Relatively small structures on the Sun could help govern the solar wind.
Why it matters: Solar wind batters the Earth's magnetic field, and strong solar storms can disrupt satellites and even power grids on the planet. Learning more about how they work will help researchers forecast it in the future.
The first flight planned for NASA's Space Launch System rocket hangs in the balance as the space agency reckons with a major test that didn't go as planned this weekend.
Why it matters: The billions of dollars over-budget SLS is key to NASA's plans to send people to the surface of the Moon by 2024 and for the agency's deep space exploration goals for years to come.
The effects huge constellations of satellites could have on astronomy are starting to come into focus, and astronomers are grappling with what this industrialization of space could mean for the future of their field.
The big picture: Companies like SpaceX and Amazon have plans to launch thousands of internet-beaming satellites to orbit in the coming years.
The finest details of galaxies — from star explosions to halos of dust — are emerging via new techniques that allow scientists to peer deep into these cosmic behemoths.
Why it matters: How galaxies form, grow and change is key to understanding the evolution of the universe as a whole.
Virgin Orbit's LauncherOne rocket reached space and successfully deployed 10 payloads for NASA's Launch Services Program on Sunday, Richard Branson's company announced.
Why it matters: Per Axios' Miriam Kramer, Virgin Orbit is one of several private spaceflight companies aiming to capitalize on what they believe is a boom in demand for small spacecraft launches.
NASA staged a ground test of its Space Launch System rocket Saturday. The test — which was expected to see the four engines of the core stage of the huge rocket fire for eight minutes — ended after a little more than a minute.
Why it matters: The SLS, which is years behind schedule, is key to NASA's plans to send people to deep space destinations like the Moon.
Blue Origin's New Shepard space system, designed to one day take paying customers to suborbital space, took flight from Texas on Thursday for an uncrewed test.
Why it matters: The company — founded by Amazon's Jeff Bezos — is inching closer to launching its first customers.
Redstone Arsenal in Huntsville, Alabama will serve as the headquarters for U.S. Space Command, the Air Force announced Wednesday, after a hard-fought lobbying campaign.
The big picture: The U.S. military relies on space assets for all types of warfighting, and Space Command — which was established in 2019 as a unified combatant command — is designed to help protect those assets, treating space as a theater of war in much the same way air and sea are.
Scientists have discovered a rocky “super-Earth” planet in an ancient star system that likely formed 10 billion years ago, only a few billion years after our Milky Way galaxy came to be.
Why it matters: The newfound planet likely can't support life, but in general, researchers think older planetary systems have better odds of possibly harboring life because they're long-lived.
NASA's InSight lander on Mars and the Juno orbiter at Jupiter have new leases on life.
Why it matters: The spacecraft are expected to continue gathering data about their respective planetary targets during their newly extended missions, allowing scientists to learn more about seismic activity on Mars and turn their attention to the moons of Jupiter.
