SpaceX Starship Booster Moved to Pad: Pre-orbital Flight 14 | Starbase Texas

SpaceX Starship Booster Moved to Pad: Pre-orbital Flight 14 | Starbase Texas




SpaceX Update: "Booster 21 moved to the pad at Starbase." 

SpaceX is preparing to go to orbit with Starship on Test Flight 14.

Follow updates and watch the event here → https://www.spacex.com/launches/starship-flight-14

The upcoming flight is planned to be the first to send Starship into orbit around Earth. Flight tests until this point have intentionally flown passively safe suborbital trajectories to maximize public safety while allowing for maximum learning. By going to orbit, the next phase of developing Starship to be fully and rapidly reusable can begin.

This will also mark the first time we plan to deploy Starlink V3 satellites into the constellation, delivering a payload that will dramatically expand connectivity speeds and reliability around the world.

Starship’s initial orbital mission is expected to fly at an altitude approximately 275 km above Earth and complete approximately six orbits around the planet over the course of a nearly 10-hour flight, with splashdown targeted in the Pacific Ocean to the west of Chile.

A live webcast of the flight will begin about 30 minutes before liftoff. Coverage is planned to continue through splashdown with the potential for hours of live views from Starship as it orbits Earth. As is the case with all developmental testing, the schedule is dynamic and likely to change, so be sure to stay tuned for updates.

The booster’s primary test objective on Flight 14 will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of Mexico. There have been several modifications to hardware and software to address issues seen on the previous flight.

After stage separation and flip on Flight 13, the Super Heavy booster was able to use all 33 engines on its boostback burn for the first time. In the terminal phase of the burn, the three center engines showed signs of ice clogging that triggered an early end to the maneuver. The booster went on to attempt a landing burn, with 8 of the 13 planned engines reigniting before the booster made a hard splashdown in the Gulf. The Super Heavy on this upcoming flight has hardware modifications to improve filtering to the engines and software changes to enhance relight reliability.

The Starship upper stage’s primary objectives include the first orbital insertion maneuver, the deployment of 26 Starlink V3 satellites, a deorbit burn using a single Raptor engine while in space, and a controlled reentry, descent, and splashdown in the Pacific Ocean. Starship will only execute a burn to enter orbit after the flight control team has ensured there is sufficient redundancy on hardware critical to doing the subsequent deorbit burn at the end of the mission.

Starship will deliver 26 Starlink V3 satellites to orbit for the first time. They aim to greatly expand the network's capacity and user speeds. Each Starlink V3 satellite will add 1 Tbps of capacity to the constellation, for a total of 26 Tbps of capacity added on this mission alone. That’s ~10x the capacity compared to a single launch of V2 mini Starlink satellites on Falcon 9.

After deploying from Starship, the Starlink V3 satellites will unfold their antennas and deploy their solar arrays and make initial contact with the ground and the rest of the Starlink constellation via radio frequency and laser links. The satellites will then begin raising their orbits with their onboard thrusters. Following their on-orbit checkouts, the satellites should begin serving customers as soon as a few weeks after launch.

Three of the satellites have been modified with a suite of cameras to scan Starship’s heatshield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heatshield readiness for return to launch site on future missions.

Several upgrades and experiments related to Starship’s heatshield will also be tested, with some improvements derived directly from data gathered from the Flight 13 Starship as it floated in the Indian Ocean. They include additional retention mechanisms added to tiles in areas deemed to be at highest risk of falling off during ascent, addressing recently discovered areas that offer flow paths behind tiles for plasma, and flying multiple areas with a curved tile design that has shown the ability to reduce heating in the gaps between tiles. And finally, two tiles recovered from Ship 40 are planned to be reflown on Ship 41, marking the first tile reuse for Starship.

NASA plans to use a lunar lander version of Starship to deliver astronauts and cargo to the Moon during the Artemis IV mission and beyond through the Human Landing System (HLS) Program.

Behind the Scenes: China CAS Space Lijian-1 Rocket Launches 9 Satellites

Behind the Scenes: China CAS Space Lijian-1 Rocket Launches 9 Satellites

China successfully launched nine satellites,  including the Qinling-1, Qinling-2, and PEGA-SUS1, from the Dongfeng Commercial Space Innovation Pilot Zone in northwest China at 12:03 (Beijing Time) Sunday, September 20, 2026.

The satellites were carried by a Lijian-1 Y18 carrier rocket and have entered their planned orbits.

The Lijian-1 (Kinetica-1), developed by Chinese commercial space company CAS Space, is a solid-fuel carrier rocket featuring rapid-response capabilities.

The launch mission was a complete success. This launch was the 16th launch for Kinetica-1, and the 17th for CAS Space through its Kinetica family of launch vehicles. This was also the 68th launch from China in 2026.

This Kinetica-1 flight brought the start of another orbital computing constellation into space, and a communication-computing spacecraft demonstrator, alongside seven satellites designed to look back at Earth.

The Chaozhisuan-1 satellite is to be the first of a constellation to be deployed under the same name, of potentially thousands of spacecraft under an alliance established in March 2026 with notable members being Zhipu AI, SenseTime, Beijing Wenge Technology Co. Ltd. and Tsinghua University.

Peng Cheng Laboratory and the Southern University of Science and Technology, both based in Shenzhen, had their GalaxySpace-made 150-kilogram PEGA-SUS1 multi-purpose demonstrator satellite placed into orbit. From space, the satellite will verify its ability to serve as a 5G non-terrestrial network base station, demonstrate a 100 gigabits per second optical laser communication link, and prove artificial intelligence-enabled data processing provided by onboard compute. If it can prove all three, involved companies hope that it will open the way for further integration of space-based communications and computing.

Developed by entities under the Shanghai Academy of Spaceflight Technology (SAST), the Pujiang-4 carbon dioxide and methane emission monitoring satellite was deployed. This satellite will keep watch of known, and highlight abnormal, emission sources found within a 30-kilometer-wide observation area. Monitoring is mainly planned to be conducted on sources within China, to help meet climate goals, but global sources can be observed, also.

A niche trio of satellites launched among the rest is Diting-1A, 1B, and 1C designed to monitor electromagnetic frequencies and their emitting locations for a variety of customers. The trio is operated by Tianjin Xingkan Jiuzhou Technology, while being produced by Changguang Satellite Technology Co. Ltd.

Lastly, there is ‘Yunxiao Pathfinder Satellite' reported to be tasked with remote sensing. The satellite belongs to the Institute of Mechanics, Chinese Academy of Sciences.

Preparing for Lunar South Pole Science Investigations | NASA Artemis Program

Preparing for Lunar South Pole Science Investigations | NASA Artemis Program




Trevor Graff, the Artemis Science Team Hardware and Testing Lead, can be seen deploying a mockup of the Lunar Environment Monitoring Station (LEMS) during testing with the Active Response Gravity Offload System (ARGOS) at NASA's Johnson Space Center in Houston, Texas. LEMS is a compact, autonomous, and self-sustaining seismometer suite designed to carry out continuous, long-term, monitoring of the lunar seismic environment at the South Polar region. The instrument will characterize the regional structure of the Moon’s crust and mantle. This will add valuable information to lunar formation and evolution models. 

LEMS can operate autonomously and sustainably for years at the Moon to collect geophysical measurements continuously during lunar days and nights. LEMS is intended to operate on the lunar surface from three months up to two years and may become a key station in a future global lunar geophysical network.

During NASA's Artemis IV Mission in 2028, landers will bring astronauts to the lunar surface—this time to stay.

Spiral Galaxy NGC 4045 in Virgo | Subaru Telescope

Spiral Galaxy NGC 4045 in Virgo | Subaru Telescope

The spiral galaxy NGC 4045, located in the Virgo constellation, displays two distinct spiral arms extending from its bright central nucleus to its outer regions. A faint blue spiral arm stretches to the right, indicating that stars are actively forming in the outer regions of this galaxy.

Distance from Earth: ~110 million light-years

Below NGC 4045 lies another galaxy, NGC 4045 A. Although it appears close enough to be gravitationally interacting with NGC 4045, it is actually a far more distant galaxy aligned along the same line of sight from Earth, and the two galaxies are not physically associated.

NGC 4045 was discovered by German-British astronomer William Herschel on December 20, 1784. It was also observed by German astronomer Heinrich Louis d'Arrest on April 10, 1863, causing it to be listed a second time in the New General Catalog, as NGC 4046.

Light-toned Deposits in Melas Chasma | NASA's Mars Reconnaissance Orbiter

Light-toned Deposits in Melas Chasma | NASA's Mars Reconnaissance Orbiter

Melas Chasma is a canyon on Mars, the widest segment of the Valles Marineris canyon system, located east of Ius Chasma at 9.8°S, 283.6°E in the Coprates quadrangle. It cuts through layered deposits that are thought to be sediments from an old lake that resulted from runoff of the valley networks to the west.

It has been known since the 1970s when the Viking orbiters took pictures of Mars that there are large (i.e., several kilometers-thick) mounds of light-toned deposits within the central portion of Valles Marineris. More recent higher resolution images of Mars, including this image of Melas Chasma, show that the wall rocks of Valles Mariners also contain similar, albeit thinner, light-toned deposits.

Spectral data from the Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument indicate that the larger mounds are composed of sulfates. A portion of the wall rock deposits are also made up of sulfates, but others contain clays or mixtures of several kinds of hydrated materials, suggesting that multiple aqueous processes within Valles Marineris, formed the variety of deposits we now observe.

This HiRISE enhanced color camera image (less than 1 km in size) was captured by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 265 km  (~165 miles).

NASA's Mars Reconnaissance Orbiter has spent over twenty years (2006-2026) orbiting the Red Planet, collecting valuable scientific data.

The University of Arizona, in Tucson, operates the High Resolution Imaging Science Experiment (HiRISE). It was built by BAE Systems in Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate (SMD), Washington.

Aurora Borealis 'Dancing' over a Marsh in Canada's Northwest Territories

Aurora Borealis 'Dancing' over a Marsh in Canada's Northwest Territories

Photographer John David McKinnon: "Waves of Auroral curtains danced over the peaceful waters of the Foxholes Marsh in Canada's Northwest Territories."

Known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

The Northwest Territories of Canada is bordered by the territories of Nunavut to the east and Yukon to the west, and by the provinces of British Columbia, Alberta, and Saskatchewan to the south; it also touches Manitoba to the southeast at a quadripoint that includes Nunavut and Saskatchewan. The land area of the Northwest Territories is roughly equal to that of France, Portugal, and Spain combined, although its overall area is even larger because of its vast lakes.

Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the second-largest country by total area with the longest coastline of any country. Its border with the United States is the longest international land border.

Shenzhou-23 Crew Conducts Science, Health Checks | China Space Station

Shenzhou-23 Crew Conducts Science, Health Checks | China Space Station

The China Manned Space Agency (CMSA) on September 20, 2026, released its weekly update on the Shenzhou-23 mission, reporting that the crew has continued scientific research, platform maintenance and health monitoring aboard the Tiangong Space Station.

Nearly four months into their mission, the three astronauts—Zhu Yangzhu, Zhang Zhiyuan and Lai Ka-ying—have been steadily advancing their space science and experiment tasks. Over the past week, they carried out routine maintenance of the space station platform and maintained their daily living and health.

Specifically, the crew conducted research on the spatial interaction between viruses and immune metabolism, accumulating key data for long-term in-orbit health protection. They also completed the replacement of the second batch of in-orbit test samples for the debris migration imaging experiment and experiment samples in the on-orbit maintenance and assembly operation cabinet.

In terms of platform care, the crew took microbial samples from the water dispenser outlet and carried out routine microbial prevention and control work inside the station, reinforcing health safeguards for long-term stays. They also completed personal noise exposure dose measurements and conducted regular cleaning, inspection and maintenance of the cabin environment.

For health management, the astronauts completed mass measurements, bone density tests and ultrasound examinations of multiple body parts, including the neck, abdomen, heart, blood vessels and lower limb veins, to continuously monitor changes in their physical condition. While maintaining good exercise habits, they used equipment such as the bone loss countermeasure device to actively counter the physiological effects of weightlessness.

A Zodiacal Night in India

A Zodiacal Night in India

Also known as the false dawn, a luminous band of zodiacal light is captured in this dark night skyscape. The serene view was recorded just before the beginning of astronomical twilight during September's star party at the remote Hanle Dark Sky Reserve, Ladakh, India, planet Earth. 

At about 4,500 meters altitude, the dark sky reserve presents a haven for hardy stargazing and astrophotography enthusiasts. While meteors streak through the night, bright planet Jupiter appears immersed in the faint zodiacal glow near the eastern horizon. Follow the zodiacal band toward the zenith to find open star cluster M44 and a yellowish tinged planet Mars near the center of the frame. In fact, serendipitous detections of interplanetary dust by NASA's Juno spacecraft suggest Mars itself is the source of dust that back scatters sunlight and creates zodiacal light in planet Earth's night.

What's that strangely diffused white light? 
Dust orbiting the Sun. At certain times of the year, a band of sun-reflecting dust from the inner Solar System appears prominently just after sunset—or just before sunrise—and is called zodiacal light. Although the origin of this dust is still being researched, a leading hypothesis holds that zodiacal dust originates mostly from faint Jupiter-family comets and that it slowly spirals into the Sun.

India, officially the Republic of India, is a country in South Asia. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives.

Flight Deck Aurora at 37,000 feet: View over Northern Canada




Photographer Matt Melnyk: "After nearly six months without seeing the aurora on my overseas flights to Europe due to the long daylight hours of the northern summer, it was great to finally see the Northern Lights again! This display was photographed at 37,000 feet over Hudson Bay while flying from Calgary, Canada, to London, UK. From above much of the lower atmosphere, the aurora was incredibly vivid with bright green curtains and pillars accompanied by beautiful red and magenta color higher in the display. It was a spectacular welcome back to dark skies on the transatlantic route. I'm super excited to see what the Equinox will bring on these flights!"

Fengyun-4C was launched on December 27, 2025 to boost the country's ability to monitor extreme weather events and high-impact climate systems with greater precision, according to the China Meteorological Administration (CMA). As the latest member of China's second-generation Fengyun 4 series, the new satellite will replace the aging Fengyun 4A and will operate in a network with the Fengyun 4B satellite. In addition to Earth science, the Fengyun 4C carries advanced instruments for monitoring space weather and is capable of providing early warning data for space weather disturbances, such as solar proton events.

A geostationary (GEO) satellite orbits Earth at about 35,786 km above the equator, appearing stationary relative to the ground, enabling continuous observation and communication over a fixed region. It is positioned in a circular orbit directly above the Earth's equator at an altitude of approximately 35,786 km (22,236 miles), where it completes one orbit in exactly 24 hours, matching Earth's rotation. From the ground, it appears motionless, allowing antennas to remain fixed without tracking the satellite.

Earth Night Colors with Galactic Views | International Space Station

Earth Night Colors with Galactic Views | International Space Station

Expedition 75 flight engineer and NASA astronaut Anil Menon: "Colors at night are beautiful when looking at Earth at night.  Here you can see blues from the squid boats, the bright lights of cities, storms, and the Milky Way, stars, and galaxies rising in the sky. This was shot from the Dragon forward window with 3 second exposures and stitched together into a timelapse. That's what it looks like through the window; just, a little slower."

Microgravity Music Moves | International Space Station

Microgravity Music Moves | International Space Station

Expedition 75 commander, flight engineer, and NASA astronaut Jessica Meir: "Volume up and get your groove on. A bit of weekend dancing on the International Space Station to start your week off right. A friend of mine was shocked when she realized that it was possible to dance in microgravity. Seems we can’t keep this from the world for any longer! The power of music transcends Earth and space."
