Member of NASA's SpaceX Crew-13 Mission are pictured during training at SpaceX headquarters in Hawthorne, California. Four crew members from three space agencies will launch no earlier than mid-September 2026 to the International Space Station for a long-duration science expedition.

NASA astronauts Jessica Watkins and Luke Delaney will serve as spacecraft commander and pilot, respectively. They will be joined by the Canadian Space Agency (CSA) astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov of Russia that will serve as mission specialists. After arriving at the orbiting laboratory, Crew-13 will become members of the space station’s Expedition 75.

This flight is the 13th crew rotation with SpaceX to the space station as part of NASA’s Commercial Crew Program (CCP). NASA is advancing the launch date of Crew-13 from November to help increase the frequency of U.S. crew rotation missions to the space station. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future exploration missions to the Moon and Mars, and benefit people on Earth.

This will be the second flight to the space station for Watkins. She was selected as a NASA astronaut in 2017. Watkins grew up in Lafayette, Colorado, and earned an undergraduate degree in geological and environmental sciences from Stanford University, as well as a doctorate in geology from the University of California, Los Angeles. As a geologist, she studied the Martian surface and was a member of the Curiosity rover science team at NASA’s Jet Propulsion Laboratory in Southern California. Watkins first launched to the space station as a crew member aboard NASA’s SpaceX Crew-4 mission, spending a total of 170 days in space across Expeditions 67/68 in 2022. She will be the first NASA astronaut to launch aboard a SpaceX Dragon spacecraft twice.

Selected as a NASA astronaut in 2021, Delaney earned a bachelor’s degree in mechanical engineering at the University of North Florida and a master’s degree in aerospace engineering at the Naval Postgraduate School. The Florida native is a distinguished naval aviator. As a test pilot, Delaney evaluated developmental aircraft systems and served as a test pilot instructor. He also worked as a research pilot at NASA’s Langley Research Center in Hampton, Virginia, where he supported airborne science missions. This is the first spaceflight for Delaney.

The Crew-13 mission also is the first spaceflight for Kutryk. Prior to his selection as a CSA astronaut in 2017, he served as a CF-18 pilot. A native of Fort Saskatchewan, Alberta, Kutryk also worked as an experimental and operational test pilot at the Aerospace Engineering Test Establishment in Cold Lake, Alberta. Kutryk received a bachelor’s degree in mechanical engineering from the Royal Military College of Canada in Kingston, Ontario, and he is a distinguished graduate of the United States Air Force Test Pilot school in Edwards, California. He has master’s degrees in space studies, flight test engineering, and defense studies.

Crew-13 will be Teteryatnikov’s first trip to the orbiting laboratory. He graduated from the Naval Academy, St. Petersburg, Russia, in 2011 as an engineer specializing in ship power plant operations. Before his selection as a test cosmonaut, Teteryatnikov served in various naval engineering roles, including undersea vessels and specialized engine room operations. He was selected for the Gagarin Research and Test Cosmonaut Training Center Cosmonaut Corps in 2021 and has served as a test cosmonaut since 2023.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.

Mysterious Distant "Little Red Dots" Detected | NASA Chandra & Webb Telescopes

Mysterious Distant "Little Red Dots" Detected | NASA Chandra & Webb Telescopes

A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. Shortly after NASA’s James Webb Space Telescope started its science observations, reports of a new class of mysterious objects emerged. Astronomers found small, red objects that are about 12 billion light-years from Earth or farther that became known as “little red dots,” or LRDs.

Many scientists think LRDs are supermassive black holes embedded in clouds of dense gas that mask typical light signatures—including x-rays—that astronomers usually use to identify them. This would make them distinct from typical growing supermassive black holes that are not embedded in dense gas, allowing bright ultraviolet light and x-rays from material orbiting the black holes to escape.

Because of this and their potential similarities to stellar atmospheres, astronomers have called this the “black hole star” scenario for LRDs.

This new object discovered by Chandra is exciting because it is the first LRD that is known to give off x-rays. Because of that, the astronomers that found this object nicknamed it the “x-ray dot.”

Located about 11.8 billion light-years from Earth, the x-ray dot may provide a crucial bridge between black hole stars and typical growing supermassive black holes. It exhibits most of the features of an LRD, including being small, red, and located at a vast distance, but it glows in x-ray light, unlike other LRDs.

Finding a little red dot that does gives researchers important new insight into what could power them. The researchers suggest that the x-ray dot represents a transition phase from an LRD to a typical growing supermassive black hole. As the black hole star consumes its surrounding gas, patchy holes in the clouds of gas appear. This allows x-rays from material falling onto the black hole to poke through that are observed by Chandra. Eventually all the gas is consumed, and the black hole star ceases to exist.

The astronomers were only able to find this x-ray emitting little red dot by comparing new surveys from James Webb with deep observations from Chandra. They will continue to combine the data from these two powerful observatories to look for more examples of this behavior to hopefully help further unravel the mysteries surrounding little red dots.

Astronaut Christina Koch’s Memorable International Space Station Moments: Part 4

Astronaut Christina Koch’s Memorable International Space Station Moments: Part 4

During the longest-ever single spaceflight by a female astronaut, NASA astronaut Christina Koch also completed six spacewalks. Here, Koch recalls the biggest surprise of the mission and the most memorable item she received on a cargo flight.  

Six years before her Artemis II Moon Mission, NASA astronaut, scientist, mission specialist, flight engineer, and spacewalker Christina Koch spent almost a year in space on International Space Station Expeditions 59-61 (March 2019-February 2020), before coming home. 

When Koch returned to Earth after her long-duration human spaceflight mission, she had lived in space for 328 days, setting the record for the longest single spaceflight by a woman. During this time, Koch spent many of her hours on science activities aboard the International Space Station and wore many hats—farmer, biologist, physicist, engineer, test subject and many more. 

Christina also participated in the first all-female spacewalk with fellow NASA astronaut Jessica Meir, currently serving aboard the International Space Station on Expedition 74.

NASA's Jet Propulsion Laboratory Tests Next-Generation Electric Thruster for Mars

NASA's Jet Propulsion Laboratory Tests Next-Generation Electric Thruster for Mars


A prototype of a powerful new lithium-fed electric thruster that could one day help send humans to Mars was successfully tested at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

Known as a magnetoplasmadynamic (MPD) thruster, the thruster runs on lithium metal vapor and is capable of reaching power levels far beyond today’s electric propulsion systems. 

During a recent test at JPL’s Electric Propulsion Lab, the thruster achieved power levels of up to 120 kilowatts, more than 25 times that of the highest-power electric thrusters on any current NASA spacecraft.

​​The JPL team has been developing the thruster for the past 2½ years under NASA’s Space Nuclear Propulsion project, based at the agency’s Marshall Space Flight Center in Huntsville, Alabama. The test took place on Feb. 24, 2026, and its results will assist upcoming tests.

While much more development is needed before the technology can be used in space, this milestone marks an important step toward nuclear electric propulsion systems that could reduce travel time to Mars and lower risk for astronauts on long-duration missions.

Two solid rocket boosters from NASA’s Space Launch System (SLS) rocket separate from the core stage and Orion spacecraft

NASA’s Space Launch System (SLS) rocket carrying the Orion spacecraft with NASA astronauts Reid Wiseman, commander; Victor Glover, pilot; Christina Koch, mission specialist; and Canadian Space Agency (CSA) astronaut Jeremy Hansen, mission specialist onboard launched on the Artemis II Mission, Wednesday, April 1, 2026, from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. 

During their nearly 10-day mission, the crew completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth and 4,067 miles above the lunar surface at their closest approach. 

Artemis II splashed down at 8:07 p.m. April 10 in the Pacific Ocean off the coast of San Diego. Following splashdown and recovery, the four crew members underwent post-mission medical evaluations before returning to shore and boarding an aircraft bound for Houston. Upon arrival, the crew was welcomed by and reunited with their families, friends, and agency workforce. The crew then began their postflight reconditioning, medical and human performance evaluations, and lunar science debriefs.

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

Spiral Galaxy NGC 4394 in Coma Berenices | Hubble Space Telescope

Spiral Galaxy NGC 4394 in Coma Berenices | Hubble Space Telescope

Discovered in 1784 by the German–British astronomer William Herschel, NGC 4394 is a barred spiral galaxy situated about 55 million light-years from Earth. The galaxy lies in the constellation of Coma Berenices (Berenice's Hair), and is considered to be a member of the Virgo Cluster.

NGC 4394 is the archetypal barred spiral galaxy with bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. At the center of NGC 4394 lies a region of ionized gas known as a LINER. LINERs are active regions that display a characteristic set of emission lines in their spectra—mostly weakly ionized atoms of oxygen, nitrogen, and sulphur.

Although LINER galaxies are relatively common, it is still unclear where the energy comes from to ionize the gas. In most cases it is thought to be the influence of a black hole at the center of the galaxy, but it could also be the result of a high level of star formation. In the case of NGC 4394, it is likely that gravitational interaction with a nearby neighbor has caused gas to flow into the galaxy’s central region, providing a new reservoir of material to fuel the black hole or to make new stars.

ViaSat-3 F3 communications satellite

SpaceX is now targeting Wednesday, April 29, 2026, for Falcon Heavy’s launch of the ViaSat-3 F3 mission from Florida. The 85-minute window opens at 10:13 a.m. Eastern Time (ET) →Watch here: http://spacex.com/launches/viasat3f3

A SpaceX Falcon Heavy rocket can be seen at Launch Complex 39A, NASA's Kennedy Space Center in Merritt Island, Florida, ahead of the upcoming Viasat-3 F3 Mission. A Falcon Heavy rocket reduces time to orbit by delivering the satellite to a more favorable transfer orbit where this satellite’s electric propulsion will take over to place ViaSat-3 F3 into a geostationary orbit. Following launch, the ViaSat-3 F3 satellite will spend several months traveling to geostationary orbit before arriving at its reserved orbital slot. It will go through rigorous in-orbit testing of both the bus and payload before entering service, expected to occur by late summer 2026. ViaSat-3 satellites are each designed to provide regional coverage with ViaSat-3 F3 expected to cover the Asia-Pacific (APAC) region.

One of the side boosters on this mission previously supported SDA-0A, SARah-2, Transporter-11, and 18 Starlink missions, and the second previously supported launch of the GOES-U mission. Following stage separation, Falcon Heavy’s two side boosters will land on SpaceX’s Landing Zones 2 and 40 (LZ-2 and LZ-40) at Cape Canaveral in Florida.

Comet C/2025 R3 (PANSTARRS) Views | Solar and Heliospheric Observatory (SOHO)

Comet C/2025 R3 (PANSTARRS) Views | Solar and Heliospheric Observatory (SOHO)

The Solar and Heliospheric Observatory (SOHO) has captured views of Comet C/2025 R3 PANSTARRS in-between the Sun and Earth. In the SOHO satellite's LASCO C3 imagery, Comet C/2025 R3 PanSTARRS emerges from the right edge of the frame.

C/2025 R3 (PanSTARRS) is a hyperbolic Oort cloud comet. It passed perihelion (closest approach to the Sun) on April 19, 2026, when it was 0.499 AU (75 million km) from the Sun. The comet was discovered by PanSTARRS in images obtained on September 8, 2025.

SOHO is a European Space Agency (ESA) spacecraft that has discovered over 5,000 comets. SOHO was launched in 1995 from NASA's Kennedy Space Center. It began science operations in May 1996. It is a joint project between the European Space Agency (ESA) and NASA. The Large Angle and Spectrometric COronagraph (LASCO) instrument is one of 11 instruments. The LASCO instrument is a set of three coronagraphs that image the solar corona from 1.1 to 32 solar radii. It is convenient to measure distances in terms of solar radii. One solar radius is about 700,000 km, 420,000 miles or 16 arc minutes. A coronagraph is a telescope that is designed to block light coming from the solar disk, in order to see the extremely faint emissions from the region around the sun, called the corona.

The Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) located at Haleakala Observatory, Hawaii, USA, consists of astronomical cameras, telescopes and a computing facility that is surveying the sky for moving or variable objects on a continual basis, and also producing accurate astrometry and photometry of already-detected objects. The Pan-STARRS Project is a collaboration between the University of Hawaiʻi Institute for Astronomy, MIT Lincoln Laboratory, Maui High Performance Computing Center and Science Applications International Corporation (SAIC). The NASA Near Earth Object Observation Program is the main funder for the operation of the Pan-STARRS telescopes.

A United States National Oceanic and Atmospheric Administration (NOAA) satellite caught a celestial visitor! As Comet C/2025 R3 (PanSTARRS) passed by Earth during April 24–25, 2026, the Compact Coronagraph (CCOR1), a solar telescope, on NOAA's GOES-19 weather satellite tracked its path. The comet was discovered last September by the Haleakalā Observatory in Hawaii.

C/2025 R3 (PanSTARRS) is a hyperbolic Oort cloud comet. It passed perihelion (closest approach to the Sun) on April 19, 2026, when it was 0.499 AU (75 million km) from the Sun. The comet was discovered by PanSTARRS in images obtained on September 8, 2025.

A coronagraph is a type of telescope designed to block the light from a star or the solar disk, allowing astronomers to observe the faint emissions from the surrounding region, such as the solar corona. It was invented in 1930 by French astronomer Bernard Lyot and is primarily used to study solar phenomena like prominences and the corona itself. By using a disk to obscure the bright light, coronagraphs enable the observation of nearby celestial objects that would otherwise be hidden.

Billions of Years of Martian History—NASA’s Perseverance & Curiosity Rovers | JPL

Billions of Years of Martian HistoryNASA’s Perseverance & Curiosity Rovers | JPL

NASA has two rovers on Mars—but they are exploring distinct eras of the planet’s past. Separated by 2,300 miles, the two rovers are uncovering clues from moments in Martian history. Perseverance is on the rim of Jezero Crater, where it is studying examples of the oldest Martian terrain explored while searching for signs of ancient microbial life. Meanwhile, Curiosity is climbing Mount Sharp inside Gale Crater, where layers of rock reveal how Mars’ climate changed as water dried up from its surface.

Together, the missions are helping scientists reconstruct how Mars formed, when and where water existed, and the planet’s history of having the right conditions to support life. Their discoveries are offering a clearer picture of how Mars became the dry and dusty world we know today.

The Apollo 17 astronauts landed in the Taurus Littrow Valley over fifty-three years ago. One of their key science goals was to collect impact melt from the Serenitatis basin rim so an age date for this important basin could be established. Before the samples were returned most lunar geologists believed this basin to be relatively old amongst all lunar basins. When the age dates came in from the Apollo 17 highland impact melt samples it appeared that the Serenitatis basin was younger than previously thought (3.86 billion years), nearly the same age as the mighty Imbrium basin (young in terms of lunar basins). Jack Schmitt and Gene Cernan sampled rocks from South and North Massifs and the Sculptured Hills, all three thought to be formed as part of the Serenitatis basin impact event.

The wisdom at the time was that the old relative age assignment of the Serenitatis basin derived from remotely sensed image data must be wrong. Perhaps the confidence of that interpretation was undermined by the relatively poor resolution of the then-existing orbital image data for much of the eastern portion of the nearside of the Moon.

The new Wide Angle Camera (WAC) global mosaic and Narrow Angle Camera (NAC) high resolution views are allowing scientists to reevaluate many previously held ideas with much clearer data. A new look at the area around the Serenitatis basin using the geologic rule of superposition (Spudis and coworkers, 2011) with the Lunar Reconnaissance Orbiter Camera (LROC) images resulted in a confident determination that the Sculptured Hills are actually far flung ejecta from the Imbrium basin, and not Serenitatis basin material. Littrow crater in turn was formed on the rim of Serenitatis basin. Thus the Sculptured Hills formed after the Serenitatis basin formed, likely as ejecta from the Imbrium basin impact event.

What does this new finding mean? 
First, if the Sculptured Hills are really Imbrium ejecta it is possible (or even likely) that the Apollo 17 impact melts do not represent the formation age of the Serenitatis basin, but rather that of the Imbrium basin. If so, the evidence that there was a late cataclysm (a big short spike in impact events) just got a lot weaker. On the other hand, if those impact melts do indeed come form the Serenitatis formation event, the fact that Serenitatis is relatively old amongst lunar basins means the late cataclysm was even more compressed than previously thought. In fact, it would suggest that 13-25 of the larger basins all formed within a short period of 50 million years (short in geologic time). Either way, the new determination of the relative age of the Serenitatis basin results in a radical new evaluation of the sequence of events early in lunar history.

Reflecting back on the last human landing on the Moon, and the results of the Lunar Reconnaissance Orbiter (LRO) and other recent missions, we can see that the Apollo landings were a fantastic start to our exploration of the Moon. Many questions were answered from data and samples collected during the Apollo era. Since then, many new discoveries about the Moon have arrived, and more key science questions have appeared. The work begun by astronauts Schmitt and Cernan is now being extended by LRO in preparation for the next generation of lunar explorers. With the LROC data we can now map out the best places to search for outcrops of Serenitatis rock (especially impact melt) and obtain a confident age date for this key basin that in turn places many of the other large basins in their proper absolute age.

LRO has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites.

LRO has been studying the Moon from up close since 2009, making it the longest-lived lunar orbiting mission ever. The orbiter has mapped the Moon’s surface and measured its temperature, composition, and radiation environment in unprecedented detail. Data from LRO enables NASA, and our international and commercial partners, to select locations on the lunar surface where spacecraft and astronauts can safely land. The orbiter is also helping NASA identify areas near the Moon’s South Pole with crucial resources like water and extended sunlight that provides power for equipment and supports exploration activities.
