Mars Perseverance Shows Off It's Tattoos

Very sexy.

Cool beans.

Question: Is Perseverance a living being since it's about to deliver a baby named Ingenuity?

Would that be a first birth recorded in Mars' history?

 

[Commander Dutch]

No, but I'm hoping Ingenuity flies as advertised.

Same here. I think it will. With 1/3 gravity and how light Ingenuity is, it will at least lift off with ease.

No doubt NASA has done their math about flight physics on Mars, but shit happens. The Mars Polar Mission failed due an engineering failure AKA math/coding failure.

Flaw in the code

"The lander was as robust as we could make it. But it was very lightweight...a rather delicate structure," Jolly told SPACE.com. "So most of us don't believe that, if it plummeted that far, it would be able to do anything...certainly not be able to call home."

Jolly envisions that the Mars Polar Lander's wire harnesses and boxes of electronics and equipment couldn't stand up to the g-forces from a harder-than-planned landing. The probe's legs would have likely crushed too.

"The whole thing would essentially implode on itself when it hit," Jolly said.

As for the cause of the crash, the investigation's findings are reasonable, Jolly said.

"That's because we know there's a known flaw in the [software] code that we found," Jolly advised. "That is why we have such a high confidence that the real cause was found...and we are moving on to correct that for future landers."

What if they find out that the real cause is an actual bug?

I remember something about moths being attracted to all of the vacuum tubes and causing shorts.

I remember something about moths being attracted to all of the vacuum tubes and causing shorts.

Grace Hopper was the first to discover it.

In 1946, when Hopper was released from active duty, she joined the Harvard Faculty at the Computation Laboratory where she continued her work on the Mark II and Mark III. Operators traced an error in the Mark II to a moth trapped in a relay, coining the term bug. This bug was carefully removed and taped to the log book. Stemming from the first bug, today we call errors or glitches in a program a bug.

This illustration is of two small drawings inscribed inside the front left wheel of the Mars Perseverance rover. One figure represents the tracks that the rover leaves as it drives on Mars. The other resembles that same pattern, twisted into the shape of DNA. The symbols represent humanity’s fundamental drive to invent the tools necessary for exploration, and serve as a reminder that our space robots are of human origin.

NASA’s Jet Propulsion Laboratory in Southern California built and manages operations of the Mars 2020 Perseverance rover for NASA.

Ingenuity touches down for first cold night on Mars alone

"The first helicopter on Mars is officially on Martian soil.

NASA's Mars helicopter Ingenuity touched down on the surface of the Red Planet after being dropped by its mother ship, the Perseverance rover, the space agency announced late Saturday (April 4). The helicopter's first flight is just over a week away.

"#MarsHelicopter touchdown confirmed! Its 293 million mile (471 million km) journey aboard @NASAPersevere ended with the final drop of 4 inches (10 cm) from the rover's belly to the surface of Mars today," officials with NASA's Jet Propulsion Laboratory in Pasadena, California wrote in a Twitter announcement. "Next milestone? Survive the night.""
