The Dragon launch was expected to bring two tons of supplies to the ISS as part of a resupply mission.

The planned launch of the uncrewed Dragon to the International Space Station has been delayed due to a potential propellant leak.

As a team loaded the Dragon cargo spacecraft with propellant, it detected elevated vapor readings of mono-methyl hydrazine. NASA says the incident happened this past weekend, but it is not certain when the readings were detected.

According to the space agency, the fuel and oxidizer were unloaded from the offending portion of the spaceship in order to conduct a more thorough analysis. The planned launch of the Dragon to the International Space Station has been canceled. Wait a second, womp womp.

A new target launch date will be announced once the exact source of the elevated readings is determined.

SpaceNews reported that the Dragon uses MMH fuel and nitrogen tetroxide as oxidizers. The dragons are able to maneuver the spaceship.

Two tons of supplies will be brought to the International Space Station by the CRS 25 mission. The Dragon spaceship will eventually deliver.

new science investigations, supplies, and equipment for the international crew, including a study of immune aging and potential for reversing those effects. One of the primary payloads aboard the cargo flight is the Earth Surface Mineral Dust Source Investigation or EMIT. This tool will identify the composition of mineral dust from Earth’s arid regions and analyze dust carried through the atmosphere from deserts to see what effects it has on the planet, further advancing NASA’s data contributions to monitoring climate change. It also will carry an investigation from a team of students at Stanford University that will test the process of creating biopolymer soil composite, a concrete alternative, in microgravity.

The current crew on the International Space Station will have to wait for some things.

The design of the next generation of Starlink satellites was revealed last month by the company. Musk's plans for the company are not without their flaws. It is almost certain that Musk's plan to send a million people to Mars won't happen by the given time frame.

Musk's megarocket will deploy Starlink satellites.
