Creativity is critical to making scientific breakthroughs, and art is often an expression (or product) of scientific knowledge. And both art and science begin in the experience of awe, of beholding something grand. The experience of a solar eclipse is a prime example of where these two human endeavors meet.Eclipses are celestial events we can predict with extreme precision, and their occurrence reveals fundamental truths about our place in the universe. Yet, as many eclipse watchers will attest, there is no anticipating how you will feel when experiencing one. The emotional resonance of eclipses is underlined by their presence in artforms in cultures across the world going back millennia.To celebrate the special role of eclipses in connecting art and science, creatives across NASA will be sharing their eclipse-inspired artwork in anticipation of two solar eclipses that will cross the United States on October 14, 2023, and April 8, 2024.The first two pieces in the series are presented below, with short biographies of their creators. || ", "hits": 107 }, { "id": 13450, "url": "https://svs.gsfc.nasa.gov/13450/", "result_type": "Produced Video", "release_date": "2019-12-09T14:00:00-05:00", "title": "Operation IceBridge - P3 on Runway", "description": "4K Wide shot of P3-Orion taxiing on runway.

The reason it hasn’t flown is just because it has taken a while for technology to catch up with the dreams that we had for this amazing mission.[0:23]The coolest thing about my job is just the sheer feeling that this is a 60-year journey that people have gone on to make Parker Solar Probe a reality and to be there at the finish line as we’re on the pad and ready to launch—that is definitely the coolest thing about my job.Betsy Congdon - Lead Thermal Protection Engineer, Johns Hopkins Applied Physics Laboratory[0:51]After working on this for 10 years, it is really a pleasure to see it actually coming to fruition. To be one small part of this huge engineering team that is making science dreams come true is just amazing. I can’t wait to re-write textbooks and change the way we look at the Sun forever. I’m a whole ball of excited, and I honestly don’t know exactly how I’m going to feel at launch but I’m really excited to pass this off to the mission operations team and see all the science data that comes down and just get to enjoy all that Solar Probe brings us.[1:32]There are many enabling technologies, the solar arrays are really important, the autonomy is very important, one of the ones that is obviously also critical is the heat shield, and developing the technology to actually protect the probe at the Sun.[1:49]A sandwich panel is a lot like a honeycomb panel you find in a traditional spacecraft or on airplanes. You have the outer face sheets, and then you have a core. In this case the two outer face sheets are carbon-carbon composite, which is a lot like the graphite epoxy you might find in your golf clubs, it’s just been super-heated, and then the inside is a carbon foam. So the Parker Solar Probe heat shield has a white coating that’s on the Sun-facing surface of this giant frisbee that’s protecting the rest of the spacecraft. And that white coating was specially designed here at the lab, in collaboration with REDD and the space department as well as the Whiting school at Johns Hopkins proper, to actually work at the Sun, specifically designed for Solar Probe. And the concept is basically you’d rather be in a white car on a hot day, than a black car on a hot day—it just knocks down the heat that much more. So it’s helping us stay cool at the Sun.[2:43]The titanium truss was also specially designed for solar probe. It’s a really neat piece. It’s a welded titanium truss that’s about 4 feet tall, but it only weighs about 50 pounds. And the key there is we’re trying to minimize the conduction between the heat shield and the spacecraft, so you want to have as little stuff there as possible.[3:05]But then also the first closest approach will be a very interesting time. We’ll obviously be working towards closest approach a long time and getting science back from the beginning, but the heat shield has to do its hardest work 7 years into the mission, which has always been an interesting construct of the mission.[3:27]When we’re at closest approach, the front surface of the heat shield will be at about 2,500 degrees Fahrenheit. The back surface of the heat shield will be about 600 degrees Fahrenheit. But the spacecraft bus is basically sitting at 85 degrees Fahrenheit. So the shield is actually really keeping everything very cool, most of the stuff is on the bus.[3:50]The mission that is in its current form is actually a solar powered mission, whereas some of the earlier concepts were nuclear powered. So they just had different mission designs, there were different constraints on the mission, and so once this current form iteration with a flat heat shield, or 8-foot frisbee as we like to say, because it’s basically a giant sandwich panel protecting the spacecraft as an umbrella, really developed as a part of this solar-powered mission that is its most recent rendition. And so, reaching out with expertise all around the lab, that whole team really brought this heat shield to fruition.Yanping Guo - Design and Navigation Manager, Johns Hopkins Applied Physics Laboratory[4:34]Of all the space missions I’ve worked on, Parker Solar Probe is the most challenging and complex mission to design and to fly. The launch energy required to reach the Sun is 55 times that required to get to Mars, and two times to Pluto.Annette Dolbow - Integration and Test Lead Engineer, Johns Hopkins Applied Physics Laboratory[5:00]So the tensest moment for me after launch is when we’re sitting in the control room and we’re waiting for that green telemetry to show that the spacecraft is turned on and we can actually talk to it. || 18-03953_PSP_Media_Soundbites_v1.00001_print.jpg (1024x576) [22.0 KB] || 18-03953_PSP_Media_Soundbites_v1.00001_searchweb.png (320x180) [8.9 KB] || 18-03953_PSP_Media_Soundbites_v1.00001_web.png (320x180) [8.9 KB] || 18-03953_PSP_Media_Soundbites_v1.00001_thm.png (80x40) [1.3 KB] || 18-03953_PSP_Media_Soundbites_v1.mp4 (1920x1080) [385.8 MB] || 18-03953_PSP_Media_Soundbites_v1.webm [41.0 MB] || ", "hits": 36 }, { "id": 12993, "url": "https://svs.gsfc.nasa.gov/12993/", "result_type": "Produced Video", "release_date": "2018-07-11T00:00:00-04:00", "title": "Testing Robotic Satellite Servicing Capabilities", "description": "This six-legged, 10 by 16-foot robot mimics how satellites move in space.

Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.Four turboprop engines roar to life under the autumnal Alaskan sun, and we begin to taxi to the main runway of Eielson Air Force Base. After extensive pre-flight configurations, our science payload is primed for our eight-hour mission. Without delay, the engines’ roar becomes a howl as we hurtle down the nearly three-mile stretch of runway until that near-weightless moment we become airborne. Our mission into the clouds of the arctic is underway.Clouds are important drivers of Earth’s climate by regulating the amount of sunlight that is absorbed at the ground versus what is reflected back into space. You’ve probably experienced this firsthand when sitting outside on a hot and sunny summer day when a fluffy cumulus cloud crosses the sky between you and the sun. The respite that you feel from the heat of the sun’s rays means that that energy is no longer reaching you at the surface. At the lower latitudes where most of us live, these thick, stratiform and cumuliform clouds have a cooling effect because the white cloud reflects the sun’s energy back to space instead of being absorbed by the dark brown soil, green trees and plants, or the blue ocean waters. The story is much more complicated at the high latitudes where the frozen ice surface is also very bright white and reflective. Under these conditions, clouds can actually have a net warming effect because they reflect a similar or smaller amount of the incoming sunlight, but also trap more of the outgoing heat radiation and keep it close to the surface (like a blanket.)The exact balance between heating and cooling depends on the cloud properties - droplet number and size - and where the clouds are located in the atmosphere (high or low altitude as well as overlying dark water or bright ice.) Unraveling these effects is important for understanding how the Earth’s radiation balance and climate exist now and how they are likely to change in the future.Differentiating the impacts of low-level clouds versus Arctic sea ice on sunlight from space is hard, because to a passive satellite sensor orbiting many hundreds of kilometers above the Earth’s surface, both the ice and cloud look very similar. To best visualize this system, we must go to the Arctic with scientific research aircraft to measure the cloud properties just below, above, and within the clouds themselves. This was precisely the motivation behind the NASA Arctic Radiation – IceBridge Sea and Ice Experiment (ARISE), which was conducted in the Alaskan Arctic from September-October, 2014.ARISE carried out 14 science flights aboard the NASA Wallops Flight Facility C-130 Hercules aircraft, which was outfitted with a comprehensive suite of scientific instrumentation including a laser altimeter for measuring the sea ice surface properties, in situ cloud probes, and a sun photometer and two radiometers (SSFR, BBR) for measuring the surface, aerosol, and cloud radiative properties. An example 8-hour flight track is shown for the September 7th science flight in the Google Map below. The aircraft was based at Eielson Air Force Base near Fairbanks, AK, and began each flight by transiting approximately 2 hours north to the vicinity of the ice edge in the Beaufort Sea. On the 7th, the aircraft flew a series of parallel, horizontal legs to cover a single satellite grid box of the overflying NASA Clouds and the Earth's Radiant Energy System (CERES) satellite. These measurements help CERES scientists to understand how small-scale variability in ice and cloud extent and properties affect their satellite-based retrievals. Google map showing the flight track of the NASA C-130 aircraft during a research flight conducted on 7 September 2014 north of the Alaskan coast. Before wrapping up the research flight on the 7th and beginning our 2-hour transit back to Fairbanks, we descended into the low-level clouds to measure their microphysical properties with the in situ cloud probes. The video below shows what it’s like to measure an Arctic cloud from inside it! The left side of the video shows the real-time data time series from our research instruments that we are continuously monitoring in flight. The top-right imagery is from the forward-facing camera in the C-130 cockpit.

Snow falls often, and if it melts it is likely to freeze again and add to the accumulation of ice that can date back thousands of millennia. If you can see the ground, it is frozen. If you cannot see the ground, it could be sitting under ice miles thick, like in Antarctica. This is the cryosphere, those regions of Earth from the North and South poles to mountain ranges near the Equator where water is found in solid form. The cryosphere covers many landscapes, but remains dominated by the polar regions. A cover of floating sea ice cracks, shrinks and expands constantly over the Arctic. Sheets of ice cover the bases of mountain ranges and cling to craggy bedrock in Antarctica and Greenland—the two ice sheets alone account for 90 percent of the fresh water on the planet. These regions of the cryosphere are important to scientists because they regulate global climate and are seeing more dramatic climate-driven changes than other regions. The Arctic is warming faster than any spot on Earth while receding and accelerating glaciers in Antarctica and Greenland raise the concern of sea level rise. Watch in the narrated tour below how NASA uses its satellite fleet to observe the remote reaches of the cryosphere. || ", "hits": 53 }, { "id": 10249, "url": "https://svs.gsfc.nasa.gov/10249/", "result_type": "Produced Video", "release_date": "2009-05-14T00:00:00-04:00", "title": "LRO L-14 Press Conference Supporting Videos", "description": "LRO From Launch to OrbitThis video starts with LRO launch animation, shows the spacecraft's path to orbit, and ends with the spacecraft animated over the lunar surface. || LRO_L14_LaunchtoOrbit_50sec_ipod00702_print.jpg (1024x576) [91.7 KB] || LRO_L14_LaunchtoOrbit_50sec_ipod_web.png (320x180) [156.1 KB] || LRO_L14_LaunchtoOrbit_50sec_fullres.webmhd.webm (960x540) [11.4 MB] || LRO_L14_LaunchtoOrbit_50sec_fullres.mov (1280x720) [30.0 MB] || LRO_L14_LaunchtoOrbit_50sec_ipod.m4v (640x360) [8.8 MB] || LRO_L14_LaunchtoOrbit_50sec_svs.mpg (512x288) [7.6 MB] || LRO_L14_LaunchtoOrbit_50sec_portal.wmv (346x260) [7.1 MB] || LRO_L14_LaunchtoOrbit_50sec_fullres.mov.hwshow [218 bytes] || ", "hits": 26 }, { "id": 95, "url": "https://svs.gsfc.nasa.gov/95/", "result_type": "Visualization", "release_date": "1996-05-06T12:00:00-04:00", "title": "Musculoskeletal Modeling Dynamic Simulations: Sitting", "description": "An animation of a skeleton sitting || a000095.00005_web.png (720x480) [387.3 KB] || a000095_thm.png (80x40) [2.5 KB] || a000095_pre.jpg (320x238) [5.4 KB] || a000095_pre_searchweb.jpg (320x180) [27.7 KB] || a000095.webmhd.webm (960x540) [7.8 MB] || a000095.dv (720x480) [130.9 MB] || a000095.mp4 (640x480) [7.5 MB] || a000095.mpg (352x240) [5.1 MB] || ", "hits": 13 } ] }
