Two possibilities exist: Either we are alone in the Universe or we are not.
Both are equally terrifying.

Galileo signal updated for internet-of-things use

ESO Top News - Fri, 06/19/2026 - 9:55am

In April, Galileo marked a step forward with the deployment of a new signal component, known as E5a Quasi Pilot, on 12 satellites of Europe’s satellite navigation constellation. This upgrade makes Galileo signals easier to access, particularly on emerging mass-market, low-power devices used for Internet of Things and smart city applications.

Curiosity Blog, Sols 4920-4926: Surveying the Bands

Curiosity Blog, Sols 4920-4926: Surveying the Bands NASA’s Mars rover Curiosity acquired this image of small butte, “Miraflores,” using its Mast Camera (Mastcam) on June 11, 2026 — Sol 4922, or Martian day 4,922 of the Mars Science Laboratory mission — at 09:12:13 UTC. NASA/JPL-Caltech/MSSS

Written by William Farrand, Senior Research Scientist, Space Science Institute

Earth planning date: Friday, June 12, 2026

Rather than going from stage to stage at a music festival to hear different bands playing different varieties of music, Curiosity has been ascending up Mount Sharp through physical bands of exposed rocks with textural and tonal differences.

Planning for sols 4920 and 4921 were done with the rover in the middle of a unit with a rougher texture and dark-toned bedrock. With the rougher-textured bedrock, brushing wasn’t possible, but APXS chemistry and MAHLI micro-imaging were planned on “as is” bedrock targets “Salto La Cascada” and “Puerto de Rosas.” ChemCam was targeted to perform LIBS spectroscopy on a bedrock target “Kishuara” and a small, layered float rock “La Rosita.” ChemCam’s Remote Micro-Imager (RMI) collected views of the “Mishe Mokwa” butte and another looking at dunes with tonal differences. Mastcam mosaics were collected on the “Valle Grande” channel, “Kimsa Chata” butte, nearby troughs, and the aircraft carrier shaped rock “El Matir.”

Another drive brought Curiosity closer to the upper border of the dark-toned band. Again, brushing of the rocks was not possible, but APXS and MAHLI were collected on dark-toned bedrock targets “Santa Gracia” and “Laguna San Rafael” with ChemCam LIBS also targeting the bedrock. Mastcam mosaics were collected of a layered rock and nearby troughs and a mosaic of the nearby smaller butte, “Miraflores” which displays an interesting layered structure with ragged dark-toned rocks on one side and a stack of dust piled on top (see accompanying image). Other activities included a long-distance RMI mosaic of a bright unit on “Mishe Mokwa”, and Navcam dust-devil surveys in both sols.

Communicating between Earth and Mars has come to seem routine, but at times can still be a challenging endeavor and this was demonstrated to the team on Friday when we did not get a timely downlink of data for the drive planned for Sol 4923. Without these images another drive, in situ examinations, or targeted remote sensing could not be planned. However, there are always interesting things to be done on Mars and the three-sol plan (4924 to 4926) included a 360-degree Mastcam mosaic, the automatic AEGIS targeting of LIBS measurements on each sol, a Navcam dust-devil survey, APXS atmospheric measurements, as well as several other environmental activities.

On Monday, the delayed downlink will be used to plan the first investigation of the next band of surface materials, this one being smooth-textured and light-toned, as well as another drive to continue the surveying of the bands.
