A) There is not that much Martian atmosphere to slow the "meteorite" to the point a "soft landing" and I can see no re-entry rockets on said rock; so your reasoning is bollocks.

In the BBC series Wonders of the Solar System, this type of non-crater-producing Martian meteorite is used as possible evidence that Mars had a thicker atmosphere in the distant past when these meteorites impacted. It was in the Thin Blue Line episode if I remember correctly.

High-tech masks and data gloves not withstanding, I've wondered why there's no plan to shoot unmanned ships to the nearest ten or twenty star systems even if it's 100 - 200 years before they get there and we start getting data back and even if in the meantime technology advances enough to make these initial ships pointless - e.g. warp drive is developed. There's a reasonably good chance that FTL travel won't be developed in the next 1,000 years (if ever) so why not try to accomplish something in the nearer term?

Is it possible to aim well enough to place a ship in orbit of a star 8 - 30 light years or so away? How much could we learn about a star system with a satellite orbiting a star at a distance roughly the same as between Jupiter and Saturn for example? Would it be any better than current or near-future Earth based imaging can provide? If such a satellite came into orbit of our solar system sent by another civilization, would we readily be able to detect it?

NaCl is still in heavy development, but the developers want to encourage low-level security experts to take a look at their design and code.

...and to come up with a saline solution.

Plus, a dragonfly design has already been done by the ISIT probe.
