About 16 delegates from the LIGO India Gravitational Wave Astronomy Instrumentation Winter Workshop (hosted by @IUCAAstro) visited the #GMRT on Sunday. They were given a tour of the C03 dish by #GMRT engineer @KaushalBuch2, and the control room by operator @Shriramramane.

We are announcing the Artemis III crew next week. Tune in, because we will also be providing a confidence update on the mission.

Starship stacked on the pad at Starbase

Launch rehearsal complete. During a flight-like countdown, more than 5,000 metric tonnes (11 million pounds) of propellant were loaded on the fully stacked Starship and Super Heavy V3 vehicles for the first time

The view from inside Integrity as recovery forces pop open the hatch…watching the helicopter pass over their shoulders and hearing all the joy, it was as good as it gets.

Artemis II Moon mission complete! ✅✅✅✅✅✅ - Space Launch System rocket launched crew into space - Orion spacecraft kept astronauts safe - Flew around the Moon, observed its far side - New human spaceflight distance record - Crew safely returned to Earth - Inspired the WORLD

Without a requirement to dock in Gateway’s orbit things get more interesting for lunar landers. Say goodbye to NRHO and hello to EPO/CoLA? arstechnica.com/space/2026/0…

Today, we’re launching NASA Force with @USOPM. Returning to the Moon requires restoring core competencies in our civil servant workforce. This program will recruit top aerospace, software, systems, and other critical technical talent for approximately 2-year terms at NASA. This will strengthen in-house engineering excellence, close skill gaps, and deepen partnerships with industry. We’re investing in our people to deepen America’s leadership in space.

🚨Proposed payloads for ISRO's Mars Landing Mission (MLM). #UPDATE MLM will be launched onboard LVM3 and a relay orbiter using PSLV. It will utilize a Sky-Crane (used in NASA's Curiosity & Perseverance rover missions). After Mars Orbiter Mission (MOM) launched in 2013 (more than 12 years ago), ISRO hasn't launched a follow up mission. Such a huge gap is not ideal at all, and MLM won't be launching anytime soon. At least they should have done another orbiter mission (MOM-2) by now, to keep continuous scientific value. #ISRO #MARS 📸 Credit: @Rethik_D

News: the countdown officially started for the rehearsal of our upcoming @NASAArtemis launch. Teams will fuel the rocket and run through a full range of operations to make sure everything is ready for our crewed launch around the Moon. More on the milestones ahead: go.nasa.gov/4aqwY71

Four astronauts. One mission. Hear from the crew of Artemis II, who are preparing for humanity's next lunar journey, in the newest episode of our "NASA's Curious Universe" podcast: bit.ly/498S0qf

Artemis Il is a 10-day flight test of SLS and Orion that will send astronauts farther than any human mission before. It is the next step toward returning Americans to the lunar surface and building sustained missions at the Moon.

LIGO-India presents a special edition of COSMICWEB by @nss_mumbai, released during World Space Week. 📖🔭🌌 It explores gravitational wave science, cutting-edge observatories like LIGO–Virgo–KAGRA, LISA, NANOGrav, Einstein Telescope and their impact on science and society🌀

Tests, milestones, and momentum. Our 2025. 🎬

Large language models and audio transformers are known for mastering human speech and tackling complex tasks. But can they learn the grammar of spacetime (gravitational waves) and the elusive ragas of black holes? I’m excited to share my lab’s latest breakthrough, now published in The Astrophysical Journal Letters (@AAS_Office), where we adapted OpenAI's audio transformer to analyze gravitational-wave data from a rare black hole and learn signal structure directly from spacetime itself. By treating gravitational-wave data like an audio “language,” we applied our in-house machine-learning architecture to listen directly to @LIGO data. We found that GW231123 is indeed a rare “Lite” intermediate-mass black hole merger whose signals show hint of some unaccounted physics. More broadly, this work demonstrates how foundation models developed for human communication can be repurposed to probe the laws of nature. This marks the beginning of a new era of gaining deep insights into the General Theory of Relativity with AI. Big kudos to my team led by Dr. Chayan Chatterjee, PhD students Kaylah McGowan, Suyash Deshmukh, and master's student Nicholas-Tyler Howard for this breakthrough work.

We recently explored humanity's transition to a spacefaring civilization in our latest podcast. Featuring Isaac Arthur, President of the National Space Society, we discuss the practicalities of making space habitation a reality. 🚀🪐✨
