EDIT: pokazali ich platformę "Photon". Ostatni Electron wyniósł prototyp na orbitę i wygląda, że działa:) Proton to właściwie mały pojazd kosmiczny pod którego można podczepić satelitę i użyć go do zmiany orbity. Za jego pomocą będą mogli wysyłać małe ładunki na Księżyc i dalej. Pomysł jest taki żeby dostarczyć jedną sprawdzoną platformę napędową zespołom budującym satelity aby Ci się zajęli głównym ładunkiem
Zatem górny stopień RN został satelitą technologicznym o nazwie First Light, który ma funkcjonować 5-6 lat.
Czyli nie jeden, a dwa ładunki zostały usatelitarnione podczas tego startu.

We just made in-space transportation even easier. After deploying 10 sats to perfect orbits for our customers on the #InFocus mission, the Kick Stage had one more trick up its sleeve. For the first time, we demonstrated a plane change maneuver.

(...) Rocket Lab nicknamed the mission “In Focus” in honor of the 10 Earth observation satellites on-board the Electron launcher. The California-based company delayed the launch from Oct. 21 to evaluate a concern with an oxygen sensor.

“Congratulations to Planet on the addition of their latest SuperDoves to their constellation and to the team at Canon Electronics on the deployment of their latest tech demonstration satellite,” said Peter Beck, Rocket Lab’s founder and CEO. “Electron has once again delivered a smooth ride to orbit and precise deployment for our individual rideshare customers.

The mission Wednesday marked Rocket Lab’s 15th launch of an Electron booster, and the company’s fifth mission of 2020.

“Continuing to launch in the face of global disruption and adversity, while at the same time becoming the second-most frequently flown U.S. launch vehicle this year, is the latest display of our dedication in providing ongoing, easy access to space for our customers,” Beck said.

The largest spacecraft on Wednesday’s mission was CE-SAT-2B, an Earth observation satellite for Canon Electronics of Japan.

The 78-pound (35.5-kilogram) spacecraft is Canon’s third microsatellite to launch, following an experimental Earth-imaging station that launched in 2017 on an Indian PSLV rocket.

A follow-on satellite named CE-SAT 1B launched in July on a previous Rocket Lab mission, but it was destroyed when the Electron rocket failed before reaching orbit.

According to Canon, CE-SAT-2B carries three types of cameras to be demonstrated in orbit.

“With the newly developed super high sensitivity camera, CE-SAT-2B is capable of observing the Earth during night time,” Canon said in a press release. “The satellite is equipped with three types of cameras including Canon’s mirrorless camera and compact digital camera.

“CE-SAT-2B will go through a two-year demonstration experiment for forthcoming production of cassegrain reflectors as series,” Canon said.

Spaceflight, a Seattle-based launch broker, arranged for the launch of CE-SAT-2B with Rocket Lab.

Nine SuperDove Earth-imaging satellites — each about the size of a large shoebox — ejected from Maxwell deployers on the Electron rocket’s kick stage. The SuperDove payloads, built and owned by Planet, will replace five similar satellites — collectively known as “Flock 4e”– that were also lost on Rocket Lab’s failed mission in July.

“Emerging from the unfortunate launch accident of Flock 4e on Electron in July, this next launch speaks to both Planet and Rocket Lab’s resilience and agility to get back on the pad so quickly,” Planet wrote in a blog post on its website. “These SuperDoves will be deployed into an approximate 500 km (310-mile-high) morning-crossing sun synchronous orbit (SSO), joining the rest of the flock already providing unprecedented medium-resolution global coverage and revisit.”

"Usatelitarnione"... Piękne słowo :) A co byś powiedział na "satelizowane"?

A tak z innej beczki - w następnym locie (NET 16 listopada) firma chce osadzić na wodzie pierwszy stopień i go wyłowić. To test przed odzyskiwaniem go podczas opadania na spadochronie.

Z tym czarnym kolorem to chyba przesadzają. Żeby coś wyraziście zobaczyć, należy grafikę bardzo powiększyć i ma się wtedy tylko fragmentaryczny widok.
Może to dlatego, że z 12 planowanych startów w 2020 doszło do 6, w tym jeden był nieudany  ;)

odzyskany stopień już z powrotem w fabryce.

I wreszcie mamy drugą firmę, która z sukcesem odzyskała pierwszy stopień rakiety orbitalnej.

Rocket Lab recovers booster after launch with 30 small satellites
November 20, 2020 Stephen Clark

(...) Beck said the company is taking an incremental approach to proving out its ability to recover and reuse Electron rocket boosters. Engineers want to see how well the booster survives re-entry, and it’s likely Rocket Lab will try several water splashdowns before attempting a mid-air recovery for the first time.

“If we’ve got a smoldering stump, then there’s really not much point in catching a smoldering stump with a helicopter,” Beck said earlier this month. (...)

“We’ve seen the cost of dedicated small launch come from anywhere from $50 million to $30 million for a Pegasus or a Minotaur (rocket) down to $7 million for a Rocket Lab vehicle,” Beck said.

If Rocket Lab is successful with reusing its boosters, “I think we’ll see a dramatic change in pricing again,” Beck said. (...)

Two of the spacecraft on the Electron launch were built by Millennium Space Systems, a subsidiary of Boeing, for a mission named DragRacer to test a drag-inducing device that could help small satellites in low Earth orbit naturally decay, or re-enter the atmosphere.

One satellite — named Alchemy — will extend a 230-foot-long (70-meter) electrically conductive tether, a device designed to increase the surface area of the spacecraft, allowing it to succumb to aerodynamic drag, re-enter the atmosphere, and burn up.

Both DragRacer spacecraft are identical, except that one carries the tether and the other — named Augury — does not.

According to preflight predictions, the satellite with the tether could re-enter the atmosphere within 45 days. The spacecraft without the tether — the control for the experiment — is expected to remain in orbit for around seven years, according to mission team members.

The device affixed to DragRacer’s Alchemy satellite is called a Terminator Tape. Developed by Tethers Unlimited, the tape measures just a few inches wide, but it can spool out to lengths of hundreds of feet.

The DragRacer experiment is a purely commercial experiment to quantify the effectiveness of the Terminator Tape technology, which Millennium and Tethers Unlimited say is a more reliable, lower cost, and less complex alternative to other deorbit methods, such as drag sails or propulsive thrusters.

“This scientific method experiment will demonstrate Millennium’s ability to field and fly a low-cost and straightforward orbital debris mitigation solution that doesn’t require added mass, volume, cost and complexity of propulsion system to deorbit a satellite in low Earth orbit,” said Stan Dubyn, founder and CEO of Millennium Space Systems, in a press release.

The two DragRacer satellites have a combined weight of around 55 pounds, or 25 kilograms, according to TriSept Corp., a partner on the DragRacer mission overseeing the integration of the satellites on the Rocket Lab launcher.

Ground-based radars will track the changing orbits of both DragRacer spacecraft to measure how they decay differently.

“The space community understands tether systems can expedite re-entry, but this is our first opportunity to truly quantify performance directly and more effectively calibrate models developed over the last 50 years,” said Robert Hoyt, founder and CEO of Tethers Unlimited. “Predictions suggest the tethered spacecraft will deorbit in approximately 45 days, while the untethered spacecraft remains in orbit for approximately 7 to 9 years.”

Tethers Unlimited’s Terminator Tape technology has flown before. The company says the tether module — which attaches on the exterior of a host spacecraft — weighs about 2 pounds and is about the size of a notebook, and is suitable for a range of satellite sizes.

The Prox-1 microsatellite developed by students at Georgia Tech deployed 230-foot-long Terminator Tape last year. Tethers Unlimited said tracking of the spacecraft showed its orbit decaying 24 times faster after extending the tether.

Flying two identical satellites on the DragRacer mission will allow engineers to better characterize the performance of the tether technology.

“The mission is completely about the demonstration,” said Jason Armstrong, director of TriSept’s launch and integration services, in an interview last year with Spaceflight Now. “So immediately upon separation from the launch vehicle, the two halves of the spacecraft will come apart from each other, and then we can deploy the tether on one half of the spacecraft and get immediate results.”

Armstrong said the benefit of the Terminator Tape over other deorbit solutions is its smaller volume and mass.

“It’s much less complex as far as the capabilities you need to have for actuating and deploying the system,” Armstrong said. “On-board, all we need to have is a small timer with a little battery mechanism. That’s very attractive (to satellite operators) because you’re not introducing risk or any high complexity systems that have to talk to your flight computer.” (...)
