The rocket rose from Vandenberg Air Force Base in California at 12:47 p.m. PT after a problem-free countdown.<\/p>\n<p>SpaceX, which is transitioning to a new generation of its workhorse Falcon 9, made no plans to recover the first-stage booster after today\u2019s launch. However, it sent a net-equipped ship out into the Pacific to try making a \u201ccatcher\u2019s mitt\u201d recovery of hardware from the rocket\u2019s nose cone, or fairing.<\/p>\n<p>Launch commentator John Insprucker said the recovery ship, nicknamed Mr. Steven, \u201ccame very close\u201d to recovering fairing hardware, \u201cbut not quite.\u201d<\/p>\n<p>The payloads for this launch support government-funded science as well as privately funded commerce.<\/p>\n<h4>GRACE-FO: Tracking gravity and water<\/h4>\n<p><iframe title=\"Tracking Water from Space:  The GRACE-FO Mission\" src=\"https:\/\/www.youtube.com\/embed\/s93i7m82h54?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p>Two satellites for the Gravity Recovery and Climate Experiment Follow-On mission, or GRACE-FO, were deployed about 11 minutes after launch. The GRACE-FO is jointly supported by NASA and the German Research Center for Geosciences, and as the mission\u2019s name suggests, it follows up on the 15-year GRACE mission to track gravitational shifts in Earth\u2019s mass distribution.<\/p>\n<p>Gravity readings from GRACE have shown how water is being transported around the globe, primarily due to changes in climate and weather patterns. Just last week, scientists took advantage of GRACE data to publish a study suggesting that wet regions in the high latitudes and the tropics are getting wetter, while dry regions in mid-latitudes are getting drier.<\/p>\n<p>\u201cThe pattern of wet-getting-wetter, dry-getting-drier during the rest of the 21st century is predicted by the Intergovernmental Panel on Climate Change models, but we\u2019ll need a much longer data set to be able to definitively say whether climate change is responsible for the emergence of any similar pattern in the GRACE data,\u201d study co-author Jay Famiglietti of NASA\u2019s Jet Propulsion Laboratory said in a news release.<\/p>\n<p>The original GRACE mission ended last October. GRACE-FO is expected to take the handoff.<\/p>\n<h4>Iridium NEXT: The upgrade continues<\/h4>\n<p><iframe title=\"Iridium NEXT showcased during Satellite 2017 exhibition (Washington DC)\" src=\"https:\/\/www.youtube.com\/embed\/RcK5XJDbDEA?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen=\"\" data-ratio=\"0.5625\" data-width=\"800\" data-height=\"450\" style=\"display: block; margin: 0px; width: 800px; height: 450px;\"><\/iframe><\/p>\n<p>A little more than an hour after launch, five satellites were added to the Iridium NEXT telecommunications constellation. SpaceX had already put 50 of the satellites into low Earth orbit for Iridium. Today\u2019s deployment gets Iridium closer to its full strength of 66 operational satellites and nine on-orbit spares.<\/p>\n<p>Iridium NEXT has been called one of the biggest tech upgrades in history. The $3 billion satellite constellation will replace Iridium\u2019s existing network and open the way for enhanced data services.<\/p>\n<p>Iridium\u2019s Certus platform provides broadband access for specialized applications ranging from maritime emergency communications, to in-flight entertainment and high-speed internet access on airplanes, to high-quality satellite voice calls.<\/p>\n<p>During a Kratos podcast interview, Iridium CEO Matt Desch said the Internet of Things is the fastest-growing application for satellite communications.<\/p>\n<p>\u201cA lot of people think of Iridium as a satellite phone, but in fact, more than half of our subscribers are really connecting devices to machines, to things, vehicles and whatnot,\u201d he said. \u201cIt\u2019s the perfect thing to do that.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SpaceX\u2019s Falcon 9 rocket lifts off from California\u2019s Vandenberg Air Force Base.
