Video: 00:00:40 Back in 2023, we reported on Solar Orbiter’s discovery of tiny jets near the Sun’s south pole that could be powering the solar wind. The team behind this research has now used even more data from the European Space Agency’s prolific solar mission to confirm that these jets exist all over dark patches in the Sun’s atmosphere, and that they really are a source of not only fast but also slow solar wind.
The newfound jets can be seen in this sped-up video as hair-like wisps that flash very briefly, for example within the circled regions of the Sun's surface. In reality they last around one minute and fling out charged particles at about 100 km/s.
The surprising result is published today in Astronomy & Astrophysics, highlighting how Solar Orbiter’s unique combination of instruments can unveil the mysteries of the star at the centre of our Solar System.
The solar wind is the never-ending rain of electrically charged particles given out by the Sun. It pervades the Solar System and its effects can be felt on Earth. Yet despite decades of study, its origin remained poorly understood. Until now.
The solar wind comes in two main forms: fast and slow. We have known for decades that the fast solar wind comes from the direction of dark patches in the Sun’s atmosphere called coronal holes – regions where the Sun’s magnetic field does not turn back down into the Sun but rather stretches deep into the Solar System.
Charged particles can flow along these ‘open’ magnetic field lines, heading away from the Sun, and creating the solar wind. But a big question remained: how do these particles get launched from the Sun in the first place?
Building upon their previous discovery, the research team (led by Lakshmi Pradeep Chitta at the Max Planck Institute for Solar System Research, Germany) used Solar Orbiter’s onboard ‘cameras’ to spot more tiny jets within coronal holes close to the Sun’s equator.
By combining these high-resolution images with direct measurements of solar wind particles and the Sun’s magnetic field around Solar Orbiter, the researchers could directly connect the solar wind measured at the spacecraft back to those exact same jets.
What’s more, the team was surprised to find not just fast solar wind coming from these jets, but also slow solar wind. This is the first time that we can say for sure that at least some of the slow solar wind also comes from tiny jets in coronal holes – until now, the origin of the solar wind had been elusive.
The fact that the same underlying process drives both fast and slow solar wind comes as a surprise. The discovery is only possible thanks to Solar Orbiter’s unique combination of advanced imaging systems, as well as its instruments that can directly detect particles and magnetic fields.
The measurements were taken when Solar Orbiter made close approaches to the Sun in October 2022 and April 2023. These close approaches happen roughly twice a year; during the next ones, the researchers hope to collect more data to better understand how these tiny jets ‘launch’ the solar wind.
Solar Orbiter is a space mission of international collaboration between ESA and NASA, operated by ESA. This research used data from Solar Orbiter’s Extreme Ultraviolet Imager (EUI), Polarimetric and Helioseismic Imager (PHI), Solar Wind Plasma Analyser (SWA) and Magnetometer (MAG). Find out more about the instruments Solar Orbiter is using to reveal more about the Sun.

Firefly Aerospace’s Blue Ghost lander getting encapsulated in SpaceX’s rocket fairing ahead of the planned liftoff for 1:11 a.m. EST Jan. 15 from Launch Complex 39A at NASA’s Kennedy Space Center in FloridaSpaceX As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the agency is preparing to fly ten instruments aboard Firefly Aerospace’s first delivery to the Moon. These science payloads and technology demonstrations will help advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions on the Moon and beyond, for the benefit of all.
Firefly’s lunar lander, named Blue Ghost, is scheduled to launch on a SpaceX Falcon 9 rocket Wednesday, Jan.15, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. After a 45-day cruise phase, Blue Ghost is targeted to land near a volcanic feature called Mons Latreille within Mare Crisium, a basin approximately 340 miles wide (550 kilometers) located in the northeast quadrant of the Moon’s near side.
How can we enable more precise navigation on the Moon? How do spacecraft interact with the lunar surface? How does Earth’s magnetic field influence the effects of space weather on our home planet? NASA’s instruments on this flight will conduct first-of-their-kind demonstrations to help answer these questions and more, including testing regolith sampling technologies, lunar subsurface drilling capabilities, increasing precision of positioning and navigation abilities, testing radiation tolerant computing, and learning how to mitigate lunar dust during lunar landings.
The ten NASA payloads aboard Firefly’s Blue Ghost lander include:
Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) will measure heat flow from the Moon’s interior by measuring the thermal gradient, or changes in temperature at various depths, and thermal conductivity, or the subsurface material’s ability to let heat pass through it. LISTER will take several measurements up to 10 feet deep using pneumatic drilling technology with a custom heat flow needle instrument at its tip. Data from LISTER will help scientists retrace the Moon’s thermal history and understand how it formed and cooled. Lead organization: Texas Tech University
Lunar PlanetVac (LPV) is designed to collect regolith samples from the lunar surface using a burst of compressed gas to drive the regolith into a sample chamber (sieving) for collection and analysis by various instruments. Additional instrumentation will then transmit the results back to Earth. The LPV payload is designed to help increase the science return from planetary missions by testing low-cost technologies for collecting regolith samples in-situ. Lead organization: Honeybee Robotics
Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon by reflecting very short laser pulses from Earth-based Lunar Laser Ranging Observatories. The laser pulse transit time to the Moon and back is used to determine the distance. Data from NGLR could improve the accuracy of our lunar coordinate system and contribute to our understanding of the inner structure of the Moon and fundamental physics questions. Lead organization: University of Maryland
Regolith Adherence Characterization (RAC) will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. RAC will measure accumulation rates of lunar regolith on surfaces (for example, solar cells, optical systems, coatings, and sensors) through imaging to determine their ability to repel or shed lunar dust. The data captured will help test, improve, and protect spacecraft, spacesuits, and habitats from abrasive regolith. Lead organization: Aegis Aerospace
Radiation Tolerant Computer (RadPC) will demonstrate a computer that can recover from faults caused by ionizing radiation. Several RadPC prototypes have been tested aboard the International Space Station and Earth-orbiting satellites, but this flight will provide the biggest trial yet by demonstrating the computer’s ability to withstand space radiation as it passes through Earth’s radiation belts, while in transit to the Moon, and on the lunar surface. Lead organization: Montana State University
Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move and prevent hazardous lunar dust accumulation on surfaces. EDS is designed to lift, transport, and remove particles from surfaces with no moving parts. Multiple tests will demonstrate the feasibility of the self-cleaning glasses and thermal radiator surfaces on the Moon. In the event the surfaces do not receive dust during landing, EDS has the capability to re-dust itself using the same technology. Lead organization: NASA’s Kennedy Space Center
Lunar Environment heliospheric X-ray Imager (LEXI) will capture a series of X-ray images to study the interaction of solar wind and Earth’s magnetic field that drives geomagnetic disturbances and storms. Deployed and operated on the lunar surface, this instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact Earth. Lead organizations: Boston University, NASA’s Goddard Space Flight Center, and Johns Hopkins University
Lunar Magnetotelluric Sounder (LMS) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed. Lead organization: Southwest Research Institute
Lunar GNSS Receiver Experiment (LuGRE) will demonstrate the possibility of acquiring and tracking signals from GNSS (Global Navigation Satellite System) constellations, specifically GPS and Galileo, during transit to the Moon, during lunar orbit, and on the lunar surface. If successful, LuGRE will be the first pathfinder for future lunar spacecraft to use existing Earth-based navigation constellations to autonomously and accurately estimate their position, velocity, and time. Lead organizations: NASA Goddard, Italian Space Agency
Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) will use stereo imaging photogrammetry to capture the impact of the rocket exhaust plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion, which is an important task as bigger, heavier spacecraft and hardware are delivered to the Moon in close proximity to each other. This instrument also flew on Intuitive Machines’ first CLPS delivery. Lead organization: NASA’s Langley Research Center
Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A Boeing 777-300ER aircraft is being inspected by one of Near Earth Autonomy’s drones Feb. 2, 2024, at an Emirates Airlines facility in Dubai, United Arab Emirates.Near Earth Autonomy A small business called Near Earth Autonomy developed a time-saving solution using drones for pre-flight checks of commercial airliners through a NASA Small Business Innovation Research (SBIR) program and a partnership with The Boeing Company.
Before commercial airliners are deemed safe to fly before each trip, a pre-flight inspection must be completed. This process can take up to four hours, and can involve workers climbing around the plane to check for any issues, which can sometimes result in safety mishaps as well as diagnosis errors.
With NASA and Boeing funding to bolster commercial readiness, Near Earth Autonomy developed a drone-enabled solution, under their business unit Proxim, that can fly around a commercial airliner and gather inspection data in less than 30 minutes. The drone can autonomously fly around an aircraft to complete the inspection by following a computer-programmed task card based on the Federal Aviation Administration’s rules for commercial aircraft inspection. The card shows the flight path the drone’s software needs to take, enabling aircraft workers with a new tool to increase safety and efficiency.
“NASA has worked with Near Earth Autonomy on autonomous inspection challenges in multiple domains,” says Danette Allen, NASA senior leader for autonomous systems.
“We are excited to see this technology spin out to industry to increase efficiencies, safety, and accuracy of the aircraft inspection process for overall public benefit.”
The photos collected from the drone are shared and analyzed remotely, which allows experts in the airline maintenance field to support repair decisions faster from any location. New images can be compared to old images to look for cracks, popped rivets, leaks, and other common issues.
The user can ask the system to create alerts if an area needs to be inspected again or fails an inspection. Near Earth Autonomy estimates that using drones for aircraft inspection can save the airline industry an average of $10,000 per hour of lost earnings during unplanned time on the ground.
Over the last six years, Near Earth Autonomy completed several rounds of test flights with their drone system on Boeing aircraft used by American Airlines and Emirates Airlines.
NASA’s Small Business Innovation Research / Small Business Technology Transfer program, managed by the agency’s Space Technology Mission Directorate, aims to bolster American ingenuity by supporting innovative ideas put forth by small businesses to fulfill NASA and industry needs. These research needs are described in annual SBIR solicitations and target technologies that have significant potential for successful commercialization.
Small business concerns with 500 or fewer employees, or small businesses partnering with a non-profit research institution such as a university or a research laboratory can apply to participate in the NASA SBIR/STTR program.

The ongoing mystery surrounding recent drone sightings has become increasingly complex, with conflicting reports making it difficult to draw definitive conclusions. However, a new and intriguing element has emerged alongside these drones sightings: numerous accounts of mysterious orbs, potentially of alien origin, flying at both low and high altitudes.
Reports of mysterious orbs have been increasing in recent weeks. These orbs have been sighted at both high altitudes and closer to urban areas.

Pilots have reported encounters to air traffic control. Listen to conversations between pilots and traffic control.
And a passenger aboard United Airlines flight UA2359 from Chicago to Newark recently captured footage of these mysterious orbs. The video, shared online by the user “EasilyAmusedEE” on December 16, 2024, shows objects at altitudes between 40,000 and 50,000 feet—far beyond the capabilities of consumer drones. The footage was reportedly taken using an iPhone 16 Pro Max.
Video plane passenger films unknown orbs.
About the drone sightings: Meanwhile, eyewitness accounts describe these so-called drones as crafts that emit no noise, suggesting advanced technology. Additionally, there are claims that these crafts seem to intentionally draw attention, as they have reportedly interfered with cars (lamps flickering), electronics, streetlights (lamps flickering), and even fully charged batteries, which are said to be instantly drained in their presence.
Video shows among other (drone/orb) sightings, cars lamps flickering, streetlights lamps flickering, fully charged batteries drained.
This surge in Orb sightings raises more questions. Are these orbs extraterrestrial in origin? Could they be deliberately associated with the drone phenomena, or is their timing coincidental? Some suggest the possibility of a false flag operation, hinting at a deeper and potentially misleading agenda by the U.S. government.
Whether these drones and Orbs sightings point to advanced human technology, extraterrestrial activity, or a mix of both, one thing is clear: there is something significant going on.View the full article
