Or perhaps more correctly it has flown.
And uploaded some pics, inc one of its own shadow down on the surface.
More to come.

So a flying machine has taken to the skies on another planet, a mere 117+ years after the Wright Bros.
Yes! Looking forward to some near future APODs about it. I wish I could live to see where we are at the end of the next 117 years. Still hoping for a medical or technological breakthrough in life extension, or consciousness extension in my remaining 30-40 years!

Asteroids

<<Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Starfish are also known as Asteroids due to being in the class Asteroidea. They are found from the intertidal zone down to abyssal depths, 6,000 m below the surface.

Echinoderms first appeared in the fossil record in the Cambrian. The first known asterozoans were the Somasteroidea, which exhibit characteristics of both groups. Starfish are infrequently found as fossils, possibly because their hard skeletal components separate as the animal decays. Despite this, there are a few places where accumulations of complete skeletal structures occur, fossilized in place in Lagerstätten – so-called "starfish beds".

By the late Paleozoic, the crinoids and blastoids were the predominant echinoderms, and some limestones from this period are made almost entirely from fragments from these groups. In the two major extinction events that occurred during the late Devonian and late Permian, the blastoids were wiped out and only a few species of crinoids survived. Many starfish species also became extinct in these events, but afterwards the surviving few species diversified rapidly within about sixty million years during the Early Jurassic and the beginning of the Middle Jurassic.>>

"The historic test flight is planned for no earlier than Sunday, April 11."

Hopefully it would be neat if they make the first flight on 12 April, because that is the 60th anniversary of Yuri Gagarin's first flight into outer space. Just saying because that would be easier for future school children to remember the dates of first flight off planet Earth, and 60 years later the first flight on another planet.

<<Sputnik 2 reentered the Earth's atmosphere on 14 April 1958, at approximately 0200 hrs, on a line that stretched from New York to the Amazon. It was said to be glowing and did not develop a tail until it was at latitudes south of 20° North. The satellite burned up in the atmosphere.

[Sputnik 2 had been carrying] the first living creature (larger than a microbe) to orbit the Earth: a female mongrel originally named Kudryavka (Little Curly), but later renamed Laika ("Barker"). Her true pedigree is unknown, although it is generally accepted that she was part husky or other Nordic breed, and possibly part terrier. The pressurized cabin on Sputnik 2 was padded and allowed enough room for Laika to lie down or stand. An air regeneration system provided oxygen; food and water were dispensed in a gelatinized form. Laika was chained in place and fitted with a harness, a bag to collect waste, and electrodes to monitor vital signs. Early telemetry indicated Laika was agitated but alive and well, although the cabin temperature had already reached 43 °C by the third orbit.>>

Delayed until at least the 14th.
The blades have been spun up though, but first to a low, 50 rpm.

Intery, mintery, cutery corn,
Apple seed and apple thorn,

What neufer said. I'd say that "Niel Armstrong piloted the Eagle to a safe landing" and fly clear of using the word "fly".

And also, "Time flies like an arrow; fruit flies like a banana." -- often wrongly attributed to Groucho Marx. See https://en.wikipedia.org/wiki/Time_flie ... e_a_banana

Not the terminology I'd use. "Flying" a spaceship sounds to me like bad 1950s science fiction. You might "pilot" a spacecraft. I'd say that Armstrong safely "landed" the spacecraft, not that he flew it.

  • Neil Armstrong didn't fly the Eagle to a safe landing as an eagle would do.

<<Venera 4 (Венера-4) was a 1967 Soviet probe comprised an entry probe, designed to enter the Venus atmosphere and parachute to the surface, and a carrier/flyby spacecraft, which carried the entry probe to Venus and served as a communications relay for the entry probe.
Venera 4 was the first successful probe to perform in-place analysis of the environment of another planet. Venera 4 provided the first chemical analysis of the Venusian atmosphere, showing it to be primarily carbon dioxide with a few percents of nitrogen and below one percent of oxygen and water vapors. While entering the atmosphere it became the first spacecraft to survive entry into another planet's atmosphere. The station detected a weak magnetic field and no radiation field. The outer atmospheric layer contained very little hydrogen and no atomic oxygen. The probe sent the first direct measurements proving that Venus was extremely hot, that its atmosphere was far denser than expected, and that it had lost most of its water long ago.>>

<<Flight or flying is the process by which an object moves through a space without contacting any planetary surface, either within an atmosphere (i.e. air flight or aviation) or through the vacuum of outer space (i.e. spaceflight). This can be achieved by generating aerodynamic lift associated with gliding or propulsive thrust, aerostatically using buoyancy, or by ballistic movement.>>

<<A planetary flyby is the act of sending a space probe past a planet or a dwarf planet close enough to record scientific data. The first flyby of another planet with a functioning spacecraft took place on December 14, 1962, when Mariner 2 zoomed by the planet Venus.>>

<<Leroy Gordon "Gordo" Cooper Jr. (March 6, 1927 – October 4, 2004) was launched into space on May 15, 1963, aboard the Faith 7 spacecraft, for what turned out to be the last of the Project Mercury missions. The clock and then the gyroscopes failed, but the radio, which was connected directly to the battery, remained working. Like all Mercury flights, MA-9 was designed for fully automatic control, a controversial engineering decision which reduced the role of an astronaut to that of a passenger, and prompted Chuck Yeager to describe Mercury astronauts as "Spam in a can". "This flight would put an end to all that nonsense," Cooper later wrote. "My electronics were shot and a pilot had the stick."

Turning to his understanding of star patterns, Cooper took manual control of the tiny capsule and successfully estimated the correct pitch for re-entry into the atmosphere. Cooper drew lines on the capsule window to help him check his orientation before firing the re-entry rockets. "So I used my wrist watch for time," he later recalled, "my eyeballs out the window for attitude. Then I fired my retrorockets at the right time and landed right by the carrier.">>

(As an aside, I wonder how many years it's been on Mars. Oh ... 687 (Earth) days / Martian year ... so 31.8 years.)
