Octopus Overlords

MOSCOW (AP) — A Russian spacecraft on its way to Mars with 12 tons of toxic fuel is stuck circling the wrong planet: ours. And it could come crashing back to Earth in a couple of weeks if engineers can't coax it back on track.

Space experts were hopeful Wednesday that the space probe's silent engines can be fired to send it off to Mars. If not, it will plummet to Earth. But most U.S. space debris experts think the fuel on board would explode harmlessly in the upper atmosphere and never reach the ground.

The launch mishap was the latest in a series of recent Russian failures that have raised concerns about the condition of the country's space industries.

The unmanned $170 million Phobos-Ground craft successfully got into orbit, propelled off the ground by a Zenit-2 booster rocket just after midnight Moscow time Wednesday (2016 GMT Tuesday) from the Baikonur cosmodrome in Kazakhstan. After separating from its booster, 11 minutes later, it was supposed to fire its engines twice and head to Mars.

Neither engine fired. So the spacecraft couldn't leave Earth's orbit, flying between 129 and 212 miles above Earth. And that orbit is already deteriorating, according to American satellite tracking.

Um, it already has them - just watch Transformers #1. QED.

Um, guys?

When I was in grade school, before the Mariner flybys, we still thought Mars had canals and seasonal blooms of vegetation. After Mariner 9 we thought it was as dry and dead as the moon. Our contemporary view didn't start to take shape until the Viking landings in 76.

But then, while the Vikings were under development we assumed that astronauts would follow them to Mars in the 1980s...and now we're talking about maybe the 2030s at the earliest. So it hasn't all been progress.

It really is one of the more noble pursuits of humanity. Nothing lifts up and galvanizes a populace more than watching things like a moon landing or viewing pictures of extraterrestrial vistas. I know it's a lot of money for oftentimes very little actual return, but I truly think the intangible returns are what makes it worthwhile.

PASADENA, Calif. - Excellent launch precision for NASA's Mars Science Laboratory mission has forestalled the need for an early trajectory correction maneuver, now not required for a month or more.

That first of six planned course adjustments during the 254-day journey from Earth to Mars had originally been scheduled for 15 days after the mission's Nov. 26 launch on a United Launch Alliance Atlas V rocket. Now, the correction maneuver will not be performed until later in December or possibly January.

"This was among the most accurate interplanetary injections ever," said Louis D'Amario of NASA's Jet Propulsion Laboratory, Pasadena, Calif. He is the mission design and navigation manager for the Mars Science Laboratory.

Engineers deliberately planned the spacecraft's initial trajectory to miss Mars by about 35,000 miles (56,400 kilometers). This precaution protects Mars from Earth's microbes, because the Centaur upper stage of the launch vehicle, which is not thoroughly cleaned the way the spacecraft is, leaves Earth on the same trajectory as the spacecraft. The planned trajectory ensures that the Centaur will not hit Mars.

Mars might get a shot at a life cycle in a few million years if we seed it with microbes that can survive or even thrive there.

because what if there is already some sort of life that we can not detect that then gets wiped out by our smallpox.....er microbes?

The camera at the end of the robotic arm on NASA's Mars rover Curiosity has its own calibration target, a smartphone-size plaque that looks like an eye chart supplemented with color chips and an attached penny.

...

Edgett bought the special penny that's aboard Curiosity with funds from his own pocket. It is a 1909 "VDB" cent, from the first year Lincoln pennies were minted, the centennial of Abraham Lincoln's birth, with the VDB initials of the coin's designer - Victor David Brenner -- on the reverse.

"The penny is on the MAHLI calibration target as a tip of the hat to geologists' informal practice of placing a coin or other object of known scale in their photographs.

NASA's next Mars rover, the "Curiosity" Mars Science Laboratory, looks right on target for landing.

The MSL will arrive early on the morning of Aug. 6 on Mars, says NASA's Dave Lavery. "Everything looks healthy," Lavery says, aboard the spacecraft, launched last year.

Improvement in targeting of the rover's landing site may shave off as much as four months of surface driving time for the nuclear-powered rover once it lands, says Pete Theisinger of NASA's Jet Propulsion Laboratory in Pasadena, Calif.

The mission, designed for one Martian year, will explore the mountain, Mount Sharp or "Aeolis Mons", at the center of Gale Crater on Mars, looking for evidence of past habitats suitable for microbial life on the Red Planet. The new, smaller landing site is only 4 miles wide by 12 miles across.

Someday, decades or centuries from now, long after the rover has been sand-blasted and buried into oblivion, somebody exploring Mars is going to recover that penny. Imagine how much it will bring at auction.
