SpaceX successfully lands its Falcon 9 rocket after launching military satellite

The company's fourth ground landing

by Loren Grush@lorengrush May 1, 2017, 7:26am EDT

This morning, SpaceX successfully landed its Falcon 9 rocket on solid ground again, after launching the vehicle from Cape Canaveral, Florida. The vehicle's first stage — the 14-story core of the rocket that contains the main engines — touched down at the company's landing pad called Landing Zone 1, located just off the coast of the Cape. It's the fourth time SpaceX has landed one of its rockets on land, and the 11th time the company has successfully recovered a rocket post-launch.

Today's rocket took off at 7:15AM ET, lofting a secret spy satellite dubbed NROL-76 for the National Reconnaissance Office. It's the first mission that SpaceX has done for the US military, after receiving certification to launch satellites for the Air Force in 2015. Since this was a national security launch, not much is known about the purpose of today's mission, or the satellite's intended orbit.
 
Additionally, the live broadcast of today's launch was a bit different than SpaceX's commercial missions. The livestream only showed viewers shots of the rocket's initial descent, and didn't reveal many views of the rocket as it ventured deeper into space. Instead, the audience was treated to multiple views of the Falcon 9 first stage as it made its descent back to Earth. In fact, there was a nearly continuous shot of the falling rocket taken from the ground — an angle of the landing we've never quite seen captured in the online broadcast before.


SpaceX

SpaceX used a brand new Falcon 9 for today's launch, but just last month the company finally demonstrated that it was capable of re-flying rockets that have flown to space before. The company launched a satellite for Luxembourg-based operator SES, using a Falcon 9 first stage that had launched and landed in April 2016. That first stage also landed after take off, though it touched down on one of SpaceX's floating drone ships in the Atlantic.

It's not clear when SpaceX will fly its next used Falcon 9, but it's possible we could see previously flown first stages being used for both commercial launches and military mission. An Air Force official indicated that flying on used Falcon 9s is certainly an option for the military. "I would be comfortable with flying with a reused booster," Gen. John "Jay" Raymond, commander of Air Force Space Command, said at the 33rd Space Symposium in Colorado Springs this month, according to Florida Today. "They've proven they can do it. It's going to get us to lower cost; it's going to get us to being able to get satellites in orbit. That's why they bring the boosters back. I think we'd be hard-pressed to say we're not going to do it. We would embrace that."

Eventually, SpaceX hopes to use its landed Falcon 9 rockets more frequently and drastically decrease turnaround time from the vehicle's landing to another mission. Last month, CEO Elon Musk said he's challenged the SpaceX team with getting a landed first stage ready for flight again in as little as 24 hours.

Крупный план первой ступени в свободном падении интересно смотрелся.

Маск опять молодец: организовать в реальном времени съемку первой ступени на всей траектории - очень нетривиальная задача.

И телеметрия 1-й ступени до момента посадки! Слава NRO!

У наших креатива хватило только на "Подними голову!" Ничего не поделаешь - отсутствие фантазии, конкуренции и малейшей увлеченности космонавтикой  .

[Старый]

Возврат ступени к месту пуска - значит спутник маааааленький.

[Дмитрий Ильин]

Пользуясь случаем, поздравляю всех россиян с праздником, днём весны и труда! Ждём "Ангару" и "Федерацию"! Этот запуск - хороший подарок любителям космонавтики от Илона Маска и SpaceX!


Дмитрию Олеговичу Рогозину особый космический респект!

 заместитель начальника штаба ВВС США по операциям генерал-лейтенант Джон (Джей) Реймонд сообщил журналистам о готовности Пентагона платить SpaceX за доставку на орбиту спутников военного назначения при помощи носителей Falcon 9 с повторно использованными ступенями.

Вот это успех !

Достижения есть. Будем наблюдать, сумеет ли SpaceX реализовать свою цель - удешевить запуски посредством возвращаемых ступеней и обтекателей. Начало проложено, удачи, Илон! Если цель будет достигнута, сбудутся мечты популяризаторов, фанатов и деятелей космонавтики!

SpaceX's Falcon 9 rocket is carrying a classified national security payload for the U.S. National Reconnaissance Office. This will be SpaceX's first launch for the NRO.

This launch marked the third launch to use the Autonomous Flight Safety System and the fourth successful landing of the Falcon 9 first stage booster on SpaceX's Landing Zone 1 at CCAFS. AFSS takes ground-based mission flight control personnel and equipment out of the control center and replaces it with on-board Positioning, Navigation and Timing sources and decision logic.  The benefits of AFSS include increased public safety, reduced reliance on range infrastructure, reduced range spacelift cost, increased schedule predictability and availability, operational flexibility, and launch site flexibility.

The Falcon 9 NROL-76 launch was the seventh major launch operation for the Eastern Range this year. Before any launch can blast off from the range, a dedicated team of military, government civilians and contractors from across the wing provide the mission assurance to ensure a safe and successful lift-off for range customers.

"Assured access to space is a team sport here on the Eastern Range."

"We continue to play a vital role in assuring access to space and this launch demonstrates our capability to keep up the pace as we move closer to our goal of 48 launches a year," said Brig. Gen. Wayne Monteith, 45th Space Wing commander.  "It takes less than a minute to get a rocket safely out of our atmosphere, but this launch was the culmination of many long hours and preparation though a series of rigorous rehearsals, readiness reviews and pre-operational checkouts.  This mission once again clearly demonstrates the successful collaboration we have with our mission partners at NRO and SpaceX as we continue to shape the future of America's space operations and showcase why the 45th Space Wing is the 'World's Premiere Gateway to Space.'"

REVISED #NROL76 Falcon 9 2nd stage d/l could be 2213.5/2251.5 or 2232.5/2272.5MHz. Payload guess 2249.5 or 2242.5MHz

First pass of #NROL76 over EU; possible detection of weak broadband radio signals from @spacex #Falcon9 2nd stage. Consistent with LEO orbit
