SpaceX is slated to send four new crewmembers to the International Space Station on Friday.
Why it matters: This will mark the third crewed flight for the company, which has big plans to one day launch people to the Moon and eventually to Mars.
Starting Tuesday, the Hubble Space Telescope will pass almost directly over St. Petersburg several nights this week.
What to look for: Heavens Above, a nonprofit satellite prediction site, says the HST will look like a bright star slowly moving from west to east.
NASA successfully piloted the Ingenuity Mars helicopter for its first experimental flight on Monday, briefly hovering the aircraft as NASA's Perseverance rover collected data.
Why it matters: Ingenuity's short flight marks the first time a human-built aircraft has flown on a world other than Earth, opening the door to new means of exploring planets far from our own.
NASA announced Friday it has awarded Elon Musk's SpaceX a $2.89 billion contract to build a spacecraft that will carry astronauts to the Moon's surface.
Why it matters: NASA hopes to land astronauts on the Moon by 2024, which if successful, would be the first time since the last Apollo mission. SpaceX beat out Jeff Bezos' Blue Origin and defense contractor Dynetics for the contract.
A new era in monitoring compliance of environmental regulations is quickly approaching, signaled in part by plans announced Thursday to deploy a network of satellites that can pinpoint sources of of methane and carbon dioxide emissions.
Why it matters: The new nonprofit, known as Carbon Mapper, aims to launch its first satellite in 2023 that can detect methane super-emitters and track carbon emissions. If successful, it could transform the way policymakers regulate greenhouse gas emissions and also generate a wealth of data for public use.
NASA's little Ingenuity helicopter on Mars will have to wait a bit longer to take to the Martian skies for the first time after a problem was detected during a test last week.
Why it matters: If the eventual flight is successful, this will mark the first time an aircraft has flown on a world other than Earth, opening the door to a new type of planetary exploration.
Scientists have discovered the three fastest spinning "failed stars" yet found, suggesting there might be a speed limit to how fast they can rotate.
The big picture: These objects — called brown dwarfs — are thought to be "failed stars" that didn't collect enough mass to ignite fusion in their cores needed to be considered a star and too large to be a gas giant planet like Jupiter.
As humanity stretches into orbit and beyond, experts are still grappling with how rights afforded to workers on Earth apply to those living in space.
Why it matters: In order to create businesses and perhaps societies in space — where the biological necessities for sustaining human life, like air and water, aren't readily available — there will need to be fundamental rights agreements to guarantee laborers aren't exploited.
NASA announced Saturday it rescheduled its Ingenuity Mars helicopter's first experimental flight, originally planned for Sunday.
The latest: "During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a 'watchdog' timer expiration," NASA said in a statement. "This occurred as it was trying to transition the flight computer from ‘Pre-Flight’ to ‘Flight’ mode."
