Both skyhook and space elevator are very interesting concepts. But aside from technical issues that have to be worked out, there is the bigger political issue of disrupting the established space industry which is heavily based on rocketry, which, coincidentally, is also the technology used in modern warfare.

#MarsHelicopter Ingenuity, a novel and now proven concept, had also the potential to be disruptive, but is now shelved, too.

A proof of the "everything is politics" mantra?

Also worth mentioning is the fact that #Ingenuity's base station assembled out of COTS parts has suffered only the loss of 25 bits of memory out of 1 GB of RAM, which were isolated so that the new MGL algorithm could run.

The little #MarsHelicopter concept, including its innovative design both in aerodynamics and in electronics, proved to be much more useful than initially anticipated. No fanfare, big budget or hype, just very capable and passionate people doing their best.

YES they are. Here's a map showing the path of that flight. The rover had crossed that area about 3 weeks earlier:

@personifieddevil @BrodieOnLinux yes and no.

• You know.how much old stuff is still being deployed?

The #SpaceShuttle program got aborted because they couldn't get new old stock of radiation hardened chips, and to this day you have stuff like #ISA cards and #i486 systems in many #CriticalInfrastructure because noone can or wants to reimplement systems.

• GE literally used #PDP11's to automatically control their nuclear reactor designs because as old as they are the design has been known to work and re-certifying something new is basically almost impossible and not financially feasible.

And believe it or not, #git may be part of the toolchain for something that runs #VxWorks and goes into space:

• Stuff like the #MarsHelicopter being cobbled together from modern #Smartphone parts is more of an accident than actual planning, because it was a severly constrained effort.

As for #Rust, I rarely see benefits outweight the costs…
