Watch 2 astronauts replace failed ISS antenna during spacewalk today

NeRD

Two astronauts will do some repair work outside the International Space Station today (Aug. 25), and you can watch the action live. NASA’s Anil Menon and Sophie Adenot of the European Space Agency will conduct a spacewalk today (Aug. 25) to replace a space-to-ground-antenna. The extravehicular activity (EVA) is expected to start around 8:35 a.m. EDT (1235 GMT) and last 6.5 hours. You can watch it live here at Space.com, courtesy of NASA, or directly via the space agency. Coverage will start at 7:00 a.m. EDT (1100 GMT). NASA astronauts…

Pluto losing its planet status may be the best thing that ever happened to solar system diversity

NeRD

Unpopular opinion time, but someone has to say it: I think Pluto being reclassified as a dwarf planet was a great thing for our understanding of the solar system and for the former planet itself. Let me try to convince you, too. First, a little background. The Pluto planet controversy began exactly 20 years ago on Aug. 24, 2006, when the International Astronomical Union (IAU) reclassified the solar system’s (former) ninth planet as a dwarf planet. The reason for the change was the result of the discovery of worlds similar…

Starstruck: NASA Research Shows How Sun’s Ancient History Shaped Earth

NeRD

6 Min Read Starstruck: NASA Research Shows How Sun’s Ancient History Shaped Earth At the center of our solar system, the Sun influences every planet that orbits it. In two recent NASA-funded studies, scientists uncovered how ancient events in the Sun’s history may have helped create Earth’s unique climate and driven previously unexplained climatic shifts.   In new research, scientists at NASA’s SHIELD (Solar Wind with Hydrogen Ion charge Exchange and Large-Scale Dynamics) center — one of NASA’s DRIVE (Diversify, Realize, Integrate, Venture, Educate) Science Centers — trace the trajectory of the heliosphere, the massive bubble created by our Sun that…

How a huge fleet of 17 spacecraft discovered something surprising about solar eruptions

NeRD

A misbehaving coronal mass ejection (CME) that blew out a hidden cloud of charged particles aimed at Earth has been tracked by a record 17 spacecraft spread throughout the solar system, revealing the CME to be surprisingly lopsided. CMEs are “burps” from the sun – huge clouds of magnetized plasma belched out from the sun’s hot outer atmosphere, the corona, by the energy resulting from a solar flare. The magnetized CME cloud then expands out into the solar system, and the charged particles that the cloud contains are a significant…
