🚨 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.

🚨 Neues Header-Bild 🖼️
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.

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.

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.

"Die Verfügbarkeit von Wasserressourcen auf der Erde ist für unsere Gesellschaft von grosser Bedeutung. Diese Grösse zu messen ist, wie man sich vorstellen kann, nicht einfach. Dank der ständigen Weiterentwicklung von Satelliten ist es jedoch seit einigen Jahren möglich, die weltweiten Wasserressourcen aus dem Weltraum zu bestimmen."

And to put things into a longer term perspective here is the #GRACE + #GRACEFO satellite record showing the last 20 years of #gravimetry data.
@greenlandicesheet has lost #ice basically every single year..
This is also shown on the #PolarPortal

Hi 👋 this is my #Introduction
Glaciologist and geodesist living in #Seattle. Scientist at the #UW Applied Physics Lab and affiliate at the #eScience Institute. Formerly a postdoc at #NASA Goddard Space Flight Center. Using #ICESat2 and #GRACEFO to look at our Earth's #polar regions. Squinter of #maps. Glorified #cat bed.
How are we studying Earth's frozen regions? With 2 new missions & technologies! @NASA_ICE scientists will use data from #GRACEFO, which launched in May, and #ICESat2, which is launching Sept. 15 to better understand how frozen water affects our planet: https://science.nasa.gov/science-news/news-articles/cool-ways-of-studying-the-cryosphere?utm_source=TWITTER&utm_medium=NASA&utm_campaign=NASASocial&linkId=56864412 https://twitter.com/NASA/status/1040632016746758146/video/1 source: https://twitter.com/nasa/status/1040632016746758146
