UAE has joined China and the US in the race to the red planet by launching the first Arab space mission to Mars.UAE has successfully launched an H2-A rocket from Tanegashima spaceport, Japan at 6:58 am Japanese time on Monday (July 20, 2020) Just over an hour after launch, the probe deployed solar panels to power its systems and establish radio communication with the mission on earth. The journey was initially due to launch on July 14 but delayed by bad weather. The unmanned probe is called “Al-Amal” or “Hope”. As a result of the announcement of the mission in 2014, the UAE launched a National Space program in 2017 to develop local expertise. Mohammed Bin Rashid Space Centre (MBRSC), the space center of Emiratis and Dubai, worked with US educational institutions to improve and build the Hope Probe. The United Arab Emirates strives to develop its scientific and technological capabilities and reduce its reliance on oil. The mission has caused $200m, confirmed by the Minister for Advanced Sciences, Sarah Amiri. Hope will reach the orbit of Mars by February 2021, marking the 50th anniversary of the UAE. It's a long journey of seven months (taking advantage of a period when the Earth and Mars are nearest) or 494 million km at an average speed of 121,000kph and the spacecraft will be observed by The MBRSC space center in Dubai. It will orbit the planet for a whole Martian year (687 days) and will provide a complete picture of the atmosphere for the first time, studying daily and seasonal changes. Amiri said, “This is the future of the UAE,” who is also minister of state for advanced sciences, told Dubai TV from the launch site. It has an ambitious plan for a Mars settlement by 2117.
Comet C/2020 F3' which is also called NEOWISE comet is considering the brightest comet of the last few decades that we can see with our naked eyes from the earth. Comets are made of ice, rock & dust. Comets were created by the frozen leftovers when the solar system form, roughly 4.6 billion years ago. The NEOWISE comet first discovers on March 27, 2020, by NASA's astronomers. The name NEOWISE came from the short name of the telescope that discovered this(Telescope Name: Near-Earth Object Wide-field Infrared Survey Explorer telescope). Oort cloud is a spherical shell that surrounds everything of our solar system. It is made of icy pieces of space debris. The outer limit of the Oort cloud defines the cosmographical boundary of the solar system and comets that take more than 200 years to complete it's one lap around the sun, originate from the Oort cloud. The NEOWISE comet takes 6,800 years to complete one lap around its orbit. It comes from the Oort cloud. On July 22-23, this comet will pass the earth at a distance of 103 million kilometres. People living across Northern Hemisphere will be able to see it with naked eyes after sunset. This comet is considering the brightest comet of the last few decades because, at the starting of July, it crossed the Sun from a very close distance. Because of the sun's extreme heat, the outer layer of the comet released a huge portion of gas & dust which created a wide bright atmosphere around the comet that is called 'Coma'.The comet has another unique property. It has two tails. One is a dust tail & the other is gas tail. The comet's dust tail has whitish colour because its particles easily reflect sunlight. The other gas tail is slightly narrower than the main tail & has a faint blue colour. The brightness and its unique properties make this comet the rarest comet of the last few decades. The last comet that was bright like NEOWISE was Hale-Bopp comet. It was last seen in 1995-1996.
