Mar 27, 2026 Orbital debris in Earth orbit is not adequately described as a static inventory problem. It is a coupled operations–stability problem governed by shell occupancy, collision kernel, breakup severity, and orbital residence time. This paper argues that near-term orbital sustainabili...

Mar 25, 2026 Flood forecasting and predicting the sustaining impacts is vital in protecting people and infrastructure, particularly as increased intensities and frequencies of precipitation events continue to threaten populations globally. Flood inundation maps are an important component of p...

Mar 25, 2026 Spectroscopic observations of the quasar J0950+5128 spanning 22 years show that its broad Hβ emission line displays monotonic radial velocity variations consistent with those expected from a supermassive binary. At the same time, the profile of the broad Hβ line is changing, nece...

Mar 24, 2026 NASA’s Curiosity rover is exploring a 5 km tall sedimentary mound that is hypothesized to record thetransition from a warm and wet (phyllosilicate-rich) to a cold and drier (sulfate-rich) Mars. Evidence ofmagnesium sulfate-bearing rock has shown that Curiosity has crossed through...

Mar 24, 2026 We present a comparison of the two most recent and comprehensive Spitzer phase curve studies -- \cite{dang2025} and \cite{swain2025} -- which report analyses of the Spitzer 4.5 $\mu{m}$ phase curves. The studies employ different approaches for correcting instrument systematics an...
