NASA’s $5 billion Europa Clipper mission may not be able to handle Jupiter’s radiation

NeRD

A highly anticipated NASA astrobiology mission is troubleshooting a serious issue just months before its planned liftoff. The Europa Clipper spacecraft is scheduled to launch this October atop a SpaceX Falcon Heavy rocket. The robotic explorer will embark upon a $5 billion mission to assess the potential of Europa, an ice-covered ocean moon of Jupiter, to support life as we know it. But that launch date, and the probe’s ability to carry out its ambitious mission, may now be in peril: Mission team members have discovered a problem with Clipper’s…

FAA investigating SpaceX Falcon 9 rocket anomaly

NeRD

The U.S. Federal Aviation Administration (FAA) is requiring an investigation into the recent anomaly suffered by a SpaceX Falcon 9 rocket. The issue occurred on Thursday night (July 11), during the launch of 20 Starlink internet satellites from Vandenberg Space Force Base in California. The Falcon 9‘s upper-stage engine failed to complete its second burn as planned, and the spacecraft were deployed into a lower-than-intended orbit as a result, according to SpaceX. SpaceX is looking into the nature and cause of the anomaly, under the supervision of the FAA. “The…

Galactic penguin honors the 2nd anniversary of James Webb Space Telescope’s 1st images

NeRD

To celebrate two years since the James Webb Space Telescope (JWST) started sending images back to Earth, NASA has released yet another stunning image taken by the revolutionary space telescope. The second-anniversary JWST image shows two interacting galaxies that make up a single object called Arp 142, which appears like a cosmic penguin with its cosmic egg. Fittingly for a celebration of the JWST’s two years of science results, the new image is a two-for-two. Arp 142’s Penguin and Egg scene comprises two interacting galaxies located around 326 million light-years from…

‘Drawn to our planet:’ How spaceflight changed SpaceX Inspiration4 astronaut Chris Sembroski

NeRD

Inspiration4 was the world’s first all-civilian orbital mission, sending a four-person crew skyward atop a SpaceX Falcon 9 rocket. The privately funded commercial mission took place from Sept. 16 to Sept. 18, 2021. Inspiration4 used a SpaceX Crew Dragon spacecraft called “Resilience,” which was commanded by billionaire entrepreneur Jared Isaacman, the founder and CEO of Shift4 Payments. You should get familiar with that name, as he’s also leading the upcoming Polaris Dawn mission, the first effort in the three-flight Polaris program, which is funded and commanded by Isaacman. Isaacman booked…

Cosmic crime scene reveals ancient supernova aftermath of dead star merger

NeRD

The ultimate cosmic “cold case” has lingered for 843 years — and now, space detectives may have solved it at last. In 1181 AD, as the Genpei War raged in Japan, a mystery “guest star” briefly flashed over Asia’s skies. Astronomers had puzzled over the brief event until 2021, when a team of researchers tracked it to its location in the cosmos. Yet, the cause of the event, now designated supernova (SN) 1181, remained shrouded in mystery. That was until a team of scientists used computer modeling and observational analysis…

Perseid meteor shower returns to our skies this month to kick off summer ‘shooting star’ season

NeRD

Anyone gazing at the summer night sky for even a short length of time is likely to spot a few “shooting stars” darting across the sky.  The best meteor display of the summer comes during the second week of August during the annual Perseid meteor shower which, at its peak around the nights of Aug. 11 and 12, is capable of producing 50 to 100 fast, bright meteors per hour for a single observer. Many flaring meteors with trains are seen under good skies. 2024 will be a very good…

Solar maximum is in sight but when will it arrive (and when will we know)?

NeRD

May and June 2024 saw the highest sunspot numbers on the sun since 2002, but is the peak of the solar cycle here yet?  The sun follows an 11-year solar cycle of increasing and decreasing activity. Although not the first astronomer to discover the solar cycle, the solar cycle numbering and naming convention was first introduced in 1852 by Swiss astronomer Johann Rudolf Wolf. Within his new solar cycle numbering system, he set the historic 1755-1766 solar cycle ‘Solar Cycle 1’. By the time of his work, the sun was…

Hear the real stories behind the private space race in new documentary ‘Wild Wild Space’ (video)

NeRD

Forget about those campfire yarns about the infamous land rushes of the Old West in the 19th century as it can’t hold a candle to the crazy, free-for-all stampede for positioning satellite megaconstellations in the erupting sectors of space infrastructure and aerospace firms’ desires for profit in the unfolding era of commercial exploitation. “Wild Wild Space” (a sly nod to the cult ’60s western spy series, “Wild Wild West”) is a new HBO Original documentary directed by Academy Award-winning filmmaker Ross Kauffman (“Born Into Brothels”) which premieres on HBO and…

SpaceX launching direct-to-cell Starlink satellites from California tonight

NeRD

SpaceX plans to launch 20 more of its Starlink satellites tonight (July 10), including 13 with direct-to-cell capabilities. A Falcon 9 rocket carrying the Starlink spacecraft is scheduled to lift off tonight from California’s Vandenberg Space Force Base, during a four-hour window that opens at 10 p.m. EDT (7 p.m. local California time; 0200 GMT on July 11). SpaceX will livestream the action via its X account; coverage will begin about 15 minutes before launch. The Falcon 9’s first stage will return to Earth tonight, if all goes according to…

‘Traffic jams’ around Uranus could solve the mystery of its weak radiation belts

NeRD

Scientists may have solved a lingering mystery surrounding the ice giant Uranus and its weak radiation belts. It’s possible the belts’ weakness is linked to the planet’s curiously tilted and lopsided magnetic field; the field could be causing “traffic jams” for particles whipping around the world. The mystery dates back to Voyager 2’s visit to Uranus in January 1986, far before the probe left the solar system in 2018. The spacecraft found that Uranus‘ magnetic field is asymmetric and tilted roughly 60° away from its spin axis. Additionally, Voyager 2…
