The US space agency has thrown open a challenge to win over Rs 26 lakh, calling the global community to send novel design concepts for compact toilets that can operate in both microgravity and lunar gravity.

NASA is preparing for return to the Moon and innumerable activities to equip, shelter, and otherwise support future astronauts are underway.

The astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity.

NASA said that while astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth.

The public designs for space toilet may be adapted for use in the Artemis lunar landers that take humans back to the Moon.

"Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only," the US space agency said in a statement.

NASA's Human Landing System Programme is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity.

The new NASA challenge includes a Technical category and Junior category and the last date to send designs is August 17.

NASA's Artemis Moon mission will land the first woman and next man on the lunar surface by 2024.

The Artemis programme is part of America's broader Moon to Mars exploration approach, in which astronauts will explore the Moon and experience gained there to enable humanity's next giant leap, sending humans to Mars.

New Delhi, Mar 14: Excise duty on petrol and diesel was on Saturday hiked by ₹3 per litre as the government looked to mop up gains arising from fall in international oil prices.

Special excise duty on petrol was hiked by ₹2 to ₹8 per litre incase of petrol and to Rs 4 incase of diesel, an official notification said.

Additionally, road cess on petrol was raised by ₹1 per litre each on petrol and diesel to ₹10.

The increase in excise duty would in normal course result in a hike in petrol and diesel prices but most of it would be adjusted against the fall in rates that would have necessitated because of slump in international oil prices.

In a first, the Supreme Court on Friday allowed the service of summons and notices, a necessity in almost all legal proceedings, through instant messenger like WhatsApp as well as by e-mail and fax.

A bench headed by Chief Justice SA Bobde observed that it has been brought to the notice of the court that it is not feasible to visit post offices for service of notices, summons, and pleadings. The bench also comprising Justices AS Bopanna and R Subhash Reddy observed that notice and summons should be sent through e-mail on the same day along with instant message through WhatsApp and other phone messenger services.

The bench clarified that all methods should be deployed for a valid service on the party. "Two blue ticks would convey that the receiver has seen the notice," noted the bench.

The bench declined the request of the Attorney General for specifically naming WhatsApp as a mode of effectuating service. The top court noted that it would not be practical to specify only WhatsApp. The apex court also permitted RBI to extend the validity of cheques in the backdrop of lockdown to contain the coronavirus outbreak.

Senior advocate V Giri representing RBI informed the bench that he had circulated the note regarding validity of a cheque as directions issued on the previous hearing.

The bench noted that it will be in discretion of the RBI to issue orders which are suitable to alter the validity of the period of a cheque.

During an earlier hearing on the matter on July 7, the Attorney General contended before the top court that the Centre had some reservations in connection with the utilization of mobile applications like WhatsApp and other apps for service of summons. The Centre's top law officer informed the apex court that these apps claimed to be encrypted, and they were not trustworthy.

The RBI counsel had contended before the top court that it was considering clarifying the validity of a cheque which has been reduced to 3 months from 6 months.
