NASA 747SP Reg: N747NA another highlight from my US trip, airside at NASA hangar and ramp at Palmdale.
Originally a US Air Force RB-57, N927NA was converted to WB-57F for high altitude research. NASA brought the jet to California to observe the return of the Orion spacecraft from the Artemis mission (...and it MAY have taken part in a hypersonic missile test flight).
For 122 Pictures in 2022 #77 "Playing cards", this is a poker deck with images licensed from NASA, mostly from the Hubble Telescope. Each value has its own image, with each suite card of that value having the same (all 2s have the same image, etc). I do like the back of the cards with a design taken from 1930s science fiction rockets (at least that's what they remind me of). I would have added poker chips to the image, but mine disappeared in our last move.

A winter storm that moved through the Mid-Atlantic on Feb. 16 and 17, 2015 extended the northeastern U.S. snowcover farther south. Until this storm hit, southern New Jersey and southeastern Pennsylvania appeared snow-free on satellite imagery from the previous week.
The overnight storm blanketed the entire states of New Jersey and Pennsylvania, as seen on this Feb. 16 image. The image was taken from the MODIS or Moderate Resolution Imaging Spectroradiometer instrument that flies aboard NASA's Terra satellite. The snow cover from the storm actually extended even farther south than the image. Snowfall also blanketed West Virginia, Kentucky, Maryland, Delaware and Virginia, while freezing rain and icy conditions affected the Carolinas, Tennessee and Georgia.
On Feb. 17, 2015, NOAA's National Weather Service noted "The winter storm that brought widespread snow, sleet and freezing rain to parts of the south-central U.S. and Mid-Atlantic will wind down as it moves offshore Tuesday. Lingering snow and freezing rain is possible early Tuesday for parts of the Northeast and mid-Atlantic, with rain across parts of the Southeast."

NASA's Andromeda Fighter was designed as a defensive and offensive space fighter that could be launched from earth and return on it's own power. The craft was also designed to be launched in groups of 4 not unlike the traditional Space Shuttle. The Andromeda is manned by a crew of 3 and it's weapon systems include guided rockets which launch from the port and starboard pods as well as 30mm rocket cannon.
This was done for Tromas's Real World Starfighter Contest.
What could cause a huge cylindrical mountain to rise from the surface of Venus? Such features that occur on Venus are known as coronas. Pictured here in the foreground is 500-kilometer wide Atete Corona found in a region of Venus known as the Galindo. The featured image was created by combining multiple radar maps of the region to form a computer-generated three-dimensional perspective. The series of dark rectangles that cross the image from top to bottom were created by the imaging procedure and are not real. The origin of massive coronas remains a topic of research although speculation holds they result from volcanism. Studying Venusian coronas help scientists better understand the inner structure of both Venus and Earth. via NASA ift.tt/2e9hMOr

A swirling Eastern Pacific Ocean storm system headed for California was spotted by NOAA's GOES-West satellite on February 28. According to the National Weather Service, this storm system has the potential to bring heavy rainfall to the drought-stricken state.
The storm was captured using visible data from NOAA's GOES-West or GOES-15 satellite on Feb. 28 at 1915 UTC/11:15 a.m. PST was made into an image by NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. The storm's center appeared as a tight swirl, with bands of clouds and showers already sweeping over the state extending from northern California to Baja California, Mexico.
At 11:30 a.m. PST on February 28, Bill Patzert, climatologist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. said, "Right now from northern to southern California we are being battered by very heavy rain, strong winds and our coastal communities are being battered by high surf. Through the weekend we are bracing for mud and rock slides in areas that recently burned [from wildfires]. Flooding is looming up and down the state."
The National Weather Service (NWS) serving Los Angeles posted a Flood Watch for the region on Friday, February 28. The Flood Watch notes the "potential for flash flooding and debris flows for some 2013 and 2014 burn areas in Los Angeles County from this morning through Saturday evening (March 1).”
The NWS Flood Watch also noted "a very strong and dynamic storm will bring a significant amount of rain to much of southwestern California through Saturday evening. A flash flood watch has been issued for several recent burn areas in Los Angeles County due to the abundant rainfall expected. Rain rates at times are expected to range from a half inch to one inch per hour which could cause significant mud and debris flows. There will be a chance of thunderstorms with locally higher rainfall rates."
"Californians haven't seen rain and wind this powerful in 3 years," Patzert said. "By early next week, as this system moves east, this powerful system will wreak havoc causing snow and ice storms through the Midwest into the Northeast."
GOES satellites provide the kind of continuous monitoring necessary for intensive data analysis. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on Earth's surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms and hurricanes.
On a positive note, Patzert noted, "This is a nice down payment on drought recovery in the parched Western U.S."

NASA's Hubble Space Telescope has captured an image of an unusual edge-on galaxy, revealing remarkable details of its warped dusty disk and showing how colliding galaxies spawn the formation of new generations of stars.
The dust and spiral arms of normal spiral galaxies, like our own Milky Way, appear flat when viewed edge-on. This month's Hubble Heritage image of ESO 510-G13 shows a galaxy that, by contrast, has an unusual twisted disk structure, first seen in ground-based photographs obtained at the European Southern Observatory (ESO) in Chile. ESO 510-G13 lies in the southern constellation Hydra, roughly 150 million light-years from Earth.
Details of the structure of ESO 510-G13 are visible because the interstellar dust clouds that trace its disk are silhouetted from behind by light from the galaxy's bright, smooth central bulge.

Webb is clearing up a space mystery!
Early in our cosmic history, gas in the universe shifted — over hundreds of millions of years — from opaque to transparent. Only when the gas became clear did light travel freely through the cosmos. But how did this change happen? Webb proves the answer lies in galaxies from the early universe.
Astronomers looked into galaxies so far away that their light took almost 13 billion years to reach us. That made these galaxies the perfect window into what the universe was like about 900 million years after the big bang, just before it became fully transparent.
Webb witnessed these galaxies heating up and ionizing the gas around them, turning their surrounding regions transparent. These transparent “bubbles” were about 2 million light-years in radius! Scientists believe the bubbles of transparency eventually grew and merged, creating a transparent universe. Learn more: www.nasa.gov/feature/goddard/2023/nasa-s-webb-proves-gala...

Image description: More than 20,000 tiny galaxies appear across the black background of space. The galaxy colors vary. Some of the smallest galaxies are shades of orange and pink. Most galaxies are so distant they appear as single points of light. Slightly larger, fuzzier galaxies appear whiter. Some have distinct spiral arms. In front of the galaxies are several foreground stars, though none appear larger than the largest galaxies. The foreground stars are scattered around the image, appear blue and have eight prominent diffraction spikes. At the center is a pink object with six diffraction spikes. This is quasar J0100+2802. It appears slightly smaller than the blue foreground stars.

On Jan. 20 at 2:30 p.m. EST the VIIRS instrument aboard NASA-NOAA's Suomi NPP captured this image of the winter storm moving through the central U.S.
Credits: NASA Goddard Rapid Response
The low pressure area from the Eastern Pacific Ocean moved into the western U.S. and tracked across the four corners region into Texas where NASA-NOAA's Suomi NPP satellite observed the clouds associated with the storm. The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP satellite captured the visible image on January 20, 2016 at 19:30 UTC (2:30 p.m. EST) when the storm was over the central U.S. In the image, snow cover is visible in the Rockies and southern Great Lakes states.
VIIRS collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.
That low pressure system located over the south central United States on Jan. 21 is expected to track east across the Tennessee Valley and will give way to a deepening coastal low pressure area. The National Weather Service said "This latter feature takes over and becomes a dominant force in setting up heavy snow bands over the Mid-Atlantic and very gusty winds."
The storm system is expected to bring an increased risk of severe weather from far southeastern Texas across southern Louisiana/Mississippi, and into the far western Florida Panhandle on Thursday, Jan. 21. That threat for severe weather will move east as the low pressure area continues heading in that direction.
The National Weather Service Weather Prediction Center in College Park, Maryland said "A potentially crippling winter storm is anticipated for portions of the mid-Atlantic Friday into early Saturday. Snowfall may approach two feet for some locations, including the Baltimore and Washington, D.C. metro areas. Farther north, there is uncertainty in snowfall for the New York City-to-Boston corridor. Farther south, significant icing is likely for portions of Kentucky and North Carolina."

February 17, 2012: Astronomers using NASA's Hubble Space Telescope may have found evidence for a cluster of young, blue stars encircling HLX-1, one of the first intermediate-mass black holes ever discovered. Astronomers believe the black hole may once have been at the core of a now-disintegrated dwarf galaxy. The discovery of the black hole and the possible star cluster has important implications for understanding the evolution of supermassive black holes and galaxies

NASA 926, a WB-57, returns to March ARB from a dress rehearsal for the Artemis II splash down in the Pacific Ocean.
Red and white vapor clouds filled the skies over the Marshall Islands as part of NASA’s Equatorial Vortex Experiment (EVEX). The red cloud was formed by the release of lithium vapor and the white tracer clouds were formed by the release of trimethyl aluminum (TMA). These clouds allowed scientists on the ground from various locations in the Marshall Islands to observe the neutral winds in the ionosphere.

The Equatorial Vortex Experiment (EVEX) was successfully conducted during the early morning hours (eastern time) May 7 from Roi Namur, Republic of the Marshall Islands. A NASA Terrier-Oriole sounding rocket was launched at 3:39 a.m. EDT and was followed by a launch of Terrier-Improved Malemute sounding rocket 90 seconds later. Preliminary indications are that both rockets released their vapor clouds of lithium or trimethyl aluminum, which were observed from various locations in the area, and all science instruments on the rockets worked as planned. More information on EVEX can be found at www.nasa.gov/mission_pages/sounding-rockets/news/evex.html
These were the second and third rockets of four planned for launch during this year’s campaign in the Marshall Islands. The first and fourth rockets are supporting the Metal Oxide Space Cloud experiment (MOSC), which is studying radio frequency propagation.

NASA's Goddard Space Flight Center in Greenbelt, Maryland, played a critical role in the test flight of the #Orion spacecraft on Dec. 5, 2014. Goddard's Networks Integration Center, pictured here, coordinated the communications support for both the Orion vehicle and the Delta IV rocket, ensuring complete communications coverage through NASA's Space Network and Tracking and Data Relay Satellite.
The Orion spacecraft lifted off from Cape Canaveral Air Force Station's Space Launch Complex 37 in Florida at 7:05 a.m. EST. The Orion capsule splashed down about four and a half hours later, at 11:29 a.m. EST, about 600 miles off the coast of San Diego, California. While no humans were aboard Orion for this test flight, in the future, Orion will allow humans to travel deeper into space than ever before, including an asteroid and Mars.

If you climbed to the top of this 13th century stone tower, it looks like you could reach out and touch the North Celestial Pole, the point at the center of all the star trail arcs. The well-composed image with scattered meteor streaks was recorded over a period of five and half hours as a series of 45 second long exposures spanning the dark of the night on July 7/8. The exposures were made with a digital camera fixed to a tripod near Marathon, Greece, planet Earth. Of course, the graceful star trails reflect the Earth's daily rotation around its axis. By extension, the axis of rotation leads to the center of the concentric arcs in the night sky. Convenient for northern hemisphere night sky photographers and celestial navigators alike, the bright star Polaris is very close to the North Celestial Pole and so makes the short bright trail in the tower's central gap. via NASA ift.tt/2aii6rS
Just 15 minutes after its closest approach to Pluto on July 14, 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon. The smooth expanse of the informally named icy plain Sputnik Planum (right) is flanked to the west (left) by rugged mountains up to 11,000 feet (3,500 meters) high, including the informally named Norgay Montes in the foreground and Hillary Montes on the skyline. To the right, east of Sputnik, rougher terrain is cut by apparent glaciers. The backlighting highlights over a dozen layers of haze in Pluto’s tenuous but distended atmosphere. The image was taken from a distance of 11,000 miles (18,000 kilometers) to Pluto; the scene is 780 miles (1,250 kilometers) wide.
