Astrobotic's history-making private lunar lander has experienced an anomaly on its way to the moon. The Peregrine moon lander launched early today on United Launch Alliance's debut Vulcan Centaur rocket, but it is experiencing an anomaly now that "if proven true, threatens the ability of the spacecraft to soft land on the Moon," Astrobotic says. Here's what we know.

Floating 'magic islands' on Saturn's moon Titan?

The floating "magic islands" of Saturn's largest moon, Titan, may finally have a scientific explanation. Scientists believe they're clumps of glacier-like snow shaped like honeycomb. The so-called islands were first spotted in 2014 by the Cassini-Huygens spacecraft as it peered through the orange haze surrounding Titan, which is a moon that's bigger than the planet Mercury.

A brand-new rocket just got its wings. United Launch Alliance's (ULA) Vulcan Centaur launched on its first-ever flight, called Cert-1, early this morning from Cape Canaveral Space Force Station in Florida. Atop the rocket was Pittsburgh-based company Astrobotic's Peregrine moon lander, which is carrying 20 different customer payloads, including five NASA science instruments and human remains for Celestis and Elysium Space.

DHL delivering Everest rock, 'meme' coin to the moon

(Astrobotic)

A rock from the top of Mount Everest, a tiny time capsule from Belgium, a physical "meme" coin, a collection of Reddit posts and a letter from a private astronaut who followed his father into space are now all being delivered to the moon. But it is not NASA nor any of the world's other space agencies that are shipping these items to the lunar surface.

Astronomers have figured out how some dying stars kick baby black holes out of the womb — and it's not pretty. Scientists modeled how black holes and neutron stars form after dying stars collapse, and explained why some get a hard 'kick' into interstellar space.

Water Softeners and Sizing: How to Choose the Right One for Your Home

Water hardness can make everyday tasks a hassle. It leaves soap scum on your shower walls, creates stubborn stains on your dishes, and dries out your skin and hair. The solution? A water softener. But with so many options available, figuring out the right size for your home can be tricky.

Grains of Hardness and Grain Capacity: Breaking Down the Essentials

Water hardness is measured in grains per gallon (GPG). The higher the GPG, the harder your water.

Typical hardness levels:
- Soft: 0-3 GPG
- Slightly hard: 3-6 GPG
- Moderately hard: 6-12 GPG
- Hard: 12-18 GPG
- Very hard: 18+ GPG

Water softeners have a grain capacity, which indicates how many grains of hardness they can remove before needing to regenerate.

Factors Affecting Water Softener Size

Several factors influence the size of water softener you need:

Number of people in your household: More people mean more water usage.
Average daily water consumption: This includes showering, laundry, dishwashing, and other water-related activities.
Water hardness level: The higher the hardness, the larger the softener you'll need.

How to Calculate Grain Capacity

Here's a general formula to estimate the grain capacity you need:

Number of people in household x Average daily water usage (gallons) x Water hardness (GPG) x 7 = Grain capacity

Example: A family of four uses 80 gallons of water per day, with a water hardness of 15 GPG.

4 x 80 x 15 x 7 = 33,600 grains

They would need a softener with a grain capacity of at least 33,600.

Common Size Recommendations:

1-2 people: 20,000-30,000 grains
3-4 people: 30,000-40,000 grains
5+ people: 40,000+ grains

Additional Considerations:

Iron content: If your water has high iron levels, you may need a larger softener.
Water usage patterns: If you have periods of high water usage (e.g., frequent guests, laundry days), consider a larger softener.
Space constraints: Ensure you have adequate space for the softener and its brine tank.

Consulting a Professional for Accurate Recommendations

For the most accurate sizing recommendations, consult a water treatment professional. They can test your water hardness and assess your specific needs.

Remember, choosing the right size water softener is essential for ensuring its effectiveness and efficiency. By understanding the factors involved and following these guidelines, you can select the perfect fit for your home.
