ATK and NASA ground test their SLS-bound five segment motor
NASA and Alliant Techsystems Inc. (ATK) have conducted a full-scale test of a five-segment solid rocket motor – designated Development Motor-3 (DM-3) – at their test facility in Promontory, on Thursday. The configuration is being tested ahead of a potential role with the Space Launch System (SLS), which would utilize two of the boosters during…

Preliminary NASA plan shows Evolved SLS vehicle is 21 years away
A new schedule, created by NASA, has provided a “preliminary, budget restricted” manifest which places the first flight of the fully evolved Space Launch System (SLS) in the year 2032. The information includes details on the chosen configuration and hardware, but provides a depressing schedule, with a flight rate of just one mission per year,…

STS-134 IFA Review: SRBs and RSRMs Perform Admirably
A critical step in the process of clearing STS-135/Atlantis and her systems for flight has been completed in the form of the In-Flight Anomaly Review (IFA Review) for the previous program flight: STS-134/Endeavour. Particularly, Endeavour’s booster rockets were shown to have performed excellently during the May 2011 retirement flight of OV-105, with only one outstanding…

Boosters providing solid swansong – STS-132 IFA notes excellent performance
As the era of large Solid Rocket Boosters (SRBs) for NASA launch vehicles appears to be drawing to a close, the performance of STS-132’s booster set was recorded as excellent at the In Flight Anomaly Review (IFA). In total, zero IFAs were recorded on the Reusable Solid Rocket Motors (RSRMs) – with only four minor…
