They will use in-situ derived propellant such as hydrogen and oxygen from water," Mueller said. "These are the first steps to opening up the solar system transportation routes to humanity and resource mining robots." Join our Space Forums to keep talking space on the latest missions, night...
In July, agency officials announced that its next Mars rover, slated to blast off in 2020, will carry an instrument that will generate oxygen from the carbon-dioxide-rich Martian atmosphere. More missions coming? NASA isn't the only entity eyeing the moon's resources. A number of private ...
They rely on a recycling air system, which could be adapted for the Moon. This could look like planting oxygen-emitting plants in lunar greenhouses, and then sending the purified air through sealed habitation pods. Scientific challenge aside, this would be an entirely new way of life that we...
While the installation process was relatively straightforward, the port did not function properly on all devices. The developer mentions that “wallpapers cannot be displayed on the Always-On Display (AOD) on some OEM skins (One UI,OxygenOS).” However, during our testing, we encountered addition...

The main engines provide the remainder of the thrust (29 percent) to lift the shuttle off the pad and into orbit. The engines burn liquid hydrogen and liquid oxygen, which are stored in the external fuel tank (ET), at a ratio of 6:1. They draw liquid hydrogen and oxygen from the ET...
A sampling of aurora colors from some of the photos I’ve taken. The atmospheric gas determines the color at altitude (mainly atomic oxygen and nitrogen), its electrical state, and the energy of the particle that hits the gas. The colors of the aurora are made up of red, blue, and ...
Of course, no one would be able to complete that walk continuously — on Mars, Earth or anywhere. Even if the person were able to bring enough oxygen, water and food with them, and could eat and drink while walking, they would still need to stop to sleep. Assuming the astronaut slept...
