Q1. the Sun is dragging us around the galaxy at around 800,000km/h, taking around 250 million years to complete a single orbit.

That means our Solar System has made around 18 complete circuits since it was formed around 4.5 billion years ago.

Q2. The UAE has successfully launched several space missions in recent years. In September 2019, the country's first astronaut, Hazzaa Al Mansoori, completed an eight-day mission to the ISS, generating worldwide attention.

Q3. DubaiSat 1 (launched in 2009) DubaiSat 2 (launched in 2013) Al Yah 1 (launched in 2011) Al Yah 2 (launched in 2012)

Q4. The UAE launched the National Space Programme under which the UAE will prepare Emirati cadres specialised in airspace sciences. Young Emirati cadres will execute the National Space Programme. Launching the National Space Programme is part of the UAE’s ambitious space programme of reaching Mars by 2021 and building the first settlement there by 2117.

Main task: they measure the distance of an object in space from one part of the orbit, then six months later from exactly the opposite position in orbit (orbital diameter), they measure the distance of the object again and use the formula tehte= arc/radius to find the distance of the object.

So our solar system has taken around 18-20 orbits around the milky way 

Questions two : The UAE has successfully launched several space missions in recent years. A little less than two years down the line, this vision was accomplished as UAE's Hazza Al Mansouri made history and became the first Emirati astronaut to reach space.

Question 3 : Currently, the UAE operates 9 satellites 
here are some of them 
  • DubaiSat 1 (launched in 2009)
  • DubaiSat 2 (launched in 2013)
  • Al Yah 1 (launched in 2011)

  • Nayif-1 (launched in 2017)

Question 4 : The UAE is seeking opportunities to explore celestial bodies, develop satellite communications technology and deploy the latest space technologies in terrestrial applications. The UAE recognises the need for the applications of remote sensing through satellites, including natural resource mapping, environmental monitoring, land-use planning and security.
