Technology: One more step for humankind...
Let's be clear, this is not the first time humankind has made a childhood dream come closer to reality. As a child, I grew up reading the Adventures of Tintin.
Tintin, a journalist, was always accompanied by his dog Milou. Woof! Woof!
Problem solving is Tintin's business. In the book series, the Tintin character visited the moon and mars all dressed up in a spacesuit, even his dog strolled in with a custom outfit.
Tintin walked on the surface of the moon before the astronauts took the historic first step on the Apollo 13. When the lunar module landed in the late sixties, it was man's imagination on paper that came to life.
That created an uproar!
While the scientific community was pleased and hopeful, preachers widely condemned the enterprise and thought these planets were celestial entities that man had no business interfering with.
Tintin went on to the hidden side of the moon, stepped on both planets a first time before returning to Mars. As a young adult, reading Tintin's cartoons was both, a pleasure and an adventure in itself.
The moment of fascination enjoyed during this author's childhood came when Tintin and his crew welcomed Armstrong, the American astronaut, on the surface of the Moon. The latter stood at the bottom of the Apollo 13 ladder bewildered that he was not the first man to set foot on the Moon.
What prompted the second mission? Did the first mission fail? Would Perseverance be able to rescue, repair or destroy Curiosity?
Well done, NASA! (But, remember to give credit to Tintin :-) After the second Mars landing

Technology: Software key demonstration...
Ever wonder how things used to be years before Microsoft Windows. Imagine for a moment you were a software vendor back in the days of MS-DOS. What do you do to protect company information so that your competitors could not copy your intellectual property?
In response to these questions, what is called today a software key was invented. This is the only photo of such software available anywhere....
The picture was taken on October 4, 1990, as the timestamp indicates, an RS-232C male dongle was plugged into a female RS-232C located on the back of the Desktop computer. Thus, activating and protecting the software from being pirated.
