The three-way comparison operator or "spaceship operator" for numbers is denoted as <=> in Perl, Ruby, Apache Groovy, PHP, Eclipse Ceylon, and C++, and is called the spaceship operator. [2] In C++, the C++20 revision adds the spaceship operator <=>, which returns a value that encodes whether the 2 values are equal, less, greater, or unordered ...
Starship flight test 5 was the fifth flight test of a SpaceX Starship launch vehicle. SpaceX performed the flight test on October 13, 2024. The prototype vehicles flown were the Starship Ship 30 upper-stage and Super Heavy Booster 12 .
A leak in the aft section developed during a planned liquid oxygen venting, resulting in a combustion event that interrupted communication between the craft’s flight computers, causing full engine shutdown, [20] after which the flight termination system successfully destroyed the ship as it reached an altitude of ~148 km and velocity of ...
Starship flight test 1 was the maiden flight of the integrated SpaceX Starship launch vehicle. SpaceX performed the flight test on April 20, 2023. [5] The prototype vehicle was destroyed less than four minutes after lifting off from the SpaceX Starbase in Boca Chica, Texas. [6]
The Block 1 version of the ship (used through November 2024) produces a total of 12.25 MN (2,750,000 lb f) [1] almost triple the thrust of the Saturn V second stage, with this total being expected to increase to 15.69 MN (3,530,000 lb f) for Block 2 boosters and later up to 26.48 MN (5,950,000 lb f) with the Block 3 vehicle.

The selection and training of astronauts are integrated processes to ensure the crew members are qualified for space missions. [6] The training is categorized into five objectives to train the astronauts on the general and specific aspects: basic training, advanced training, mission-specific training, onboard training, and proficiency maintenance training.

The upper stage Starship spacecraft reached an initial apogee of 190 km (120 mi) and a perigee of 8 km (5.0 mi) at a 26.3 degree orbit, marking the first time Starship has had positive perigee. At 22:37:46, the Ship successfully conducted the first Raptor engine relight in the vacuum of space, which raised the apogee to 228 km (142 mi) and the ...
A "Hello, World!"program is usually a simple computer program that emits (or displays) to the screen (often the console) a message similar to "Hello, World!".A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.
