NASA is using a mixed reality space station to train astronauts

  NASA is using a mixed reality space station to train astronauts According to a video that Unreal Engine and NASA released earlier this month, their mixed reality system shows various elements of, and instruments on board the ISS, including different exercise machines and tools that astronauts use for maintenance work there. The simulator is different than the previously-released educational experience, Mission: ISS for Oculus.Among other things, the mixed reality ISS app sweeps astronauts-in-training off their feet with an “active response gravity offload system.” It works in conjunction with a robotic crane that makes the trainee feel like he or she would in micro-, lunar- or Martian gravity.

In 2009, NASA’s Ice, Cloud, and Land Elevation Satellite (ICESat) stopped taking pictures after six years in orbit. ICESat-2 wasn't going to pick up the slack until 2015—and the project has since been delayed until 2018. That's a long time in the life of Earth’s rapidly changing polar regions, where ice is changing in thickness and span with troubling speed.

That's why NASA launched the oh-so-cooly named Operation Icebridge, a series of flights over the Arctic and Antarctic regions designed to take high resolution photos (along with additional readings) to record what’s happening in the poles in the meantime.

Hubble Has Captured A Stunning Close-Up Portrait Of Jupiter

  Hubble Has Captured A Stunning Close-Up Portrait Of Jupiter Astronomers have seized the opportunity to capture a stunning portrait of Jupiter as it made its closest approach to Earth in a year. NASA's Juno spacecraft has spent five long years traveling to Jupiter and has been beaming back incredible, never-before-seen images of the giant planet. We take a look at some of the newest images from the mysterious planet.

Operation Icebridge just completed its 2017 run over the Arctic (the Antarctic mission will happen later this year). Although the analysis of the data is still a few weeks out, the images they’ve taken are stunning—and worthy of your attention. Here are some of the best for your enjoyment.
