One More Wrinkle Related to the Starliner Delay

As if NASA needed another issue with the Boeing Starliner stranded at the International Space Station (ISS), the media (particularly the Indian media) is now reporting that one of the Starliner astronauts is having eyesight issues.

According to one media source, Astronaut Sunita Williams is experiencing eyesight problems that may be linked to her exposure to microgravity. The issue, called Spaceflight Associated Neuro-ocular Syndrome (SANS), is not an uncommon symptom related to space flight. It can lead to blurred vision over time and worsens over time.

NASA has noted that:

Most astronauts’ eyes and brain structure change in space…Weightlessness causes blood and cerebrospinal fluid to shift toward the head. This fluid shift is believed to be the underlying cause of the eye and brain structural changes…The longer they are in space, the more they may be impacted. Many astronauts only experience effects in space, but some changes may be permanent in some astronauts.

This has only become an issue now that an 8-day tour has turned into a potential 8-month tour. This Gilligan’s Island tour needs to come to an end so that the ISS can return to regular operations.

Volunteer Work Pays Off: Sighted Star on Course to Escape the Milky Way

NASA’s Backyard Worlds: Planet 9 program allows interested volunteers to search earlier data to potentially locate an extra planet or new brown dwarfs near our solar system. Well, one of these volunteers found something unusual – an object with a mass similar to or less than that of a small star that was traveling fast enough to eventually escape the Milky Way’s gravity and enter intergalactic space. This object was clocked at approximately 1 million miles per hour.

You can read about this object and other efforts by visiting this NASA link. You might want to look into becoming part of the citizen scientists looking for more interesting objects.

Space Quote: Vast Water Reserves May Exist Within Martian Crust

“These new results demonstrate that liquid water does exist in the Martian subsurface today, not in the form of discrete and isolated lakes, but as liquid water-saturated sediments, or aquifers…On Earth, the subsurface biosphere is truly vast, containing most of the prokaryotic diversity and biomass on our planet. Some investigations even point to an origin of life on Earth precisely deep in the subsurface. Therefore, the astrobiological implications of finally confirming the existence of liquid water habitats kilometers beneath the surface of Mars are truly exciting.”

–Statement by Alberto Fairén, a visiting interdisciplinary planetary scientist and astrobiologist within the department of astronomy at Cornell University, regarding a recent study reporting vast quantities of water may reside between 7 and 12 miles beneath the Martian surface. The study utilized data from NASA’s InSight lander.

Space Stories: More Quality Control Issues at Boeing, Blue Origin’s Planned Lunar Landing, and Citizen Scientists Assisting with Exoplanet Research

—NBC News: “NASA Inspector General Gives Damning Assessment of Boeing’s Quality Control in New Report“

The report, released Thursday by NASA’s Office of Inspector General, calls into question Boeing’s standards and quality control for its part in NASA’s efforts to return astronauts to the moon. In NASA’s development of its next-generation megarocket, known as the Space Launch System, it gave Boeing the contract to build the rocket system’s powerful upper stage. But according to the report, Boeing’s quality control systems fall short of NASA’s requirements, and some known deficiencies have gone unaddressed. What’s more, the workers on the project are not, as a whole, sufficiently experienced or well trained, according to the inspector general.

—Space News: “NASA Payload to Fly on First Blue Origin Lunar Lander Mission“

A NASA payload will hitch a ride to the moon on Blue Origin’s first lunar lander mission, scheduled to launch as soon as next March. In an Aug. 6 procurement filing, NASA revealed it selected Blue Origin to fly a camera system to study how engine plumes interact with regolith at south polar regions of the moon, collecting data to support future crewed landing missions. The payload, called Stereo Cameras for Lunar Plume Surface Studies (SCALPSS), will fly through NASA’s Commercial Lunar Payload Services (CLPS) program.

—NASA: “How NASA Citizen Science Fuels Future Exoplanet Research“

NASA’s upcoming flagship astrophysics missions, the Nancy Grace Roman Space Telescope and the Habitable Worlds Observatory, will study planets outside our solar system, known as exoplanets. Over 5,000 exoplanets have been confirmed to date — and given that scientists estimate at least one exoplanet exists for every star in the sky, the hunt has just begun. Exoplanet discoveries from Roman and the Habitable Worlds Observatory may not be made only by professional researchers, but also by interested members of the public, known as citizen scientists.

Audit Report: Concerns about the Gateway Space Station

In a recent audit report, Artemis Programs: NASA Should Document and Communicate Plans to Address Gateway’s Mass Risk, the Government Accountability Office (GAO) expressed some concerns about NASA’s Gateway space station, which will orbit the moon as part of Artemis IV . Specifically, the concerns relate to the first components of the space station to be launched in December 2027 —the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO).

In the report, GAO states:

The Gateway program’s projects—including PPE and HALO—made varying degrees of progress over the last year. However, the PPE and HALO projects face several significant challenges. For example, their combined mass is greater than their mass target. Mass is one of many factors that the program considers in its overall design. If they cannot meet their mass target, it may affect their ability to reach the correct lunar orbit.

The report goes on to state:

For example, program officials estimate that the mass of the lunar lander Starship is approximately 18 times greater than the value NASA used to develop the PPE’s controllability parameters.

NASA agrees with the single GAO recommendation in this report, which recommends that a mass management be ready for an upcoming review in September 2024.

There is a lot to read in the 52 page report, but the real question is whether NASA will be ready for the 2027 Gateway launch. This is a ongoing concern given that we are already seeing delays in other parts of the Artemis program.
