Why NASA Picked Elon Musk's SpaceX To Bring Back Astronauts From Space

NASA today picked Elon Musk's SpaceX to bring back Sunita Williams and Barry Wilmore from space next year. Eighty days ago, the two astronauts arrived at the International Space Station aboard Boeing's Starliner for an 8-day mission. They were forced to extend their stay because of major technical issues with the Boeing capsule.

The astronauts are expected to return in February next year, after spending a total of eight months in orbit, on a SpaceX Crew Dragon spacecraft due to launch next month as part of a routine astronaut rotation mission.

NASA chief Bill Nelson said Starliner's propulsion system is too risky to carry its first crew home. Starliner will undock from the ISS without a crew and attempt to return to Earth as it would have with astronauts aboard.

The space agency's decision to pick Boeing's top space rival marked a fresh setback to the Starliner test mission. Boeing had hoped the mission would redeem the troubled program after years of development problems and over $1.6 billion in budget overruns since 2016.

Nelson said he discussed the agency's decision with Boeing's new CEO Kelly Ortberg.

The SpaceX Crew-9 mission will take off in late September, but carrying only two passengers instead of the originally planned four.

It will remain moored to the ISS until its scheduled return in February, bringing back its own crew members plus their two stranded colleagues.

The veteran NASA astronauts, both former military test pilots, became the first crew to ride Starliner on June 5 when they were launched to the ISS.

Starliner's propulsion system suffered multiple glitches beginning in the first 24 hours of its flight to the ISS, triggering months of cascading delays. Five of its 28 thrusters failed and it sprang several leaks of helium, which is used to pressurise the thrusters.

Since Starliner docked to the ISS in June, Boeing has scrambled to investigate what caused its thruster mishaps and helium leaks. The company arranged tests and simulations on Earth to gather data that it has used to try and convince NASA officials that Starliner is safe to fly the crew back home.

But results from that testing raised more difficult engineering questions and ultimately failed to quell NASA officials' concerns about Starliner's ability to make its crewed return trip - the most daunting and complex part of the test mission.

PM Modi To Reschedule 3-Nation Europe Visit As Tensions With Pakistan Soar

Prime Minister Narendra Modi has put his three-nation Europe visit on hold as tensions between India and Pakistan have surged in the wake of the terror attack in Jammu and Kashmir's Pahalgam in which 26 civilians were killed by Pak-linked terrorists in a religiously-motivated terror attack. India responded on Wednesday with precision missile strikes on terror camps in Pakistan and Pakistan-occupied Kashmir. PM Modi, who is closely-monitoring the situation, has reportedly asked for his visit to Croatia, Norway, and the Netherlands, which was due next week, to be rescheduled. As per his original schedule Prime Minister Modi was to commence his official visit to the three nations on May 13. He was also going to participate in the India-Nordic Summit in Oslo on May 15 and 16. All three countries have been informed about the change in PM Modi's schedule. They have also been appraised about the current situation between India and Pakistan. Last month too, on the day of the Pahalga...

Delhi to Get More EV Charging, Battery Swapping Stations as Cab Aggregators Increase E-Bikes

The NDMC is planning to increase the number of EV charging stations in Lutyens' Delhi and even provide battery swapping facilities at some of these points, a senior official said on Wednesday. With Delhi being among the most polluted capitals in the world, the New Delhi Municipal Council (NDMC) has been making a push for electric vehicles to nudge residents to opt for cleaner vehicle options. There are around 100 electric vehicle (EV) charging stations across the national capital at present and this would be the first time that some of them would have battery swapping facilities, which is quite prominent in Western countries, he said. The official said the aim is to provide easy accessibility to charging stations and to save time by providing swapping facilities. This will give a major push to EVs in the city. Various PSUs, including the Rajasthan Electronics and Instruments Limited (REIL) and the Kerala State Electronics Development Corporation Limited (KELTRON), have approac...

After Nitish Kumar's 'Praise', BJP Says Doors Closed For Him

The opposition BJP in Bihar on Thursday said that its doors were "closed" for Chief Minister Nitish Kumar who dumped the saffron party a year ago, stripping it of power in the state. State BJP President Samrat Choudhary made the averment to this effect in reply to queries from journalists about the Janata Dal United leader's address to the convocation ceremony of Mahatma Gandhi Central University at Motihari. Speaking in the presence of President Droupadi Murmu and Governor Rajendra Arlekar, Mr Kumar had freely spoken of the tussle he had with the then Congress government at the Centre for getting a university approved for Motihari, where Mahatma Gandhi had launched the Champaran Satyagraha. Without mentioning Prime Minister Narendra Modi by name, Mr Kumar acknowledged that the project saw the light of the day only after a change of guard "in 2014" as the UPA government "initially refused and after much persuasion agreed in principle but did not move for...
