In this artist’s rendition, we explore a metallic world named Psyche, an asteroid that offers a unique window into the building blocks of planet formation. The NASA Psyche mission launches in 2023 and will arrive at the asteroid Psyche, which orbits the Sun between Mars and Jupiter, in 2026. The spacecraft, also named Psyche, will spend 21 months orbiting the asteroid, mapping it and studying its properties. The mission is led by Principal Investigator Lindy Elkins-Tanton of Arizona State University. NASA’s Jet Propulsion Laboratory is responsible for the mission’s overall management, system engineering, integration and test, and mission operations. Maxar Technologies is providing a high-power solar electric propulsion spacecraft chassis.

Is climate change the same as global warming? Not quite. The warming of Earth — or global warming — is just one factor that makes up a range of changes that are happening to our planet, which is climate change. And NASA is studying all of it: https://climate.nasa.gov/⁣⁣ ⁣⁣ Follow

Global sea levels are rising as a result of human-caused global warming, with recent rates being unprecedented over the past 2,500-plus years. @nasajpl's sea level rise expert Ben Hamlington explains how our warming planet is causing sea levels to rise.

North and South American are visible with the Atlantic and Pacific Oceans visualized in shades of yellow, orange, and red, representing the warming temperature of Earth's oceans.

On Nov. 16, 2022, the Orion spacecraft launched aboard the Space Launch System (SLS) rocket from @NASAKennedy Space Center and embarked on the #Artemis I mission to the Moon and back. Orion orbited the Moon, getting as close as 79 miles (127 km) to the lunar surface, and successfully splashed back down to Earth 25.5 days later on Dec. 11. Four RS-25 engines and two five-segment solid rocket boosters provided more than 8.8 million pounds (4 million kg) of thrust for SLS during liftoff and flight. Thanks in part to development of a new RS-25 engine controller that checks engine health 50 times per second, engineers were able to collect more than 100 measurements on pressures, temperatures, flows, speeds, and vibrations on the four RS-25 engines that helped power Artemis I. The preliminary post-flight data indicates that all SLS systems performed exceptionally and that the designs are ready to support a crewed flight on Artemis II. The Artemis II mission will bring us closer to establishing a sustained human presence on the lunar surface and landing the first woman and the first person of color on the Moon. This video was captured from the Launch Pad 39B perimeter and was used by engineers to monitor and track the rocket during flight.

We’re about to unveil the next astronauts to fly around the Moon. Will you join us? Three @NASAAstronauts and one @CanadianSpaceAgency astronaut will spend ten days in space on our upcoming #Artemis II mission, our first in more than 50 years to send humans around the Moon. Artemis II will prepare us for future Artemis missions that will land near the Moon’s South Pole and establish a long-term human presence on the lunar surface, getting us ready to send humanity to Mars. We’re introducing the Artemis II astronauts at a live @NASAJohnson event, starting 11 a.m. EDT (1500 UTC) on Monday, April 3—watch with us on NASA YouTube or nasa.gov/live to meet our Moon-bound crew.

Hey, remember that time we flew around the Moon and back?⁣ ⁣ That was pretty cool. Our #Artemis I mission launched on Nov. 16, 2022, and performed two lunar flybys over the course of a 25.5-day mission. At its farthest distance during the mission, Orion traveled nearly 270,000 miles (435,000 kilometers) from our home planet.⁣ ⁣ Artemis I was the first integrated test of NASA’s deep space exploration systems – the Orion spacecraft, SLS rocket, and the supporting ground systems – and the first in a series of increasingly complex missions at the Moon. Now with the first Artemis mission under our belt, we look forward to flying around the Moon again with Artemis II — this time, with astronauts.⁣ ⁣ Through Artemis missions, NASA will establish a long-term lunar presence for scientific discovery and prepare for human missions to Mars.⁣ ⁣

The planet’s thick CO2-filled atmosphere is great at trapping heat. This creates a runaway greenhouse effect that makes Venus roughly 700°F (389°C) hotter than it would be otherwise.
