So what do I mean be real maps? USGS terrain maps are real maps.
There are cell phone applicationns for them.
The bigger issue is knowing how to use them. How to orient them, how to read them, what the symbology means.
This is clearly a dieing art. I learned long ago. Military and other outing organizations still teach it.
I prefer ANSI E-size USGS maps of the area I'm hiking. A compass, and a USGS terrain map are all I need... besides a good pair of eyes.
You do know that most of the TLI stages for the moon have crashed into it, starting in the 1960's.
They are a hazard to navigation otherwise.
Also, at impact, they are vaporized due to their kinetic energy so there is no trash other than atomic and molecular level pieces.
And this, right here, sports fans, is why one never, ever, keeps information online as ones sole repository. Buy a bloody archive drive or two. Better yet, but together a data server from old hardware you have at home! As to games, the demise of physical media is lamented.
Excrement. Look, I've been hearing this since I was a KID! That was 50 years ago. CEOs whine that they can't find people, and turn right around and cut pay and benifits, then bring in foreign workers or illegal aliens to do the job, yet we have people who have STOPPED LOOKING FOR WORK because they can't get a job though they've applied to HUNDREDS of them! They can't even get an interview! Shove it pencle pusher... shove it!
Quite honestly, this is a better arangeme t as government entities love to push their sode of the stopry depending on who's in charge. Granted, any organization can do this, just look at the way the MSM twists perception. Still, while no system is perfect, at least this one can be scrutinized without having to worry about retaliation by a government system.
Given all the knee jerk reactions, and the article not stating it, could it be that that the NSF has other priorities that could use the $45 million/year? Also, there are other countries with sensors in place around the world. I believe the Canadians have systems in both the Pacific and Atlantic as well. Perhaps it's seen as double coverage.
A couple of reasons that I can think of is maintinence cost, pollution and lifespan. By picking the sensors up for possible re-emplacement later, the life of the system is saves. Leaving the system to decay on the bottom would probably cause unnecessary polution.
