“Deep space” usually refers to somewhere beyond Earth’s orbit, at least.
Deep space is one of those terms that has a bunch of definitions, and usage has shifted over time. I see that today it’s mostly used your way, though not always, but I’m pretty sure that back in the 1960s, deep space was anywhere beyond low orbit.
NASA thought so. Its Deep Space Network appears to have begun work in 1966. (Pictures were all over the Guam Daily News.) In 1975, a report gave its specs.
According to a 1975 NASA report, the DSN was designed to communicate with “spacecraft traveling approximately 16,000 km (10,000 miles) from Earth to the farthest planets of the solar system.”[10] JPL diagrams[11] state that at an altitude of 30,000 km (19,000 mi), a spacecraft is always in the field of view of one of the tracking stations.
I read somewhere that Italy has more surnames per capita than any other country. I wish I had a cite, and I’m not sure I believe it, but I’m willing to believe there are more than the surrounding countries. Some Italian names are common throughout the country, but there are quite a few very rare ones. One of our family names was born by a local historian, who traced it to an ancestor alive around 1500. What started out as a nickname became a surname (though what it means I can’t seem to find out.) All people with that surname descend from that individual.
Do you mean “borne”? Because if a name was born by the historian, it’d be very simple to trace. 
I did mean borne. And I know the difference. Not sure whether it’s a foolish typo or autocorrect happening when my back was turned.
I was listening to the audiobook of Douglas Preston’s "The Lost City Of The Monkey God" the other day and was surprised to discover the narrator was Bill “Danger Will Robinson!!” Mumy.
Certainly having a recurring role on “Babylon 5” helped bring him out of obscurity.
Today I learned that the term ‘Bluetooth’ was actually named after a 10th Century King of Denmark, who unified Denmark and Norway.
Scholars say Harald was nicknamed “Blåtand,” meaning blue tooth, because he had a dead tooth that looked blue and dark.
In December 1996, Intel’s Jim Kardach, who had read a book on Viking history, suggested the name Bluetooth as a codename until the marketing group could come up with a formal technology name.
And the logo for bluetooth is superimposing the runes for B and T

I have a Scottish ancestor who was named Beatrix Elphinstone.
The history podcast I’m listening to has just introduced us to a character from the English Civil War named Praise-God Barebone.
If you look at the ratchets, sockets, extensions, etc. at a tool store that targets consumers, you’ll see three different “drive” styles: 1/4 inch square drive, 3/8 inch square drive, and 1/2 inch square drive. This design has been around for many decades. I was also aware of 3/4 inch square drive that some professional mechanics use when working on trucks.
I learned today that there is a 2-1/2 inch square drive. The sockets are very large and very expensive, ranging from $1000 to $7000 each. What in the heck are these things used for? Are they for the oil & gas industries?
Ever seen the bolts used to hold bridges and steel frame buildings together? Huge cranes and other construction equipment comes to mind also. It ain’t gonna be easy to remove or torque nuts and bolts that big.
Maybe needed for the next time they unbolt the Space Needle?
I hope they use grease on the threads when they torque those things down.
Nah. Just spray some WD40 on it.
Once again. I think again since I’ve told this to a lot of people. WD-40 is not a good lubricant. It dries and leaves a stick residue behind. The WD stands for Water Displacer. It helps to loosen bolts because it softens rust and other contaminants enough for removal but other penetrating oils do a better job of that. Spray it on nuts and bolts after they’ve been tightened to prevent water future water penetration. Just use light machine oil for lubrication during installation.
