On July 20, 1969, astronauts Neil Armstrong and Buzz Aldrin walked on the Earth’s moon at a major time in human historical past. Four days later, they were trapped in American flight service during the Pacific Ocean-along with Apollo 11 command module pilot Michael Collins.
The astronauts were isolated with pride. According to the NASA security protocol, written six months ago, the three-month guest was escorted immediately by usHornet’s modified trailer from the Central Pacific splashdown website. target? Perhaps to prevent dangerous moon microorganisms from hitchhiking to earth with them. [Weird and cool things we recently learned about the moon]
In fact, as NASA quickly confirmed, there were no aliens lurking under the astronauts’ armpits or in the 50 kilograms (22 kilograms) of lunar rock and soil they collected. But despite this lack of literal extraterrestrial life, Apollo 11 astronauts nevertheless take aliens back to Earth in another way that may be felt 50 years later May have succeeded.
“At this time, about 30 civilians believe that the earth is being visited by saucer aliens, despite the evidence that it is very poor,” said Seth Institute senior astronomer Seth Shostak. —Searching for alien life in space— Advising Reside Science.
Shostak is trying to find a smart indicator of life in the universe in much of his life (and, appropriately, sharing birthdays with Apollo 11 touchdowns). Resident Science talked to him to further explore how the lunar touchdown changed the alien pursuit of science and the concept of the world. The dialog highlights (edited evenly for readability) appear below.
LS: What has the moon touchdown trained people about extraterrestrial life?
Seth Shostak: Not excessive. By 1969, most scientists expected the moon to be useless.
They knew that the moon had no atmosphere for 100 years as a result of the stars simply disappearing when they went behind the moon. If the moon has an environment, the stars will darken as you approach the edge of the moon. In addition, just look at the moon. There is no liquid, the temperature in the sun is many levels, the shade temperature is many levels minus-it is terrible!
As mentioned, I think that the lunar touchdown has influenced the general public concept of extraterrestrials. Until then, rockets were just science fiction. However, Apollo’s mission has confirmed that they may travel the world on rockets-perhaps aliens as well. I believe from a public perspective, this means going to celebrities is not always fiction. Suddenly, the universe has opened a little more.
LS: In 1969, did scientists think there were aliens elsewhere in the photovoltaic system?
Shostak: Mars was a lovely pink hope of extraterrestrial life in a photovoltaic system. In 1976, people were very optimistic that the Viking lander could have life on Mars. Even Carl Sagan thought there were creatures with legs and heads working there. Scientists were rather upset when they didn’t think there was much life on Mars.
For those who ask scientists where we talk about the best place to look for life in a photovoltaic system, they will probably say Enceladus or one of many different moons on Jupiter or Saturn. Nevertheless, the life of microbes may be very common on Mars, but exploring it requires digging very deep gaps and lifting objects. However, some of these satellites do not even require a spacecraft to land, as they have a geyser that launches the fabric at the appropriate location.
LS: Did the search for extraterrestrial intelligence (SETI) look like a 1969 round?
Shostak: In 1960, a trendy SETI experiment began with astronomers Frank Drake and Mission Ozma, who was searching for planets around two stars using radio telescopes. [No recognizable signal was found after four years of searching. ]
However, by 1969, SETI was done informally by individuals working in telescopes, hoping to try out coordinates near stars and determine the radio signal in their free time. However, it was not really organized until the 1970s when the NASA SETI program was launched. This was an important program, with $ 10 million in funding at one level per year, allowing NASA to build specific receivers, acquire telescope time and all other forms of space.
The NASA SETI program began observations in 1992, and Congress killed it in 1993! Eventually, a democratic lawmaker in Nevada killed it. Ironic members of Space 51 and extraterrestrial highways in Nevada have found that they have voted for the NASA SETI program.
