NASA’s crawler-transporter 2 carrying the agency’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft, secured to the mobile launcher, begins the 4.2-mile journey toward Launch Complex 39B at NASA’s Kennedy Space Center in Florida on 01/17/2026. The Artemis II test flight will take Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, and Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency), around the Moon and back to Earth no later than April 2026.

The AVATAR (A Virtual Astronaut Tissue Analog Response) investigation will use organ-on-a-chip devices, or organ chips, to study the effects of deep space radiation and microgravity on human health. The chips will contain cells from Artemis II astronauts and fly side-by-side with crew on their approximately 10-day journey around the Moon. This research, combined with other studies on the health and performance of Artemis II astronauts, will give NASA insight into how to best protect astronauts as exploration expands to the surface of the Moon, Mars, and beyond.

The James Webb Space Telescope is doing something astronomers dreamed about for decades: peering into our universe’s early past, a period known as cosmic dawn. A new NASA documentary—also called Cosmic Dawn—chronicles the inside story of Webb’s design, construction, and launch. John Mather, who won the 2006 Nobel Prize for Physics, proposed the telescope and led its science team for decades. In this interview, Mather talks about his life, his research, and the pre-dawn phone call telling him he had won the Nobel Prize.

July will see the launch of the groundbreaking Solar EruptioN Integral Field Spectrograph mission, or SNIFS. Delivered to space via a Black Brant IX sounding rocket, SNIFS will explore the energy and dynamics of the chromosphere, one of the most complex regions of the Sun’s atmosphere. The SNIFS mission’s launch window at the White Sands Missile Range in New Mexico opens on Friday, July 18.

This animation depicts NASA's Mars Reconnaissance Orbiter performing a 120-degree roll that increases the strength of its radar signal by 10 times or more.

NASA's Curiosity Mars rover captured this scene while looking out across a region filled with boxwork patterns, low ridges that scientists think could have been formed by groundwater billions of years ago.

This video shows SPHEREx's field of view as it scans across one section of sky inside the Large Magellanic Cloud, with rainbow colors representing the infrared wavelengths the telescope's detectors see.

What does the future of space exploration look like? At the 2025 FIRST Robotics World Championship in Houston, NASA gave student robotics teams and industry leaders a first-hand look—complete with lunar rovers, robotic arms, and real conversations about shaping the next era of discovery. NASA engaged directly with the Artemis Generation, connecting with more than

NASA's Curiosity Mars rover captured these drifting noctilucent, or twilight, clouds in a 16-minute recording on Jan. 17, 2025.

Lee esta nota de prensa en español aquí. Earth’s average surface temperature in 2024 was the warmest on record, according to an analysis led by NASA scientists. Global temperatures in 2024 were 2.30 degrees Fahrenheit (1.28 degrees Celsius) above the agency’s 20th-century baseline (1951-1980), which tops the record set in 2023. The new record comes after

NASA has taken a big step forward in how engineers will assemble and stack future SLS (Space Launch System) rockets for Artemis Moon missions inside the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. The VAB’s High Bay 2 has been outfitted with new tooling to facilitate the vertical integration of

Black holes are mysterious, far away, and can bend the fabric of reality itself—but we're learning more about them all the time. Ronald Gamble, a NASA theoretical astrophysicist, uses math, computer coding, and a dash of creativity to peer inside some of the universe's most extreme objects. We'll explore what it would feel like to get pulled into a black hole and what people get wrong about black holes. And we'll answer questions from curious listeners, including, "What would happen if a black hole ate nothing but magnetized material?"

NASA's InSight Mars lander acquires the same reddish-brown hue as the rest of the planet in a set of images from 2018 to 2024 that were captured by the agency's MRO HiRISE camera.

NASA's Perseverance Mars Rover used its Mastcam-Z camera system to capture this panorama of a location nicknamed Pico Turquino Hills on Oct. 22, 2024.

This animation captured from NASA's rover driving software depicts the agency's Perseverance during a slippery drive as it ascends toward the rim of Mars' Jezero Crater on Oct. 16, 2024.

A team at NASA’s Glenn Research Center in Cleveland streamed 4K video footage from an aircraft to the International Space Station and back for the first time using optical, or laser, communications. The feat was part of a series of tests on new technology that could provide live video coverage of astronauts on the Moon

As part of NASA’s efforts to expand commercial resupply in low Earth orbit, Sierra Space’s uncrewed spaceplane arrived at NASA’s Kennedy Space Center in Florida ahead of its first flight to the International Space Station. The Dream Chaser spaceplane, named Tenacity, arrived at Kennedy on May 18 inside a climate-controlled transportation container from NASA’s Neil Armstrong

In this special episode, we turn the tables and put host Padi Boyd in the interview seat. Padi shares stories from her time with NASA’s groundbreaking Kepler mission, which showed us many more exoplanets—planets orbiting other stars—than we had previously discovered. She also tells us about her dream astronomical dinner companion and her go-to karaoke song. Plus, we'll wrap up another season of wild and wonderful adventures by answering questions from listeners like you and sharing behind-the-scenes tidbits from Season 6 episodes. For the first time, this episode of Curious Universe is also available as a video podcast. Check it out at nasa.gov/curiousuniverse and NASA’s YouTube channel: youtu.be/h0wLZJeYGxw
