Today at 4:25pm EST, SpaceX's Falcon 9 rocket took to the skies carrying the GovSat-1 satellite. The Falcon 9 rocket launched from Cape Canaveral, Florida off of Space Launch Complex 40 (SLC-40). The first stage of the Falcon 9 included recovery hardware, but would not be attempting a recovery. They would follow the regular landing procedures without landing on the droneship and it was planned to fall over into the water and explode due to the highly pressurized tanks rupturing. The first stage landed in the water and fell over - without exploding. Elon Musk tweeted, "...amazingly it has survived. We will try to tow it back to shore" and possibly have parts salvaged from it, but not official.

The GovSat-1 satellite is the first of its kind and has been manufactured by Orbital ATK and is partnered with SES. The satellite is designed to address governmental and institutional security user needs and enables secure communication links between tactical operations for maritime missions. It is equipped with anti-jamming features and has encrypted telemetry connections. It'll be positioned over the equator supporting communications within Europe, the middle east, and Africa, as well as over the Atlantic and Indian Oceans.

Later this afternoon at 4:25pm EST (21:25UTC), SpaceX will launch the GovSat-1 satellite with their Falcon 9 rocket. The Falcon 9 will launch from Space Launch Complex 40 (SLC-40) to carry the satellite into a Geostationary Transfer Orbit (GTO). The first stage of this Falcon 9 previously supported the NROL-76 mission back in May 2017 and SpaceX will not attempt a recovery of this booster. Still equipped with recovery hardware, we can assume they will still attempt a soft landing in the ocean for additional data to study and improve landings in the future.

Today around 12:30pm EST, SpaceX's Falcon Heavy rocket ignited its 27 Merlin engines for the very first time as a complete launch vehicle. For the static fire, they followed normal launch procedures with the fueling of the 3 cores and the upper stage and then igniting the engines in a staggered pattern to reduce the torque forces on the octowebs. The rocket fired all the engines for around 7-11 seconds and generated quite a bit of steam as the huge plume grew away from the launch pad. Elon Musk confirmed a good static fire and said that Falcon Heavy would "launch in a week or so".

After many scrubs and a delay, Rocket lab launches their Electron rocket into the sky above the Mahia Peninsula in New Zealand. The carbon-composite launch vehicle ignited its 9 Rutherford engines and launched off the pad about 2 seconds after engine ignition. The rocket climbed through the atmosphere and the first stage cutoff and separated about 2.5 minutes after launch. The second stage carried the 3 satellites into Low Earth Orbit. Electron launched an Earth-imaging Dove satellite for Planet labs and two Lemur-2 satellites for Spire that allows gathering data for weather and ship tracking.

Atlas V launch scrubbed due to ground issue

Tonight's launch of the Atlas V carrying the SBIRS GEO-4 satellite has been scrubbed for the day due to a ground issue associated with the booster liquid oxygen system. The next launch attempt will occur tomorrow, January 19th, from SLC-41 at the Cape Canaveral Air Force Station. The weather forecast shows a 90% chance of favorable weather conditions. The Atlas V will lift off the launch pad at 7:48PM EST.

Tonight at 7:52pm EST, United Launch Alliance will be launching their Atlas V rocket in the 411 configuration. The Atlas V will be carrying the SBIRS GEO Flight 4 satellite for Lockheed Martin. The encapsulation of the payload occurred on Tuesday, January 9th at the Cape Canaveral Air Force Base in Florida. Prior to encapsulation, the satellite went under a lot of testing to ensure that the payload was ready to undergo the stresses during launch. The Atlas V trekked its way to Space Launch Complex 41 (SLC-41) yesterday with the SBIRS GEO-4 satellite mated to the upper centaur stage.

The Atlas V for this mission is in the 411 configuration, which means the rocket has a 4-meter payload fairing while using 1 Solid Rocket Booster (SRB) with one engine on the second stage. The reason for the single SRB is to get the payload up to its desired orbit while having fuel left over to de-orbit the upper stage after mission completion. The 2 RD-180 main engines used on the first stage use their large gimbal range to be able to compensate for the thrust from the SRB.

SBIRS GEO-4 is manufactured by Lockheed Martin and will join the three SBIRS GEO satellites that have been launched since 2011. These satellites will provide an early warning of missile launches that are headed for the US, including launched nuclear weapons. Two additional satellites have been ordered by Lockheed Martin and will be launched in the early 2020s. These SBIRS GEO satellites can also register emissions from wildfires, meteors, satellite reentries, and nuclear detonations.

Welcome home, Dragon! SpaceX's Dragon spacecraft returns to Earth after almost a month at the ISS

SpaceX's Dragon spacecraft reentered Earth's atmosphere carrying approximately 4,100 pounds of scientific research and hardware for NASA. Dragon successfully splashed down and was recovered in the Pacific Ocean by the SpaceX team a bit off the coast of California. Dragon will be brought back into port and will be transported to their HQ in Hawthrone, CA for unloading of the cargo and inspection of the spacecraft. This was the second time that this Dragon has been flown to space back.

Dragon launched on a flight-proven Falcon 9 rocket back on December 15th, 2017 from Space Launch Complex 40 by SpaceX. This mission was the first time that NASA had agreed to use a flight-proven Falcon 9 booster, which previously supported the CRS-11 mission back on June 3rd, 2017. The first stage conducted a "Return To Launch Site" (RTLS) recovery where it flipped around and fired its engines back toward Cape Canaveral where it landed softly at Landing Zone 1 (LZ-1). The Dragon spacecraft was also flight-proven and had previously launched the CRS-6 mission which launched April 14th, 2015.

The Dragon Spacecraft launched approximately a total of 4,861 pound of more than 250 science experiments and research investigations to the International Space Station (ISS). These experiments are going to be conducted during Expeditions 53, 54, and 55. This is the 13th of the 20 missions that SpaceX is contracted to send to the station under NASA's Commercial Resupply System (CRS). This contract was awarded to SpaceX to send resupply missions to the ISS through 2024 under the second CRS contract which was announced back in January of 2016.

The encapsulation of the SBIRS GEO-4 satellite was completed today at the Cape Canaveral Air Force Station in Florida. This is a significant milestone in its launch process. It marks the completion of the satellite's major testing milestones prior to launch. On January 10th, the satellite will make its way to SLC-41, where it will be mated with the Atlas V rocket and is currently scheduled to launch on January 18th at 7:52pm EST.

SBIRS GEO-4 is manufactured by Lockheed Martin and will join

The satellite that will be launched on the 18th will be carried by an Atlas V in the 411 configuration. This includes a single solid rocket booster and a four-meter-diameter fairing, the previous launches used an Atlas V without any SRBs. This change in the flight configuration will let the Centaur upper stage make a de-orbit burn and a controlled reentry to prevent adding more space debris into Earth orbit.

Falcon Heavy will be performing a static fire Wednesday

SpaceX's long awaited Falcon Heavy rocket emerged from the hangar at LC-39A once again and trekked to the pad ahead of a static fire. Pending a successful static fire, the launch is currently NET January 25th. The Falcon Heavy, in basic terms, is basically 2 Falcon 9 first stages mounted on the sides of a normal Falcon 9, but it's a lot more than just that.

 From an engineering standpoint, this is the most complex system that SpaceX has worked on to date. Their original plan was to have

fuel crossfeed from the side boosters into the core booster, but has been abandoned as of now because of the complexity. If this static fire is successful, we should see a launch "by the end of the month" as Elon stated in a tweet a few days ago. Inside the payload fairing is Elon Musk's original Tesla Roadster and the plan is to send the roadster to an orbit near Mars, while playing "Space Oddity".

Musk described the decision as "a red car for a red planet", as well as saying that for the first launch it would be a more exciting payload. Most rockets carry water ballasts or weights on their maiden flights, Musk described that for a payload as "boring" and nobody likes boring stuff. Many people are anticipating the launch of this amazing piece of engineering and the excitement is growing as the launch date begins to firm up. The first fully-stacked static fire of the rocket has a low chance of being successful the first time, but it's a possibility it goes flawless.

At 8:00pm EST, SpaceX's Falcon 9 rocket lifts off from Space Launch Complex 40 (SLC-40) from the Cape Canaveral Air Force Station for the first time this year. The Falcon 9 launched the 'Zuma' satellite into orbit around Earth. The intent of this government satellite is unknown as no information will be released about it. After the first and second stage separated, the second stage continued on toward orbit as the webcast coverage switched to only focus on the first stage after fairing separation, because of the classified nature of the satellite. The first stage flipped around and boosted back toward the coast and successfully landing at Landing Zone 1 making it the 17th consecutive landing for SpaceX and overall the 21st landing of the booster. Zuma was originally supposed to launch on November 16th, 2017, but was delayed due to a fairing issue that was discovered during fairing testing for another customer.

Now that Zuma launched, the next thing for SpaceX is a static fire and launch of their long awaited Falcon Heavy rocket. This three-core rocket consists of a redesigned first stage for the core booster and reused Falcon 9s that have been fitted to be side boosters. Over the last few weeks Falcon Heavy has been assembled in the hangar at LC-39a and has been raised vertical for pad fit checks. A static fire for the rocket will be conducted sometime this week with a launch scheduled for late this month.

After several delays because of maintenance and some fairing issues, "Zuma" is ready to launch. SpaceX had originally planned to launch Zuma from Historic LC-39A on November 16th being an issue showed up during testing of a fairing set for another customer. After Zuma would've launched, all focus would go toward Falcon Heavy and getting the launch pad ready for the launch, but since the long delay, the employees started work on getting Falcon Heavy ready for its launch this month. The classified satellite was un-mated from the fully stacked Falcon 9 and moved elsewhere for safe storage. The Falcon 9 that will be used to launch Zuma has been moved to SLC-40 to launch from there to make room for Falcon Heavy at LC-39A. The launch for Zuma is currently set for Thursday, January 4th with a two-hour launch window starting at 8:00pm EST. The Falcon 9 will lift off from SLC-40 carrying Zuma and will perform a landing back at SpaceX's Landing Zone 1 almost 8 minutes after liftoff. The webcast for the launch will go live on SpaceX's website about 15 minutes before liftoff.
