The Neil Gehrels Swift Observatory is scheduled to re-enter Earth's atmosphere on Wednesday after concluding over two decades of space science operations. Projections by the US Space Force established a re-entry timing centered around 3:30 a.m. EST on November 4, subject to an 11-hour window of uncertainty. Surviving hardware is expected to fall predominantly into the ocean, though land areas across Africa, Australia, Southeast Asia, the Americas, and India fall within the descent band. The designated ground track spans latitudes between 20.6°N and 20.6°S, which encompasses major southern Indian urban centers like Mumbai and Bengaluru.

NEW DELHI: A 1.5-tonne space observatory of Nasa is heading back to Earth on Wednesday after working in space for 22 years and some parts of its debris could fall in southern India.Neil Gehrels Swift Observatory was launched in 2004 to explore the universe’s most powerful explosions called gamma-ray bursts. When launched, the spacecraft was a first-of-its-kind multiwavelength observatory designed to study the most powerful explosions in the cosmos using its three telescopes.“US Space Force predicted that the spacecraft will re-enter the atmosphere at approximately 3:30 a.m. EST, Nov. 4, with an uncertainty of 11 hours,” Nasa said on Monday.The US space agency expects most of the spacecraft to burn up as it travels through the atmosphere, but some components are expected to survive re-entry.Most surviving debris is expected to fall into the ocean. However, parts of India, Africa, Australia, Southeast Asia, and Central and South America could fall within the possible re-entry zone.
The enterprise plans to achieve necessary delta-V by deploying water directly as a primary propellant source. Emphasizing the widespread availability of the substance, leadership has anchored the firm's operational roadmap around this specific resource. This strategic pivot focuses on leveraging highly accessible materials to power future space propulsion systems.
The Swift Observatory is completing a decades-long mission studying gamma-ray bursts after solar storms pushed it into an unrecoverable lower orbit. While most of the 3,200-pound spacecraft will disintegrate upon atmospheric re-entry, ground teams are monitoring its descent across equatorial latitudes to track any surviving fragments. Officials assess the overall public safety risk from the uncontrolled descent as minimal.
Selected under NASA’s Astrophysics Pioneers programme, the PUFFINS project aims to launch a specialised 10-inch space telescope by 2030. The venture investigates microscopic interstellar particles measuring under 50 nanometres that influence how light travels across space and assist in creating stars and planets. Led by an Indian Institute of Astrophysics alumna, the multi-institution collaboration will advance cosmic research through ultraviolet spectropolarimetry.
