Juno's high-speed flybys around Jupiter, called perijoves, happen once every 53.5 days and have allowed NASA to document the gas giant like never before. The most recent trip (Juno's 14th perijove) occurred on July 16. Here's what the probe saw.
Satellites and space probes have a unique way of putting humanity in its place: by turning a lens on planet Earth and its pockmarked moon. We all live on a tiny rock that's hopelessly lost in the cosmic void.
Astronauts explain why nobody has visited the moon in more than 45 years — and the reasons are depressing
The last time anyone visited the moon was in December 1972, during NASA's Apollo 17 mission. Astronauts often say the biggest reasons why humans haven't returned to the moon are budgetary and political hurdles — not scientific or technical challenges.
Chris Hadfield, a former astronaut, says the rocket and spaceship technology could have been created decades ago to send people to and from Mars — but at extraordinary risk of death. He thinks we need some possibly "outlandish" solutions to make travel to the red planet safe and practical.
NASA’s Mars Opportunity rover is celebrating its 15th birthday with a nap because of a giant dust storm. Look back at its unlikely journey.
The Opportunity rover was launched to Mars 15 years ago. But the rover's future is far from certain, since it is weathering a massive dust storm and has gone completely dark. Here's a look at what we've learned from Opportunity.
Blue Origin, the space flight project founded by Jeff Bezos in 2000, already has plans for space tourism and has completed some test flights with reusable rockets. Now, the company aims to land on the moon within 5 years.
Buzz Aldrin, who walked on the moon, wants the lunar surface to become a launch pad for Mars — here’s how
Former NASA astronaut and moon-walker Buzz Aldrin told Business Insider about his vision for a shuttling system to Mars. He said there's no reason to build a permanent human colony on the moon, but Mars is a different story.
This seasoned NASA astronaut wore SpaceX and Boeing’s new spacesuits — here’s what she thinks of them
Boeing and SpaceX have designed and built new spacesuits to protect NASA's finest. Astronaut Sunita "Suni" Williams — who's worn multiple spacesuits, spent 7 months in orbit, and is a member of NASA's Commercial Crew Program — has tried on the companies' new suits. Here's what she thinks.
NASA just launched 20 mice into space on a SpaceX rocket while their identical twins stay on Earth — here’s what they hope to learn
NASA is sending two families of mice to the International Space Station while their siblings stay in gravity-influenced environments on Earth. Scientists hope to leran more about how space impacts the microbiome and what we might do to better combat stress.
NASA ‘tasted’ complex organic compounds in a blast of water from one of Saturn’s moons — and can’t yet rule out the poss...
Enceladus, an ice-encrusted moon of Saturn, hides an ocean of saltwater that blasts ice into space. NASA flew its Cassini spacecraft through the ice geysers in 2015, and scientists detected complex organic molecules. Though not proof of alien life, it's a good sign for the habitability of Enceladus.
