There may be no life on Mars, but there’s still a lot going on there. The Martian surface is home to different geological process, which overlap and even compete with each other to shape the planet. Orbiters with powerful cameras give us an excellent view of Mars’ changing surface.Continue reading “Dust Devils Have Left Dark Streaks All Over This Martian Crater”
In the coming years, a number of will be sent to space for the purpose of answering some of the enduring questions about the cosmos. One of the most pressing is the effect that solar activity and “space weather” events have on planet Earth. By being able to better-predict these, scientists will be able to create better early-warning systems that could prevent damage to Earth’s electrical infrastructure.
This is the purpose of the Solar Orbiter (SolO), an ESA-led mission with strong participation by NASA that launched this morning (Monday, Feb. 10th) from Cape Canaveral, Florida. This is the first “medium-class” mission implemented as part of the ESA’s Cosmic Vision 2015-25 program and will spend the next five years investigating the Sun’s uncharted polar regions to learn more about how the Sun works.Continue reading “The ESA’s Solar Orbiter, a Mission That Will Chart the Unexplored Polar Regions of the Sun, Just Launched!”
NASA has repeatedly imaged the Martian surface, and sometimes a feature appears that wasn’t there in prior images. That’s what happened when a meteorite survived the plunge through Mars’ thin atmosphere sometime between February and July, 2005. It created this impact crater north of Valles Marineris.Continue reading “A Meteor Smashed Into Mars in 2005, Making this Crater”
A trio of space travelers returned to Earth this morning from the International Space Station, including NASA astronaut Christina Koch, who set a record for the longest single spaceflight by a woman, at 326 straight days. Also coming home was ESA astronaut Luca Parmitano, who has now spent a total of 367 days in space (in two missions), more days than any ESA astronaut in history.
The crew of Expedition 61 also included Russian cosmonaut and Soyuz Commander Alexander Skvortsov, who completed his third mission for a total of 546 days in space, placing him 15th on the all-time time-in-space list.Continue reading “Record-Setting Space Travelers Return to Earth”

Tonight we welcome Dr. Michael Werner and Dr. Peter Eisenhardt, authors of the new book More Things in the Heavens which looks at how infrared astronomy is aiding the search for exoplanets and extraterrestrial life, and is transforming our understanding of the history and evolution of our universe. Included in their book are many spectacular images that have been captured by the Spitzer space telescope over its lifetime.Continue reading “Weekly Space Hangout: February 5, 2020 – “More Things in the Heavens” with Dr. Michael Werner and Dr. Peter Eisenhardt”
It has been suggested that if humanity wants to truly embark on a renewed era of space exploration, one of the key ingredients is the ability to manufacture structures in space. By assembling everything from satellites to spacecraft in orbit, we would eliminate the most costly aspect of going to space. This, simply put, is the sheer expense of escaping Earth’s gravity well, which requires heavy launch vehicles and LOTS of fuel!
This is the idea behind the Space Infrastructure Dexterous Robot (SPIDER), a technology-demonstrator that will be going to space as part of NASA’s Restore-L spacecraft, which is designed to service and refuel a satellite in low-Earth orbit. Once deployed, the SPIDER will assemble a communications antenna and composite beam to demonstrate that space-based construction is possible.Read more
Put “James Webb Telescope launch” into your search engine and you’ll be flooded with links, some reaching back to the ‘scope’s first proposed launch date in 2010. The delayed launch of the space telescope is a running theme in the space community, even though we all know it’s going to be worth the wait. So nobody will be surprised by this latest development in the story of the world’s most anticipated telescope.Continue reading “It Looks Like James Webb’s Launch Date is Going to Slip to July 2021”
NASA’s plan to open up the International Space Station (ISS) to commercial activity is gaining ground. They have a vision for an economy in Low-Earth Orbit (LEO) called the Plan for Commercial LEO Development. According to NASA, they intend to foster economic development in LEO and to drive innovation, all for the benefit of the American economy.
Now they’ve selected Axiom Space of Houston to provide a commercial habitation module for the ISS.Continue reading “NASA is Going to Add a Commercial Module to the Space Station”
Now that the US Space Force’s new uniforms have been eviscerated on social media (that was so last week) it’s up to their new logo to keep the uproar going. The newest branch of the US Armed Forces hasn’t disappointed: their logo looks like the Star Fleet logo from Star Trek, inviting all kinds of rancorous comparisons on the internet.Continue reading “Okay, this Logo Proves that Space Force Should Have Really Been Called Star Fleet”
Located at the heart of the NASA Center for Climate Simulation (NCCS) – part of NASA’s Goddard Space Flight Center – is the Discover supercomputer, a 129,000-core cluster of Linux-based processors. This supercomputer, which is capable of conducting 6.8 petaflops (6.8 trillion) operations per second, is tasked with running sophisticated climate models to predict what Earth’s climate will look like in the future.
However, the NCCS has also started to dedicate some of the Discover’s supercomputing power to predict what conditions might be like on any of the over 4,000 planets that have been discovered beyond our Solar System. Not only have these simulations shown that many of these planets could be habitable, they are further evidence that our very notions of “habitability” could use a rethink.Continue reading “Here’s What the Climate Might Look Like on Proxima Centauri B”
