UAE astronaut exits ISS for first Arab space walk
Friday, 28 April 2023 14:26 Write a comment
Emirati astronaut Sultan Alneyadi stepped out of the International Space Station (ISS) Friday for the first space walk by an Arab astronaut, a moment touted by the UAE as a "milestone".
Alneyadi, 41, dubbed the "Sultan of Space" by his alma mater, become the first Arab astronaut to embark on a six-month space mission when he blasted off for the ISS in early March aboard a SpaceX Falcon 9 rocket.
On Friday, he undertook "the first Arab spacewalk in history," wearing a space suit that bears the Emirati flag, said the United Arab Emirates' Mohammed bin Rashid Space Centre (MBRSC), calling it "a new historic milestone".
Footage live-streamed by NASA showed the UAE astronaut exiting an ISS hatch.
"Sultan Alneyadi has egressed the hatch, the first ever space walk by an Arab astronaut," NASA said.
The space walk will last for around six hours and thirty minutes, according to MBRSC and NASA.
Alongside NASA's Stephen Bowen, Alneyadi will "change the Radio Frequency Group unit and prepare for the installation of solar panels," the Emirati astronaut said in a Twitter post carried by the official WAM news agency.

The European Space Agency (ESA) is currently training five astronaut candidates for future missions to the International Space Station and beyond. Their training programme consists of three phases: The first phase is basic training, which covers medical exams, fitness assessments, and space programmes and systems. The second phase, the pre-assignment training, is advanced training in specific areas such as systems training, vehicle training, robotics and EVA-training. The third phase is mission-specific training, which is tailored to the tasks and experiments that astronauts will perform during their mission. ESA's astronaut training programme also includes training for exploration of
Asteroid's comet-like tail is not made of dust, solar observatories reveal

A weird asteroid has just gotten a little weirder.
We have known for a while that asteroid 3200 Phaethon acts like a comet. It brightens and forms a tail when it's near the Sun, and it is the source of the annual Geminid meteor shower, even though comets are responsible for most meteor showers. Scientists had blamed Phaethon's comet-like behavior on dust escaping from the asteroid as it's Pentagon leaks suggest China developing ways to attack satellites
