“A mind of limits, a camera of thoughts” is the name of this contribution from citizen scientist Prateek Sarpal. Jupiter inspires artists and scientists with its beauty. In this image, south is up, and the enhanced color evokes an exotic marble and childhood joy.
The original image was captured by JunoCam, the camera on NASA’s Juno mission in orbit around Jupiter. This image was taken on Juno’s 22nd close pass by Jupiter on Sept. 12, 2019.
A huge payoff from the longevity of the LRO mission is the repeat coverage obtained by the LROC Wide Angle Camera (WAC). The WAC has a very wide field-of-view (FOV), 90° in monochrome mode and 60° in multispectral mode, hence its name. On the one hand, the wide FOV enables orbit-to-orbit stereo, which allowed LROC team members at the DLR to create the unprecedented 100 meter scale near-global (0° to 360° longitude and 80°S to 80°N latitude) topographic map of the Moon (the GLD100)!
As humanity continues to excel in going beyond human abilities through technology, the victory comes with a price: American photographer Roland Miller travels to abandoned places once found useful by the space exploration organization NASA and the U.S. Army and collects their remnants as memories.
There was a time when even NASA didn’t know if humans could eat in the microgravity environment of space. Thankfully for the future of long-term crewed missions, John Glenn proved that it was indeed possible when he ate applesauce from an aluminum tube while orbiting the Earth in 1962.
Since then, the research conducted at our Space Food Systems Laboratory at Johnson Space Center has resulted in improved taste, variety and packaging of foods intended for space travel. Current-day astronauts are now given a standard menu of over 200 approved food and drink items months before launch, allowing them to plan their daily meals far in advance.
So, with such a variety of foods to choose from, what does the typical astronaut eat in a day? Here is an example from the International Space Station standard menu:
Sounds tasty, right?
However, these are only suggestions for astronauts, so they still have some choice over what they ultimately eat. Many astronauts, including Tim Kopra, combine different ingredients for meals.
Others plan to eat special foods for the holidays. Astronauts Scott Kelly and Kjell Lindgren did just that on Thanksgiving last year when they ate smoked turkey, candied yams, corn and potatoes au gratin.
Another key factor that influences what astronauts eat is the availability of fresh fruits and vegetables, which are delivered via resupply spacecrafts. When these foods arrive to the space station, they must be eaten quickly before they spoil. Astronaut Tim Peake doesn’t seem to mind.
Nutrition is important to help counteract some of the effects spaceflight have on the body, such as bone and muscle loss, cardiovascular degradation, impairment of immune function, neurovestibular changes and vision changes.
“Nutrition is vital to the mission,” Scott M. Smith, Ph.D., manager for NASA’s Nutritional Biochemistry Lab said. “Without proper nutrition for the astronauts, the mission will fail. It’s that simple.”
We work hard to help astronauts feel less homesick by providing them with food that not only reminds them of life back on Earth, but is also nutritious and healthy.
Here are some unusual space food inventions that are no longer in use:
10 Images to Celebrate the Historic Exploration of the Pluto System
One year ago, our New Horizons mission made history by exploring Pluto and its moons – giving humankind our first close-up look at this fascinating world on the frontier of our solar system.
Since those amazing days in July 2015, the New Horizons spacecraft has transmitted numerous images and many other kinds of data home for scientists and the public alike to study, analyze, and just plain
love. From Pluto’s iconic “heart” and sweeping ice-mountain vistas to its flowing glaciers and dramatic blue skies, it’s hard to pick just one favorite picture. So the mission team has picked 10 – and in no special order, placed them here.
Click the titles for more information about each image. You’ve seen nine of them before, and the team added a 10th favorite, also sure to become one of New Horizons’ “greatest hits.”
In the northern region of Pluto’s Sputnik Planum, swirl-shaped patterns of light and dark suggest that a surface layer of exotic ices has flowed around obstacles and into depressions, much like glaciers on Earth.
This dramatic image from our New Horizons spacecraft shows the dark, rugged highlands known as Krun Macula (lower right), which border a section of Pluto’s icy plains.
Pluto’s haze layer shows its blue color in this picture taken by the New Horizons Ralph/Multispectral Visible Imaging Camera (MVIC). The high-altitude haze is thought to be similar in nature to that seen at Saturn’s moon Titan.
At half the diameter of Pluto, Charon is the largest satellite relative to its planet in the solar system. Many New Horizons scientists expected Charon to be a monotonous, crater-battered world; instead, they’re finding a landscape covered with mountains, canyons, landslides, surface-color variations and more.
Our 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 backlighting highlights over a dozen layers of haze in Pluto’s tenuous but distended atmosphere.
The color and brightness of both Pluto and Charon have been processed identically to allow direct comparison of their surface properties, and to highlight the similarity between Charon’s polar red terrain and Pluto’s equatorial red terrain. Pluto and Charon are shown with approximately correct relative sizes, but their true separation is not to scale.
A moment’s study reveals surface features that appear to be texturally ‘snakeskin’-like, owing to their north-south oriented scaly raised relief. A digital elevation model created by the New Horizons’ geology shows that these bladed structures have typical relief of about 550 yards (500 meters). Their relative spacing of about 3-5 kilometers makes them some of the steepest features seen on Pluto.
This view is dominated by the large, bright feature informally named the “heart,” which measures approximately 1,000 miles (1,600 kilometers) across. The heart borders darker equatorial terrains, and the mottled terrain to its east (right) are complex. However, even at this resolution, much of the heart’s interior appears remarkably featureless—possibly a sign of ongoing geologic processes.
One of Pluto’s most identifiable features, Cthulhu (pronounced kuh-THU-lu) stretches nearly halfway around Pluto’s equator, starting from the west of the great nitrogen ice plains known as Sputnik Planum. Measuring approximately 1,850 miles (3,000 kilometers) long and 450 miles (750 kilometers) wide, Cthulhu is a bit larger than the state of Alaska.
Colorful Composition Maps of Pluto
The powerful instruments on New Horizons not only gave scientists insight on what Pluto looked like, their data also confirmed (or, in many cases, dispelled) their ideas of what Pluto was made of. These compositional maps – assembled using data from the Linear Etalon Imaging Spectral Array (LEISA) component of the Ralph instrument – indicate the regions rich in ices of methane (CH4), nitrogen (N2) and carbon monoxide (CO), and, of course, water ice (H2O).
Scientists have long known that Jupiter is noisy: The planet produces intense radio storms powered by interactions between the planet and its moons, not to mention the wild gases at play on the planet itself. But they didn’t realize that Juno’s entry into Jupiter’s orbit would produce such complex data. “While this transition from the solar wind into the magnetosphere was predicted to occur at some point in time,” the agency writes in the blog post, “the structure of the boundary between those two regions proved to be unexpectedly complex, with different instruments reporting unusual signatures both before and after the nominal crossing.”
A NASA-led team of scientists has developed the first-ever method for detecting the presence of different types of underground forest fungi from space, information that may help researchers predict how climate change will alter forest habitats.
“EPIC maintains a constant view of the fully illuminated Earth as it rotates, providing scientific observations of ozone, vegetation, cloud height and aerosols in the atmosphere. Once EPIC begins regular observations next month, the camera will provide a series of Earth images allowing study of daily variations over the entire globe. About twice a year the camera will capture the moon and Earth together as the orbit of DSCOVR crosses the orbital plane of the moon.”
A trip to Mars, with its invisible technology and vast, unprecedented distance from home, could estrange or alienate a crew to an unprecedented degree. Such a distance could produce an entirely new kind of boredom, impossible to imagine on Earth.
The Lunar Plant Growth Habitat team, a group of NASA scientists, contractors, students and volunteers, is finally bringing to life an idea that has been discussed and debated for decades. They will try to grow arabidopsis, basil, sunflowers, and turnips in coffee-can-sized aluminum cylinders that will serve as plant habitats. But these are no ordinary containers – they’re packed to the brim with cameras, sensors, and electronics that will allow the team to receive image broadcasts of the plants as they grow. These habitats will have to be able to successfully regulate their own temperature, water intake, and power supply in order to brave the harsh lunar climate.
That’s the sort of hard-headedness that I used to love about NASA - the idea that humans, if they just kept plugging away, could figure stuff out - and that other humans - astronauts and test pilots - would stake their very lives on it. Not this hand-wringing by deniers that argue we can’t figure anything out, we can’t afford to do anything, it’s all a vast hoax, and we shouldn’t try. A far cry from the can-do of NASA. How could guys that once put their very lives in the hands of science be so dumb about it as they get old?
