direct

DIRECT was a late-2000s proposed alternative super heavy lift launch vehicle architecture supporting NASA's Vision for Space Exploration that would replace the space agency's planned Ares I and Ares V rockets with a family of Shuttle-Derived Launch Vehicles named "Jupiter".DIRECT was advocated by a group of space enthusiasts who asserted that they represented a broader team of dozens of NASA and space industry engineers who actively worked on the proposal on an anonymous, voluntary basis in their spare time. In September 2008, the DIRECT Team was said to consist of 69 members, 62 of whom were NASA engineers, NASA-contractor engineers, and managers from the Constellation Program. The small number of non-NASA members of the team publicly represented the group.The project name "DIRECT" referred to a philosophy of maximizing the re-use of hardware and facilities already in place for the Space Shuttle program (STS), hence a "direct" transition. The DIRECT Team asserted that using this approach to develop and operate a family of high-commonality rockets would reduce costs and the gap between retirement of the Space Shuttle and the first launch of Orion, shorten schedules, and simplify technical requirements for future US human space efforts.Three major versions of the DIRECT proposal were released with the last, Version 3.0, unveiled in May 2009. On 17 June 2009, the group presented its proposal at a public hearing of the Review of U.S. Human Space Flight Plans Committee, a panel reviewing US space efforts, in Washington D.C.With the October 11th signing of the NASA Authorization Act of 2010 (S. 3729) by President Obama mandating work on the Space Launch System Heavy Lift Launch Vehicle, the DIRECT Team declared their effort a success and disbanded. Some members subsequently announced the formation of a new space technology company: C-Star Aerospace, LLC.

    Mira 8 now discontinued. Is there a direct replacement?

    Is there a direct drop-in replacement for a Mira 8 exposed shower mixer valve? My father-in-law says it was fitted 30 years ago. Spares no longer available. The critical dimension is the gap between the nuts that attach to each side of the valve body. Has anyone done this replacement?

    Hi, I have a hot water cylinder which feeds 3 outlets (kitchen sink, basin in bathroom & bathtap) which has never had very good pressure (probably because of the set-up) but last year got so feeble that a guy suggested fitting a pump alongside the cylinder.
