“An attempt to do a cost-benefit analysis on ISS science would be rather difficult. Science research rarely conforms to that kind of examination while it’s being done. Only after the fact, when an entrepreneur rolls out some new product or service, can one point to something done in a laboratory as having helped to make it happen. The best bet for ISS science is the technology for 3D printing human organs for transplant patients. The number of lives that would be saved might make the $100 billion spent on the ISS worth it.”
-Statement in a recent editorial from The Hill titled, “Has the science on NASA’s International Space Station been worth the money?” In addition to 3D printing of human organs, you might want to view the other ISS achievements (also mentioned in the editorial) and decide for yourself:

Space company Virgin Orbit, owned by Richard Branson, has filed for bankruptcy after failing to raise sufficient funds to stay afloat. All of this follows a failed rocket launch back in January that set the company back.
Dan Hart, CEO of Virgin Orbit, stated in a company press release:
The team at Virgin Orbit has developed and brought into operation a new and innovative method of launching satellites into orbit, introducing new technology and managing great challenges and great risks along the way as we proved the system and performed several successful space flights – including successfully launching 33 satellites into their precise orbit. While we have taken great efforts to address our financial position and secure additional financing, we ultimately must do what is best for the business. We believe that the cutting-edge launch technology that this team has created will have wide appeal to buyers as we continue in the process to sell the Company. At this stage, we believe that the Chapter 11 process represents the best path forward to identify and finalize an efficient and value-maximizing sale.
It’s the sad end of a company that hoped to launch a “space revolution.” That task will now need to be taken up by others.
Byrne and Hahn’s new study includes detailed analyses of where volcanoes are, where and how they’re clustered, and how their spatial distributions compare with geophysical properties of the planet such as crustal thickness. Taken together, this work provides the most comprehensive understanding of Venus’ volcanic properties — and perhaps of any world’s volcanism so far. That’s because, although we know a great deal about the volcanoes on Earth that are on land, there are still likely a great many yet to be discovered under the oceans. Lacking oceans of its own, Venus’ entire surface can be viewed with Magellan radar imagery.
Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. The signal suggests that the Earth-size planet may have a magnetic field and perhaps even an atmosphere…Scientists noticed strong radio waves coming from the star YZ Ceti and the rocky exoplanet that orbits it, called YZ Ceti b, during observations using the Karl G. Jansky Very Large Array of telescopes in New Mexico. The researchers believe the radio signal was created by interactions between the planet’s magnetic field and the star.
A young, ultrabright Jupiter may have desiccated its now hellish moon Io. The planet’s bygone brilliance could have also vaporized water on Europa and Ganymede, planetary scientist Carver Bierson reported March 17 at the Lunar and Planetary Science Conference. If true, the findings could help researchers narrow the search for icy exomoons by eliminating unlikely orbits. Jupiter is among the brightest specks in our night sky. But past studies have indicated that during its infancy, Jupiter was far more luminous. “About 10 thousand times more luminous,” said Bierson, of Arizona State University in Tempe.

Another step was taken today to get us closer to a Moon landing. Earlier today NASA announced the names of the four astronauts on the next Artemis II mission:
The Artemis II mission will require the four astronauts to take an Orion capsule around the Moon to test a variety of systems and ensure the safety of a later Moon landing as part of Artemis III. You can see a graphic of the Artemis II mission below.
At today’s ceremony announcing the crew, NASA Administrator Bill Nelson stated:
The Artemis II crew represents thousands of people working tirelessly to bring us to the stars. This is their crew, this is our crew, this is humanity’s crew…NASA astronauts Reid Wiseman, Victor Glover, and Christina Hammock Koch, and CSA astronaut Jeremy Hansen, each has their own story, but, together, they represent our creed: E pluribus unum – out of many, one. Together, we are ushering in a new era of exploration for a new generation of star sailors and dreamers – the Artemis Generation.
