On this day last year, the Artemis I rocket and spacecraft lit up the sky and embarked on the revolutionary mission to the Moon and back. The first integrated flight test of the rocket and spacecraft continued for 25.5 days, validating NASA’s deep exploration systems and setting the stage for humanity’s return to the lunar surface.
On Nov. 16, 2022, the Space Launch System (SLS) rocket met or exceeded all expectations during its debut launch on Artemis I. The twin solid rocket booster motors responsible for producing more than 7 million pounds of thrust at liftoff reached their performance target, helping SLS and the Orion spacecraft reach a speed of about 4,000 mph in just over two minutes before the boosters separated.
Quite a few payloads caught a ride aboard the Orion spacecraft on the Artemis I mission: In addition to a number of small scientific satellites called CubeSats, a manikin named Commander Moonikin Campos sat in the commander’s seat. A Snoopy doll served as a zero-gravity indicator — something that floats inside the spacecraft to demonstrate microgravity.
During the mission, Orion performed two lunar flybys, coming within 80 miles of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles from our home planet, more than 1,000 times farther than where the International Space Station orbits Earth. This surpassed the record for distance traveled by a spacecraft designed to carry humans, previously set during Apollo 13.
The Orion spacecraft arrived back home to planet Earth on Dec. 11, 2022. During re-entry, Orion endured temperatures about half as hot as the surface of the Sun at about 5,000 degrees Fahrenheit. Within about 20 minutes, Orion slowed from nearly 25,000 mph to about 20 mph for its parachute-assisted splashdown.
Recovery teams successfully retrieved the spacecraft and delivered it back to NASA’s Kennedy Space Center for de-servicing operations, which included removing the payloads (like Snoopy and Commander Moonikin Campos) and analyzing the heat shield.
With the Artemis I mission under our belt, we look ahead to Artemis II — our first crewed mission to the Moon in over 50 years. Four astronauts will fly around the Moon inside Orion, practicing piloting the spacecraft and validating the spacecraft’s life support systems. The Artemis II crew includes: NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA astronaut Jeremy Hansen.

As we look ahead to Artemis II, we build upon the incredible success of the Artemis I mission and recognize the hard work and achievements of the entire Artemis team. Go Artemis!

NASA’s decision to scrub rocket launch disappointing, but right call: Canadian astronaut
NASA’s decision to scrub rocket launch disappointing, but right call: Canadian astronaut
Canadian astronaut David Saint-Jacques says today’s decision to scrub the launch of NASA‘s new moon rocket is disappointing but necessary due to another leak found ahead of the planned test flight.
The Artemis 1 mission, which aims to send an uncrewed NASA Orion spacecraft and Space Launch System rocket to the moon, was delayed after the rocket sprang a fuel leak, forcing controllers to call off…
"NASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the Moon and beyond with completion of a critical engine certification test series at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
The 12-test series represents a key step for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to build new RS-25 engines, using modern processes and manufacturing techniques, for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V."
At 1:47 a.m. EST on Nov. 16, 2022, our Orion spacecraft launched aboard the Space Launch System (SLS) rocket from historic Launch Complex 39B at NASA’s Kennedy Space Center in Florida on a path to the Moon, officially beginning the Artemis I mission.
This mission is the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, the SLS rocket, and Kennedy ground systems. This is the very first time this rocket and spacecraft have flown together, and it’s the first of many Artemis missions to the Moon. Artemis I is uncrewed, but it lays the groundwork for increasingly complex missions that will land humans on the lunar surface, including the first woman and the first person of color to do so.
With Artemis, we will build a long-term human presence on the Moon and prepare humanity for future exploration plans to Mars and beyond.

Managed to catch Artemis 1 from my backyard! It looked like the sun coming up! We could also see the booster separation, but unfortunately they didn’t show up on camera.
For comparison, here’s the Space X Crew-1 launch from November 15, 2020, shot in the same spot with the same phone:
The camera wouldn’t even focus on it. Tumblr won’t let me share more than one video at a time, but I was talking about “how bright” it looked. If only I knew then.
Best wishes to the whole Artemis team, you guys put on a great show!
