Rocket Lab’s Electron rocket is set to launch 13 CubeSats Saturday night (U.S. time) under contract to NASA from the company’s privately-owned spaceport in New Zealand, a pathfinder mission that could pave the way for more NASA satellites to hitch a ride on future Electron flights.

The nanosatellites cocooned inside the tip of the 55-foot-tall (17-meter) Electron launcher come from NASA’s Goddard Space Flight Center, Glenn Research Center and Langley Research Center, along with the U.S. Naval Academy and educational institutions in California, Florida, Idaho, Illinois, New Mexico and West Virginia. There are also CubeSats from the Aerospace Corp. based in Southern California, and the Defense Advanced Research Projects Agency — the research and development arm of the U.S. Defense Department.

The two-stage, all-black carbon composite launcher is set for liftoff in a four-hour window opening at 0400 GMT Sunday (11 p.m. EST Saturday) from Rocket Lab’s Launch Complex 1, located at Mahia Peninsula on the east coast of New Zealand’s North Island.

The launch window opens at 5 p.m. local time at the launch base in New Zealand, located around 240 miles (380 kilometers) southwest of Auckland, home of the company’s main control center and rocket assembly facility.

Officials delayed the mission from Wednesday night (U.S. time) to wait for improved weather conditions.

Rocket Lab has until Dec. 21 (New Zealand time) to send the fourth Electron flight — the Electron’s second operational mission — into orbit, a restriction based on aviation and maritime clearances around the launch site.

“It is an honor and privilege to launch NASA payloads on Electron, and to be the first small satellite launcher to fly under a NASA Venture Class Launch Services contract,” said Peter Beck, Rocket Lab founder and CEO, in a statement. “Reaching orbit twice already this year has made 2018 a banner year for Rocket Lab. Capping it off with our first launch for NASA is a tremendous way to celebrate the new era of improved access to orbit for small satellites.”

Since the Electron’s first test launch fell short of orbit in May 2017, Rocket Lab has accomplished two back-to-back successful missions this year — first with an orbital test flight in January, and then with the company’s first operational satellite launch Nov. 10 (U.S. time).

The Electron rocket is sized to haul small satellites into orbit, and it’s the first of a wave of new light-class commercial launchers in development to enter service.

Like its competitors, Rocket Lab says it can provide CubeSats and microsatellites a dedicated ride into orbit at a bargain price per launch. Smallsats have previously launched as secondary payloads, usually at the whim of the schedule and destination of the rocket’s main passenger, forcing smallsat owners to compromise on orbital parameters like inclination and altitude, which can affect the commercial utility to scientific output of a space mission.

Rocket Lab’s first launch pad is in New Zealand, but the company is building a second pad at the Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia. Rocket Lab is headquartered in Huntington Beach, California, where it builds engines and avionics for the Electron vehicle. The Auckland site is home to the company’s mission control center, tank production and Electron’s final assembly hall.

“It’s great because now we have the ability to have our own vehicle class that focuses on the small arena,” said Garrett Skrobot, a senior mission manager from NASA’s Launch Services Program at the Kennedy Space Center, which oversees the launch of the agency’s science missions. “To me, it’s opening the door to a lot of new adventures for the small payload class and community. It’s not just us. The other government agencies are also looking at this. The commercial market is looking at it.”

As space technology matures, miniaturized components allow fleets of smallsats to do missions that once required bigger spacecraft that are more expensive to build and launch. Companies such as Planet and Spire are using CubeSats for Earth-imaging, weather forecasting, and aircraft and ship tracking, and huge constellations of relatively small refrigerator-sized communications satellites are planned by SpaceX, OneWeb, Telesat and other firms.

“Look at how many Flocks (Earth-observing CubeSats) are up there from Planet, and we’ve seen other people put them up,” Skrobot said in an interview with Spaceflight Now. “And the FCC (Federal Communications Commission) is approving licenses for a lot of the big constellations coming up.”

NASA started the Venture Class Launch Services program to test the waters of the burgeoning smallsat launch market, and the space agency signed the first three VCLS launch contracts in 2015 with Rocket Lab, Virgin Orbit and Firefly Space Systems.

Rocket Lab is the first of the group to be ready for a NASA mission. Virgin Orbit’s air-dropped LauncherOne rocket is scheduled for its first orbital test flight in early 2019, and NASA plans to put a fleet of CubeSats on a subsequent LauncherOne mission next year.

NASA terminated the contract with Firefly Space Systems when the company could not meet its contractual commitments. The Texas-based company later folded, but came back under new ownership and with a new name — Firefly Aerospace — and has renewed its launcher development effort.

“With any rocket development, there are going to be some delays,” Skrobot told Spaceflight Now. “They run into issues and concerns throughout the process of developing their vehicle. We understood that. This is more us watching them develop the vehicle for the future than it is a ride for the CubeSats. Yes, we want to the CubeSats to be successful. However, from a programmatic perspective for the agency, it’s to help make sure we have this new capability for our science mission directorate or the technology directorate, the opportunity to get their missions into space at a reasonable cost.”

NASA took a hands-off approach with the Venture Class Launch Services contractors, a change from the agency’s close-up oversight of launch companies it pays to send more costly satellites into space — providers such as United Launch Alliance and SpaceX.

Rather than dispatching a team of engineers, managers and technicians to the Rocket Lab launch base in New Zealand, Skrobot said NASA sent one employee from KSC.

“The whole concept behind this is it’s an FAA-licensed (commercial) launch, so we want to keep the crews very small, so we don’t have a lot of insight and oversight,” Skrobot said. “So we went one individual, an integration engineer/mission manager-type who went down there, and we do have one contractor with him that is supporting the spacecraft.”

Rocket Lab’s launch contract with NASA is valued at $6.9 million, more than an order of magnitude less than what the space agency pays for launches on bigger rockets.

The Electron rocket can haul up to 330 pounds (150 kilograms) of payload in a polar orbit around 310 miles (500 kilometers) above Earth. The rocket’s capacity to a lower-altitude orbit is up to 500 pounds (225 kilograms).

“They may be a little higher (cost) per kilogram, but we have a dedicated vehicle,” Skrobot said of the new smallsat launch providers. Right now, we’re looking at flying payloads on ESPA (secondary payload) rings. That’s very good. But each one of those ESPA ring payloads need to go in the orbit where the primary payload is going, or somewhere a little below that. Inclination changes are very difficult to do.

“We may be paying a little bit more per kilogram (with Venture Class Launch Services), but now these smaller payloads have the ability to go to the exact orbit they really need to, in order to gain as much science as possible for the particular orbit they want. They could fly on an ESPA (secondary payload ring), but now maybe they’ll get more science out of having their own dedicated vehicles in the future,” Skrobot said.

Ten of the CubeSats set to launch on NASA’s Electron mission are part of the agency’s Educational Launch of Nanosatellites, or ELaNa, program. The Electron launch is numbered ELaNa 19, following a series of past CubeSat missions that hitched rides aboard Dragon and Cygnus supply ships bound for the International Space Station, and as secondary payloads on Antares, Atlas 5, Delta 2, Falcon 9 and Minotaur rockets.

NASA typically accepts proposals every year from CubeSat developers at U.S. universities and research organizations, then funds the launch of the best projects. Launch costs for CubeSats can sometimes match, or even exceed, the expense of building the spacecraft itself.

ELaNa 19 is the first dedicated launch for the program, which Skrobot helped kick off a decade ago. The Electron rocket and a Curie upper stage will place the 10 ELaNa-sponsored CubeSats, and three more U.S.-owned CubeSats, into a circular 310-mile-high orbit inclined 85 degrees to the equator, more than 50 miles above the orbit of the International Space Station.

The higher deployment will allow the CubeSats, ranging in mass from around 3.4 pounds (1.5 kilograms) to more than 15 pounds (7 kilograms), to remain in orbit longer than it they were released from the space station, due to the reduced atmospheric drag at higher altitudes.

“Some of the CubeSats prefer to go off ISS, those are quicker and easier, but they have to live at a lower inclination and a lower altitude. So those are probably going to last six months or a year, where as these guys here are going to last a little bit longer,” Skrobot said.

The CubeSats set for launch aboard the Electron rocket through NASA’s ELaNa program are:

  • ALBus, a 3-unit CubeSat from NASA’s Glenn Research Center in Cleveland, Ohio, will test technology for a high power density CubeSat and the deployment of solar arrays and antennas using resettable shape memory alloy mechanisms.
  • CeREs, also known as the Compact Radiation Belt Explorer, is a 3-unit CubeSat from NASA’s Goddard Space Flight Center in Greenbelt, Maryland. CeREs will examine the radiation belt and how electrons are energized and lost, particularly during events called microbursts — when sudden swarms of electrons stream into the atmosphere, according to NASA.
  • CHOMPTT, also known as the CubeSat Handling of Multisystem Precision Time Transfer mission, is a 3-unit CubeSat from the University of Florida in Gainesville, Florida. CHOMPTT will test time transfer technology using on-board atomic clocks synchronized with a ground clock using a laser signal. Time transfer is useful for satellite navigation applications.
  • CubeSail consists of two 1.5-unit CubeSats launched together, which will separate once in orbit and unspool a 250-meter (820-foot) solar sail ribbon between the two spacecraft. The CubeSail experiment was developed at the University of Illinois at Urbana-Champaign to test novel approaches to using solar sails for propulsion.
  • DaVinci is a 3-unit CubeSat from the North Idaho STEM Charter Academy in Rathdrum, Idaho. DaVinci was developed primarily as an educational tool for Idaho students, but the spacecraft also carries a camera and will test satellite-to-satellite Internet communications through the Globalstar network.
  • ISX, or the Ionospheric Scintillation Explorer, is a 3-unit CubeSat developed by SRI International and Cal Poly at San Luis Obispo, California. ISX will study plasma irregularities in the upper atmosphere by measuring its affect on digital TV signals produced on the ground.
  • NMTSat is a 3-unit CubeSat from the New Mexico Institute of Mining and Technology in Socorro, New Mexico. NMTSat carries instruments to collect data on Earth’s magnetic field and high altitude plasma density, take atmospheric weather measurements, and conduct an optical beacon experiment.
  • RSat is a 3-unit CubeSat from the U.S. Naval Academy in Annapolis, Maryland. The RSat spacecraft includes two articulating miniature robotic arms, which will be tested in orbit to assess their suitability for latching onto other satellites in orbit for inspection and repair.
  • Shields 1 is a 3-unit CubeSat from NASA’s Langley Research Center in Hampton, Virginia. Shields 1 will test new radiation shielding technologies that could be used on future small satellites.
  • STF 1, or Simulation-to-Flight 1, is a 3-unit CubeSat developed through a collaboration between NASA’s Independent Verification and Validation Program, West Virginia University, and West Virginia small businesses. STF 1 is the first spacecraft to be built in West Virginia, and it will serve as a testbed for new satellite software that can be developed on any laptop or desktop computer.

In addition to the 10 CubeSats to be launched through NASA’s ELaNa program, there are three more nanosatellites set for liftoff on top of the Electron rocket in New Zealand. NASA also provided a launch opportunity for:

  • AeroCube 11 consists of two nearly identical 3-unit CubeSats developed by the Aerospace Corp. in El Segundo, California. The AeroCube 11 mission’s two CubeSats, named TOMSat EagleScout and TOMSat R3, will test miniaturized imagers. One of the CubeSats carries a pushbroom imager to collect vegetation data for comparison to the much larger Operational Land Imager aboard the Landsat series of satellites, and the other TOMSat CubeSat has a focal plane array on-board to take pictures of Earth, the moon and stars.
  • SHFT 2, also known as the Space-Based High Frequency Testbed, is a 3-unit CubeSat owned by the Defense Advanced Research Projects Agency and developed in partnership with NASA’s Jet Propulsion Laboratory. The CubeSat launching with Rocket Lab is the second of the JPL-designed satellites, according to DARPA spokesperson Jared Adams, and will study variations in the plasma density of the ionosphere by collecting high-frequency radio signals, including those from natural galactic background emissions, from Jupiter, and from transmitters on Earth.

Rocket Lab’s Electron vehicle joins NASA’s ‘catalog’ of available launchers

NASA currently does not have any more missions booked with Rocket Lab, but the Electron rocket will be among the launcher options available to the agency’s future Explorer-class missions of opportunity, a family of science missions with costs typically capped at $55 million.

A document updated Monday attached to a recent draft call for a new NASA Explorer mission of opportunity proposals lists the Rocket Lab Electron and Virgin Orbit LauncherOne as potential rockets for missions requiring a dedicated launch.

“There are missions within NASA that are looking at these particular vehicles,” Skrobot said Tuesday. “We do offer these in our missions of opportunity. You’ll see when we start releasing our missions of opportunity for our SMEX AOs or our MIDEX AOs (small and medium-class Explorer missions), you’ll see a section in there for missions of opportunity using these types of vehicles.”

“We have Virgin and Rocket Lab in what we call our catalog, and the catalog identifies all the options for small payloads, be it a CubeSat flying in a deployer, flying on our EELV (Atlas 5, Delta 4, or Falcon 9) vehicles on an ESPA, and we also have Rocket Lab and Virgin Orbit on there as well as opportunities.

“There is still some risk with Virgin (Orbit) right now because they haven’t flown yet, so we’re keeping our eye on that and we’ll tell our customers that once they start flying we’ll have more data and we’ll be able to give them better insight into that. But now with Rocket Lab online, they’ve already had a couple of successful flights … we’ll be able to offer it to our NASA customers.”
