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.

KSRTC introduces gender ticketing in buses across Kerala
Thiruvananthapuram (PTI): The KSRCTC on Saturday began implementing gender ticketing in buses operating across the state.
According to a Kerala State Road Transport Corporation (KSRTC) circular issued on Friday, the gender ticketing system is intended to record whether a passenger is a woman, a man or a child in tickets issued on KSRTC buses from Saturday.
To facilitate the system, Electronic Ticketing Machines (ETMs) have been updated.
The circular stated that conductors in all KSRTC depots should record the gender category of passengers while issuing tickets through the ETMs.
Options for women, men, and children have been included in the ETMs to identify passenger categories when issuing tickets.
The printed tickets generated by the ETMs will also indicate the passenger's category, officials said.
The UDF had promised free KSRTC travel for women across the state during the Assembly election campaign.
UDF, which won 102 of 140 seats, would soon form the government after the Congress party finalises the discussion on the next Chief Minister.
The introduction of gender ticketing is being viewed as an effort to estimate the number of women travelling daily on KSRTC buses before implementing the poll promise.
Some conductors have reportedly raised concerns over the additional time required to record passenger details, especially during rush hours.
