One of the key questions about Blue Origin is whether it will push toward full reusability with New Glenn. In 2021, Ars first reported on an effort codenamed "Project Jarvis" to develop a stainless steel upper stage that could be reused. The company even built a test tank, although the effort was eventually shelved.

Going forward, SpaceX is likely to offer its gigantic Starship rocket as a competitor to New Glenn, and here, the advantage shifts back to SpaceX. Bigger than New Glenn (120 meters tall versus 98) and with a wider faring to encapsulate cargo (9 meters versus 7), SpaceX's Starship will boast a massive payload advantage over Blue Origin's new rocket.
