Smallsat Rideshare Program от SpaceX

[Zhilinsky Valerij]

Пожалуй, пора открывать тему по программе SpaceX по запуску малых спутников.
   
Для меня сигналом об этом стал вот этот твит:

SpaceX

More than 100 spacecraft have been signed up to fly on Falcon 9 since we launched the rideshare program. Small satellite operators can book their ride to orbit online → http://spacex.com/rideshare

Похоже, кончился миф о том, что спрос на космические запуски не эластичен.

Планируемые:
2) NET July - SAOCOM-1B, Smallsat Rideshare Mission 1 (SSO): Capella 2 (Sequoia), GNOMES-1 - Falcon 9 (L) - Canaveral SLC-40 - 23:21
3) October - Smallsat Rideshare Mission 9 (SSO) - Falcon 9 - Vandenberg SLC-4E / Canaveral SLC-40
4) December 16 - Smallsat Rideshare Mission 11 (SSO) : Vigoride, Delfi-PQ, EASAT, Grizu-263a, HADES, LibertyQube 1, Lemur-2 (x8), Outpost Demonstration 1, PlasmaBrake, Pycubed, RadCube, SpaceBEE (x12), Sattla, Tartan Artibeus, TRSI 2, Umbra-SAR 2001, VZLUsat 2, XR-1, LINCS cubesat (x2), ELaNa 35: PTD-1 + multiple satellelites - Falcon 9 - Vandenberg SLC-4E

SpaceX announced that more than 100 small spacecraft are contracted to launch on future Falcon 9 rideshare missions less than 10 months after the company's Smallsat Program opened its doors.

Critically, this milestone suggests that even before a single launch was completed, demand for SpaceX's unprecedentedly affordable smallsat launch services is so strong that the program is all but guaranteed to contribute outsized revenue. Thanks to the company's free-for-all, rapid-fire approach to rideshares on its massive Falcon 9 rocket, there could be monthly opportunities for unrelated small spacecraft to launch on Starlink missions – followed by one or two dedicated rideshares to a slightly different orbit – for the indefinite future.

After securing ~100 customers in a matter of months, SpaceX's Smallsat Program has proven that it's already a heavyweight to be reckoned with.

Per SpaceX's own online portal, where customers can legitimately purchase a smallsat launch contract in a matter of minutes, the potential revenue generated from >100 contracts could be even more than $100 million. For a number of reasons, however, $50-75 million is a much more reasonable – and still extremely impressive – ceiling. Equivalent to the cost of 7-10 launches of Rocket Lab's small Electron rocket, the ultimate price paid by any given SpaceX rideshare customer is at least several times – if not a magnitude – less.

The compromise: much like taking a bus instead of the cab, customers have to accept that they'll likely be dropped off – at best – in the general vicinity of their optimal destination. For some small satellites, that's likely a showstopper or major qualm. For many others, though, millions of dollars of launch cost savings could easily make up for the inconvenience. It's even possible that companies could choose to add more capable off-the-shelf propulsion offered by a ever-growing number NewSpace suppliers to their spacecraft, effectively allowing a smallsat to head from a given rideshare 'bus stop' to its preferred orbit.
 
Down the road, space tug startup Momentus Space has already signed several contracts with SpaceX to include its Vigoride and Vigoride Extended spacecraft on future Smallsat Program launches. With Vigoride and space tugs like it, smallsat owners could feasibly contract with Momentus to have their satellites delivered to a custom orbit after launching with SpaceX. It remains to be seen if the cost of a combination rideshare-spacetug launch contract can compete with a dedicated small launch vehicle like Electron, but early signs are extremely encouraging.

Scheduled to launch no earlier than December 2020, SpaceX's very first dedicated rideshare mission will include a Momentus Vigoride space tug that has already secured contracts worth more than $6 million for a portion of its 250 kg (~550 lb) payload capacity.

All things considered, given that the very first Smallsat Program rideshare was completed less than a week ago on June 13th, SpaceX is likely just getting started. Once the company has thoroughly proven the value of its smallsat launch offering with several launches and many happy customers, it's possible that SpaceX's first 100 contracts will pale in comparison to the demand it sees a year or two from now.

на мой взгляд полет СтарЛинка -8 и следующий , это совершенно  не тот РейдШере , о котором изначально (и довольно громко говорилось). Тот Рейд Шере это  полеты "по расписанию" 2-4 раза в год  в известный месяц  и орбиту (как и ездит маршрутка расписание и маршрут).
То что произошло в июне и может еще произойдет, это классический попутчик , которым балуются  все операторы пусковых услуг..

так что я все таки подождал бы когда полетит  (или объявят об обещанном полете)  по программе rideshare)

Я соглашусь с тем, что это не запуск носителя по программе rideshare, эти носители запускаются по программе запуска Старлинков, а спутники, запускавшиеся с ними, были классическими попутчиками. Но по программе rideshare доступен выбор для запуска на Старлинках (и даже, наверное, другие запуски).

Тем не менее, на перенесённом на 25 июня запуске Старлинков тоже есть "попутчики":

SPACEFLIGHT TO LAUNCH ITS FIRST RIDESHARE PAYLOADS ON A SPACEX STARLINK MISSION
By Jodi Sorensen
JUNE 17, 2020

For its fifth mission aboard a Falcon 9, the rideshare service provider readies two BlackSky microsatellites for launch on upcoming Starlink mission

SEATTLE – June 17, 2020 — Spaceflight Inc., the leading satellite rideshare and mission management provider, today announced it will launch two rideshare payloads aboard SpaceX's tenth Starlink mission, marking the first SpaceX Starlink mission that will be accompanied by Spaceflight rideshare payloads. The ability to launch rideshare payloads aboard SpaceX Starlink missions provides smallsat customers with a new, reliable and routine launch option. Spaceflight's mission, which it has dubbed SXRS-1 to signify its first rideshare with Starlink, will include two Earth-observation microsatellites for Spaceflight's customer BlackSky.



In addition to securing capacity aboard the vehicle, Spaceflight designed the adapters and harnessing, and executed the integration of the rideshare payloads. The mission is targeted to launch in the coming weeks from Launch Complex 39A at Kennedy Space Center in Florida.

"SpaceX has proved schedule consistency and launch reliability through its Starlink missions, even during this unprecedented time, and we are eager to offer it as a launch option to our customers," said Curt Blake, president and CEO of Spaceflight. "We seek to maximize capacity on every launch because any space available is an opportunity for our customers to complete their missions. We've executed many firsts with SpaceX, including SSO-A, the first dedicated rideshare mission on a U.S. vehicle as well as the first-ever rideshare mission to Geosynchronous Transfer Orbit with a lunar lander. We're looking forward to another first with SpaceX."

Spaceflight also announced today it inked an agreement with SpaceX to secure rideshare capacity on multiple launches. This agreement between the two companies secures Spaceflight capacity to launch manifest payloads on several SpaceX launches through the end of 2021, providing launch schedule assurance to smallsat customers needing frequent, reliable, and cost-effective launches to Sun-synchronous orbit.

Spaceflight works with a large portfolio of launch vehicles, including Falcon 9, Antares, Electron, Vega, and PSLV, to provide a variety of launch options to its customers. Spaceflight has launched more than 270 satellites across nearly 30 rideshare missions. In 2019, the company successfully executed nine missions, the most it's ever launched in one year, sending more than 50 payloads to space. This year, Spaceflight is scheduled to execute more than six missions.
