This nighttime picture of Earth was taken on April 2, 2026, by an Artemis II crew member aiming a camera through a window of the Orion spacecraft. The image was captured after Orion completed its translunar injection burn, the critical maneuver that sent the spacecraft on its path toward the Moon and back.

NASA’s Space Launch System rocket carrying the Orion spacecraft with NASA astronauts Reid Wiseman, commander; Victor Glover, pilot; Christina Koch, mission specialist; and CSA (Canadian Space Agency) astronaut Jeremy Hansen, mission specialist onboard launches on the Artemis II mission, Wednesday, April 1, 2026, from Launch Complex 39B at NASA’s Kennedy Space Center in Florida.

Four astronauts aboard NASA’s Orion spacecraft atop the SLS (Space Launch System) rocket launch on the agency’s Artemis II test flight, Wednesday, April 1 from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. Artemis II lifted off at 6:35 p.m. ET. Artemis II is the first crewed mission of the agency’s Artemis campaign. The mission will send NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch and CSA (Canadian Space Agency) astronaut Jeremy Hanson on an approximately 10-day journey around the Moon and back to Earth.

The Orion Crew Survival System suits that Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, and Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency) will wear on the Artemis II test flight are seen in the suit-up room of the Neil A. Armstrong Operations and Checkout Building, Saturday, Jan. 17, 2026, at NASA’s Kennedy Space Center in Florida.

For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979. On March 15, Arctic sea ice extent reached 5.52 million square miles (14.29 million square kilometers), very close to the 2025 peak of 5.53 million square miles (14.31 million

NASA’s IXPE observed the outer rim of the supernova remnant highlighted in purple in the inset. Data from IXPE is combined with data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton.

Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence

Captured Nov. 29, 2024 by NASA’s James Webb Space Telescope, this infrared view of Saturn shows its glowing icy rings and layered atmosphere. Several moons are visible, including Janus, Dione, and Enceladus.

For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82.

Moon rocks are seen during a March 24, 2026, event where NASA is outlining how the agency is executing the National Space Policy and accelerating preparations for America’s return to the surface of the Moon by 2028.

As NASA seeks to understand the mysteries of the universe, the agency is advancing technologies to locate and explore Earth-like planets far beyond our solar system. A key element of this research involves observing reflected light from exoplanets, which can reveal indicators of Earth-like features such as water and oxygen. However, detecting this faint reflected

This new image from the Hubble Space Telescope and the James Webb Space Telescope takes a closer look at the core of Messier 101, also known as the Pinwheel Galaxy.

Editor’s Note: This article was originally published on April 25, 2022 and has been updated to reflect changes including the completion of Hangar One’s restoration. Restoration has been completed on Hangar One, a historic landmark in the San Francisco Bay Area and a key part of the region’s early aviation history. In December 2025, Planetary Ventures completed restoration of

NASA astronaut and Expedition 74 crew member Chris Williams smiles for the camera during a spacesuit fit verification inside the International Space Station’s Quest airlock.

Airflow around rockets as they travel from Earth into space can have a dramatic impact on a mission, which is why NASA used advanced simulations to provide the best possible launch conditions for the Artemis II test flight around the Moon. To better understand the Artemis Space Launch System (SLS) rocket’s flight environment, engineers turned to a NASA-developed tool called the Launch, Ascent, and Vehicle Aerodynamics

Commercial launch providers continue to advance propulsion technology with a renewed focus on liquid oxygen and methane propelled rockets and spacecraft. As systems grow in scale, carrying millions of pounds of propellant, so too does the responsibility to fully understand the safety profile. Engineers at NASA, with decades of cryogenic and test operations expertise, are
