NASA will make a second attempt to launch its powerful new Moon rocket on Saturday, after scrubbing a test flight earlier in the week, an official said Tuesday.

The highly anticipated uncrewed mission—dubbed Artemis 1—will bring the United States a step closer to returning astronauts to the Moon five decades after humans last walked on the lunar surface.

Mission manager Mike Sarafin, said the NASA team "agreed to move our launch date to Saturday, September the third."

Blastoff had been planned for Monday morning but was canceled because a test to get one of the rocket's four RS-25 engines to the proper temperature range for launch was not successful.

Astronomer Carl Sagan put it best: "We're made of star stuff." The atoms that make up the chemicals of our bodies didn't originate on Earth; they came from deep space. The big bang created hydrogen, helium, and a little bit of lithium, but heavier atoms—the ones essential for life—came from processes related to stars.

Scientists can now probe deeper. Which kinds of stellar processes produce which elements? And which kinds of stars are involved?

A new experiment called TIGERISS, envisioned for the International Space Station, aims to find out. TIGERISS has been chosen as the latest NASA Astrophysics Pioneers mission.

Pioneers are small-scale astrophysics missions that enable innovative investigations into cosmic phenomena. They may include experiments designed to fly on small satellites, scientific balloons, the space station, and payloads that could orbit or land on the Moon.

Earlier this year, the four previous Pioneers mission concepts, chosen in January 2021, were given the green light to move forward with construction and have been approved to fly later this decade.

"The Pioneer missions are an invaluable opportunity for early to mid-career scientists to conduct compelling astrophysics investigations, while gaining real experience in building space-based instrumentation," said Mark Clampin, director of the astrophysics division at NASA Headquarters in Washington.

NASA is preparing for their "Armageddon"-like mission of crashing a spacecraft into an asteroid, and they want the public to watch live.

Asteroids frequently get close to hitting Earth, but it's been over 65 million years since a catastrophic one has impacted our planet. Plus, there's been renewed interest in objects hurtling toward us since the popularity of the 2021 doomsday comedy "Don't Look Up."

Luckily, NASA will test out its plan in case it ever happens.

The space agency's Double Asteroid Redirection Test, or DART, will crash into the asteroid Dimorphos, which orbits a larger asteroid named Didymos, next month. Scientists say neither asteroid is headed towards Earth, but with Dimorphos at an estimated 520 feet long, it is an asteroid that could cause significant damage if it were to hit Earth, NASA says.

Regardless of the outcome, the mission will give astronomers and scientists "important data" on what the response would be should a dangerous asteroid have a collision course with Earth. There currently is no threat to us, scientists say.

"We don't want to be in a situation where an asteroid is headed toward Earth and then have to be testing this kind of capability.

Engineers have repaired an issue affecting data from NASA's Voyager 1 spacecraft. Earlier this year, the probe's attitude articulation and control system (AACS), which keeps Voyager 1's antenna pointed at Earth, began sending garbled information about its health and activities to mission controllers, despite operating normally. The rest of the probe also appeared healthy as it continued to gather and return science data.

The team has since located the source of the garbled information: The AACS had started sending the telemetry data through an onboard computer known to have stopped working years ago, and the computer corrupted the information.
