The House Armed Services Committee appears determined to require United Launch Alliance (ULA) to re-engineer its Atlas V booster with a new Aerojet Rocketdyne engine in its first stage even though the launch provider doesn’t really want the motor.

CENTENNIAL, Colo., March 24, 2016 (ULA PR) – United Launch Alliance (ULA) successfully completed the Preliminary Design Review (PDR) for the Vulcan Centaur launch vehicle with dual Blue Origin BE-4 engines. The PDR, a major milestone in development of the Vulcan launch vehicle, confirms that the design meets the requirements for the diverse set of missions it will support. The ULA team will build upon this milestone to refine and test key elements of the design while executing a busy manifest of 14 launches in 2016.

SpaceX’s Philosophy: Reliability Through Continual Upgrades

Remains of a Falcon 9 rocket fall to Earth.

To succeed in the launch business, you need to be very, very good and more than a little bit lucky. Eventually, there comes a day when you are neither.

That is what happened to SpaceX on June 28. A string of 18 successful Falcon 9 launches was snapped as the company’s latest rocket broke up in the clear blues skies over the Atlantic Ocean. A Dragon supply ship headed for the International Space Station was lost, SpaceX’s crowded manifest was thrown into confusion, and the company’s reputation for reliability was shattered.

CENTENNIAL, Colo., June 12, 2013 (ULA PR) —
United Launch Alliance (ULA) successfully completed the Preliminary Design Review (PDR) and initial round of development testing for the Dual Engine Centaur in support of NASA’s Commercial Crew Program.

Under Independent Research and Development (IRAD) funding, ULA is re-establishing the Dual Engine Centaur (DEC) configuration for performance and human space flight safety. Atlas V is capable of flying both a single and dual engine on the Centaur second stage, but most satellite missions require only a single engine due to the powerful capability of the Atlas V booster to loft the payload into orbit.

Major Upgrades Planned for Aging Centaur Upper Stage

The Centaur upper stage, which has been propelling American satellites through space since 1965, is getting a major upgrade that would allow the venerable one-shot booster to perform in a series of new roles.

In the coming decades, upgraded Centaurs will make launching  of spacecraft on Atlas V and Delta IV rockets much less expensive. They could also function as reusable space tugs, orbital fuel depots, and landing vehicles that would transport tons of cargo to and from the Moon, Mars and asteroids.

Xearo

  • Xaero capable of reaching 100,000 feet
  • Next generation beyond Xoie, which won the Lunar Lander Challenge
  • Under flight testing now
  • 88 tether flights
  • 2 successful free flights
  • Installing an aeroshell on Xaero changed flight characteristics
  • “By the time we figured out what was going on, we were 88 tether flights in.”
  • Building a second Xaero within the next few months to do high altitude flights up to 100,000
  • Masten has too many customers for the first Xaero, which will be used for low-altitude flights
