Video: 00:00:43 Aside from sunlight, the Sun sends out a gusty stream of particles called the solar wind. The ESA-led Solar Orbiter mission is the first to capture on camera this wind flying out from the Sun in a twisting, whirling motion. The solar wind particles spiral outwards as if caught in a cyclone that extends millions of kilometres from the Sun.
Solar wind rains down on Earth's atmosphere constantly, but the intensity of this rain depends on solar activity. More than just a space phenomenon, solar wind can disrupt our telecommunication and navigation systems.
Solar Orbiter is on a mission to uncover the origin of the solar wind. It uses six imaging instruments to watch the Sun from closer than any spacecraft before, complemented by in situ instruments to measure the solar wind that flows past the spacecraft.
This video was recorded by the spacecraft's Metis instrument between 12:18 and 20:17 CEST on 12 October 2022. Metis is a coronagraph: it blocks the direct light coming from the Sun's surface to be able to see the much fainter light scattering from charged gas in its outer atmosphere, the corona.
Metis is currently the only instrument able to see the solar wind's twisting dance. No other imaging instrument can see – with a high enough resolution in both space and time – the Sun's inner corona where this dance takes place. (Soon, however, the coronagraph of ESA's Proba-3 mission might be able to see it too!)
The research paper that features this data, ‘Metis observations of Alfvénic outflows driven by interchange reconnection in a pseudostreamer’ by Paolo Romano et al. was published today in The Astrophysical Journal.
Solar Orbiter is a space mission of international collaboration between ESA and NASA, operated by ESA.
[Technical details: The starting image of the video shows the full view of Solar Orbiter's Metis coronagraph in red, with an image from the spacecraft's Extreme Ultraviolet Imager in the centre (yellow). Zooming to the top left of this view, we see a video derived from Metis observations. The vertical edge of the video spans 1 274 000 km, or 1.83 solar radii. The contrast in the Metis video has been enhanced by using a ‘running difference’ technique: the brightness of each pixel is given by the average pixel brightness of three subsequent frames, minus the average pixel brightness of the three preceding frames. This processing makes background stars appear as horizontal half-dark, half-light lines. Diagonal bright streaks and flashes are caused by light scattering from dust particles close to the coronagraph.]

The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on Nov. 4, 2024, on the company’s 31st commercial resupply services mission for the agency to the International Space Station.Credit: SpaceX Media accreditation is open for the next launch to deliver NASA science investigations, supplies, and equipment to the International Space Station.
NASA and SpaceX are targeting no earlier than Monday, April 21, to launch the SpaceX Dragon spacecraft on the company’s Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. This launch is the 32nd SpaceX commercial resupply services mission to the orbital laboratory for the agency.
Credentialing to cover prelaunch and launch activities is open to U.S. media. The application deadline for U.S. citizens is 11:59 p.m., EDT, Friday, April 4. All accreditation requests must be submitted online at:
https://media.ksc.nasa.gov
Credentialed media will receive a confirmation email after approval. NASA’s media accreditation policy is available online. For questions about accreditation, or to request special logistical support, email: ksc-media-accreditat@mail.nasa.gov. For other questions, please contact NASA Kennedy’s newsroom at: 321-867-2468.
Para obtener información sobre cobertura en español en el Centro Espacial Kennedy o si desea solicitor entrevistas en español, comuníquese con Antonia Jaramillo o Messod Bendayan a: antonia.jaramillobotero@nasa.gov o messod.c.bendayan@nasa.gov.
Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, significantly increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.
Along with food and essential equipment for the crew, Dragon is delivering a variety of experiments, including a demonstration of refined maneuvers for free-floating robots. Dragon also carries an enhanced air quality monitoring system that could protect crew members on exploration missions to the Moon and Mars, and two atomic clocks to examine fundamental physics concepts, such as relativity, and test worldwide synchronization of precision timepieces.
Astronauts have occupied the space station continuously since November 2000. In that time, 283 people from 23 countries have visited the orbital outpost. The space station is a springboard to NASA’s next great leap in exploration, including future missions to the Moon under the Artemis campaign, and human exploration of Mars.

On March 24, 1975, the last in a long line of super successful Saturn rockets rolled out from the vehicle assembly building to Launch Pad 39B at NASA’s Kennedy Space Center in Florida. The Saturn IB rocket for the Apollo-Soyuz Test Project was the 19th in the Saturn class stacked in the assembly building, beginning in 1966 with the Saturn V 500F facilities checkout vehicle. Thirteen flight Saturn V rockets followed, 12 to launch Apollo spacecraft and one to place the Skylab space station into orbit. In addition, workers stacked four flight Saturn IB rockets, three to launch crews to Skylab and one for Apollo-Soyuz, plus another for the Skylab rescue vehicle that was not needed and never launched. Previously, workers stacked Saturn I and Saturn IB rockets on the pads at Launch Complexes 34 and 37. With the successful liftoff in July 1975, the Saturn family of rockets racked up a 100 percent success rate of 32 launches.

NASA Workers in the assembly building prepare to lower the spacecraft onto its Saturn IB rocket.NASA Inspections of the Saturn IB rocket’s first stage fins revealed hairline cracks in several hold-down fittings and managers ordered the replacement of all eight fins. While the cracks would not affect the flight of the rocket they bore the weight of the rocket on the mobile launcher. Workers finished the fin replacement on March 16. Engineers in Kennedy’s spacecraft operations building prepared the Apollo spacecraft for its historic space mission. By early March, they had completed checkout and assembly of the spacecraft and transported it to the assembly building on March 17 to mount it atop the Saturn IB’s second stage. Five days later, they topped off the rocket with the launch escape system.

The next morning, the stack continued its rollout to Launch Pad 39B with the prime crew of Thomas Stafford, Vance Brand, and Donald “Deke” Slayton and support crew members Robert Crippen and Richard Truly on hand to observe. About 7,500 people, including guests, dependents of Kennedy employees and NASA Tours patrons, watched as the stack moved slowly out of the assembly building on its five-mile journey to the launch pad.

NASA On March 20, flight controllers and crews began a series of joint simulations for the joint mission scheduled for July 1975. For the six days of simulations, cosmonauts Aleksei Leonov and Valeri Kubasov and astronauts Stafford, Brand, and Slayton participated in the activity in spacecraft simulators in their respective countries, with both control centers in Houston and outside Moscow fully staffed as if for the actual mission. The exercises simulated various phases of the mission, including the respective launches, rendezvous and docking, crew transfers and joint operations, and undocking.

The astronauts practiced egressing from their spacecraft onto a lift raft and being lifted up with the use of a Billy Pugh rescue net. They practiced wearing their flight coveralls as well as their spacesuits.
