** Meet NG-18: The S.S. Sally Ride – Northrop Grumman – Youtube 

We’re proud to name our NG-18 #Cygnus spacecraft in honor of astronaut Sally Ride. It’s our tradition to name each Cygnus spacecraft after an individual who has played a pivotal role in human spaceflight. Ride was selected in honor of her accomplishment as the first female American to fly in space, as well as her incredible work in creating STEM education opportunities for young girls through her organization, Sally Ride Science.

The Northrop Grumman S.S. Sally Ride Cygnus  cargo spacecraft is set to lift off on a Antares rocket with the NG-18 re-supply mission no earlier than 5:50 a.m. EST, Nov. 6, 2022 from the Mid-Atlantic Regional Spaceport (MARS) Pad 0A on Wallops Island, Virginia: NASA Commercial Resupply Mission NG-18 – Northrop Grumman.

** NG-18 Research: Overview ISS National Lab – YouTube

Mudslides from forest fires cause catastrophic damage in their wake, and research aimed at predicting and possibly preventing them will launch to the International Space Station (ISS) onboard Northrop Grumman’s 18th Commercial Resupply Services mission (NG-18). This is one of more than 20 investigations sponsored by the ISS National Laboratory flying on this mission.

** NG-18 Research: RedWire BioFabrication FacilityISS National Lab – YouTube

Space: is it the final frontier, or could it be the new frontier of regenerative medicine? Bioprinting human tissues for implantation in patients to treat injury or disease would be game-changing.

When Northrop Grumman’s 18th Commercial Resupply Services (NG-18) mission launches to the ISS, it will carry an upgraded version of Redwire Space’s BioFabrication Facility, or BFF, a 3D bioprinter capable of printing human tissue. The project, sponsored by the ISS National Laboratory, will pave the way for in-space bioprinting of tissues—and possibly even organs in the future—that could one day help patients back on Earth.

Chinese taikonauts Chen Dong, Liu Yang and Cai Xuzhe opened the Mengtian lab hatch and entered the new Tiangong space station module on Nov. 3, 2022. Mengtian was launched atop a Long March 5B Y4 on Oct. 31.

** ISS Live video stream – IBM/ISS HD Earth Viewing Experiment

Currently, live views from the ISS are streaming from an external camera mounted on the ISS module called Node 2. Node 2 is located on the forward part of the ISS. The camera is looking forward at an angle so that the International Docking Adapter 2 (IDA2) is visible. If the Node 2 camera is not available due to operational considerations for a longer period of time, a continuous loop of recorded HDEV imagery will be displayed. The loop will have “Previously Recorded” on the image to distinguish it from the live stream from the Node 2 camera. After HDEV stopped sending any data on July 18, 2019, it was declared, on August 22, 2019, to have reached its end of life. Thank You to all who shared in experiencing and using the HDEV views of Earth from the ISS to make HDEV so much more than a Technology Demonstration Payload!

ESO: VLT captures the vast cloudy remains of the Vela supernova remnant

A report for the Halloween season from the European Southern Observatory (ESO):

ESO captures the ghost of a giant star

This image shows a spectacular view of the orange and pink clouds that make up what remains after the explosive death of a massive star — the Vela supernova remnant. This detailed image consists of 554 million pixels, and is a combined mosaic image of observations taken with the 268-million-pixel OmegaCAM camera at the VLT Survey Telescope, hosted at ESO’s Paranal Observatory.  OmegaCAM can take images through several filters that each let the telescope see the light emitted in a distinct colour. To capture this image, four filters have been used, represented here by a combination of magenta, blue, green and red. The result is an extremely detailed and stunning view of both the gaseous filaments in the remnant and the foreground bright blue stars that add sparkle to the image.

A spooky spider web, magical dragons or wispy trails of ghosts? What do you see in this image of the Vela supernova remnant? This beautiful tapestry of colours shows the ghostly remains of a gigantic star, and was captured here in incredible detail with the VLT Survey Telescope, hosted at the European Southern Observatory’s (ESO’s) Paranal site in Chile.

The wispy structure of pink and orange clouds is all that remains of a massive star that ended its life in a powerful explosion around 11 000 years ago. When the most massive stars reach the end of their life, they often go out with a bang, in an outburst called a supernova. These explosions cause shock waves that move through the surrounding gas, compressing it and creating intricate thread-like structures. The energy released heats the gaseous tendrils, making them shine brightly, as seen in this image.

In this 554-million-pixel image, we get an extremely detailed view of the Vela supernova remnant, named after the southern constellation Vela (The Sails). You could fit nine full Moons in this entire image, and the whole cloud is even larger. At only 800 light-years away from Earth, this dramatic supernova remnant is one of the closest known to us.

As it exploded, the outermost layers of the progenitor star were ejected into the surrounding gas, producing the spectacular filaments that we observe here. What remains of the star is an ultra-dense ball in which the protons and electrons are forced together into neutrons — a neutron star. The neutron star in the Vela remnant, placed slightly outside of this image to the upper left, happens to be a pulsar that spins on its own axis at an incredible speed of more than 10 times per second.

Dive into the details of the Vela supernova remnant with these 12 highlights, each showing a different intricate part of the beautiful pink and orange gaseous clouds and the bright stars in the foreground and background.

This image is a mosaic of observations taken with the wide-field camera OmegaCAM at the VLT Survey Telescope (VST), hosted at ESO’s Paranal Observatory in Chile. The 268-million-pixel camera can take images through several filters that let through light of different colours. In this particular image of the Vela remnant, four different filters were used, represented here by a combination of magenta, blue, green and red.

The VST is owned by The National Institute for Astrophysics in Italy, INAF, and with its 2.6-metre mirror it is one of the largest telescopes dedicated to surveying the night sky in visible light. This image is an example from such a survey: the VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS+). For over seven years, this survey has mapped a considerable portion of our home galaxy, allowing astronomers to better understand how stars form, evolve and eventually die.

This image shows the process of going from the raw data captured by a telescope to a stunning astronomical image like the one featured here, showing the Vela supernova remnant as seen with the VLT Survey Telescope (VST). The detector registers the light collected by the telescope. OmegaCAM, the camera attached to the VST, has an array of 32 detectors covering a large field of view. The raw images contain artefacts and instrumental signatures such as dead pixels, shadows, or luminosity variations among detectors. These need to be corrected before the images can be used for scientific purposes. Astronomers correct these effects using calibration data. This process of going from raw to science-ready data is called ‘data reduction’. When an astronomical object is larger than the field of view one needs to stitch together  different images, typically called a mosaic. This also allows us to fill in the gaps in between the detectors.  The brightness of the background can vary among different parts of the mosaic, especially if they were observed on different nights, because of changes in the phase of the Moon and other effects. For instance, the upper-left corner of image 4 is darker than the rest of the image. By comparing overlapping areas between different images this can be corrected for. The mosaiced image is visually inspected, and any residual artefacts are corrected for. This includes, for example, imperfect seams between adjacent images. Astronomical detectors don’t capture colour images. Instead, several images are taken separately through filters that let through light of different wavelengths. These images are then assigned different colours and combined into a final colour image. The final colour image.
