SpaceX fired a Falcon 9 rocket off a launching stand in California at sunset Thursday, producing a twilight sky show visible as far away as Texas as the mission delivered 53 more Starlink internet satellites into orbit.
Everybody’s heard of methane. It’s a major part of the atmosphere in places like Uranus and Neptune. On Earth, it’s also part of our atmosphere, where it works to warm things up. Some of it gets there from natural causes. But, a lot of it comes from industrial super-emitters and other human-caused processes. That’s not good because too much methane works, along with other greenhouse gases (like carbon dioxide, or CO2) to “over warm” our atmosphere.
SpaceX lit the engines of its powerful Falcon Heavy rocket on Thursday (Oct. 27), paving the way for a liftoff early next week.
Russia’s Progress MS-21 resupply spacecraft is on course for an automated docking with the International Space Station at 10:51 p.m. EDT (0251 GMT) to deliver more than 2.7 tons of cargo to the lab’s seven-person crew.
Less than a year after it went to space, the James Webb Space Telescope (JWST) has already demonstrated its worth many times over. The images it has acquired of distant galaxies, nebulae, exoplanet atmospheres, and deep fields are the most detailed and sensitive ever taken. And yet, one of the most exciting aspects of its mission is just getting started: the search for evidence of life beyond Earth. This will consist of Webb using its powerful infrared instruments to look for chemical signatures associated with life and biological processes (aka. biosignatures).
A few years from now, a small capsule will enter Earth’s atmosphere and float to the surface under a parachute. The parachute will likely be radar-reflective so that it can be easily tracked. It may land in Australia’s outback, a popular spot for sample returns. Scientists will take it to a sterilized, secure lab and carefully open it. Inside, there’ll be rock samples from Mars collected by the Perseverance Rover.

There’s still a raging debate in some circles as to whether Pluto should be a planet or not. Ask an astronomer, and their typical answer would be something like – if Pluto is a planet, then there are plenty of other bodies out there in the solar system that should be considered one too. One of those is Haumea, a little explored rock in the Kuiper belt that is one of the strangest large objects out there. Now, a team from NASA has a new idea as to how it got that way.
