Space Quote: ISS is Closed to Visitors at the Moment

“NASA and Axiom Space are postponing the launch of Axiom Mission 4 to the International Space Station. As part of an ongoing investigation, NASA is working with Roscosmos to understand a new pressure signature, after the recent post-repair effort in the aft most segment of the International Space Station’s Zvezda service module.”

Statement by NASA regarding an leak in the Russian section of the International Space Station (ISS) that has yet to be resolved. This may slow down some of the space tourism to the site, such as the already delayed Axiom Mission, but it is more important to get this right rather than risk additional lives on the station. Axiom Space stated that the launch of the mission will be no earlier than June 19.

Protect NASA Astrobiology Research

The astrobiology community is looking for individuals to show their support for NASA’s efforts in this area. In a white paper highlighting the benefits of astrobiology research, some of the key points are:

  • Preserve Astrobiology Leadership: Astrobiology is a pillar of NASA’s mission with a storied legacy that must be safeguarded.
  • Unprecedented Discoveries Ahead: Mars, Ocean Worlds, and exoplanet missions in the coming decades could finally answer one of humanity’s most profound questions: “are we alone?
  • Public Passion and Impact: The public passionately supports the search for life – a pursuit that inspires, unites, and advances STEM engagement.
  • NASA’s Unique Role: NASA’s unique capabilities and infrastructure position it as a leader in astrobiology, working in collaboration with U.S. academia and industry to advance this field.
  • Preserve Astrobiology at Its Peak: Astrobiology is thriving; workforce and research funding reductions must not derail our best chance to find life beyond Earth.

At a time of unprecedented threats to NASA’s program and mission, it is important to send a message to Congress and others that we have just begun to understand the universe and its potential for other forms of life, and now is not the time to back away.

The paper notes:

As NASA navigates the administration’s government-wide workforce optimization initiative, it is vital that we do not undermine astrobiology research – a field at the very heart of our agency’s purpose and future. Acting leadership has rightly stated that any reductions must align with mission needs. Few needs are more central to NASA’s science mission than understanding life’s existence beyond Earth.

I expect this is one of many initiatives to bring attention to the threats facing our space program. It is true that some efficiencies can be found in government with the right level of analysis and careful consideration of existing programs (as has been done in the past), but that is not happening right now with the random and unexplainable cuts.

U.S. Postal Service Stamps Highlight JWST Images

The U.S. Postal Service is honoring NASA again with a set of stamps highlighting images captured by the James Webb Space Telescope (JWST) – star cluster IC 348 (above) and spiral galaxy NGC 628 (below).

Regarding star cluster IC 348, NASA notes:

The wispy curtains filling the image are interstellar material reflecting the light from the cluster’s stars – what is known as a reflection nebula. This scene is located 1,000 light-years from Earth in the constellation Perseus.

Regarding spiral galaxy NGC 628, NASA explains:

Webb’s observations combine near- and mid-infrared light to reveal glowing gas and dust in stark shades of orange and red, as well as finer spiral shapes with the appearance of jagged edges. This galaxy is located 32 million light-years away in the constellation Pisces. 

I would have preferred these stamps were regular first class forever stamps so that they would grace personal letters and birthday cards traveling to every corner of this country, but this is a nice gesture however you look at it.

Movie Quote: Not Such an Alien World

The production design harkens back to both Scott and Cameron’s ALIEN movies. It’s a world we recognize so there’s not much new world-building except for the brief glance at an active mining colony. What’s different is the cinematography by Galo Olivares…ALIEN: ROMULUS works as a stand-alone movie, and is probably a better experience if you come in cold, without any knowledge of the franchise. ALIEN fans bring in too much baggage and rarely can we be satisfied.”

-Statement by movie critic Lupe R Haas in her recent review of the film Alien: Romulus.

Study Findings: Feasibility of Keeping Mars Warm with Nanoparticles

Science Advances abstract of the study findings:

One-third of Mars’ surface has shallow-buried H2O, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require a large mass of ingredients that are rare on Mars’ surface. However, we show here that artificial aerosols made from materials that are readily available at Mars—for example, conductive nanorods that are ~9 micrometers long—could warm Mars >5 × 103 time smore effectively than the best gases. Such nanoparticles forward-scatter sunlight and efficiently block upwelling thermal infrared. Like the natural dust of Mars, they are swept high into Mars’ atmosphere, allowing delivery from the near-surface. For a 10-year particle lifetime, two climate models indicate that sustained release at 30 liters per second would globally warm Mars by ≳30 kelvin and start to melt the ice. Therefore, if nanoparticles can be made at scale on (or delivered to) Mars, then the barrier to warming of Mars appears to be less high than previously thought.
