Yesterday’s post highlighted the dangers involved in low-Earth orbit travel, while another earlier posting mentioned a book by Kelly and Zach Weinersmith who wrote “A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through?“

Well, the evidence continues to build on the difficulty of space travel and the need for greater study. This time its a report from The Guy Foundation in England, established by Geoffrey and Kate Guy to “facilitate exploration into quantum effects in biology and the role it could play in advancing medicine.” The 94-page report is titled The Health Hazards of Space Travel: Novel Insights from Quantum Biology.

You can read it this weekend at your leisure, but the bottom line is stated succinctly in the executive summary, further summarized here:

  • ...space travel seems likely to induce accelerated ageing in astronauts…associated with the disruption of cellular bioenergetics which could have other, perhaps more worrying health consequences.
  • …complex long-lived organisms, such as humans, will not be able to adapt to the unnatural environment of space, while shorter-lived, rapidly evolving ones, such as bacteria will.
  • At this stage, the following factors seem particularly significant…
    • zero gravity…;
    • {i}ncreased radiation…;
    • [t]he lack of a magnetic field…; and
    • [a] lack of near-infrared radiation.
  • Further experiments are urgently needed to improve our understanding of the underlying causes of space-induced ill health, and potential approaches to mitigate it.

The bottom line is that if we want to spread more than bacteria throughout the solar system and beyond, we need to get to work on these issues.

I am hoping Mr. Musk and friends are reading this before jumping off a cliff (or Earth in this case) with Mars-bound Starships. In fact, it may encourage Mr. Musk to use some of his funds to study these issues rather than play games with politics here are Earth. The $47 billion spent on Twitter would have gone a long way to help Mr. Musk achieve his dream of a Mars-based society, if that really is his dream.

NASA 2025 Calendar and More

If you are looking for a colorful calendar or simply some amazing images and art, you cannot go wrong downloading NASA’s 2025 calendar. For example, the graphics shown above and below are just two examples of the pages you can find in this 32-page calendar. It shows the number of NASA-led or supported space missions throughout our solar system. It is a numbing number of missions.

Have you heard of ESCAPADE mission, which stands for the Escape and Plasma Acceleration and Dynamics Explorers? Checking the NASA site, I learned that this mission was a dual-spacecraft mission to study ion and sputtered escape from Mars, and it was supposed to be launched this week but it was put back on the shelf. Here is more on the mission:

The planned launch on the Blue Origin New Glenn booster from Cape Canaveral, originally scheduled for October 13, 2024, has been delayed indefinitely. The science goals of the mission are to: understand the processes controlling the structure of Mars’ hybrid magnetosphere and how it guides ion flows; understand how energy and momentum are transported from the solar wind through Mars’ magnetosphere; and understand the processes controlling the flow of energy and matter into and out of the collisional atmosphere. EscaPADE is part of the NASA Small Innovative Missions for Planetary Exploration (SIMPLEx) program.

I am learning about it just in time to find out it is going nowhere for the moment.

Of course, there are many more on the list that you can look up for yourself. For instance, Google the European Space Agency’s BepiColombo.

NASA Looks to Rocketlab on Mars Sample Return

NASA is moving forward with planned studies to address the Mars Sample Return. Earlier in the week, NASA awarded a contract to Rocketlab for this very purpose.

Rocketlab announced the following:

…the Company has been selected by NASA to complete a study for retrieving rock samples from the Martian surface and bringing them to Earth for the first time. The mission would fulfill some of the highest priority solar system exploration goals for the science community – to revolutionize humanity’s understanding of Mars, potentially answer whether life ever existed on the Martian surface, and help prepare for the first human explorers to the Red Planet.

NASA’s Rapid Mission Design Studies for Mars Sample Return solicits industry proposals to carry out rapid studies of mission designs and mission elements capable of delivering samples collected by the Mars Perseverance rover from the surface of Mars to Earth. The results of this study will inform a potential update to NASA’s Mars Sample Return Program and may result in future procurements with industry. Rocket Lab’s study will explore a simplified, end-to-end mission concept that would be delivered for a fraction of the current projected program cost and completed several years earlier than the current expected sample return date in 2040.

This is just one of many studies expected to be conducted to find the best method for interplanetary rock retrieval.

Good luck to Rocketlab and the other involved in this endeavor.

Pic of the Week: The Launch of Hera

This week’s image shows a crowd in Germany watching the launch of the European Space Agency’s (ESA) Hera mission on October 7, 2024. The launch itself took place from Cape Canaveral Space Force Station in Florida via a SpaceX Falcon 9.

Hera’s goal is to study how binary asteroid systems like Didymos form and function to learn more about to defend the Earth from approaching asteroids. You may remember Didymos from the earlier NASA Double Asteroid Redirection Test (DART) mission.

Here is more from the ESA on the mission:

Hera’s first deep space manoeuvre will begin in late October and put the spacecraft on course for its next major milestone, a flyby of Mars in March 2025. During this flyby, Hera will use its instruments to study Deimos, the smaller and more enigmatic of Mars’s two moons. This will serve as an important test for many of the spacecraft’s instruments, ensuring they are fully operational before the spacecraft arrives at its final destination, Didymos.

Hera will perform a second deep space manoeuvre in February 2026. An ‘impulsive rendezvous’ in October 2026 will bring Hera into the vicinity of the Didymos asteroid system. The spacecraft will begin its detailed survey of the moonlet Dimorphos in 2027, which will turn the 151 m asteroid into one of the most studied objects in the Solar System.

Starship Stories: We Have Heard This Before

The other week, Elon Musk said he was planning to send five uncrewed Starship rockets to Mars in two years, followed by manned flights after that. Why the sudden announcement? It was not clear, but he does have money to burn and also a desire for attention.

In his Twitter/X posting, he said:

SpaceX plans to launch about five uncrewed Starships to Mars in two years.

If those all land safely, then crewed missions are possible in four years. If we encounter challenges, then the crewed missions will be postponed another two years.

Of course, he has yet to prove that the Starship is ready for assist NASA with the Artemis mission to place astronauts on the Moon. The rocket is getting better with every test, but the Starship problems are likely to delay the entire lunar mission. Yet he is already eyeing Mars?

If you read the full post, it appears he is using the Starship announcement to poke at California and Kamala Harris. He also seems to be ready to blame everyone but himself if he cannot meet his self-imposed Mars timetable.

One might ask if Mr. Musk has any idea where his Starship astronauts will be staying under this timetable. I have not heard of any great plans to build the necessary infrastructure to host a colony on the surface of Mars. Does he have a plan?

Mr. Musk had enormous problems meeting his proposed deadline for a Tesla pickup truck here on Earth, and the truck he eventually rolled out has has been less than a stellar vehicle given the hype. So any timetable on a Mars mission seems like mere fantasy at this point.

By the way, if Mr. Musk is so interested in protecting Earthlings from a dangerous future, he already has the ability to tamp down the rage and hate on Twitter/X and cease his calls for civil wars.

It is already in his power to make the Earth a better place to live while we plan for Mars. He just doesn’t seem to be all that interested.
