3-fs-resolved UV/XUV photoelectron spectroscopy in gas phase

Scientists have achieved a temporal resolution of 3 femtoseconds (fs) in ultraviolet/extreme ultraviolet (UV/XUV) photoelectron spectroscopy in the gas phase. This breakthrough allows for the observation of ultrafast processes in molecular dynamics with unprecedented precision. The technique combines UV and XUV pulses to excite and probe electrons, respectively, opening new avenues for understanding chemical reactions and structural changes at fundamental timescales.

Katalyst Space's LINK Mission Will Not Boost NASA's Swift Satellite

Katalyst Space's LINK mission, designed to raise the orbit of NASA's Neil Gehrels Swift Observatory, will not proceed with the planned 'boost' maneuver. The decision was announced jointly by NASA and Katalyst Space due to an ongoing attitude control issue with the commercial spacecraft. Although the primary goal of extending Swift's scientific lifespan through orbital elevation will not be met, the LINK mission will still attempt to conduct rendezvous and proximity operations with the observatory.

The Neil Gehrels Swift Observatory, launched in 2004, is a multi-wavelength mission dedicated to studying gamma-ray bursts (GRBs) and other high-energy transient phenomena. It has been instrumental in understanding the nature of these extreme cosmic events, as well as in detecting supernovae and characterizing black holes. Extending its mission through an orbital boost would have allowed its valuable observations to continue for an additional period.
