—Futurism: “Something Weird is Going On with the Asteroid NASA Smashed“

Nearly a year ago, NASA successfully smashed an asteroid for the first time, in a landmark test to see whether we could divert a killer space rock before disaster — but now, the asteroid in question is behaving strangely. As New Scientist reports, a schoolteacher and his pupils seem to have discovered that the orbit of Dimorphos, the space rock socked by the Double Asteroid Redirection Test (DART) last September, has apparently continued slowing down, unexpectedly, in the year since the refrigerator-sized craft smashed into it.

—Kindai University: “Possible Existence of Earth-Like Planet Predicted in the Outskirts of the Solar System“

Researchers from Japan predict, based on computer simulations, the likely existence of an Earth-like planet in the distant Kuiper Belt. There are many unexplained anomalies in the orbits and distribution of trans-Neptunian objects, small celestial bodies located at the outer reaches of the solar system. Now, based on detailed computer simulations of the early outer solar system, researchers from Japan predict the possibility of an undiscovered Earth-like planet beyond Neptune orbiting the Sun. Should this prediction come true, it could revolutionize our understanding of the history of the solar system.

—European Space Agency: “X-ray mission lifts off to study high-energy Universe“

The Japan Aerospace Exploration Agency’s (JAXA) X-Ray Imaging and Spectroscopy Mission (XRISM) lifted off on a H-IIA rocket from the Tanegashima Space Center in Japan at 08:42 JST / 00:42 BST / 01:42 CEST on 7 September 2023. The successful launch marks the beginning of an ambitious mission to explore the growth of galaxy clusters, the chemical make-up of the Universe, and the extremes of spacetime. XRISM is a collaboration between JAXA and NASA, with significant participation from ESA.

This week’s image is from the Hubble Space Telescope. It shows a fantastic array of colors from a portion of NGC 6530, which is about 4,350 light-years from Earth.

Here is more about this image from the European Space Agency (ESA):

A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope…The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. It is the nebula that gives this image its distinctly smokey appearance; clouds of interstellar gas and dust stretch from one side of this image to the other.

You can also watch this short video that pans over the cluster.

A New Crew Departs for the ISS

A new crew departed Earth for the International Space Station (ISS) at 3:27am ET today from NASA’s Kennedy Space Center in Florida via a SpaceX Falcon 9 rocket. The crew includes:

  • NASA astronaut Jasmin Moghbeli,
  • ESA (European Space Agency) astronaut Andreas Mogensen,
  • JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and
  • Roscosmos cosmonaut Konstantin Borisov.

The new crew should be onboard the ISS tomorrow morning, bringing the number of occupants at the station to 11 until 4 crew members return to Earth in a few days.

Russia is probably happy to have attention back on the ISS rather than the Moon for the moment. It has not been a good week for the Russian space program.

You can read more about the new crew members at this NASA site.

Pic of the Week: Glowing Galaxy NGC 6684

This week’s image is from NASA/European Space Agency’s (ESA) Hubble Space Telescope. It shows the glowing galaxy NGC 6684, which is around 44 million light-years from Earth.

This oddly shaped galaxy is explained on the ESA’s website:

Lenticular galaxies like NGC 6684 (lenticular means lens-shaped) possess a large disc but lack the prominent spiral arms of galaxies like the Andromeda Galaxy. This leaves them somewhere between elliptical galaxies and spiral galaxies, and lends these galaxies a diffuse, ghostly experience. NGC 6684 also lacks the dark dust lanes that thread through other galaxies, adding to its spectral, insubstantial appearance.

Space Stories: Mars Ascent Vehicle, Dark Matter Stars, and a New Russian Space Station

—NASA/JPJ.com : “NASA Mars Ascent Vehicle Continues Progress Toward Mars Sample Return“

NASA’s Mars Ascent Vehicle (MAV) recently reached some major milestones in support of the Mars Sample Return program. The Mars Ascent Vehicle would be the first launch of a rocket from the surface of another planet. The team developing MAV conducted successful tests of the first and second stage solid rocket motors needed for the launch. Mars Sample Return will bring scientifically selected samples to Earth for study using the most sophisticated instrumentation around the world. This strategic partnership with ESA (European Space Agency) features the first mission to return samples from another planet. The samples currently being collected by NASA’s Perseverance Rover during its exploration of an ancient river delta have the potential to reveal the early evolution of Mars, including the potential for ancient life.

—ScienceNews : “The James Webb Telescope May Have Spotted Stars Powered by Dark Matter“

The James Webb Space Telescope has spotted objects in the early universe that might be a new kind of star — one powered by dark matter. These “dark stars” are still hypothetical. Their identification in JWST images is far from certain. But if any of the three candidates — reported in the July 25 Proceedings of the National Academy of Sciences — turn out to be this new type of star, they could offer a glimpse of star formation in the early universe, hint at the nature of dark matter and possibly explain the origins of supermassive black holes.

—CNN : “Russia Proposes Joint Research Module on Space Station for China, India, Brazil and South Africa“

The head of Russia’s space agency has extended an offer to Moscow’s partners in the BRICS group – Brazil, India, China and South Africa – to participate in the construction of a joint module for its planned orbital space station, state media reported Monday. Construction of the planned space station follows Moscow’s decision last year to end its decades-long partnership with NASA and withdraw from the aging International Space Station – one of the last remaining channels of cooperation between Russia and the United States.
