Using its second-to-last Antares rocket with Russian engines before a redesign to rely on all-U.S. propulsion, Northrop Grumman sent a Cygnus supply ship into orbit from Virginia on Monday to deliver spacewalk equipment, experiments, and fresh treats for the crew on the International Space Station.
Planets and stars are almost like parents and children, a new study suggests: The smaller bodies keep the larger ones active, helping them stay young for longer.
A computer simulation of TRAPPIST-1e shows how the James Webb Space Telescope could help the search for habitable alien worlds.

Since February 2019, NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander has been making the first-ever measurements of tectonics on another planet. The key to this is InSight’s Seismic Experiment for Interior Structure (SEIS) instrument (developed by seismologists and geophysicists at ETH Zurich), which has been on the surface listening for signs of “marsquakes.” The dataset it has gathered (over 1,300 seismic events) has largely confirmed what planetary scientists have long suspected: that Mars is largely quiet.
Ever since astronomers first detected ultra high energy neutrinos coming from random directions in space, they have not been able to figure out what generates them. But a new hypothesis suggests an unlikely source: the mergers of black holes.
The last total lunar eclipse until 2025 will turn the moon a blood-red hue on Tuesday, Nov. 8, but exactly when you should look up depends on where you are.

China launched a high-power communications satellite Saturday on a mission to connect airline passengers, maritime vessels, and other users across China, Southeast Asia, and remote routes between the Asia-Pacific region and North America.
The rapid decline of the British-Irish Ice Sheet thousands of years ago may hold lessons for how melting ice sheets in Greenland and Antarctica will influence sea-level rise in the future.
We're unprepared for when E.T. reaches out to us. A team of experts is determined to change that.
If you surfed the web this morning, you may have seen news of the latest existential threat to humanity: a “planet killer” asteroid named 2022 AP7. Luckily for us 2022 AP7 “has no chance to hit the Earth currently”, according to Scott Sheppard at the Carnegie Institution for Science.

The first test flight of Boeing’s Starliner crew capsule with astronauts has been delayed from February to April 2023, moving the mission after a busy stretch of crew and cargo missions to the International Space Station, and allowing more time for engineers to address problems discovered on an unpiloted test flight earlier this year, NASA said Thursday.
A fire alarm on Earth prevented the launch of Northrop Grumman's NG-18 cargo ship for NASA on Nov. 6.
NASA named 18 space agencies, organizations and individuals who will watch the Orion spacecraft as it flies around the moon, after launching with Artemis 1 no earlier than Nov. 14.

Northrop Grumman is set to launch the penultimate flight of its current Antares rocket configuration — with Russian engines and a Ukrainian first stage structure — to begin a resupply mission Sunday delivering more than four tons of cargo to the International Space Station.
Historical data about solar storms carved in trees, and it’s a bit worrying. Falcon Heavy’s back after 40 months of absence. There’s a meteor shower and a total lunar eclipse in the coming days. And JWST gave us yet another version of Pillars of Creation.
Tragically sometimes stars engulf their own planets. While most stars are able to quickly cover up the evidence for their crime, a new study by astronomers has revealed that in some cases the evidence can linger for up to two billion years.
Iran's Revolutionary Guard successfully launched a new rocket capable of sending satellites into orbit on Saturday (Nov. 5).
