It takes a lot of work to make space missions happen. Hundreds or even thousands of experts work as a team to put together the spacecraft. Then it has to be tested in conditions similar to space, to be sure that it can survive out there once it is launched. Fixing big issues that pop up after launch is either impossible or very difficult, so it is important that everything works before the mission gets to space.
The Parker Solar Probe and Solar Orbiter missions study the Sun from different points of view. Parker is led by NASA and was built to fly into the upper atmosphere of the Sun, called the corona. Solar Orbiter is led by the European Space Agency (ESA) and has gotten our first peek at the Sun’s poles. Together, they both provide a deeper understanding of the Sun and how it affects the rest of the solar system.
A New Way of Seeing
It takes a lot of teamwork to build and launch any space mission, and Solar Orbiter was no different. It also had to go through a lot of testing in conditions similar to outer space before it made its final journey to the launch site.
The Solar Orbiter mission has taken the highest-ever-resolution images of the Sun and recently sent back the first ever close-up images of the Sun’s poles. It has also studied the solar wind to see what it is made of and helped scientists find out where on the Sun the solar wind comes from. Working hand-in-hand with Parker, it has also shown how the solar wind gets a magnetic “push” that increases its total speed.
An infographic showing the ten scientific instruments carried aboard Solar Orbiter European Space Agency To get all of this done, the spacecraft carries ten different scientific instruments on its voyage around the Sun. These instruments work together to provide a total overview of our star. Six of them are remote-sensing instruments (above in gold), which “see” the Sun and return imagery to Earth. The other four are what’s called in-situ instruments (above in pink), which measure the environment all around the spacecraft. This includes the solar wind, and the electric and magnetic fields embedded within it.
Faster and Closer Than Ever Before
The Parker Solar Probe was named for Dr. Eugene N. Parker, who pioneered our modern understanding of the Sun. In the mid-1950s, Parker developed a theory that predicted the solar wind. The probe named after him is designed to swoop within 4 million miles (6.5 million kilometers) of the Sun’s surface to trace its energy flow, to study the heating of the corona, and to explore what accelerates the solar wind.
To get all this done, the probe has to survive the blazing hot corona. It can get up to about 2 million °F (1.1 million °C)! Parker uses high-tech thermal engineering to protect itself, including an eight-foot diameter heat shield called the Thermal Protection System (TPS). The TPS is made of two panels of carbon composite with a lightweight 4.5-inch-thick carbon foam core. This heat shield sandwich keeps things about 85 °F (29 °C) in its shadow, even though the Sun-facing side reaches about 2,500 °F (1,377 °C)!
In 2018, the Parker Solar Probe became the fastest spacecraft ever built, at about 430,000 miles per hour (700,000 kilometers per hour). It also got seven times closer to the Sun than any other spacecraft, getting within 3.8 million miles (6.2 million kilometers). It made this record-breaking close encounter on Christmas Eve of 2024.
From Yesterday to Tomorrow
The Parker Solar Probe was launched on August 12, 2018, and Solar Orbiter was launched on February 10, 2020. Both of them took off from Cape Canaveral Air Station in Florida. Some pieces of Solar Orbiter were transported in trucks, but the completed spacecraft made the journey from Europe to the U.S. on a gigantic Antonov cargo plane designed especially for transporting spacecraft.
Together, these spacecraft have done a lot to improve our knowledge of the Sun. Both missions are currently in their main operational phase, with projected end-of-mission sometime in 2026, and could continue returning data for a few years to come.

NOAA One year ago, solar storms lit up the night sky. Why?
The Sun is 93 million miles away from Earth, on average. Even though it’s far away, we can still see and feel its effects here. One of the most beautiful effects are the auroras – colorful lights that dance across the sky near the North and South Poles. These are also called the Northern and Southern Lights. They happen when tiny particles from the Sun hit gas molecules in our atmosphere and give off energy.
Sometimes the Sun becomes very active and sends out a lot more energy than normal. When this happens, we can see auroras in places much farther from the poles than normal. In May 2024, around Mother’s Day, the Sun sent powerful solar storms in the direction of Earth. These storms were also called the Gannon Storms, named after Jennifer Gannon, a scientist who studied space weather. The Northern Lights could be seen as far south as Puerto Rico, Hawaii, Mexico, Jamaica, and the Bahamas. The Southern Lights were also visible as far north as South Africa and New Zealand.
Aurora Borealis seen from British Columbia, Canada on May 10, 2024. NASA/Mara Johnson-Groh Scientists who study the Sun and its effects on our solar system work in a field called heliophysics. Their studies of the Sun have shown that it goes through cycles of being more active and less active. Each one of these cycles lasts about 11 years, but can be anywhere from 8 to 14 years long. This is called the Solar Cycle.
The middle of each cycle is called Solar Maximum. During this time, the Sun has more dark spots (called sunspots) and creates more space weather events. The big storms in May 2024 happened during the Solar Maximum for Solar Cycle 25.
On May 8 and 9, 2024, an active area on the Sun called AR3664 shot out powerful solar flares and several huge bursts of energy called coronal mass ejections (CMEs). These CMEs headed straight for Earth. The first CME pushed aside the normal solar wind, making a clear path for the others to reach us faster. When all this energy hit our atmosphere, it created auroras much farther from the poles than usual. It was like the Sun gave the auroras a huge power boost!
Eruptions of Solar material into space as seen on May 7 (right) and May 8 (left), 2024. These types of eruptions often come just before a larger Coronal Mass Ejection (CME), including the ones which caused the Mother’s Day solar storms. NASA/SDO Auroras are beautiful to watch, but the space weather that creates them can also cause problems. Space weather can mess up radio signals, power grids, GPS systems, and satellites. During the May 2024 storms, GPS systems used by farmers were disrupted. Many farmers use GPS to guide their self-driving tractors. Since this happened during peak planting season, it may have cost billions of dollars in lost profit.
Because space weather can cause so many problems, scientists at NASA and around the world watch the Sun closely to predict when these events will happen. You can help too! Join local science projects at schools, teach others about the Sun, and help make observations in your area. All of this helps us to learn more about the Sun and how it affects our planet.

Video: 00:03:30 Two meteorological missions – Meteosat Third Generation Sounder-1 (MTG-S1) and the Copernicus Sentinel-4 mission – have launched on board a SpaceX Falcon 9 from Cape Canaveral in Florida, US.
Both are world-class Earth observation missions developed with European partners to address scientific and societal challenges.
The MTG-S1 satellite will generate a completely new type of data product, especially suited to nowcasting severe weather events, with three-dimensional views of the atmosphere. It is the second in the MTG constellation to be prepared for orbit and is equipped with the first European operational Infrared Sounder instrument.
Copernicus Sentinel-4 will be the first mission to monitor European air quality from geostationary orbit, providing hourly information that will transform how we predict air pollution across Europe, using its ultraviolet, visible, near-infrared light (UVN) spectrometer.

Curiosity Blog, Sols 4586-4587: Straight Drive, Strategic Science
NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on June 28, 2025 — Sol 4583, or Martian day 4,583 of the Mars Science Laboratory mission — at 03:20:22 UTC. NASA/JPL-Caltech Written by Scott VanBommel, Planetary Scientist at Washington University in St. Louis
Earth planning date: Monday, June 30, 2025
Our weekend drive placed Curiosity exactly where we had hoped: on lighter-toned, resistant bedrock we have been eyeing for close study. Curiosity’s workspace tosol did not contain any targets suitable for DRT. After a detailed discussion by the team, weighing science not only in tosol’s plan but the holiday-shifted sols ahead, the decision was made to perform contact science at the current workspace and then drive in the second sol of the plan.
Normally, drives in the second sol of a two-sol plan are uncommon, as we require information on the ground to assess in advance of the next sol’s planning. At present however, the current “Mars time” is quite favorable, enabling Curiosity’s team to operate within “nominal sols” and receive the necessary data in time for Wednesday’s one-sol plan. DAN kicked off the first sol of the plan with a passive measurement, complemented by another in the afternoon and two more on the second sol. Arm activities focused on placing MAHLI and APXS on “La Paz” and “Playa Agua de Luna,” two lighter-toned, laminated rocks.
The rest of the first sol was rounded out with ChemCam LIBS analyses on “La Joya” followed by further LIBS analyses on “La Vega” on the second sol, once Curiosity’s arm was out of the way of the laser. ChemCam and Mastcam additionally imaged “Mishe Mokwa” prior to the nearly straight drive of about 20 meters (about 66 feet). Environmental monitoring activities, imaging of the CheMin inlet cover, and a SAM EBT activity rounded out Curiosity’s efforts on the second sol.
