2020 Oct 18 Planet Mars at Post-Opposition

A close-up view of Mars from Brunei Darussalam tonight, October 18, 2020 – after a week from opposition and closest to Earth, the red planet is still best viewable in the night sky.

One of the prominent low albedo (dark) feature is Syrtis Major Planum, clearly visible on this photograph. Albedo is a measure of how much light something reflects.

NASA Invites Public to Submit Names to Fly Aboard Next Mars Rover

NASA – Although it will be years before the first humans set foot on Mars, NASA is giving the public an opportunity to send their names โ€” stenciled on chips โ€” to the Red Planet with NASA’s Mars 2020 rover, which represents the initial leg of humanityโ€™s first round trip to another planet. The rover is scheduled to launch as early as July 2020, with the spacecraft expected to touch down on Mars in February 2021.

UAE plans unmanned mission to Mars by 2021

(Reuters) – The United Arab Emirates said on Wednesday it planned to send an unmanned probe to Mars by 2021, in the Arab worldโ€™s first mission to another planet.

A UAE Space Agency will be set up to supervise the mission and develop a space technology industry in the country, a government statement said. It did not give details such as the cost of the probe or how it would be designed and built.

โ€œThe UAE Mars probe represents the Islamic worldโ€™s entry into the era of space exploration. We will prove that we are capable of delivering new scientific contributions to humanity,โ€ said UAE President Sheikh Khalifa bin Zayed al-Nahayan.

With a population estimated at no more than about 8 million, most of whom are foreign workers, the UAE lacks the scientific and industrial base of the big spacefaring nations.

But it is keen to diversify its economy beyond oil into high-technology sectors, and its oil reserves give it immense financial power that it could use to buy expertise. One of the sovereign wealth funds of Abu Dhabi, the biggest emirate, is estimated to have assets worth nearly $800 billion.

The UAE’s fast-growing airlines, Emirates and Etihad, are among the world’s biggest buyers of planes from U.S. and European aerospace firms, and a factory in the Abu Dhabi desert now turns out sophisticated parts for Airbus.

The UAE has invested over $5.4 billion in satellite ventures such as data and television broadcast company Al Yah Satellite Communications, mobile communications firm Thuraya and earth mapping and observation firm Dubai Sat, the government said.

The Mars probe will take nine months to complete the more than 60 million-kilometer (37.5 million-mile) journey to Mars, and will make the UAE one of only nine countries with space programs exploring the Red Planet, the statement said.

Bandar Seri Begawan – Look west in twilight on February 20 and 21 as two planets, Venus andย  Mars,ย appear close one another in the sky and will be accompanied by the thin moon crescent. The celestial phenomenaย  known asย conjunctions occur when celestial bodies have the same right ascension or the same ecliptic longitude as seen from the Earth. While it would be very low in the twilight sky, it might be an interesting photo opportunity. ย Venus will beย shining bright in the west after sunset and sky gazers can locate Mars as they are separated within 1 degree apart.ย If the weather cooperates, it could be a spectacular image.
