Reentry of International Space Station (ISS) batteries into Earth’s atmosphere

$1:
The European Space Agency (ESA) Space Debris and Independent Safety Offices are closely monitoring the reentry of a pallet of used ISS batteries and calculating estimates for when and where the reentry will occur.

The batteries, nine in total, were released on 11 January 2021 and will undergo a natural reentry, which is now predicted for around 18:56 CET on 8 March +/- 0.4 days.

The total mass of the batteries is estimated at 2.6 metric tonnes, most of which may burn up during the reentry. While some parts may reach the ground, the casualty risk – the likelihood of a person being hit – is very low.

Say 'Cheese,' Universe: Scientists Complete Construction of the Biggest Digital Camera Ever

$1:
Nine years and 3.2 billion pixels later, it is complete: the LSST Camera stands as the largest digital camera ever built for astronomy and will serve as the centerpiece of the Vera Rubin Observatory, poised to begin its exploration of the southern skies.

The Rubin Observatory’s key goal is the 10-year Legacy Survey of Space and Time (LSST), a sweeping, near-constant observation of space. This endeavor will yield 60 petabytes of data on the composition of the universe, the nature and distribution of dark matter, dark energy and the expansion of the universe, the formation of our galaxy, our intimate little solar system, and more.

The camera will use its 5.1-foot-wide optical lens to take a 15-second exposure of the sky every 20 seconds, automatically changing filters to view light in every wavelength from near-ultraviolet to the near-infrared. Its constant monitoring of the skies will eventually amount to a timelapse of the heavens; it will highlight fleeting events for other scientists to train their telescopes on, and monitor changes in the southern sky.
