Here are some recent stories of interest.

—European Space Agency (ESA): “Sławosz Uznański from Poland Will fly to International Space Station on Rourth Axiom Space Mission“

Axiom Space announced that it is partnering with India, Hungary, and with Poland through ESA to send three national astronauts to the International Space Station on Axiom Mission 4 (Ax-4). ESA project astronaut Sławosz Uznański has been assigned as mission specialist under the command of Axiom Space’s Chief Astronaut Peggy Whitson...The other two Ax-4 crew members are pilot Shubhanshu Shukla from India, and mission specialist Tibor Kapu from Hungary.

—Associated Press: “One Church, Two Astronauts. How a Texas Congregation is Supporting its Members on the Space Station“

…there’s no way on Earth for NASA astronauts Barry “Butch” Wilmore and Tracy Dyson to show up at Providence Baptist Church. They’re in space, orbiting the planet. More specifically, these two members are working on the International Space Station together...Dyson’s six-month mission isn’t scheduled to end until September, but Wilmore and his fellow NASA test pilot, Suni Williams, should have been back weeks ago. They are staying longer than expected following thruster failures and helium leaks on Boeing’s inaugural crew flight for its Starliner capsule. Wilmore and Williams have said they are confident the capsule will return them home safely; engineers are still poring over Starliner test data.

—University of Cambridge: “Astronomers Uncover Risks to Planets that Could Host Life“

Astronomers have discovered that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed. The discovery suggests that the intense UV radiation from these flares could significantly impact whether planets around red dwarf stars can be habitable…According to researchers, UV radiation from stellar flares can either erode planetary atmospheres, threatening their potential to support life, or contribute to the formation of RNA building blocks, which are essential for the creation of life.

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.

Space Stories: Redefining Planets, Second Thoughts About Crashing the ISS, and NASA Preparing for Artemis II

Here are some recent stories of interest.

—Space.com: “‘What Exactly is a Planet?’ Astronomers Want to Amend the Definition“

Three astronomers last week proposed expanding the official definition of a planet to encompass worlds orbiting stars other than our own, a nuance not currently included in the formal definition of the term established in 2006 by the International Astronomical Union, or IAU. If the trio’s new definition pans out, thousands of celestial bodies across the universe could be confirmed as formal planets.

—Forbes: “U.S. Plan To Crash Space Station Is Condemned By Space Agency Leaders“

An American plan to destroy the International Space Station by propelling it to burn through the atmosphere, and then crashing it into the Pacific Ocean, would rob citizens of the future of one of civilization’s greatest technological masterworks, and should be halted, say one-time leaders of NASA and of the European Space Agency. NASA’s draft blueprints to send the ISS on a peacetime kamikaze mission, to explode on impact with Antarctic waters, would obliterate a pole star of human ingenuity, says Jean-Jacques Dordain, Director General of the European Space Agency when the ISS was being built and expanded.

—NASA: “‘NASA Barge Preparations Underway for Artemis II Rocket Stage Delivery“

Team members are installing pedestals aboard NASA’s Pegasus barge to hold and secure the massive core stage of NASA’s SLS (Space Launch System) rocket, indicating NASA barge crews are nearly ready for its first delivery to support the Artemis II test flight around the Moon. The barge will ferry the core stage on a 900-mile journey from the agency’s Michoud Assembly Facility in New Orleans to its Kennedy Space Center in Florida…Measuring 212 feet in length and 27.6 feet in diameter, the core stage is the largest rocket stage NASA has ever built and the longest item ever shipped by a NASA barge.

Pic of the Week: Omega Centauri

The colorful image this week is from the Hubble Space Telescope. It shows the stars that make up Omega Centauri, a globular cluster one can view with the naked eye.

Here’s a little more about this image from the European Space Agency (ESA):

Omega Centauri is visible from Earth with the naked eye and is one of the favourite celestial objects for stargazers in the southern hemisphere. Although the cluster is 17 000 light-years away, lying just above the plane of the Milky Way, it appears almost as large as the full Moon when seen from a dark rural area. The exact classification of Omega Centauri has evolved through time, as our ability to study it has improved. It was first listed in Ptolemy’s catalogue nearly two thousand years ago as a single star. Edmond Halley reported it as a nebula in 1677, and in the 1830s the English astronomer John Herschel was the first to recognise it as a globular cluster. Omega Centauri consists of roughly 10 million stars that are gravitationally bound.

Europe is Back in the Space Race

Earlier today, the European Space Agency (ESA) successfully launched an Ariane 6 rocket, the next generation of European space rockets. The launch was from the ESA’s Guiana Space Centre in French Guiana.

Europe is once again moving away from it dependence on US and Russian rockets to get its space program into space. The launch of the new rocket has been delayed for years while the Ariane 5 flew its last mission about a year ago.

On it’s Twitter page, the ESA stated:

We have now entered into a new era of spaceflight for Europe, powering us into space and allowing us to realise our ambitions on the world stage.

The inaugural flight did experience a problem when part of its test payload failed to deploy. This will need to be investigated and corrected before more critical payloads are placed on a rocket.

That said, all in all it was a good day for the Europeans and space enthusiasts everywhere.
