Space Mission: Saudi Arabians to Visit the International Space Station

While the Biden Administration appears to have its issues with Saudi Arabia, this is not stopping the visit of two Saudi Arabian private astronauts to the International Space Station (ISS). Space News reports that NASA has confirmed that a male and female astronaut from Saudi Arabia will travel to the ISS next spring aboard a SpaceX rocket as part of the privately-run Axiom Space. Plans for this mission were reported back in September.

This will be the second Axiom Space mission to the ISS. Other missions are being planned involving additional countries, including astronauts from Turkey, Hungary, Canada, and the United Arab Emirates. Mission participants need to be approved by a NASA-chaired panel that includes the countries involved with the ISS program.

Axiom Space will send four crew members to the ISS for 12 days. Here is the pitch for the second mission, or Ax-2:

The Axiom Mission 2 (Ax-2) astronauts are part of the latest class of space explorers and Axiom’s next crew to advance a new method of access to the International Space Station (ISS) and low-Earth orbit. Aboard the orbiting laboratory, the four-person, multinational crew will conduct extensive research, investigate novel technologies, and engage with audiences around the world as champions of science, technology, engineering, mathematics, and the arts. Their efforts will continue to lay the groundwork and establish key capabilities for the future Axiom Station, the world’s first commercial space station.  

You may recall that Saudi Arabia also signed onto the Artemis Accords over the summer. The Accords were established in 2020 to affirm each signatory’s commitment to sustainable space exploration “guided by a common set of principles that promote the beneficial use of space for all of humanity.”

All of this shows that space still remains a realm that does not need to be militarized or abused even if we have yet to figure out to resolve these issues here on Earth. Whatever problems with have with our neighbors, it’s good to see we are building some things together.

As noted earlier, even if the press on this Ax-2 mission demonstrates some unity, let’s just hope these “astronauts” are there for more than a joy ride. I am not convinced that space tourism is what we need. But given that Axiom Space is considering its own commercial space station, maybe there is some interest in real work in space by these parties.

Space Mission: ESA’s Euclid Telescope

To follow up on the previous post, Russia also lost out on launching the European Space Agency’s (ESA) Euclid spacecraft. Russia was supposed to launch it on a Soyuz-ST/Fregat rocket this December, but the country’s invasion of Ukraine led to a change in plans. SpaceX will now be launching the spacecraft next year.

Euclid was designed to study dark energy and dark matter, and make a 3D-map of the Universe. The project includes scientists from 14 countries: Austria, Denmark, France, Finland, Germany, Italy, Netherlands, Norway, Spain, Switzerland, Portugal, Romania, the UK, and the US.

Euclid hopes to answer the following questions:

  • How did the Universe originate? What were the conditions just after the Big Bang, and how did these give rise to the large-scale structures we see today?
  • Why is the Universe expanding at an accelerating rate today?
  • Is dark energy – a term often used to signify the mysterious force behind this cosmic acceleration – real? If so, is it a constant energy density intrinsic to and spread throughout space, or a new force of nature that slowly evolves as the Universe expands?
  • What is the nature of dark matter, and how do neutrinos possibly contribute? Are there other as-yet-undetected massive particles in the Universe?

Once launched, Euclid will operate in the Sun-Earth Lagrange point 2 (L2), which is where the James Webb Space Telescope is located as well as ESA’s Gaia spacecraft. Gaia, launched in December 2013, is currently mapping the stars in the Milky Way galaxy. It seems L2 is the place to be.

NASA is contributing infrared flight detectors for one of Euclid’s two science instruments. You can read more about the NASA contribution here.

Space Mission: Preparing for a Launch to Europa in 2024

Earlier this year, NASA’s Jet Propulsion Laboratory started assembling the Europa Clipper spacecraft so it is ready for its launch in 2024 (you can find the latest update here). Once it arrives at Jupiter, the spacecraft will have at least 50 flybys to study the Jovian moon and learn more about its inside, outside, and atmosphere.

Why Europa? NASA explains it this way:

Extraterrestrial life might exist under all sorts of conditions that humans would struggle to imagine. But we know of one set of conditions in which life flourishes in a multitude of shapes and sizes: the conditions found on Earth. Because we know Earth has the right conditions for life, humans can then sharply narrow down the search for extraterrestrial life by searching only in places that have the conditions that Earth life requires: a source of energy, the presence of certain chemical compounds, and temperatures that allow liquid water to exist. Jupiter’s icy moon Europa seems to be just such a place.

And water exists in abundance, as the NASA graphic shows below.

The Europa Clipper will not make it to Jupiter until 2030, so we have a long wait ahead of us. It also gives us plenty of time to guess about what we will find.

Space Mission: A Trip to the Oort Cloud?

While NASA does not have any plans to send a specific missions to study the Oort Cloud, the most distant region in our solar system containing trillions of frozen objects, it has already sent five spacecraft in that direction. Two Voyager spacecraft, two Pioneer spacecraft, and the New Horizons spacecraft are all heading that way, but it is quite a distant.

For example, the Voyager spacecraft will not hit the Oort Cloud for another 300 years and will continue to travel through the cloud for another 30,000 years before escaping the solar system. As a result, all of these spacecraft will be dead as a rock before ever hitting that region and of no use to anyone back here, yet they will still carry messages from all of us to the stars. So in that sense, they still have a mission to perform should anyone be out there.

The Oort Cloud is still a theory since it has not been observed, but there is plenty evidence regarding its existence, including the comets that come into the center of our solar system from that region. The cloud itself is believed to be a sphere rather than on the same plane as the planets, so it forms a protective ring around the planets potentially becoming a hazard to any incoming or outgoing spacecraft. What this will mean for interstellar space travel, should that day come, is anyone’s guess at this point.
