NASA deploys CubeSat to study Sun's soft x-rays

has deployed a bread loaf-sized (MinXSS) CubeSat from an airlock on the Space Station (ISS) to study the Sun's soft x-rays that can affect our communications systems.

Soft X-rays can disrupt the Earth's upper atmosphere and can hamper radio and Global Positioning System (GPS) signals travelling through the region.

The intensity of the soft x-ray emissions is continuously changing over a large range – with peak emission levels occurring during large eruptions on the Sun called

MinXSS will operate for up to 12 months and the data will also help scientists in understanding the physics behind

The soft X-rays carry information about the temperature, density and chemical composition of material in the Sun's atmosphere, allowing scientists to trace how events like flares and other processes heat the surrounding material in the Sun's atmosphere.

are a new, low-cost tool for space science missions.

Instead of the traditional space science missions, are designed to take narrowly targeted scientific observations, with only a few instruments.

For example, MinXSS uses a commercially purchased X-ray spectrometer for a detector and an extendable tape measure as a radio antenna.

MinXSS was launched via NASA's CubeSat Launch Initiative programme on 6 December last year aboard Orbital ATK's through NASA's Commercial Resupply Services contract.
