Sarah al-Amiri: The woman leading UAE's Mars mission

19.07.2020

A dream was born when Sarah al-Amiri saw an image of the Andromeda Galaxy at the age of 12. In a region defined by turmoil, she never thought it would lead her country beyond Earth's stratosphere and toward Mars.

Over the past five years, the United Arab Emirates has sought to push the boundaries of science and technology.

In 2017, they announced the world's first Minister of Artificial Intelligence to spearhead the Gulf state's efforts in machine learning and other cutting-edge technologies.

That year, they also tapped a young Emirati engineer, Sarah al-Amiri, to lead the country's efforts into space at a time when the region was paying little attention to what is often described as the final frontier.

Dwarf planet Ceres is an 'ocean world' with sea water beneath surface, mission finds

Aug 10, 2020

The dwarf planet Ceres – long believed to be a barren space rock – is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday.

Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity, enabling the Nasa Dawn spacecraft to capture high-resolution images of its surface.

Now a team of scientists from the United States and Europe have analysed images relayed from the orbiter, captured about 35km (22 miles) from the asteroid.

They focused on the 20-million-year-old Occator crater and determined that there is an “extensive reservoir” of brine beneath its surface.

Several studies published on Monday in the journals Nature Astronomy, Nature Geoscience and Nature Communications also shed further light on the dwarf planet, which was discovered by the Italian polymath Giuseppe Piazzi in 1801.

Using infrared imaging, one team discovered the presence of the compound hydrohalite – a material common in sea ice but which until now had never been observed off of Earth.

Maria Cristina De Sanctis, from Rome’s Istituto Nazionale di Astrofisica said hydrohalite was a clear sign Ceres used to have sea water.

“We can now say that Ceres is a sort of ocean world, as are some of Saturn’s and Jupiter’s moons,” she told AFP.

Ocean underneath the crust seems to be so common - besides Ceres, we know of Europa and Ganymede, Enceladus, Titan and Pluto...

We're setting up 3 Canadian Space Division inside the RCAF. On par with 1 Canadian Air Division that has all the operational aviation assets.

It's good to see the CAF getting serious about the Space domain. Primary functions will be space domain awareness and surveillance. And coordination of space assets including provision of comms bandwidth on American satellites we've bought into, coordination of PNT services and tasking of imagery collection from commercial or allied assets.

Ottawa signs agreement with U.S. to send Canadian astronaut around the moon

A lunar milestone: Canada will send an astronaut around the moon in deal with U.S.

A Canadian will join Artemis II, a NASA-led mission that is set to fling a capsule carrying four astronauts around the moon and back

Following the flight around the Moon, Canada shall be the second country in the world to have its flag planted on the Moon directly by a human.

Yes, we beat the Soviets (and even their successors, Putin's Russia) on this one.

Not just that, but a Canadian astronaut would drop a maple leaf on the Moon to disprove any Moon landing conspiracies, just like when David Scott dropped a falcon feather (and a hammer) on the Moon during the Apollo 15 mission.

Both the feather and the hammer landed simultaneously
