1 00:00:12,912 --> 00:00:14,848 I'm here to talk to you about 2 00:00:14,848 --> 00:00:18,852 an exciting radio telescope that is going to be placed on the moon. 3 00:00:18,918 --> 00:00:20,854 It is called ROLSES 4 00:00:20,854 --> 00:00:22,655 It stands for Radio Wave 5 00:00:22,655 --> 00:00:25,892 Observations from the Lunar Surface of the Photoelectron Sheath. 6 00:00:25,959 --> 00:00:30,063 It's a mouthful, but actually it's a very simple instrument and it's 7 00:00:30,063 --> 00:00:33,600 going to detect all kinds of radio emission that is falling 8 00:00:33,600 --> 00:00:36,603 on the moon. 9 00:00:36,836 --> 00:00:39,005 Right now, it is close to solar maximum. 10 00:00:39,005 --> 00:00:40,240 So the sun is producing 11 00:00:40,240 --> 00:00:44,411 a lot of coronal mass ejections and radio emission associated with them. 12 00:00:44,477 --> 00:00:48,314 And we can detect these radio bursts from the Sun. Jupiter can produce 13 00:00:48,314 --> 00:00:51,451 radio emission in this wavelength that we are interested in. 14 00:00:51,618 --> 00:00:53,053 And we can observe Jupiter. 15 00:00:53,053 --> 00:00:57,223 Even the Milky Way galaxy produces a low level of radio emission. 16 00:00:57,323 --> 00:00:59,426 We can detect those radio emissions. 17 00:00:59,426 --> 00:01:03,029 We also produce a lot of radio emission by manmade transmitters from Earth. 18 00:01:03,163 --> 00:01:06,099 And this radio interference can reach the moon. 19 00:01:06,099 --> 00:01:09,969 Characterization of the radio environment of the moon is very important. 20 00:01:10,070 --> 00:01:11,738 That's not been completely done. 21 00:01:11,738 --> 00:01:14,874 And therefore, ROLSES will be able to contribute in 22 00:01:14,874 --> 00:01:17,944 identifying various sources of radio emission on the Sun. 23 00:01:18,144 --> 00:01:20,246 If you are setting up an observatory on the moon, 24 00:01:20,246 --> 00:01:23,650 we should know what kind of radio interference we get back. 25 00:01:23,716 --> 00:01:25,018 Commercial lunar payload 26 00:01:25,018 --> 00:01:28,188 services, NASA and American companies working together.
