A spaceplane breaks barriers, reaching incredible heights and speeds
Dawn Aerospace, based in Christchurch, New Zealand, is making waves in the aerospace industry with its groundbreaking approach to creating a reusable spaceplane. But why should this matter to you? Imagine a future where space travel is as routine and affordable as flying across the country. This is the vision Dawn Aerospace is working towards, and its recent achievements bring us one step closer to that reality.
Major advances in spaceplane technology
Dawn Aerospace’s latest test flight, conducted as part of its Campaign 2-2 development program, saw its uncrewed Mk-II rocket-powered aircraft reach transonic speeds of Mach 0.92 and an altitude of 50,000 feet.
This achievement represents a substantial enhancement in performance, with improvements of three to five times compared to previous metrics. The company is now ready to begin Campaign 2-3 in September, where it hopes to achieve supersonic flight for the first time. The overarching goal is to create a spaceplane that combines the performance of a first-stage rocket with the predictability and rapid turnaround of a conventional aircraft.
Future goals and aspirations
Dawn Aerospace has set ambitious targets for its Mk-II spaceplane. By the end of 2025, the company hopes to climb faster than an F-15, fly higher than a MiG-25 and exceed speeds greater than the SR-71 Blackbird. Additionally, they aspire to be the first vehicle to fly above the Karman line, defined as 62 miles altitude, twice in a single day. Many of these records have stood for over 50 years, highlighting the ambitious nature of their goals.
The company has invested approximately $10 million in the program so far and plans to complete it for under $20 million in total. Dawn Aerospace’s rapid progress through flight testing, compared to other rocket development programs, can be attributed to its core philosophy and design methodology. This approach allows the company to move quickly and confidently through flight tests while minimizing risks.

Resolução comentada
Vamos conferir cada proposição com o texto.
I – Falsa. O Mk-II chegou a Mach 0,92, que é transônico. O voo supersônico é apenas uma meta da Campaign 2-3 ("hopes to achieve supersonic flight for the first time"). Ele ainda não é capaz de voar supersônico.
II – Falsa. "Making waves" é uma expressão idiomática e significa causar impacto, chamar atenção. Não tem relação com ondas artificiais.
III – Verdadeira. O texto diz que a empresa já investiu cerca de US$ 10 milhões e planeja concluir o programa "for under $20 million in total", ou seja, gastar menos de US$ 20 milhões.
IV – Verdadeira. "By the end of 2025, the company hopes to climb faster than an F-15". A proposição diz que isso é o planejado ("is supposed to"), o que confere com o texto.
Só III e IV estão corretas.
Alternativa C.
Pegadinha: A alternativa B engana quem toma "making waves" ao pé da letra; a A engana quem confunde a meta supersônica com algo já alcançado.
Por que as outras alternativas estão erradas
- AA proposição I é falsa: o supersônico é só uma meta futura, o avião atingiu Mach 0,92 (transônico).
- BA proposição II é falsa: "making waves" é expressão idiomática para causar impacto, não ondas artificiais.
- DAmbas são falsas: o voo supersônico ainda não foi alcançado e "making waves" é uma expressão idiomática.
Assunto: Informações explícitas e detalhes.
