CARL AZUZ, CNN 10 ANCHOR:  It`s pretty rare for the entire 100-member  U.S. Senate is called to the White House for a security meeting.  That`s  what`s 
first today on CNN 10.
While the subject of  yesterday`s event was North Korea, much of the information shared with  senators was classified, so we don`t know exactly 
what details were discussed in the meeting.  
There  was a statement released by U.S. government officials, though.  It said  the Trump administration sees North Korea`s pursuit of nuclear weapons 
and intercontinental missiles as an urgent security threat and that the  president wants to increase pressure on North Korea to stop these  programs.  
The White House says it wants to do this peacefully  with the help of allies like South Korea and Japan, but that the U.S.  is also prepared to defend 
those allies, as well as itself.
Some  of the senators who attended said they were glad to hear the White  House`s strategy for dealing with North Korea, others said they learned 
nothing new.  
The view from the other side of the Pacific appears to be an aggressive one.

WILL  RIPLEY, CNN INTERNATIONAL CORRESPONDENT (voice-over):  Army Day in  North Korea, the 85th anniversary of the Korean People`s Army.  More  than a 
million active duty soldiers, more than 6 million if  you count reserves and paramilitary, one of the largest standing armies  in the world.
We almost never see this side of North Korea`s men and women in uniform.
(on  camera):  This is a public holiday here in North Korea, which means  citizens are enjoying a rare day off.  And as you often see on days like  
this, lots of dancing in the streets.
(voice-over):   Carefully choreographed display of national pride, North Korea calls it  single-hearted unity.  Outsiders say these men and women 
have no other choice.
As  Pyongyang residents dance, a very different kind of demonstration on  North Korea`s east coast.  The nation`s supreme leader Kim Jong-un  showing 
force with what South Korea calls a large scale  artillery drill, less than two weeks after this massive military parade  and a failed missile launch.  
Analysts say these new North Korean missiles could some day carry nuclear warheads to the mainland U.S.
DONALD TRUMP, PRESIDENT OF THE UNITED STATES:  Our nation faces serious --  
RIPLEY:   A growing arsenal President Trump called a grave threat to the world.   He`s pushing the U.N. Security Council to punish North Korea for 
developing weapons of mass destruction that violate U.N. resolutions.
In  its own show of force, the U.S. deployed a nuclear submarine to South  Korea, as the U.S., South Korea and Japan conducted joint naval drills 
Monday, all this as the USS Carl Vinson moves closer to the waters off the Korean Peninsula.
The  approaching U.S. warships conjured memories for this North Korean  veteran.  Senior Lieutenant Colonel Un Yong Il speaks to me in front of  the 
USS Pueblo, a U.S. Navy spy ship North Korea captured in 1968.  
"The  Pueblo reminds me of another vote traveling very near the Korean  waters," he says.  "The Carl Vinson carrier.  We are no afraid.   Just  like 
we capture the Pueblo, we can sink that aircraft carrier."
It`s a threat made by North Korean state media, prompting the Pentagon to warn Pyongyang to stop provoking the U.S.
(on camera):  Are North Koreans worried that you may be headed towards war with the United States?
"It`s a grave situation," he says, "but we`re ready to counter the American threat with an all-out war and nuclear attack."
In  this militarized nation, even civilians are told they may someday have  to pick up arms, even on days of celebration, citizens say war with the 
U.S. is always looming on the horizon.

AZUZ:   The Trump administration has made a new proposal concerning taxes in  America.  The U.S. treasury secretary calls it the biggest tax cut and 
largest tax reform in U.S. history.  
But  analysts say there weren`t enough details in the proposal to know for  sure.  What is clear is that it would change U.S. tax brackets.   Generally, 
the more money Americans earned, the higher their  tax rate, the more they pay in taxes.  There are currently seven  different income tax brackets, 
ranging from 10 percent to 39.6  percent.  The Trump administration`s proposal would reduce the number  of brackets to three, ranging from 12 
percent to 33 percent and decreasing the taxes that most Americans pay.
But  as far as what businesses pay, from mom and pop shops to law firms,  today`s top tax rate is 39.6 percent.  The White House plan would 
drastically reduce that to 15 percent.  It could also reduce taxes owed by companies that do business overseas.
The  government gets most of its revenue from taxes.  Reducing them would  mean less revenue.  The plan doesn`t say how the difference would be  made 
up.  And Democrats criticize the proposal, calling it a  gift to corporations and wealthy Americans.  Analysts call the plan a  starting 
point that the Republican-controlled Congress could use as it develops its tax reform plan.

AZUZ (voice-over):  Ten-second trivia:
What are Saturn`s rings believed to be made of?
Rock and ice, gas and uranium, iron and cash, or copper?
According to NASA, the rings around Saturn are composed of rock and ice.
(END VIDEO CLIP)
AZUZ:   An unmanned spacecraft named Cassini is attempting to dive between  those rings and the planet itself, beginning what NASA calls its grand 
finale.
If  everything went according to plan, Cassini shot the gap at a speed of  more than 76,000 miles per hour yesterday and scientists were expecting  to 
hear from it by 3:00 a.m. Eastern Thursday morning.  
But  there was some uncertainty.  At that speed, any debris between Saturn  and its famous rings could have completely destroyed Cassini.   Scientists 
are hoping the information it sends back will help them learn about Saturn`s gravity and magnetic fields.

SUBTITLE:  Cassini`s memorable moments.
NASA launched Cassini in 1997 to explore Saturn and its moons.  
DR.  EARL MAIZE, CASSINI PROJECT MANAGER,JPL:  One of the most iconic  moments for Cassini was landing on Titan.  We actually have the European  
probe parachuting down through Titan`s atmosphere, while  Cassini flew over the top, picking up those signals and relaying them  back to Earth.
SUBTITLE:  In 2005, Cassini discovered plumes on Saturn`s moon Enceladus.
A global ocean was confirmed in 2015.
MAIZE:   Enceladus, the fact that it could actually have not only plumes coming  out, but a total subsurface ocean, it`s a global ocean, it`s warm.  
It`s all of a sudden looking like a place where life could originate.
SUBTITLE:  While orbiting Saturn in 2006, Cassini captured images of a hexagon-shaped storm.  
MAIZE:  And in Saturn, it is just cyclonic rims, a jet stream size.  In hexagon, it`s two Earths across. 
For the first time, it will go through the rings.  There`s about 1,250 mile gap in there that we`re aiming for.
SUBTITLE:  Cassini will disintegrate in Saturn`s atmosphere in September.
MAIZE:   It is a robot.  It is out of fulfillment.  It is at the end of its  serviceable life.  But you can`t help but feeling a certain sense of  loss 
and nostalgia for something you`ve been driving.  It`s like anything you`ve had a partnership with for 20 years.

AZUZ:   For kids and young people, U.S. government recommends at least an hour  of exercise every day.  For adults, it suggests between two and a half 
and five hours per week.  It doesn`t specify when you should exercise.   Experts say just making sure you do it is the important thing.
But  if you`re getting enough sleep, there are some benefits to working out  in the morning, having more energy throughout the day is one of them.
How do you get started doing that?
(BEGIN VIDEOTAPE)
DR.  SANJAY GUPTA, CNN CHIEF MEDICAL CORRESPONDENT:  I think one of the  important things to remember about becoming a morning exerciser is that  it 
can have added benefits both physically and mentally.  
It`s  also one of those things that is just easy to check off the list.   Because you know, it`s likely to fall off your list later on in the day.   
How do you convince yourself not to hit that snooze button?  Well, I`m there.  You`re there.  We`ve all been there.  
It  goes without saying that the first thing is make sure you are actually  getting enough sleep.  We are talking seven to eight hours.  And then  give 
yourself a little bit of accountability.  
Sometimes,  it`s a question of having a friend who is really going to hold you  accountable, make sure that you are getting up, make sure that you are 
doing that exercise routine and hold yourself accountable as well.   Make that deal with yourself.  Get that exercise out of the way and  reward 
yourself in small ways throughout the day because of it.  
Human  behavior is pretty simple when it comes to certain things.  If we do  things that we love we are much more likely to stick with doing them.   Why? 
It makes much more likely to do it for the long run.  
And that`s what can help you live through a 100.

AZUZ:   We`ll probably never need to know how to make a peanut butter and  jelly sandwich in space.  But just so we do, here`s Shane Kimbrough who 
recently came home from the International Space Station.  While he was  there, he explained that astronauts don`t have bread in space.  They use  
tortillas.  And every ingredient has to be taped down so it doesn`t float away and get blown around by the air conditioning.  
As  far as eating it goes, that`s the same as on Earth.  Seeing that will  probably make you aspiring astronauts jelly.  But I`m glad we can say  with 
that end, because men shall not live by bread alone,  opting for a tortilla is anything but a stale (ph) idea, and it gives  you a sense of the micro 
gravity of the situation when you got to keep all your orbits and pieces from floating off.
That`s about all I can digest.  I`m Carl Azuz.  CNN 10 returns tomorrow.
