Stuck successful abstraction for much than sixty days: How to tackle the Sunita Williams conundrum?
Sunita Williams and Barry Wilmore NASA astronauts and overmuch travelled abstraction explorers, person been stuck connected committee the International Space Station for much than 2 months now. A seasoned with galore grounds breaking flights and abstraction walks to her credit, Sunita Williams piloted a Boeing Starliner trial formation to the ISS connected June 5, 2024 and was expected to alert backmost aft 8 days. However, owed to respective logistical, operational and bundle issues, the spacecraft Calypso is presently immobile. While efforts are connected to marque it formation worthy, the evident difficulties with handling mechanical works successful abstraction arsenic good arsenic the constricted availability of skilled manpower successful the contiguous vicinity person thrown a spanner successful the plans.

Sunita Williams and Barry Wilmore
The ngo was a trial to measure the show of the caller spacecraft earlier it is utilized regularly. The Starliner was scheduled to statesman its instrumentality travel connected June 26.
Boeing Starliner Calypso
...several issues were detected successful immoderate of the cardinal mechanisms of the spacecraft adjacent earlier it docked astatine the ISS. There were leaks successful the propulsion strategy and immoderate of its thrusters started shutting down. However, contempt the glitches the Starliner reached the ISS safely.

That is not the lone issue. Five of the 28 manoeuvring thrusters person gone dormant and a propellant valve failed to adjacent completely, according to a study successful Reuters.
The unit successful abstraction and ngo managers successful Houston person been pursuing the fixes. Boeing claims to person fixed astir of the issues done a bid of simulations ? astir 1,00,000 ? with 27 thrusters present reportedly moving astatine afloat capacity. However, NASA has requested much information from Boeing, arsenic determination is uncertainty that the Starliner mightiness beryllium unsafe to alert backmost to Earth
The spacecraft that has been successful formation mode since 2019 has had a chequered past with problems perpetually hindering its progress. Boeing's rivalry with SpaceX and America's acold narration with Russia and China person besides been deterrents to the harmless instrumentality of the 2 astronauts.

What's the solution then?

The ngo undertaken by Elon Musk?s SpaceX is scheduled to motorboat successful September and instrumentality to Earth adjacent year. At archetypal 4 unit members were to beryllium aboard. But present 2 seats could beryllium kept bare to bring backmost Williams and Wilmore.
It is not the lone mode out. Multiple plans beryllium to get the astronauts backmost to Earth, including having them adjacent hitch a thrust connected a Russian Soyuz craft, reports USA TODAY.
Recently, NASA utilized a SpaceX rocket to present much nutrient and supplies, including other clothes.
Living successful space, wrong the ISS isn't easy. Although 4 different astronauts are presently successful agelong word residence there, the summation of Sunita Williams and Barry Wilmore has posed caller challenges.

Williams is suffering from bony density nonaccomplishment owed to prolonged vulnerability to microgravity. This tin pb to different wellness complications specified arsenic ocular impairment and the hazard of DNA damage, according to a study successful The Indian Express.
A travel that was expected to past a week stretching to infinity could pb to terrible accent and intelligence issues for the persons involved, onboard the ISS arsenic good arsenic connected earth.
My knowing of the concern is that determination are aggregate options to bring the 2 astronauts backmost to earth. As tin beryllium seen successful the picture, Cygnus 20, Soyuz MS-25, Progress 87 & 88 and SpaceX Crew-8 are inactive docked to the ISS.
But the viability of requisitioning them for the rescue appears to beryllium a Herculean task; for now.
Disclaimer: Albeit reflective of my attempts astatine appropriating Sunita Williams' Indian transportation and hence intelligibly biased, delight remainder assured that successful spite of the title, I person arsenic overmuch respect and interest for her co-traveller Barry 'Butch' Wilmore arsenic I person for her.
