It would continue to drive if it wasn’t autonomous, ”says the specialist. “If a rover is standing on a cliff and sending an image back, this time delay would cause it to receive the order to stop too late. Because: Until a signal from Mars reaches Earth or vice versa, it can between 4 and 22 minutes last. It is also essential that probes and rovers can operate at least partially autonomously.
#RADIO SILENCE VS NO CONTACT SOFTWARE#
“The software of a rover is basically developed in such a way that it can continue to work autonomously for a short period of time, ”says the expert. The rovers are completely inactive during this critical time but not.
#RADIO SILENCE VS NO CONTACT UPDATE#
During this period, however, there will be no clever, because the risk is too great that the update will only partially arrive and, in the worst case, the entire rover will become inoperable, ”says Tlustos. “The rovers usually also receive software updates, as we know from our cell phones. New commands are issued at this time according to NASA in any case not clever, especially since it is impossible to predict which information will be lost due to disturbances caused by charged solar particles. We then speak of the new moon.Īccording to Tlustos, the point in time at which data transmission is not even possible is when Mars is exactly behind the sun. “If you look from the earth to the moon during this period, it looks dark to us,” says the expert. In the case of a conjunction, on the other hand, the moon is between the sun and earth. I have the sun, the earth and then the moon, which is fully illuminated when viewed from the earth, “he says. When the moon is full, the arrangement of the sun and moon is in opposition to one another. “We also know this from the sun, earth and moon. These phenomena can be observed from the earth with all possible celestial bodies. At this point in time it is a good time to start missions to Mars, ”said Tlustos. “At this time, Mars is very close to Earth. In contrast to this, the sun, Mars and earth are in a line from the earth’s point of view every 2 years – one speaks of one Opposition. Opposition is a favorable period for Mars missions “They survive several conjunctions during which communication with the earth is not possible”. Meanwhile, the missions to Mars have been relatively long and the probes and rovers have lasted for several years. That’s a known problem, ”says Reinhard Tlustos, Board of the Austrian Space Forum (OeWF) opposite the futurezone.
“At this point in time, most space projects have problems with communication because the signals are not arriving directly. The phenomenon is called conjunction signifies and occurs every 26 months on. Because at this time there is radio silence between Earth and Mars because the sun is pushing between them and disrupting data transmission. The rovers, probes and helicopters only carry out their activities to a limited extent during this time. Zhurong will be put into safe mode from mid-September. The sun disrupts data transmission between Mars and Earthįrom the October 2nd to 14th the Mars rovers have, however Sendepause and are on their own. Since his instruments are still intact, he is now supposed to continue working and help with the exploration of former life in the south of the region, where a dry ocean is suspected. That would actually have ended his mission. He did geological investigations for 3 months, this project has already been completed.
In the region Utopia Planitia is the rover Zhurong the China National Space Administration (CNSA) On the way. He has already proven this several times. It just should prove whether motorized, controlled flights are possible in the extremely thin Martian atmosphere. He is accompanied by the helicopter Ingenuity. He collects rocks and is supposed to help researchers in their search for past life. It is equipped with 10 instruments – including cameras, spectographers and meteorological tools – which help it to study rocks, atmosphere and radiation.Īround 3.700 Kilometer the rover goes on Perseverance his duties since February 2021 Crater Lake after. Since 2012 the NASA-Rover Curiosity the Gale-Krater on mars.
