Voyager 1 and 2 still alive!!!! 38,000 mph!

Talking about patience, the first attempt at a heli flight on another planet is now scheduled for Sunday, April, 11. The next day the public will get a glimpse at success or failure of that attempt:

"A livestream confirming Ingenuity’s first flight is targeted to begin around 3:30 a.m. EDT Monday, April 12, on NASA Television, the NASA app, and the agency’s website, and will livestream on multiple agency social media platforms, including the JPL YouTube and Facebook channels."

There at least two problems with knowing anything about the boundary of the universe:

1. What we actually have is a boundary of the observable universe. It is defined by the observer's position in the universe and the speed of light. Objects farther away than the time needed for them to get their signal to the observer cannot be detected.

2. Because the expansion of the universe moves things away from the observer, he may loose sight of certain objects while others may never come within his sight, the speed of light not being able to compensate for the rate of expansion.

Those are the problems I somehow understand. There are more problems like, is the universe a container located within another container? That raises the question of the properties of that other container and we start all over again.

Cosmologists come at you with their sphere metaphor. The Earth has no boundary as long as you stay on its surface. As long as you can't escape from its surface, the Earth is infinite and repetitive.

The first experimental flight has been postponed to no earlier than April 14. Either a sensor returned an unexpected reading during the spin test or (more seriously) an electrical fault occurred.

the sphere metaphor is pretty good. why does "pi" -- an infinite number 3.14.... forever -- come up in circle calculus?

nothing to argue with here as to scientific theory on what PeugFra notes. we have no idea, because we cannot and never will know (unless the universe collapses at impossible multiples of "c" i would theorize that its so big it would take multiple millions of years until we could "see" the evidence) what's beyond what is "observable".

the headache-inducing thought is that most believe there is "nothing" outside the universe -- i.e., so therefore into "what" is it expanding? because "nothing" must in fact be "something" -- that thing into which the universe is expanding. hope that made sense.

EOD --- depending on whether one is a scientist or theologian, one needs "faith" to try to close any gaps in our understanding. All comes back to that..

deep thought brother ... there's a metaphor there that one can find in hard-core science.

 

[PeugFra]

So it needs an update of the software containing the command sequence to get rid of the error. That's gonna take some time, which means no flight attempt tomorrow and no new date set.

Ingenuity is now scheduled to take to the skies in the early hours of Monday, April 19th. Broadcasts are planned for 3:15 AM (PDT) and 11 AM (PDT). 3:15 AM (PDT) is close to lunchtime overhere, so I'll be watching!

Ingenuity is doing wonderfully! After four test flights it will now get something useful to do: scouting for Perseverance. It will fly ahead of the rover, land, and wait for its big companion to arrive.

A summary video on the last flight, April 30 (mostly stills, though):



And an article on technical lessons learnt during those test flights.

Video of two spacecraft studying the Sun. Apparently it takes 50 times more energy to get into orbit around the Sun than to go orbit Mars. Why in the video.

I love the diversity of knowledge and interest on this forum.
