A Poem for Jupiter's Ocean Moon Europa by U.S. Poet Laureate Ada Limón | NASA

A Poem for Jupiter's Ocean Moon Europa by U.S. Poet Laureate Ada Limón | NASA

U.S. Poet Laureate Ada Limón wrote an original poem dedicated to NASA’s Europa Clipper mission to Jupiter's moon Europa, which is believed to harbor a vast ocean beneath its icy surface.

Narrated by Limón herself, the poem is entitled “In Praise of Mystery: A Poem for Europa” and it connects two water worlds—Earth, yearning to reach out and understand what makes a world habitable, and Europa, waiting with secrets yet to be explored. The poem will be engraved on a plaque carried aboard the Europa Clipper spacecraft.

The commissioned work was released on June 1, 2023, for NASA’s "Message in a Bottle" campaign, which invites people around the world to sign their names to the poem that will journey to another world. Participants’ names will travel 1.8 billion miles, or 2.89 billion kilometers, aboard the Europa Clipper spacecraft on its voyage to Jupiter and its moons.

The mission is set to launch from NASA’s Kennedy Space Center in October 2024, and reach orbit around Jupiter by 2030. Over several years, it will conduct multiple flybys of Europa, gathering detailed measurements to determine if the moon has conditions suitable for life.

Pluto's Largest Moon Charon | NASA's New Horizons Mission

Pluto's Largest Moon Charon | NASA's New Horizons Mission

A darkened and mysterious north polar region known to some as Mordor Macula caps this high-resolution view of Charon, Pluto's largest moon. It was captured by NASA's New Horizons Mission near the spacecraft's closest approach on July 14, 2015. The combined blue, red, and infrared data was processed to enhance colors and follow variations in Charon's surface properties with a resolution of about 2.9 kilometers (1.8 miles). A stunning image of Charon's Pluto-facing hemisphere, it also features a clear view of an apparently moon-girdling belt of fractures and canyons that seems to separate smooth southern plains from varied northern terrain. Charon is 1,214 kilometers (754 miles) across. This is about 1/10th the size of planet Earth but a whopping 1/2 the diameter of Pluto itself, and makes it the largest satellite relative to its parent body in the Solar System.

New Horizons successfully pulled off the first exploration of the Pluto system in July 2015, followed by the farthest flyby in history—and first close-up look at a Kuiper Belt object (KBO)—with its flight past Arrokoth on New Year’s Day 2019. From its unique perch in the Kuiper Belt, New Horizons is making observations that cannot be made from anywhere else; even the stars look different from the spacecraft’s point of view.

As New Horizons team members use giant telescopes like the Japanese Subaru observatory to scan the skies for another potential (and long-shot) KBO flyby target, New Horizons itself remains healthy, collecting data on the solar wind and space environment in the Kuiper Belt, other KBOs, and distant planets like Uranus and Neptune.

Views of Barred Spiral Galaxy NGC 5068 | Webb Telescope

Views of Barred Spiral Galaxy NGC 5068 | Webb Telescope

This video highlights two views of the barred spiral galaxy NGC 5068 as seen by the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope. The galaxy’s bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.

With its ability to peer through the gas and dust enshrouding newborn stars, the Webb is the perfect telescope to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the European Southern Observatory's Very Large Telescope (VLT). The keen vision at infrared wavelengths of two of Webb’s instruments—MIRI and NIRCam—allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. Both of these views are highlighted in this video.

Star Clusters in Barred Spiral Galaxy NGC 5068 | James Webb Space Telescope

A delicate tracery of dust and bright star clusters threads across this image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.

Image Description: A close-in image of a spiral galaxy, showing its core and part of a spiral arm. Thousands upon thousands of tiny stars that make it up can be seen, most dense in a whitish bar that forms its core. Clumps and filaments of dust form an almost skeletal structure that follows the twist of the galaxy and its spiral arm. Large, glowing bubbles of red gas are hidden in the dust.

With its ability to peer through the gas and dust enshrouding newborn stars, Webb is the perfect telescope to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to observations in visible light, like many from Hubble or the European Southern Observatory's Very Large Telescope (VLT). The keen vision at infrared wavelengths of two of Webb’s instruments—MIRI and NIRCam—allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.

This portrait of NGC 5068 is part of a campaign to create an astronomical treasure trove, a repository of observations of star formation in nearby galaxies. These observations are particularly valuable to astronomers for two reasons. The first is because star formation underpins so many fields in astronomy, from the physics of the tenuous plasma that lies between stars to the evolution of entire galaxies. By observing the formation of stars in nearby galaxies, astronomers hope to kick-start major scientific advances with some of the first available data from Webb.

The second reason is that Webb’s observations build on other studies using telescopes including the NASA/ESA Hubble Space Telescope and some of the world’s most capable ground-based observatories. Webb collected images of 19 nearby star-forming galaxies which astronomers could then combine with catalogs from Hubble of 10,000 star clusters, spectroscopic mapping of 20,000 star-forming emission nebulae from ESO's VLT, and observations of 12,000 dark, dense molecular clouds identified by the Atacama Large Millimeter/submillimeter Array (ALMA). These observations span the electromagnetic spectrum and give astronomers an unprecedented opportunity to piece together the minutiae of star formation.

NASA Artemis V Moon Rocket Engine Test | Preparing for Crewed Missions

NASA Artemis V Moon Rocket Engine Test | Preparing for Crewed Missions

An Aerojet Rocketdyne RS-25 rocket engine (RS-25 Engine 10001) was tested on the Fred Haise Test Stand (formerly A-1 Test Stand) at NASA's John C. Stennis Space Center in Mississippi, on June 1, 2023 at 13:49 ET. This was the ninth hot fire test in a planned 12-test series of the newly redesigned RS-25 engines that will be used beginning with Artemis V. The test had a planned duration of 500 seconds, the same amount of time the engines must fire during an actual flight of NASA’s Space Launch System (SLS).

Lead contractor Aerojet Rocketdyne is using advanced manufacturing techniques, such as 3D printing, to reduce the cost and time needed to build new engines for use on missions beginning with Artemis V. Four RS-25 engines help power SLS at launch, including on its Artemis missions to the Moon.

Through Artemis, NASA is returning humans, including the first woman and the first person of color, to the Moon to explore the lunar surface and prepare for flights to Mars. SLS is the only rocket capable of sending the agency’s Orion spacecraft, astronauts, and supplies to the Moon in a single mission.
