Alan Bean, the fourth man to walk on the moon who later chronicled the experience as an artist, died Saturday in Houston after a short illness. He was 86.

Bean was the lunar module pilot of Apollo 12, which made the second moon landing, in 1969.

Mikayla Sharrieff, India Skinner and Bria Snell should only be proud this week.

The 17-year-olds, all juniors at Benjamin Banneker High School in Washington, D.C., created a simple way using copper shards, drinking straws and filter floss — simple, though I am not smart enough to understand it — to demonstrate how to purify water in school drinking fountains that may be contaminated by lead.

They tested and even tasted the water. Their rudimentary purifier works.

NASA's InSight lander is on its way to Mars, after a successful launch on Saturday morning.

The lander was launched by an Atlas V rocket taking off from Vandenberg Air Force Base in California shortly after 4 a.m. local time. It successfully separated from the upper stage more than an hour later.

The lander is in contact with mission control as it heads off on its six-month trip to the Red Planet.

A critical part of NASA's next $2 billion rover mission to Mars broke during testing earlier this month.

The Mars 2020 mission's heat shield was undergoing stress-testing when it developed a crack that appeared around its entire circumference. The shield is designed to protect the rover as it enters the Martian atmosphere.

As part of a project to find the best edible plants to grow in space, NASA has turned to South Florida students.

High school and middle schoolers participating in the Fairchild Challenge educational competition are helping select food plants appropriate for growing aboard a spacecraft by conducting plant experiments, specially designed through the Growing Beyond Earth partnership between the space agency and the Fairchild Tropical Botanical Garden. 

If signs of life are found on a planet beyond our solar system sometime in the next decade, they'll most likely be on a planet discovered by a NASA satellite that's scheduled to launch on Monday.

Nothing conveys the excitement of space exploration like pictures from another planet. Now NASA is planning to go one better than pictures. The space agency is aiming to launch a probe carrying a communication system that will let future missions to Mars transmit live, high definition video to Earth.

The Trump administration’s $19.9 billion budget for NASA calls for privatizing the International Space Station. Senator Bill Nelson is blasting the proposed budget.

The budget proposal provides nearly $10 billion to support human space exploration of the moon. It pays for the Space Launch System and Orion capsule, that will launch from Kennedy Space Center, slated for a mission to the moon in 2020.

A rocket more powerful than any other flying today is scheduled to blast off Tuesday for the first time, if all goes well.

Here's a reminder that while you are out in the world buying groceries, picking up dry cleaning or catching up on The Crown, NASA's Mars rover Curiosity is on the red planet doing work.

Nestled among palm trees at the Huntington Library, Art Collections and Botanical Gardens near Pasadena, Calif., there's a mysterious, metallic structure that curls like a nautilus shell. It's called the Orbit Pavilion, and it was created by a team of artists at NASA's Jet Propulsion Laboratories, or JPL.

Step inside the 17-foot-tall structure and you'll hear otherworldly sounds triggered by the tracking signal of 19 orbiting satellites above Earth.

President Trump has formally told NASA to send U.S. astronauts back to the moon.

"The directive I'm signing today will refocus America's space program on human exploration and discovery," he said.

Standing at the president's side as he signed "Space Policy Directive 1" on Monday was Apollo 17 astronaut Harrison Schmitt, one of the last two humans to ever walk on the moon, in a mission that took place 45 years ago this week.

Snacks? Check. Bottled water? Check. Orion capsule?

Check.

At the Kennedy Space Center, in Cape Canaveral, Fla., 120 people settled in to wait out Hurricane Irma and oversee some of the nation's premier space technology. That includes the Orion Multi-Purpose Crew Vehicle capsule. The four-person spacecraft — now in development — is intended to carry astronauts to the moon and beyond.

President Trump's pick for the next leader of NASA is a fighter pilot who wants Americans to return to the moon but doesn't believe that humans are causing climate change.

Scientists are about to get an up-close and personal look at the planet Jupiter's most famous landmark, the Great Red Spot.

NASA's Juno spacecraft will be directly over the spot shortly after 10 p.m. ET Monday, July 10, about 5,600 miles above the gas giant's cloud tops. That's closer than any spacecraft has been before.

The spot is actually a giant storm that has been blowing on Jupiter for centuries. It's huge, larger than Earth in diameter.
