Sewing Spacecraft Blankets for NASA’s Europa Clipper Mission to Planet Jupiter
See how a team at NASA’s Jet Propulsion Laboratory (JPL) sews and installs thermal blankets to protect the agency’s Europa Clipper spacecraft from the cold and harsh environment it will face around Jupiter as it investigates the planet’s ice-encrusted ocean moon Europa.
In this episode of the Spacecraft Makers video series, Mark Duran and Morgan Betsill provide a behind-the-scenes look at JPL’s “Shield Shop,” where layers of the thermal blankets come together before they are installed on the spacecraft. Then, these custom blankets are carefully fitted onto the spacecraft in a clean room at JPL.
Spacecraft Makers is a video series that takes audiences behind the scenes to learn more about how space missions, like Europa Clipper, come together. Europa Clipper will explore this icy moon of Jupiter to see if there are conditions suitable for life. The spacecraft needs to be hardy enough to survive a 1.6 billion-mile, six-year journey to Jupiter—and sophisticated enough to perform a detailed science investigation of Europa once it arrives at the Jupiter system in 2030.
Europa Clipper is expected to launch in October 2024 from Kennedy Space Center in Florida.
Nebula NGC 6164-5 in Norma | Gemini South Observatory
Nebula NGC 6164-5 imaged by the Gemini South Observatory in Chile, South America. The emission nebula NGC 6164-5 is a rectangular, bipolar cloud with rounded corners and a diagonal bar producing an inverted S-shaped appearance. It lies about 4,200 light-years away in the constellation Norma.
The nebula measures about 4.2 light-years across, and contains gases ejected by the star HD 148937 at its heart. This star is 40 times more massive than the Sun, and at about three to four million years of age, is past the middle of its life span. Stars this massive usually live to be only about six million years old, so HD 148397 is aging fast. It will likely end its life in a violent supernova explosion.

Artemis II will be NASA’s first crewed flight test of the Space Launch System (SLS) rocket and Orion spacecraft around the Moon to verify today’s capabilities for humans to explore deep space and pave the way for long-term exploration and science on the lunar surface.
Celebrating the International Space Station's 25th Anniversary (1998-2023)
Twenty-five years ago this week, the first two modules of the International Space Station—Zarya and Unity—were mated during the STS-88 mission of space shuttle Endeavour. The shuttle’s Canadarm robotic arm reached out and grappled Zarya that had been on orbit just over two weeks, and attached it to the Unity module stowed inside Endeavour’s payload bay. Endeavour would undock from the young dual-module station one week later beginning the space station assembly era.
The seven-member Expedition 70 crew poses for a portrait inside the International Space Station's Kibo laboratory module. In the front row (from left) are, Commander Andreas Mogensen of Denmark from the European Space Agency (ESA) and NASA Flight Engineers Jasmin Moghbeli and Loral O'Hara.

International Space Station's 25th Anniversary (1998-2023): The First Segments
The mated Russian-built Zarya (left) and U.S.-built Unity modules are backdropped against the blackness of space and Earth’s horizon shortly after leaving Endeavour’s cargo bay on Dec. 13, 1998. A few days earlier, on Dec. 6, 1998, the space shuttle Endeavour, mission STS-88, launched from NASA’s Kennedy Space Center in Florida carrying the Unity connecting module and two pressurized mating adapters. The same day, the STS-88 crew captured the Russian Zarya module, launched Nov. 20, and mated it with the Unity node. Unity was the first piece of the International Space Station provided by the United States.
The components in the current space station were built in countries around the world with each piece performing once connected in space by complex robotics systems and humans in spacesuits—a testament to teamwork and cultural coordination.

Orion Spacecraft & The Moon's Ocean of Storms | NASA Artemis I Mission
On Dec. 5, 2022, a camera on board the uncrewed Orion spacecraft captured this view as Orion approached its return powered flyby of the Moon. Beyond one of Orion's extended solar arrays lies dark, smooth, terrain along the western edge of the Oceanus Procellarum. Prominent on the lunar nearside Oceanus Procellarum, the Ocean of Storms, is the largest of the Moon's lava-flooded maria.
The lunar terminator, shadow line between lunar night and day, runs along the left of this frame. The 41 kilometer diameter crater Marius is top center, with ray crater Kepler peeking in at the edge, just right of the solar array wing. Kepler's bright rays extend to the north and west, reaching the dark-floored Marius. By Dec. 11, 2022, the Orion spacecraft had reached its home world. The historic Artemis 1 mission ended with Orion's successful splashdown in planet Earth's water-flooded Pacific Ocean.

Solar Minimum versus Solar Maximum | NASA's Solar Dynamics Observatory
Our Sun is a 4.5 billion-year-old yellow dwarf star—a hot glowing ball of hydrogen and helium—at the center of our solar system. It is about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. The height of the Sun’s activity cycle, known as solar maximum, is a time of greatly increased solar storm activity. Sunspots, eruptions called solar flares, and coronal mass ejections are common at solar maximum.
Although the Sun is the center of our solar system and essential to our survival, it is only an average star in terms of its size. Stars up to 100 times larger have been found. Many solar systems have more than one star. By studying our Sun, scientists can better understand the workings of distant stars.
The Sun orbits the center of the Milky Way, bringing with it the planets, asteroids, comets, and other objects in our solar system. Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). But even at this speed, it takes about 230 million years for the Sun to make one complete trip around the Milky Way.
