Ottawa puts $200M into space launch pad in Nova Scotia
The federal government is putting $200 million toward a Canadian-owned launch pad to send satellites into orbit.

NASA's asteroid deflection test for planetary defence even more successful than we thought
The Double Asteroid Redirection Test (DART) mission not only altered an asteroid’s orbit but, for the first time, a new study shows we also successfully changed the asteroids' path around the sun.

Since 2022 he’s made it a yearly tradition to put together a themed project every March 14th, and he’s just put the finishing touches on the 2026 edition.</p>
<p>Generally, [Cristiano] sends in some interesting hardware device that visualizes the calculation of pi, but this year he surprised us a bit by delivering a software project. His <a href="https://cabecao.net/OrbiPi/" target="_blank"><em>Orbital Pi Simulator</em></a> allows you to see what would happen to an orbiting spacecraft if it’s navigation system suddenly believed the value of pi was something different.</p>

If you plug in something significantly higher than 3.14, the orbit becomes elliptical to the point that the craft can

Frage an die Astro-Physik-Bubble:

Welche negativen Konsequenzen hat das Eintreten des Kessler-Syndroms?

Soweit ich verstanden habe, ist der Weltraum dann von der Erde nicht mehr erreichbar. Sonst noch Effekte?

I wonder how much these new #Orbit #Braille displays wil be and how popular they might become.

Spacecraft's impact changed asteroid's orbit around the sun in a save-the-Earth test, study finds

CAPE CANAVERAL, Fla. — An asteroid that NASA used for target practice a few years ago was nudged into a slightly different route around the sun, findings that could help divert a future incoming killer space rock, scientists reported Friday.It's...

What happens to all the man-made #satellites in #Earth's #orbit, of which approximately 15,000 are active, while the #lifespan of a satellite is usually only a few years? L. Revell et al. (2026) express concern in their #Conversation #article that the #throwawaymentality is causing so many decommissioned satellites to finally land in the #outeratmosphere that their #fragments and burnt #dust are #exacerbating #climatechange and #ozonedepletion.
