SpaceX Falcon Heavy launch 'targeted' for Tuesday

SpaceX Falcon Heavy launch 'targeted' for Tuesday SpaceX’s Falcon Heavy rocket launch has been “targeted” for Tuesday from Kennedy Space Center’s Launch Pad 39A. The first commercial launch of the Falcon Heavy, the world’s most powerful rocket, is expected to draw 100,000 or more spectators to the Space Coast. 

The first launch is by SpaceX with the launch of a Falcon 9 Block 5 rocket. This Starlink mission is scheduled to occur on Wed May 15th 2019 10:30 PM EDT from Cape Canaveral, FL, USA. The status of the Starlink mission launch is Green with an 70% chance for favorable weather conditions.

SpaceX readied a previously-flown Falcon 9 rocket for launch Wednesday evening carrying 60 Starlink internet relay satellites. The satellites will help pave the way toward a planned constellation of nearly 12,000 needed to provide space-based internet connectivity around the world.

Stacked inside the rocket's 17-foot-wide nose fairing, the satellites were scheduled for launch from pad 40 at the Cape Canaveral Air Force Station at 10:30 p.m. EDT. SpaceX planned to attempt recovery of the rocket's twice-flown first stage with landing on an off-shore droneship.

First launch under SpaceX 's 2015 certification for national security space missions, which allowed SpaceX to contract launch services for classified payloads,[171] and thus breaking the monopoly ULA held on classified launches since 2006.[172] For the first time, SpaceX offered continuous livestream

The flight plan called for satellite deployment to begin about an hour after launch. The 60-satellite 30,000-pound payload is the heaviest launched to date by a Falcon 9 rocket.

"This mission will push the operational capabilities of the satellites to the limit," the company said in its mission press kit. "SpaceX expects to encounter issues along the way, but our learnings here are key to developing an affordable and reliable broadband service in the future."

SpaceX founder and chief designer Elon Musk was more blunt in n earlier tweet, attempting to lower expectations somewhat by saying "much will likely go wrong" on the initial mission. He also cautioned that six launches of 60 satellites each would be needed for even "minor" internet coverage on a global scale.

SpaceX now targeting May 1 to launch its 17th resupply mission to the ISS

SpaceX now targeting May 1 to launch its 17th resupply mission to the ISS SpaceX will be carrying crew supplies and more than 3,720 pounds of science to the ISS.

An unusual SpaceX launch will carry several startups' satellites, some of Now a SpaceX rocket is poised to launch a raft of internet satellites from a host of startups—but this time, the target audience is machines. Five of the six start -ups are launching just one satellite on SSO-A, with only Swarm

As of December 2017, SpaceX uses three leased orbital launch sites: Launch Complex 39A of the Kennedy Space Center, Space Launch Complex 40 at Cape Canaveral Air Force Station, both in Florida, and Space Launch Complex 4E of the Vandenberg Air Force Base in California.

The complete constellation, which reportedly will cost in the neighborhood of $10 billion, will be made up of nearly 12,000 Starlink satellites, up to 4,400 of them using Ku- and Ka-band radios with the rest using so-called V-band frequencies. The satellites will be deployed at three orbital altitudes — 210, 342 and 745 miles — in multiple planes to provide global high-throughput coverage.

To improve the flow of data through the system, the 500-pound satellites will be able to hand off internet connections to other Starlink spacecraft as needed without going through ground stations. The initial 60 satellites, however, do not feature such "cross-link" capability, which presumably will result in slower data throughput.

But fully operational follow-ons will "connect end users with low-latency, high-bandwidth broadband services by providing continual coverage around the world using a network of thousands of satellites in low Earth orbit," SpaceX said in its press kit.

SpaceX postpones Starlink satellite launch again, for 'about a week'

"To manufacture and launch a constellation of such scale, SpaceX is using the same rapid iteration in design approach that led to the successes of Falcon 1, Falcon 9 (rocket), Falcon Heavy, and Dragon. As such, Starlink's simplified design is significantly more scalable and capable than its first experimental iteration."

Once the constellation is operational, low-cost terminals, or receivers, will allow customers to tap into the truly worldwide web.

SpaceX launched two Starlink demonstration satellites as secondary payloads on a Falcon 9 in 2018.

"This next batch of satellites will really be a demonstration set for us to see the deployment scheme and start pulling our network together," Gwynne Shotwell, SpaceX president and chief operating officer, said earlier this month. "We start launching satellites for actual services later this year."

She added that two to six more Starlink flights may be launched by the end of the year, "but it largely depends on how we do on this first batch."

As wild as it sounds, the race is on to build a functioning space internet — and SpaceX is taking its biggest step yet with the launch of 60 (!) satellites tomorrow that will form the first wave of its Starlink constellation. It’s a hugely important and incredibly complex launch for the company — and should be

SpaceX is one of several companies, including Amazon, OneWeb and others, that are planning space-based internet services using vast constellations of satellites. The sheer number of satellites potentially bound for low-Earth orbit has raised questions about traffic management, collision avoidance how they will be removed from orbit at the end of their planned lifetimes.

SpaceX says its spacecraft are equipped with sophisticated systems allowing them to autonomously track nearby spacecraft and avoid collisions using Hall-effect ion thrusters for maneuvering and to push them back into the atmosphere at end of their missions.

In addition, "95 percent of all components of this design will quickly burn in Earth's atmosphere at the end of each satellite's lifecycle — exceeding all current safety standards — with future iterative designs moving to complete disintegration."

Wednesday's planned flight marked the sixth SpaceX mission so far this year, its fifth from Florida. Next up on the Falcon 9 schedule is launch of the Radar Constellation Mission for the Canadian Space Agency. Liftoff from Vandenberg Air Force Base, Calif., is targeted for June 11.

SpaceX plans to launch its third three-core Falcon Heavy rocket from the Kennedy Space Center in Florida around June 22 to boost a group of military payloads and experiments into orbit.

SpaceX is still in control of all but three of its internet satellites.
How are SpaceX's Starlink internet satellites faring roughly a month after launch? Quite well, if you ask SpaceX. The company reported that it's in contact with 57 of the 60 initial broadband satellites. Although it's not certain what happened to those three faulty satellites, they'll eventually fall to Earth as gravity drags them down. SpaceX also intends to deorbit two of the functioning satellites in order to test the process. It's still early days for Starlink, but it suggests that you won't see a host of dead satellites clogging up Earth's orbit. The concern is more one of scale.
