This artist's concept, updated as of June 2020, depicts NASA's Psyche spacecraft. Set to launch in August 2022, the Psyche mission will explore a metal-rich asteroid of the same name that lies in the main asteroid belt between Mars and Jupiter. The spacecraft will arrive in early 2026 and orbit the asteroid for nearly two years to investigate its composition. Scientists think that Psyche, unlike most other asteroids that are rocky or icy bodies, is made up of mostly iron and nickel — similar to the Earth's core. The Psyche team will use a magnetometer to measure the asteroid's magnetic field. A multispectral imager will capture images of the surface, as well as data about the Psyche's composition and topography. Spectrometers will analyze the neutrons and gamma rays coming from the surface to reveal the elements that make up the asteroid itself. https://photojournal.jpl.nasa.gov/catalog/PIA23875

This artist's concept shows a hypothetical planet covered in water around the binary star system of Kepler-35A and B. In a 2017 study in the journal Nature Communications, researchers investigating the climates of exoplanets determined that this hypothetical planet could be habitable, depending on its distance from the two stars. On the far edge of the habitable zone, the hypothetical water-covered planet would have a lot of variation in its surface temperatures. But closer to the stars, near the inner edge of the habitable zone, the global average surface temperatures on the same planet would stay almost constant. https://photojournal.jpl.nasa.gov/catalog/PIA21470

This artist's concept depicts the 140-mile-wide (226-kilometer-wide) asteroid Psyche, which lies in the main asteroid belt between Mars and Jupiter. Psyche is the focal point of NASA's mission of the same name. The Psyche spacecraft is set to launch in August 2022 and arrive at the asteroid in 2026, where it will orbit for 21 months and investigate its composition. Scientists think that Psyche, unlike most other asteroids that are rocky or icy bodies, is made up of mostly iron and nickel — similar to the Earth's core. Exploring the asteroid could give valuable insight into how our own planet and others formed. The Psyche team will use a magnetometer to measure the asteroid's magnetic field. A multispectral imager will capture images of the surface, as well as data about the Psyche's composition and topography.

Perseverance will arrive at Mars' Jezero Crater with Ingenuity attached to its belly. https://photojournal.jpl.nasa.gov/catalog/PIA23962

An artist's concept of the Magellan spacecraft making a radar map of Venus. Magellan mapped 98 percent of Venus' surface at a resolution of 100 to 150 meters (about the length of a football or soccer field), using synthetic aperture radar, a technique that simulates the use of a much larger radar antenna. It found that 85 percent of the surface is covered with volcanic flows and showed evidence of tectonic movement, turbulent surface winds, lava channels and pancake-shaped domes. Magellan also produced high-resolution gravity data for 95 percent of the planet and tested a new maneuvering technique called aerobraking, using atmospheric drag to adjust its orbit. The spacecraft was commanded to plunge into Venus' atmosphere in 1994 as part of a final experiment to gather atmospheric data. http://photojournal.jpl.nasa.gov/catalog/PIA18175

This artist's concept shows a black hole with an accretion disk -- a flat structure of material orbiting the black hole -- and a jet of hot gas, called plasma. Using NASA's NuSTAR space telescope and a fast camera called ULTRACAM on the William Herschel Observatory in La Palma, Spain, scientists have been able to measure the distance that particles in jets travel before they "turn on" and become bright sources of light. This distance is called the "acceleration zone." https://photojournal.jpl.nasa.gov/catalog/PIA22085

This artist's concept illustrates one possible answer to the puzzle of the "giant galactic blobs." These blobs (red), first identified about five years ago, are mammoth clouds of intensely glowing material that surround distant galaxies (white). Astronomers using visible-light telescopes can see the glow of the blobs, but they didn't know what provides the energy to light them up. NASA's Spitzer Space Telescope set its infrared eyes on one well-known blob located 11 billion light-years away, and discovered three tremendously bright galaxies, each shining with the light of more than one trillion Suns, headed toward each other. Spitzer also observed three other blobs in the same galactic neighborhood and found equally bright galaxies within them. One of these blobs is also known to contain galaxies merging together. The findings suggest that galactic mergers might be the mysterious source of blobs. If so, then one explanation for how mergers produce such large clouds of material is that they trigger intense bursts of star formation. This star formation would lead to exploding massive stars, or supernovae, which would then shoot gases outward in a phenomenon known as superwinds. Blobs produced in this fashion are illustrated in this artist's concept. http://photojournal.jpl.nasa.gov/catalog/PIA07221

The data was recorded during close flybys of the moon in December 2023 and February 2024. The mountain, which the Juno science team has nicknamed "Steeple Mountain," is between 3 and 4.3 miles (5 and 7 kilometers) in height. One side of Steeple Mountain is in shade in the animation because only one side of the mountain was illuminated when imaged by JunoCam.

This illustration shows a concept for a set of future robots working together to ferry back samples from the surface of Mars collected by NASA's Mars Perseverance rover. NASA and the European Space Agency (ESA) are solidifying concepts for a Mars sample return mission that would seek to take the samples of Martian rocks and other materials being collected and stored in sealed tubes by NASA's Mars Perseverance rover and return the sealed tubes to Earth. According to the current concept, NASA would deliver a Mars lander in the vicinity of Jezero Crater, where Perseverance (left) will have collected and cached samples. The Sample Retrieval Lander (right) would carry a NASA rocket (the Mars Ascent Vehicle), along with ESA's Sample Fetch Rover (center) that is roughly the size of the Opportunity Mars rover. The fetch rover would gather the cached samples and carry them back to the lander for transfer to the ascent vehicle; additional samples could also be delivered directly by Perseverance. The ascent vehicle would then launch a special container holding the samples into Mars orbit. ESA would put a spacecraft in orbit around Mars before the ascent vehicle launches. This spacecraft would rendezvous with and capture the orbiting samples before returning them to Earth. NASA would provide the capture and containment payload module for the orbiter. https://photojournal.jpl.nasa.gov/catalog/PIA24870

The 124-mile-long (200-kilometer-long) lake is filled with magma, rimmed with hot lava, and dotted with islands. Loki provided a spectacular reflection when imaged by JunoCam during flybys of the moon in December 2023 and February 2024, suggesting it and other parts of Io's surface are as smooth as glass. The large island in Loki Patera does not have a name. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA26293

This artist's concept shows what the weather might look like on cool star-like bodies known as brown dwarfs. These giant balls of gas start out life like stars, but lack the mass to sustain nuclear fusion at their cores, and instead, fade and cool with time. Observations from NASA's Spitzer Space Telescope suggest that most brown dwarfs are roiling with one or more planet-size storms akin to Jupiter's "Great Red Spot." https://photojournal.jpl.nasa.gov/catalog/PIA21475

This artist's concept depicts "heartbeat stars," which have been detected by NASA's Kepler Space Telescope and others. The illustration shows two heartbeat stars swerving close to one another in their closest approach along their highly elongated orbits around one another. The mutual gravitation of the two stars would cause the stars themselves to become slightly ellipsoidal in shape. A third, more distant star in the system is shown in the upper left. Astronomers speculate that such unseen companions may exist in some of these heartbeat star systems, and could be responsible for maintaining these oddly stretched-out orbits. The overlaid curve depicts the inferred cyclic change in velocities in one such system, called KIC 9965691, looking something like the graph of an electrocardiogram (hence the name "heartbeat stars"). The solid points represent measurements made by the HIRES instrument at the W.M. Keck Observatory, and the curve is the best fit model for the motions of this system. http://photojournal.jpl.nasa.gov/catalog/PIA21075

Pictured is an artist's concept of the experimental X-37 Reusable Launch Vehicle re-entering Earth‘s atmosphere. NASA and the Boeing Company entered a cooperative agreement to develop and fly a new experimental space plane called the X-37 that would be ferried into orbit to test new technologies. The reusable space plane incorporated technologies aimed at significantly cutting the cost of space flight. The X-37 would be carried into orbit by the Space Shuttle or be launched by an expendable rocket. After the X-37 was deployed, it would remain in orbit up to 21 days, performing a variety of experiments before re-entering the Earth's atmosphere and landing. The X-37 program was discontinued in 2003.

An artist concept of the Ocean Surface Topography Mission/Jason 2 Earth satellite. The Ocean Surface Topography Mission/Jason 2 is an Earth satellite designed to make observations of ocean topography for investigations into sea-level rise and the relationship between ocean circulation and climate change. The satellite also provides data on the forces behind such large-scale climate phenomena as El Niño and La Niña. The mission is a follow-on to the French-American Jason 1 mission, which began collecting data on sea-surface levels in 1992. http://photojournal.jpl.nasa.gov/catalog/PIA18158

This artist's concept shows NASA's Spitzer Space Telescope. Spitzer begins its "Beyond" mission phase on Oct. 1, 2016. Spitzer is depicted in the orientation it assumes to establish communications with ground stations. Spitzer is over 130 million miles (210 million kilometers) away from Earth, or about 1.5 times the distance between Earth and the Sun. The selected research proposals for Spitzer's Beyond phase include a variety of objects that the mission was not originally planned to address -- such as galaxies in the early universe, the black hole at the center of the Milky Way and exoplanets. Spitzer faces increasing challenges and risks in its Beyond phase. To enable this riskier mode of operations, the mission team will have to override some autonomous safety systems. Mission engineers are hard at work preparing for these new challenges. http://photojournal.jpl.nasa.gov/catalog/PIA20913

This artist's concept of a lake at the north pole of Saturn's moon Titan illustrates raised rims and rampartlike features such as those seen by NASA's Cassini spacecraft around the moon's Winnipeg Lacus. New research using Cassini radar data and modeling proposes that lake basins like these are likely explosion craters, which could have formed when liquid molecular nitrogen deposits within the crust warmed and quickly turned to vapor, blowing holes in the moon's crust. This would have happened during a warming event (or events) that occurred in a colder, nitrogen-dominated period in Titan's past. The new research may provide evidence of these cold periods in Titan's past, followed by a relative warming to conditions like those of today. Although Titan is frigid compared to Earth, methane in the atmosphere provides a greenhouse effect that warms the moon's surface. https://photojournal.jpl.nasa.gov/catalog/PIA23172

This artist concept shows K2-138, the first multi-planet system discovered by citizen scientists. The central star is slightly smaller and cooler than our Sun. The five known planets are all between the size of Earth and Neptune. Planet b may potentially be rocky, but planets c, d, e, and f likely contain large amounts of ice and gas. All five planets have orbital periods shorter than 13 days and are all incredibly hot, ranging from 800 to 1,800 degrees Fahrenheit. https://photojournal.jpl.nasa.gov/catalog/PIA22088

An artist's concept illustrates the positions of the Voyager spacecraft in relation to structures formed around our Sun by the solar wind. Also illustrated is the termination shock, a violent region the spacecraft must pass through before reaching the outer limits of the solar system. At the termination shock, the supersonic solar wind abruptly slows from an average speed of 400 kilometers per second to less than 100 kilometer per second (900,000 to less than 225,000 miles per hour). Beyond the termination shock is the solar system's final frontier, the heliosheath, a vast region where the turbulent and hot solar wind is compressed as it presses outward against the interstellar wind that is beyond the heliopause. A bow shock likely forms as the interstellar wind approaches and is deflected around the heliosphere, forcing it into a teardrop-shaped structure with a long, comet-like tail. The exact location of the termination shock is unknown, and it originally was thought to be closer to the Sun than Voyager 1 currently is. As Voyager 1 cruised ever farther from the Sun, it confirmed that all the planets are inside an immense bubble blown by the solar wind and the termination shock was much more distant. http://photojournal.jpl.nasa.gov/catalog/PIA04927

Its findings will improve understanding about the evolution of our inner solar system's rocky planets, including Earth. The lander will be the first mission to permanently deploy instruments directly onto Martian ground using a robotic arm. The two instruments to be placed into a work area in front of the lander are a seismometer (contributed by the French space agency Centre National d'Études Spatiales, or CNES) to measure the microscopic ground motions from distant marsquakes providing information about the interior structure of Mars, and a heat-flow probe (contributed by the German Aerospace Center, or DLR) designed to hammer itself 3 to 5 meters (about 16 feet) deep and monitor heat coming from the planet's interior. The mission will also track the lander's radio to measure wobbles in the planet's rotation that relate to the size of its core and a suite of environmental sensors to monitor the weather and variations in the magnetic field. Two cameras will aid in instrument deployment and monitoring the local environment. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA19811

This artist's rendering illustrates a conceptual design for a potential future mission to land a robotic probe on the surface of Jupiter's moon Europa. The lander is shown with a sampling arm extended, having previously excavated a small area on the surface. The circular dish on top is a dual-purpose high-gain antenna and camera mast, with stereo imaging cameras mounted on the back of the antenna. Three vertical shapes located around the top center of the lander are attachment points for cables that would lower the rover from a sky crane, which is envisioned as the landing system for this mission concept. http://photojournal.jpl.nasa.gov/catalog/PIA21048

This artist's concept depicts NASA's Mars 2020 rover on the surface of Mars. The mission takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside on the surface of Mars. A future mission could potentially return these samples to Earth. Mars 2020 is targeted for launch in July/August 2020 aboard an Atlas V 541 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. https://photojournal.jpl.nasa.gov/catalog/PIA21635

Scientists using data from NASA's Kepler mission have confirmed the first near-Earth-size planet orbiting in the habitable zone of a sun-like star. The habitable zone is the region around a star where temperatures are just right for water to exist in its liquid form. The artist's concept compares Earth (left) to the new planet, called Kepler-452b, which is about 60 percent larger. The illustration represents one possible appearance for Kepler-452b -- scientists do not know whether the planet has oceans and continents like Earth. Both planets orbit a G2-type star of about the same temperature; however, the star hosting Kepler-452b is 6 billion years old, 1.5 billion years older than our sun. As stars age, they become larger, hotter and brighter, as represented in the illustration. Kepler-452b's star appears a bit larger and brighter. http://photojournal.jpl.nasa.gov/catalog/PIA19825

Shown is a concept illustration of the Ares I crew launch vehicle during launch and the Ares V cargo launch vehicle on the launch pad. Ares I will carry the Orion Crew Exploration Vehicle with an astronaut crew to Earth orbit. Ares V will deliver large-scale hardware to space. This includes the Altair Lunar Lander, materials for establishing an outpost on the moon, and the vehicles and hardware needed to extend a human presence beyond Earth orbit.

In this artist's concept, NASA's Ingenuity Mars Helicopter stands on the Red Planet's surface as NASA's Mars 2020 Perseverance rover (partially visible on the left) rolls away. Ingenuity, a technology experiment, will be the first aircraft to attempt controlled flight on another planet. It will arrive on Mars on Feb. 18, 2021, attached to the belly of NASA's Perseverance rover. Perseverance will deploy Ingenuity onto the surface of Mars, and Ingenuity is expected to attempt its first flight test in spring 2021. https://photojournal.jpl.nasa.gov/catalog/PIA23720

This artist concept depicts a distant hypothetical solar system, similar in age to our own. Looking inward from the system outer fringes, a ring of dusty debris can be seen, and within it, planets circling a star the size of our Sun. This debris is all that remains of the planet-forming disk from which the planets evolved. Planets are formed when dusty material in a large disk surrounding a young star clumps together. Leftover material is eventually blown out by solar wind or pushed out by gravitational interactions with planets. Billions of years later, only an outer disk of debris remains. These outer debris disks are too faint to be imaged by visible-light telescopes. They are washed out by the glare of the Sun. However, NASA's Spitzer Space Telescope can detect their heat, or excess thermal emission, in infrared light. This allows astronomers to study the aftermath of planet building in distant solar systems like our own. http://photojournal.jpl.nasa.gov/catalog/PIA07096

This diagram, superimposed on a photo of Martian landscape, illustrates a concept called "adaptive caching," which is in development for NASA's 2020 Mars rover mission. In addition to the investigations that the Mars 2020 rover will conduct on Mars, the rover will collect carefully selected samples of Mars rock and soil and cache them to be available for possible return to Earth if a Mars sample-return mission is scheduled and flown. Each sample will be stored in a sealed tube. Adaptive caching would result in a set of samples, up to the maximum number of tubes carried on the rover, being placed on the surface at the discretion of the mission operators. The tubes holding the collected samples would not go into a surrounding container. In this illustration, green dots indicate "regions of interest," where samples might be collected. The green diamond indicates one region of interest serving as the depot for the cache. The green X at upper right represents the landing site. The solid black line indicates the rover's route during its prime mission, and the dashed black line indicates its route during an extension of the mission.

This animated artist's concept depicts three small rovers – part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration headed for the Moon – driving together on the lunar surface. Motiv Space Systems in Pasadena, California, created the rendering and collaborated with NASA's Jet Propulsion Laboratory on critical rover and mobility functions. Slated to arrive aboard a lunar lander at the Reiner Gamma region of the Moon under NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers. A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard the lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions. Motiv contributed subsystems and hardware elements for three of four CADRE systems, including designing and building the mobility system and rover chassis, the base station, the rover deployers, and the motor controller boards. The company also procured and tested the actuators with the flight motor controller boards. Animation available at https://photojournal.jpl.nasa.gov/catalog/PIA26296

This artist's concept depicts the stationary NASA Mars lander known by the acronym InSight at work studying the interior of Mars. The InSight mission (for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) is scheduled to launch in March 2016 and land on Mars six months later. It will investigate processes that formed and shaped Mars and will help scientists better understand the evolution of our inner solar system's rocky planets, including Earth. InSight will deploy two instruments to the ground using a robotic arm: a seismometer (contributed by the French space agency Centre National d'Etudes Spatiales, or CNES) to measure the microscopic ground motions from distant marsquakes, providing detailed information about the interior structure of Mars; and a heat-flow probe (contributed by the German Aerospace Center, or DLR) designed to hammer itself 3 to 5 meters (about 16 feet) deep and monitor heat coming from the planet's interior. The mission will also track the lander's radio to measure wobbles in the planet's rotation that relate to the size of its core and will include a camera and a suite of environmental sensors to monitor the weather and variations in the magnetic field. Lockheed Martin Space Systems, Denver, is building the spacecraft. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA17358

This artist's concept summarizes our understanding of how the inside of Ceres could be structured, based on the data returned by the NASA's Dawn mission. Using information about Ceres' gravity and topography, scientists found that Ceres is "differentiated," which means that it has compositionally distinct layers at different depths. The most internal layer, the "mantle" is dominated by hydrated rocks, like clays. The external layer, the 24.85-mile (40-kilometer) thick crust, is a mixture of ice, salts, and hydrated minerals. Between the two is a layer that may contain a little bit of liquid rich in salts, called brine. It extends down at least 62 miles (100 kilometers). The Dawn observations cannot "see" below about 62 miles (100 kilometers) in depth. Hence, it is not possible to tell if Ceres' deep interior contains more liquid or a core of dense material rich in metal. https://photojournal.jpl.nasa.gov/catalog/PIA22660
