Yebbut did they ever launch a Lada on it? :D

I would've been even more impressed if they'd launched a Zil!

Turns out the super secret Zuma payload did survive. Its orbit has been spotted. And it may also have ejected a second vehicle.

New low-power laser tracking beacons for satellites (a.k.a. future space junk).

Not according to the official story. The latest version is that the satellite was lost but it was Northrop Grumman's fault. Handy story that -- no spy satellite, but no blame attaching to SpaceX.

Another one I missed in the last fortnight -- the FCC has approved SpaceX's broadband constellation.

Quote:
As recently as 2013, Russia controlled about half of the global commercial launch industry with its fleet of rockets, including the Proton boosters. But technical problems with the Proton, as well as competition from SpaceX and other players, has substantially eroded the Russian share. This year, it may only have about 10 percent of the commercial satellite launch market, compared to as much as 50 percent for SpaceX.


Quote:
What seems most remarkable about Rogozin's comment is that, for the first time publicly, the world's most storied launch provider appears to be ceding the commercial launch market to other providers—most notably a rocket company that didn't exist until 2002, and flew its first orbital rocket less than a decade ago.


The Russians even with a falling Rouble can't compete with SpaceX, they really should have been nicer to Musk all those years ago

Also possible SpaceX launch for NASA tonight

Well, to make oil you need to have a long period of carbon capture and storage by massive biological activity like the Carboniferous period on earth which lasted 60 million years. see https://en.wikipedia.org/wiki/Carboniferous

aka load and loads and loads and loads of trees. Did I say loads? I mean like shit loads of trees.


I don't think you need trees for oil formation, its more algae and plankton that are important

Terra Incognita wrote:
Then you need to bury that carbon using tectonic activity so that all that carbon gets locked underground for a few 10's or 100's of millions of years and over time it turns into coal and oil.

Mars is solid and geologically dead. It has no tectonic activity so it couldn't have buried any trees on the surface underground. And there is no, zero, nada, zilch evidence that it has had anything other than a few bugs ever on its surface. So no trees. No coal, No Oil.


Mars is not geologically active today but its very clear that is was in the past, Olympus Mons is the largest Volcano in the Solar system, its so large Galileo might have been able to see it, we also know that Mars had oceans and an atmosphere, so all the building blocks for oil were once present, therefore IMO its possible that Mars could have oil deposits

And thats before we start to wonder about Titan

There is no oil on Mars. If you want to transport it has to be electric

The only carbon-based fuel made on Mars will be made using the Sabatier Reaction to make Methane and its derivatives for rocket fuel and as a feedstock for organic chemistry. https://en.wikipedia.org/wiki/Sabatier_reaction


Yes but the Methane can clearly also be burned in an engine as back up, it would be foolish to rely on just one system

Even if Earth gets hit by a large asteroid or somebody lets off all the nukes it'll still be more habitable than Mars.

It's not quite about being emperor of your own planet it is about ensuring the survival of our species and he's doing it by getting it to pay for its self by creating a new massive off world economy.

Russia famous for making fun of a young Elon Musk and his rocket plans and formerly provider of the worlds leading low cost reliable launchers is struggling for business.

Can earth based organisms successfully procreate and raise healthy off-spring on a planet with 38% of the gravity of earth? What effect will the lack of Sun exposure have on Martian Humans? There has been some science done on mammal babies in space and then brought back to Earth but none on long-term off-Earth living.
