Here are some recent space-related stories of interest.

—Forbes: “Astronauts Marooned On Moon Could Be Abandoned Under Current NASA Plan“

NASA’s working masterplan for the upcoming lunar landings has a fundamental flaw that could prove fatal to the first American astronauts set to touch down on the Moon in 2028, say experts at the NASA Office of Inspector General, an independent watchdog empowered by Congress to oversee the space agency. During the race to explore the south pole of the Moon, these inspectors say, “While NASA is taking steps to prevent catastrophic events from occurring during the Artemis [Moon] missions, at some point in the future, astronauts will likely encounter a life-threatening emergency in space.” But under NASA’s landing blueprints, they warn, “should the astronauts encounter a life-threatening emergency in space or on the lunar surface, NASA does not have the capability to rescue the stranded crew.”

—Fox35 Orlando: “NASA Cancels $73 Million Moon Lander Mission with Contractor Draper‘”

NASA has canceled a $73 million commercial lunar lander mission after years of delays and cost overruns, ending the project before the spacecraft ever launched. The agency and contractor Draper mutually agreed to terminate the Commercial Lunar Payload Services Task Order CP-12, a mission that began in 2022 and was intended to deliver scientific payloads to a crater near the moon’s south pole…NASA has already paid about $43 million under the contract and said those funds cannot be recovered because they were legally obligated under the agreement.

—CNN: “Pluto Flyby Mission Wakes Up After Long Sleep Nearly 6 billion Miles from Earth“

A groundbreaking mission that explored Pluto and distant solar system objects in unprecedented detail has awakened from its longest sleep ever — and it’s 5.9 billion miles (9.5 billion kilometers) from Earth. NASA’s New Horizons spacecraft went into a planned hibernation mode on August 7, 2025, and woke up on June 23 using commands stored on its main computer. The mission’s flight controllers at the Johns Hopkins University’s Applied Physics Laboratory in Laurel, Maryland, confirmed that New Horizons is in great shape and ready to transmit a stream of science data gathered during hibernation from its location in the region of icy objects known as the Kuiper Belt.

Study Findings: The Barnard’s Star Planetary System: Stability, Composition, and Evolution of Four Sub-Earth Exoplanets

Monthly Notices of the Royal Astronomical Society abstract of study findings:

Barnard’s Star is the nearest single star to the Sun (1.8 pc⁠⁠), and hosts four recently discovered planets. The star also has well-characterized stellar abundances of important rock-forming elements, including Fe, Mg, and Si. For refractory elements like these, the planets have likely inherited similar bulk elemental abundance ratios to the star, facilitating modelling of their interior structures. We present here an analysis of the Barnard’s Star planetary system on several fronts. We perform a detailed stability analysis of the system, ascertaining that all four planets likely have masses between 0.19 and 0.84 M⁠, and are likely tidally locked, whereas a 4:3 mean-motion resonance chain for the inner three planets cannot be ruled out. Using atmospheric evolution models, we show that the prospect of extant primary atmospheres is highly unlikely on any of the planets. Barnard’s Star’s abnormally high Mg/Si ratio and low Th/Mg ratio imply planetary mantles which (a) are rich in (Mg,Fe)O ferropericlase; (b) have less than half the water capacity as Earth; (c) generate about half of the radiogenic heating as Earth; and (d) are cool and unlikely to have outgassed secondary atmospheres. Our analysis of this system presents an accessible set of first steps for the study of other nearby exoplanetary systems, as well as sub-Earth planets which will be increasingly discovered over the coming years.

Sci-Fi Quote: Lt. Erica Ortegas and Strange New Worlds

Posted on by onespaceman2000

“I say that it’s not over, it’s never done, it’s never done. Because I always say the fans are the other half of what we do. So, I there’s a world for Ortegas that still exists, without giving anything away. She’s a character who I think was just a wonder to play. I’m so happy that they created the character in the first place. And as a pilot, as a maverick, as somebody who I have gotten to see has influenced so many younger fans, older fans, I keep saying it’s not over. There’s many places yet for Ortegas, and the world that she lives in to go.”

-Statement by Melissa Navia, who plays Lt. Erica Ortegas on Star Trek: Strange New Worlds, during an interview with Trekmovie. Season four of the Paramount+ series premieres on July 23rd. Filming for season five was completed late last year, with this final season of the series expected to be broadcast in 2027.

View of the Canadian Fires from Space

For those in the northeastern part of the United States, the impact of the ongoing Canadian fires is clear to see outside your window. A more distant view from a satellite (as shown above from earlier in the week) gives a better picture of what is occurring in Ontario and its impact on the surrounding region.

According to the latest data from the Canadian Interagency Forest Fire Centre (CIFFC), about 904 fires are currently burning across Canada, with 190 of the fires burning in Ontario.

Pic of the Week: Chinese Probe Captures Earth’s Quasi-Moon

This week’s image comes from a Chinese probe called Tianwen-2. It shows the spinning asteroid 2016 HO3, or Kamo‘oalewa, which is labeled by some of a “quasi-moon” of Earth until it decides to move on. Unlike the actual Moon, this asteroid is simply joining the Earth as it circles the Sun. The asteroid is about the size of a school bus.

The Chinese probe, launched from China in May 2025, is believed to have started its orbit of asteroid Kamo‘oalewa on June 6th of this year. It is now believed to be a rubble-pile asteroid, meaning it is basically loose material rather than a solid object. Even so, the Chinese probe may try to grab a sample to be returned to Earth in November 2027.

The source of the asteroid is still being debated, with some believing it is a piece of the Moon dislodged by an incoming asteroid while others believe it comes from the main asteroid belt.

In a paper released last year, scientists were leaning towards its origin being the main asteroid belt, noting:

Quantitative estimates show that population models of [Near Earth Asteroids] based on the migration of objects from the main belt are capable of accounting for Kamo‘oalewa-like objects. This relative contribution supports the hypothesis that (469219) Kamo‘oalewa originated from the main belt, which will be further investigated by future observations and in situ exploration of the Tianwen-2 spacecraft.

How long will it remain Earth’s partner? Back in 2021, Renu Malhotra, a UArizona planetary sciences professor, stated:

It will not remain in this particular orbit for very long, only about 300 years in the future, and we estimate that it arrived in this orbit about 500 years ago.
