Breaking Records, Returning Asteroid Samples Among NASA’s Big 2023

In 2023, as NASA pushed the limits of exploration for the benefit of humanity, the agency celebrated astronaut Frank Rubio becoming the first American astronaut to spend more than one year in space; delivered samples from an asteroid to Earth; sent a spacecraft to study a metal-rich asteroid for the first time; launched multiple initiatives to share climate data; advanced developments in sustainable aircraft; all while continuing preparations to send the first Artemis astronauts to the Moon.

“This year, NASA continued to make the impossible, possible while sharing our story of discovery with the world,” said NASA Administrator Bill Nelson. “We’ve launched missions that are helping tell the oldest stories of our solar system; continued to safely transport astronauts to the International Space Station to conduct groundbreaking science; our Earth satellites are providing critical climate data to all people; we’re making great strides to make aviation more dependable and sustainable; and we’re growing our commercial and international partnerships as we venture back to the Moon and on to Mars. NASA is home to the world’s finest workforce, and there is no limit to what we can achieve when we work together.”

In support of the Biden-Harris Administration’s efforts to address climate change, NASA is leading the development of U.S. government-wide initiatives focused on bringing Earth science information to the public. The Earth Information Center, a new interactive exhibit at NASA Headquarters in Washington, also includes an online experience that invites visitors to see Earth as NASA sees it from space while providing critical data needed by researchers and policymakers.

Among other notable mentions, the agency’s James Webb Space Telescope – the largest, most powerful telescope humanity has ever put in space – celebrated one year of science. NASA and the Defense Advanced Research Projects Agency (DARPA) announced the two organizations will partner on DRACO (Demonstration Rocket for Agile Cislunar Operations) to test a nuclear-powered rocket in space as soon as 2027.

This year NASA celebrated 25 years of International Space Station operations as the agency continued to foster the growth of the commercial space economy, supporting the development of commercial space station partnerships. It also marks the 65th anniversary of the agency. While celebrating these achievements, NASA also unveiled its NASA 2040 vision for the agency to ensure it remains a global leader in aerospace for decades to come.

Below are additional highlights of NASA’s endeavors in 2023 to explore the unknown in air and space, innovate for the benefit of humanity, and inspire the world through discovery.

Understanding Our Changing Planet

NASA has used its unique vantage point of space to better understand our changing planet since launching its first Earth science satellites in the 1960s. In 2023, NASA’s Office of the Chief Scientist established a cross-agency working group and released a climate strategy. Other agency efforts to share scientific data on Earth.gov and other areas include:

• Working with its partners, NASA launched the U.S. Greenhouse Gas Center, opening access to trusted data on greenhouse gases.
  • Data from NASA’s Earth Surface Mineral Dust Source Investigation (EMIT) instrument aboard the International Space Station is part of the gas center. EMIT identifies point-source emissions of greenhouse gases with a proficiency greater than expected.
• NASA’s tracking of greenhouse gases includes both global and focused estimates.
• Building on the month-by-month worldwide temperature data collected and released by NASA and National Oceanic and Atmospheric Administration both agencies are expected to announce soon 2023 was the warmest year in recorded history.
• A NASA airborne campaign helped show that methane ‘hot spots’ in the Yukon-Kuskokwim Delta are more likely to be found where recent wildfires burned into the tundra, altering carbon emissions from the land.
• After successfully launching to space earlier this year, NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) mission to study air quality now is successfully transmitting information about major air pollutants over North America.
• NASA’s SWOT (Surface Water and Ocean Topography) mission offered the its first detailed perspectives of Earth’s surface water.
• Among natural hazards, NASA data was put to use in monitoring the heavy rains occurring in the drought-stricken areas, heat waves, wildfires, and subsequent health affects worldwide, as well as expansion of NASA landslide data.

Advancing Moon to Mars Exploration

This year, NASA shared results of its first Moon to Mars Architecture Concept Review as it builds a blueprint for human exploration throughout the solar system for the benefit of humanity. The agency also continues to take significant steps toward landing the first woman and first person of color on the Moon as part of Artemis. Notably in 2023, NASA announced crew for the Artemis II mission, the first Artemis mission with astronauts around the Moon and back to Earth. The crew completed fundamentals training, and is now focusing on training for mission operations. Additional highlights for human deep space exploration include:

• All major elements for the SLS (Space Launch System) rocket for Artemis II are complete or nearing completion including booster segments delivered to NASA’s Kennedy Space Center in Florida and final core state assembly testing at NASA’s Michoud Assembly Facility in New Orleans.

• The solid rocket booster segments and the four RS-25 engines are complete for the Artemis III SLS, as well as three of the five major core stage elements. Teams are integrating elements of Orion’s crew module, and the European Service Module.
• NASA selected the geology team to develop a lunar surface science plan for Artemis III.  
• Beyond Artemis III, teams completed welding the primary structure for Gateway’s HALO (Habitation and Logistics Outpost), where astronauts will live and work in lunar orbit. Fabrication is complete on the primary structure of the Power and Propulsion Element that will provide power, communications, and maintain Gateway’s orbit.
• In addition to other hardware assembly and certification work for later missions, Artemis V will include a lunar terrain vehicle. NASA asked SpaceX to further develop Starship for Artemis IV, and also selected Blue Origin to develop a human lunar lander for Artemis V.
• Experiments aboard the International Space Station focused on helping astronauts go farther and stay longer in space. This research included growing sustainable crops such as dwarf tomatoes, understanding how microbes adapt to space to protect crew health, and developing innovative materials that can weather the harsh environments of the Moon and Mars.

To support future NASA Moon missions with crew, the agency’s CLPS (Commercial Lunar Payload Services) initiative is in the final phases of preparations for the first two launches and landings to deliver NASA science and technology demonstrations to the lunar surface.

• Five NASA payloads are aboard Astrobotic’s Peregrine Mission 1 lander, which is set to launch no earlier than Monday, Jan. 8. Soon after, another six NASA payloads will launch no earlier than Friday, Jan. 12, aboard Intuitive Machine’s Nova-C spacecraft.
• Since launching CLPS, NASA has contracted with five companies for eight deliveries to the lunar surface. Most recently in 2023, NASA selected Firefly Aerospace for a delivery.
• Among future CLPS payloads is NASA’s first robotic lunar rover, VIPER – short for the Volatiles Investigating Polar Exploration Rover. The rover will trek into permanently shadowed areas to unravel the mysteries of the Moon’s water and better understand the environment. In preparation for a landing in late 2024, scientists named VIPER’s mission area in honor of NASA mathematician Melba Roy Mouton. Development, assembly and testing also continues for the rover’s solar and battery systems.

While NASA is leading Artemis, international partnerships are a key part of advancing Moon to Mars exploration. In 2023, 10 additional countries signed the Artemis Accords, which lay out a common set of principles governing the civil exploration and use of outer space. So far, 33 countries have signed the Artemis Accords.
