NASA Artemis I Moon Mission Lifts Off: First Anniversary

NASA Artemis I Moon Mission Lifts Off: First Anniversary

NASA's Space Launch System lifts off from the launch pad, illuminating the ground with a bright white light that bounces off of clouds of smoke. Pictured on the left side of this image is the liquid hydrogen "flare stack" where vented liquid hydrogen is burned off safely.

In this photo, NASA’s Space Launch System (SLS), carrying the Orion spacecraft, lifts off the pad at Launch Complex 39B at the agency’s Kennedy Space Center in Florida at 1:47 a.m. EST on Nov. 16, 2022. Set on a path to the Moon, this officially began the Artemis I mission.

Over the course of 25.5 days, Orion performed two lunar flybys, coming within 80 miles (129 kilometers) of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles (435,000 kilometers) from our home planet. On Dec. 11, 2022, NASA’s Orion spacecraft successfully completed a parachute-assisted splashdown in the Pacific Ocean at 12:40 p.m. EST as the final major milestone of the Artemis I mission.

Artemis I was the first in a series of increasingly complex missions that will enable human exploration at the Moon and future missions to Mars. Following the success of Artemis I, humans will fly around the Moon on Artemis II.

Farther & Faster: NASA's Journey to The Moon with Artemis I

Farther & Faster: NASA's Journey to The Moon with Artemis I

At 1:47 a.m. EST (6:47 UTC) on Nov. 16, 2022, NASA’s Orion spacecraft launched atop the Space Launch System (SLS) rocket from historic Launch Pad 39B at NASA’s Kennedy Space Center in Florida on a path to the Moon, officially beginning the Artemis I mission.

Over the course of 25.5 days, Orion performed two lunar flybys, coming within 80 miles (129 kilometers) of the lunar surface. At its farthest distance during the mission, Orion traveled nearly 270,000 miles (435,000 kilometers) from our home planet. On Dec. 11, 2023, NASA’s Orion spacecraft successfully completed a parachute-assisted splashdown in the Pacific Ocean at 9:40 a.m. PST (12:40 p.m. EST) as the final major milestone of the Artemis I mission.

Artemis I set new performance records, exceeded efficiency expectations, and established new safety baselines for humans in deep space. This is a prelude to what comes next—following the success of Artemis I, human beings will fly around the Moon on Artemis II.

We have demonstrated our ability to go farther and faster than ever before, opening the door to explore Mars and other destinations throughout the solar system. This is the story of Artemis I.

New NASA Artemis V Moon Rocket Engine Test: Preparing for Crewed Missions

New NASA Artemis V Moon Rocket Engine Test: Preparing for Crewed Missions

NASA has conducted the second hot fire in a final 12-test certification series paving the way for production of new RS-25 engines to help power NASA's Space Launch System rocket for future Artemis missions to the Moon and beyond. An Aerojet Rocketdyne RS-25 rocket engine (RS-25 developmental engine E0525) was tested on the Fred Haise Test Stand (formerly A-1 Test Stand) at the John C. Stennis Space Center in Mississippi, on November 15, 2023, at 15:45 EST. This was the second hot fire test out of the 12 planned in the final round of certification testing ahead of production of an updated set of engines for NASA’s Space Launch System (SLS) that will be used beginning with Artemis V. The test had a planned duration of 500 seconds with the RS-25 engine running up to 113% power level—more than the level needed to power SLS.

Meet the Perseverance Rover's Mars Samples: "Otis Peak" | NASA/JPL

Meet the Perseverance Rover's Mars Samples: "Otis Peak" | NASA/JPL

Meet the 20th Martian sample collected by NASA’s Mars Perseverance rover—“Otis Peak,” the first rock core sample taken from a conglomerate rock, that consists of pebbles cemented together.

This sample is referred to as a “treasure box” because the pebbles are believed to have been carried by a fast-moving river from places the rover may never explore. Scientists believe studying this sample may yield information about the formation and environmental evolution of Jezero Crater.

As of early November 2023, the Perseverance rover has collected and sealed 23 scientifically selected samples inside pristine tubes as part of the Mars Sample Return campaign. The next stage is to get them to Earth for study.

Considered one of the highest priorities by the scientists in the Science and Astrobiology Decadal Survey 2023-2032, Mars Sample Return would be the first mission to return samples from another planet and provides the best opportunity to reveal the early evolution of Mars, including the potential for ancient life. NASA is teaming with the European Space Agency (ESA) on this important endeavor.

A key objective for Perseverance's mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet's geology and past climate, pave the way for human exploration of the Red Planet, as well as be the first mission to collect and cache Martian rock and regolith (broken rock and dust).

How Your Name Can Fly Aboard NASA’s Europa Clipper to Jupiter | JPL

How Your Name Can Fly Aboard NASA’s Europa Clipper to Jupiter | JPL

Go behind the scenes in the Microdevices Laboratory at NASA’s Jet Propulsion Laboratory in Southern California to see how your name could be sent to Jupiter’s moon Europa as part of NASA’s “Message in a Bottle” campaign. Names will be stenciled in tiny letters on special microchips that will ride aboard the Europa Clipper spacecraft as it journeys 1.8 billion miles (2.6 billion kilometers) to the icy moon.

To sign, go to:

https://go.nasa.gov/MessageInABottle  

See how technicians will use an electron beam to stencil names onto microchips, where each line of text is smaller than 1/1000th the width of a human hair. The microchips will be attached to a metal plate engraved with the original poem “In Praise of Mystery,” written by U.S. Poet Laureate Ada Limón to celebrate the mission. That plate will then be attached to the exterior of the Europa Clipper spacecraft.

NASA’s Europa Clipper mission aims to determine whether Europa has conditions that could support life. Once spacecraft assembly has been completed at JPL, the orbiter will be shipped to NASA’s Kennedy Space Center in Florida in preparation for launch in October 2024.

You can add your name to the “Message in a Bottle” campaign through Dec. 31, 2023.

Planet Mars: Exploring Aram Chaos | NASA's Mars Reconnaissance Orbiter

Planet Mars: Exploring Aram Chaos | NASA's Mars Reconnaissance Orbiter

Aram Chaos is an eroded impact crater on Mars, about 280 kilometers in diameter. The floor of Aram Chaos also contains huge blocks of collapsed (chaotic) terrain that formed when water or ice was catastrophically removed. The crater was also filled in with sediments over time. This observation was acquired to fill in High Resolution Imaging Science Experiment (HiRISE) coverage where Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) data already exists. CRISM is another instrument onboard the Mars Reconnaissance Orbiter. 

The saying Λάθε βιώσας (“live hidden”) is attributed to Epicurus. Aram Chaos would be a good place to hide. (We used Modern Greek pronunciation to render the transliteration in the title card as “láthe viósas.”)

This is a non-narrated clip with ambient sound. Enhanced color image is less than 1 km (under a mi) across and the spacecraft altitude was 272 km (169 mi). For full images including scale bars, visit the source link.

Mars Reconnaissance Orbiter (MRO) is a spacecraft designed to study the geology and climate of Mars, to provide reconnaissance of future landing sites, and to relay data from surface missions back to Earth. It was launched on August 12, 2005, and reached Mars on March 10, 2006. 

The University of Arizona, Tucson, operates the HiRISE instrument, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA's Jet Propulsion Laboratory (JPL), a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.

“For 17 years, MRO has been revealing Mars to us as no one had seen it before,” said the mission’s project scientist, Rich Zurek of JPL.

Blooming of The "Spare Tire" Nebula: IC 5148 | Gemini South Telescope

Blooming of The "Spare Tire" Nebula: IC 5148 | Gemini South Telescope

IC 5148, nicknamed the Spare Tire Nebula, is a beautiful planetary nebula located about 3,000 light-years away near the ‘neck’ of the southern constellation Grus (The Crane). This image, captured with the Gemini South telescope, one half of the International Gemini Observatory operated by the National Science Foundation's NOIRLab, showcases the looming cloud of gas of IC 1548 and the central stellar remnant from which the gas radiates. It is one of the fastest expanding planetary nebulae, pushing out into space at 180,000 kilometers per hour (112,000 miles per hour).

With small telescopes, this nebula looks like a bright central star with an outer ring. The mesmerizing layers of gas are faint. They are almost undetectable without the use of larger telescopes, and not with the clarity captured in this image using the Gemini Multi-Object Spectrograph (GMOS) on Gemini South. Around the time IC 5148 was discovered by astronomers in 1894, researchers coined the term planetary nebula to refer to these giant gaseous balls that looked like giant planets. Today we know that these balls are in fact stellar remnants.

At the center of IC 5148 is a white dwarf, the hot core of the dying star, surrounded by asymmetrical gaseous ‘blooms’ and a faint halo ring. The predecessor of the white dwarf was likely a star of a similar mass to our Sun. At the end of that star’s life, the internal pressure imbalance resulted in the star swelling up into a red giant. As it grew, the outer layers of the gas and stellar material were pushed into space to form the nebula we see today. The central hole—the dark patch surrounding the star—is due to the pressure of the radiation from the star that pushes the surrounding gas away from the core and leaves a vacant space. The formation of the ring and the bow-like structures of gas are marks of the evolutionary history of IC 5148—but the mechanisms that created them remain a mystery to astronomers.

The International Gemini Observatory consists of twin 8.1-meter diameter optical/infrared telescopes located on two of the best observing sites on the planet. The Gemini South telescope is located on a mountain in the Chilean Andes called Cerro Pachón, where very dry air and negligible cloud cover make this another prime telescope location. Both of the Gemini telescopes have been designed to excel in a wide variety of optical and infrared capabilities. By incorporating technologies such as laser guide star adaptive optics and multi-object spectroscopy, astronomers in the Gemini partnership explore the universe in unprecedented depth and detail.
