NASA astronauts Sunita Williams and Butch Wilmore are set to come back to Earth in SpaceX’s Crew Dragon spacecraft, but there are complications surrounding their return. The crew only has one SpaceX suit that fits the astronauts, while the Boeing suits they originally wore are not compatible with the spacecraft. This has raised concerns about their safety and the support they will have during their long-duration mission.
NASA astronauts Sunita Williams and Butch Wilmore are scheduled to return to Earth in SpaceX's Crew Dragon spacecraft, but a critical issue has arisen: there is only one SpaceX suit that fits the astronauts. The Boeing suits they originally wore are not compatible with the Crew Dragon, creating concerns about their safety and the support they will have during their long-duration mission.
Background:
In 2014, NASA awarded Boeing and SpaceX contracts to develop new commercial crew transportation systems for the International Space Station. Both companies designed their own spacecraft and suits, with the expectation that they would be interchangeable.
However, it was later discovered that the Boeing suits were incompatible with the SpaceX Crew Dragon capsule. This is because the suits use different pressure control systems and are designed for slightly different cabin pressures.
Current Situation:
NASA is currently working with Boeing and SpaceX to find a solution to the suit shortage. One option is to modify the Boeing suits to make them compatible with the Crew Dragon. Another option is to purchase additional SpaceX suits. However, both of these solutions would take time and money.
In the meantime, the astronauts are using the single SpaceX suit to conduct spacewalks outside the space station. This suit is not ideal, as it is slightly too large for both Williams and Wilmore.
Concerns:
The suit shortage has raised concerns about the safety of the astronauts. If there is an emergency during re-entry, the astronauts may not have access to a properly fitting suit. Additionally, the lack of a backup suit could limit the astronauts' ability to conduct spacewalks and perform other tasks outside the space station.
Top 5 FAQs:
1. Why don't the Boeing suits fit the Crew Dragon?
The suits use different pressure control systems and are designed for slightly different cabin pressures.
2. What is NASA doing to resolve the issue?
NASA is working with Boeing and SpaceX to find a solution, including modifying the Boeing suits or purchasing additional SpaceX suits.
3. How does the suit shortage affect the astronauts' safety?
In an emergency, the astronauts may not have access to a properly fitting suit. Additionally, the lack of a backup suit could limit their ability to conduct spacewalks and other tasks outside the space station.
4. What is the timeline for resolving the issue?
The timeline for resolving the issue is unclear. It could take weeks or months to modify the Boeing suits or purchase additional SpaceX suits.
5. What is the future of the SpaceX Crew Dragon?
The Crew Dragon is scheduled to make its first operational flight with four astronauts in May 2023. However, the suit shortage could delay this flight or limit the number of astronauts on board.
In a surprising turn of events, Kenyan President William Ruto has cancelled two major deals with India's Adani Group after its founder was indicted in the US for corruption.

Ruto cited "new information" from investigative agencies and partner nations as the reason for the cancellation, drawing thunderous applause from lawmakers in his state of the nation address. The move has sparked concerns about transparency and value for money in these deals, which have faced criticism from politicians and the public.

In a move to slow Russian advances in Ukraine, US President Joe Biden has approved the provision of anti-personnel mines to the Ukrainian military. This comes as reports state that North Korean troops have joined Russian marines and airborne units in battles throughout the country. The addition of anti-personnel mines marks a new level of assistance from the US in the ongoing conflict, with the mines being more deadly and longer-lasting than the previously provided anti-tank mines. Meanwhile, Ukraine's air defence units are actively working to repel a Russian air attack on the capital city of Kyiv.
