For scientists, data from the Juno probe is yielding surprises — and more questions.
Scientists at NASA and universities across the US are developing promising new technologies for space exploration. But it's all happening way too slowly, one scientist says. The reason: Congress.
NASA says the first launch of the Orion spacecraft on Friday is “the dawn of the new era of space exploration" that will finally kick off the attempt to put humans on Mars.
You've always paid for space missions with your tax dollars, but now you can get even more involved thanks to a British team that's using Kickstarter to fund a new lunar probe. Donors will even get a chance to leave their hair on the Moon if they fork over enough cash.
It's hard to fathom our place in the solar system, until you look at a picture of Earth taken from near Saturn. NASA just released this composite photo, snapped by the Cassini space probe in July. Earth, Venus and Mars are all visible, but just pinpricks of light.
NASA has taken data from recent explorations of Mars and turned it into a cool animation showing how Mars might have evolved over the last 4 billion years. The simulation starts by flying over a beautiful, Earth-like planet with huge lakes as the planet slowly becomes today's barren, red landscape.
