Hague is pictured holding a spacewalking camera in front of his spacesuit's helmet shield.

The Neutron star Interior Composition Explorer (NICER) X-ray telescope is pictured installed on the starboard side of the International Space Station's integrated truss segment. NICER's 56 X-ray concentrators are covered by thermal shields, or filters, that block ultraviolet, infrared, and visible light while allowing X-rays to pass through to the mirrors underneath enabling the observation of neutron stars. Several thermal shields have been damaged allowing unwanted sunlight to "leak" into the astrophysics instrument interfering with X-ray measurements. NASA astronauts Nick Hague and Sun Williams will conduct a spacewalk on Jan. 16 to patch the damaged thermal shields and restore NICER for daytime scientific operations.

NASA astronauts Suni Williams and Nick Hague concluded their spacewalk at 2:01 p.m. EST on Thursday, January 16, 2025. It was the fourth spacewalk for Hague and the eighth for Williams, and it was the 273rd spacewalk in support of space station assembly, maintenance, and upgrades.

Williams and Hague completed their primary objectives, including removing and replacing a rate gyro assembly, installing patches to cover damaged areas of light filters on the Neutron star Interior Composition Explorer (NICER) x-ray telescope, and replacing a reflector device on one of the international docking adapters. The pair also checked access areas and connector tools that astronauts will use for future Alpha Magnetic Spectrometer maintenance.

NASA's New Pandora SmallSat Mission to Study Exoplanet Atmospheres

NASA's New Pandora SmallSat Mission to Study Exoplanet Atmospheres

Pandora, NASA’s newest exoplanet mission, is one step closer to launch with the completion of the spacecraft bus that will provide the structure, power, and other systems enabling the mission to conduct its work.

Pandora is a small satellite that will provide in-depth studies of at least twenty known planets orbiting distant stars in order to determine the composition of their atmospheres—especially the presence of hazes, clouds, and water. This data will establish a firm foundation for interpreting measurements by NASA’s James Webb Space Telescope and future missions that will search for habitable worlds.

Astronomers view the presence of water as a critical aspect of habitability because water is essential to life as we know it. However, variations in light from a planet's host star can mask or mimic the signal of water. Separating these sources is will be Pandora's task.

Using a novel all-aluminum, 45-centimeter-wide (17 inches) telescope, Pandora’s detectors will capture each star’s visible brightness and near-infrared spectrum at the same time, while also obtaining the transiting planet’s near-infrared spectrum. This combined data will enable the science team to determine the properties of stellar surfaces and cleanly separate star and planetary signals.

Over the course of its year-long prime mission, Pandora will observe at least twenty exoplanets ten times with each one lasting a total of 24 hours. Each observation will include a transit, when the exoplanet passes in front of its star as seen from our perspective. This is when the mission will capture the planet’s spectrum.

Exoplanets Need to be Prepared for Extreme Space Weather | NASA Chandra

Exoplanets Need to be Prepared for Extreme Space Weather | NASA Chandra

Planets around most other stars in the known universe need to be prepared for extreme space weather conditions, according to a new study from NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton space observatory that examined the effects of X-rays on potential planets around the most common type of stars.

Astronomers found that only a planet with greenhouse gases in its atmosphere like Earth and at a relatively large distance away from its host star would have a chance to support life as we know it around a nearby star.

Wolf 359 is a red dwarf star with a mass about a tenth that of the Sun. Red dwarf stars are the most common stars in the universe and live for billions of years, providing ample time for life to develop. At a distance of only 7.8 light-years away, Wolf 359 is also one of the closest stars to our Solar System.

The researchers think that Wolf 359 can help them unlock the secrets around stars and habitability because it is so close and belongs to such an important class of stars. Because red dwarfs are the most prevalent types of stars, astronomers have looked hard to find exoplanets around them. While a group of astronomers have said they have found evidence for two planets in orbit around Wolf 359 from optical telescopes, this has not been independently confirmed yet.

Regardless, even the possibility of planets around Wolf 359 is intriguing. Astronomers decided to use NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton to see what the environment for any potential planets would be like there.

They found that Wolf 359 is producing enough damaging radiation that only a planet with greenhouse gases, like carbon dioxide, in its atmosphere—and located at a relatively large distance from the star—would likely be able to sustain life. The team looked at what astronomers call the “habitable zone,” the region around a star where liquid water could exist on a planet’s surface, for Wolf 359. They found that the output of high-energy radiation from Wolf 359 means that any planet located in the habitable zone around it is unlikely to have a significant atmosphere long enough for multicellular life, as we know it on Earth, to form and survive. That is, unless that planet is near the habitable zone's outer edge of a planet and has a significant greenhouse effect.

This result helps astronomers know not only where to look for habitable planets, but also what other factors may be necessary to study to understand where life may be possible beyond our Solar System.

Liftoff of Blue Origin's New Glenn Rocket: Flight NG-1

Liftoff of Blue Origin's New Glenn Rocket: Flight NG-1

Blue Origin's New Glenn rocket successfully lifted off at 2:03 a.m. Eastern Time (ET) from Launch Complex 36 at Cape Canaveral, Florida on January 16, 2025. It safely reached its intended orbit during today's NG-1 mission, accomplishing its primary objective.

About New Glenn

New Glenn stands more than 320 feet (98 meters) high and features a seven-meter payload fairing, enabling twice the volume of standard five-meter class commercial launch systems. Its reusable first stage aims for a minimum of 25 missions and will land on Jacklyn, a sea-based platform located several hundred miles downrange. Reusability is integral to radically reducing cost-per-launch.   

The vehicle is powered by seven of Blue Origin’s BE-4 engines, the most powerful liquefied natural gas (LNG)-fueled, oxygen-rich staged combustion engine ever flown. LNG is cleaner-burning and higher-performing than kerosene-based fuels, and the seven BE-4s generate over 3.8 million lbf of thrust. The vehicle’s second stage is powered by two BE-3Us, liquid oxygen (LOX)/liquid hydrogen (LH2) engines designed to together yield over 320,000 lbf of vacuum thrust.   

In addition to the BE-4 and BE-3U, Blue Origin manufactures BE-7 engines for our Blue Moon lunar landers and New Shepard’s BE-3PM engine.

SpaceX Falcon 9: Liftoff of Two Lunar Landers | Firefly Aerospace & ispace

SpaceX Falcon 9: Liftoff of Two Lunar Landers | Firefly Aerospace & ispace

On Wednesday, January 15, 2025, a SpaceX Falcon 9 launch vehicle successfully launched Firefly Aerospace’s Blue Ghost Mission 1 and ispace's Resilience lunar lander from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida at 1:09 a.m. ET. This was SpaceX’s 100th launch from the historic Launch Complex 39A. The pad was constructed in the 1960s to accommodate the Saturn V launch vehicle, and has been used to support NASA crewed space flight missions, including the historic Apollo 11 moon landing and the Space Shuttle.

This was the fifth flight for the first stage booster supporting this mission. It previously launched Crew-9, RRT-1, and two Starlink missions. Following stage separation, the first stage landed on the Just Read the Instructions droneship stationed in the Atlantic Ocean.

Once deployed into a lunar transfer orbit, the Blue Ghost lander will begin its approximate 45-day journey to the Moon, where it will land in Mare Crisium for NASA’s payloads to perform numerous science and technology demonstrations, including lunar subsurface drilling, sample collection, and X-ray imaging of Earth’s magnetic field to advance research for future human missions on the Moon and provide insights into how space weather impacts the planet.

The Blue Ghost lander flight will deliver ten NASA science instruments and technology demonstrations to the Moon.

After its deployment, the ispace Resilience lander will begin its 4-5 month journey to the Moon. During their mission, ispace aims to achieve a soft landing on the lunar surface, to deploy its Tenacious micro rover, to explore the Moon’s surface, and collect regolith.

DECam y Gemini Sur descubren tres diminutas ciudades fantasmas | NOIRLab

Cosmoview Episodio 93:  Mediante la combinación de datos provenientes del telescopio Gemini Sur, ubicado en Chile, y de la investigación DESI Legacy Imaging Surveys, un equipo de astrónomos descubrió tres galaxias enanas ultra débiles que solo contienen estrellas muy viejas, reforzando la teoría sobre eventos ocurridos en el Universo primitivo que pudieron interrumpir la formación de estrellas en las galaxias más pequeñas. Las galaxias investigadas se encuentran en una región del espacio aislada de la influencia de otros objetos mayores y se encuentran en la dirección de NGC 300.

Estas imágenes se obtuvieron del Estudio DECam Legacy Survey (DECaLS), el cual corresponde a uno de los tres catálogos de imágenes que forman parte del sondeo DESI Legacy Imaging Surveys. Este catálogo de imágenes cubre los 14.000 grados cuadrados del cielo para proporcionar objetivos para el estudio en curso del Instrumento Espectroscópico de Energía Oscura (DESI). DECals se llevó a cabo utilizando la Cámara de Energía Oscura (DECam) de 570 megapíxeles, la cuál está montada en el Telescopio Vícto M. Blanco de 4 metros de NSF, que se encuentra en el Observatorio Interamericano Cerro Tololo (CTIO) de la Fundación Nacional de Ciencias de EE.UU., un Programa de NOIRLab de NSF, en Chile.

Close-up: The Tiny ‘Stellar-Ghost-Town’ Dwarf Galaxies in Sculptor | NOIRLab

By combining data from the DESI Legacy Imaging Surveys and the Gemini South telescope, astronomers have investigated three ultra-faint dwarf galaxies that reside in a region of space isolated from the environmental influence of larger objects. The galaxies, located in the direction of the spiral galaxy NGC 300 and the Scuptor constellation, were found to contain only very old stars, supporting the theory that events in the early Universe cut star formation short in the smallest galaxies.

These images were taken for the DECam Legacy Survey (DECaLS), one of three public surveys that jointly imaged 14,000 square degrees of sky to provide targets for the ongoing Dark Energy Spectroscopic Instrument (DESI) Survey. DECals was conducted using the 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile, a Program of NSF NOIRLab.

Ultra-faint dwarf galaxies are the faintest type of galaxy in the Universe. Typically containing just a few hundred to a thousand stars—compared with the hundreds of billions that make up the Milky Way—these small diffuse structures usually hide inconspicuously among the many brighter residents of the sky. For this reason, astronomers have previously had the most luck finding them nearby, in the vicinity of our own Milky Way Galaxy.

Following separation, the first stage autonomously descends to a landing platform located several hundred miles downrange in the Atlantic. Next, the two BE-3Us ignite, propelling the second stage into space.

"Blue Origin has several New Glenn vehicles in production and a full customer manifest. Customers include NASA, Amazon’s Project Kuiper, AST SpaceMobile, several telecommunications providers, and a mix of U.S. government customers."

About New Glenn 

New Glenn stands more than 320 feet (98 meters) high and features a seven-meter payload fairing, enabling twice the volume of standard five-meter class commercial launch systems. Its reusable first stage aims for a minimum of 25 missions and will land on Jacklyn, a sea-based platform located several hundred miles downrange. Reusability is integral to radically reducing cost-per-launch.   

The vehicle is powered by seven of Blue Origin’s BE-4 engines, the most powerful liquefied natural gas (LNG)-fueled, oxygen-rich staged combustion engine ever flown. LNG is cleaner-burning and higher-performing than kerosene-based fuels, and the seven BE-4s generate over 3.8 million lbf of thrust. The vehicle’s second stage is powered by two BE-3Us, liquid oxygen (LOX)/liquid hydrogen (LH2) engines designed to together yield over 320,000 lbf of vacuum thrust.   

In addition to the BE-4 and BE-3U, Blue Origin manufactures BE-7 engines for our Blue Moon lunar landers and New Shepard’s BE-3PM engine.
