  • This is a serious engine.

  • In terms of horse power, you're looking at about 12 million

  • and four of these things put together would generate about 2 million pounds of thrust.

  • It's not new. NASA's RS-25 rocket engine has been around since the 1970s.

  • It's powered dozens of space shuttle missions.

  • But NASA is testing it again,

  • in the hopes that it will power future manned rocket missions to places like Mars.

  • Hi. I’m Carl Azuz. Welcome to the show.

  • We are one day after another Super Tuesday of sorts

  • in the U.S. presidential nomination process.

  • Voters in five states went to the polls yesterday to pick the Democrat and the Republican

  • that they want to appear on a presidential ballot this November.

  • The latest results from yesterday’s contest are at CNN.com.

  • There can be only one candidate from each party on the presidential ballot.

  • Each time a candidate wins a state,

  • he or she wins a certain number of delegates from that state.

  • The first candidate to reach a specific number of delegates overall would win the party’s nomination.

  • That’s made official at the national conventions over the summer.

  • But what if no one wins enough delegates to clench a party’s nomination?

  • With several candidates in the race on the Republican side,

  • this is a possibility.

  • And it could trigger something unique in American politics, a brokered convention.

  • What is a brokered convention?

  • As the primary fight continues to heat up,

  • we keep hearing people talk about the possibility of a GOP brokered convention.

  • The idea of a brokered convention.

  • That’s what we talk about with the brokered convention.

  • And if you do have a brokered convention.

  • But what exactly is it?

  • A brokered convention happens when no candidate has a majority

  • of the delegates needed to secure the nomination.

  • The Republican candidate needs 1,237 to win the nomination.

  • What happens at a brokered convention?

  • First, during the Republican National Convention, a delegate vote is taken.

  • This is called the first ballot.

  • And if no candidate has the number of delegates needed,

  • the convention is considered brokered and things start to get a bit more complicated.

  • Once the convention is brokered,

  • the delegates are longer tied to their original candidate

  • and are free to vote for whomever they want and all bets are off.

  • This is when serious wheeling and dealing takes place.

  • Delegates can be persuaded to change their vote,

  • and the candidate who originally have the most delegates

  • may lose support and can suddenly be cast aside.

  • The voting keeps on going until a candidate wins the designated number of delegates,

  • and this can take some time like it did in 1880.

  • The 1880 reference is also similar in that you had 14 guys running in that primary,

  • 14, just like this one.

  • And the frontrunners, there were three frontrunners going into this,

  • they went through 35 ballots, 35.

  • And then two of the frontrunners ended up throwing their support behind a guy

  • who wasn’t even running, Garfield.

  • Garfield became the dark horse, or an unexpected winner,

  • and this is what some people have been talking about when it comes to Mitt Romney.

  • It’s likely Trump is going to be the nominee,

  • but then we might have a brokered convention if he’s not.

  • And that’s clearly the scenario that Romney prefers,

  • which would of course, blow everything wide open.

  • So, will it come down to a brokered convention?

  • It’s rare. The last GOP brokered convention was back in 1948.

  • But for now, the race for delegates is on.

  • Here we go now with three of the schools

  • that have made request to be part of the CNN STUDENT NEWS "Roll Call".

  • Instituto San Robert is first up.

  • Great to see everyone watching in Monterrey, Nuevo Leon, Mexico.

  • To the U.S. east coast, where were looking up to the Hawks.

  • Mount Holly Middle School is in Mount Holly, North Carolina.

  • And in the northern state of Wisconsin, weve got the Raiders online.

  • Medford Area Middle School is in Medford.

  • Another political headline today:

  • the Obama administration has reversed its decision to allow oil drilling on the Atlantic coast.

  • The background here:

  • the U.S. government estimates there are billions of barrels of crude oil

  • and trillions of cubic feet in natural gas on the Atlantic Ocean’s outer continental shelf.

  • Last year, the Obama administration said that for the first time,

  • it would allow companies to search for oil in offshore areas east of Virginia,

  • down to Georgia.

  • Drilling there was supported by oil companies,

  • as well as lawmakers and governors who said it would create new jobs in the region.

  • Environmental groups, as well as dozens of cities and towns

  • on the East Coast opposed the decision.

  • Yesterday, the administration changed course

  • and said it would not allow offshore drillings in these areas.

  • It cited the local opposition, the current oil market

  • and the potential conflicts with other ocean uses as reasons for its decision.

  • The U.S. interior secretary said this would protect the Atlantic for future generations.

  • But the American Petroleum Institute said the decision was out of line

  • with what U.S. voters want and that it shuts the door on new jobs

  • and would increase energy costs for Americans.

  • For the first time, the National Football League is publicly acknowledging

  • that there’s a connection between the sport and brain disease.

  • Yesterday, during a discussion with the U.S. House of Representatives,

  • an NFL official was asked if he thought there was a link

  • between football and degenerative brain disorders like chronic traumatic encephalopathy or CTE.

  • His answer: certainly yes.

  • Previously, the league had avoided saying there was a link,

  • partly because it said it was waiting on more brain studies to be done.

  • But now, after evidence that several former NFL players had CTE,

  • the league is clearly stating that a link is there.

  • There’s no cure for CTE

  • and another problem is the disease can’t official be diagnosed

  • until after a player has died and scientists can examine his brain.

  • NFL football is more popular than ever.

  • Ratings are high. Revenues are in the billions.

  • The NFL says it’s continuing to improve equipment and make changes to the game

  • to better protect its players.

  • It remains to be seen if acknowledging the risks of the sport

  • will affect athlete’s decision to play in the future.

  • Charlotte Brown is a college athlete.

  • Like a lot of competitors, she’s played injured.

  • She’s played with broken bones.

  • And she hasn’t let the fact that she’s legally blind prevent her from

  • taking on one of the most difficult sports in track and field.

  • She started by counting her steps and her follow-through is why’s she’s today’s character study.

  • When you watch Charlotte Brown, it’s hard to believe she can’t see.

  • She does live so seamlessly that often people don’t know she’s blind.

  • The Purdue University freshman developed cataracts in both eyes

  • at 16 weeks old and had surgery to remove them.

  • I can see colors and I can see shapes and people.

  • But I will always read large print and I can never see really well.

  • In sixth grade, Charlotte’s vision got worse, and she was declared legally blind.

  • We just kind of hiccupped over it.

  • My parents, they never said, can you do that?

  • It’s just how are you going to do that?

  • A question they asked when she wanted to pole vault on seventh grade.

  • No one on my team was doing it and it seemed dangerous.

  • And I was like, ah, I wanted to do something dangerous.

  • Charlotte and her coaches came up with a strategy.

  • She places a beeper above the box where plants her pole and then counts the steps on her approach.

  • I have very sensitive hearing.

  • So, essentially, when I vault, I really don’t hear anything except for the beeper.

  • In her senior year, Charlotte won bronze at the Texas state high school championships.

  • I had a lot of kids come up to me and just think youre the world.

  • That’s really cool, just to know what youre doing is going to have an impact on them.

  • Now in college, the 18-year-old says the sky is the limit.

  • I’m scared of a lot of things, I just chose to do it anyway.

  • You just have to stare fear in the face and you just have to smile even if you can’t see it.

  • Dr. Sanjay Gupta, CNN, reporting.

  • If youve ever wanted to come to the CNN Center and hang out with me in person,

  • asking whatever you want -- check it.

  • Now you can. The CNN STUDENT NEWS Tour with Carl Azuz is live and filling up quickly.

  • It’s an in-depth journalism-focused tour specifically built around our show.

  • Walk-ups are not accepted. You do need to a reservation.

  • So, to get more info, click the banner on the right side of our home page at CNNStudentNews.com,

  • or email atltour@cnn.com.

  • Hope to see you soon at the CNN studios in Atlanta.

  • Finally today, ants -- the insects, not your mom’s sister.

  • Theyre strong, capable of lifting more than 100 times their own weight

  • and banding together to drag relatively massive objects, like this unfortunate millipede.

  • Well, researchers at Stanford University are trying to use micro-robots

  • to mimic the super strong team work of ants.

  • Working alone, they can move objects more than 2,000 times their own weight.

  • Working together, they can move a car.

  • This is three-and-a-half ounces of robots slowly moving 3,900 pounds of vehicle.

  • A truly gargantuan feat though it moves at an almost stagnant pace.

  • Of course, you could drive faster results by using a crank,

  • but at 20 bucks a pop, the robots are ant that expensive.

  • So, it’s really hard to say winch is better.

  • We hope youll pull together to join us again tomorrow.

This is a serious engine.
