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 cleanse 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.
What exactly is it?
A brokered convention happens when no one 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 we`re looking up to the Hawks. Mount Holly Middle School
is in Mount Holly, North Carolina.
And in the northern state of Wisconsin, we`ve 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 thousands of cities and
dozens 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 similar 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 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 you`re the world. That`s really cool,
just to know what you`re 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.

Finally today, ants -- the insects, not your mom`s sister. They`re 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 you`ll pull together to join us again tomorrow.
