Nasa's Hi-C Flare mission, with advanced instruments from Marshall Space Flight Center, captures solar flares. The mission, led by Sabrina Savage, successfully launches sounding rockets to observe and analyze M-class flares, utilizing innovative solar flare prediction algorithms and COOL-AID data analysis by Amy Winebarger."}

ULA launch director Tom Heter III on Tuesday announced that the launch of Atlas V and Starliner which was scheduled for today, have been postponed. Nasa in a post on X (formerly Twitter) also confirmed the postponement of the launch. Indian-origin astronaut Captain Sunita Williams and her colleague, veteran Nasa astronaut Butch Wilmore, were part of the mission to the International Space Station (ISS).

The gumdrop-shaped CST-100 Starliner with two astronauts aboard was due for liftoff at 10.34pm (8.04am IST Tuesday) from Nasa's Kennedy Space Center in Florida, carried atop an Atlas V rocket furnished by the Boeing-Lockheed Martin joint venture United Launch Alliance (ULA).

Nasa's GEDI on ISS utilizes lidar to study Earth's forests in 3D, providing insights into canopy height, vegetation density, climate change responses, carbon sequestration, and habitat changes for groundbreaking discoveries.

After years of delays and stumbles, Boeing is finally poised to launch astronauts to the International Space Station for Nasa. It's the first flight of Boeing's Starliner capsule with a crew on board, a pair of Nasa pilots who will check out the spacecraft during the test drive and a weeklong stay at the space station.

The inaugural Polaris Dawn mission, the first of the program's three human spaceflight missions, is slated for launch no earlier than summer 2024. Supporting the crew at an altitude of 700 km above Earth, the newly developed Extravehicular Activity (EVA) suit will provide vital support during the historic first-ever commercial astronaut spacewalk.

US health officials cautioned that dairy workers remain susceptible to contracting the H5N1 bird flu virus, which is circulating among dairy herds. In a letter to the New England Journal of Medicine authored by Tim Uyeki from the US Centers for Disease Control and Prevention and Texas health officials, workers were advised to utilize protective gear.

NASA's Deep Space Optical Communications (DSOC) technology, demonstrated aboard the Psyche spacecraft, has achieved a groundbreaking milestone by successfully transmitting engineering data over 140 million miles using optical communication. Although Psyche primarily uses radio frequency for data transmission, this feat showcases the potential of optical communication for future missions, including sending humans to Mars.

A new model could explain the "cosmic glitch" at the edge of the expanding universe, where gravity weakens by about a per cent, according to new research. The widely accepted model of gravity comes from Einstein's theory of general relativity, which has been confirmed through multiple tests and experiments.

Astronomer Frederick Walter suggests gamma-ray bursts could have exterminated extraterrestrial civilizations, potentially explaining the lack of contact with alien life. Despite the threat, Earth's chances of being hit are low due to the rare, directed nature of GRBs.

A recent study has shed light on the origin of the near-Earth asteroid known as Kamo’oalewa, revealing that it likely originated from the Giordano Bruno crater on the moon's far side. This discovery marks the first time astronomers have traced a potentially hazardous asteroid back to a specific lunar crater, offering new perspectives on the dynamics between Earth and its celestial neighbor.
