It’s been the honor of a lifetime to help share this mission. I hope you carry this wonder with you.

@SirAlexas Atmospheric braking. The spacecraft will not be accelerating towards earth surface, but performing a careful descent maneuver by plunging into the atmosphere at 40,230 km/h but it will be decelerated as it plunges through the denser parts of the atmosphere and land at 32 km/h.

Re entry is tomorrow around 2.53am and by 3.07 they would have splashed at Pacific? Damn how fast is that rocket??...

@Astrophysicslad @IsolatedHavoc It has a 3:2 spin-orbit resonance. 3 days = 2 years. Partially tidally-locked.
English
@IsolatedHavoc Yes, it's tidally locked with the sun, therefore only one side faces the scorching sun while the other side undergoes freeze temp°(still a bizzare concept with such proximity to the sun though, jeez)
English
not that anybody asked, but despite being closest to the Sun, Mercury has ice.
guess why?

This poses the question.
Will future humans beings be genetically-engineered to adopt to thrive in the G cloud? Will their body composition be similar to ours?

A dense interstellar cloud with a significant high hydrogen would shrink our heliosphere to less than 1AU. Can cause depletion of the ozone layer and oxygen. Past extinction events on earth maybe related to a passage of our solar system through a dense interstellar cloud.
English
The REAL end of times.
Will the high dense G interstellar cloud make our planet inhabitable in the long-run?

However, the G cloud is about 30 times dense than the local interstellar cloud. Consequently, our heliosphere will be squashed, exposing the planets in the solar system to higher than normal exposure to cosmic rays.

Carbon-14 is a radioactive isotope.
Can be formed when galactic cosmic rays from distant stars interact with our atmosphere.
Some of the radioactive isotopes found in our oceans may indicate evidence of our solar system's past interstellar cloud passages.

What I know is that we have a companion stars, which were born in the same cluster now drifted apart like our sun and the HD161416 star
English
A number of stars in our Milky Way Galaxy actually belong to a separate galaxy that merged with the Milky Way.
For instance, the ESA Gaia telescope discovered Shiva & Shakti, two ancient stars believed to have been merged with the Milky Way Galaxy 12–13 billion years ago.

Below is an example of a hot blue star plowing through an interstellar cloud.
Our yellow-white star is going through a relatively less dense local interstellar cloud.

Our solar system oscillates up and down on the Milky Way's galactic plane every 60–70 million years. It oscillates roughly 100 light-years above and below it.

While oscillating the galactic plane, our solar system is steadily moving from its local interstellar cloud into the G cloud. This transition will roughly take 3,000 years to complete.
English
@Astrophysicslad Yes, in the craters on the poles in the permanently shadowed regions.
English
Scientific studies reveal that 2 to 3 million years ago, our solar system entered the dense cloud of cold gas and dust in the local cloud.
This may have triggered the influx of hydrogen atoms into Earth's atmosphere, forming noctilucent clouds and triggering the ice ages.

When the Sun's cycle is at solar maximum, most of the galactic cosmic rays (GCRs) from distant stars are pushed away by the intense Sun's magnetic field.
The reverse is true.
As of present, we're in a solar maximum.
Artemis II crew may have had a low exposure of the GCRs.
