Resupply Mission to the Space Station Hits a Weather Bump

The weather in Florida has delayed today’s Northrop Grumman resupply mission to the International Space Station (ISS). In fact, SpaceX is launching the payload for Grumman from the Cape Canaveral Space Force Station rather than the typical launch facility in Virginia. The Northrop Grumman Cygnus cargo spacecraft with its 8,200 pounds of supplies will probably need to sit on the launch pad for a few more days until the weather clears.

Why is SpaceX launching a Grumman resupply mission, you might ask?  Doesn’t Grumman have its own rocket? Yes, and no. It has launches most of its resupply missions on its own Antares rocket, but the newest version of the rocket, the Antares 330, is still being finalized and is not expected to be ready until next year. As a result, Grumman procured three flights from SpaceX.

The ability of the commercial parties to support one another’s missions is encouraging, just as the European Space Agency dependied on SpaceX while it developed a new generation of its Ariane rocket.

SpaceX is always there to help (at a cost, of course) as other rocket companies prepare for the challenges ahead. In the case of Northrop Grumman, it needed to move away from its reliance on Ukrainian/Russian rockets and create a more reliable supply chain.

Now we just need the weather to cooperate.

Podcast: Discussion with Ray Kurzweil

Posted on by onespaceman2000

Neil deGrasse Tyson interviews futurist Ray Kurzweil in this repeat StarTalk episode from November 2022 titled “Could We Someday Liver Forever? With Ray Kurzweil.” It is a heavy conversation about living forever as we integrate technology even more into our lives. Throughout the conversation Neil makes reference to a book coming out in 2023. In fact, the book came out in June of this year, which is probably why the episode is available again.

Here is a description of the new book from the publisher:

In this entirely new book Ray Kurzweil brings a fresh perspective to advances toward the Singularity—assessing his 1999 prediction that AI will reach human level intelligence by 2029 and examining the exponential growth of technology—that, in the near future, will expand human intelligence a millionfold and change human life forever. Among the topics he discusses are rebuilding the world, atom by atom with devices like nanobots; radical life extension beyond the current age limit of 120; reinventing intelligence by connecting our brains to the cloud; how exponential technologies are propelling innovation forward in all industries and improving all aspects of our well-being such as declining poverty and violence; and the growth of renewable energy and 3-D printing. He also considers the potential perils of biotechnology, nanotechnology, and artificial intelligence, including such topics of current controversy as how AI will impact employment and the safety of autonomous cars, and “After Life” technology, which aims to virtually revive deceased individuals through a combination of their data and DNA.

The culmination of six decades of research on artificial intelligence, The Singularity Is Nearer is Ray Kurzweil’s crowning contribution to the story of this science and the revolution that is to come.

You will want listen to the podcast interview, and afterward you might even want to pick up the book.

Pic of the Week: View of a Nearby Exoplanet

This week’s image looks dark and simple, and yet it is an amazing sight provided by NASA’s James Webb Space Telescope (JWST). It shows a directly imaged exoplanets that resides about 12 light-years from us. It is called Epsilon Indi Ab and is several times the mass of Jupiter.

Here is an explanation from NASA about what you are seeing in the image:

This image of the gas-giant exoplanet Epsilon Indi Ab was taken with the on NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument). A star symbol marks the location of the host star Epsilon Indi A, whose light has been blocked by the coronagraph, resulting in the dark circle marked with a dashed white line. Epsilon Indi Ab is one of the coldest exoplanets ever directly imaged. Light at 10.6 microns was assigned the color blue, while light at 15.5 microns was assigned the color orange. MIRI did not resolve the planet, which is a point source.

More from the Chandra X-ray Observatory

The images released to celebrate the 25th anniversary of the Chandra X-ray Observatory are too beautiful to be visited only once. Above is another amazing image from the collection showing the Crab Nebula.

Here is a little more about this image from NASA:

This composite image features the remnant of a supernova explosion, which resembles a neon purple mushroom at the heart of a colorful web of veins and filaments. Known as the Crab Nebula, the heavily veined blue and red cloud of gas is set against the blackness of space. At the core of the nebula is a pulsar, a rotating neutron star emitting electromagnetic radiation. Here, the pulsar appears as a bright white dot sitting in a neon purple cloud. Surrounding the dot are white rings. These are created by particles driven away from the pulsar and colliding with gas in the nebula to produce X-rays. From this angle, the rings and purple cloud combine to resemble a mushroom cap. Completing the look of a mushroom is a thin mushroom stem emerging from the white dot. This is a narrow beam of particles blasting away from the pulsar.

And below is one more image, NGC 1850, with this narrative from NASA:

This composite image features a double star cluster, a blue-tinted cloud, and several neon purple dots. This double cluster is part of the Large Magellanic Cloud, a companion galaxy to the Milky Way. The bright, golden stars in the larger cluster fill the upper center of the image. The other cluster is much smaller and coincides with one of the neon purple circles located slightly above and to the right of the image’s center. This and the other purple circles are X-ray sources detected with Chandra. To our left of the combined cluster is a vertical streak of blue-tinted cloud. Extending beyond the upper and lower edges of the image, this section of cloud resembles wafting smoke from a cigarette.

Space Stories: Good Time to View the Heavens, Nearby Super-Jupiter, and Spotting Deepfakes

Here are some recent stories of interest.

—Live Science: “Why the 1st Week of August is the Best Time to See ‘Shooting Stars’ and the Milky Way — No Telescope Required“

The arrival of August means two things for stargazers — “shooting stars” and the Milky Way. In 2024, you can see both at the same time if you know exactly where and when to look…This month, there’s a new moon on Aug. 4, which will keep the post-sunset sky dark until about Aug. 8. That makes the first week of August ideal for spotting “shooting stars” — while you also look for the Milky Way. True darkness won’t come until midnight for most of the Northern Hemisphere, but look to the southeast after dark, and you’ll have a chance of seeing the Sagittarius arm of the Milky Way arching across the night sky.

—Max Planck Institute for Astronomy: “Webb Images Nearest Super-Jupiter, Opening a New Window to Exoplanet Research“

Using the James Webb Space Telescope (JWST), an MPIA-led team of astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST’s unprecedented imaging capabilities in the thermal infrared. It exemplifies the potential of finding many more such planets similar to Jupiter in mass, temperature, and orbit. Studying them will improve our knowledge of how gas giants form and evolve in time.

—Nature: “AI ‘Deepfake’ Faces Detected Using Astronomy Methods“

Researchers are turning to techniques from astronomy to help spot computer-generated ‘deepfake’ images — which can look identical to genuine photographs at first glance. By analysing images of faces using methods that are usually used to survey distant galaxies, astronomers can measure how a person’s eyes reflect light, which can reveal telltale signs of image manipulation.
