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.

Space is not the safest place to be. During spaceflight, both devices and humans risk exposure to high levels of radiation. Without sufficient protection, instruments would malfunction, and astronauts might face serious health risks. A team of researchers from Ghent University in Belgium are testing the potential of 3D-printed hydrogels – materials that can soak up large amounts of water – to serve as highly-effective radiation shields.

What’s Up for February? The Moon’s many engagements, what’s the right term for a planetary rendezvous, and the goddess of love draws near.
Moon & Planets
Starting with the Moon’s journey across the sky this month, you’ll find the slim crescent of Earth’s natural satellite cozied up to the planet Venus on the 1st. It then visits the Pleiades on the 5th, and hops over Jupiter on the 6th, looking increasingly fuller, before arriving right next to Mars on February 9th.
Sky chart showing Jupiter and Mars high overhead after nightfall in February 2025. Jupiter and Mars rule the sky on February nights. You’ll find them high overhead in the evening, together with the winter constellations of Orion, Taurus, and Gemini.
Appulses
Astronomers sometimes get picky about their terminology. For instance, the apparent close approaches of objects on the sky, like two planets, or the Moon and a planet, are commonly called “conjunctions,” and we often use that term in this video series.
However, most of the time, the technically correct term is an “appulse.” Conjunctions technically occur when two objects have the same right ascension, and they don’t have to appear close together in the sky. (Right ascension is a way of indicating where an object is along the sky from east to west, similar to how we measure longitude on Earth’s surface.)
Appulses are simply the times when two objects appear at their closest in the sky, regardless of whether they have to have the same “space coordinates.” The term comes from a Latin word meaning “brought near” or “driven toward.” And now that you know the distinction, you can choose to keep it casual or impress others with some next-level astronomy knowledge. Either way, it’s all about enjoying the view.
Venus Draws Near
February is a month for love, so what better time to spotlight Venus, which is associated with the Roman goddess of love? This month, Venus shines at its brightest for the year. It’ll remain dazzling through the start of March as it slowly descends from its late-January high point in the sky. By mid-March, it will disappear into the glare of sunset, only to reappear as a morning object in April.
Through a telescope, Venus becomes larger as it comes closer to Earth in its orbit. It also becomes a slimmer crescent. Nonetheless, this is when the planet is at its brightest in our skies. NASA/JPL-Caltech Now, you may have heard that Venus goes through phases, just like the Moon. You can see these phases with a modest telescope. But there’s a surprising twist: unlike the Moon, Venus isn’t at its brightest when it’s “full.” Instead, it shines most brilliantly in our skies when it’s a thinner crescent! It all comes down to distance. See, Venus only appears fuller when it’s on the far side of the Sun, and much farther from Earth. As it comes closer to us, its phase becomes a crescent, but the planet also looks much larger in the sky. Even as a crescent, the light from its closer position more than makes up for the smaller phase.
So, remember this Valentine’s proverb: “The goddess of love is at her most radiant when nearby!”

The award, signed by President Biden, is the highest honor the federal government can grant to a federal civilian employee.
NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy presented Cabana with the award during a ceremony at NASA Headquarters in Washington on Jan. 10. Cabana most recently served as NASA’s associate administrator, which is the agency’s highest ranking civil servant, from 2021 until he retired from the agency at the end of 2023.
“A true public servant, Bob has spent his entire career in service to his country. I can think of no one more deserving of this rare honor than Bob,” said Nelson. “From his time as a naval aviator to his role as associate administrator of NASA, Bob has dedicated his life to improving his country. I join with President Biden in thanking Bob for his dedication and commitment.”
The award recognized Cabana for his roles as a Marine aviator, test pilot, astronaut and becoming the first American to enter the International Space Station. He was further recognized for continuing to push for the bounds of the possible, launching the James Webb Space Telescope, the Artemis I mission and the Orion spacecraft which will send humans back to the Moon for the first time in decades.
As a NASA astronaut, Cabana flew in space four times, including twice as commander. His final space shuttle flight in 1998 was the first International Space Station assembly mission. Cabana also was the director of the agency’s Kennedy Space Center in Florida for more than a decade. There he led its transition from retirement of the space shuttle to a multi-user spaceport once again launching NASA astronauts to low Earth orbit, and for the first time, doing so with commercial partners.
As NASA associate administrator, Cabana led the agency’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters. He was the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion.
Cabana was selected as an astronaut candidate in June 1985 and completed training in July 1986. He logged 38 days in space during four shuttle missions. Cabana was a pilot aboard space shuttle Discovery on both the STS-41 mission in October 1990 that deployed the Ulysses spacecraft and the STS-53 mission in December 1992. He was the mission commander aboard space shuttle Columbia for the STS-65 mission in July 1994 that conducted experiments as part of the second International Microgravity Laboratory mission. He commanded space shuttle Endeavour for the STS-88 mission in December 1998.
Cabana was appointed a member of the Federal Senior Executive Service in 2000 and served in numerous senior management positions at NASA’s Johnson Space Center in Houston, ultimately becoming deputy director. He was named director of NASA’s Stennis Space Center in Mississippi in October 2007 and a year later was selected as NASA Kennedy director.
Born in Minneapolis, Cabana graduated from the U.S. Naval Academy in 1971 with a bachelor’s degree in mathematics. He became a naval aviator and graduated with distinction from the U.S. Naval Test Pilot School in 1981. In his career, Cabana logged over 7,000 hours in more than 50 different kinds of aircraft. He retired as a colonel from the U.S. Marine Corps in September 2000.
In addition to receiving the President’s Award for Distinguished Federal Service, Cabana’s accomplishments have been recognized with induction into the Astronaut Hall of Fame and being named an Associate Fellow in the American Institute of Aeronautics and Astronautics and a Fellow in the Society of Experimental Test Pilots. He has received numerous personal awards and decorations, including the Distinguished Flying Cross and the Presidential Distinguished Rank Award. He also is a recipient of the Rotary National Award for Space Achievement’s National Space Trophy.
