NASA to make final attempt to contact Mars Opportunity Rover

WASHINGTON: US space agency NASA will make one final attempt to contact its Opportunity Rover on Mars late Tuesday, eight months after it last made contact.

The agency also said it would hold a briefing Wednesday, during which it will likely officially declare the end of the mission.

Opportunity landed on Mars in 2004 and covered 28 miles (45 kilometers) on the planet, securing its place in history after lasting well beyond its expected 90-day mission.

But a giant dust storm last year blocked sunlight from Mars, stopping Opportunity’s solar-powered batteries from being able to recharge.

Despite NASA engineers’ best efforts to get a response via radio channels, its last communication was on June 10, 2018.

In August, NASA caused an outcry after setting a 45-day deadline before it would declare “Oppy” dead. In October, it extended the deadline to January to reevaluate the situation.

China slams US ‘lies’ about Huawei-government ties

Published

on

BEIJING: Beijing on Friday accused the United States of spreading “lies” about Huawei after Secretary of State Mike Pompeo said the telecom giant was not being truthful about its ties to the Chinese government.
Huawei has been thrust at the centre of escalating tensions between the world’s two top economies, with President Donald Trump saying Thursday the fate of the company could be included in any deal to resolve their trade war.
Chinese foreign ministry spokesman Lu Kang said he was not aware of the “specifics” of Trump’s comments and repeated that dialogue must be based on “mutual respect”.
The Trump administration has infuriated Beijing by blacklisting the smartphone and telecommunications company over worries that China uses it as a tool for espionage and allegations of breaking Iran related sanctions.
Huawei has repeatedly denied that it works with the Communist-led government.
“To say that they don’t work with the Chinese government is a false statement,” Pompeo said.
Lu said US politicians have spread rumours about Huawei without providing evidence.

SpaceX launches first satellites of its internet network

Published

on

WASHINGTON: SpaceX on Thursday launched a rocket containing the first 60 satellites of its “Starlink” constellation, which is intended to provide internet from space and could one day number 12,000 satellites.

One of the company’s Falcon 9 rockets took off without incident from Cape Canaveral in Florida around 10:30 pm (0230 GMT).

The second stage of the rocket will begin to release them one hour after launch, at an altitude of 270 miles (440 kilometers), and then the satellites will use their thrusters to take up their places in a relatively low orbit of 340 miles (550 kilometers).

That’s slightly higher than the International Space Station, but well below the majority of terrestrial satellites, the highest of which sit in a geostationary orbit of 22,400 miles (36,000 kilometers).

The launch was originally scheduled for last week but was postponed, first due to high winds and then due to the need for a software update.

Billionaire Elon Musk’s firm, which is leading the private space race when it comes to rocket launches, is now looking to seize a chunk of the future space internet market.

The launch will make it an early forerunner, along with rival OneWeb, a startup, but well ahead of Amazon’s Project Kuiper, the brainchild of Musk’s space rival Jeff Bezos.

Each of the satellites weighs just 227 kilograms (500 pounds) and was built in-house in Redmond, near Seattle.

Starlink will become operational once 800 satellites have been activated, which will require a dozen more launches.
