Over the course of its nearly decade-long stay on Mars, NASA’s Curiosity rover team has considered making a couple of unusual modifications to the robot’s structure.
Driving around on Mars for that long has been pretty rough on Curiosity’s wheels. And as the damage worsens over the coming years, the NASA crew might decide to steer Curiosity into a sharp rock in order to rip out its own wheels, IEEE Spectrum reports. That way, there’s less of a chance that the damaged pieces end up breaking Curiosity’s wiring or other components, bringing the whole mission to a halt.
Break a Leg
Thankfully, IEEE Spectrum reports that even the most damaged of Curiosity’s wheels could survive for another decade or more before they need to be removed. That’s based on NASA’s predictions for how much driving the rover will do over the coming years, coupled with a recent effort to stick to gentler terrain as much as possible.
“Since other mitigations that the team has put in place are extending wheel life predicts further and further into the future, it is unlikely that we will need to perform a wheel shed maneuver,” Curiosity team member Evan Graser told IEEE Spectrum. “There’s always a chance of reaching the end of a wheel’s life during the mission, but we’re many years away from even needing to make the decision whether to pursue shedding further.”

The land rover Perseverance is also on Mars. Brlly Lewis (MASSIVE SCIENCE) reports:
Visions of humans on Mars are now one step closer to reality. The Perseverance rover, which has already recorded the first sounds from another planet and flown the first helicopter on Mars, recently made another historic first—extracting oxygen from the Martian atmosphere.
Last month, the rover fired up one of its experiments known as MOXIE, the Mars Oxygen In-Situ Resource Utilization Experiment. Like the Ingenuity helicopter, this experiment is a technology demonstration, where scientists try something entirely new and never before attempted as part of a larger space mission.
Inside the small metal box that is MOXIE, Martian air was heated to almost 1,500 degrees Fahrenheit, splitting carbon dioxide (CO2) into one carbon monoxide (CO) and one oxygen atom (O). Mars’s atmosphere is around 96 percent carbon dioxide, so there’s plenty to use there! In its first hour-long test, MOXIE produced 5 grams of oxygen, enough for an astronaut to breathe for 10 minutes. Scientists will run a few more tests with MOXIE during the rest of the rover’s mission, trying to see how much oxygen it can make and how fast.
MOXIE addresses two huge challenges in human space exploration on Mars — finding enough breathable air for astronauts to stay alive, and bringing enough fuel for the rockets to make a return trip to Earth.
I don't see a trip to Mars in my lifetime. I could be wrong. I do worry that when that does become available some people will really trash our planet thinking we now have other options. We really need to take care of the Earth.
"Iraq snapshot" (THE COMMON ILLS):
Thursday, May 13, 2021. Finally an Iraqi activist's assassination over the weekend gets attention from a US newspaper, protests continue in Iraq, and much more.
Over the weekend, Ihab Jawad al-Wazni was assassinated in Iraq, one of many assassinated since the October Revolution began in the fall of 2019. Yesterday, THE WASHINGTON POST became the first US paper to note this assassination. Louisa Loveluck and Mustafa Salim report:
Mass street demonstrations were crushed last year with deadly force, often by paramilitary groups that the protesters have denounced. Now as some activists prepare to run in elections, prominent figures in the protest movement are being picked off while they walk the streets or drive home at the end of the day.
The assassinations, officials and human rights monitors say, underscore the reach of Iraq’s militia network — to punish citizens who dare to criticize it and control a political system meant to hold it accountable.
Not a fan of the outlet OPEN DEMOCRACY but I've complained repeatedly about the lack of coverage of Ihab so we'll note that Nabil Salih covered this issue yesterday afternoon:
Nightfall is also the time that militiamen and terrorists come out to play, their bullets and rockets punctuating the grim silence.
The latest victims include Ihab al-Wazni, an activist shot dead outside his home in Karbala in the early hours of Sunday 9 May. Just 24 hours later, journalist Ahmed Hassan survived an assassination attempt in al-Diwaniyah.
The state never runs out of promises that it will punish and hold accountable the perpetrators, but ordinary Iraqis continue to die so easily. All in all, Iraq Body Count recorded 235 violent civilian deaths in the first four months of 2021 alone.
The assassinations, says a statement from the Iraqi High Commission for Human Rights, are proof that the security system is failing to protect activists.
[. . .]
In today’s Iraq, the bar for success is so low that the government carrying out even the simplest of its obligations is touted as an achievement.
The faces of fallen protesters graffitied on the streets of Baghdad are a reminder of a bloodbath whose architects are still unpunished.
In October 2019, Iraq’s youth took to the streets, to demand a dignified life akin to that enjoyed by many of their rulers’ families abroad. They were slaughtered like sheep by unidentified gunmen, under the former government of Adel Abdul Mahdi.
Hundreds were killed and thousands were wounded in an unequal standoff that is still being falsely described as “clashes” by international media.
That year, the usual chaos, corruption and death was a part of everyday life for most Iraqis.
One activist assassinated is appalling and news. A wave of assassinations -- an ongoing wave of assassination -- should be a huge topic. Rasha al-Aqeedi notes:
For perspective, everyone in this video collage was killed by Iraqi security forces or assassinated by militias. They were activists, journalists, protesters, community leaders.
And she's referring to this Tweet by Herak:
For all the pretense of being 'woke,' the US continues to stick its head in the sand when it comes to the suffering in other countries. The activists in Iraq are living in the destruction that the US government created. So it is appalling that the US press can't cover this, doesn't want to cover this. Maybe its their guilt over selling the Iraq War? Probably not because guilt really isn't an emotion journalists are known to have.
Ihab died, in part, because of journalistic silence. He wasn't the first killed or the tenth or the fiftieth or the hundredth or . . . There was a lot of time for the press to run with this story and amplify what has been going on. The culture of silence allows these murders to continue.
Geneva4Justice offers this Twitter thread:
The press too often silences the deaths and it also silences the reactions to the death. Suadad al-Salhy (MEE) notes that the response to Ihab's murder was to call for more protests. And the protests continue and the protesters continue to be attacked. This morning, Sura Ali (RUDAW) reports:
Security forces in central Iraq’s Babil early Thursday arrested large
numbers of protestors who were part of reinvigorated demonstrations in
the city following the assassination of a prominent activist, a local
activist confirmed to Rudaw English.
Masses of protestors, who have taken to the streets since the
assassination of Karbala activist Ihab al-Wazni on Sunday calling for
accountability, were arrested overnight, according to Babil activist
Ammar al-Ghazali.
Videos on social media show clashes between riot police and
demonstrators near al-Thawra Bridge in the center of the city.
Protesters set tires on fire on the streets, while security forces fired
Molotov cocktails to disperse the protesters.
"The protesters agreed to declare a truce for three days during Eid
al-Fitr, after which the escalation will resume in the case Wazni’s
killers are not revealed, and the arrest campaign against protesters and
activists continues," Ghazali told Rudaw English.
Let's note this.
1) GOW-an -- like OW with a G. This is always a pet peever of mine. I applauded Bruce Willis when he interrupted Johnny Carson on THE TONIGHT SHOW to say, "It's Demi." Demi Moore's first name does not rhyme with Emmy. People need to know basic facts. You decide to do a full segment on Rose McGowan know the person's name. It was repeatedly mispronounced.
2) Stop b.s.-ing. Know your s**t. I'm just not in the mood. When Rose is calling out Alyssa and CAA, she's not, as THE VANGUARD says, implying that her agent told her it was a good publicity move.[Clarifiaction added for those who did not stream the video, Alyssa's agent did not tell her that faux pretense abotu #MeToow was a good publicity move. Rose is referring to CAA's well known history of exploitation of women.]
I do not expect you to know the history of CAA. How long before anyone wanted to give two s**ts, Debra Winger was seriously calling it out and had to go back there because it was where the work was. It was a hideous place. And it used actresses. There's a French actress they pimped out to Harvey. We all know this story, in the industry, and many more stories. I don't expect THE VANGUARD to know it. I do expect them to grasp that Alysaa's CAA connection -- the only thing that has gotten her jobs in recent years -- is her husband who was a CAA agent until recently (unless he's still with CAA but I'm told he departed weeks ago, that may be incorrect). CAA would be no more if the #MeTooMovement was for real.
I know Rose, I support Rose. But get her name right and don't distort what she's saying because you didn't do the homework.
