Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

 
Unfortunately, that is exactly where that journey takes him.

 
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

 
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

The atomic hydrogen in Mars’ atmosphere

Atomic hydrogen in Mars' atmosphere, as seen by Al-Amal

The two photos to the right, cropped and reduced to post here, were taken by the ultraviolet spectrometer on the UAE Mars orbiter Al-Amal (“Hope” in English) on April 24 and April 25.

During the 10 hours 34 minutes between the images, the Hope probe moved from being over the planet near noon and viewing the entire dayside (top) to being over the planet at dusk and seeing both the day and night side (bottom). These images will be used to reconstruct the 3D distribution of hydrogen and learn more about its production through the process of splitting water molecules by sunlight and its eventual escape to space.

This data will eventually allow scientists to more precisely measure the total water loss to space that Mars’ experiences annually, which will also allow them to determine approximately how much water the planet has lost over the eons.

    Looks like an extra-solar world there. Juno made Jupiter look like an unfamiliar brown dwarf.

    Congratulations UAE. This is great information.
    Here’s to UAE becoming the Elon Musk of the Middle East.
