Perfection?
We know from too many grievous example's that navigation waste can be considered as hazardous waste; but just what is 'precise navigation?' NASA has provided a good clue in the form of an example.
A trip from Earth to Mars
Distances Calculator tells us:
The time taken to travel the average distance of 140 million miles from Earth to Mars would be about 8.4 months (235.2 days) each way.
- If you could walk from Earth to Mars at a brisk rate of 4mph would take about 4000 years!
- If you had a car and were abiding by the highway speed limit of 70mph it would take 228 years. [Can you tell me how long it would take in a sailboat traveling at 7 knots?]
- If you had a 747 Jet Plane the time comes down a whole bunch at just around 32 years!
At 11:50:00 UTC on 30 July 2020, the Mars Rover mission “Mars 2020” launched from Earth aboard an Atlas V rocket. At 20:55 UTC on 18 February 2021, roughly six and half months later, touchdown on Mars was confirmed; the EDL navigation system came to within 16 feet of its landing target.
Watch the landing:
That’s pretty close to perfection!
Nice job NASA

Daze of Woke and Wake
Wake Boards need a wake! How best to create a wake, than with a “wake boat.” But, what is a wake boat?—the definition please: Not so fast…..It seems that the New Hampshire legislature is embroiled in controversy in defining the term “wake boat.”
Aside from the fact that every boat is responsible for its own wake, we mustn’t get too legal here, else too much responsibility might befall those who are actually responsible.
Behold the slow-motion train wreck...
