Will humans ever go to Mars?

  Will humans ever go to Mars? 


Nuclear rockets are always a risk to their environment. 


The problem with that kind of journey is that Mars is not the Moon. The distance to that planet is extraordinary for our rocket technology. For that journey, we require nuclear rockets, and there is a lot of political resistance against nuclear engines. It's possible to make lightweight nuclear reactors that use plutonium at the weapon enrichment level. But making that kind of reactor safe, requires a Moonbase. 

The plutonium pellets will transported to the Moon in the form of uranium. Then the nuclear reactor transfers that uranium into plutonium. Then the interplanetary craft's reactor will be loaded with plutonium. For making that process safe the operators must send uranium to the Moon in very small transport batches. The nuclear rocket will launch from the Moon orbiter because in the case of an accident. Radioactive debris drops on the Moon. 

This kind of project is huge. There is lots of money that is needed. And there are billions of other targets for resources that manned Mars missions require. But many other things can cause end-of-manned Mars programs. And one of them is that Mars can be polluted if there are humans on that planet.

If humans go to Mars too soon with non-completed technology. There is a possibility that the organic material that comes from Earth will pollute the entire Mars. 

There is the possibility that once in history there were tiny lifeforms on Red Planet. There could be DNA or RNA remnants of those bacteria that could be procaryotes. But the main reason why Mars station is not possible is that Mars is not safe. There is carbon dioxide ice under the shell, and that can cause dangerous collapses. Things like dust storms cause problems for antennas and power supply. 

For making some space missions safe. There is a need lot of information about the targeted planets. Before humans can enter Mars. There could be space stations that orbit the Red Planet even decades before humans can land on Mars. There is a need for a large space station that could be Von Braun's wheel. That space station or group of space stations can be used to remote control robots on the Mars surface. 

The mission of those robots is to search for lifeforms or lifeform remnants. Another mission of those space stations is to offer a safe place for astronauts in the case of accidents. The space stations offer sterile and isolated platforms for planetary operations. 

Before astronauts can land on other planets they must know if there are some kind of active lifeforms. Maybe that thing is not a problem on Mars. But on icy moons like Europa could be primitive lifeforms. Another risk on those icy moons is that the ice shell collapses.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to  form  the blue giant or too  small  it can collapse  straight  into a black hole . If  the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts.    The theory of hydrogen-burning supernovas consists  model  of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al. Ack.: CASU, CALET" (ScitechDaily, Astronomers Baffled by Ancient Galaxy That Mirrors Modern Milky Way) Researchers found the youngest Milky Way-type galaxy. The distance to the galaxy is enormous. And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

   "New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at  USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) The transcendenc...
