In Case You Missed It: Public Views on the Space Program

Back in July 2019, the Pew Research Institute issued the results of earlier surveys about the US space program. Let’s look at the answers to six of the questions:

  1. Most Americans think sending astronauts to Mars or the Moon should be a lower priority for NASA – or say it should not be done at all (see graphic below).
  2. Americans see priorities other than a Moon or Mars landing as more pressing for NASA.
  3. Half of Americans think space travel will become routine during the next 50 years of space exploration.
  4. A majority of Americans say the U.S. must remain a global leader in space exploration, and that NASA’s continued involvement is essential.
  5. Americans have little confidence that private space companies will minimize space debris. 
  6. Americans are not enthusiastic about the idea of creating a military Space Force.

NASA may not be listening given that a trip back to the Moon was the lowest priority of Americans and yet is it the largest program currently in the U.S. space program, with a Moon satellite and trip to Mars as part of future plans. As far as minimizing space debris, the public seemed right on the mark regarding private space companies. If Elon Musk is any indicator, the commercial sector will not be deterred as it adds thousands of new satellites and related debris. And the ship has sailed on the Space Force question with the creation of the US Space Force in December 2019.

This would not be the first time Washington, DC goes down its own path regardless of public sentiment.

Growing Options in Moon Dust

Speaking of moon dust, it seems scientists have found that they can grow plants in lunar soil. This is quite a surprise given the nature of moon dust. It would seem to be an even greater feat than growing plants in Martian soil.

NASA has reported that scientists at the University of Florida have successfully grown plants in actual lunar soil from the Apollo 11, 12, and 17 missions. Only water and a nutrient solution were added to the soil before seeds were planted. Plants started to sprout in two days. After 20 days the plants were harvested and studied before they had started to flower. While the lunar soil plants were somewhat stunted and stressed, the experiment was a success.

NASA noted:

This research opens the door not only to someday growing plants in habitats on the Moon, but to a wide range of additional questions. Can understanding which genes plants need to adjust to growing in regolith help us understand how to reduce the stressful nature of lunar soil? Are materials from different areas of the Moon more conducive to growing plants than others? Could studying lunar regolith help us understand more about the Mars regolith and potentially growing plants in that material as well? All of these are questions that the team hopes to study next, in support of the future astronauts traveling to the Moon.

This is a fascinating finding if it will allow us to use the lunar surface to feed astronauts rather than bringing more material from the Earth. It is also very timely as NASA is preparing the way for human habitation on the Moon under the Artemis Program.

We wanted to learn from the Moon before pushing onto Mars. This is a clear sign that we are doing so.

Space Quote: A Mature Rocket Market?

“The launch industry is at a point where the technology is so mature that it may not be necessary to have the U.S. government invest in it… It may be we’re at a tipping point with this rocket.”

-Statement by Dan Goldin, a former NASA administrator, regarding NASA’s expenditures on the Space Launch System (SLS) in a Wall Street Journal article, “NASA Is Building Moon Rockets, Maybe for the Last Time.” The SLS and Orion spacecraft are part of NASA’s Artemis Program to return astronauts to the Moon.

Do You Have Moon Dust in Your Portfolio?

With the drop in the stock market and fall of cryptocurrency, maybe it is time to expand the portfolio into some new areas. You can always consider moon dust, a small sample of which sold last month for about $500,000 when auctioned at Bonhams. The sample in question was from the Apollo 11 lunar mission

The auction house had this to say about the sample:

5 Scanning Electron Microscope (SEM) aluminum sample stubs, each topped with approximately 10 mm diameter carbon tape containing Apollo Moon dust, 4 of which with particles collected by Neil Armstrong, the first person to walk on the Moon, as part of the Apollo 11 contingency sample, July 21, 1969 and later removed by NASA from the Apollo 11 Contingency Sample Return Container (CSRC) Decontamination Bag; stubs hand numbered by NASA scientists in marker on bottom 2 through 6.

A “contingency sample” is basically an initial sample in case something happens during the mission that prevents the the full collection of material. But what is interesting here is that the contingency sample bag still contained some lunar dust when it was lost, and then it was caught up in a court case, and then sold at auction, and then inspected by NASA, who inappropriately removed the moon dust, which was eventually returned. The drama and incompetence of the US government in this case is almost worth the price of the dust. Hence, this is a unique substance in many ways, and it does make cryptocurrency sound pretty boring.

Just do not expect to see many lunar dust sales in the future. NASA is very protective of such material when it is not misplacing it.

Mars Sample Return: Do You Have Comments?

NASA and the European Space Agency are still looking for comments on the process to return Martian rock samples to Earth. Of the six steps needed to collect and return the samples (see graphic above), only the first step is currently underway with the Perseverance Rover exploring Mars. Now we need to get those samples home. You have until May 15th to get comments back to NASA on this.

And what is the time frame for getting these samples back to Earth? The current goal is 2033, assuming all goes well. You may recall that China also wants to collect and return Martian samples by 2030. I expect more delays on both sides. When you add this to the race back to the Moon, the space race is getting more interesting every day.
