SpaceX's powerful rocket tech could put lives at risk: NASA advisors
Washington, May 7: An approach used by SpaceX to make its Falcon 9 rocket more powerful could put the lives of astronauts at risk, NASA's safety experts have warned.
To make the Falcon 9 rocket even more powerful, SpaceX came up with the idea of keeping the propellant at super-cold temperatures to shrink its size, allowing them to pack more of it into the tanks. But the approach comes with a major risk, The Washington Post reported on Saturday citing the experts.
The new approach requires the propellant to be loaded just before takeoff, while astronauts are aboard, but an accident during this manoeuvre, known as "load-and-go," could set off an explosion.
As NASA and SpaceX prepare to launch humans into orbit as early as this year, one watchdog group labelled load-and-go a "potential safety risk," the Post reported.
In a letter, a NASA advisory group warned that the method was "contrary to booster safety criteria that has been in place for over 50 years."
SpaceX suffered a setback in September 2016 when a Falcon 9 rocket blew up while it was being fuelled ahead of an engine test.
As a result of the explosion, a multi-million dollar satellite was lost. Although no one was hurt in the incident, it raised safety concerns in the minds of the people at NASA.
The report quoted NASA's William Gerstenmaier as saying that the agency had not decided whether it would allow SpaceX to load crews before loading the fuel.

Siddaramaiah defends BPL ration card cancellation, says only ineligible beneficiaries affected
New Delhi, Nov 21: In a strong defence of the Karnataka government's move to cancel ration cards, Chief Minister Siddaramaiah on Thursday clarified that only government employees and income tax payers are being weeded out from the Below Poverty Line (BPL) list, not eligible poor beneficiaries.
Talking to reporters, Siddaramaiah asserted that the cancellation is in line with the National Food Security Act, which explicitly bars government employees and income tax payers from receiving BPL ration cards.
He accused the Bharatiya Janata Party (BJP) of raising a politically motivated issue despite originally opposing the food security legislation.
"The rights of eligible ration card holders will be fully protected," the chief minister emphasised, dismissing opposition claims that the move was linked to fund constraints for implementing poll promises.

The controversy stems from the Karnataka government's recent survey identifying 22.63 lakh BPL card-holders as ineligible. This move has triggered a political slugfest between the ruling Congress and the BJP.
Union Food Minister Pralhad Joshi claimed the central government had directed the state to clean the beneficiary lists. He alleged that the card cancellation was a strategy to avoid implementing the state's Gruha Lakshmi Yojana scheme.
Siddaramaiah hit back, reminding that the food security law was introduced during the Manmohan Singh government in 2013 to protect poor citizens' interests. He criticised the BJP for previously reducing food grain allocation from seven kg to five kg per beneficiary during B S Yediyurappa's tenure.
The chief minister categorically stated that there would be no compromise on the five poll guarantees and that sufficient funds were available for their implementation.
Siddaramaiah was in the national capital for the launch of Karnataka Cooperative Milk Producers' Federation Ltd's Nandini brands in Delhi. He also met Union Finance Minister Nirmala Sitharaman on the issue of farm loan.
