Before Apollo astronauts set foot upon the Moon, much remained unknown about the lunar surface. While most scientists believed the Moon had a solid surface that would support astronauts and their landing craft, a few believed a deep layer of dust covered it that would swallow any visitors. Until 1964, no closeup photographs of the lunar surface existed, only those obtained by Earth-based telescopes.
NASA’s Jet Propulsion Laboratory in Pasadena, California, managed the Ranger program, a series of spacecraft designed to return closeup images before impacting on the Moon’s surface. Ranger 7 first accomplished that goal in July 1964. On Feb. 17, 1965, its successor Ranger 8 launched toward the Moon, and three days later returned images of the Moon. The mission’s success helped the country meet President John F. Kennedy’s goal of a human Moon landing before the end of the decade.

Ranger 8 lifted off from Cape Kennedy, now Cape Canaveral, Florida, on Feb. 17, 1965. The Atlas-Agena rocket first placed the spacecraft into Earth orbit before sending it on a lunar trajectory. The next day, the spacecraft carried out a mid-course correction, and on Feb. 20, Ranger 8 reached the Moon. The spacecraft’s six cameras turned on as planned, about eight minutes earlier than its predecessor to obtain images comparable in resolution to ground-based photographs for calibration purposes. Ranger 8 took its first photograph at an altitude of 1,560 miles, and during its final 23 minutes of flight, the spacecraft sent back 7,137 images of the lunar surface. The last image, taken at an altitude of 1,600 feet and 0.28 seconds before Ranger 8 impacted at 1.67 miles per second, had a resolution of about five feet. The spacecraft impacted 16 miles from its intended target in the Sea of Tranquility, ending a flight of 248,900 miles. Scientists had an interest in this area of the Moon as a possible landing zone for a future human landing, and indeed Apollo 11 landed 44 miles southeast of the Ranger 8 impact site in July 1969.

Television networks broadcast Ranger 9’s images of the Alphonsus crater and the surrounding area “live” as the spacecraft approached its impact site in the crater – letting millions of Americans see the Moon up-close as it happened. Based on the photographs returned by the last three Rangers, scientists felt confident to move on to the next phase of robotic lunar exploration, the Surveyor series of soft landers. The Ranger photographs provided confidence that the lunar surface could support a soft-landing and that the Sea of Tranquility presented a good site for the first human landing. A little more than four years after the final Ranger images, Apollo 11 landed the first humans on the Moon.

The impacts of the Ranger probes left visible craters on the lunar surface, later photographed by orbiting spacecraft. Lunar Orbiter 2 and Apollo 16 both imaged the Ranger 8 impact site at relatively low resolution in 1966 and 1972, respectively. The Lunar Reconnaissance Orbiter imaged the crash site in greater detail in 2012.

The Crew Health and Performance Exploration Analog (CHAPEA) team hosts a Media Day at NASA’s Johnson Space Center in Houston on April 11, 2023.Credit: NASA Media are invited to visit NASA’s simulated Mars habitat on Monday, March 10, at the agency’s Johnson Space Center in Houston. The simulation will help prepare humanity for future missions to the Red Planet.
This is the second of three missions as part of NASA’s CHAPEA (Crew Health and Performance Exploration Analog), set to begin in May 2025 when volunteer crew members enter the 3D printed habitat to live and work for a year.
During the mission, crew members will carry out different types of mission activities, including simulated “marswalks,” robotic operations, habitat maintenance, personal hygiene, exercise, and crop growth. Crew also will face planned environmental stressors such as resource limitations, isolation, and equipment failure.
The in-person media event includes an opportunity to speak with subject matter experts and capture b-roll and photos inside the habitat. Crew members will arrive for training at a later date and will not be available at this event.
To attend the event, U.S. media must request accreditation by 5 p.m. CDT Monday, March 3, and international media by 5 p.m., Monday, Feb. 24, via the NASA Johnson newsroom at: 281-483-5111 or jsccommu@nasa.gov. Media accreditation will be limited due to limited space inside the habitat. Confirmed media will receive additional details on how to participate.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA marked a key milestone Feb. 18 with installation of RS-25 engine No. E20001, the first new production engine to help power the SLS (Space Launch System) rocket on future Artemis missions to the Moon.
The engine, built by lead SLS engines contractor L3Harris (formerly Aerojet Rocketdyne), was installed on the Fred Haise Test Stand in preparation for acceptance testing next month. It represents the first of 24 new flight engines being built for missions, beginning with Artemis V.

During missions to the Moon, RS-25 engines fire for about 500 seconds and up to the 111% power level to help launch SLS, with the Orion spacecraft, into orbit.
The engine arrived at the test stand from the L3Harris Engine Assembly Facility on the engine transport trailer before being lifted onto the vertical engine installer (VEI) on the west side deck. After rolling the engine into the stand, the team used the VEI to raise and secure it in place.
The upcoming acceptance test follows two certification test series that helped verify the new engine production process and components meet all performance requirements. Four RS-25 engines help launch SLS, producing up to 2 million pounds of combined thrust.
All RS-25 engines for Artemis missions are tested and proven flightworthy at NASA Stennis prior to use. RS-25 tests are conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.

“We’re trying to tap into the community college talent pool to bring new students to the table for aeronautics,” said Steven Holz, who manages the USRC award process. “Innovation comes from everywhere, and people with different viewpoints, educational backgrounds, and experiences like those in our community colleges are also interested in aeronautics and looking to make a difference.”
Real World Research Awards
Through USRC, students interact with real-world aspects of the research ecosystem both in and out of the laboratory. They will manage their own research projects, utilize state-of-the-art technology, and work alongside accomplished aeronautical researchers. Students are expected to make unique contributions to NASA’s research priorities.
USRC provides more than just experience in technical research.
Each team of students selected receives a USRC grant from NASA – and is tasked with the additional challenge of raising funds from the public through student-led crowdfunding. The process helps students develop skills in entrepreneurship and public communication.
The new university teams and research topics are:
Cerritos Community College
“Project F.I.R.E. (Fire Intervention Retardant Expeller)” will explore how to mitigate wildfires by using environmentally friendly fire-retardant pellets dropped from drones. Cerritos Community College’s team includes lead Angel Ortega Barrera as well as Larisa Mayoral, Paola Mayoral Jimenez, Jenny Rodriguez, Logan Stahl, and Juan Villa, with faculty mentor Janet McLarty-Schroeder. This team also successfully participated with the same research topic in in NASA’s Gateway to Blue Skies competition, which aims to expand engagement between the NASA’s University Innovation project and universities, industry, and government partners.
Colorado School of Mines
The project “Design and Prototyping of a 9-phase Dual-Rotor Motor for Supersonic Electric Turbofan” will work on a scaled-down prototype for an electric turbofan for supersonic aircraft. The Colorado School of Mines team includes lead Mahzad Gholamian as well as Garret Reader, Mykola Mazur, and Mirali Seyedrezaei, with faculty mentor Omid Beik.
Complete details on USRC awardees and solicitations, such as what to include in a proposal and how to submit it, are available on the NASA Aeronautics Research Mission Directorate solicitation page.
