A NASA T-38 training jet is seen as it flies over Washington, DC, Thursday, April 5, 2012. NASA, in cooperation with the Federal Aviation Administration, conducted training and photographic flights over the DC metropolitan area. T-38 aircraft have been used for astronaut training for more than 30 years as they allow pilots and mission specialists to think quickly in changing situations, experiences astronauts say are critical to practicing for the rigors of spaceflight.

Pyrovalve Booster Interface Temperature Measurement

Benjamin Gonzalez, Jacobs Scientist (seated) shows close-ups of post-firing PCAs to project leader, Steve McDougle (left), and assessment lead, Regor Saulsberry. Problem: The Mars Science Laboratory (MSL) Project is using pyrovalves with stainless steel primer chamber assemblies with a “V” channel shape (V-PCA) rather than the heritage aluminum design with a "Y" channel shape (Y-PCA).  The design was changed to reduce flame channel melting/erosion, eliminate potential obstructions at the channel intersection, and reduce variability.  Read more...

Icing Research Tunnel Force Measurement System Evaluation

Problem: GRC’s Icing Research Tunnel (IRT) is one of NASA’s unique aerodynamic test facilities.  It is one of the largest icing wind tunnels in the world and is constantly in high demand due to this unique capability. One of the tunnel's main features is a large external balance and turntable system.  The tunnel needs to update this force measurement system (FMS) to increase the force and moment measurement accuracy and to improve facility throughput.  This FMS was designed and built in the early 1980s by civil servants who have since retired and GRC no longer has in-house knowledge of how best to upgrade the system.  The NESC was requested to assess the current system, develop new concepts if required, and develop cost estimates and specifications for any suggested upgrades.  Read more...

NASA's Apollo 13 was slated to be the United States' third lunar landing mission. It launched April 11, 1970, at 2:13 p.m. EST from Launch Pad 39A in Florida. From left to right are mission commander Jim Lovell, command module pilot John Swigert and lunar module pilot Fred W. Haise. The mission was aborted after the service module oxygen tank ruptured. Still, the mission was classified as a "successful failure" because of the experience gained in rescuing the crew. As the crew finished a 49-minute TV broadcast showing how comfortably they lived and worked in weightlessness on the evening of April 13, Lovell finished the interview stating, "This is the crew of Apollo 13 wishing everybody there a nice evening, and we're just about ready to close out our inspection of Aquarius and get back for a pleasant evening in Odyssey. Good night." Nine minutes later, oxygen tank No. 2 blew up, causing the No. 1 tank to also fail. The command module's normal supply of electricity, light and water was lost. The crew was about 200,000 miles from Earth. After an intensive investigation, the Apollo 13 Accident Review Board identified the cause of the explosion. In 1965, the command mudule had undergone many improvements that included raising the permissible voltage to the heaters in the oxygen tanks from 28 to 65 volts DC. Unfortunately, the thermostatic switches on these heaters weren't modified to suit the change. During one final test on the launch pad, the heaters were on for a long period of time. This subjected the wiring in the vicinity of the heaters to very high temperatures (1,000 degrees F), which were subsequently shown to have severely degraded the Teflon insulation. The thermostatic switches started to open while powered by 65 volts DC and were probably welded shut. Furthermore, other warning signs during testing went unheeded and the tank, damaged from eight hours of overheating, was a potential bomb the next time it was filled with oxygen. That bomb exploded on April 13, 1970 -- 200,000 miles from Earth. The Apollo 13 crew safely landed in the Pacific on April 17, 1970. Image Credit: NASA
