Is Millionaire Space Tourist Planning Trip to Mars?

Is Millionaire Space Tourist Planning Trip to Mars? | Good news from the Stars | Scoop.it
Dennis Tito's nonprofit organization may want to launch astronauts toward the Red Planet in 2018.
Guillaume Decugis's insight:
Plan would not be to land but do just a round trip. Still doesn't it sound crazy (and awesom!) that private money could beat governments in the space race?

Ion Thruster Prototype Breaks Records in Tests, Could Send Humans to Mars

Ion Thruster Prototype Breaks Records in Tests, Could Send Humans to Mars | Good news from the Stars | Scoop.it
A thruster being developed for a future crewed mission to Mars broke several records during a recent testing campaign.
Guillaume Decugis's insight:

The International Space Station just pulled off the photobomb of a lifetime | Good news from the Stars | Scoop.it
The hotly anticipated total solar eclipse passed over the United States on Monday (Aug 21). Heading southeast, it passed over a narrow and long swath of the country.

NASA just discovered a new solar system with 7 rocky, earth-size planets

NASA just discovered a new solar system with 7 rocky, earth-size planets | Good news from the Stars | Scoop.it
The planets orbit a dwarf star named Trappist-1, about 40 light-years, or 235 trillion miles, from Earth. That is quite close in cosmic terms, and by happy accident, the orientation of the orbits of the seven planets allows them to be studied in great detail.
Guillaume Decugis's insight:
Fantastic discovery by NASA. These planets are not gas giants but rocky planets like our own and some of them are in the habitable zone where water can exist in liquid form.

Elon Musk apparently wants to rebuild the internet from space providing global 1Gbps coverage

Elon Musk apparently wants to rebuild the internet from space providing global 1Gbps coverage | Good news from the Stars | Scoop.it
Elon Musk's aerospace company just made a big move to envelop the planet in high-speed internet coverage.
Guillaume Decugis's insight:

With a fleet of 4,425 satellites. No less. Which means more than the total number of satellites currently in Space. 

 

Ambitious program but great goal that would provide 200x more speed than what connected internet users get on average and perhaps more importantly internet access to areas that are not covered and potentially to the 4.2 billion of people who are not online yet.

A platform (rather than a plan) to colonize Mars

Guillaume Decugis's insight:

Elon Musk's proposal is probably super ambitious to some but his speech this week has the merit of making things pretty simple and straightforward in terms of what's at stake and how we can address the opportunity. 

 

The scope of his own plan is limited to transportation so he doesn't describe what Mars colonies will look like nor what people will do there. But that's the very interesting take-away to me: rather than attempting to plan everything in a typical government (or soviet-style?) way, he's proposing a platform for other entrepreneurs to build on and leverage the opportunities.

 

He's not saying "I've planned everything and you should all do what I say". He's focusing on solving the biggest hurdle (affordable transportation) and leaves the rest open. He makes the point that in the 1850's, no one lived in California but that the smart decision made was precisely to build a railroad to California... which became the most populous states a few decades later and economic leadership in technology and entertainment.

 

So in the same spirit, he's proposing a plan to reduce transportation cost to Mars to $100k/person with enough bandwidth to ship 1M people there over 40-100 years. 

 

What happens next is up to us.

Searching for aliens who already know we are here

Searching for aliens who already know we are here | Good news from the Stars | Scoop.it

Are we alone in the universe? To answer this question, astronomers have been using a variety of methods in the past decades to search for habitable planets and for the signals from extraterrestrial observers.

The first part of this venture has been highly successful: More than 2,000 planets around distant stars — so called exoplanets — have been found so far. The second part, the search for extraterrestrial intelligence (SETI), has not yet been successful.


Via Dr. Stefan Gruenwald
Guillaume Decugis's insight:

Learning the lessons from exoplanet search to transform the SETI program could lead to a much more focused search. And therefore more successful. Looking at the limited area of the sky where aliens are the most likely to be listening to us already... as they might track us the way we track exoplanets.

Mars One colonization project? Not gonna happen according to MIT

Mars One colonization project? Not gonna happen according to MIT | Good news from the Stars | Scoop.it
Whatever your views on Mars One, at the very least they have put the topic of Mars colonization in the public eye. Their plan, although ambitious, has received coverage from media across the world. For that, they can be applauded.

Interesting debate between MIT scientists and the Mars One team. While I'm always cautious of naysayers, you have to admit that the project seems foolish from the arguments they're making.

A Few Things I Learned While Attempting To “Skate” In Zero Gravity

A Few Things I Learned While Attempting To “Skate” In Zero Gravity | Good news from the Stars | Scoop.it

Simulated Moon and Martian gravity is way more fun for skating than no gravity at all. But you only get to experience those three times for 30 seconds each on the “Vomit Comet.” The rest of the flight is 12 zer0-gravity parabolas — each 30 seconds in duration. I did my first boneless backflip on our last martian gravity experience, and I was just starting to get the hang of doing ollies in slow motion.
