Morning Roundup: A bad case of 'roids edition

Good morning, Houston. If you spend your days worried that an asteroid will slam into Earth, killing us all, this probably won't do much to ease your mind: NASA says it can identify all the asteroids that could hit the Earth, but it's not sure it has the money to do so. The agency estimates it would cost $1 billion to find at least 90 percent of the 20,000 potentially hazardous asteroids and comets by 2020, a job Congress asked NASA to take on a couple of years ago. The good news: We've made it this far without a big crash. The bad news: Officials say that even if one of these asteroids explodes before it hits the Earth, it could devastate an area the size of Maryland. The good news: Maryland's really not all that big.

>> The right way to stop wrong-way drivers?: A system is being tested along the Westpark Tollway that would alert traffic monitors when someone enters the freeway going the wrong way — but is such a system really worth the cost? Some observers say no: The number of collisions caused by people going the wrong way on freeways is low, and even if authorities were warned when someone entered a roadway headed in the wrong direction, it would be hard to catch them before they caused serious problems. Other possible solutions, including road spikes and different signage, also might not work, experts say. Houstonist's solution? Drive a tank.

>> If you lived here, you'd be home: The former home of indicted ex-TSU President Priscilla Slade is up for sale again: Houston Texans draft pick Mario Williams bought the house in July for $1.7 million, and now he's trying to unload it for $2 million. So what makes the house at 203 Terrace Drive worth that much? Location, location — and backstory. Here's the listing.

>> Embracing the peso: Pizza Patrón, the Dallas-based pizza chain that got a lot of attention when it announced in January it would accept Mexican pesos at its U.S. locations, said Monday that the "Pizza por Pesos" program will continue through April. The chain, which claims 60 percent of its customers are Hispanic, says it's trying to make things easier for people who travel to and from Mexico frequently and might have some unchanged pesos left over — and we're sure it didn't hurt that sales have risen 35 percent amid the publicity over the peso program, too. Pizza, anyone?

>> Today's weather: Another day in paradise — enjoy it while you can, because it'll be summer soon enough. It's still kind of chilly outside now, but look for an afternoon high around 68 with clear skies. Tonight it'll remain clear, letting the temperature drop to 45. Long-term, looks like we'll see sunny and mild afternoons through at least Saturday.
