Sending humans virtually anywhere in space beyond the Moon pushes logistics of health, food, and psychology to limits we're only just beginning to grasp. A staple solution to these problems in science fiction is to simply put the void-travelers to bed for a while. In a sleep-like state akin to hibernation or torpor, metabolism drops, and the mind is spared the boredom of waiting out endless empty hours.

The ice giant could represent the galaxy’s most common type of planet, but we know very little about it. Now scientists have declared that seeing the world up-close is a top priority.

Are there rogue stars masquerading as planets in NASA’s Exoplanet Archive?

Hibernating astronauts could be the best way to save mission costs, reduce the size of spacecraft by a third and keep crew healthy on their way to Mars. An ESA-led investigation suggests that human hibernation goes beyond the realm of science-fiction and may become a game-changing technique for space travel.

Shares of Virgin Galactic fell in trading on Thursday after the company announced plans to raise up to $500 million in debt. “The company intends to use the net proceeds from the offering to fund working capital, general and administrative matters and capital expenditures to accelerate the development of its spacecraft fleet,” Virgin Galactic said in a statment.

There's been a lot of hubbub surrounding Don't Look Up, a recent Netflix movie about a planet-killing comet heading towards Earth, but 2022 is actually a great year to turn your eyes to the sky. There will be missions to Mars and the moon, a dance of planets and eclipses to enjoy. And better yet, no giant comet that threatens to destroy life as we know it on Earth.

A new analysis of the fabled Bussard Ramjet shows that the spacecraft would need an impossibly big magnetic field to achieve interstellar travel.

NASA's next-generation space observatory has sailed beyond the orbit of the moon after nailing the second of three required course-correction burns, agency officials said Monday. The long-awaited James Webb Space Telescope launched on Saturday (Dec. 25), beginning a one-month deployment process. Over the course of that deployment, the observatory must execute three burns to adjust its trajectory, the first of which began 12.5 hours after launch and lasted 65 minutes; the second, much shorter burn, is now also complete.

An audio track collected during Jupiter mission’s Ganymede flyby offers a dramatic ride-along. It is one highlights mission scientists shared in a briefing at American Geophysical Union Fall Meeting. Sounds from a Ganymede flyby, magnetic fields, and remarkable comparisons between Jupiter and Earth’s oceans and atmospheres were discussed during a briefing today on NASA’s Juno mission to Jupiter at the American Geophysical Union Fall Meeting in New Orleans.

The icy process may be present on other worlds.

A Nasa spacecraft has officially “touched” the sun, plunging through the unexplored solar atmosphere known as the corona. Scientists announced the news Tuesday during a meeting of the American Geophysical Union.

1971 was a crummy year for the Soviet Mars program. Of the four robotic spacecraft the USSR sent toward the Red Planet that year, one never made it out of Earth orbit, two were stymied by Martian dust storms, and another crashed into Mars like a speeding bullet. But the Mars 3 lander had better luck. Somewhat.

NASA's mission DART will test our ability to redirect an asteroid by quite literally crashing into it — but the spacecraft will also test a new type of propulsion system for the agency.

Want to be one of the first to take a ride on Virgin Galactic's spaceship? That'll cost you a cool $450,000.

A NASA spacecraft is giving the best-ever 3D model of the largest planet of our solar system. The Juno mission is using its second extended phase to peer far into the clouds of Jupiter, using a polar-orbiting view that no previous spacecraft was able to access.

Scientists may have detected signs of a planet transiting a star outside of the Milky Way, in what could be the first planet ever to be discovered outside our galaxy.

Attention asteroid aficionados: NASA is set to launch a series of spacecraft to visit and even bash some of the solar system's most enticing space rocks. The robotic trailblazer named Lucy is up first, blasting off this weekend on a 12-year cruise to swarms of asteroids out near Jupiter—unexplored time capsules from the dawn of the solar system. And yes, there will be diamonds in the sky with Lucy, on one of its science instruments, as well as lyrics from other Beatles' songs.

When the Soviet Union launched Sputnik 1 in 1957, it represented humanity's first significant foray into the cosmos. Our imagination was opened to the wonder and lure of space for human endeavor as science fiction suddenly became science fact.

The gargantuan Bernardinelli-Bernstein comet will strafe Saturn's orbit in 2031. Scientists are stoked.

NASA has announced that it will launch Psyche in August 2022 to reach the asteroid belt between Mars and Jupiter. But there is something unique about this spacecraft—it will travel across space using a "solar electric propulsion" system.
