“Staying within the Box” on AIM (James Russell III)
The development of a satellite mission comes with many challenges even when everything develops as expected. Virtually always, however, the expected does not occur. Instrument sensitivities do not materialize as planned; pointing systems underperform; interactions among the payload, spacecraft, and the launch vehicle create vibration loads that threaten the integrity of the observatory; and looming […]
(Preview) Anne Caraccio: Where I Want to Be
As the Space Shuttle Program comes to a close, Anne Caraccio, chemical engineer at Kennedy Space Center, shares her story about how she came to work in the space program and what it means to her as a young professional at NASA. She spoke to an audience of Apollo and Shuttle era engineers at the […]
Spotlight on Lessons Learned: Button Battery Power Supply Issue
An issue with a button battery holder appears to be the cause of an unplanned reset of the Real-Time Clock on the International Space Station Urine Processing Assembly.
Spotlight on Lessons Learned: Cable Harness Wiring and Connector Anomalies Caused by Induced Damage in Human Spaceflight Vehicles
NASA has discovered wiring damage issues in every crewed vehicle system, but early indications suggest the new generation of vehicles appears to benefit from more simplified designs and lower technician traffic during integration.
Spotlight on Lessons Learned: Electrical Short Circuits due to Tin Whiskers
An investigation into the cause of intermittent electrical shorts on the Cassini space probe over a six-year period determined they were most likely due to the presence of tin whiskers.
Spotlight on Lessons Learned: End-to-End Redundancy Analysis
Redundancy and failure analysis should extend beyond end items and the subsystem under design and consider potential failure scenarios for all relevant interfacing subsystems.
Spotlight on Lessons Learned: Incorporating Human Factors from the Beginning of a Program/Project
Employing qualified human factors personnel on a design team from the start of a program or project has proven to be successful and effective.
Spotlight on Lessons Learned: Open-Source and Commercial Web Software Vulnerabilities
Projects that use commercial web software should take proactive measures to mitigate IT security risks.
Spotlight on Lessons Learned: Orbiting Carbon Observatory Launch Vehicle Mishap Investigation Results
Failure of a launch vehicle payload fairing to separate during ascent resulted in the loss of the Orbiting Carbon Observatory satellite mission.
