Jeff Foust writes about the unheralded 25th anniversary of the DC-X flights, and what has happened in the past half decade to see the promise that it offered a quarter of a century ago finally coming to fruition. I attended the 20th anniversary, but the only thing happening this year is a dinner in LA later this month.
I would note, per the criticism of the “purists,” that SSTO is highly overrated. Two-stage systems are much more flexible and efficient, particularly for off-nominal missions (e.g., high inclination or high altitude). SSTO would make sense only for a large traffic model to a single destination, probably equatorial.
