructure from its headquarters in Colorado. Their focus is on creating sustainable transport networks for civil, commercial, and national security needs.
NASA’s Space Superhighway concept lays out three main parts: regional orbital hubs, sustainable transport networks, and Earth-to-orbit logistics. This setup supports satellite servicing, Earth science, and space domain awareness.
Ground infrastructure firms provide the support systems that make orbital operations possible. They handle mission control, data processing, and communication links between Earth and space.
In-space manufacturing turns orbit into a production environment that takes full advantage of microgravity. Companies can make semiconductors, fiber optics, and pharmaceuticals with quality you just can’t get on Earth.
Varda Space Industries pioneered automated manufacturing platforms that operate in orbit and send products back to Earth. Their systems don’t need a permanent crew during production.
Manufacturing platforms use special containers to keep tight control over temperature, pressure, and contamination during production.
Biotech companies use orbital labs to grow protein crystals and develop new medicines. Microgravity lets them form bigger, more perfect crystals than Earth labs can manage.
The vacuum and temperature extremes of space help companies create ultra-pure metals and composite materials for aerospace and electronics.

Research containers provide controlled environments for each experiment. Standardized power, data, and thermal management systems let researchers focus on science instead of engineering headaches.
Pharmaceutical research in microgravity leads to better drug formulations and new treatment options. Companies study protein interactions and cell behavior without gravity getting in the way.
Agricultural research looks at how plants grow and develop in space. These studies help both Earth farming and future space colonies.
Materials research digs into alloy formation, crystal growth, and manufacturing processes that benefit from weightlessness. The results often improve how things get made back on Earth.
Hardware and software hosting services let researchers run experiments without needing their own satellites. This approach cuts costs and speeds up timelines for academic and commercial projects.
American companies are taking the lead on ambitious missions to the Moon and beyond. Several firms are building lunar landers for NASA’s Artemis program, and private ventures are eyeing asteroids for mining and deep space exploration.
Intuitive Machines became the first private company to land on the Moon with their Nova-C lander in February 2024. The Houston-based team works under NASA’s Commercial Lunar Payload Services (CLPS) program.
Astrobotic Technology in Pittsburgh develops the Peregrine lunar lander series. NASA awarded them $34.6 million to create LunaGrid-Lite, a power system that distributes electricity across lunar surfaces using cables.
Astrobotic’s CubeRover technology unreels over half a mile of high-voltage power lines. This system connects power sources to habitats and work areas on the Moon.
Lunar Outpost focuses on lunar rovers and surface operations gear. They design vehicles that can cross the Moon’s tough terrain for long missions.
NASA’s CLPS program hires several companies to deliver scientific instruments and supplies to the lunar surface. These missions lay the groundwork for human landings under Artemis.
AstroForge leads the way in American asteroid mining, with plans to extract platinum and other metals from near-Earth asteroids. The company tests refining tech in space before picking specific targets.
Their two-phase strategy includes demo missions first, then commercial extraction. AstroForge wants to process materials in space instead of hauling them back to Earth.
Blue Origin got $34.7 million from NASA to develop lunar resource utilization systems. Their tech extracts materials from lunar soil to make solar cells and wiring.
Deep space missions need advanced propulsion and life support. Companies like Zeno Power Systems develop radioisotope power supplies using Americium-241 for long missions beyond the reach of solar power.
These ventures are after both scientific exploration and commercial resource extraction in the asteroid belt and outer solar system.
NASA’s Commercial Crew Program really shook up American human spaceflight. By teaming up with SpaceX and Boeing, they finally ended nine years of relying on Russian Soyuz vehicles.
These partnerships now keep crew rotations to the International Space Station running smoothly. They’ve also opened the door for regular civilian space travel and all sorts of new commercial ventures.
NASA’s Commercial Crew Program stands out as the biggest change in American human spaceflight since the Space Shuttle days. Instead of just doing it all themselves, NASA now works with private companies to get astronauts to the ISS.
This approach has changed how the U.S. thinks about sending people into space.
SpaceX really leads the pack with its Crew Dragon spacecraft. In May 2020, they launched their first astronauts—Bob Behnken and Doug Hurley—up to the ISS.
Since then, SpaceX has pulled off several crew rotations. That’s a pretty solid track record for commercial human spaceflight.
Boeing built the CST-100 Starliner as the program’s second spacecraft. Starliner ran into some technical and software issues, but finally flew its first crewed test in June 2024.
Unlike Dragon, Starliner lands on solid ground, not in the ocean.
Key Program Benefits:
The program uses fixed-price contracts, so companies eat any cost overruns. Boeing got $4.2 billion, SpaceX $2.6 billion for development and initial missions.
The International Space Station is still the main destination for commercial crew flights. American companies now ferry astronauts from several countries, which really strengthens those international ties in low Earth orbit.
Right now, ISS operations include seven crew members from Expedition 73. Commander Takuya Onishi leads the team, with flight engineers from NASA, Roscosmos, and JAXA.
These crews are busy with research in a bunch of science fields.
Commercial crew vehicles like Dragon and Starliner dock at the Harmony module using automated systems. They can stay attached for up to 210 days, serving as extra crew quarters or emergency rides home if needed.
Mission rotations keep things running up there. Crews usually spend about six months on the ISS before heading back.
New astronauts overlap with leaving crews for a few days, just to make sure everything transitions smoothly.
The partnership model lets Russian Soyuz keep flying while American companies handle routine rotations. Having both options adds redundancy and keeps international cooperation strong, even if politics get messy back on Earth.
Station crews focus on science, tech demos, and maintenance. Reliable rides from commercial providers mean research and crew planning are more consistent.
Commercial spaceflight companies have started offering rides to regular folks, not just government astronauts. Space tourism seems like the next big step, giving private citizens a shot at orbital adventures.
SpaceX kicked off civilian orbital missions with Inspiration4 in September 2021. That three-day flight took four private citizens higher than the ISS.
SpaceX has since flown more private missions, even taking paying customers to the ISS.
Virgin Galactic runs suborbital flights from New Mexico, letting passengers float in weightlessness for a few minutes. Blue Origin’s New Shepard does similar suborbital trips from Texas with automated capsules.
Going to orbit costs way more than suborbital flights. Private ISS trips via SpaceX run tens of millions per seat, while suborbital rides are in the hundreds of thousands to a few million dollars.
Several companies want to build space hotels and commercial stations for tourists. These could offer longer stays and cut reliance on government-run stations.
Medical requirements for space tourists depend on the mission. Suborbital flights need just basic health checks, but orbital trips require serious training and medical tests, a lot like the pros.
Small launch companies go after payloads up to 1,500 kg to low Earth orbit. This opens up new opportunities for satellite operators and government missions.
The U.S. Space Force recently brought in more contractors through the Orbital Services Program-4, letting companies like Blue Origin and Stoke Space compete for small satellite launches.
Rocket Lab runs launches from New Zealand and Virginia. They specialize in small satellite launches with their Electron rocket.
Since 2017, Rocket Lab has finished over 40 missions, making them the top small launch provider outside of SpaceX.
The Electron rocket can carry up to 300 kg to sun-synchronous orbit. It uses battery-powered turbopumps instead of the usual gas generators, making it lighter and more efficient for smaller payloads.
Rocket Lab’s Neutron rocket is their move into medium-lift territory. This reusable rocket will go head-to-head with Falcon 9 for bigger payloads and satellite constellations.
They also offer end-to-end space services, from satellite manufacturing to mission ops and space systems for both commercial and government clients.

American space companies are changing how rockets get built and powered. 3D printing and advanced electric systems are making things faster, cheaper, and just plain better for commercial spaceflight.
Relativity Space took 3D printing to the next level with the Terran 1 rocket. They print about 85% of the rocket using their own machines and metal alloys.
That cuts parts from 100,000 to just 1,000. Manufacturing time shrinks from years to just months.
Ursa Major prints entire rocket engines with additive manufacturing. Their Hadley engine uses 3D printing to create complex shapes you can’t make the old-fashioned way.
This lets them quickly prototype and test new engines—sometimes in just 30 days from design to firing.
Aerojet Rocketdyne teamed up with Firefly Aerospace to blend additive manufacturing know-how with rocket production. This partnership speeds up the path from digital design to flight hardware.
Material advances now include special metal powders and ceramics. These can handle the crazy heat and pressure inside a rocket engine.
Electric propulsion uses electricity to push propellant particles really fast. That means ten times better fuel efficiency than chemical rockets.
Hall effect thrusters have taken over the commercial satellite market. They work by creating plasma and shooting ions out using electric fields.
Gilmour Space Technologies is building hybrid rocket engines that mix solid and liquid propellants. It’s a nice balance—better control than solid rockets, but still pretty simple.
Ion drives move deep space probes and satellites. They run for months, slowly building up serious speed.
Solar electric propulsion pairs ion engines with big solar arrays. Spacecraft can reach far-off planets using just sunlight for power.
Advanced chemical propulsion includes oxygen-rich staged combustion engines. These burn fuel and oxidizer in stages, squeezing out more performance.
American space companies lean hard on strategic partnerships with government agencies, especially NASA. The agency provides technical expertise and funding, and these collaborations spark competition and innovation while keeping costs down for everyone.
NASA’s Collaborations for Commercial Space Capabilities-2 (CCSC-2) teams up with seven big American space companies through unfunded Space Act Agreements. These deals let companies tap into NASA’s technical know-how, data, and experience, but they have to pay their own way.
