Today on their internet site,NASA GRC discretely but firmly claim that they have observed anomalous heat in Palladium-deuterium systems
Tests conducted at NASA Glenn Research Center in 1989 and elsewhere consistently show evidence of anomalous heat during gaseous loading and unloading of deuterium into and out of bulk palladium. At one time called “cold fusion,” now called “low-energy nuclear reactions” (LENR), such effects are now published in peer-reviewed journals and are gaining attention and mainstream respectability. The instrumentation expertise of NASA GRC is applied to improve the diagnostics for investigating the anomalous heat in LENR.

In their sliideshow, they refer to an old report made in 1989 by Fralick&al, but they mostly describe a F&P/Mills cell style experiment made in 1996.
In the slides this paper is presented as inconclusive, yet if you read the conclusion in detal it rather says that "recombination" can be used as an excuse, but that it seems hard to swallow anyway, and that one shoul look further... yet the budget is exhausted...
The gas permeation experiment made in 1989 revealed anomalous heat with Pd+D, unlike Pd+H, but they were only looking for neutrons and classic D+D fusion. Finding no neutrons they did not pursue.“Following the principle of simplest explanation that fits the data on hand, recombination becomes the explanation of choice. But even perfect recombination can not account for all of the apparent excess heat in those Mills cells usually operated in a pulsed current mode and reported to input to the cell.”These cases at least leave the door open to more interesting possibilities. Considering the potential
value of a new energy source it seems worth while to study the Mills type cell in configuration allowing an accurate account for recombination and water loss.
Insufficient resources prevented us from proceeding with a more careful study of the excess heat effect in cell types adapted to bear on specific questions. For example, certain gaseous loading types,such as the D2-Pd transient pressurizing experiments at NASA or the H2-Ni heating experiment at the University of Siena, could avoid the complications of electrolytic cells, while exploring possibilities of high temperature operation and radiation
The report "slept in a drawer", but some get aware of it...
It was already replicated in 2005 by a chinese team, with Dr Liu of Tsinghua University, and collaboration with Infinicon
note that infinicon describe it self as: "INFICON provides world-class instruments for gas analysis, measurement and control."
It was latter replicated by JP Biberian in 2007
Then NASA in 2009 replicated the protocol, using moderns tools, and producing heat .
note that this article tell the story of LENR at NASA, mostly from 2003...
Unlike what I was thinking before, it seems now that the situation was not so clear at NASA until 2003-2009.
It was because of lack of curiosity, lack of budget, that some would put on bad corporate dynamic, conformism, peer pressure, conservative funding... Anyway, NASA later proved it was above the average.
