All,
Really Sad to see what happened to Genesis. I thought this as one of the neatest mission concepts! In 2001, while working at JPL on the Europa Orbiter Project I worked right around the corner from the guys you're seeing on TV who worked on Genesis and attended the Launch "Party" and Reception at JPL. It was really exciting, for it was the first time I was ever with the people who devoted so much of their time to a project, seeing it with them launch into space. Mr. Sweetnam, Mission Project Manager, always said Hello in the hall, and I believe my only interaction with him was trying to buy one of the neat Genesis Polo Shirts he always was wearing ![]() but I did get some neat stickers! However, when this happened today I immediately recalled a NASA Press Release I Got E-mail Wise about the Mission back in November of '01. Maybe some of you remember it? I was able to dig it up, this is quite suspect. Here's a link to an article on the problem the press release talks about: http://www.space.com/scienceastronom...is_011102.html .. "Genesis Status Report November 5, 2001 Project managers are monitoring the temperature of the battery inside Genesis' sample return capsule to make sure that long-term heating does not impair its performance when the capsule returns to Earth in September 2004. Although the battery is likely to become hotter than originally expected, the flight team has a number of options for managing the battery's temperature, and they do not expect the issue to affect the mission. The mission's science requirements call for 22 months of solar wind particle collection. "In our current plan Genesis will meet and exceed that goal, collecting up to 26 months' worth of solar wind particles," said Chet Sasaki, Genesis project manager at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The temperature of the lithium-dioxide battery is currently at 23 degrees Celsius (73 degrees Fahrenheit), within the range anticipated by spacecraft designers. A radiator device intended to shield the battery is not working as well as expected, however, and the battery is likely to heat up to 42 degrees Celsius (108 degrees Fahrenheit). Mission managers consider this temperature to be within acceptable limits. They note that similar batteries have been maintained at 60 degrees Celsius (140 degrees Fahrenheit) for 15 months without impairing their performance. Ground tests are being conducted on lithium batteries to measure their durability at various temperatures. The Genesis project team has been attempting to bake potential contaminants off the battery's radiator by heating the area. They are doing this with the spacecraft's sample return backshell opened just enough to allow gas trapped inside the capsule to escape, while still avoiding exposure to the Sun." No guarantee this is what caused the problem, but I'm sure this is something the mishap investigation team will thoroughly look into. Anyways, too neat of a mission with Awesome Science not to attempt a redo! Genesis 2 anyone? Regards, Ted A. Nichols II President - ASH www.astrohbg.org |
