Skywatching Highlights
All Month – Planet Visibility:
Mercury: Visible for a few days in the second half of April, extremely low in the east before sunrise. Venus: Rising low in the east in the hour before dawn. Mars: Bright and easy to view after dark all month. Setting a couple of hours after midnight. Jupiter: Bright and easy to spot in the west after dark, setting a couple of hours after sunset. Saturn: Visible low in the east below Venus, before dawn in the last two weeks of April. Daily Highlights:
April 1 & 30 – Jupiter & Crescent Moon: Find the charming pair in the west as the sky darkens, setting about 3 hours after sunset.
April 4 & 5 – Mars & Moon: The Moon, around its first quarter phase, appears near Mars in the sky for two nights.
April 24-25 – Grouping of the Moon & Three Planets: Find Venus, Saturn, and the crescent moon gathered low in the east as dawn warms the morning sky. Mercury is also visible below them for those with a clear view to the horizon.
All month – Venus: Earth’s hothouse twin planet has made the shift from an evening object to a morning sight. You’ll notice it rising low in the east before dawn, looking a little higher each morning through the month.
All month – Mars: Looking bright and reddish in color, Mars is visible high overhead after dark all month. At the start of the month it lies along a line with bright stars Procyon and Pollux, but you’ll notice it moves noticeably over the course of April (~12 degrees or the width of your outstretched fist at arm’s length).
Transcript
What’s Up for April? Planets at dusk and dawn, April showers, and observing a distant city of stars.
Sky chart showing Jupiter and the crescent Moon on April 1. A similar scene repeats on April 30, but with the Moon appearing above Jupiter. NASA/JPL-Caltech First up, in the evening sky, we begin and end the month with Jupiter and the crescent Moon shining brightly together in the western sky as sunset fades. On both April 1st and 30th, you can find the charming pair about half an hour after sunset, setting about 3 hours later.
Mars is high overhead in the south on April evenings. At the start of the month, it’s directly in between bright stars Procyon and Pollux, but it moves noticeably during the month. You’ll find the first-quarter moon right next to Mars on April 4th and 5th.
Moving to the morning sky, Venus has now made the switch from an evening object to a morning one. You may start to notice it rising low in the east before dawn, looking a little higher each morning through the month.
Sky chart showing the eastern sky 45 minutes before sunrise on April 24, with Venus, Saturn and the crescent Moon forming a grouping low in the sky. Mercury might also be visible for those with a completely clear view to the horizon. NASA/JPL-Caltech Around April 24th and 25th, you’ll find Venus, Saturn, and the crescent moon gathered low in the east as dawn warms up the morning sky. Those with a clear view to the horizon might also pick out Mercury looking bright, but very low in the sky.
April brings shooting stars as Earth passes through one the streams of comet dust that create our annual meteor showers. The Lyrids are a modest meteor shower that peaks overnight on April 21st and into the morning of the 22nd. You can expect up to 15 meteors per hour near the peak under dark skies.
The Lyrids are best observed from the Northern Hemisphere, but can be seen from south of the equator as well. View them after about 10:30pm local time until dawn, with the best viewing around 5 a.m. The waning crescent moon will rise around 3:30am, but at only 27% full, it shouldn’t interfere too much with your meteor watching. For the best experience, face roughly toward the east, lie down in a safe, dark place away from bright lights, and look straight overhead. Meteors can appear anywhere in the sky, and some Lyrids can leave bright trails that last for a few seconds after they’ve passed.
NASA studies meteors from the ground, in the air, and from orbit to forecast meteor activity and protect spacecraft, and to understand the composition of comets and asteroids throughout our solar system.
Sky chart facing east around 9pm in April 2025 showing the location of globular cluster M3. The chart depicts the cluster’s position relative to the Big Dipper and bright stars Arcturus and Cor Caroli. The Big Dipper star Megrez serves as an indicator for the brightness of Cor Caroli. For easy visibility, M3 is depicted brighter and larger than its actual appearance. NASA/JPL-Caltech April offers a chance to observe a truly distant wonder – a globular cluster known as “M3.” It’s a vast collection of stars that lies 34,000 light-years from Earth in our galaxy’s outer reaches. Astronomer Charles Messier discovered this object in 1764, while searching for new comets. Realizing it wasn’t one, he added it to his list of interesting objects that were not comets, which today we know as Messier’s catalog.
Through binoculars, Messier 3, or M3, appears as a small, fuzzy, star-like patch of light. With a small telescope, you’ll see a more defined glow with a slightly grainy texture. And with telescopes 8 inches or larger, the cluster begins to resolve into hundreds of individual stars.
Now, globular clusters contain some of the oldest stars in the universe, often over 10 billion years old. Unlike open clusters like the Pleiades, which sit within the Milky Way’s spiral arms, globular clusters are found in the galaxy’s halo, orbiting far above and below the Milky Way’s disk. Our galaxy has around 150 confirmed globular clusters. M3 itself is probably 11 to 13 billion years old and contains around half a million stars. And it’s relatively easy to spot in April under dark skies with binoculars or a small telescope.
Finding M3 starts with the Big Dipper. Facing east, use the Dipper’s handle to “arc to Arcturus,” the fourth-brightest star in the night sky. From there, look higher in the sky to find the star Cor Caroli located here to the west of the Dipper’s handle. It’s about as bright as this star in the Dipper’s cup. M3 is located roughly a third of the way from Arcturus to Cor Caroli. With binoculars or a finder scope, sweep within this area until you spot a faint, round glow.
M3 is an excellent target for beginners and seasoned observers alike. Whether using binoculars or a telescope, you’ll be rewarded with a view of one of the oldest objects in our galaxy.

The XS-11 and the Transition Away from Mandatory Jet Pilot Training for NASA Astronauts
By Jennifer Ross-Nazzal
Flying in space has been associated with pilots ever since 1959, when NASA announced its first class of astronauts, known as the Mercury 7. Part of being a professional astronaut meant you were a certified jet pilot. Even the scientist-astronauts, so named to differentiate them from the astronauts assigned to the Mercury and Gemini missions, selected in 1965 and in 1967, received pilot training. Until NASA better understood the impact of weightlessness on the human body, Robert R. Gilruth, head of the Manned Spacecraft Center (MSC) in Houston, believed all astronauts should meet this qualification. But when five scientist-astronauts from the 1967 class had a rocky transition, leading them to resign—due to their disinterest in flying at the cost of their scientific training and no spaceflight opportunities—it eventually led NASA to rethink their idea of having all astronauts become jet pilots.

By Lois Rosson
In June 2011, the Stratospheric Observatory for Infrared Astronomy (SOFIA) chased down Pluto’s occultation of a far-away star. … SOFIA’s 2011 observation of Pluto followed up on a historic 1988 observation made by the airborne Kuiper Airborne Observatory (KAO) that proved that Pluto had an atmosphere at all. The technical versatility of both flights, conducted from aircraft hurtling stabilized telescopes through the air, speaks to the legacy of airborne astronomical observation at NASA. But how did this idiosyncratic format emerge in the first place? Airborne astronomy, in which astronomical observations are made from a moving aircraft, was attempted almost as soon as airplanes themselves were developed. Continue Reading
NASA’s Tortuous Effort to Consolidate its Aircraft
By Robert Arrighi
Thirty years ago, on January 6, 1995, NASA Administrator Dan Goldin announced, “We’ve started a revolution at NASA. It’s real. We have a road map for change. We’ve already begun.” Thus began one of the agency’s most daunting endeavors, a top-to-bottom reassessment of NASA’s processes, programmatic assignments, and staffing levels. One of the most controversial aspects of this effort was the proposal to transfer nearly all of the agency’s research aircraft to Dryden Flight Research Center (today known as Armstrong).

By Brad Massey
Skylab astronaut Edward G. Gibson looked down at Earth often during his 84 days on NASA’s first space station. From his orbital vantage point, Gibson took in the breathtaking views of our planet’s diverse landscapes. He also noted the interesting behavior of the planet’s most powerful electrical force: lightning. … Gibson’s words were of great interest to the lightning researchers affiliated with NASA’s Severe Storms and Local Research Program and others who believed observing Earth’s lightning from low Earth orbit generated valuable data that meteorologists could use to better forecast dangerous storm characteristics and behavior. With these motivations in mind, researchers created new Earth- and space-based experiments from the mid-1960s to the first Space Shuttle missions in the early 1980s that observed lightning on a regional level.

By James Anderson
One hundred ten years ago this month, NASA’s predecessor organization, the National Advisory Committee for Aeronautics (NACA), was founded. The date of the anniversary marks the passage of a rider to a naval appropriations bill that established the NACA for the modest sum of $5,000 annually. Telling the story of the NACA’s founding in this manner—using March 3, 1915, as the moment in time to represent the NACA’s beginning—is true, but it overlooks two crucial aspects of the founding. The founding was both a culmination and a turning point for science and aeronautics in the United States. Continue Reading

From left are Mission Specialist Kimiya Yui from JAXA (Japan Aerospace Exploration Agency), Commander NASA astronaut Zena Cardman, Mission Specialist Oleg Platonov of Roscosmos, and Pilot NASA astronaut Mike Fincke.Credit: NASA As part of NASA’s SpaceX Crew-11 mission, four crew members from three space agencies will launch in the coming months to the International Space Station for a long-duration science expedition aboard the orbiting laboratory.
NASA astronauts Commander Zena Cardman and Pilot Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Mission Specialist Kimiya Yui, and Roscosmos cosmonaut Mission Specialist Oleg Platonov will join crew members aboard the space station no earlier than July 2025.
The flight is the 11th crew rotation with SpaceX to the station as part of NASA’s Commercial Crew Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future missions to the Moon, as well as benefit people on Earth.
Cardman previously was assigned to NASA’s SpaceX Crew-9 mission, and Fincke previously was assigned to NASA’s Boeing Starliner-1 mission. NASA decided to reassign the astronauts to Crew-11 in overall support of planned activities aboard the International Space Station. Cardman carries her experience training as a commander on Dragon spacecraft, and Fincke brings long-duration spaceflight experience to this crew complement.
Selected as a NASA astronaut in 2017, Cardman will conduct her first spaceflight. The Williamsburg, Virginia, native holds a bachelor’s degree in Biology and a master’s in Marine Sciences from the University of North Carolina at Chapel Hill. At the time of selection, she had begun pursuing a doctorate in Geosciences. Cardman’s research in geobiology and geochemical cycling focused on subsurface environments, from caves to deep sea sediments. Since completing initial training, Cardman has supported real-time station operations and lunar surface exploration planning.
This will be Fincke’s fourth trip to the space station, having logged 382 days in space and nine spacewalks during Expedition 9 in 2004, Expedition 18 in 2008, and STS-134 in 2011, the final flight of space shuttle Endeavour. Throughout the past decade, Fincke has applied his expertise to NASA’s Commercial Crew Program, advancing the development and testing of the SpaceX Dragon and Boeing Starliner toward operational certification. The Emsworth, Pennsylvania, native is a distinguished graduate of the United States Air Force Test Pilot School and holds bachelors’ degrees from the Massachusetts Institute of Technology, Cambridge, in both Aeronautics and Astronautics, as well as Earth, Atmospheric and Planetary Sciences. He also has a master’s degree in Aeronautics and Astronautics from Stanford University in California. Fincke is a retired U.S. Air Force colonel with more than 2,000 flight hours in more than 30 different aircraft.
With 142 days in space, this will be Yui’s second trip to the space station. After his selection as a JAXA astronaut in 2009, Yui flew as a flight engineer for Expedition 44/45 and became the first Japanese astronaut to capture JAXA’s H-II Transfer Vehicle. In addition to constructing a new experimental environment aboard Kibo, he conducted a total of 21 experiments for JAXA. In November 2016, Yui was assigned as chief of the JAXA Astronaut Group. He graduated from the School of Science and Engineering at the National Defense Academy of Japan in 1992. He later joined the Air Self-Defense Force at the Japan Defense Agency (currently Ministry of Defense). In 2008, Yui joined the Air Staff Office at the Ministry of Defense as a lieutenant colonel.
The Crew-11 mission will be Platonov’s first spaceflight. Before his selection as a cosmonaut in 2018, Platonov earned a degree in Engineering from Krasnodar Air Force Academy in Aircraft Operations and Air Traffic Management. He also earned a bachelor’s degree in State and Municipal Management in 2016 from the Far Eastern Federal University in Vladivostok, Russia. Assigned as a test cosmonaut in 2021, he has experience in piloting aircraft, zero gravity training, scuba diving, and wilderness survival.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.
