Q:なんでマイク積んでないの？ WHY NO MICROPHONE??? A:フェニックスには積んでたけどつまんなかったから。 We took a microphone on the Phoenix Mars Lander, and we turned it on but essentially heard nothing (white noise) so it was never released. We don't really need it for any experiments.
Q:せっかく太陽光発電じゃないんだからライト積もうぜライト Does Curiosity have any increased capacity for operating during the Martian night due to it's lack of reliance on solar power? Did you put lights on it? A:ライトはなし。夜は充電してる There are no lights on the Rover. It utilizes the night time to recharge the batteries to drive and explore during the day to take advantage of the day time. Q:でももし火星生物が夜行性だったら？ but what if the life-form only comes out at night... A:ファックだな。 Well fuck. -NASA
Q:なんかかっこいいトリビアおしえて whats one cool trivia fact about curiosity that everybody should know? A:レーザーがついてて岩を蒸発させちゃうぞ Its got a friggin' laser on its head, that can VAPORIZE rocks!
Q:火薬いっぱい使ってるみたいだけどあぶなくないの？ @Rob Zimmerman. It seems there was a lot of pyro devices on curiosity, is that now a mature technology enough so you can pile it without adding too much risks ? Just curious, actually I cannot remember ever having heard of a pyro device with malfunction. A:日々訓練し経験を積んでいるであります These devices are considered very reliable and are used on many spacecraft (NASA and commercial). Curiosity did have a lot of devices, but there was also a lot of redundancy built into the firing system. Many of the devices used on Curiosity had been used successfully on Sprit and Opportunity and Pathfinder, so there was a lot of previous experience here at JPL.
Not all of the pyros were for EDL - we actually had to fire off a set several hours after landing to deploy some of our surface hardware. Testing the pyro system was a pretty big task - if any of them had been mismapped it could have been a bad day for the mission. Getting the timing right was also a challenging task for the EDL team. So in addition to the reliability of the device itself, we had to make sure we were firing the right device at the right time. Thanks for the question! - RMZ
