#Sapce #Update #China confirms that it's #Tiangong space station will host its first foreign astronaut: a #Pakistani, aboard Shenzhou-24. As @Space_Station nears retirement, Beijing is expanding its space diplomacy. #India has reason to take note.

In this week's #Parallax, I look at how #Space is back in the language of national ambition with Trump's new proclamation. The goings-on in India, including the unpalatable spat and why the sector may not wait for those who fall behind... Link: shorturl.at/NaOQx

#Space #Update An experimental inflatable structure designed as a precursor to future expandable space habitats has completed its near-space flight test, taking #Akashalabdhi a step closer to demonstrating tech for building infra in space. Full story: shorturl.at/589zT

#Space #India #NVS03 is a step towards restoring NavIC. But years of failures & component dependence have exposed challenges of sustaining navigation sovereignty. 20yrs after it was first approved, #NavIC is still a strategic ambition, not an operational reality for India…

In this week's #Parallax, Chethan Kumar writes, maybe it’s time to go beyond the narrow lens and look at cities through science. Not because science has all the answers to urban problems, but because it can help us understand why cities behave the way they do… timesofindia.indiatimes.com/…

In this week's #Parallax, Chethan Kumar argues that IISc should be Isro’s #JPL! India’s space ambitions need a stronger bridge between fundamental research & space missions. @isro & @iiscbangalore already have the foundations. India now needs to build on them. timesofindia.indiatimes.com/…

Told you so! ITBP DG Shatrujeet Singh Kapur confirms several face-offs between Chinese & Indian troops in Arunachal, including Taksing, which are still continuing. The face-offs were even taking place when Chinese President Xi Jinping visited Delhi for BRICS. #IndiaChinaBorderRow

At work, “final” is a moving target, “soon” is a state of mind, and “yes” may mean “I heard you”. Long before #GenZ redefined emojis, we've all encountered the word-bending OGs.

In this week's #Parallax, Chethan Kumar argues that India must change its slogan to #MadeBYIndia from #MadeINIndia, lest it wants to become a nation that manufactures the future without owning it. It must learn to look at milestones like a marathon runner, not a PR agency! timesofindia.indiatimes.com/…

#Space #Update In a first, scientists have jointly analysed observations of the same solar eruptions captured by India's #AdityaL1 & #Proba3 by @esa, offering fresh insights into how these powerful events evolve close to the Sun. 1/n Pic: AI, for representation

@IIABengaluru researchers combined observations from the Visible Emission Line Coronagraph (VELC) on Aditya-L1 & #ASPIICS coronagraph aboard Proba-3 to study two coronal mass ejections (CMEs) recorded on Sept 14 and 16, 2025. 2/n

The study, published in Astronomy & Astrophysics, measured the eruptions’ mass, density and energy, providing new constraints on the physical processes that shape them in the Sun's inner corona. 3/n

#CMEs are large eruptions in which the Sun ejects vast quantities of magnetised plasma into space. When directed towards Earth, they can disturb its space environment and affect satellites and other space-based systems… 4/n

…Understanding their early evolution is crucial to improving our knowledge of these events and their potential consequences. Observing CMEs close to Sun has remained challenging. 5/n

Earlier space-based coronagraphs couldn’t fully track early evolution of faint eruptions, leaving scientists with limited info on how their energy is divided between motion, heat and magnetic fields. 6/n

The two missions offer complementary capabilities. VELC uses spectroscopy to study the solar corona, including the temp & density of its gas. ASPIICS captures images of corona using visible light and a green emission line. 7/n

Combining these observations allows scientists to cross-check estimates of CME properties using different methods. As per Isro, the two instruments share a common field of view in the low corona. 8/n
