Convention Countdown

The Republican National Convention is in 4 days in Cleveland.

The Democratic National Convention is in 11 days in Philadelphia.

NASA has released the first picture of Jupiter taken since the Juno spacecraft went into orbit around the planet on July 4.

The picture was taken on July 10. Juno was 2.7 million miles from Jupiter at the time. The color image shows some of the atmospheric features of the planet, including the giant red spot. You can also see three of Jupiter's moons in the picture: Io, Europa and Ganymede.

The Senate is set to approve a bill intended to change the way police and health care workers treat people struggling with opioid addictions.

My husband and I once took great pleasure in preparing meals from scratch. We made pizza dough and sauce. We baked bread. We churned ice cream.

Then we became parents.

Now there are some weeks when pre-chopped veggies and a rotisserie chicken are the only things between us and five nights of Chipotle.

Parents are busy. For some of us, figuring out how to get dinner on the table is a daily struggle. So I reached out to food experts, parents and nutritionists for help. Here is some of their (and my) best advice for making weeknight meals happen.

"O Canada," the national anthem of our neighbors up north, comes in two official versions — English and French. They share a melody, but differ in meaning.

Let the record show: neither version of those lyrics contains the phrase "all lives matter."

But at the 2016 All-Star Game, the song got an unexpected edit.

At Petco Park in San Diego, one member of the Canadian singing group The Tenors — by himself, according to the other members of the group — revised the anthem.

School's out, and a lot of parents are getting through the long summer days with extra helpings of digital devices.

How should we feel about that?

Police in Baton Rouge say they have arrested three people who stole guns with the goal of killing police officers. They are still looking for a fourth suspect in the alleged plot, NPR's Greg Allen reports.

"Police say the thefts were at a Baton Rouge pawn shop early Saturday morning," Greg says. "One person was arrested at the scene. Since then, two others have been arrested and six of the eight stolen handguns have been recovered. Police are still looking for one other man."

A 13-year-old boy is among those arrested, Greg says.

After an international tribunal invalidated Beijing's claims to the South China Sea, Chinese authorities have declared in no uncertain terms that they will be ignoring the ruling.

The Philippines brought the case to the Permanent Court of Arbitration in The Hague, objecting to China's claims to maritime rights in the disputed waters. The tribunal agreed that China had no legal authority to claim the waters and was infringing on the sovereign rights of the Philippines.

Donald Trump is firing back at Supreme Court Justice Ruth Bader Ginsburg after she disparaged him in several media interviews. He tweeted late Tuesday that she "has embarrassed all" with her "very dumb political statements" about the candidate. Trump ended his tweet with "Her mind is shot - resign!":

Discussing The Mars Landing With My 137-Year-Old Grandfather

Aug 8, 2012
Originally published on August 8, 2012 12:23 pm

Yes, it was an amazing landing, an engineering triumph, a 150-million-mile slam dunk, spectacular in every way, except ... I think my grandpa would be disappointed. I'm not sure of this, since he died 50 years ago, but I have a hunch.

It starts with a handwritten letter he wrote back in 1907. He was a travelling salesman. He sold men's hats, and his job was to visit retailers all over the country. "One evening," he wrote, "train riding between Chicago and Kansas City or St. Louis, sitting the club car, I read a magazine, The Century..."

An article caught his eye. It was written by "Dr. Percival Lowell, Harvard, in charge of the Flagstaff Observatory". It was about Mars, and whatever Lowell said, my grandfather was wowed. It "opened my eyes", he writes.

Hmmm. I figured it shouldn't be hard to read what my grandpa was reading, so I put "Percival Lowell", "The Century" and "1907" into a browser up it popped: "Mars as the Abode of Life," yes, written by Lowell, and oh wow! What a story he told my grandfather!

Lowell had built an observatory in Arizona, had spent his nights surveying the red planet, had found evidence of some enormous construction project visible on Mars with lines of "surprising straightness," "amazing uniformity,"and "immense length" that persisted over the months.

Lowell was more storyteller than scientist. He ignored technical issues like the thinness of the Martian atmosphere, the different chemistry of its air, and concentrated instead on the drama building in his head.

Lowell decided that creatures on Mars — he didn't call them human, all he would say is that they could plan, organize and build on a global scale, were running shy of water, and getting increasingly thirsty. The planet, he said, showed evidence of drying, and these entities, to stay alive, had built a series of structures to move water from the melting poles to inhabited regions near the Martian equator.

He called them "canals" — this at a time when engineers on Earth had just built the Suez canal, and were still building the Panama canal. Canal building was hot, hot, hot technology in the early 20th century, and these Martians were designing on a scale that dwarfed human accomplishment, suggesting to him that not only is "Mars at this moment inhabited," but these canal builders were "of an order whose acquaintance was worth the making" — if we could get to them in time, before they perished.

From what he could tell, he told his readers, Martian life was at that very moment winking out, that these canal builders would soon die of thirst, there was no present way to span the distance between the two planets, so these remarkable neighbors he had just discovered would, "cosmically speaking, soon ... pass away." Civilization on Mars, Lowell thought, "...has not long to last," and all we could do is watch them contend with their fate across the void — and perish.

I don't know if my grandfather believed all of Lowell's narrative, but from the rest of his letter, I can tell he didn't overtly challenge the premise, that there were other intelligent creatures in the solar system, not mentioned in the Bible (that was, for my grandfather, a sore point) and that all this had "opened his eyes."

That was 1907. More than a hundred years have passed. Today, the stories we tell about Mars have gotten, or seem to have gotten, umm, smaller.

Lowell's canals turned out to be illusions. Two probes in 1976 found no convincing sign of Martian life, at least not on the planet surface. There remains the possibility that there is life under the ground on Mars, or failing that, that there was once life there, millions of years ago. The life we're imagining now is not a tool-making, canal building intelligence, but something more modest: a one celled carbon-based critter that lived in water and then died. Or maybe a methanogen, a bacteria that pooped (or still poops) gas.

A one ton machine has been plopped onto a low plain where water would have once been, and as my NPR colleague Joe Palca carefully and elegantly points out (when I grow up, I want to be Joe Palca), our goal is not to find Martian life, but rather to find building blocks of life, to see if life on Mars is or was possible.

We're not hunting for a Martian. We're not looking for a live body (or even a dead one). We are hunting for chemical traces that might have once supported the existence of a single-celled Martian — maybe.

Ah, the difference a century makes.

What's The Point?

But if my grandfather were to lean across the seat in his club car and say, "Why bother?" I'd say to him with the same breathlessness of Percival Lowell, we still want to know what you wanted to know: Are we alone? Are we the only ones? Is there life anywhere else? Even if we can't talk to it, pity it, admire it or fear it, still, any "it" would be a revelation.

"It" may have been our ancestor. Some "Its" from Mars might have bounced to Earth and become the seed of us. "It" may have started there, stayed there, died there, but at least we know it was there, which means life can happen in more than one place. "It" may have a different chemistry, a different logic than we do, in which case, we have evidence of truly alien life forms.

"It's" story may be less operatic than Lowell's version, but if there ever was an "It", no matter how simple, how small, I want to know. We all do. Even (if he doesn't know already wherever he may be) my Grandpa.
