In an interplanetary first, NASA to fly a helicopter on Mars as part of 2020 mission

California :NASA said 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 four pounds (1.8 kilograms), with a fuselage the size of a softball, NASA said. Its blades will spin at almost 3,000 rpm, roughly 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 meters). The atmosphere of Mars is only one percent 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 meters) up,” Mimi Aung, the Mars Helicopter project manager at NASA’s Jet Propulsion Laboratory, said in a statement.

 

NASA officials said the rotorcraft 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 aircraft on Mars, NASA said, with potential roles as a low-flying scout or to reach locations inaccessible from the ground.

NASA said it plans a 30-day flight test period that will include up to five flights, starting with a short vertical jaunt to hover for about 30 seconds at an altitude of 10 feet (3 meters) and progressing to flight distances up to a few hundred yards and durations up to 90 seconds.

The helicopter contains solar cells to charge its lithium-ion batteries and a heating mechanism to keep it warm during frigid nights.

The Mars 2020 rover mission is scheduled to launch in July 2020 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, NASA said.

JNU sedition: Court questions chargesheet without sanction

Agencies

New Delhi: A court here questioned Delhi Police on Saturday for filing a chargesheet against former Jawaharlal Nehru University Students’ Union (JNUSU) president Kanhaiya Kumar and others in the 2016 JNU sedition case without procuring the requisite sanctions.

The police told Metropolitan Magistrate Deepak Sherawat they would procure the required sanctions within 10 days.

“Why did you file (the chargesheet) without approval? You don’t have a legal department,” the court said.

 

The court is likely to resume hearing on the matter soon.

Delhi Police had on January 14 filed the chargesheet at a city court against Kumar and others, saying he was leading a procession and supported seditious slogans raised on the university campus during an event in February 2016.

Police also charged former JNU students Umar Khalid and Anirban Bhattacharya with allegedly shouting anti-India slogans during the event held on February 9, 2016, to commemorate the hanging of Parliament-attack mastermind Afzal Guru. PTI

Volcano waiting to erupt in Cong-JD(S) alliance : Yeddyurappa

Agencies

Published

on

Bengaluru: Karnataka BJP president BS Yeddyurappa has said some Congress MLAs skipping the Congress Legislature Party (CLP) meeting and the deep differences between the ruling coalition partners are an indication that a volcano may erupt in the coming days.

His remarks came after four dissident Congress MLAs skipped the CLP meeting here that was called as a show of strength against an alleged bid by the BJP to dislodge the HD Kumaraswamy-led Congress-Janata Dal (Secular) government.

“The absence of Congress MLAs from the CLP meeting and deep differences between the coalition partners are an indication that this is likely to erupt as a volcano in the coming days,” Yeddyurappa said on Friday evening here.

 

Their absence also showed intense and widespread anger and resentment among Congress MLAs, he said.

The BJP chief said the tone of CLP leader Siddaramaiah’s warning to the party MLAs showed his frustration and fear.

“ Siddaramaiah, the tone, tenor and content of the meeting notice given by you to the MLAs shows your frustration and proves that you are gripped by fear. If your relationship with the MLAs was strong and cordial, why did you mention in the notice that action would be taken as per the anti-defection law?” Yeddyurappa asked.

The Congress would issue notices to absentee MLAs–Ramesh Jarkiholi, B Nagendra, Umesh Jadhav and Mahesh Kumatahalli, Siddaramaiah had told reporters after Friday’s meeting.

Yeddyurappa also attacked Congress general secretary KC Venugopal over his remarks that ‘Operation Lotus’ commenced in Karnataka in 2008.

The BJP chief said it was the Congress which started the “aaya ram, gaya ram” culture, referring to the practice of MLAs defecting to other parties, he said.

“In 1967, the then prime minister Indira Gandhi had said that ‘gaya ram has now become aaya ram’ when an MLA of her United Front government had joined and quit the Congress three times in a gap of 15 days,” he said.

The former chief minister said it would be better if Siddaramaiah and Venugopal studied political history to know what happened in Haryana where the Congress had formed the government with Bhajan Lal with the help of 36 Janata Party MLAs.

The Congress is continuing this culture, Yeddyurappa said.

It looked like that Siddaramaiah had forgotten that he too joined the Congress with the same culture, he added.

Yeddyurappa said the BJP was not lusting for power.

With 104 seats, the BJP is functioning as a vigilant and constructive opposition party and the Congress and the JD(S) with 80 and 37 seats, respectively, had formed an unholy alliance to form the government, he said.

Kumaraswamy and Siddaramaiah should realise that this is first time in the history of legislature that a party with more than 100 seats is sitting in the opposition.

Yeddyurappa said the BJP’s MLAs assembled at a Gurugram hotel to discuss the strategy to win the upcoming Lok Sabha elections.

“If 104 MLAs of our party meet at one place and discuss the strategy to win the Lok Sabha, what is your problem? It is your responsibility to keep your party MLAs under control. If you scream the way you have been doing, it only shows your helplessness,” he said.

Taking a dig at Venugopal’s remarks that “glorious days” of the grand old party must return, Yeddyurappa asked if he was referring to the return of “multi-crore scams of the Congress-led UPA regime”.

He accused the Congress and the JD(S) of fooling people and said while the two parties were friends in Karnataka, they were enemies in Kolkata.

“As usual the JD(S) has been playing a double-game. The JD(S) needs the Congress on the one hand, and on the other, the JD(S) wants ‘mahagathbandhan’, which the Congress does not want,” Yeddyurappa claimed.

The double standards of these parties showed that there is no alternative to Prime Minister Narendra Modi, he said.
