Nasa said on Friday it will send a small helicopter to Mars as part of the US space agency's 2020 mission to place a next-generation rover on the Martian surface, marking the first time such an aircraft will be used on another world.
The remote-controlled Mars Helicopter, designed to take flight in the thin Martian atmosphere with twin counter-rotating blades, weighs about 1.8 kilograms, Nasa said. Its blades will spin at almost 3,000rpm, about 10 times the rate employed by helicopters on Earth.
"The altitude record for a helicopter flying here on Earth is about 40,000 feet (12,200 metres). The atmosphere of Mars is only one per cent that of Earth, so when our helicopter is on the Martian surface, it's already at the Earth equivalent of 100,000 feet (30,480 metres) up," Mimi Aung, the Mars Helicopter project manager at Nasa's Jet Propulsion Laboratory, said in a statement.
Nasa officials said the craft will reach the Red Planet's surface attached to the car-sized rover. After placing the helicopter on the ground, the rover will be directed to drive to a safe distance to relay commands. Controllers on Earth will command the helicopter to take its first autonomous flight after its batteries are charged and tests are conducted, Nasa said.

"The idea of a helicopter flying the skies of another planet is thrilling," Nasa administrator Jim Bridenstine said in a statement.
The helicopter is intended to demonstrate the viability and usefulness of such craft on Mars, Nasa said, with potential roles as a low-flying scout or to reach locations inaccessible from the ground.
The Mars 2020 rover mission is scheduled to launch in July of that year from Cape Canaveral Air Force Station in Florida and reach Mars in February 2021. The rover is designed to carry out geological studies and ascertain the habitability of the Martian environment, Nassa said.

Will the pound fall to parity with the dollar?
The idea of pound parity now seems less far-fetched as the risk grows that Britain may split away from the European Union without a deal.
Rupert Harrison, a fund manager at BlackRock, sees the risk of it falling to trade level with the dollar on a no-deal Brexit. The view echoes Morgan Stanley’s recent forecast that the currency can plunge toward $1 (Dh3.67) on such an outcome. That isn’t the majority view yet – a Bloomberg survey this month estimated the pound will slide to $1.10 should the UK exit the bloc without an agreement.
New Prime Minister Boris Johnson has repeatedly said that Britain will leave the EU on the October 31 deadline with or without an agreement, fuelling concern the nation is headed for a disorderly departure and fanning pessimism toward the pound. Sterling has fallen more than 7 per cent in the past three months, the worst performance among major developed-market currencies.
“The pound is at a much lower level now but I still think a no-deal exit would lead to significant volatility and we could be testing parity on a really bad outcome,” said Mr Harrison, who manages more than $10 billion in assets at BlackRock. “We will see this game of chicken continue through August and that’s likely negative for sterling,” he said about the deadlocked Brexit talks.
The pound fell 0.8 per cent to $1.2033 on Friday, its weakest closing level since the 1980s, after a report on the second quarter showed the UK economy shrank for the first time in six years. The data means it is likely the Bank of England will cut interest rates, according to Mizuho Bank.
The BOE said in November that the currency could fall even below $1 in an analysis on possible worst-case Brexit scenarios. Options-based calculations showed around a 6.4 per cent chance of pound-dollar parity in the next one year, markedly higher than 0.2 per cent in early March when prospects of a no-deal outcome were seemingly off the table.

WHAT IS A BLACK HOLE?
1. Black holes are objects whose gravity is so strong not even light can escape their pull
2. They can be created when massive stars collapse under their own weight
3. Large black holes can also be formed when smaller ones collide and merge
4. The biggest black holes lurk at the centre of many galaxies, including our own
5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.
