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.

U.S. experiment on Beresheet might have survived crash

Scientists for Lunar Reconnaissance Orbiter (LRO) have revealed that the small U.S. experiment on Beresheet might have survived the spacecraft’s crash onto the lunar surface.

The NASA payload, known as the Lunar Retroreflector Array (LRA), is a technology demonstration composed of eight mirrors made of quartz cube corners that are set into a dome-shaped aluminum frame. These mirrors are intended to serve as markers for other spacecraft, which can use them to orient themselves for precision landings. The entire instrument is smaller than a computer mouse and lightweight. But it’s tough, radiation-hardened and designed to be long-lived, so the LRA may not have been destroyed by Beresheet’s hard landing.

“Yes, we believe the laser reflector array would have survived the crash, although it may have separated from the main spacecraft body,” said David Smith of the Massachusetts Institute of Technology, principal investigator of the Lunar Orbiter Laser Altimeter (LOLA) instrument aboard NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft.

“Of course, we do not know the orientation of the array,” Smith, who’s also an emeritus researcher at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, told Inside Outer Space. “It could be upside down, but it has a 120-degree angle of reception, and we only need 1 of the 0.5-inch cubes for detection. But it has certainly not made it any easier.”

They are going to use LOLA to try to find LRA. If they get a reflection, that experiment will essentially be a success, despite Beresheet’s failure.

    “… quartz cube corners that are set into a dome-shaped aluminum frame”.
    whoa … going to have to check out the quartz cube corner deal.
    Quartz cube corner ?

    >Cubic or Pseudocubic Habit, Cube Quartz or “Würfelquarz”.<

    Pardon me. I come from the 'natural' (quartz and other) crystal growth end.
    'Pulling' crystal from a molten melt is another subject altogether.
    Or, as growing from the 'Skull' method as Cubic Zircon.

    I hope these "mirrors" do the job however they were fabricated.

    Is the equipment listed at the beginning of this wiki article ? Cool little optical devices.

    Further in the article; after noting cats eyes, bicycle reflectors etc; they mention the Apollo and Soviet retrorefletors left on the moon. The article states that returns are very low (single photon) and make detection difficult.
