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!":

Key Test Tuesday For Hypersonic Flight

Aug 13, 2012

Imagine being able to fly from Los Angeles to New York City in less time than it takes to commute from most of Long Island into Manhattan.

Tuesday over the Pacific Ocean off Southern California, there's going to be a test of an experimental aircraft called the X-51A WaveRider. If all goes as planned, it will accelerate to about 3,600 mph — a speed, as the Los Angeles Times reports, that could get you from L.A. to N.Y.C. in about 46 minutes.

That's nearly three time faster than the Concorde used to fly. The Lockheed SR-71 Blackbird, "the fastest aircraft propelled by air-breathing engines," as the Smithsonian National Air and Space Museum writes, could hit 2,200 mph.

Don't book your tickets yet for the WaveRider, though. The X-51A WaveRider is an unmanned craft. Plus, Tuesday's test will be considered a success if it can sustain hypersonic speed for about 300 seconds.

Still, the Times writes:

"Aerospace engineers say that harnessing technology capable of sustaining hypersonic speeds is crucial to the next generation of missiles, military aircraft, spacecraft — and even passenger planes."

The X-51A WaveRider program, "is a collaborative effort of the U.S. Air Force Research Laboratory, the Defense Advanced Research Projects Agency (DARPA), Boeing and Pratt & Whitney Rocketdyne."

Pratt & Whitney has posted two videos about WaveRider.

One is a mission animation that shows how it will be taken high in the sky by a B-52. The WaveRider will detach from the B-52's wing, then fire a rocket engine. That engine will detach once the WaveRider reaches about 3,000 mph. Then the "Scramjet" engine will take over. As the second video shows, it has no moving parts. If it works as planned, the aircraft will be going so fast that it will ride its own wave — hence its name — as air sucked in at hypersonic speed combines with jet fuel to produce more thrust.

After about 300 seconds, the test craft is supposed to break up and fall into the ocean.

By the way, NASA has an online "Mach number" calculator that lets you calculate the speed of sound at different altitudes and speeds.
