NASA, ESA Astronauts Safely Return to Earth

 

SpaceX - Dragon Crew-3 Mission patch.

May 6, 2022

NASA’s SpaceX Crew-3 astronauts aboard the Dragon Endurance spacecraft safely splashed down Friday in the Gulf of Mexico off the coast of Florida, completing the agency’s third long-duration commercial crew mission to the International Space Station. The international crew of four spent 177 days in orbit.

NASA astronauts Kayla Barron, Raja Chari, and Tom Marshburn, and ESA (European Space Agency) astronaut Matthias Maurer returned to Earth in a parachute-assisted splashdown at 12:43 a.m. EDT. Teams aboard SpaceX recovery vessels recovered the spacecraft and astronauts. After returning to shore, the astronauts will fly back to NASA’s Johnson Space Center in Houston.

Crew-3 splashdown

“NASA’s partnership with SpaceX has again empowered us to deliver a crew safely to the space station and back, enabling groundbreaking science that will help our astronauts travel farther out into the cosmos than ever before. This mission is just one more example that we are truly in the golden era of commercial spaceflight,” said NASA Administrator Bill Nelson. “Kayla, Raja, Tom, and Matthias, thank you for your service and welcome home!”

The Crew-3 mission launched Nov. 10 on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. Nearly 24-hours after liftoff, Nov. 11, Endurance docked to the Harmony module’s forward space station port. The astronauts undocked from the same port at 1:05 a.m. May 5, to begin the trip home.

Barron, Chari, Marshburn, and Maurer traveled 75,060,792 miles during their mission, spent 175 days aboard the space station, and completed 2,832 orbits around Earth. Marshburn has logged 339 days in space over his three flights. The Crew-3 mission was the first spaceflight for Barron, Chari, and Maurer.

Throughout their mission, the Crew-3 astronauts contributed to a host of science and maintenance activities and technology demonstrations. In addition, they conducted three spacewalks to perform station maintenance and upgrades outside the space station. This brought the total number of spacewalks for Marshburn to five, while Chari and Barron have each completed two, and Maurer one.

Crew-3 built on previous work investigating how fibers grow in microgravity, used hydroponic and aeroponic techniques to grow plants without soil or other growth material, captured imagery of their retinas as part of an investigation that could detect eye changes of astronauts in space automatically in the future, and performed a demonstration of technology that provides measurements of biological indicators related to disease and infection, among many other scientific investigations. The astronauts took hundreds of photos of Earth as part of the Crew Earth Observation investigation, one of the longest-running investigations aboard the space station, which helps track natural disasters and changes to our home planet.

Crew-3 splashdown

Endurance will return to Florida for inspection and processing at SpaceX’s Dragon Lair, where teams will examine the spacecraft’s data and performance throughout the flight.

The Crew-3 flight is part of NASA’s Commercial Crew Program and its return to Earth follows on the heels of NASA’s SpaceX Crew-4 launch, which docked to the station April 27, beginning another science expedition.

The goal of NASA’s Commercial Crew Program is safe, reliable, and cost-effective transportation to and from the International Space Station. This already has provided additional research time and has increased the opportunity for discovery aboard humanity’s microgravity testbed for exploration, including helping NASA prepare for human exploration of the Moon and Mars.

'Spot the difference' to help reveal Rosetta image secrets

 

ESA - Rosetta Mission patch.

May 5, 2022

Today, ESA and the Zooniverse launch Rosetta Zoo, a citizen science project that invites volunteers to engage in a cosmic game of 'spot the difference'. By browsing through pictures collected by ESA's Rosetta mission, you can help scientists figure out how a comet's surface evolves as it swings around the Sun.

Rosetta Zoo comparison image

Rosetta spent over two years orbiting Comet 67P/Churyumov-Gerasimenko between 2014 and 2016. The spacecraft studied the comet up close, collecting unprecedented data to unlock some of the most intriguing mysteries surrounding the formation and evolution of our Solar System. Partway through Rosetta's studies, the comet approached the Sun – a moment known as 'perihelion'. Following its closest approach of about 186 million km from our star, the comet then moved away again. This meant that its surface was illuminated in different ways during the course of Rosetta’s mission.

Rosetta images of Comet 67P as it approaches perihelion

Rosetta witnessed many landscape changes on Comet 67P: from the impressive fall of cliffs and the formation of pits, to evolving dust patterns and rolling boulders. Scientists are interested in using these changes to investigate the detailed mechanism through which a comet sheds its outer layers, as sunlight heats the ice and dust surrounding the nucleus.

The sheer number of surface changes, however, makes charting them a highly complex task. So scientists are looking for your help.

Vast amounts of data need a vast number of eyes

"The Rosetta archive, which is openly accessible to scientists and the public, contains a vast amount of data collected by this extraordinary mission that have only been partially explored," says Bruno Merín, head of ESA's ESAC Science Data Centre near Madrid, Spain.

"In the past few years, astrophotographers and space enthusiasts have spontaneously identified changes and signs of activity in Rosetta's images. Except for a few cases, though, it has not been possible to link any of these events to surface changes, mostly due to the lack of human eyes sifting through the whole dataset. We definitely need more eyes!"

This is why ESA partnered with the Zooniverse, the world's largest and most popular platform for people-powered research. The new Rosetta Zoo project presents a particular set of data: pairs of images collected by Rosetta's OSIRIS camera showing Comet 67P's surface before and after perihelion.

Volunteers are invited to view images of roughly the same region side by side and identify a variety of changes, from large-scale dust transport to comet chunks that moved or even vanished. Sometimes this may require zooming in or out a few times, or rotating the images to spot changes on different scales, getting up close and personal with the iconic comet.

"Given the complexity of the imagery, the human eye is much better at detecting small changes between images than automated algorithms are," explains Sandor Kruk, a postdoctoral researcher at the Max Planck Institute for Extraterrestrial Physics near Munich, Germany, who first conceived and initiated the project during his ESA research fellowship a couple of years ago.

"The OSIRIS images have been publicly available in the archives for some time, but many images have not been analysed yet for changes in the surface of the comet. That is why we decided to set up this citizen science project and ask volunteers to inspect Rosetta images of 67P. Given the excitement Rosetta generated during its mission, we hope this project will be joined by many members of the public to help scientists analyse the data it generated."

Your responses will improve our understanding of the Solar System

Thanks to the visual inspection of many volunteers, the project will produce maps of changes and active areas on the comet's surface, with labels for each type of change. Scientists will then be able to associate the activity of the comet with modifications on its surface, developing new models to link the physics of comet activity to observed changes such as lifted boulders or collapsed cliffs.

2014 vs. 2016

By digging through Rosetta's images and playing a cosmic game of 'spot the difference', you will help us reach new heights in our understanding of comets and the Solar System as a whole. But the benefits go both ways: we hope that by opening up this data to the public, we are improving the openness of our work, increasing citizen engagement in scientific research, and building stronger connections between science and society.

Anybody can use Rosetta Zoo online for free, without needing to sign up, install an app or programme, or have any previous scientific experience. Spot the differences between as many or as few image pairs as you have time for – whether that’s five minutes whilst waiting for the bus, or regular evenings of cometary exploration.

"What does a primitive comet look like? No one knows, but with the help of volunteers we can characterise how comets evolve now and understand the physics driving those changes: then we will be able to rewind the movie of cometary evolution all the way back to the origin of the Solar System," comments planetary scientist Jean-Baptiste Vincent from the DLR Institute of Planetary Research in Berlin, Germany.

The Station Changes Command as Crew-3 Prepares to Depart

 

ISS - Expedition 67 Mission patch.

May 4, 2022

NASA astronaut Tom Marshburn handed over command of the International Space Station to Russian cosmonaut Oleg Artemyev in a traditional Change of Command ceremony which began at 2:35 p.m. EDT today. Artemyev, a veteran of three spaceflights to the space station, will lead the Expedition 67 crew until the end of summer.

Marshburn and his Crew-3 crewmates Kayla Barron, Raja Chari, and ESA astronaut Matthias Maurer have been living aboard the orbital lab since November 11, 2021, and are set to depart tonight. Hatch closure is set for 11:20 p.m. EDT, with undocking following at 1:05 a.m. EDT. The commercial crew quartet is due to splashdown off the coast of Florida  at 12:43 a.m. EDT on Friday, May 6. Watch live on NASA TV, the agency’s website, and the app.

The Crew-3 astronauts worked on final Dragon cargo operations and configuring Dragon for departure, final egress, and hatch closure, as well as transferring emergency hardware from Dragon to the space station prior to departure. The Endurance crew closed out research operations which included transferring and packing frozen samples and ice bricks from the Minus Eighty (Degrees Celsius) Laboratory Freezer for ISS (MELFI) into coldbags in preparation for the return to Earth. MELFI provides the space station storage and fast-freezing of life science and biological samples. The Crew-3 astronauts also removed and stowed their Actiwatches, small, lightweight, wrist-worn devices that simultaneously detect body movement and light intensity. They are used to evaluate sleep-wake adaptation and circadian cycle and determine if space travel has an impact on the sleep-wake patterns of crewmembers.

The station’s four newest astronauts, Kjell Lindgren, Bob Hines, Jessica Watkins, and Samantha Cristoforetti, had a light duty day performing some life science, lab maintenance, and inventory tasks. The foursome and their three Russian crewmates are due to have an off-duty day following the departure of the SpaceX Crew-3 mission.

In the station’s Russian segment, Artemyev and Flight Engineers Sergey Korsakov and Denis Matveev performed monthly maintenance checks on laptops and video equipment, as well as physical training, and a robotic piloting experiment.

CAPSTONE Charts a New Path for NASA's Moon-Orbiting Space Station

 

NASA - CAPSTONE Mission patch.

May 4, 2022

It will have equilibrium. Poise. Balance. This pathfinding CubeSat will practically be able to kick back and rest in a gravitational sweet spot in space – where the pull of gravity from Earth and the Moon interact to allow for a nearly-stable orbit – allowing physics to do most of the work of keeping it in orbit around the Moon.

Sounds like a heavenly work-life balance, right? Funnily enough – the orbit is formally known in orbital mechanics as a "near rectilinear halo orbit" (NRHO). Which means, if you were able to trace the shape of the orbit, it would look like an elongated oval with sides so long they're nearly straight.

The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) CubeSat owned and operated by Advanced Space in Westminster, Colorado, will be the first spacecraft to test this orbit. Researchers want to show the orbit requires less fuel and allows constant direct communications contact with Earth as the spacecraft passes by the Moon.

And NASA has big plans for this unique type of orbit. Engineers expect it will allow them to park bigger spacecraft – including the lunar-orbiting space station Gateway – in orbit around the Moon for about 15 years.

About six days after launch, CAPSTONE will deploy from the Rocket Lab Photon spacecraft bus and begin its four-month transfer to its NRHO, firing its thrusters to power its journey. After a couple of additional "clean-up" maneuvers, and a critical maneuver that will insert the spacecraft into the NRHO, the spacecraft will occasionally and sparingly fire its thrusters to stay on course, allowing NASA to understand the orbit dynamics for at least six months.

"CAPSTONE will be precisely controlled and maintained and will benefit tremendously from the nearly-stable physics of its near rectilinear halo orbit," said Elwood Agasid, deputy program manager of Small Spacecraft Technology at NASA's Ames Research Center in California's Silicon Valley. "The burns will be timed to give the spacecraft an extra boost as it naturally builds momentum – this requires a lot less fuel than a more circular orbit would require."

If viewed from Earth, CAPSTONE's orbit would repeatedly trace a consistent oval around the Moon as the spacecraft moves from the lunar North Pole to the lunar South Pole. It will take nearly a week to complete a full lunar orbit. While it's over the South Pole, the spacecraft will be traveling at its slowest and farthest away from the lunar surface – approximately 47,000 miles (76,000 kilometers) above the Moon. Then, as it builds momentum, the spacecraft will travel at its fastest and closest height above the Moon and cross over the North Pole, at only approximately 2,100 miles (3,400 kilometers) high.

"This orbit has an added bonus of allowing Gateway to have optimal communications with future Artemis missions operating on the lunar surface as well as back to Earth," said Agasid. "This could unlock new opportunities for future lunar science and exploration efforts."

New NASA Black Hole Sonifications with a Remix

 

NASA - Chandra X-ray Observatory patch.

May 4, 2022

Data Sonification: Black Hole at the Center of the Perseus Galaxy Cluster (X-ray)

Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster’s hot gas that could be translated into a note – one that humans cannot hear some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound machine. This new sonification – that is, the translation of astronomical data into sound – is being released for NASA’s Black Hole Week this year.

In some ways, this sonification is unlike any other done before (1, 2, 3, 4) because it revisits the actual sound waves discovered in data from NASA's Chandra X-ray Observatory. The popular misconception that there is no sound in space originates with the fact that most of space is essentially a vacuum, providing no medium for sound waves to propagate through. A galaxy cluster, on the other hand, has copious amounts of gas that envelop the hundreds or even thousands of galaxies within it, providing a medium for the sound waves to travel.

In this new sonification of Perseus, the sound waves astronomers previously identified were extracted and made audible for the first time. The sound waves were extracted in radial directions, that is, outwards from the center. The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency. (A quadrillion is 1,000,000,000,000,000.) The radar-like scan around the image allows you to hear waves emitted in different directions. In the visual image of these data, blue and purple both show X-ray data captured by Chandra.

Data Sonification: Black Hole at the Center of Galaxy M87 (Multiwavelength)

In addition to the Perseus galaxy cluster, a new sonification of another famous black hole is being released. Studied by scientists for decades, the black hole in Messier 87, or M87, gained celebrity status in science after the first release from the Event Horizon Telescope (EHT) project in 2019. This new sonification does not feature the EHT data, but rather looks at data from other telescopes that observed M87 on much wider scales at roughly the same time. The image in visual form contains three panels that are, from top to bottom, X-rays from Chandra, optical light from NASA’s Hubble Space Telescope, and radio waves from the Atacama Large Millimeter Array in Chile. The brightest region on the left of the image is where the black hole is found, and the structure to the upper right is a jet produced by the black hole. The jet is produced by material falling onto the black hole. The sonification scans across the three-tiered image from left to right, with each wavelength mapped to a different range of audible tones. Radio waves are mapped to the lowest tones, optical data to medium tones, and X-rays detected by Chandra to the highest tones. The brightest part of the image corresponds to the loudest portion of the sonification, which is where astronomers find the 6.5-billion solar mass black hole that EHT imaged.

Chandra X-ray Observatory

More sonifications of astronomical data, as well as additional information on the process, can be found at the “A Universe of Sound” website: https://chandra.si.edu/sound/

These sonifications were led by the Chandra X-ray Center (CXC) and included as part of NASA's Universe of Learning (UoL) program with additional support from NASA’s Hubble Space Telescope/Goddard Space Flight Center. The collaboration was driven by visualization scientist Kimberly Arcand (CXC), astrophysicist Matt Russo, and musician Andrew Santaguida (both of the SYSTEMS Sound project). NASA's Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science from Cambridge Massachusetts and flight operations from Burlington, Massachusetts. NASA's Universe of Learning materials are based upon work supported by NASA under cooperative agreement award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and the Jet Propulsion Laboratory.
