[ti:NASA Doctor ‘Holoported’ to Space in Technology Experiment] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]A doctor with the American space agency NASA [00:05.44]has made a virtual visit to the International Space Station (ISS) [00:11.36]after being "holoported" by technology. [00:16.40]Dr. Josef Schmid and several other people [00:20.76]took the virtual trip last October. [00:24.60]NASA recently announced results of the experiment. [00:30.04]The agency said it was the first time [00:34.88]that humans had been "holoported" from Earth to space. [00:40.44]The term holoport is a combination of the words [00:45.60]hologram and teleport. [00:48.92]A hologram is an image produced by a computer and made of light. [00:56.04]Hologram objects appear in a shapely form, [01:00.80]not flat like other images. [01:04.04]Teleport means to travel extraordinarily fast using special technology. [01:11.84]Such technology does not exist, however. [01:16.56]Holoport technology can project 3D models of people in any environment. [01:25.60]This permits people physically present in the environment to see, [01:31.76]hear and interact with the holoported individuals. [01:37.24]The experiment at the ISS involved a computer, [01:42.72]camera and special software developed by NASA [01:47.76]and its industry partner Aexa Aerospace. [01:52.28]Special headsets enable people involved [01:56.44]to interact with one another as if they were in the same shared space. [02:02.76]The camera used was the Kinect model, [02:06.52]made by American software company Microsoft. [02:10.72]The camera can be combined with Microsoft's HoloLens 2 headset device. [02:18.80]While Microsoft has been using holoportation technology [02:24.24]for several years, NASA said it was the first time [02:29.56]it had been used "in such an extreme and remote environment such as space." [02:36.92]Similar technology has been used to assist doctors [02:42.96]performing remote operations and in telemedicine. [02:48.24]Telemedicine is a way for people to talk to doctors [02:53.44]and receive health care without having to visit a medical office, [02:59.12]treatment center or similar place. [03:02.68]Schmid described the technology [03:06.60]as "a completely new manner of human communication [03:11.16]across vast distances." [03:14.36]He said the process represents "a brand-new way of human exploration, [03:22.00]where our human entity is able to travel off the planet." [03:28.20]During the experiment, Schmid was able to speak with Thomas Pesquet, [03:35.32]a European Space Agency astronaut aboard the ISS. [03:41.24]Aexa Aerospace chief Fernando De La Pena Llaca [03:46.88]and several members of the company's technology team [03:51.40]also took part in the holoportation event. [03:55.84]NASA said the technology demonstrates a new form [04:01.24]of communication it plans to use on future space missions. [04:07.20]It could permit people on Earth to be holoported to space, [04:13.04]as well as send astronauts on virtual visits to Earth. [04:18.48]Schmid said the system could be used to hold private medical, [04:24.52]psychiatric and family meetings and to virtually bring important people [04:30.88]to the space station to visit astronauts. [04:34.76]He added that the next step could be to combine [04:39.76]holoportation with augmented reality technology. [04:44.84]Augmented reality, or AR, is a technology [04:50.04]that can project computer-created imagery [04:53.68]onto headsets like the HoloLens 2. [04:57.60]The images appear in the headsets [05:00.92]along with other physical objects in the environment. [05:05.72]AR has been used to help guide workers [05:10.08]through complex industrial processes. [05:13.60]"Imagine you can bring the best instructor [05:17.64]or the actual designer of a particularly complex technology [05:22.96]right beside you wherever you might be working on it," Schmid said. [05:29.12]NASA said holoportation technology [05:33.96]could greatly improve future missions into deep space. [05:39.24]It said one of the most important uses [05:43.20]could be to provide better and more personal communication [05:48.00]between astronauts and people on Earth. [05:51.36]The communication could be necessary [05:55.12]for medical or mission support reasons. [05:59.08]And, it could improve connectivity among astronauts [06:03.56]in space and their families back home. [06:07.60]But NASA noted one possible challenge [06:11.48]that could happen in future, planned missions to Mars. [06:16.48]Technology systems will have to find a way [06:20.72]to effectively operate with communication delays [06:25.32]of up to 20 minutes each way during travel to and from Mars.
