NASA’s Roman mission will probe galaxy’s core for hot Jupiters, brown dwarfs

When it launches in the mid-2020s, NASA’s Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme…

Boeing Curbed Rocket Test Over Hydraulics Issue, NASA Says

Boeing’s test of the largest rocket in U.S. history ended earlier than expected on Jan. 16 because a hydraulic-system setting exceeded a preset limit, dealing another setback to the company’s space ambitions. From a report: The first firing of all four RS-25 engines on the Space Launch System rocket ended just 67.2 seconds into the planned eight-minute test. The so-called hot…

Genesis of blue lightning into the stratosphere detected from ISS

Dark clouds, the smell of rain on a hot sidewalk, the flashes of intense light followed by a loud crackling and then a low, rolling thunder—who doesn’t love a good summer thunderstorm? We’ve all seen one, heard one, or been completely soaked by one. But how much do we really know about this weather phenomenon?

Striped brown dwarf looks a lot like Jupiter

The surface features of brown dwarfs – objects midway in mass between planets and stars – can’t be seen. But researchers have found a way to reveal Jupiter-like stripes and bands in the atmosphere of the closest brown dwarf, Luhman 16B.

‘Major Component Malfunction’ Ends SLS Rocket Test Early. NASA Considers New Timeline

“NASA’s rocket charged with taking the agency back to the moon fired its four main engines Saturday afternoon, but the test in Mississippi was cut short after a malfunction caused an automatic abort,” reports Florida Today… “We did get an MCF on engine four,” a control room member said less than a minute into the test fire, using an initialism that…

Watch NASA Test-Fire Its SLS Mega-Rocket Engines

“The date is set,” NASA tweeted yesterday, thanking its partners Boeing Space and Aerojet Rocketdyne for Saturday’s “hot fire” test of the SLS’s core stage. “One of NASA’s main goals for 2021 is to launch Artemis I, an uncrewed moon mission meant to show the Orion spacecraft and Space Launch System rocket can safely send humans to our lunar neighbor,” reports…

FTC Settlement With Ever Orders Data and AIs Deleted After Facial Recognition Pivot

The maker of a defunct cloud photo storage app that pivoted to selling facial recognition services has been ordered to delete user data and any algorithms trained on it, under the terms of an FTC settlement. TechCrunch reports: The regulator investigated complaints the Ever app — which gained earlier notoriety for using dark patterns to spam users’ contacts — had applied…
