STS-132 begins countdown – Exceptional STS-131 SRB/RSRM performance
As the countdown begins for STS-132, mission managers are continuing to review the status of Atlantis’ hardware, using the baseline of the Flight Readiness Reviews (FRRs). In particular, certification of the STS-132 SRBs and RSRMs for flight was aided by the clean performance of both SRBs/RSRMs on STS-131 – with only one SRB IFA (In-Flight…

STS-131: SRB flight rationale gained following gyro test failure
With Discovery’s payload now installed into the orbiter’s Payload Bay, all eyes are on Friday’s Agency Flight Readiness Review (FRR). Several items of interest are under review, all of which have flight rationale decisions to allow STS-131 to launch on April 5. One item of interest with the Solid Rocket Boosters (SRBs) already has flight…

Shuttle Boosters to sport APU fuel pump safety redesign from STS-134
A redesign to the Solid Rocket Booster (SRB) Thrust Vector Control (TVC) Auxiliary Power Unit (APU) fuel pump will be implemented on STS-134 and STS-133 – currently the final two “scheduled” shuttle flights. The redesign will eliminate the highest – although extremely unlikely to occur – “critical 1” failure scenario, which holds the potential of…

Shuttle Program assesses SRB and RSRM Readiness for STS-130
With just under one week to go before the opening launch attempt for Space Shuttle Endeavour and the STS-130 crew, the Flight Readiness Reviews (FRR) have thoroughly reviewed all open and nonconformance outstanding issues with the Solid Rocket Boosters (SRBs) and Reusable Solid Rocket Motors (RSRMs) ahead of the first shuttle mission of the year.…

IFA Review reveals solid performance of STS-129 SRBs and Main Engines
Capping off a highly successful year for the Space Shuttle Program, the STS-129 flight of Atlantis last month has undergone its final, official post-flight assessment: the all-important In-Flight Anomaly (IFA) review. In all, STS-129 was a clean flight, particularly for the vehicle’s Solid Rocket Boosters (SRBs) and Space Shuttle Main Engines (SSMEs). Solid Rocket Booster…

ATK class STS-129 booster motor performance as excellent
Shuttle managers have concluded the key review of STS-129’s mission, in turn providing a baseline for STS-130’s Flight Readiness Reviews (FRRs). The STS-129 IFA (In Flight Anomaly) review provided an in-depth post flight overview of all shuttle hardware, from the orbiter, to the External Tank, Space Shuttle Main Engines, and boosters – the latter of…

Ares I-X launches – managers claim successful test flight
Ares I-X has launched on the second attempt at 11:30am Eastern, and although the First Stage and the Upper Stage Simulator (USS) appeared to recontact after separation (later confirmed that no recontact took place) – managers are claiming the flight to be a success. Sources also claim one of the FS’ parachutes failed, with the booster splashing down with two working…

Discovery completes dramatic rollout – Unique SRB repairs to take place at Pad
With around three weeks until the launch of STS-128, Discovery has finally arrived at Pad 39A, following a dramatic 10 hour-plus rollout on Tuesday. Once at the pad, engineers will incorporate around a week’s worth of changeouts associated with the left Solid Rocket Booster (SRB), following issues with a Check Valve Filter Assembly (CVFA) –…

STS-127 heads toward June 13 – SRB modifications identified during SSP FRR
NASA officials have cleared Space Shuttle Endeavour for launch on June 13 at 7:17a.m. This mission, the STS-127/2J/A flight, will complete assembly of the Japanese Kibo Laboratory complex during the 16-day journey to space. With this approval for flight comes one of the final steps of flight rationale for Endeavour’s Reusable Solid Rocket Motors (RSRMs)…
