      480. Alas, InSight's mole got stuck only 30 cm down in its first attempt to burrow. 😢 Scientists & engineers worked to figure out why: Did it hit a boulder? An empty void in the dirt? Was the dirt just weird in an unexpected way? (This is what exploration is all about!)pic.twitter.com/sSYOGLbGGS

      481. The lander engineers tried using InSight's arm to help get the mole going downward again. It seemed to be working at first...until Mars partially burped the probe back out. Like a cat at the vet, I guess Mars didn't want its temperature taken.pic.twitter.com/K2EaurF9qU

      482. Strategizing on other ways to get the mole working again are still underway, but this process has taught us a lot! @NASA has a good Q&A about the probe here:https://mars.nasa.gov/news/8444/common-questions-about-insights-mole/ …

      483. Another instrument aboard InSight is RISE—the Rotation & Interior Structure Experiment. It consists of a set of antennae on either side of the lander, precisely tracking its location each day. Why would we need this if it's a lander that's not going anywhere?

      484. By precisely measuring where InSight is, RISE tracks how much Mars "wobbles" in its orbit around the Sun. This in turn helps reveal info on the interior structure of Mars—the size of its core, and whether it's liquid (like ours) or solid. (Image: IPGP/David Ducros)pic.twitter.com/Q35KbxQANy

      485. Two CubeSats hitched a ride to Mars with InSight, called MarCO. We talked about these earlier in this thread (see #299), but that was pre-launch. They ended up being successful in their mission acting as comms relays during InSight's landing—the 1st interplanetary CubeSats!pic.twitter.com/ZfPC82iAnw

      487. The MarCO CubeSats were equipped with tiny, commercial off-the-shelf cameras from @gumstix. They weren't part of the main goals of the mission, but returned some cool retro-looking images & showed these inexpensive cams could work in deep space!pic.twitter.com/pfyAtp4PHV

      488. After flying past Mars during InSight's landing as planned, the MarCO CubeSats continued to operate for a little over a month before contact was lost (which was expected). They're now orbiting the Sun silently, but could wake up this summer if they get enough solar juice.pic.twitter.com/B8N0pskYck

      490. InSight (+ MarCO) was NASA's first interplanetary mission to launch from Vandenberg in California, rather than Cape Canaveral. @DJSnM has a great @KSpaceAcademy-filled video on why this was the case:https://www.youtube.com/watch?v=U5FIhHm47Cc …

          492. Since it's made to study Mars' atmosphere, MAVEN is unique in that it doesn't have any specific surface-imaging cameras like every other satellite at Mars carries. Instead it has a UV imager, which helps water-ice and dust clouds stand out: https://mars.nasa.gov/news/nasas-maven-mission-gives-unprecedented-ultraviolet-view-of-mars/ …pic.twitter.com/EDAAllytAB

          493. MAVEN launched to Mars on November 18, 2013—which I attended as part of an amazing #NASASocial and reporting for The Planetary Society. This was MAVEN on the pad the night before leaving Earth.pic.twitter.com/oHVIpdOkDg

          495. MAVEN was able to measure the rate at which Mars' atmosphere is being stripped away by the solar wind: 100 grams of gas every second! This is because it no longer has a magnetic field to protect it, unlike Earth.https://www.youtube.com/watch?v=gX5JCYBZpcg&feature=emb_title …

          496. MAVEN's measurements have supported the hypothesis (based on models + observations of features on the surface like ancient channels) that Mars' atmosphere was once much thicker and more Earth-like in its past, but has slowly been stripped away by the solar wind.pic.twitter.com/keab2OdR73

          498. Comet Siding Spring flew past Mars back in 2014, and MAVEN was able to capture the effects on Mars' atmosphere. The comet left dust behind in its wake, which MAVEN was able to detect—might've caused martian meteor showers! (These are pics of the comet from Hubble.)pic.twitter.com/r01BulibvY

          499. Comet Siding Spring's close pass by Mars—less than 1/2 the distance between Earth & Moon—left behind a temporary ion layer in Mars' atmosphere from its dust! The two radar instruments in orbit, MARSIS and SHARAD, were both able to detect these effects.pic.twitter.com/bUDnSCzJTQ
