(CNN) - NASA is set to launch the world's largest rocket Tuesday, conducting research to help return astronauts to the moon.
The 327-foot rocket, called the Ares I-X, is set to launch at 8 a.m. ET from Kennedy Space Center in Florida, NASA said. The empty rocket will help NASA collect information for future missions.

"Ares I-X will bring NASA one step closer to its exploration goals to return to the moon for ambitious exploration," NASA said in statement.
The launch, which NASA is calling a test, is among four test launches of Ares I-X that will go on until 2012.

For Mary, a single mother of a two year old boy, the economic downturn plaguing the country has deeply affected her. When her son was born in 2007, a record 40% of children – approximately 1.5 million – were born to unmarried mothers. As a single parent, Mary juggles her education and job in order to maintain a comfortable lifestyle for her and her son.
“Women are expected to be mothers and caregivers while going to work or school. I’m competing against men that don’t have the same expectation. I have this extra burden because I’m expected to be able to do both.”
Mary takes on extra shifts and works holidays so that she can rent a condo in a gated community in the Pembroke Pines area of South Florida because she wants to raise her son in a safe residential suburb.
She commutes an hour both to work and school in lower income areas where the amount of crime dissuaded her from wanting to live in those areas out of convenience. After taking advantage of federal funding to help pay for school, Mary is a semester shy of getting a Masters Degree in Biomedical Science from Barry University.
“I’m trying to go to med school because that’s something I’ve always wanted to do and getting my Masters enhances my credentials in order to get there.” Being a single parent hasn’t been easy while working and going to school full-time.
“Today I had an exam and spent the entire weekend in the ER with my son who has the flu. Because I’m his mother, it’s my responsibility to take care of him and sit in the hospital until he gets the proper treatment. School is other people’s first priority – my son is my first priority.”
Here are the big stories on the agenda today:
Michael Jackson's new CD goes on sale today, and on Wednesday a documentary about his final days – with footage of his last rehearsals – debuts around the world.
The CD and the film are both called "This Is It." They're expected to rake in hundreds of millions of dollars for Jackson's estate.
As Kareen Wynter reports – Michael Jackson may be gone, but his legend lives on.
Washington (CNN) - Federal investigators have interviewed the pilots of a Northwest Airlines flight that overshot the airport in Minneapolis, Minnesota, last week, a National Transportation Safety Board spokesman said on Sunday.
The NTSB also said that flight attendants might be interviewed on Monday, and that it would not release further information for now.
Northwest Flight 188, carrying 144 people and five crew members, flew past Minneapolis-St. Paul International Airport during a mysterious 78 minutes of radio silence beginning about 7:56 p.m. ET Wednesday while en route from San Diego, California.
The Airbus 320 was over the Denver, Colorado, area when the radio silence began. Air traffic controllers re-established radio contact after the plane had flown about 150 miles past its destination.
