SpaceX Scrubs First Orbital Flight Test Of Starship Due To Technical Tissues, No Launch Till Next 48 Hours
A pressurant valve of the Starship system appears to be frozen, SpaceX CEO Elon Musk said on Twitter. As a result, the first launch attempt has been scrubbed.
SpaceX cancelled the first orbital flight test of Starship on Monday, Apr 17, 2023, due to technical issues. Starship, the most powerful launch vehicle ever built, was scheduled to launch from Starbase in Texas at 6:50 pm IST on Monday.
However, a pressurant valve appears to be frozen, SpaceX CEO Elon Musk said on Twitter. As a result, the first launch attempt has been scrubbed. Since the process of recycling the fuels takes about 48 hours, there is no possibility of a launch on April 18 or 19.
A pressurant valve appears to be frozen, so unless it starts operating soon, no launch today

A fully integrated Starship spacecraft and Super Heavy rocket – together called Starship – was stacked at Starbase, one of the world's first commercial spaceports designed for orbital missions, and the site for development and manufacturing of Starship.
The SpaceX team is still working towards the next available launch opportunity for Starship.

According to SpaceX, the Starship system will be able to carry up to 100 people on long-duration, interplanetary flights. The Starship system will also enable satellite delivery and the development of a Moon base.
All about the Starship system
The Starship system represents a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond, and will be the world's most powerful launch vehicle ever developed, SpaceX says on its website.
The Starship system has a height of 120 metres, a diameter of 9 metres, and a payload capacity of 100 to 150 metric tonnes. It is capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes expendable, which means that while it can carry an extra weight of 250 tonnes, that portion can be used only once, and will subsequently be destroyed.
The fully reusable spacecraft and second stage of the Starship system is called Starship, which has an integrated payload section and is capable of carrying crew and cargo to Earth orbit, the Moon, Mars and beyond.
Starship can also carry out point-to-point transport on Earth, and enable travel to any region in the world in one hour or less.
Starship has a height of 50 metres, a diameter of nine metres, and a propellant capacity of 1,200 tonnes.
The first stage, or booster of the Starship launch system is called Super Heavy. It is fully reusable, will be powered by 33 Raptor engines using sub-cooled liquid methane and liquid oxygen, and will re-enter Earth's atmosphere to land back at the launch site. Sub-cooled propellants are those which have been cooled to a temperature below their boiling point.
Super Heavy has a height of 69 metres, a diameter of nine metres, and a propellant capacity of 3,400 tonnes.
The Raptor engines which will power the Starship system are reusable methane-oxygen staged-combustion engines. The Raptor Engine has twice the thrust of the Falcon 9 Merlin engine. A total of six engines, which include three Raptor engines, and three Raptor Vacuum (RVac) engines, will power the Starship spacecraft.
RVac engines are designed for use in the vacuum of space.
As many as 33 Raptor engines, with 13 in the centre of Super Heavy, and the remaining 20 around the perimeter of its aft end will power the booster.
Each Raptor engine has a diameter of 1.3 metres, and a height of 3.1 metres.
