A sea of dark dunes, sculpted by the wind into long lines, surrounds Mars' northern polar cap and covers an area as big as Texas. In this false-color image, areas with cooler temperatures are recorded in bluer tints, while warmer features are depicted in yellows and oranges. Thus, the dark, sun-warmed dunes glow with a golden color. This image covers an area 19 miles (30 kilometers) wide.
This scene combines images taken during the period from December 2002 to November 2004 by the Thermal Emission Imaging System instrument on the Mars Odyssey orbiter. It is part of a special set of images marking the 20th anniversary of Odyssey, the longest-working Mars spacecraft in history. The pictured location on Mars is 80.3 degrees north latitude, 172.1 degrees east longitude.

Following the completion of critical mirror alignment steps, NASA’s James Webb Space Telescope team expects that Webb’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve.
On March 11, the Webb team completed the stage of alignment known as “fine phasing.” At this key stage in the commissioning of Webb’s Optical Telescope Element, every optical parameter that has been checked and tested is performing at, or above, expectations. The team also found no critical issues and no measurable contamination or blockages to Webb’s optical path. The observatory is able to successfully gather light from distant objects and deliver it to its instruments without issue.
Although there are months to go before Webb ultimately delivers its new view of the cosmos, achieving this milestone means the team is confident that Webb’s first-of-its-kind optical system is working as well as possible.

This week in 1973, the uncrewed Skylab was launched aboard a modified Saturn V rocket from NASA's Kennedy Space Center. The initial concept for the orbital workshop was devised at NASA's Marshall Space Flight Center. The center also managed the development of Skylab hardware and experiments. Over the course of its human occupation from May 25, 1973 to February 8, 1974, three crews visited Skylab and carried out 270 scientific and technical investigations and logged a combined 171 days in orbit. Today, the Payload Operations Integration Center at Marshall serves as "science central" for the International Space Station, working 24/7, 365 days a year in support of the orbiting laboratory's science experiments. After 20 years of continuous human presence, the space station remains the sole space-based proving ground and stepping stone toward achieving the goals of the Artemis program. The NASA History Program is responsible for generating, disseminating, and preserving NASA's remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological, and scientific aspects of NASA's activities in aeronautics and space.

How massive can a normal star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, making it one of the most massive stars known. This star is the brightest object located just above the gas front in the featured image. Close inspection of images taken with the Hubble Space Telescope, however, have shown that Pismis 24-1 derives its brilliant luminosity not from a single star but from three at least. Component stars would still remain near 100 solar masses, making them among the more massive stars currently on record. Toward the bottom of the image, stars are still forming in the associated emission nebula NGC 6357. Appearing perhaps like a Gothic cathedral, energetic stars near the center appear to be breaking out and illuminating a spectacular cocoon.

Research reveals a new explanation for how the icy shell of Jupiter’s moon Europa rotates at a different rate than its interior. NASA’s Europa Clipper will take a closer look. NASA scientists have strong evidence that Jupiter’s moon Europa has an internal ocean under its icy outer shell – an enormous body of salty water swirling around the moon’s rocky interior. New computer modeling suggests the water may actually be pushing the ice shell along, possibly speeding up and slowing down the rotation of the moon’s icy shell over time.
This view of Jupiter’s icy moon Europa was captured by the JunoCam imager aboard NASA’s Juno spacecraft during the mission’s close flyby on Sept. 29, 2022. The agency’s Europa Clipper spacecraft will explore the moon when it reaches orbit around Jupiter in 2030.

The interaction of two doomed stars has created this spectacular ring adorned with bright clumps of gas -– a diamond necklace of cosmic proportions. Fittingly known as the “Necklace Nebula,” this planetary nebula is located 15,000 light-years away from Earth in the small, dim constellation of Sagitta (the Arrow).
A pair of tightly orbiting Sun-like stars produced the Necklace Nebula, which also goes by the less glamorous name of PN G054.203.4. Roughly 10,000 years ago, one of the aging stars expanded and engulfed its smaller companion, creating something astronomers call a “common envelope.” The smaller star continued to orbit inside its larger companion, increasing the bloated giant’s rotation rate until large parts of it spun outwards into space. This escaping ring of debris formed the Necklace Nebula, with particularly dense clumps of gas forming the bright “diamonds” around the ring.
The pair of stars which created the Necklace Nebula remain so close together – separated by only several million miles – that they appear as a single bright dot in the center of this image. Despite their close encounter, the stars are still furiously whirling around each other, completing an orbit in just over a day.

A full Moon is in view from Launch Complex 39B at NASA’s Kennedy Space Center in Florida on June 14, 2022. The Artemis I Space Launch System (SLS) and Orion spacecraft, atop the mobile launcher, are being prepared for a wet dress rehearsal to practice timelines and procedures for launch. The first in an increasingly complex series of missions, Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and first person of color on the lunar surface, paving the way for a long-term lunar presence and using the Moon as a steppingstone on the way to Mars. The next wet dress rehearsal attempt for the #Artemis I mission is set to begin tomorrow with a “call to stations”. Although the first flight of NASA’s Space Launch System rocket and Orion spacecraft will not have a crew of astronauts on board, there are several experienced teams of people behind the mission.

The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an inky black backdrop at the bottom of the image. JO206 lies over 700 million light-years from Earth in the constellation Aquarius.
Jellyfish galaxies are so-called because of their resemblance to their aquatic namesakes. In the bottom right of this image, long tendrils of bright star formation trail the disk of JO206, just as jellyfish trail tentacles behind them. The tendrils of jellyfish galaxies are formed by the interaction between galaxies and the intra-cluster medium, a tenuous superheated plasma that pervades galaxy clusters. As galaxies move through galaxy clusters, they ram into the intracluster medium, which strips gas from the galaxies and draws it into the long tendrils of star formation.
The tentacles of jellyfish galaxies give astronomers a unique opportunity to study star formation under extreme conditions, far from the influence of the galaxy’s main disk. Surprisingly, Hubble revealed that there are no striking differences between star formation in the disks of jellyfish galaxies and star formation in their tentacles, which suggests the environment of newly formed stars has only a minor influence on their formation.

This latest image of Jupiter, taken by NASA’s Hubble Space Telescope on Aug. 25, 2020, was captured when the planet was 406 million miles from Earth. A unique and exciting detail of Hubble’s snapshot appears at mid-northern latitudes as a bright, white, stretched-out storm traveling around the planet at 350 mph. Hubble shows that the Great Red Spot, rolling counterclockwise in the planet’s southern hemisphere, is plowing into the clouds ahead of it, forming a cascade of white and beige ribbons. Jupiter’s icy moon Europa, thought to hold potential ingredients for life, is visible to the left of the gas giant.

This stunning compilation image of Jupiter’s stormy northern hemisphere was captured by NASA’s Juno spacecraft as it performed a close pass of the gas giant planet. Some bright-white clouds can be seen popping up to high altitudes on the right side of Jupiter’s disk. (The Juno team frequently refers to clouds like these as “pop-up” clouds in image captions.)
Juno took the four images used to produce this color-enhanced view on May 29, 2019, between 12:52 a.m. PDT (3:52 a.m. EDT) and 1:03 a.m. PDT (4:03 a.m. EDT), as the spacecraft performed its 20th science pass of Jupiter. At the time the images were taken, the spacecraft was between 11,600 miles (18,600 kilometers) and 5,400 miles (8,600 kilometers) above Jupiter's cloud tops, above a northern latitude spanning from about 59 to 34 degrees.

Hurricanes are the most powerful weather event on Earth. The 2022 Atlantic hurricane season extends from June 1 to November 30.
Faster than a cheetah, the fastest animal on land, hurricanes produce winds of 74 miles an hour (119 kilometers per hour) or more.
In this image from 2021, the crew aboard the International Space Station snapped this image of Hurricane Sam as it churned in the Atlantic Ocean while the station orbited 259 miles above Trinidad and Tobago.

Jupiter's volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA's Juno spacecraft. As with solar eclipses on the Earth, within the dark circle racing across Jupiter's cloud tops one would witness a full solar eclipse as Io passes in front of the Sun.
Such events occur frequently on Jupiter because it is a large planet with many moons. In addition, unlike most other planets in our solar system, Jupiter's axis is not highly tilted relative to its orbit, so the Sun never strays far from Jupiter's equatorial plane (+/- 3 degrees). This means Jupiter's moons regularly cast their shadows on the planet throughout its year.
Juno's close proximity to Jupiter provides an exceptional fish-eye view, showing a small fraction near the planet's equator. The shadow is about 2,200 miles (3,600 kilometers) wide, approximately the same width as Io, but appears much larger relative to Jupiter.

The Sun emitted a strong solar flare on Tuesday, May 10, 2022, peaking at 9:55 a.m. EDT. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.
This flare is classified as an X-class flare. X-class denotes the most intense flares, while the number provides more information about its strength.

Can stars, like caterpillars, transform themselves into butterflies? No, but in the case of the Butterfly Nebula -- it sure looks like it. Though its wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees, C, the dying central star of NGC 6302, the featured planetary nebula, has become exceptionally hot, shining brightly in visible and ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up was recorded by the Hubble Space Telescope and is reprocessed here to show off the remarkable details of the complex planetary nebula, highlighting in particular light emitted by iron, shown in red. NGC 6302 lies about 4,000 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius). Planetary nebulas evolve from outer atmospheres of stars like our Sun, but usually fade in about 20,000 years.

This 2014 mosaic of Caloris basin is an enhanced-color composite overlain on a monochrome mosaic featured in a previous post. The color mosaic is made up of WAC images obtained when both the spacecraft and the Sun were overhead, conditions best for discerning variations in albedo, or brightness. The monochrome mosaic is made up of WAC and NAC images obtained at off-vertical Sun angles (i.e., high incidence angles) and with visible shadows so as to reveal clearly the topographic form of geologic features. The combination of the two datasets allows the correlation of geologic features with their color properties. In portions of the scene, color differences from image to image are apparent. Ongoing calibration efforts by the MESSENGER team strive to minimize these differences. Caloris basin has been flooded by lavas that appear orange in this mosaic. Post-flooding craters have excavated material from beneath the surface. The larger of these craters have exposed low-reflectance material (blue in this mosaic) from beneath the surface lavas, likely giving a glimpse of the original basin floor material. Analysis of these craters yields an estimate of the thickness of the volcanic layer: 2.5-3.5 km (1.6-2.2 mi.). The MESSENGER spacecraft was the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. In the mission's more than three years of orbital operations, MESSENGER acquired over 250,000 images and extensive other data sets. MESSENGER was deorbited and and impacted the planet’s surface April 30, 2015.

It’s time again for one of the biggest meteor showers of the year! The Perseids are already showing up in our night skies—and when they peak in mid-August, it’s likely to be one of our most impressive skywatching opportunities for a while.
Our meteor-tracking cameras spotted their first Perseid on July 26, but your best chance to see them will start the night of Aug. 11. With the crescent moon setting early, the skies will be dark for the peak viewing hours of midnight (local time) to dawn on Aug. 12.
If you’re in the Northern Hemisphere, and far away from light pollution, you might spot more than 40 Perseids an hour! (If you’re in a city, you may only see a few every hour; skywatchers in the Southern Hemisphere will also see fewer Perseids, with none visible below about 30 degrees south latitude.) The night of Aug. 12-13 will be another great opportunity to see the Perseids: with a full Moon (and lower meteor activity) during the Perseids’ peak in 2022 and a waning crescent high in the sky for 2023, this might be your best chance to do some summer skywatching for a few years.
Find somewhere comfortable, avoiding bright lights as much as possible (yes, including your phone), and give your eyes some time to adjust to the dark—up to half an hour if you can. The Perseids will appear as quick, small streaks of light: they get their name because they look like they’re coming from the direction of the constellation Perseus (near Aries and Taurus in the night sky), but Perseids in that area can be hard to spot from the perspective of Earth. So just look up and enjoy the show!
In this 30 second exposure taken with a circular fish-eye lens, a meteor streaks across the sky during the annual Perseid meteor shower on Friday, Aug. 12, 2016 in Spruce Knob, West Virginia.

This image, taken with the NASA/ESA Hubble Space Telescope, depicts a special class of star-forming nursery known as Free-floating Evaporating Gaseous Globules, or frEGGs for short. This object is formally known as J025157.5+600606.
When a massive new star starts to shine while still within the cool molecular gas cloud from which it formed, its energetic radiation can ionize the cloud’s hydrogen and create a large, hot bubble of ionized gas. Amazingly, located within this bubble of hot gas around a nearby massive star are the frEGGs: dark compact globules of dust and gas, some of which are giving birth to low-mass stars. The boundary between the cool, dusty frEGG and the hot gas bubble is seen as the glowing purple/blue edges in this fascinating image.

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas – the raw material for building new stars. This etching process sculpts a fantasy landscape where human imagination can see all kinds of shapes and figures. This nebula in the constellation of Cassiopeia has flowing veils of gas and dust that have earned it the nickname "Ghost Nebula."
Officially known as IC 63, this nebula is located 550 light-years away in the constellation Cassiopeia the Queen.

Today in 1971, Apollo 15 astronauts David Scott and James Irwin became the first humans to drive a car on the lunar surface, the Lunar Roving Vehicle. The lightweight, electric car greatly increased the range of mobility and productivity on the scientific traverses for astronauts. The LRV weighed 462 pounds (77 pounds on the Moon) and could carry two suited astronauts, their gear and cameras, and several hundred pounds of bagged lunar samples. The LRV was designed and developed by NASA's Marshall Space Flight Center and built by Boeing. Here, David Scott waits in the LRV for the return trip to the Lunar Module, Falcon, with rocks and soil collected near the Hadley-Apennine landing site. Today, Marshall is playing a vital role in the Artemis program by developing the Space Launch System, the backbone of NASA's exploration plans and the only rocket capable of sending humans to the Moon and Mars.

A dramatic triplet of galaxies takes center stage in this image from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational tug-of-war between interacting galaxies. This system – known as Arp 195 – is featured in the Atlas of Peculiar Galaxies, a list which showcases some of the weirder and more wonderful galaxies in the universe. Observing time with Hubble is extremely valuable, so astronomers don't want to waste a second. The schedule for Hubble observations is calculated using a computer algorithm which allows the spacecraft to occasionally gather bonus snapshots of data between longer observations. This image of the clashing triplet of galaxies in Arp 195 is one such snapshot. Extra observations such as these do more than provide spectacular images – they also help to identify promising targets to follow up with using telescopes such as the upcoming NASA/ESA/CSA James Webb Space Telescope.

Lying inside our home galaxy, the Milky Way, this Herbig–Haro object is a turbulent birthing ground for new stars in a region known as the Orion B molecular cloud complex, located 1,350 light-years away.
Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars that form when narrow jets of partially ionized gas ejected by stars collide with nearby clouds of gas and dust. This image of Herbig-Haro Jet HH 24 was taken by the Hubble Space Telescope in 2015.
When stars form within giant clouds of cool molecular hydrogen, some of the surrounding material collapses under gravity to form a rotating, flattened disk encircling the newborn star.
Although planets will later congeal in the disk, at this early stage the protostar is feeding on the disk with a voracious appetite. Gas from the disk rains down onto the protostar and engorges it. Superheated material spills away and is shot outward from the star in opposite directions along an uncluttered escape route – the star's rotation axis.
Shock fronts develop along the jets and heat the surrounding gas to thousands of degrees Fahrenheit. The jets collide with the surrounding gas and dust and clear vast spaces, like a stream of water plowing into a hill of sand.

Resting on the tail of the Great Bear in the constellation of Ursa Major lies NGC 5585, a spiral galaxy that is more than it appears.
The many stars and clouds of dust and gas that make up NGC 5585, shown here in this Hubble image, contribute only a small fraction of the total mass of the galaxy. As in many galaxies, this discrepancy can be explained by the abundant yet seemingly invisible presence of dark matter, a mysterious material that astronomers can’t directly observe.
The stellar disk of the galaxy extends over 35,000 light-years across. When compared with galaxies of a similar shape and size, NGC 5585 stands out by having a notably different composition. Contributing to the total mass of the galaxy, it contains a far higher proportion of dark matter.
Hot spots of star formation can be seen along the galaxy’s faint spiral arms. These regions shine a brilliant blue, contrasting strikingly against the ever-black background of space.

Some of the most stunning views of our sky occur at sunset, when sunlight pierces the clouds, creating a mixture of bright and dark rays formed by the clouds' shadows and the beams of light scattered by the atmosphere.
Astronomers studying nearby galaxy IC 5063 are tantalized by a similar effect in images taken by NASA's Hubble Space Telescope. In this case, a collection of narrow bright rays and dark shadows is seen beaming out of the blazingly bright center of the active galaxy.

A paddlewheeler makes its way up the Mississippi River as the Moon rises over New Orleans on Sunday evening, Aug. 22, 2021. The August Sturgeon Moon, which was also a rare Blue Moon, was full at 7:02 a.m. local time Sunday but the nearly full Moon still put on a show when it rose over New Orleans later that evening. New Orleans is home to the NASA Michoud Assembly Facility, where the core stage of the Space Launch System that will return people to the Moon was built.

About 10,000 years ago, light from the explosion of a giant star in the constellation Vela arrived at Earth. This supernova left behind a dense object called a pulsar, which appears to brighten regularly as it spins, like a cosmic lighthouse. From the surface of this pulsar, winds of particles emerge that travel near the speed of light, creating a chaotic hodgepodge of charged particles and magnetic fields that crash into surrounding gas. This phenomenon is called a pulsar wind nebula.
In this new image, the hazy light blue halo corresponds to the first-ever X-ray polarization data for Vela, which comes from NASA’s Imaging X-ray Polarimetry Explorer, or IXPE. A faint blue fuzzy line pointing to the upper right-hand corner corresponds to a jet of high-energy particles shooting out from the pulsar at about half the speed of light. The pink X-ray "arcs" are thought to mark the edges of donut-shaped regions where the pulsar wind shocks and accelerates high-energy particles. The pulsar itself is located at the white circle at the center of the image.
Light blue represents X-ray polarization data from NASA’s Imaging X-ray Polarimetry Explorer. Pink and purple colors correspond to data from NASA’s Chandra X-Ray observatory, which has observed Vela several times previously. NASA’s Hubble Space Telescope contributed the stars in the background.

NASA's Oceans Melting Greenland, or OMG, airborne mission found that most of Greenland's glaciers that empty into the ocean are at greater risk of rapid ice loss than previously understood. OMG's six-year field campaign studied the ocean's role in glacial ice loss by gathering precise measurements of ocean depth, temperature, and salinity in front of more than 220 glaciers. The mission's goal was to clarify our understanding of sea level rise over the next 50 years. This photo of Apusiaajik Glacier was taken near Kulusuk, Greenland, on Aug. 26, 2018, during OMG's field operations.

In this spectacular image captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 2799 (on the left) is seemingly being pulled into the center of the galaxy NGC 2798 (on the right).
Interacting galaxies, such as these, are so named because of the influence they have on each other, which may eventually result in a merger or a unique formation. Already, these two galaxies have seemingly formed a sideways waterspout, with stars from NGC 2799 appearing to fall into NGC 2798 almost like drops of water.
Galactic mergers can take place over several hundred million to over a billion years. While one might think the merger of two galaxies would be catastrophic for the stellar systems within, the sheer amount of space between stars means that stellar collisions are unlikely and stars typically drift past each other.

This week in 2007, space shuttle Discovery, mission STS-120, launched from NASA’s Kennedy Space Center on a 15-day mission to the International Space Station. This was the 23rd shuttle mission to the orbiting lab. Discovery carried the Italian-built multiport module, named Harmony, which connected the U.S. segment of the station to the European and Japanese laboratory modules. Today, the Payload Operations Integration Center at NASA’s Marshall Space Flight Center serves as “science central” for the space station, working 24/7, 365 days a year in support of the orbiting laboratory’s science experiments. After 20 years of continuous human presence, the space station remains the sole space-based proving ground and stepping stone toward achieving the goals of the Artemis program.

NASA’s OSIRIS-REx completed its last flyover of Bennu around 6 a.m. EDT (4 a.m. MDT) April 7 and is now slowly drifting away from the asteroid; however, the mission team will have to wait a few more days to find out how the spacecraft changed the surface of Bennu when it grabbed a sample of the asteroid.
This image shows a top-down view of asteroid Bennu, with a portion of the asteroid’s equatorial ridge and northern hemisphere illuminated. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 4, 2021, from a distance of about 186 miles (300 km). The spacecraft’s cameras are pointed directly at Bennu’s north pole. Two large equatorial craters are visible on the asteroid’s edge (center and center left). The image was obtained during the mission’s Post-TAG Operations phase, as the spacecraft slowly approached Bennu in preparation for a final observational flyby on April 7.

This stunning 2005 picture of the supernova remnant Cassiopeia A (Cas A) is a composite of images taken by three of NASA's Great Observatories. Infrared data from the Spitzer Space Telescope are colored red; optical data from the Hubble Space Telescope are yellow; and X-ray data from the Chandra X-ray Observatory are green and blue.
Cas A is the 300-year-old remnant created by the supernova explosion of a massive star. Each Great Observatory image highlights different characteristics of the remnant. Spitzer reveals warm dust in the outer shell with temperatures of about 10 degrees Celsius (80 degrees Fahrenheit), and Hubble sees the delicate filamentary structures of warmer gases about 10,000 degrees Celsius. Chandra shows hot gases at about 10 million degrees Celsius. This hot gas was created when ejected material from the supernova smashed into surrounding gas and dust at speeds of about ten million miles per hour.
A comparison of the infrared and X-ray images of Cas A should enable astronomers to better understand how relatively cool dust grains can coexist in the superhot gas that produces the X-rays. It should also help to determine whether most of the dust in the supernova remnant came from the massive star before it exploded, or from the rapidly expanding supernova ejecta.
The turquoise dot at the center of the shell may be a neutron star created during the supernova. Blue Chandra data were acquired using broadband X-rays (low through high energies); green Chandra data correspond only to intermediate energy X-rays; yellow Hubble data were taken using a 900 nanometer-wavelength filter, and red Spitzer data are from the telescope's 24-micron detector.

Captured on Oct. 20, 2020 during the OSIRIS-REx mission’s Touch-And-Go (TAG) sample collection event, this series of images shows the SamCam imager’s field of view as the NASA spacecraft approaches and touches down on asteroid Bennu’s surface, over 200 million miles (321 million km) away from Earth. The sampling event brought the spacecraft all the way down to sample site Nightingale, touching down within three feet (one meter) of the targeted location. The team on Earth received confirmation at 6:08 p.m. EDT that successful touchdown occurred. Preliminary data show the one-foot-wide (0.3-meter-wide) sampling head touched Bennu’s surface for approximately 6 seconds, after which the spacecraft performed a back-away burn.

This week in 1997, the Fastrac engine was duration tested in Test Stand 116 at NASA’s Marshall Space Flight Center. The overall purpose of this test was to gauge the length of time between contact of triethylaluminum and liquid oxygen as an ignitor for the engine. Initially developed for use with the first powered flight of NASA’s X-34 technology demonstrator, the Fastrac engine was capable of producing 60,000 pounds of thrust. Today, Marshall is playing a vital role in the Artemis program by developing the Space Launch System, the backbone of NASA’s exploration plans and the only rocket capable of sending humans to the Moon and Mars.
