Assembling the SpaceProbe for the first time might be a little daunting for some people.
Regardless of the reason, the SpaceProbe moves smoothly and stays where you point it.
But if getting the most scope for the least money is the primary goal, the Orion SpaceProbe
3 Altazimuth reflector has much to recommend it.
3 is neither as smooth nor as steady as the StarBlast or the XT4.
On July 4, 1997, the Mars Pathfinder spaceprobe
touched down on the red planet.

Now, we will verify that the accelerations experienced by the Pioneer-10, Pioneer-11, Galileo and Ulysses spaceprobes
do match significantly with the "cosmic-constant-of-acceleration".
Allan Rogers predicts that NASA spaceprobes
will weigh 10 kilograms (kg) or less down from the current weight of hundreds of kilograms, soon to be down to 100 kg.
And now, we will see that the accelerations experienced by the Pioneer-10, Pioneer-11, Galileo and Ulysses spaceprobes
do match strikingly with the expression (3):
