Cloud-free crop maps foster sustainable farming
Sunday, 24 January 2021 12:00
The rapidly rising global population, sustainability and climate change are among the challenges the agriculture sector faces in the business of producing food. Fortunately, information from satellites can help. A new commercial service – the first in the world – cleverly combines radar data from Copernicus Sentinel-1 and optical data from Copernicus Sentinel-2 to offer daily maps of field-scale crop biomass. Importantly, these maps are completely unimpeded by cloud cover. This new service allows farmers to better monitor and assess the growth of their produce, and, ultimately, make more effective decisions.
Phase Four launches first plasma propulsion systems

WASHINGTON — Electric propulsion company Phase Four flew its first plasma thrusters on two spacecraft that were part of a SpaceX dedicated rideshare launch Jan. 24.
Phase Four said its Maxwell plasma propulsion systems were on two of the 143 spacecraft launched on the Transporter-1 mission.
Our world is losing ice at record rate
Sunday, 24 January 2021 10:45
A research team – the first to carry out a survey of global ice loss using satellite data – has discovered that the rate at which ice is disappearing across the planet is speeding up. The findings also reveal that 28 trillion tonnes of ice was lost between 1994 and 2017 – equivalent to a sheet of ice 100 metres thick covering the whole of the UK.

SpaceX on Sunday launched its Falcon 9 rocket carrying a record number of satellites on board, the private space company said.
The rocket successfully launched from Cape Canaveral, Florida at 10:00 am (1500 GMT), 24 hours after its initial take-off had been scrubbed due to bad weather.

All four planets orbiting the star HR 8799 were identified via direct imaging - a feat made possible only because of the planets' large sizes and their wide orbits. Planetary systems with these characteristics often have difficulty holding themselves together under all of the gravitational influences involved. But could the HR 8799 system somehow stay intact?

A new international study led by astrophysicist Eric Agol from the University of Washington has measured the densities of the seven planets of the exoplanetary system TRAPPIST-1 with extreme precision, the values obtained indicating very similar compositions for all the planets. This fact makes the system even more remarkable and helps to better understand the nature of these fascinating worlds.
