James Webb Space Telescope sails beyond the orbit of the moon after 2nd course correction
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.

50 years ago, Russia landed on Mars for 15 seconds — and taught America a lesson
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.

Lucy in the sky: Spacecraft will visit record 8 asteroids
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.

Want to go to Mars? Better leave when the Sun is active to minimize galactic radiation poisoning
If the idea of sending humans to Mars is a romantic one, the reality of it is a bucket of cold water. Going to Mars is hard. Something like half of all missions have failed for one reason or another, but adding humans into the mix makes things far harder.

DoD looking for commercially available nuclear propulsion for small spacecraft
The Defense Innovation Unit last week issued a call for bids for small nuclear-powered engines for space missions beyond Earth orbit. DoD wants “lightweight, portable and long-duration power sources that can support propulsion and on-station power for sensing and communication on small- and medium-sized spacecraft,” says the solicitation.
