Washington, May 8: Two NASA astronauts are set to go out for a spacewalk on May 16 to swap out thermal control gear that circulates ammonia to keep the International Space Station systems cool.

The excursion will be conducted by veteran spacewalkers Ricky Arnold and Drew Feustel, NASA said in a blog post on Monday.

The two astronauts will conduct a second spacewalk on June 14, it added. 

Space Station officials will preview the upcoming spacewalks live on NASA TV on Tuesday. 

On May 20, just four days after the first spacewalk, Orbital ATK is planning to launch its resupply flight on a four day trip to the orbital laboratory. 

For the cargo mission, Orbital ATK will launch its Cygnus spacecraft on an Antares rocket from the Wallops Flight Facility in Virginia, NASA said. 

Cygnus will resupply the Expedition 55 crew with new science experiments, crew supplies, station hardware and gear that will be installed on the June 14 spacewalk.

NASA also announced on Monday that it will host a media teleconference on May 10, to discuss select science investigations and technology demonstrations launching on the next Orbital ATK commercial resupply flight to space station.

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.
