    Hooray for Nasa! Nice to see everybody's efforts there were a success in the end.

    I delayed some shopping to watch the landing of InSight, and I was not disappointed. I followed it as it descended and landed. I especially liked that first picture, despite all the dust on it.

    InSight traveled with two Mars Cube One (JPL | Cubesat | MarCO) mini-spacecraft. This was their first flight, and there were two of them to be redundant, in case one of them fails. Both of them performed well, relaying the lander's broadcasts as it landed.

    CubeSat -- their basic size is 10 cm cubed, and the two MarCO ones were 1*2*3 ones.

    Some more pictures: Farewell to Mars | NASA from one of the MarCO craft, and InSight Is Catching Rays on Mars | NASA from InSight, relayed by the Mars Odyssey orbiter.

    I love this shit. So happy it landed. Now looking forward to some interplanetary intercourse when it penetrates deep into the crust.

    It's impending arrival seemed to have put Curiosity in a panic.

    And it further looks like their interaction did not go well.

    News | NASA's InSight Takes Its First Selfie -- a mosaic of 11 pictures.
    Mission team members have also received their first complete look at InSight's "workspace" - the approximately 14-by-7-foot (4-by-2-meter) crescent of terrain directly in front of the spacecraft. This image is also a mosaic composed of 52 individual photos.

    In the coming weeks, scientists and engineers will go through the painstaking process of deciding where in this workspace the spacecraft's instruments should be placed. They will then command InSight's robotic arm to carefully set the seismometer (called the Seismic Experiment for Interior Structure, or SEIS) and heat-flow probe (known as the Heat Flow and Physical Properties Package, or HP3) in the chosen locations. Both work best on level ground, and engineers want to avoid setting them on rocks larger than about a half-inch (1.3 cm).

    "The near-absence of rocks, hills and holes means it'll be extremely safe for our instruments," said InSight's Principal Investigator Bruce Banerdt of NASA's Jet Propulsion Laboratory in Pasadena, California. "This might seem like a pretty plain piece of ground if it weren't on Mars, but we're glad to see that."

    InSight update, sols 1-24: Operations begin, first instrument deployed | The Planetary Society -- a "sol" is a local solar day, a Martian solar day here.
    According to a post-deployment update posted to the JPL website, the seismometer has been placed about as far away from the lander as the arm can reach, 1.636 meters away. The next step in the long process of setting up InSight’s experiments is to level the seismometer; its placement spot has a very gentle slope of 2-3 degrees. They may (or may not) also nudge the tether ribbon slightly to minimize the noise it contributes to seismometer measurements (more on that below). After that, they’ll place a lid over the seismometer to shield it from wind, daytime heat, and nighttime cold. They expect to have the heat probe placed on the ground, about 1.2 meters to the left of the seismometer, by late January.
