Space Stories: New Lunar Water Estimates, Coronal Mass Ejection, and Oxygen on Mars

Here are some recent stories of interest.

—Southwest Research Institute: “New Findings Suggest Moon May Have Less Water Than Previously Thought“

A team recently calculated that most of the Moon’s permanently shadowed regions (PSRs) are at most around 3.4 billion years old and can contain relatively young deposits of water ice. Water resources are considered key for sustainable exploration of the Moon and beyond, but these findings suggest that current estimates for cold-trapped ices are too high.

—Scientific American: “Massive Sun Outburst Smacks NASA Spacecraft“

NASA’s Parker Solar Probe was built to withstand the ravages of the environment near our sun—and with good reason. The car-size spacecraft has now flown through a giant solar outburst of charged particles called a coronal mass ejection (CME). If that CME had it hit Earth instead, it may have caused vast, continent-wide blackouts, scientists say. Some of those searing particles whipped through space at about three million miles per hour.

—BGR: “NASA Successfully Generated Oxygen on Mars“

NASA’s Perseverance rover has done the unthinkable. Or, at least, a small device on the rover has. According to a tweet and article shared by NASA’s Perseverance team on Twitter, a device known only as MOXIE has proven that we can generate oxygen on Mars using the planet’s CO2-concentrated atmosphere. This tech is a huge boon, and the success of this story could help pave the way for future oxygen generation on the Red Planet, something that would make long-term exploration of the planet far more feasible.

Audit Results: SLS Program is Unaffordable

The Government Accountability Office (GAO) recently completed a review of NASA’s Space Launch System (SLS), which is the cornerstone of the Artemis program. GAO assessed the extent to which (1) NASA has established plans to measure the SLS program costs post-Artemis I, and (2) the program has made progress with its plans to reduce projected SLS costs.

The GAO report, Space Launch System: Cost Transparency Needed to Monitor Program Affordability, highlights a number of continuing issues related to project costs and budgeting.

So what is the bottom line? This quote is most concerning: “Senior NASA officials told GAO that at current cost levels, the SLS program is unaffordable.”

The SLS is the vehicle that is supposed to demonstrate our ability to return to the Moon as well as our readiness for a Mars mission. But all of this is contingent on continued funding from Congress, and the congressional auditors have raised a red flag.

I expect you could find similar audit issues with the earlier Apollo missions as well as other space missions, yet NASA does not need to give Congress a reason to put money elsewhere. Let’s hope NASA’s leaders take the audit seriously and show some progress to keep all of the parties happy and the funding alive.

The Pragyan Rover is Sleeping on the Moon

After a few weeks of work, India’s Pragyan rover on the Moon’s south pole was put to sleep last weekend to sit out the long lunar evening. It accomplished all of its goals, according to a Tweet from the Indian Space Research Organisation (ISRO):

We shall know in a few weeks whether the little lander is ready for more work.

Nature magazine noted some of the findings from the rover’s primary mission, including:

  • ions and electrons swirling near the lunar pole;
  • variations in soil temperature;
  • a moonquake; and
  • presence of sulfur and other elements.

Whatever happens, the Indian rover has been a great success.

The Moon Has One More Crater

If President Putin wanted to leave a mark, he has done so on the Moon. NASA’s Lunar Reconnaissance Orbiter (LRO) has apparently located the spot where the Luna-25 spacecraft crashed, as shown in the before and after shot above.

Given that craters can last for billions of years on the Moon’s surface, we can rest assured that the Russians have made an indelible mark on a distant land.

Russia, let’s call it a win and recall those troops from Ukraine.

By the way, maybe we should call the new crater Putin’s Sunset.

“…a comparison with India is illuminating: India’s economy was about half the size of Russia’s when the Berlin Wall came down in 1989. Today, India’s economy is 50 percent bigger than Russia’s. Forget about keeping pace with the United States: Russia can’t keep up with India.”

-Editorial in The Washington Post by David Von Drehle titled “India’s Brilliant Moon Landing Illuminates Russia’s Drastic Decline.” India’s steady progress on space missions, including Chandrayaan 2 back in 2019 (shown above), has occurred during Russia’s slow decline and current situation. This cannot be lost on Russia as its cosmonaut traveled to the International Space Station this weekend aboard an American rocket. Around the world, space programs are moving on without Russia, which was the leading nation at the start of the Space Age.
