Sols 1123-1125: Drill hole and tailings

2 October 2015

The weekend plan includes lots of arm activities and science.  First, on Sol 1123, ChemCam and Mastcam will observe the drill hole and tailings, plus targets named "Frontier," "Floweree," "Bozeman," and "Billings."  Then the portion of the sample that has not been sieved will be… Read More

Sol 1121-1122: Successful Drill at Big Sky

30 September 2015

Success! Our drill at “Big Sky” went perfectly! On Sol 1121, the rover will transfer some of the powder from Big Sky to CheMin so that it can begin analyzing the mineralogy of the sample. Also on Sol 1121, ChemCam has an observation of the target “Minnekahta”. Mastcam will… Read More

Sol 1119-1120: "Go" for full drill at Big Sky!

28 September 2015

As you can see, our mini-drill over the weekend went well, so we are GO for drilling “Big Sky” on sol 1119! The hope is that this location will provide a good sample of the “typical” rock in the area to compare with some of the interesting alteration we’ve been seeing.… Read More

Sols 1116-1118: Small drill, Big Sky

25 September 2015

It’s time to drill again! After much deliberation, we have decided to try drilling the target “Big Sky” at our current location, in hopes of getting a good sample of relatively unaltered bedrock to compare with some of the altered rocks we have seen nearby. Sol 1116 is dedicated… Read More

Sols 1114-1115: Contact science on Big Sky

23 September 2015

The 14-meter Sol 1112 drive completed as planned, and the rover is in a good position for contact science.  There are flat areas in front of the rover that are suitable for drilling, so the Sol 1114 plan includes DRT brushing, MAHLI imaging, and APXS measurements of a target named… Read More

Sol 1112-1113: Rough Driving

21 September 2015

The drive on Sol 1111 stopped early after just over 15 meters because we were driving over rough terrain and part of the rover’s suspension exceeded the allowed amount of tilt (this is not a physical limit, just a threshold in the software that tells the rover to stop and check with Earth to… Read More
