California, Oct 31 (Canadian-Media): A new discovery was made by a group of collaborators from around the world including University of California (CN), San Diego's Alison Coil, and Rhodes College's David Rupke by exploring the influence of galactic winds from a distant galaxy called Makani, phys.org reports said.

Their study's findings were published in Nature and provided, for the first time direct evidence of the role of galactic winds—ejections of gas from galaxies—in creating the circumgalactic medium (CGM). The unique composition of Makani—meaning wind in Hawaiian—uniquely lent itself to the breakthrough findings.
The study indicated that the hourglass shape of Makani's nebula is strongly reminiscent of similar galactic winds in other galaxies, but that Makani's wind is much larger than in other observed galaxies.
"This means that we can confirm it's actually moving gas from the galaxy into the circumgalactic regions around it, as well as sweeping up more gas from its surroundings as it moves out," Rupke explained. "And it's moving a lot of it—at least one to 10 percent of the visible mass of the entire galaxy—at very high speeds, thousands of kilometers per second..."Makani's existence provides one of the first direct windows into how a galaxy contributes to the ongoing formation and chemical enrichment of its CGM."

NASA will broadcast the departure of a Japanese cargo spacecraft from the International Space Station beginning at 1 p.m. EDT Friday, Nov. 1, on NASA Television and the agency’s website.
Ground controllers will use the station’s Canadarm2 robotic arm to detach the Japan Aerospace Exploration Agency’s H-II Transport Vehicle-8 (HTV-8) several hours before its release. Expedition 61 Flight Engineers Christina Koch and Jessica Meir of NASA will take over the controls of the robotic arm to release the spacecraft at 1:20 p.m.
HTV-8 delivered more than four tons of scientific experiments, including an upgrade to the Cell Biology Experiment Facility (CBEF-L), a small-sized satellite optical communication system (SOLISS), and a payload for testing the effects of gravity on powder and granular material (Hourglass). The spaceship also delivered supplies and new lithium-ion batteries for an upgrade from the nickel-hydrogen batteries that store power generated by the station’s solar arrays.
The cargo craft spent five weeks attached to the orbiting laboratory following a Sept. 24 launch from the Tanegashima Space Center in Japan. It will be loaded with trash and the nickel-hydrogen batteries removed from the station over a series of recent spacewalks.
Following its departure from the space station, HTV-8 will be commanded to deorbit on Saturday, Nov. 2, and burn up harmlessly in the Earth’s atmosphere. The deorbit will not air on NASA TV.

Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, physical sciences, Earth and space science. Advances in these areas will help to keep astronauts healthy during long-duration space travel and demonstrate technologies for future human and robotic exploration beyond low-Earth orbit to the Moon and Mars. Space station research through the ISS National Lab also provides opportunities for other U.S. government agencies, private industry, and academic and research institutions, to conduct microgravity research that leads to new technologies, medical treatments, and products that improve life on Earth.
Highlights of space station research that will be facilitated by research aboard this SpaceX Dragon mission include testing the effectiveness of a device to separate and capture water droplets suspended in an air stream, delivering a next-generation spaceborne system to image Earth in higher spectral resolution than currently possible onboard the TERRA satellite, and testing conditions to develop an inexpensive and scalable process to manufacture optical materials in space.
Cargo resupply from U.S. companies ensures a national capability to deliver critical science research to the space station, significantly increasing NASA's ability to conduct new investigations at the only laboratory in space. This is the 19th SpaceX mission under NASA’s Commercial Resupply Services contract.
The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and enables research not possible on Earth. The space station has been occupied continuously since November 2000. In that time, 239 people and a variety of international and commercial spacecraft have visited the orbiting laboratory. The space station remains the springboard to NASA's next great leap in exploration, including future missions to the Moon and eventually to Mars.

SpaceX was founded in 2002 by Elon Musk, a major contractor for NASA, to help reduce space transportation costs with an ultimate goal of helping colonize Mars.
Although Musk hoped to have the capsule delivered to NASA by the end of the year, he stressed that safety was paramount.
"If everything goes according to plan, it would be in the first quarter of next year," Bridenstine said of the launch. "But remember—and this is the important thing that we have to get right on messaging—there are still things that we can learn or could learn that could be challenging that we have to resolve.
"I'm not saying that's going to happen, I don't know. That's why we test."

"It's a pretty arduous engineering job to get the parachutes right," Musk said.
"Parachutes, they look easy but they are definitely not easy," he added. "We want to get at least something on the order of 10 successful tests in a row before launching astronauts."
After retiring its space shuttle program, NASA had been relying on Russia to ferry astronauts to and from the space station at a cost of $85 million a seat. It is now counting on SpaceX and Boeing to carry out that task.
The first manned flight to the space station was due to take place last year but SpaceX suffered a major setback in April when its Crew Dragon spacecraft exploded during testing, prompting delays and renewed tests.
"You know, honestly, if there's a test program and nothing happens in that test program, I would say that test program is insufficiently rigorous," Musk said Thursday.
"Space is hard," he added.
