NASA’s Moon Rocket Exposed to Potential Hurricane on Launchpad
|
|
(Bloomberg) — As Tropical Storm Nicole barrels toward Florida’s East Coast, a $4 billion NASA rocket remains on a launchpad at Kennedy Space Center, where it will ride out the approaching storm.
Nicole is intensifying and is expected to make landfall as early as Wednesday as a Category 1 hurricane with winds of 74 to 95 mph, potentially putting the huge Space Launch System rocket at risk. NASA estimates that the SLS can withstand wind gusts of up to 85 mph (74 knots), as well as sustained winds of 46 mph (40 knots).
The agency had hoped to launch the rocket and uncrewed Orion capsule to the moon as early as Nov. 14. It would be the first of the agency’s Artemis missions to return humans to the lunar surface. But NASA officials late Tuesday opted to delay the launch to Nov. 16 to allow employees time to return to work safely and perform inspections after the storm.
To prepare for Nicole, NASA has powered down Orion and the major pieces of the SLS rocket, according to a NASA blog post. Hard covers have been installed on the vehicle’s launch abort system on top of the rocket, while the crew access arm — the walkway that future astronauts will use to board the rocket — has been retracted and stored. “Teams also are securing nearby hardware and performing walkdowns for potential debris in the area,” NASA wrote.
The space center is at “HURCON III” status, a level of preparedness level for approaching hurricanes in which personnel work to secure the area’s facilities and hardware. NASA will also have a “ride-out” team on site throughout the storm to monitor conditions at the center.
Joel Cline, the tropical program coordinator with the National Weather Service, estimates there is an 80% to 90% chance of sustained tropical force winds along Florida’s space coast, with storm winds approaching the area as early as Wednesday morning. That’s roughly about the threshold that NASA said the rocket can handle.
“What they’re telling you is they’re looking for hurricane force wind gusts, and sustained winds of tropical storm force, which is the most likely probability,” Cline said.
In September, when Hurricane Ian was headed toward NASA’s Kennedy Space Center in Florida, the rocket was also out on the launchpad ahead of its planned mission. However, NASA ultimately decided to roll it back to its massive hangar, called the Vehicle Assembly Building, for shelter from the approaching storm.
NASA probably no longer has time for a rollback of the rocket since it takes roughly three days to prepare and move the vehicle the four miles to the Vehicle Assembly Building. In the meantime, the agency is standing by its decision to remain at the launchpad.
NASA said high winds present the greatest risk — but aren’t expected to exceed what the rocket is designed to withstand. “The rocket is designed to withstand heavy rains at the launch pad and the spacecraft hatches have been secured to prevent water intrusion,” the agency said.
Cline said that officials at Kennedy Space Center are on frequent calls with the National Hurricane Center, the Department of Defense and other entities operating in the area of the storm’s path.
Another concern, Cline said, is that the storm could bring as much as six inches of rain and a storm surge of three to five feet to Florida’s coast.
Kennedy Space Center is located east of Orlando on Florida’s Atlantic coast.

New image from the James Webb Space Telescope shows thousands upon thousands of stars in a galaxy 17 million light years away – Yahoo Canada

The James Webb Space Telescope snapped a new image of a galaxy 17 million light-years away.
-
Thousands upon thousands of stars are visible, many of which are concentrated in the galaxy’s heart.
-
JWST is peering into the hearts of many galaxies to help scientists better understand star formation.
With the power of the James Webb Space Telescope, we can peer into the mysterious hearts of galaxies. And that’s exactly what you’re seeing here, in this new image from Webb of the galaxy NGC 5068.
NGC 5068 is located about 17 million light-years from Earth. For perspective, the Milky Way’s neighborhood of galaxies called the Local Group, is 5 million light-years away. So, this galaxy is beyond what we might consider close.
Each individual dot of white light you can see is a star, per Mashable. NASA said there are thousands upon thousands of stars in this image. And many of them are hanging out at the galaxy’s center, which you can see in the upper left as a bright bar of white light.
This region appears so bright because that’s where most of the stars are concentrated. That’s also where all the action is.
James Webb peers into the hearts of many galaxies to uncover their secrets
Most galaxies have an ultra-bright center due to warm dust that’s heated by massive bursts of star formation, according to the Harvard Smithsonian. And it’s this star formation that astronomers are interested in studying more with the help of JWST.
In fact, NGC 5068 is just one in a series of other galaxies Webb is observing for a project to help us better understand star formation. Webb has also taken images of the spiral galaxy IC 5332:
And the heart of galaxy M74, aka the “Phantom Galaxy”:
The James Webb Space Telescope has the advantage of seeing in the infrared.
Infrared wavelengths are too long for the human eye to detect. But they’re especially important for studying in space because they allow JWST to peer past obstructive visual light that would otherwise block our ability to see into the hearts of galaxies and their bustling environments of star formation.
“By observing the formation of stars in nearby galaxies, astronomers hope to kick-start major scientific advances with some of the first available data from Webb,” NASA said.

ESA – Nicolas Bobrinsky on innovation and risk management | ESA Masterclass – European Space Agency
Innovation is triggered by many drivers. One of these is the constant need for ESA to develop innovative solutions, such as unique spacecraft technologies.
In this first video, Nicolas recalls how he and his team had to think outside the box to find a solution for ESA to communicate with Ulysses. The spacecraft was flying around the north pole of the Sun, which is much farther in deep space than satellites had been launched up to that point.
The success of this solution motivated the decision to build ESA’s first deep-space communications antennas in New Norcia, in Australia, thus enabling many ESA scientific firsts in deep-space exploration.
The antennas would, some decades after, be critically important receivers for the messages sent by the very distant Rosetta probe, on its quest to find and land on the comet 67P/Churyumov–Gerasimenko, and other ESA science and exploration missions such as Mars Express, Venus Express and Cassini-Huygens.
With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.
In four episodes of this new series of ESA Masterclass, Nicolas takes us through major events in his career at ESA, covering cornerstone missions, first attempts, overcoming technical challenges, leading diverse teams and solving the unexpected problems that are part of any space endeavour.

” data-gt-translate-attributes=”[“attribute”:”data-cmtooltip”, “format”:”html”]”>James Webb Space Telescope has captured a detailed image of the barred spiral galaxy NGC 5068. Part of a project to record star formation in nearby galaxies, this initiative provides significant insights into various astronomical fields. The telescope’s ability to see through gas and dust, typically hiding star formation processes, offers unique views into this crucial aspect of galactic evolution.
A delicate tracery of dust and bright star clusters threads across this image from the James Webb Space Telescope. The bright tendrils of gas and stars belong to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image – a composite from two of Webb’s instruments. NASA Administrator Bill Nelson revealed the image on June 2 during an event with students at the Copernicus Science Centre in Warsaw, Poland.
In this image of the barred spiral galaxy NGC 5068, from the James Webb Space Telescope’s MIRI instrument, the dusty structure of the spiral galaxy and glowing bubbles of gas containing newly-formed star clusters are particularly prominent. Three asteroid trails intrude into this image, represented as tiny blue-green-red dots. Asteroids appear in astronomical images such as these because they are much closer to the telescope than the distant target. As Webb captures several images of the astronomical object, the asteroid moves, so it shows up in a slightly different place in each frame. They are a little more noticeable in images such as this one from MIRI, because many stars are not as bright in mid-infrared wavelengths as they are in near-infrared or visible light, so asteroids are easier to see next to the stars. One trail lies just below the galaxy’s bar, and two more in the bottom-left corner. Credit: ESA/Webb, NASA & CSA, J. Lee and the PHANGS-JWST Team
NGC 5068 lies around 20 million light-years from Earth in the constellation Virgo. This image of the central, bright star-forming regions of the galaxy is part of a campaign to create an astronomical treasure trove, a repository of observations of star formation in nearby galaxies. Previous gems from this collection can be seen here (IC 5332) and here (M74). These observations are particularly valuable to astronomers for two reasons. The first is because star formation underpins so many fields in astronomy, from the physics of the tenuous <span class=”glossaryLink” aria-describedby=”tt” data-cmtooltip=”
” data-gt-translate-attributes=”[“attribute”:”data-cmtooltip”, “format”:”html”]”>plasma that lies between stars to the evolution of entire galaxies. By observing the formation of stars in nearby galaxies, astronomers hope to kick-start major scientific advances with some of the first available data from Webb.
This view of the barred spiral galaxy NGC 5068, from the James Webb Space Telescope’s NIRCam instrument, is studded by the galaxy’s massive population of stars, most dense along its bright central bar, along with burning red clouds of gas illuminated by young stars within. This near-infrared image of the galaxy is filled by the enormous gathering of older stars which make up the core of NGC 5068. The keen vision of NIRCam allows astronomers to peer through the galaxy’s gas and dust to closely examine its stars. Dense and bright clouds of dust lie along the path of the spiral arms: These are H II regions, collections of hydrogen gas where new stars are forming. The young, energetic stars ionize the hydrogen around them, creating this glow represented in red. Credit: ESA/Webb, NASA & CSA, J. Lee and the PHANGS-JWST Team
The second reason is that Webb’s observations build on other studies using telescopes including the Hubble Space Telescope and ground-based observatories. Webb collected images of 19 nearby star-forming galaxies which astronomers could then combine with Hubble images of 10,000 star clusters, spectroscopic mapping of 20,000 star-forming emission nebulae from the <span class=”glossaryLink” aria-describedby=”tt” data-cmtooltip=”
” data-gt-translate-attributes=”[“attribute”:”data-cmtooltip”, “format”:”html”]”>Very Large Telescope (VLT), and observations of 12,000 dark, dense molecular clouds identified by the Atacama Large Millimeter/submillimeter Array (ALMA). These observations span the electromagnetic spectrum and give astronomers an unprecedented opportunity to piece together the minutiae of star formation.
With its ability to peer through the gas and dust enshrouding newborn stars, Webb is particularly well-suited to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the VLT. The keen vision at infrared wavelengths of two of Webb’s instruments — MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera) — allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.
The James Webb Space Telescope stands as the apex of space science observatories worldwide. Tasked with demystifying enigmas within our own solar system, Webb will also extend its gaze beyond, seeking to observe distant worlds orbiting other stars. In addition to this, it aims to delve into the cryptic structures and the origins of our universe, thereby facilitating a deeper understanding of our position within the cosmic expanse. The Webb project is an international endeavor spearheaded by NASA, conducted in close partnership with the <span class=”glossaryLink” aria-describedby=”tt” data-cmtooltip=”
