Pegasus is an air-launched multistage rocket developed by Orbital Sciences Corporation (OSC) and later built and launched by Northrop Grumman. Pegasus is the world's first privately developed orbital launch vehicle. Capable of carrying small payloads of up to 443 kg (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remained active as of 2021. The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 12,000 m (39,000 ft) using a first stage wing and a tail to provide lift and altitude control while in the atmosphere. The first stage does not have a thrust vector control (TVC) system.
UP Aerospace, Inc. is a private spaceflight corporation headquartered in Denver, Colorado. UP Aerospace provides sub-orbital transportation for corporate, military and educational payloads, via their SpaceLoft XL sounding rocket launch vehicles.
The SpaceLoft XL is a sounding rocket developed by private spaceflight company UP Aerospace. The rocket is capable of lofting a 79 lb (36 kg) payload to a sub-orbital trajectory with an apogee of about 71.5 miles (115 km). It travels for approximately 60 seconds to cross the Kármán line. All launches are sub-orbital and do not complete one orbital revolution. Launches are conducted from the company launch facility at Spaceport America in Upham, New Mexico.
Spaceport America, formerly the Southwest Regional Spaceport, is an FAA-licensed spaceport located on 18,000 acres (7,300 ha) of State Trust Land in the Jornada del Muerto desert basin 45 miles (72 km) north of Las Cruces, New Mexico, and 20 miles (32 km) southeast of Truth or Consequences. With Virgin Galactic's launch of the VSS Unity, with three people aboard, on May 22, 2021, New Mexico became the third US state to launch humans into space after California and Florida.
The Zephyr is a series of high-altitude platform station aircraft produced by Airbus. They were designed originally by QinetiQ, a commercial offshoot of the UK Ministry of Defence. In July 2010, the Zephyr 7 flew for 14 days. In March 2013, the project was sold to Airbus Defence and Space. In the summer of 2022, the Zephyr 8/S flew for 64 days.

Rocket Lab USA, Inc. is a publicly traded aerospace manufacturer and launch service provider that operates and launches lightweight Electron orbital rockets used to provide dedicated launch services for small satellites as well as a suborbital variant of Electron called HASTE. The company plans to build a larger Neutron rocket as early as 2025. Electron rockets have launched to orbit 49 times from either Rocket Lab's Launch Complex 1 in New Zealand or at the Mid-Atlantic Regional Spaceport in Wallops Island, Virginia, United States. Rocket Lab has launched one sub-orbital HASTE rocket to date from Wallops Island, Virginia. In addition to the Electron, Neutron, and HASTE launch vehicles, Rocket Lab manufactures and operates spacecraft and is a supplier of satellite components including star trackers, reaction wheels, solar cells and arrays, satellite radios, separation systems, as well as flight and ground software.
LauncherOne was a two-stage orbital launch vehicle developed and flown by Virgin Orbit that had operational flights from 2021 to 2023, after being in development from 2007 to 2020. It was an air-launched rocket, designed to carry smallsat payloads of up to 300 kg (660 lb) into Sun-synchronous orbit (SSO), following air launch from a carrier aircraft at high altitude. The rocket was carried to the upper atmosphere on a modified Boeing 747-400, named Cosmic Girl, and released over ocean. Initial work on the program was done by Virgin Galactic, another Virgin Group subsidiary, before a separate entity — Virgin Orbit — was formed in 2017 to complete development and operate the launch service provider business separately from the passenger-carrying Virgin Galactic business.
Astra Space, Inc., formerly known as Ventions, LLC from 2005 - 2016, is an American space company based in Alameda, California, with facilities in Sunnyvale, California and Atwater, California. The company was initially an aerospace technology research firm that focused on SBIR contracts, developing small rocket engines for use on launch vehicles and satellite propulsion. In 2012, the company shifted to developing launch vehicles and was selected for the DARPA ALASA program, eventually leading to the development and launch of the Astra Rocket series of launch vehicle utilizing both government and private funding after reincorporating itself to Astra Space, Inc. in 2016. The company would have their first successful launch in 2021, nine years after the start of development, after 6 previous failed attempts.
Orbital-2, also known as Orb-2, was the third flight of the Orbital Sciences' uncrewed resupply spacecraft Cygnus, its third flight to the International Space Station, and the fourth launch of the company's Antares launch vehicle. The mission launched from the Mid-Atlantic Regional Spaceport (MARS) on 13 July 2014 at 16:52:14 UTC.
Electron is a two-stage, partially reusable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. Electron services the commercial small satellite launch market. It's the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable, Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has, however, abandoned the idea of catching Electron.
Firefly Alpha is a two-stage orbital expendable small lift launch vehicle developed by the American company Firefly Aerospace to compete in the commercial small satellite launch market. Alpha is intended to provide launch options for both full vehicle and rideshare customers.
Vector-R is a two-stage orbital expendable launch vehicle under development by the American aerospace company Vector Launch to cover the commercial small satellite launch segment (CubeSats). Vector Launch went bankrupt in December 2019 and re-emerged in October 2020. Two prototypes were launched in 2017.
The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by ISRO with payload capacity to deliver 500 kg (1,100 lb) to low Earth orbit or 300 kg (660 lb) to Sun-synchronous orbit for launching small satellites, with the capability to support multiple orbital drop-offs. SSLV is made keeping low cost, low turnaround time in mind with launch-on-demand flexibility under minimal infrastructure requirements.
