Space weather describes the changing environment throughout the Solar System, driven by the energetic and unpredictable nature of our Sun. Solar wind, solar flares and Coronal Mass Ejections can result in geomagetic storms on Earth, potentially damaging satellites in space and the technologies that rely on them, as well as infrastructure on the ground. ESA's future Lagrange mission will keep constant watch on the Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure. ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.

The sun is the very centerpiece of our solar system and the most important source of energy for life on Earth. And according to MNN, it's on the verge of receiving a visitor. On Oct. 29, NASA's Parker Solar Probe achieved a milestone by becoming the closest man-made object to the sun. Over the next several years, the probe will orbit closer to the sun with the closest approach being 3.83 million miles away. The mission was launched to study some of the sun's biggest secrets. https://www.mnn.com/earth-matters/space/blogs/nasa-mission-solar-probe-plus-explore-sun-outer-atmosphere http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

September live mini course

On Sept. 22, 2006,the Japanese Aerospace Exploration Agency launched a sun-observing satellite called Hinode, or Solar-B. It was named after the Japanese word for "sunrise." The satellite orbits about 400 miles above the Earth in a sun-synchronous orbit, which means it's always facing the sun. Since it launched, it's been measuring the sun's magnetic fields and taking cool photos of solar flares, sunspots and transits across the sun.

Following years of work and preparation, a United Launch Alliance Delta IV Heavy rocket launched NASA's Parker Solar Probe for an unprecedented mission to "kiss the Sun." The spacecraft aims to unravel 60 years' worth of mysteries surrounding the Sun’s corona and how it effects life on Earth. Learn more at: http://www.nasa.gov/parkersolarprobe

Watch in 360 degrees as a United Launch Alliance Delta IV Heavy rocket lifts off from Space Launch Complex-37 at Cape Canaveral Air Force Station in Florida carrying NASA's Parker Solar Probe. Roughly the size of a small car, the spacecraft lifted off at 3:31 a.m. EDT on Aug. 12, 2018, starting its historic mission to the Sun.

The Ulysses mission revolutionized our understanding of the sun, but it's been the only orbiter to take this kind of out-of-ecliptic journey. Will an upcoming mission give us even more?

NASA launches its Parker Solar Probe to explore the sun's atmosphere.

NASA’s Parker Solar Probe mission launched Aug. 11 from Cape Canaveral Air Force Station in Florida. The mission will be the first to fly directly through the Sun’s corona – the hazardous region of intense heat and solar radiation in the Sun’s atmosphere that is visible during an eclipse. It will gather data that could help answer questions about solar physics that have puzzled scientists for decades. Gathering information about fundamental processes near the Sun can help improve our understanding of how our solar system’s star changes the space environment, where space weather can affect astronauts, interfere with satellite orbits, or damage spacecraft electronics. This video is available for download from NASA's Image and Video Library: https://images.nasa.gov/details-NHQ_2018_0812_Parker%20Solar%20Probe%20Mission%20Launches%20to%20Touch%20the%20Sun%20-.html

The Parker Solar Probe will be the first-ever mission to "touch" the Sun, traveling directly into the Sun's atmosphere about 4 million miles from the surface. Read the story: https://go.nasa.gov/2KEExYZ NASA launch schedule: https://go.nasa.gov/2JfklMB The Sun contains 99.8 of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny Mercury to the gas giants to the Oort Cloud, 186 billion miles away. But even though the Sun has such a powerful pull, it's surprisingly hard to actually go to the Sun: It takes 55 times more energy to go to the Sun than it does to go to Mars. Why is it so difficult? The answer lies in the same fact that keeps Earth from plunging into the Sun: Our planet is traveling very fast - about 67,000 miles per hour - almost entirely sideways relative to the Sun. The only way to get to the Sun is to cancel that sideways motion. Since Parker Solar Probe will skim through the Sun's atmosphere, it only needs to drop 53,000 miles per hour of sideways motion to reach its destination, but that's no easy feat. In addition to using a powerful rocket, the Delta IV Heavy, Parker Solar Probe will perform seven Venus gravity assists over its seven-year mission to shed sideways speed into Venus' well of orbital energy. These gravity assists will draw Parker Solar Probe's orbit closer to the Sun for a record approach of just 3.83 million miles from the Sun's visible surface on the final orbits. Though it's shedding sideways speed to get closer to the Sun, Parker Solar Probe will pick up overall speed, bolstered by Sun's extreme gravity - so it will also break the record for the fastest-ever human-made objects, clocking in at 430,000 miles per hour on its final orbits.

In this video, we look at the Solar Parker Probe in detail. First by understanding who Dr. Parker was, and what he theorized about Solar Winds. Then we go into how the probe will make it to the Sun, using multiple gravity assists of Venus. After that, we discuss the Corona of the Sun, and how the probe will be able to survive the high-temperature environment with it’s innovative and autonomous design. Then we look at the different instrument onboard, and what they will be able to tell us about solar winds.

Ashes to Ashes, Dust to Dust: The Fate of Stars Like the Sun Greg Sloan of the Space Telescope Science Institute Our Sun, though seemingly eternal, is about halfway through its roughly 10-billion-year lifespan. What will happen when the Sun dies? Not only will the answer be important to whoever inhabits Earth in a few billion years, it is important to astronomers today. Quiet stars like the Sun are many times more numerous than large stars and play a major role in how galaxies develop. Importantly, how these stars die determines when life can first form in the galaxy. Host: Dr. Frank Summers Recorded live on Tuesday, August 7 at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A. More information: http://hubble.stsci.edu/about_us/public_talks/

In In this video. we look at NASA's Parker Solar Probe, which is expected to Launch later this week. We discuss why this mission is important, how it will help scientists understand Solar Winds, and what we will be able to do with that information.

The Sun launches another stealthy solar storm this week, but its so wispy and moving so slowly it might not cause much of a disturbance. Aurora photographers at high latitudes might enjoy sporadic views but mid-latitudes might miss out. Amateur radio operators and emergency responders get a nice boost in radio propagation this week as a bright region rotates into view with another coming in a few days. GPS users at low and mid-latitudes should enjoy decent reception, while those at high latitudes might get a few disruptions on the night side near aurora.

Something mysterious is going on at the Sun. In defiance of all logic, its atmosphere gets much, much hotter the farther it stretches from the Sun’s blazing surface. Temperatures in the corona — the Sun’s outer atmosphere — spike to 3 million degrees Fahrenheit, while just 1,000 miles below, the underlying surface simmers at a balmy 10,000 F. How the Sun manages this feat is a mystery that dates back nearly 150 years, and remains one of the greatest unanswered questions in astrophysics. Scientists call it the coronal heating problem. Watch the video to learn how astronomers first discovered evidence for this mystery during an eclipse in the 1800s, and what scientists today think could explain it.

NASA's Parker Solar Probe will explore the sun's atmosphere wearing a nearly 5-inch coat of carbon-composite solar shields. According to CNN, the mission is expected to launch in early August. This is NASA's first mission to the sun and its outermost atmosphere. It's not a mission that any human can make, so NASA is sending a roughly 10-foot-high probe on the historic mission. The probe will be closer to the sun than any spacecraft has ever reached before. https://www.cnn.com/2018/07/20/us/nasa-parker-solar-probe/index.html http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

Space Weather jumps into action this week with two weak solar storms en route to Earth. NASA models predict they will hit starting July 9 and they could easily bring aurora to high latitudes, if not mid-latitudes. Amateur radio operators are also in for some fun as a new region rotates into view and brings with it a boost in solar flux, which will help radio propagation just in time for hurricane season. GPS users shouldn't be affected by the low-level flaring of this region on Earth's day side, but should stay vigilant near aurora and near the dawn-dusk terminators for glitches in their reception. Low-latitude GPS/GNSS reception might even improve under the influence of these weak solar storms. See details of the coming storms, when this new active region will be in view, catch up on aurora photos, and see what else is in store!

Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

Johns Hopkins APL's Rosanna Smith and Gordon Maahs discuss what makes Parker Solar Probe's solar arrays so special, and how they will operate both close to and far from our star. Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

UC Berkeley's Stuart Bale, principal investigator for the FIELDS instrument suite, talks with Johns Hopkins APL's Jennifer Fischer about how FIELDS will measure electric and magnetic fields and waves around the Sun. Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

Evan Smith, fault management test lead, and Sanae Kubota, fault management lead engineer - both of Johns Hopkins APL - discuss how Parker Solar Probe's team ensures the spacecraft can protect itself while on its historic mission to the Sun. This includes simulations of potential issues that could possible arise during the mission to make sure the team and the spacecraft are ready for launch.

The FIELDS antennae are a critical part of Parker Solar Probe's science operations. They need to be stowed alongside the spacecraft during launch, and released for deployment when safely in space. Johns Hopkins APL's Jennifer Fischer, Randy Schlotterbeck, and Sarah Bucior explain and perform a test of the release mechanism, known as "clam shells." Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

Parker Solar Probe's launch vehicle - the Delta IV Heavy, the most powerful rocket currently used by NASA - will carry the spacecraft into space later this year, marking the first time the Delta IV Heavy will carry a NASA science mission aloft. Johns Hopkins APL's Jennifer Fischer, deputy system assurance lead, interviews Project Manager Andy Driesman about the launch and the efforts to date to make this historic mission possible. Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

How do you design the trajectory of a mission to the touch the sun? Johns Hopkins APL's Yanping Guo, mission design and navigation manager, explains how the alignment of the planets led to the creation of the best route for NASA's Parker Solar Probe. Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

Nick Pinkine, Parker Solar Probe mission operations manager, explains how the team at the Johns Hopkins Applied Physics Laboratory prepares to operate the spacecraft by performing complex mission simulations while still on the ground. Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

Even though Parker Solar Probe's thermal protection system (TPS) will shield the spacecraft from the tremendous heat of the Sun as the mission flies through the corona, the integration and testing team still needs to ensure the probe will perform as expected. Johns Hopkins APL's Rosanna Smith and Elizabeth Abel explain how the Parker Solar Probe team uses the space environment simulator at NASA's Goddard Space Flight Center to test the spacecraft. Learn more: https://www.nasa.gov/content/goddard/parker-solar-probe http://parkersolarprobe.jhuapl.edu/

The Parker Solar Probe team needs to get the spacecraft into a deep cold environment, just like it will experience while in space. Johns Hopkins APL's Felipe Ruiz and Andy Webb describe how the thermal vacuum chamber at NASA's Goddard Space Flight Center creates the intense cold temps - and there's a humorous exaggeration in the explanation that true science-fiction-comedy film fans will catch!

ESO's La Silla Observatory will be enveloped in darkness by a total solar eclipse on 2 July 2019. This rare event may result in a number of bright stars and planets becoming briefly visible in the sky. As shown in this artist's impression, planets Venus and Mercury along with the bright stars Sirius, Procyon, Rigel and Betelgeuse are those which may be visible during the 2019 La Silla eclipse.

The first video shows an active region on the Sun (with an inset Earth, for size reference) taken in extreme ultraviolet, or EUV, light by the Solar Dynamics Observatory. The EVE sounding rocket supports the calibration of EUV measurements taken by spacecraft to make sure the data they provide are accurate. With the usual focus on satellite-based solar imagery, one often forgets about the important contributions of ground-based observatories. Here we present a video of imagery collected at the Big Bear Solar Observatory (BBSO) site of the National Solar Observatory (NSO). The light from the Sun is passed through a filter that admits light from the hydrogen alpha spectral line (6562.8 angstroms or 656.28 nanometers) in the red region of the spectrum. This reveals many details which cannot be seen in our usual broad-spectrum view of the Sun, particularly filaments across the solar disk and limb. Ground-based observatories are subjected to a number of challenges different from their space-based counterparts, including gaps in the visibility of their target (i.e. nighttime), clouds (some slightly visible in this movie) and atmospheric turbulence (also some visible here). The spectral line for hydrogen alpha is a deep red and rather dark for regular digital displays. For this visualization, we have used a brighter 'blackbody' colour table to improve visibility.
