An Earth-facing #SolarFlare has just launched a coronal mass ejection towards Earth. The flare is only moderate in size, but well placed for the eruption to hit us. We’re not talking about anything extreme, but simulations will give a better idea of the likely impact timings and effects soon.

“It is fundamentally impossible to ever establish alien life at some threshold odds ratio, Ocrit, unless we deem the prior probability that some as-yet-undiscovered natural process could explain the event is less than 1/(1+Ocrit).”

Pune-based startup Astrophel Aerospace test firing of its indigenously developed, reusable Potentia C1U semicryogenic engine. They have signed an MoU with ISRO towards their test campaign, and intend to develop a partially reusable rocket for small satellites.

A Centaur upper stage launched by an Atlas booster for the Surveyor 2 mission in 1966 escaped the solar system in 2021. It was spotted by our asteroid alert system, and could be detected by other civilisations in direction of Pegasus constellation.

UPDATE on our new interstellar friend #A11pl3Z:
Citizen scientist Sam Deen has found earlier observations of from June 25-28, from the ATLAS telescope!

Now with 6 days' worth of data, the eccentricity of A11pl3Z's trajectory is narrowed down to e=10.4 ± 1.1!
... that's undoubtedly interstellar.

Can get lost finding events in Aditya L1 data better to find data for known events.

So many scenarios for exoplanets in this environment

Placing the crew module from Saturday’s flight on top of the LVM3 used for OneWeb launch shows what ISRO’s Human Rated Launch Vehicle will look like.
