Wow a radical change in Perseverance's viewpoint wrt to the Pico Turquino hills has occured. The robot changed direction by 90° to offer us some new vistas of these hills with the crater floor now in the background!

1. A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colours reflecting different types of star. Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black.

this outcrop with a rather monstrous shape can also be found here, overlooking the delta

1. A light ochre toned photography of a Martian landscape dominated by a dusty atmosphere. In the lower right hand corner, occupying a tiny section of the field of view, an isolated rocky outcrop overlooks a vast expanse of sandy hills.

The look of this outcrop. Wild!
Captured 24 hours ago by Perseverance on the slopes of the crater rim.

The k’niPatn k’l⌣ stk’masqt outrigger (KKO) telescope.
The site is on the traditional territory of the #Similamix People in #BritishColumbia. The Upper #Similkameen #Indian Band offered the name, which means “a listening device for outer space”.

  CHIME/FRB Outriggers: KKO Station System and Commissioning Results
  
  Localizing fast radio bursts (FRBs) to their host galaxies is an essential step to better understanding their origins and using them as cosmic probes. The CHIME/FRB Outrigger program aims to add VLBI-localization capabilities to CHIME, such that FRBs may be localized to tens of milliarcsecond precision at the time of their discovery, more than sufficient for host galaxy identification. The first-built outrigger telescope is KKO, located 66 kilometers west of CHIME. Cross-correlating KKO with CHIME can achieve arcsecond-scale localization in right ascension while avoiding the worst effects of the ionosphere. This paper presents measurements of KKO's performance throughout its commissioning phase, as well as a summary of its design and function. We demonstrate KKO's capabilities as a standalone instrument by producing full-sky images, mapping the angular and frequency structure of the primary beam, and measuring feed positions. To demonstrate the localization capabilities of the CHIME -- KKO baseline, we collected five separate observations each for a set of twenty bright pulsars, and aimed to measure their positions to within 5~arcseconds. All of these pulses were successfully localized to within this specification. The next two outriggers are expected to be commissioned in 2024, and will enable subarcsecond localizations for approximately hundreds of FRBs each year.
