Small Satellite Launchers Poised for Big 2020 

Written by Thomas Burghardt

In 2019, American companies reached crucial milestones on the path towards launching small satellites. Firefly Aerospace and Virgin Orbit both secured partnerships and accomplished test objectives ahead of their respective rockets’ first flights this year. Concurrently, Rocket Lab improved its launch cadence and began evolving their Electron rocket as they look towards expanding their capabilities in 2020. 

Firefly Aerospace 

Texas-based Firefly Aerospace is gearing up for the debut of the Alpha rocket, scheduled for the first quarter of 2020. The mission will lift off from SLC-2W at Vandenberg Air Force Base in California, the pad which formerly supported the United Launch Alliance’s Delta II rocket.

The final step in Alpha’s development before launch is currently underway, with a complete first stage installed on Test Stand 2 for qualification testing. The integrated stage, including four of Firefly’s Reaver engines, will complete a hotfire testing series concluding with multiple full mission duty cycle tests lasting 165 seconds each.

Check out the Firefly Alpha engine bay! There are 4 Reaver engines on the first stage which generate 165,500 lbf of thrust, allowing Alpha to deliver 1,000 kg of payload to low LEO and 630 kg to 500 km SSO. #Firefly #MakingSpaceForEveryone #FullAttack! pic.twitter.com/QbR8ykWxTT

 In order to complete the home stretch of Alpha’s development, Firefly is partnering with the experienced aerospace company Aerojet Rocketdyne. Through this partnership, Firefly will gain expertise in additive manufacturing for Reaver engine production. Aerojet Rocketdyne will also influence changes to the first and second stage engines for Alpha Block 2, an upgraded design that will increase payload performance. Block 2 upgrades are expected to increase the mass Alpha can deliver to Sun Synchronous Orbit from 630 kilograms to 800 kilograms.

Beyond the Alpha rocket, Aerojet Rocketdyne will also work with Firefly on the Orbital Transfer Vehicle and the larger Beta launch vehicle. The Beta rocket, initially planned to be a tri-core design, will now feature a larger single core. The stage will be powered by the AR1 engine that Aerojet Rocketdyne originally designed to power ULA’s Vulcan rocket, prior to the selection of Blue Origin’s BE-4 instead.

Firefly is also partnering with international companies for both launch vehicles and spacecraft. Switzerland-based RUAG Space will supply the payload adapter for Firefly launch vehicles. RUAG is an experienced aerospace supplier, already providing payload adapters for Ariane 5, Atlas V, Delta IV, Proton, Soyuz, and Antares launch vehicles.

For missions bound for cislunar space, Firefly has partnered with Israel Aerospace Industries, agreeing to cooperate on lunar lander technology based on the Beresheet spacecraft. Both companies will collaborate to develop an American version of the lander, named Genesis. The spacecraft will be used to compete for mission contracts under NASA’s Commercial Lunar Payload Services (CLPS) program. Firefly says the first flight of Genesis will occur in Q4 of 2021. 

Virgin Orbit 

In Mojave, California, Virgin Orbit is also preparing to launch an orbital rocket for the first time. After being shipped from the factory in Long Beach, the first orbital LauncherOne rocket has completed propellant load cycles and pressurization testing.

Prior to the first attempt to reach orbit, the rocket will be mated to the Boeing 747 carrier aircraft Cosmic Girl, on the taxiway at Mojave Air and Spaceport. A taxi test with the rocket on board, as well as a captive carry flight test, will be conducted in January. These tests will precede a demonstration launch in the coming weeks.

Looking to the future, Virgin Orbit has also pursued new launch sites and new destinations for its customers. The UK Space Agency awarded Virgin Orbit £7.35 million ($9.5 million) in order to enable LauncherOne missions from Spaceport Cornwall, at Cornwall Airport Newquay in England. Funding is to be used to develop and manufacture launch operations support systems, with the goal of the first launch from Cornwall no earlier than Q4 of 2021.

Once off the ground, LauncherOne payloads may be destined for beyond low Earth orbit. As part of a consortium between Virgin Orbit, SatRevolution, and Polish universities, between one and three launches will deliver spacecraft as small as 50 kilograms to Mars. The first LauncherOne mission with this interplanetary architecture is scheduled for no earlier than 2022.

The spacecraft will be designed and manufactured by SatRevolution, a Polish nanosatellite manufacturer. SatRevolution launched Poland’s first commercial nanosatellite aboard the NG-11 mission to the International Space Station in April 2019. The satellite was delivered aboard the Northrop Grumman Cygnus cargo spacecraft, and released from the station in July 2019.

The partnership is part of a new offering from Virgin Orbit which adds a third stage within the rocket’s payload fairing, providing the performance needed to deliver payloads to higher Earth orbits, the Moon, or interplanetary destinations. 

Rocket Lab 

The most experienced small satellite launch provider, Rocket Lab, is still conducting tests and reaching milestones of their own. The tenth launch of the Electron rocket was successful, including a successful guided reentry of the first stage, an important step towards recovery and reuse.

Aboard flight ten was also a new Automated Flight Termination System (AFTS), a system now only used by Rocket Lab and SpaceX. The system replaces human-in-the-loop flight termination systems, and aims to reduce turnaround time between missions.

Flight ten did, and all future Electron missions will, exclusively utilize AFTS. The successful debut on flight ten followed four flights where both AFTS and human-in-the-loop FTS systems were present.

Another Rocket Lab debut will come in Q2 2020 when the first mission from Launch Complex 2 (LC-2) lifts off. The new pad at the Mid-Atlantic Regional Spaceport, NASA Wallops Flight Facility in Wallops Island, Virginia, will support a dedicated mission for the United States Air Force’s Space Test Program. The STP-27RM mission will consist of a single research and development satellite.

Rocket Lab has also broken ground on a third launch pad, LC-1B, adjacent to LC-1 on the Mahia Peninsula of New Zealand. Both new pads will support Rocket Lab’s goal of increasing launch frequency, with LC-1B planned to support missions within just days of each other.

Comentário: Pois é leitor, enquanto isso no Brasil o caminho continua por velhas práticas que poderão nos levar ainda mais ao fundo no poço, portanto é tremendamente preocupante. Vou deixar uma mensagem aqui aos burrocratas de Platão e aos que se utilizam desta ignorância para colher frutos econômicos ou mesmo aqueles que querem atrapalhar o desenvolvimento espacial do país. Demonstrador tecnológico só é um caminho utilizado em tecnologias de vanguarda como as desenvolvidas no IEAv e por motiveis óbvios, e não para foguetes lançadores de satélites convencionais, tecnologia está já dominada há várias décadas. Das três ações crucias e urgentes que o governo deveria ter tomado em 2019 (duas politicas e uma técnica) só uma foi tomada efetivamente e com eficiência, ou seja, a aprovação do Acordo de Salvaguardas Tecnológicas (AST) com os EUA. Já as outras, a transformação do PEB em Programa de Estado e o estabelecimento de um projeto nacional de um lançador de pequenos satélites competitivo se valendo de quem realmente pode chegar a este objetivo em tempo recorde, infelizmente não foram estabelecidos, mas sim conversas de bastidores partindo do conceito de se desenvolver demonstradores tecnológicos sem o menor compromisso de serem competitivos, ação que como eu disse não faz sentido nenhum e atrasará ainda mais a nossa entrada no mercado. Já é consenso até mesmo dentro da FAB de que o VLM-1 se sair mesmo do papel não será competitivo, em outras palavras, não passará de um demonstrador tecnológico. Assim sendo, não faz sentido nenhum continuar com isso. A outra opção que o MCTIC parece ter discutido com a empresa Avibras foi a ideia de um lançador baseado no foguete de sondagem VSB-30, mas como esperar que uma empresa que não consegue sequer entregar um motor sólido dentro do prazo e vive solicitando mais dinheiro, possa realizar um projeto de veículo lançador com a eficiência e a rapidez que o país precisa? E olha que eles contam com a ajuda de técnicos tanto do IAE como do DLR, mas mesmo assim o motor em questão, o S-50, continua sem uma solução e o tempo passando. Tá mais que claro que o caminho (modelo) não é esse, e ele já é mais que conhecido e atende pelo nome de “New Space”, hoje só encontrado no país nas startups espaciais. Lamentável!
