NASA's Space to Ground: Shipping and Receiving

NASA's Space to Ground: Shipping and Receiving

Week of February 25, 2022: NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station (ISS). 

This is Northrop Grumman’s 17th contracted resupply mission under the second Commercial Resupply Services contract with NASA. NASA astronaut Raja Chari commanded the Canadarm2 robotic arm to capture the U.S. Cygnus cargo craft. Robotics controllers on the ground took over shortly afterwards and remotely guided the Canadarm2 with Cygnus attached and installed it to the Unity module to begin three months of cargo operations. 

Cygnus launched atop an Antares rocket at 12:40 p.m. EST Saturday, Feb. 19, 2022, from NASA’s Wallops Flight Facility in Virginia. At about 4:44 a.m., NASA astronaut Raja Chari, along with NASA astronaut Kayla Barron as backup, captured Cygnus, carrying 8,300 pounds of research, hardware, and science experiments to the International Space Station.

Each Cygnus spacecraft is named in honor of an individual who has made great contributions to human spaceflight. For the NG-17 mission, Cygnus celebrates Piers Sellers, a former NASA astronaut and renowned climate scientist.

Cygnus will remain at the International Space Station until May 2022 before it deploys CubeSats, then disposes of several thousand pounds of trash during its re-entry into Earth’s atmosphere, which will result in its destruction.

The International Space Station Program’s greatest accomplishment is as much a human achievement as it is a technological one—how best to plan, coordinate, and monitor the varied activities of the Program’s many organizations.

An international partnership of space agencies provides and operates the elements of the ISS. The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken.

Clair de Lune by Debussy | Artemis Music

Clair de Lune by Debussy | Artemis Music

This special rendition of Debussy's Clair de Lune (‘Moonlight’), commissioned by Artemis Music LLC and performed by internationally renowned pianist Wing-Chong Kam, was beamed into space and orbited the Earth aboard the International Space Station on July 28th, 2021, in commemoration of the timeless beauty of Claude Debussy's masterpiece and in celebration of the unity of music for all humankind. Visualizations of the Moon courtesy of the NASA Scientific Visualizations Studio, with digital 3D data captured by NASA’s Lunar Reconnaissance Orbiter (LRO).

The cosmic perspective of space inspires a cognitive shift in humans. Debussy’s Clair de Lune perhaps comes as close as possible to stirring the emotions of awe and wonder experienced by space travelers. 

The universe is full of music, and we humans are learning how to use music to not only understand the science of the universe, but to grasp our place in it.

“Music is what happens in the space between the notes.”

- Claude Debussy

Curiosity's View From the Top of the 'Greenheugh Pediment'

​Stitched together from 28 images, this view from NASA's Curiosity Mars rover was captured on April 9, 2020, the 2,729th Martian day, or sol, of the mission after the rover ascended a steep slope, part of a geologic feature called "Greenheugh Pediment." In the foreground is the crusty sandstone cap that stretches the length of the pediment, forming an overhanging ledge in some parts. At center is the "clay-bearing unit," a region with a unique story to tell about the history of water on Mount Sharp, the 3-mile-tall (5-kilometer-tall) mountain Curiosity has been ascending since 2014. In the distance at the top of the image is the floor of Gale Crater, which is 96 miles (154 kilometers) wide.

The rover's Mast Camera, or Mastcam, provided the panorama. Malin Space Science Systems in San Diego built and operates Mastcam. A division of Caltech, NASA's Jet Propulsion Laboratory in Southern California built the Curiosity rover and manages the Mars Science Laboratory mission for the agency's Science Mission Directorate in Washington.

The panorama has been white-balanced so that the colors of the rock materials resemble how they would appear under daytime lighting conditions on Earth.

Martian Winds at Work | ESA Mars Express

Martian Winds at Work | ESA Mars Express

These images from the European Space Agency's Mars Express orbiter shows part of possibly the largest single source of dust on Mars: a wind-sculpted feature known as the Medusae Fossae Formation, or MFF.

The MFF is not only a veritable dust factory, but also remarkably extensive—it is the largest sedimentary deposit on the planet and stretches out discontinuously for more than 5,000 km, covering an area about the size of India. It is named for the Greek mythological Gorgon Medusa, who was able to turn those who looked into her eyes to stone, with the suffix ‘fossae’ being Latin for trenches or hollows.

The formation is found along the boundary between Mars’ southern highlands and northern lowlands (known as the martian dichotomy), and sits between the planet’s two most prominent volcanic regions (Tharsis and Elysium). It also contains the Eumenides Dorsum mountain range, the edges of which can be seen in the gentle elevation extending out of the bottom right of the frame (northeast).

Wind is a powerful sculptor on the Red Planet—as well as here on Earth. Mars Express has spied several other landscapes on Mars that have been significantly shaped by wind, such as Nili Fossae, Arabia Terra, Syrtis Major, southern dunes, and Schiaparelli crater.

In fact, this region likely formed as a result of wind moving material around on Mars’ surface. The MFF is thought to consist of ash released by the volcanoes in the nearby Tharsis region—including Olympus Mons, the largest volcano in the Solar System—that has been deposited either through the air or via fast-moving ‘pyroclastic’ flows of lava, gas and rocky debris.

The crescent-shaped depressions are also the doing of martian winds. These saucer- or trough-shaped hollows, known as blowouts, are apparently carved into the sand by wind erosion. To create a blowout, sand-laden wind whips along and erodes the smooth surface until it hits an obstacle—a buried object such as a rock or more resistant patch of sediment, for example. The wind is then forced around and beneath the object, creating an eddy, before finally heading back upwards, lifting sand with it as it goes.

Wind erosion is thought to be the latest stage of erosional processes acting on the MFF. This is evidenced by the general lack of craters seen on the formation’s surface; if wind erosion had occurred long ago only, we would expect to see more recent craters atop the wind-sculpted terrain. Overall, the fact that only a few craters are visible here, sitting alongside underlying older rock that has subsequently been covered and draped in dust, implies that the region’s surface is young.

Exploring the surface features and geology of Mars is a key objective of Mars Express. Launched in 2003, the spacecraft has been orbiting the Red Planet for nearly two decades; it has since been joined by the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO), which arrived in 2016, while the ExoMars Rosalind Franklin rover and its accompanying surface science platform are scheduled for launch in 2022. Together, this fleet of martian explorers is working towards a fuller understanding of Mars and its intriguing landscapes.

NASA’s James Webb Space Telescope: Exploring the TRAPPIST-1 System

NASA’s James Webb Space Telescope: Exploring the TRAPPIST-1 System

During its first operating cycle, the James Webb Space Telescope will set its sights on the TRAPPIST-1 system, an incredible collection of seven rocky exoplanets 41 light years away from Earth.

Astrobiologists, like Dr. Giada Arney from NASA's Goddard Space Flight Center, are excited about this system because TRAPPIST-1 is a perfect laboratory for studying habitability! It consists of seven rocky planets, distributed across the system’s habitable zone, or the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets. Webb will characterize the atmospheres of these planets and help scientists learn more about planetary formation and habitability.

NASA ScienceCasts: The International Space Station's New Solar Arrays

NASA ScienceCasts: The International Space Station's New Solar Arrays

The new ISS Roll Out Solar Arrays (iROSA) being installed on the International Space Station are providing power to the station with improved efficiency. ROSA technology will also help power the NASA Lunar Gateway outpost, and the DART mission as it makes its way to the Didymos asteroid system.

These solar arrays  are lightweight, flexible power sources for spacecraft designed and developed by Redwire. Redwire Corporation is an American aerospace manufacturer and space infrastructure technology company headquartered in Jacksonville, Florida.

This new type of solar array provides much more energy than traditional solar arrays at much less mass. Traditional solar panels used to power satellites are bulky, with heavy panels folded together using mechanical hinges. Given a space-bound payload is limited in its mass and volume by necessity, ROSA is 20 percent lighter (with a mass of 325 kg (717 lb)) and one-fourth the volume of rigid panel arrays with the same performance.

ROSA is a flexible and rollable solar array that operates the same way a measuring tape unwinds on its spool. The new solar array design rolls up to form a compact cylinder for launch with significantly less mass and volume, potentially offering substantial cost savings as well as an increase in power for satellites. 

ROSA has a center wing made of a flexible material which support the strings of photovoltaic cells that produce electricity. Both the sides of the wing have a narrow arm that extends through the length of the wing to provide support to the array, called a high strain composite boom. The booms look like split tubes made of a stiff composite material, flattened and rolled up lengthwise. 

The array does not need any motor to unfurl. This is achieved using the potential energy stored in the booms that is released as each boom transitions from a coil shape to a straight support arm. The solar wings are then deployed due to strain energy in rolled booms that are present at the two ends of the structure.

Solar Orbiter Captures Giant Solar Eruption | ESA/NASA

Solar Orbiter Captures Giant Solar Eruption | ESA/NASA

The Full Sun Imager of the Extreme Ultraviolet Imager on board the European Space Agency/NASA Solar Orbiter spacecraft captured a giant solar eruption on February 15, 2022.

Solar prominences are large structures made of tangled magnetic field lines that keep dense concentrations of solar plasma suspended above the Sun’s surface and often take the form of arching loops.

This is the largest solar prominence eruption ever observed in a single image together with the full solar disc. They are often associated with coronal mass ejections, which if directed towards Earth, can wreak havoc with our technology and everyday lives.

This coronal mass ejection was not directed at Earth. In fact, it was traveling away from us.

Smoky Ring for a Halo | Hubble

Smoky Ring for a Halo | Hubble

Two stars shine through the center of a ring of cascading dust in this image taken by the NASA/European Space Agency Hubble Space Telescope. The star system is named DI Cha, and while only two stars are apparent, it is actually a quadruple system containing two sets of binary stars.

As this is a relatively young star system it is surrounded by dust. The young stars are moulding the dust into a wispy wrap.

The host of this alluring interaction between dust and star is the Chamaeleon I dark cloud—one of three such clouds that comprise a large star-forming region known as the Chamaeleon Complex. DI Cha's juvenility is not remarkable within this region. In fact, the entire system is among not only the youngest but also the closest collections of newly formed stars to be found and so provides an ideal target for studies of star formation.

Hubble Captures a Peculiar Galactic Pair

Hubble Captures a Peculiar Galactic Pair

This striking image from the NASA/European Space Agency (ESA) Hubble Space Telescope showcases Arp 298, a stunning pair of interacting galaxies. Arp 298—which comprises the two galaxies NGC 7469 and IC 5283—lies roughly 200 million light-years from Earth in the constellation Pegasus. The larger of the two galaxies pictured here is the barred spiral galaxy NGC 7469, and IC 5283 is its diminutive companion. NGC 7469 is also host to an active, supermassive black hole and a bright ring of star clusters.

The “Arp” in this galaxy pair’s name signifies that they are listed in the Atlas of Peculiar Galaxies compiled by the astronomer Halton Arp. The Atlas of Peculiar Galaxies is a rogues’ gallery of weird and wonderful galaxies containing peculiar structures, featuring galaxies exhibiting everything from segmented spiral arms to concentric rings. This interacting galaxy pair is a familiar sight for Hubble—a portrait of the merging galaxies in Arp 298 was published in 2008.

This image of Arp 298 contains data from three separate Hubble proposals. By combining observations from three proposals, Arp 298 is captured in glorious detail in seven different filters from two of Hubble’s instruments—the Wide Field Camera 3 and the Advanced Camera for Surveys.

The process of planning Hubble observations starts with a proposal—a detailed plan of what an astronomer intends to observe and their scientific motivation for doing so. Once a year, these proposals are gathered and judged in a gruelling review process which assess their scientific merit and feasibility. Fewer than 20% of the proposed observations in any given year will make it through this process and be approved, which makes observing time with Hubble highly prized indeed.
