ground water amount and distribution, data by #NASA #GRACE and #GRACEFO, video by me, from 02/2003 to 12/2024

ever since 2015 it became serious throughout Europe.

🚨 New header picture 🖼️

The GRACE Follow-On satellite mission uses technology developed for @LISA to observe critical indicators of climate change through changes in the Earth's gravitational field.

The mission uses a laser interferometer with nanometer accuracy between two satellites in Earth orbit. Researchers at @mpi_grav are not only involved this mission, but also in future similar missions due to their expertise in the design of laser interferometers.

Satellite gravimetry

Satellite gravimetry measures the Earth's gravitational field from low Earth orbit. GRACE Follow-On uses LISA technology to monitor critical indicators of climate change caused by changes in the Earth's gravitational field. The mission uses a laser interferometer with nanometre accuracy between two satellites. Because of their expertise, researchers at the AEI are involved in the design of the laser interferometers for future similar missions.

Die Satellitenmission GRACE Follow-On beobachtet mittels Technologie, die für @LISA entwickelt wurde, kritische Indikatoren des Klimawandels durch Veränderungen im Gravitationsfeld der Erde.

Die Mission setzt dazu ein Laserinterferometer mit Nanometer-Genauigkeit zwischen zwei Satelliten in einer Erdumlaufbahn ein. Forschende am @mpi_grav sind aufgrund ihrer Expertise nicht nur an dieser Mission, sondern auch am Design der Laser-Interferometer von zukünftigen ähnlichen Missionen beteiligt.

Satellitengravimetrie

Die Satellitengravimetrie vermisst das irdische Schwerefeld aus der niedrigen Erdumlaufbahn. GRACE Follow-On beobachtet mittels LISA-Technologie kritische Indikatoren des Klimawandels durch Veränderungen im Gravitationsfeld der Erde. Die Mission setzt dazu ein Laserinterferometer mit Nanometer-Genauigkeit zwischen zwei Satelliten ein. Forschende am AEI sind aufgrund ihrer Expertise am Design der Laser-Interferometer von zukünftigen ähnlichen Missionen beteiligt.

New profile picture: GRACE Follow-On is a tandem of two satellites orbiting the Earth 220 kilometers apart in the same orbit 490 kilometers above the ground. It measures the distance between the satellites using microwaves (blue) and a laser interferometer (red).

Because of their expertise, @mpi_grav researchers are involved in the design of the laser interferometer for this and similar future missions.

@NewScience101
So would love to see a spacecraft similar to the twin GRACE-FO spacecraft that are mapping groundwater on Earth.

A similar mission for mapping potential subsurface water on Mars in detail, who knows maybe there are still aquifiers deep down with secrets from a long distant wet past.
