Je tako. Zato imajo astronavti s seboj 20kilske zverine in nato lastnoročno razvijajo fotografski film v dark-room-u na ISS-u ter muziko poslušajo iz radiation-hardened gramofonskih plošč ....

Zadeve imajo vse, gps, g-senzorje, kamero in še lasten vir napajanja.

Ja, GPS je na Marsu ful pomembna reč. Sicer pa put you money where your mouth is. In spacaj skup raketo, ki bo S3 dvignila v orbito, pol nam pa prek LTE povezave streamaj full HD video poleta. Častim stream server anytime.

Implications for space travel

Missions beyond low earth orbit leave the protection of the geomagnetic field, and transit the Van Allen belts. Thus they may need to be shielded against exposure to cosmic rays, Van Allen radiation, or solar flares. The region between two to four earth radii lies between the two radiation belts and is sometimes referred to as the "safe zone".[18][19]

Solar cells, integrated circuits, and sensors can be damaged by radiation. Geomagnetic storms occasionally damage electronic components on spacecraft. Miniaturization and digitization of electronics and logic circuits have made satellites more vulnerable to radiation, as the total charge in these circuits is now small enough so as to be comparable with the charge of incoming ions. Electronics on satellites must be hardened against radiation to operate reliably. The Hubble Space Telescope, among other satellites, often has its sensors turned off when passing through regions of intense radiation.[20] A satellite shielded by 3 mm of aluminium in an elliptic orbit (200 by 20,000 miles) passing through the radiation belts will receive about 2,500 rem (25 Sv) per year. Almost all radiation will be received while passing the inner belt.[21]

The Apollo missions marked the first event where humans traveled through the Van Allen belts, which was one of several radiation hazards known by mission planners. The astronauts had low exposure in the Van Allen belts due to the short period of time spent flying through them in the heavily-shielded Command Module. In fact, the astronauts' overall exposure was dominated by solar particles once outside the earth's magnetic field. The total radiation received by the astronauts varied from mission to mission but was measured to be between 0.16 and 1.14 rads, much less than the standard of five (5) rem per year set by the U.S. Atomic Energy Commission for people who work with radioactivity.[22]
