NASA/Frank Michaux On Aug. 21, 2024, engineers and technicians deployed and tested NASA’s Europa Clipper giant solar arrays. Each array measures about 46.5 feet (14.2 meters) long and about 13.5 feet (4.1 meters) high.
Europa Clipper is scheduled to launch Oct. 10, 2024, on the first mission to conduct a detailed science investigation of Jupiter’s moon Europa. Scientists predict Europa has a salty ocean beneath its icy crust that could hold the building blocks necessary to sustain life.

NASA’s Advanced Composite Solar Sail System is seen orbiting Earth in this 13-second exposure photograph, Monday, Sept. 2, 2024, from Arlington, Virginia. The mission team confirmed the spacecraft’s unique composite boom system unfurled its reflective sail on Thursday, Aug. 29, 2024, accomplishing a critical milestone in the agency’s demonstration of next-generation solar sail technology that will allow small spacecraft to “sail on sunlight.” Just as a sailboat is powered by wind in a sail, a spacecraft can use the pressure of sunlight on a solar sail for propulsion. This technology demonstration serves as a pathfinder for future missions powered by solar sail technology.NASA/Bill Ingalls Now that its reflective sail has deployed fully open in orbit, the Advanced Composite Solar Sail System can be seen in the night sky from many locations across the world!
Stargazers can join NASA’s #SpotTheSail campaign by using the NASA app on mobile platforms to find out when the spacecraft will be visible at their location. The app, which is free to use and available on iOS and Android, provides a location-specific schedule of upcoming sighting opportunities. A built-in augmented reality tool points users to the location of the spacecraft in real time.
Can you spot the solar sail? Share your viewing experience online using the hashtag #SpotTheSail for a chance to be featured on NASA’s website and social media channels.
Here’s how to use the sighting prediction tool:
Install and open the NASA app on an iOS or Android device. Tap on the “Featured” tab on the bottom navigation bar. Tap on the Advanced Composite Solar Sail System mission from the Featured Missions at the top of the screen. Tap on the “Sightings” tab on the bottom navigation bar. A list of all the upcoming sightings for your location will be displayed. If you are using an iOS device, you can tap on the “Sky View” link for an augmented reality guide to help you locate the spacecraft’s real-time location during the visible pass. NASA’s Advanced Composite Solar Sail System is testing new technologies in low Earth orbit, including a composite boom system that supports a four-piece sail. Not to be confused with solar panels, solar sails allow small spacecraft to “sail on sunlight,” eliminating the need for rocket fuel or other conventional propellants. This propulsion technology can enable low-cost deep space missions to increase access to space.

NASA, ESA Missions Help Scientists Uncover How Solar Wind Gets Energy
Since the 1960s, astronomers have wondered how the Sun’s supersonic “solar wind,” a stream of energetic particles that flows out into the solar system, continues to receive energy once it leaves the Sun. Now, thanks to a lucky lineup of a NASA and an ESA (European Space Agency)/NASA spacecraft both currently studying the Sun, they may have discovered the answer — knowledge that is a crucial piece of the puzzle to help scientists better forecast solar activity between the Sun and Earth.
A paper published in the Aug. 30, 2024, issue of the journal Science provides persuasive evidence that the fastest solar winds are powered by magnetic “switchbacks,” or large kinks in the magnetic field, near the Sun.
“Our study addresses a huge open question about how the solar wind is energized and helps us understand how the Sun affects its environment and, ultimately, the Earth,” said Yeimy Rivera, co-leader of the study and a postdoctoral fellow at the Smithsonian Astrophysical Observatory, part of Center for Astrophysics | Harvard & Smithsonian. “If this process happens in our local star, it’s highly likely that this powers winds from other stars across the Milky Way galaxy and beyond and could have implications for the habitability of exoplanets.”
This artist’s concept shows switchbacks, or large kinks in the Sun’s magnetic field. NASA’s Goddard Space Flight Center/Conceptual Image Lab/Adriana Manrique Gutierrez Previously, NASA’s Parker Solar Probe found that these switchbacks were common throughout the solar wind. Parker, which became the first craft to enter the Sun’s magnetic atmosphere in 2021, allowed scientists to determine that switchbacks become more distinct and more powerful close to the Sun. Up to now, however, scientists lacked experimental evidence that this interesting phenomenon actually deposits enough energy to be important in the solar wind.
“About three years ago, I was giving a talk about how fascinating these waves are,” said co-author Mike Stevens, astrophysicist at the Center for Astrophysics. “At the end, an astronomy professor stood up and said, ‘that’s neat, but do they actually matter?’”
To answer this, the team of scientists had to use two different spacecraft. Parker is built to fly through the Sun’s atmosphere, or “corona.” ESA’s and NASA’s Solar Orbiter mission is also on an orbit that takes it relatively close to the Sun, and it measures solar wind at larger distances.
The discovery was made possible because of a coincidental alignment in February 2022 that allowed both Parker Solar Probe and Solar Orbiter to measure the same solar wind stream within two days of each other. Solar Orbiter was almost halfway to the Sun while Parker was skirting the edge of the Sun’s magnetic atmosphere.

“We didn’t initially realize that Parker and Solar Orbiter were measuring the same thing at all. Parker saw this slower plasma near the Sun that was full of switchback waves, and then Solar Orbiter recorded a fast stream which had received heat and with very little wave activity,” said Samuel Badman, astrophysicist at the Center for Astrophysics and the other co-lead of the study. “When we connected the two, that was a real eureka moment.”
Scientists have long known that energy is moved throughout the Sun‘s corona and the solar wind, at least in part, through what are known as “Alfvén waves.” These waves transport energy through a plasma, the superheated state of matter that makes up the solar wind.
However, how much the Alfvén waves evolve and interact with the solar wind between the Sun and Earth couldn’t be measured — until these two missions were sent closer to the Sun than ever before, at the same time. Now, scientists can directly determine how much energy is stored in the magnetic and velocity fluctuations of these waves near the corona, and how much less energy is carried by the waves farther from the Sun.
The new research shows that the Alfvén waves in the form of switchbacks provide enough energy to account for the heating and acceleration documented in the faster stream of the solar wind as it flows away from the Sun.
“It took over half a century to confirm that Alfvenic wave acceleration and heating are important processes, and they happen in approximately the way we think they do,” said John Belcher, emeritus professor from the Massachusetts Institute of Technology who co-discovered Alfvén waves in the solar wind but was not involved in this study.
In addition to helping scientists better forecast solar activity and space weather, such information helps us understand mysteries of the universe elsewhere and how Sun-like stars and stellar winds operate everywhere.
“This discovery is one of the key puzzle pieces to answer the 50-year-old question of how the solar wind is accelerated and heated in the innermost portions of the heliosphere, bringing us closer to closure to one of the main science objectives of the Parker Solar Probe mission,” said Adam Szabo, Parker Solar Probe mission science lead at NASA.
