Rice is one of the world's staple crops. It is regularly eaten by more than half the world's population. And now, it's been grown in microgravity, on board the newly launched Chinese Wentian space laboratory.

Wentian launched in July and joined up with the Tianhe module of China's new space station. Its original complement of eight experiments included one that attempted to grow rice in microgravity.

Rice typically grows to 3 to 4 feet over four months, and the stalks on Wentian have not been able to complete their entire maturation cycle since the experiment started in July. However, they seem to be on track compared to their Earth-bound counterparts.

There were actually two types of rice launched as part of the experiment. A tall shoot variety reached almost 30 centimeters in the first month of growth, and a dwarf variety reached around 5 cm. Both of these growth amounts are on par for these particular rice varieties on Earth.

While hundreds of thousands of people made their way to the Space Coast two weekends in a row for a shot to see the most powerful rocket to ever lift off from Earth, a couple of scrubs for NASA's Artemis I mission left them disappointed.

But for those who were making a weekend out of their efforts, there was at least one rocket that lit up the sky for those who hung around.

SpaceX has continued its frenetic pace of Falcon 9 launches including a couple of Starlink missions that took flight: one right before midnight last weekend on Aug. 27, about 32 hours before NASA called off its first Artemis I attempt; and then again Sunday night about 32 hours after NASA was aiming for its second try to send up its Space Launch System rocket with the Orion capsule to the moon.

So while NASA may eventually have to roll back the Artemis I hardware capable of 8.8 million pounds of thrust on liftoff to the Vehicle Assembly Building, SpaceX keeps sending up its 1.7 million pounds of thrust servings.

Reusable rocket engines have become all the rage lately, even as NASA's continually delayed Artemis I mission attempts to launch with non-reusable technology. Realistically, the only way to significantly lower launch costs is to reuse the engines rather than build them from scratch every time. Another small start-up company, RocketLab, has successfully retested a rocket that has flown in space.

SpaceX famously has flown several of its Raptor engines into space multiple times already, making headlines along the way. But it's not the only company with ambitions for reusing its rockets. RocketLab, which makes a much smaller rocket called the Electron, has also been eyeing this milestone for a while now.

The company made headlines back in May when it made a spectacular show of catching its rocket stage out of the air with a helicopter.
