Jupiter’s moon Europa, an icy world with a subsurface ocean that interests astrobiologists, may actually be hot enough to melt the interior rock and create volcanoes on the ocean floor. Plus, Ryugu, giant planets, fossil discoveries, Martian glaciers, and this week’s What’s Up!
There were only three launches this past week — an SBIRS satellite for the United States government, an ocean-monitoring satellite for the Chinese government, and the very successful launch of a Virgin SpaceShip suborbital plane. Plus, this week in rocket history, we look back at the first crewed Skylab mission.
A new super-Earth has been discovered that has an extremely hot surface temperature, and this planet could be a boon for studying the atmospheres of rocky exoplanets. Plus, our daily news roundup, climate change, and how a petrified tree on Earth might help us hunt for fossils on Mars.
A radio-loud magnetar first observed in March 2020 suffered an apparent identity crisis, behaving like a pulsar until gradually settling into magnetar-like emissions in July. Plus, Mars’ moon Phobos, Jupiter’s moon Ganymede, and an interview with SETI Institute scientist Veselin Kostov about last week’s sextuple star system.
Join us for this week’s Rocket Roundup with host Annie Wilson as we look back at the launches and missions that happened last year, including test flights and first flights, mission launches and discoveries, and all the people in space (and their zero-gravity indicators). Plus space toilets.
USGS volcanologists and seismologists have been working around the clock to collect data on Kīlauea’s latest eruption after two years of dormancy. Plus, all the volcano news you can handle, as well as a meteorite, an asteroid, and a comet, oh my!
