Space Sunday

It is that time again…..time for me to bring my readers up to date on the happenings in space and our soon to be active, Space Force.

Most people could care less but I grew up with Buck Rogers, Rocky Jackson, Flash Gordon, etc……so I like space stuff and after all it is my blog so guess what?  Space News!

Lots of stuff to report…..us space nerds are on the job……

Lots of talk about settlers for the Moon……

It’s the year 3000. Having used up all of Earth’s natural resources, humans have become a spacefaring race and established colonies on the moon. Vast, sealed domes cluster across its surface, housing cities populated by hundreds of thousands of people. This cold, gray rock has somehow become humanity’s new home.

Of course, this is pure science fiction. But no vision of the future is complete without an extraterrestrial colony of humans, and since the moon is the closest celestial body to our planet, it’s the easiest to imagine as our futuristic home.

But does this vision align with reality? Will the moon one day be a hot property, and if so, how many people could its unwelcoming landscape realistically support?

Then those settlers will reach out to Mars……where will they call home?

The smaller of Mars’ two moons, Deimos, was named after the Greek god of terror — but the way former NASA flight surgeon Jim Logan sees it, Deimos could be a comfort zone for space settlers.

“The Mars-facing side of Deimos is probably the most valuable real estate in the solar system,” Logan, co-founder of the Space Enterprise Institute, said today at Seattle’s Museum of Flight.

Logan laid out his case for Deimos during a conference on space settlement, presented this week by the Space Studies Institute to highlight the late Princeton physicist Gerard O’Neill’s vision for humanity’s expansion into the solar system.

Will we ever find life on Mars?

Nasa is close to finding life on Mars but the world is not ready for the “revolutionary” implications of the discovery, the space agency’s chief scientist has said.

Dr Jim Green has warned that two rovers from Nasa and the European Space Agency (ESA) could find evidence of life within months of arriving on Mars in March 2021.

The ExoMars Rover, which has been dubbed “Rosalind” in memory of British chemist Rosalind Franklin, will search for extra-terrestrial life by drilling 6.5 feet down into Mars’ core to take samples.

Stay on the topic of Mars……what if “life” is found by the rovers now crawling their way across the planet?

Chief scientist at NASA Jim Green believes we’re just years away from finding life on Mars — thanks to the agency’s Mars rover and the European Space Agency’s ExoMars Rover, both scheduled to launch in 2020.

If the missions find life, Green is terrified of the implications.

“It will start a whole new line of thinking,” he told The Telegraph. “I don’t think we’re prepared for the results. I’ve been worried about that because I think we’re close to finding it and making some announcements.”

What about the other neighbor that we do not talk about much….Venus?

It seems that Venus once had a stable environment for awhile…

Venus likely maintained stable temperatures and hosted liquid water for billions of years before an event triggered drastic changes in the planet, according to a new study.

Now, Venus is a mostly dead planet with a toxic atmosphere 90 times thicker than ours and surface temperatures that reach 864 degrees, hot enough to melt lead. It’s often called Earth’s twin because the planets are similar in size. But the modern comparisons stop there.
However, a recent study compared five climate simulations of Venus’ past and every scenario suggested that the planet could support liquid water and a temperate climate on its surface for at least three billion years. Like the other planets in our solar system, Venus formed 4.5 billion years ago.
 
Life and water on Saturn’s moon, Enceladus…….

Scientists just found the most basic ingredients for life bursting from an ocean on Saturn’s moon Enceladus.

A new analysis of NASA data reveals the presence of organic compounds in the plumes of liquid water that shoot into space from the ocean below Enceladus’s icy crust.

These compounds, which carry nitrogen and oxygen, play a key role in producing amino acids ⁠- complex molecules that serve as the building blocks of proteins. Without proteins, life as we know it on Earth couldn’t exist.

Scientists have long suspected that the ocean below Enceladus’s surface could harbour the ingredients for life. Researchers had detected other organic molecules coming from the icy moon before, but this is the first time anyone has detected them dissolved in the water.

That’s critical, since it means the compounds could undergo deep-sea chemical reactions that produce amino acids.
