NASA Discoveries, R&D, Moon to Mars Exploration Plans Persevere This Year @NASA – December 21, 2020
|
In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.
“NASA has impressed the nation with our resilience and persistence during the pandemic,” said NASA Administrator Jim Bridenstine. “We made history with a U.S. commercial partner, made groundbreaking discoveries, advanced science, furthered aeronautics research and technology development, and even joined in the fight against COVID-19. We met an incredibly challenging year with incredible achievements and established a path for continued success.”
The space agency’s aid to the federal pandemic response included development of a surface decontamination system, a ventilator developed by engineers in just 37 days, and an oxygen helmet to treat COVID-19 patients.
In 2020, astronauts launched from American soil to the International Space Station for the first time since 2011 and, for the first time ever, on an American commercial spacecraft. The return of crewed launches to U.S. shores arrived during the 20th year of a continuous human presence aboard the space station, enabling more critical science to prepare for future Artemis missions.
NASA advanced its plan for a robotic and human return to the Moon under the Artemis program, is on track for its first two robotic deliveries next year, named astronauts to the Artemis Team, and identified science priorities and activities for the Artemis III mission to land the first woman and next man on the lunar surface in 2024.
Robotic and human exploration go hand-in-hand, with the former leading the way to smarter, safer human missions. NASA launched its Mars 2020 Perseverance rover mission to the Red Planet in July, and it’s now more than halfway to its destination. Track the rover’s journey in real time using the Eyes on the Solar System application.
NASA took a major step in solidifying international cooperation for exploration with the signing of the Artemis Accords between NASA and eight partner countries. The accords implement the Outer Space Treaty and other international agreements to establish a set of principles to guide cooperation among nations participating in the agency’s lunar exploration plans, such as the full, timely, and public release of scientific data. By committing to the principles of the Artemis Accords, NASA and its partners help ensure humanity can enjoy a peaceful and prosperous future in space.
In a first for NASA, the Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft briefly touched and collected samples from the asteroid Bennu Oct. 20. The samples will return to Earth in 2023.
The James Webb Space Telescope, the agency’s next great observatory, made progress toward its launch in 2021, now targeted for Oct. 31.
Moon to Mars
Throughout the decade, NASA will send new science instruments and technology demonstrations to study the Moon, send astronauts to the lunar surface beginning in 2024 and about once per year thereafter, and will establish sustainable lunar exploration with our commercial and international partners. This year, NASA:
- Transported the core stage for the Space Launch System (SLS) rocket in early January from NASA’s Michoud Assembly Facility in New Orleans to the agency’s Stennis Space Center near Bay St. Louis, Mississippi, where engineers are conducting the Green Run test series.
- Completed a structural testing series to evaluate the upper part of the SLS rocket and four of the core stages structures, ordered 18 additional RS-25 rocket engines and additional boosters, continued manufacturing rockets for Artemis II and III, and fired up a flight support booster for future SLS missions.

- Finished modifications and upgrades to prepare Launch Pad 39B at Kennedy Space Center in Florida for Artemis missions. Exploration Ground Systems teams also simulated portions of the launch countdown, prepared for the tanking process with a simulated launch, and started stacking the rocket for the Artemis I launch.
- Completed a rigorous test campaign with the Orion spacecraft, installed four solar array wings and fitted three spacecraft adapter jettison fairing panels, attached the forward bay cover to the spacecraft for the Artemis I mission, and continued manufacturing spacecraft for Artemis II and III.
- Completed a set of technical lander studies to pave the way for a human landing system (HLS) solicitation. NASA has since partnered with three companies – Blue Origin Federation, Dynetics, and SpaceX – to advance their HLS designs. All three companies recently passed a certification baseline review that finalized functional and performance requirements.
Plans to develop the Gateway in lunar orbit reached several milestones.
- The agency awarded Northrop Grumman a contract to develop the Habitation and Logistics Outpost (HALO), which will be a crew cabin for the lunar outpost. HALO and the Power and Propulsion Element will launch to space together as the foundation for the initial Gateway capability.
- When it launches, Gateway will carry two space weather instruments to help forecast weather for future crew missions. SpaceX, the first company to receive a resupply contract, will deliver new experiments and other supplies.
- NASA finalized two of three anticipated agreements with international partners for Gateway contributions and expects to complete the third within a month. Under its agreement, which was finalized in October, ESA (European Space Agency) will provide a large habitation module, as well as a refueling module and advanced communications. The Canadian Space Agency, which finalized its agreement in November, will provide the Gateway’s external robotics system, including the next generation robotic arm, Canadarm3, and robotic interfaces for the Gateway modules to enable payload installation.
To prepare for future crew missions, the agency:
- Hosted in January its first public astronaut graduation, welcoming 11 members to its corps. Several of NASA’s newest astronauts were among the 18 named to the agency’s Artemis Team in December.
- Announced a call to #BeAnAstronaut candidate, garnering more than 12,000 applications for the next Artemis Generation astronauts. NASA will select the most qualified candidates in late 2021.
- Studied crew members at three different mission durations aboard the space station and continued to use analogs in the United States and in Germany to provide data on isolation and other conditions.
Science and technology progress for Artemis includes:
- As part of its Commercial Lunar Payload Services (CLPS) initiative, the agency assigned a suite of payloads to the first two commercial Moon deliveries set to land on the Moon in 2021, and awarded task orders to Masten Space Systems, Intuitive Machines, and Astrobotic.
- NASA and partners matured a drill and water-measuring payload called PRIME-1 for lunar delivery in 2022, instruments that will also be part of the agency’s VIPER rover.
- Following an earlier announcement, NASA released its first call for Payloads and Research Investigations on the Surface of the Moon, or PRISM, and collected responses in early December.
- Introduction of the Artemis Base Camp concept, which calls for the infrastructure NASA and its partners will need to establish a sustainable human presence on the Moon.
-
Industry input on rover concepts for both humans and robots.
- NASA selected four companies to collect a small amount of lunar regolith from the Moon and transfer ownership of it to NASA as an early demonstration of a public-private partnership for in-situ resource utilization.
The agency outlined how investing in the Moon today prepares for exploration tomorrow.
- The Mars 2020 Perseverance rover, named in an essay contest, will seek signs of ancient life and collect samples to send back to Earth.
- Perseverance is carrying a number of critical instruments and technologies, including an investigation to study spacesuit materials and a new method of producing oxygen from carbon dioxide. Sensors on the spacecraft also are prepared to collect data during landing while an autopilot technology called terrain relative navigation will help the rover touchdown safely on the Red Planet in February 2021.
- Also onboard the rover is the Ingenuity Helicopter, which will be the first aircraft to attempt controlled flight on another planet.
