YOU ARE going to ENTERthe 217 00:08:39,318 --> 00:08:41,854 surface you need to know how to 218 00:08:41,854 --> 00:08:43,422 interact with the regolith. 219 00:08:43,422 --> 00:08:45,858 They have micro gravity levels 220 00:08:45,858 --> 00:08:46,459 of gravity. 221 00:08:46,459 --> 00:08:47,927 This is what you find on the 222 00:08:47,927 --> 00:08:49,729 space station as well. 223 00:08:49,729 --> 00:08:51,464 There are four experiments and 224 00:08:51,464 --> 00:08:54,033 each is a tube about the size of 225 00:08:54,033 --> 00:08:59,071 a pringles can. 226 00:08:59,071 --> 00:09:00,840 The main piece of data we are 227 00:09:00,840 --> 00:09:02,308 getting is the movement of the 228 00:09:02,308 --> 00:09:03,309 particles. 229 00:09:03,309 --> 00:09:10,750 A camera LOOKING at each tube. 230 00:09:10,750 --> 00:09:12,985 We are LOOKING at the long-term 231 00:09:12,985 --> 00:09:15,955 effects of micro gravity. 232 00:09:15,955 --> 00:09:17,623 Something we have on ASTEROID 233 00:09:17,623 --> 00:09:21,027 system vacuum am we want to 234 00:09:21,027 --> 00:09:22,628 EXPOSE them to the vacuum of 235 00:09:22,628 --> 00:09:23,796 space and have our facility 236 00:09:23,796 --> 00:09:27,600 hooked up to a port to space. 237 00:09:27,600 --> 00:09:30,169 The idea is it will be open to 238 00:09:30,169 --> 00:09:36,042 other investigate, CAsass 2, 3, 239 00:09:36,042 --> 00:09:38,344 7 and they will do regolith and 240 00:09:38,344 --> 00:09:41,080 granular material 241 00:09:41,080 --> 00:09:41,547 investigations. 242 00:09:41,547 --> 00:09:44,150 We think it is a good place to 243 00:09:44,150 --> 00:09:46,185 explore regolith and are excited 244 00:09:46,185 --> 00:09:47,653 for what it will bring to 245 00:09:47,653 --> 00:09:56,595 RESEARCHers in the future. 246 00:09:56,595 --> 00:10:03,302 >> Part of the science mission 247 00:10:03,302 --> 00:10:03,836 of the international space 248 00:10:03,836 --> 00:10:07,807 station to take use of 249 00:10:07,807 --> 00:10:11,243 weightlessness for example the 250 00:10:11,243 --> 00:10:13,446 station is home to a threed 251 00:10:13,446 --> 00:10:15,181 printer that can make things and 252 00:10:15,181 --> 00:10:19,218 then recycle them and 3d print 253 00:10:19,218 --> 00:10:21,220 new things using the same 254 00:10:21,220 --> 00:10:25,925 plastic. 255 00:10:25,925 --> 00:10:31,430 >> The refabricater. 256 00:10:31,430 --> 00:10:36,202 PRESENTED by science at NASA. 257 00:10:36,202 --> 00:10:42,942 While 3d printer is technology 258 00:10:42,942 --> 00:10:45,778 people are familiar with, there 259 00:10:45,778 --> 00:10:48,147 one on the iss unlike anything 260 00:10:48,147 --> 00:10:49,882 currently found on earth. 261 00:10:49,882 --> 00:10:51,417 It's known as the refab 262 00:10:51,417 --> 00:10:58,758 riicator, a HYBRID 3d printer 263 00:10:58,758 --> 00:11:03,329 that can recycle its material to 264 00:11:03,329 --> 00:11:11,437 make new things. 265 00:11:11,437 --> 00:11:16,175 NASA's manufacturing manager 266 00:11:16,175 --> 00:11:19,011 says recyclers on earth grind 267 00:11:19,011 --> 00:11:21,280 plastic pellets to create their 268 00:11:21,280 --> 00:11:21,547 products. 269 00:11:21,547 --> 00:11:24,316 But that grinding creates 270 00:11:24,316 --> 00:11:26,052 material shear that prevents you 271 00:11:26,052 --> 00:11:28,421 from reusing it again. 272 00:11:28,421 --> 00:11:29,955 It's no longer strong enough. 273 00:11:29,955 --> 00:11:31,090 For this technology 274 00:11:31,090 --> 00:11:34,193 demonstration the COMPANY 275 00:11:34,193 --> 00:11:36,062 developed a novel RECYCLING 276 00:11:36,062 --> 00:11:38,130 process that doesn't require 277 00:11:38,130 --> 00:11:39,799 grinding and that allows us to 278 00:11:39,799 --> 00:11:41,934 recycle the plastic multiple 279 00:11:41,934 --> 00:11:43,302 times. 280 00:11:43,302 --> 00:11:47,373 The ability to reuse the plastic 281 00:11:47,373 --> 00:11:49,308 over and over again is essential 282 00:11:49,308 --> 00:11:52,745 for long-term space EXPLORATION. 283 00:11:52,745 --> 00:11:54,613 They say we can replace a lot of 284 00:11:54,613 --> 00:11:58,084 the things we need when we orbit 285 00:11:58,084 --> 00:11:59,318 above earth. 286 00:11:59,318 --> 00:12:01,654 But in deep space you don't have 287 00:12:01,654 --> 00:12:03,789 the option you have to have the 288 00:12:03,789 --> 00:12:04,924 ability to make all the parts 289 00:12:04,924 --> 00:12:06,592 you might need and without 290 00:12:06,592 --> 00:12:10,830 having a large STOCKPILE of 291 00:12:10,830 --> 00:12:11,831 extra materials. 292 00:12:11,831 --> 00:12:13,599 It can even recycle plastic 293 00:12:13,599 --> 00:12:16,102 ITEMs not normally ASSOCIATed 294 00:12:16,102 --> 00:12:18,938 with earth bound 3d printers. 295 00:12:18,938 --> 00:12:20,239 Almost all of the materials 296 00:12:20,239 --> 00:12:21,607 delivered to the station are 297 00:12:21,607 --> 00:12:23,576 packed using foam or plastic 298 00:12:23,576 --> 00:12:24,577 bags. 299 00:12:24,577 --> 00:12:25,978 Both can be loaded into the 300 00:12:25,978 --> 00:12:33,085 refabricators to create a eating 301 00:12:33,085 --> 00:12:35,754 utensil or custom made wrench. 302 00:12:35,754 --> 00:12:38,124 That limits the Amount of back 303 00:12:38,124 --> 00:12:40,559 up materials you need to take 304 00:12:40,559 --> 00:12:40,860 with you. 305 00:12:40,860 --> 00:12:43,295 After all, in space, space is at 306 00:12:43,295 --> 00:12:45,030 a premium. 307 00:12:45,030 --> 00:12:51,570 The refabricator will be two 308 00:12:51,570 --> 00:12:59,111 face, they will perform seven 309 00:12:59,111 --> 00:13:01,413 cycles of printing and 310 00:13:01,413 --> 00:13:02,715 RECYCLING. 311 00:13:02,715 --> 00:13:04,250 They will be sent back to earth 312 00:13:04,250 --> 00:13:05,885 for testing and analysis to 313 00:13:05,885 --> 00:13:07,052 determine the EFFECTs of 314 00:13:07,052 --> 00:13:08,754 repeated RECYCLING on the 315 00:13:08,754 --> 00:13:11,590 material properties of the 316 00:13:11,590 --> 00:13:13,459 plastic. 317 00:13:13,459 --> 00:13:15,427 He notes I'm very excited about 318 00:13:15,427 --> 00:13:16,862 the technology in space and back 319 00:13:16,862 --> 00:13:17,596 on earth. 320 00:13:17,596 --> 00:13:19,398 I can envision a day where you 321 00:13:19,398 --> 00:13:21,167 go to the grocery store and drop 322 00:13:21,167 --> 00:13:24,236 your water bottles and plastic 323 00:13:24,236 --> 00:13:26,572 into a refabricator and select
