Since the era of meteorological satellites began in the 1950s, continuous remote sensing instrument improvements have elevated Earth science and have significantly increased available atmospheric observations. Likewise, scientists have made considerable advancements in understanding Earth's atmosphere, climate, and environment.
NASA chief says Russia leaving ISS could kick off a space race
NASA Administrator Bill Nelson sits down with CNN's Rachel Crane to discuss what could happen if Russia pulls out of the International Space Station.
The United States has for decades enjoyed a mutually beneficial relationship with Russia that has often served as a powerful symbol of cooperation between the East and West in the post-Cold War era. But that cooperation could soon dissolve, and it has NASA's new chief, Bill Nelson, concerned.
Russian officials are threatening to pull out of the International Space Station , the orbiting laboratory that the US and Russia have jointly operated for two decades, as soon as 2024 in favor of operating an independent space station. Meanwhile, Nelson and the US government want to continue the ISS program through at least 2030.
Space debris tracker LeoLabs raises $65 million
LeoLabs, a private venture that tracks objects and debris in low Earth orbit through a network of radars around the world, raised $65 million in capital in a new fundraising round, the company announced on Tuesday.
"It's a great endorsement of our success to date and where we're headed," LeoLabs CEO Dan Ceperley told CNBC. "We're the largest data provider for [low Earth orbit] in the world now … we've stepped beyond anybody in the public or private [sectors]."
China launches Fengyun-4B weather satellite to orbit | Space
A new Chinese weather satellite launched into orbit Wednesday (June 2) with "complete success," according to one of the participating state contractors.
The Fengyun-4B soared into space aboard a Long March 3B rocket from the Xichang Satellite Launch Center in southwest China, at 12:17 p.m. EDT (1717 GMT, or 12:17 a.m. local time Thursday, June 3).
The new satellite joins a network of geostationary and polar-orbiting Fengyun satellites and will go into geostationary orbit, according to NASASpaceflight.com . The first of the Fengyun series, a low-Earth orbit satellite testing machine called FY-1A, launched in 1988 for a short mission, the report added.
1st commercial astronomy spacecraft Twinkle set for launch in 2024 | Space
The world's first commercial astronomy mission, Twinkle, is gaining traction among exoplanet researchers as it takes steps toward launch in 2024 with funding secured to commence satellite construction early next year.
In 2014, when University College London (UCL) astronomy postdoc Marcell Tessenyi first entertained the idea to develop the world's first commercial astronomy mission, he knew he would have to overcome a lot of resistance. For decades, government-funded space agencies like NASA and the European Space Agency (ESA) were in charge of expensive space telescope projects that took decades to develop and cost billions of dollars.
If a satellite falls on your house, space law protects you — but space junk is a bigger problem |
On May 8, 2021, a piece of space junk from a Chinese rocket fell uncontrolled back to Earth and landed in the Indian Ocean near the Maldives . A year ago, in May 2020, another Chinese rocket met the same fate when it plummeted out of control into the waters off the West African coast . No one knew when or where either of these pieces of space junk were going to hit, so it was a relief when neither crashed on land or injured anyone.
Space debris is any nonfunctional human-made object in space. As a professor of space and society focused on space governance , I've noticed that there are three questions the public always asks when falling space debris gets into the news. Could this have been prevented? What would have happened if there was damage? And how will new commercial companies be regulated as space activities and launches increase exponentially ?
This public company is building satellites to beam broadband coverage from space.
In April, the four-year-old company went public on the NASDAQ exchange through a SPAC merger with New Providence Acquisition Corp. , one in a series of so-called “ blank check ” companies that have formed to take companies public and the second with College Park ties recently. In doing so, it raised $462 million.
“From the very beginning, I wanted to work with a leading university to cultivate top engineering talent and help AST SpaceMobile develop the world’s first space-based cellular broadband network,” he said. “That’s why we partnered with the University of Maryland in College Park and why Dr. Ray Sedwick became one of our first employees.”

Because of an editing error, a Metropolitan Diary item this weekend about a bike ride in Riverdale misstates the author's surnames. He is Malcolm-Wiley Floyd, not Ford.
An article on Page 4 this weekend about the diversity of young assistant conductors incorrectly describes the status of Black music directors of top-tier American orchestras. James DePreist was the music director of the Oregon Symphony from 1980 to 2003; it is not the case that there have been no Black music directors in this group.
