Queen’s Brian May and Bennu?

I was surprised to hear from Queen’s Brian May regarding the recent landing of the asteroid Bennu sample in the Utah desert. Here is what he posted and stated on his page:

“Today is the day – the long awaited day – when the sample of a piece of material From Bennu – the asteroid most likely to hit the Earth in the future, is recovered to Earth. This box when it is opened of material from the surface of Bennu can tell us untold secret of the origins of the universe, the origins or our planet and the origins of life itself. What an incredibly exciting day. Tune into Nasa TV. Go to the OSIRIS-REx website. Read my new book for the full story – Bennu 3-D – written with leader of the mission, Dante Lauretta. And enjoy this wonderful forward step in our knowledge of the universe.”

As you can see above, Brian May is named on the book about the asteroid. He is also credited with assisting NASA with the location of the sample landing. I was not aware of his deep involvement with the Bennu mission, or astronomy in general. In addition to the points above, it is worth noted that Mr. May (per Wikipedia):

  • earned a PhD degree in astrophysics from Imperial College London in 2007;
  • was a “science team collaborator” with NASA’s New Horizons Pluto mission;
  • is a co-founder of the awareness campaign Asteroid Day; and
  • has an asteroid named after him – Asteroid 52665 Brianmay.

Pretty impressive for a guy with a singing day job.

Space Missions: Good News for an Asteroid Sample, But Bad News for a Lunar Rover

First, let discuss the good news. The capsule carrying the sample material from the asteroid Bennu successfully landed in the Utah desert earlier today, as planned. NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission was a success. The space agency has plenty to celebrate.

And now for the bad news. India’s Chandrayaan-3 moon lander as well as its lunar rover were supposed to wake up around September 22 with the return of sunlight to the Moon’s South Pole. Unfortunately, neither craft showed any signs of coming back online. That said, the India space agency still has plenty to celebrate given its ability to successfully explore the South Pole before night set in.

Asteroid Sample Coming to Earth This Weekend

This weekend will should see the safe landing of a asteroid sample from far away. On Sunday, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft will return to Earth with sample material from asteroid Bennu, which it encountered two years ago.

Launched on Sept. 8, 2016, the spacecraft spent about two years getting to Bennu and then more than two years studying the asteroid and collecting a 250-gram sample that should be in the hands of NASA scientists shortly. The graphic below shows the return path of the sample as it heads for the Utah desert. You can also watch this NASA video for more information on the overall mission and keep abreast of mission highlights via this mission blog. NASA also has a recent podcast discussing the spacecraft’s adventures and trip back to Earth.

And what about OSIRIS-REx after it makes this deposit? It will become OSIRIS-APEX (APEX for “Apophis Explorer”) and go back into the inner solar system before encountering asteroid Apophis in 2029.

We talk about rocket reuse, but this is a terrific example of spacecraft reuse.

The timing could not be better as NASA awaits 2024 budget decisions from Congress and further discussions about another sample return, this one from Mars.

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.
