This US-Indian Satellite Will Monitor Earth’s Changing Frozen Regions

NeRD

Satellite imagery shows a portion of East Antarctica on Jan. 9, 2022, before icebergs calved off the Glenzer and Conger glaciers. NISAR will observe nearly all of the planet’s land and ice surfaces twice every 12 days, monitoring Earth’s frozen regions, known as the cryosphere. USGS Much of the Glenzer and Conger glaciers had collapsed by March 23, 2022, spawning numerous icebergs, as shown in this satellite image. NISAR will document such changes around the globe, and its geographic coverage of Antarctica will be the most extensive for a radar…

Advice from NASA Mentors to Students Starting Their Careers

NeRD

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) GSFC summer interns NASA is celebrating National Mentoring Month by recognizing the importance of mentors to students and young professionals whose careers are beginning to take off. Mentors help their mentees gain real-world experiences, make valuable connections, and find the types of roles best suited to their strengths and skills. To learn more about early career takeaways, we spoke to three NASA mentors: Renita Fincke, NASA biomedical research projects engineer at Johnson Space Center in Houston; Wade Sisler, executive…

How giant impacts shaped the formation of the solar system’s planets

NeRD

If you want to build a planet, you’re going to have to get your hands dirty. That’s the lesson from a recent paper, which outlines just how vital giant impacts are to the formation of planets. Astronomers still aren’t exactly sure how planets get their start. Initially, star systems are just clouds of gas and dust swirling around a newborn star. Some of that gas coalesces to form the seeds of planets. Over millions of years, trillions of those seeds merge, becoming ever larger and attracting their neighbors. At a…

1st ‘interstellar tourism campaign’ urges aliens to visit Lexington, Kentucky

NeRD

Hey, aliens! Lexington, Kentucky would be a good place to spend your next deep-space vacation. This was the message that a group of Kentucky scientists, linguists and scholars recently beamed at the TRAPPIST-1 system, which lies 40 light-years from Earth and harbors multiple potentially habitable planets. The missive represented the very first interstellar travel advertisement, according to VisitLEX, the group behind the effort. Related: The search for alien life VisitLEX’s tourism team at the Lexington Convention and Visitors Bureau partnered with the Cornett ad agency to devise a playful campaign…

Stuck valve may have doomed private Peregrine moon lander mission, Astrobotic says

NeRD

Astrobotic has homed in on a potential cause for the problems plaguing its Peregrine moon lander. Peregrine launched early Monday morning (Jan. 8) atop United Launch Alliance’s (ULA) new Vulcan Centaur rocket, with the goal of becoming the first private spacecraft to land softly on the moon.  That dream was dashed, however, by a propellant leak that sprang up shortly after Peregrine deployed from the rocket’s upper stage. Astrobotic has been troubleshooting and analyzing the issue ever since, and the company may now know what happened. “Astrobotic’s current hypothesis about…

10 Years Ago: The First Operational Cygnus Cargo Mission to the Space Station

NeRD

To replace the cargo and crew transportation services to and from the International Space Station following the retirement of the space shuttle in 2011, the United States developed a novel approach to procure those services from American commercial entities. On Jan. 9, 2014, Orbital Sciences Corporation, one of two companies selected initially to provide cargo transportation services, launched the first operational mission of its Cygnus spacecraft. During its one-month stay at the space station, the onboard Expedition 38 crew unloaded its cargo and then filled it with trash and unneeded…

Hubble Finds Weird Home of Farthest Fast Radio Burst

NeRD

5 min read Hubble Finds Weird Home of Farthest Fast Radio Burst A NASA Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble’s sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging. They existed when the universe was only 5 billion years old. FRB 20220610A was first detected on June 10, 2022, by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia. The European Southern Observatory’s Very Large Telescope…

A “Green Monster” Lurks in Star’s Debris

NeRD

For the first time, astronomers have combined data from NASA’s Chandra X-ray Observatory and James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A). This work has helped explain an unusual structure in the debris from the destroyed star called the “Green Monster,” because of its resemblance to the wall in the left field of Fenway Park.
