Nanosatellite from SpaceX launches into space with Singapore tech start-up's thruster
https://str.sg/wQ3MSINGAPORE - A nanosatellite from billionaire Elon Musk's company, SpaceX, launched into orbit early on Friday (Jan 14) morning, bringing along with it a thruster that was designed and produced by a Singaporean tech start-up.The thruster engine was from Aliena, a company started in 2018 by two students who met while working on their PhDs at the Space Propulsion Centre in the National Technological University (NTU).
A thruster is used by satellites to make occasional firings to keep them in orbit, otherwise they would fall and re-enter Earth's atmosphere.The nanosatellite was launched into orbit at 12.28am Singapore time, from the SpaceX Falcon 9's Transporter-3 mission in Cape Canaveral Space Force Station, Florida.Read more: The Straits Times »

We won't ban it but we'll penalise you for using it to earn money Hot milf I am very happy n excited now
2 party system unlikely to happen in S'pore, but 'ownself check ownself' is a virtue: Ong Ye KungThe minister explained that Singapore was not a big polity like the UK or U.S. True: u need to a democracy to be a multi-party system. Finally someone who officially states Singapore isnt a democracy. I give that dude credit for that. Of course there'll won't be a two party political system if you continue to put up tyrannical and undemocratic barriers against the opposition. And so now you have progressed from ownself check ownself to ownself praise ownself. Your arrogance knows no bounds Good governance is more important than multiple party system. Multiple parties only incite social unrest and not good for economic development.

sg/wQ3M SINGAPORE - A nanosatellite from billionaire Elon Musk's company, SpaceX, launched into orbit early on Friday (Jan 14) morning, bringing along with it a thruster that was designed and produced by a Singaporean tech start-up. The thruster engine was from Aliena, a company started in 2018 by two students who met while working on their PhDs at the Space Propulsion Centre in the National Technological University (NTU). A thruster is used by satellites to make occasional firings to keep them in orbit, otherwise they would fall and re-enter Earth's atmosphere. Seven players have withdrawn from the ongoing tournament in New Delhi after testing positive for COVID-19, organisers said on Thursday. The nanosatellite was launched into orbit at 12.28am Singapore time, from the SpaceX Falcon 9's Transporter-3 mission in Cape Canaveral Space Force Station, Florida. This follows Oppo's Find N unveiled late last year.
Compared to current Hall thrusters that require around 1,000 watts to keep larger satellites in orbit and are unsuitable for smaller spacecraft, Aliena's engine can keep a nanosatellite operational with less than 10 watts of power, comparable to the energy needed for an ant to take a few steps, according to the start-up The thruster also costs a fraction compared to current larger ones in the market that can go up to US$2. The duo had been scheduled to play Singapore’s Terry Hee and Tan Wei Han on Thursday.2 million (S$2.9 million) per thruster, said Dr Mark Lim Jian Wei, 33, co-founder and chief executive of Aliena. He added that propulsion systems like the one Aliena develops are important to be able to actively manoeuvre satellites. His next opponent is Russia’s Sergey Sirant. China had earlier submitted a note to the United Nations Office for Outer Space Affairs in December last year that claimed two SpaceX satellites flew too close to the country's space station.com/watch?v=yzdwfCZ9XKY[/embed] Samsung is of course leading the charge on the foldable scene.
Dr Lim said:"Propulsion systems allow for collision avoidance to be executed in space. Without a propulsion system, if you know that there's a satellite going to approach you, the only thing you can do is to pray right?" Since forming Aliena in 2018 with co-founder and chief technology officer George-Cristian Potrivitu, 30, more than 20 people have worked on the thruster. Hee and Loh Kean Hean were scheduled to play against India’s Gaurav Deswal and Shubham Yadav in the men’s doubles later on Thursday. Aliena’s Hall effect thruster that allows small satellites to move in space with less than 10 watts, comparable to the amount of effort an ant uses to take a few steps forward. PHOTO: ALIENA Mr Potrivitu, who is also an NTU PhD candidate, said the pair was inspired to start the company to solve real world problems such as sustainability in space. He said:"We saw how satellites were becoming more prevalent - especially miniature satellites, and there was a demand for propulsion systems that could enable sustainability in space and on ground. Other rumours include the return of Touch ID, switching to USB-C charging, removing the charging port completely, and removing the SIM card slot.
"We can enable sustainability in space through giving satellites the ability to decommission themselves after their end of life, leaving behind a clean space for the generations to follow. And to also empower sustainability on Earth through the high resolution images that can be acquired to monitor and mitigate the effects of climate change" Aliena has since secured separate orders from an undisclosed customer and has received interest from other enterprises for the use of its engines in their satellites.
