UAE astronaut Sultan Al Neyadi has asked people to explain a rare physics event that took place on the International Space Station.
He was seen spinning an iPad three times but on the last spin the device rotated in different directions as opposed to the constant movement on the first two occasions.
Dr Al Neyadi, 41, demonstrated the intermediate axis theorem in space, also known as the Dzhanibekov effect or the Tennis Racket Theorem, which was discovered by Soviet cosmonaut Vladimir Dzhanibekov on the MIR space station in 1985.
"This question is for the smart ones," he said in a video posted on his Twitter on Monday. "An object's movement is as shown in these three cases.
"Have you noticed that in the third case, the direction of movement kept on changing unlike the first two cases where the direction remained the same. Can you tell me why?"
The theory states that objects, except for ones that are circular and square, have two axes and when that object rotates, it spins in a stable condition.
But when the rotation happens around the intermediate axis, it is unstable, causing it to spin in a different direction than expected.
And when this is done in microgravity, the physics phenomenon is even more fascinating.
Dr Al Neyadi arrived on the ISS on March 3 for a six-month stay and has already begun some of the 219 science experiments assigned to him by Nasa and UAE universities.
He harvested tomatoes that were planted by a Nasa astronaut in December, as part of a botany investigation and also for crew consumption.
Fresh supplies are being sent on Wednesday on a SpaceX cargo resupply mission, which will deliver experiments, food and other items to the new astronauts on board.
There were 11 people on the ISS, but four departed this weekend and landed safely back on Earth.
Crew members include station commander Sergey Prokopyev, flight engineer Dmitri Petelin, both from Roscosmos, and Nasa flight engineer Frank Rubio.
They were supposed to return to Earth last month but the Soyuz spacecraft on which they had arrived suffered severe damage from a micrometeorite.
A replacement Soyuz was sent and will bring the astronauts back home in September.
This means the crew will complete a year in space and replacements will be sent as they return.
On May 12, four private astronauts, including two from Saudi Arabia, will travel to the ISS for a 10-day stay.
The Axiom-2 mission will lift off on a SpaceX Falcon 9 rocket from the Kennedy Space Centre in Florida.
The Saudi astronauts are Ali Al Qarni and Rayyanah Barnawi, who is set to become the first Arab woman in space.
This will bring the number of Arabs in space together simultaneously to a record of three.

WHAT ARE NFTs?
Non-fungible tokens (NFTs) are tokens that represent ownership of unique items. They allow the tokenisation of things such as art, collectibles and even real estate.
An NFT can have only one official owner at one time. And since they're minted and secured on the Ethereum blockchain, no one can modify the record of ownership, not even copy-paste it into a new one.
This means NFTs are not interchangeable and cannot be exchanged with other items. In contrast, fungible items, such as fiat currencies, can be exchanged because their value defines them rather than their unique properties.

Evacuations to France hit by controversy
- Over 500 Gazans have been evacuated to France since November 2023
- Evacuations were paused after a student already in France posted anti-Semitic content and was subsequently expelled to Qatar
- The Foreign Ministry launched a review to determine how authorities failed to detect the posts before her entry
- Artists and researchers fall under a programme called Pause that began in 2017
- It has benefited more than 700 people from 44 countries, including Syria, Turkey, Iran, and Sudan
- Since the start of the Gaza war, it has also included 45 Gazan beneficiaries
- Unlike students, they are allowed to bring their families to France
