Hubble Spies a Diminutive Galaxy

A relatively small, oval-shaped galaxy, tilted diagonally. Its center glows brightly and dims gradually to its edge. Its center also holds a few small, blue, glowing spots where stars are forming and dark wisps of dust that cross the galaxy. The image has a black background on which many background galaxies and foreground stars are visible.
This NASA/ESA Hubble Space Telescope image reveals the dwarf elliptical galaxy named IC 3430.

This NASA/ESA Hubble Space Telescope image reveals the subtle glow of the galaxy named IC 3430, located 45 million light-years from Earth in the constellation Virgo. This dwarf elliptical galaxy is part of the Virgo cluster, a rich collection of galaxies both large and small, many of which are very similar in type to this diminutive galaxy.

Like its larger elliptical cousins, IC 3430 has a smooth, oval shape lacking any recognizable features like arms or bars, and is missing much of the gas needed to form many new stars. Interestingly, IC 3430 does feature a core of hot, massive blue stars —an uncommon sight in elliptical galaxies — that indicates recent star-forming activity. Astronomers think that pressure from the galaxy ploughing through gas within the Virgo cluster ignited what gas IC 3430 had in its core to form the newer stars.

Dwarf galaxies are really just galaxies with fewer stars, usually less than a billion, but that is often enough for them to reproduce, in miniature, the same forms as larger galaxies. There are dwarf elliptical galaxies like IC 3430, dwarf irregular galaxies, dwarf spheroidal galaxies, and even dwarf spiral galaxies!

The Cygnus space freighter with its two cymbal-shaped solar arrays is pictured attached to the Canadarm2 robotic arm before its release from the space station’s on July 12, 2024.

Thursday’s main activities aboard the International Space Station on Thursday were Cygnus cargo craft preparations and microgravity science. Amidst the mission and research duties, the two crews living and working aboard the orbital outpost also kept up standard household duties and plumbing tasks.

Northrop Grumman’s Cygnus resupply ship is targeted to launch atop a SpaceX Falcon 9 rocket at 11:29 a.m. EDT on Saturday from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Cygnus is planned to take a day-and-a-half trip around Earth before arriving at the space station for its robotic capture at 6 a.m. on Monday.

NASA Flight Engineers Matthew Dominick and Jeanette Epps practiced Cygnus capture techniques on Thursday using the Canadarm2 robotic arm and guiding it toward a grapple fixture on the Permanent Multipurpose Module (PMM). Dominick will be commanding the Canadarm2 to capture Cygnus early Monday while Epps will back him up and monitor Cygnus’ approach and rendezvous.

Epps began her day with blood and saliva sample collection work, processing the specimens for analysis, then stowing the samples in a science freezer and the Kubik research incubator for future retrieval. Dominick set up a notebook computer and connected it to the advanced resistive exercise device for an experiment that measures how muscles and bones are impacted when working out in space.

Tracy C. Dyson and Mike Barratt, both Expedition 71 Flight Engineers, worked on science maintenance and housekeeping tasks throughout the day. Dyson swapped samples and components inside a flame research device that safely studies how materials burn in weightlessness aboard the Kibo laboratory module. Barratt measured the airflow in the Harmony module’s port side crew quarters to ensure the upkeep of ventilation systems and maintain crew health.

NASA astronauts Butch Wilmore and Suni Williams, Commander and Pilot for Boeing’s Crew Flight Test, spent their day on a variety of household tasks. Wilmore first organized food stowed in the Unity module and the PMM then installed a light meter on the Veggie botany research facility. Williams deep cleaned Unity temporarily uninstalling racks and hardware to access and wipe down hard to reach areas with disinfectant.

Station Commander Oleg Kononenko from Roscosmos began his day checking laptop computers before spending the afternoon photographing crew activities and inspecting windows in the Zvezda service module. Flight Engineer Nikolai Chub was back on physics research Thursday as he studied how fluids are affected by magnetic and electrical fields in space. Flight Engineer Alexander Grebenkin worked throughout the day an orbital plumbing and life support tasks in the station’s Roscosmos segment.

As part of NASA’s SpaceX Crew-10 mission, four crew members are preparing to launch for a long-duration stay aboard the International Space Station.

NASA astronauts Commander Anne McClain and Pilot Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Mission Specialist Takuya Onishi, and Roscosmos cosmonaut Mission Specialist Kirill Peskov will join astronauts at the orbiting laboratory no earlier than February 2025.

The flight is the 10th crew rotation with SpaceX to the station as part of NASA’s Commercial Crew Program. While aboard, the international crew will conduct scientific investigations and technology demonstrations to help prepare humans for future missions and benefit people on Earth.

Selected by NASA as an astronaut in 2013, this will be McClain’s second spaceflight. A colonel in the U.S. Army, she earned her bachelor’s degree in Mechanical Engineering from the U.S. Military Academy at West Point, New York, and holds master’s degrees in Aerospace Engineering, International Security, and Strategic Studies. The Spokane, Washington, native was an instructor pilot in the OH-58D Kiowa Warrior helicopter and is a graduate of the U.S. Naval Test Pilot School in Patuxent River, Maryland. McClain has more than 2,300 flight hours in 24 rotary and fixed-wing aircraft, including more than 800 in combat, and was a member of the U.S. Women’s National Rugby Team. On her first spaceflight, McClain spent 204 days as a flight engineer during Expeditions 58 and 59 and was the lead on two spacewalks, totaling 13 hours and 8 minutes. Since then, she has served in various roles, including branch chief and space station assistant to the chief of NASA’s Astronaut Office.

Ayers is a major in the U.S. Air Force and the first member of NASA’s 2021 astronaut class named to a crew. The Colorado native graduated from the Air Force Academy in Colorado Springs with a bachelor’s degree in Mathematics and a minor in Russian, where she was a member of the academy’s varsity volleyball team. She later earned a master’s in Computational and Applied Mathematics from Rice University in Houston. Ayers served as an instructor pilot and mission commander in the T-38 ADAIR and F-22 Raptor, leading multinational and multiservice missions worldwide. She has more than 1,400 total flight hours, including more than 200 in combat.

With 113 days in space, this mission also will mark Onishi’s second trip to the space station. After being selected by JAXA in 2009, he flew as a flight engineer for Expeditions 48 and 49 became the first Japanese astronaut to robotically capture the Cygnus spacecraft. He also constructed a new experimental environment aboard Kibo, the station’s Japanese experiment module. Since his spaceflight, Onishi became certified as a JAXA flight director, leading the team responsible for operating Kibo from JAXA Mission Control in Tsukuba, Japan. He holds a bachelor’s degree in Aeronautics and Astronautics from the University of Tokyo and was a pilot for All Nippon Airways, flying more than 3,700 flight hours in the Boeing 767.

NASA’s SpaceX Crew-10 mission also will be Peskov’s first spaceflight. Before his selection as a cosmonaut in 2018, he earned a degree in Engineering from the Ulyanovsk Civil Aviation School and was a co-pilot on the Boeing 757 and 767 aircraft for airlines Nordwind and Ikar. Assigned as a test-cosmonaut in 2020, he has additional experience in skydiving, zero-gravity training, scuba diving, and wilderness survival.

For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.

NASA has officially announced the 2025 Revolutionary Aerospace Systems Concepts – Academic Linkage (RASC-AL) competition, an initiative to fuel innovation for aerospace systems concepts, analogs, and technology prototyping through university engagement. RASC-AL, one of NASA’s longest-running student competitions, solicits concepts from the next generation of engineers and scientists to explore the future of deep space exploration.

RASC-AL is seeking proposals from the university community to develop new concepts that leverage innovation to improve our ability to operate on the Moon, Mars and beyond. This year’s themes range from developing large-scale lunar surface architectures enabling long-term, off-world habitation, to designing new systems that address objective characteristics and needs and leverage human-scale exploration infrastructure for new science paradigms.

Through RASC-AL, teams and their faculty advisors will design innovative solutions with supporting original engineering and analysis in response to one of the following four themes:
Sustained Lunar Evolution – An Inspirational Moment
Advanced Science Missions and Technology Demonstrators for Human-Mars Precursor Campaign
Small Lunar Servicing and Maintenance Robot

“The RASC-AL competition is a wellspring for groundbreaking ideas,” said Dan Mazanek, Assistant Branch Head for the Exploration Space Mission Analysis Branch (SMAB) at NASA’s Langley Research Center in Hampton, Virginia. “It fosters creativity and pushes the boundaries of what is possible in space exploration. We are looking for innovative solutions that can advance our capabilities beyond Earth’s orbit and pave the way for sustainable lunar exploration and beyond.”

Interested undergraduate and graduate university student teams and their faculty advisors should submit a Notice of Intent by October 16, 2024, and submit proposals and videos by February 24, 2025. Based on review of the team proposal and video submissions in March, up to 14 teams will be selected to advance to the final phase of the competition – presenting their concepts to a panel of NASA and industry judges in a competitive design review at the 2025 RASC-AL Forum in Cocoa Beach, Florida next June.

In addition to their research, teams are also highly encouraged to develop a prototype of part or all of their concept to demonstrate its key functions. Each finalist team will receive a $6,500 stipend to facilitate their full participation in the 2025 RASC-AL Competition, and the top two overall teams will be awarded with additional travel stipends to present their concept at an aerospace conference later in 2025.

Dr. Christopher Jones, Chief Technologist for the Systems Analysis and Concepts Directorate (SACD) at NASA Langley, emphasized RASC-AL’s distinctive fusion of educational value with real-world experience. “RASC-AL provides students with a unique opportunity to engage directly with NASA’s vision for space exploration. Participants not only gain hands-on experience in developing aerospace concepts but also contribute fresh perspectives that the Agency can take as inspiration for future missions and technologies.”

The call for proposals is now open, with proposal submissions due by February 24, 2025. Interested student teams are encouraged to visit the official RASC-AL competition website for detailed guidelines and eligibility requirements.

RASC-AL is sponsored by the Strategy and Architecture Office within the Exploration Systems Development Mission Directorate at NASA Headquarters, and by SMAB within SACD at NASA Langley. It is administered by the National Institute of Aerospace.

Landsat 9’s Operational Land Imager-2 captured this image of the open pits and ponds of Telfer Mine and the surrounding rust-colored soil on Dec. 15, 2023. The soils have a reddish tint from the iron oxides that have accumulated from millions of years of weathering. This part of Western Australia is known for being rich in natural resources, including petroleum, iron ore, copper, and certain precious metals. Beneath the soils, veins of gold and silver run through sedimentary rocks, such as quartz sandstone and siltstone, that formed about 600 million years ago, when much of Australia was under water.
