2032 asteroid impact chances just went up, but don't worry
(Robert Lea (created with Canva))
The odds of the asteroid 2024 YR4 impacting Earth in 2032 have increased to 1 in 43. Despite this, you still shouldn't worry about the potential impact of this asteroid. That's because experts expected the impact probability of this asteroid, which sits at the top of the Center for Near Earth Object Studies Sentry asteroid risk list, to increase. They also expect the chance of an impact to fall dramatically in the near future when we know more about its orbit.

NASA and General Atomics test future nuclear fuels
(General Atomics)
The first humans to Mars might someday ride a rocket propelled by a nuclear reactor to their destination. But before that can happen, nuclear thermal propulsion technologies still have quite a way to go before we could blast astronauts through space on a nuclear rocket. Earlier this month, though, General Atomics Electromagnetic Systems tested a new NTP reactor fuel at NASA's Marshall Space Flight Center in Alabama, to find out if the fuel could function in the extreme conditions of space.

Live-action 'Gundam' movie enters full production
(Bandai Namco / Legendary)
Thundering confidently into production this past week, Bandai Namco and Legendary's big-budget live-action "Gundam" movie is already assembling with recent news of the start of filming. This "Mobile Suit Gundam" project based on the insanely popular toy and anime line was originally revealed back in 2018, with Brian K. Vaughn reportedly set to write the script. It's been mostly radio silence ever since and fans were beginning to seriously doubt whether it would ever suit up for the silver screen.

Feb. 10, 1958: Radar bounced off Venus by MIT
(JAXA/NASA/Hinode))
On Feb. 10, 1958, scientists at MIT's Lincoln Laboratory bounced radar waves off of Venus. At the time, Venus was at a point in its orbit called inferior conjunction, where it is directly in between the Earth and the sun. Scientists beamed a radar signal toward Venus, which was about 28 million miles away at the time. It took about 5 minutes for the signal to bounce off of Venus and return to Earth. This was slightly shorter than they anticipated, which means that Venus was actually closer to Earth than scientists believed at the time.

Private FLIP moon rover replaces NASA's cancelled VIPER
(Astrobotic/Astrolab)
The VIPER news keeps coming. Pittsburgh-based company Astrobotic has found a replacement rover to fly on the first-ever mission of its Griffin moon lander. Griffin was originally supposed to deliver NASA's ice-hunting VIPER rover to the moon's south polar region on its debut flight, which is scheduled to launch late this year. The agency canceled the VIPER program last summer, leaving a big space open on Griffin. That space has finally been filled - by FLIP, a rover built by the California company Astrolab.

The moon will be unusually high in the sky tonight
(Chris Vaughan/Starry Night)
Even to a casual viewer, the waxing gibbous moon of Friday will appear unusual. As it crosses the meridian, it will climb so very high in the sky that from central Florida and southern Texas it will be seen overhead. For watchers in Miami or Brownsville, the moon will even pass north of the point directly overhead (the zenith).
