Watch Live Wednesday: Rocket Lab’s R3D2 Launch
Editor’s note: NASA’s broadcast of the fifth National Space Council has ended. During the meeting, Vice President Mike Pence called on NASA to land astronauts on the moon in 2024, five years from now, using all means at its disposal. Read our full story.
Update for Tuesday, March 26:
Rocket Lab has postponed its Sunday launch attempt of an Electron booster carrying DARPA’s experimental R3D2 satellite due to a video transmitter issue. Rocket Lab: “The team has identified a video transmitter 13dB down with low performance. It’s not an issue for flight, but we want to understand why, so we’re waiving off for the day.” The mission will launch no earlier than Wednesday, March 27, at 6:30 p.m. EDT (2230 GMT) during a four-hour window.

The R3D2 satellite was built by DARPA (Defense Advanced Research Projects Agency) to test new communications technology in space. Its launch will be Rocket Lab’s first flight of 2019.
From DARPA: “R3D2 will monitor antenna deployment dynamics, survivability and radio frequency (RF) characteristics of a membrane antenna in low-Earth orbit. The antenna could enable multiple missions that currently require large satellites, to include high data rate communications to disadvantaged users on the ground. A successful demonstration also will help prove out a smaller, faster-to-launch and lower cost capability, allowing the Department of Defense, as well as other users, to make the most of the new commercial market for small, inexpensive launch vehicles. Satellite design, development, and launch took approximately 18 months.”
Huntington Beach, California. January 22, 2019 – Small satellite launch company Rocket Lab announced today that its first mission of 2019 will be a dedicated launch of a 150kg satellite for the Defense Advanced Research Projects Agency (DARPA). The mission highlights US Government demand for the type of responsive, ultra-flexible and rapidly acquired launch service that characterizes the Rocket Lab launch experience on Electron.
DARPA’s Radio Frequency Risk Reduction Deployment Demonstration (R3D2) mission is scheduled for launch in late February and intends to space-qualify a prototype reflect array antenna to improve radio communications in small spacecraft. The antenna, made of a tissue-thin Kapton membrane, packs tightly inside the small satellite for stowage during launch, before deploying to its full size of 2.25 meters in diameter once it reaches low Earth orbit. This high compaction ratio enables larger antennas in smaller satellites, enabling satellite owners to take advantage of volume-limited launch opportunities while still providing significant capability. The mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet.
“Rapid acquisition of small satellite launch capabilities is increasingly important to US Government organizations like DARPA. The ability to rapidly space-qualify new technology and deploy space-based assets with confidence on short notice is a service that didn’t exist for dedicated small satellites until now,” says Rocket Lab founder and CEO Peter Beck. “We’re honored to provide Electron’s agile and flexible launch service to DARPA and we look forward to delivering the innovative R3D2 payload to orbit.”
The mission, the first of monthly Electron launches this year, will lift-off from Rocket Lab Launch Complex 1 on the Māhia Peninsula of New Zealand. To ensure precise insertion and responsible orbital deployment, the R3D2 payload will be deployed via the Electron Kick Stage to a circular orbit. Using this unique launch method, Electron’s second stage is left in a highly elliptical orbit where the stage is subject to significant atmospheric drag, causing it to de-orbit and burn up to nothing in a reduced time frame. The Kick Stage is then used to deploy the satellite payload to a precise orbit, following which the Kick Stage can perform a de-orbit burn to speed up its re-entry, leaving no orbital debris behind in space.
The Rocket Lab Electron launch experience is the world’s first customized small satellite launch service. With the choice of two Rocket Lab launch sites, and the ability to rapidly launch to orbit as frequently as every 72 hours, each mission is tailored to the customer requirements. For the first time, small satellite customers are enjoying unmatched flexibility, responsiveness and control over their own orbit.

A successful demonstration also will help prove out a smaller, faster-to-launch and lower cost capability, allowing the Department of Defense, as well as other users, to make the most of the new commercial market for small, inexpensive launch vehicles. Satellite design, development, and launch took approximately 18 months.
“The Department of Defense has prioritized rapid acquisition of small satellite and launch capabilities. By relying on commercial acquisition practices, DARPA streamlined the R3D2 mission from conception through launch services acquisition,” said Fred Kennedy, director of DARPA’s Tactical Technology Office. “This mission could help validate emerging concepts for a resilient sensor and data transport layer in low Earth orbit – a capability that does not exist today, but one which could revolutionize global communications by laying the groundwork for a space-based internet.”
The launch will take place on a Rocket Lab USA Electron rocket from the company’s launch complex on the Mahia Peninsula of New Zealand. Northrop Grumman is the prime contractor and integrated the 150 kg satellite; MMA Design designed and built the antenna. Trident Systems designed and built R3D2’s software-defined radio, while Blue Canyon Technologies provided the spacecraft bus.

Live HD Views of Earth from Space
You can watch live, high-definition views of Earth from the International Space Station thanks to NASA’s High Definition Earth Viewing experiment (HDEV). This live video provides alternating views from four of the station’s external cameras nearly 24/7, with the exception of regular and temporary dropouts that occur when the station switches its connection between different communications satellites. Watch it live in the window above, courtesy of NASA TV.
“Behold, the Earth! See live views of Earth from the International Space Station coming to you by NASA’s High Definition Earth Viewing (HDEV) experiment.
“While the experiment is operational, views will typically sequence through the different cameras. If you are seeing a black image, the Space Station is on the night side of the Earth. If you are seeing an image with text displayed, the communications are switching between satellites and camera feeds are temporarily unavailable. Between camera switches, a black & gray slate will also briefly appear.
“The experiment was activated on April 30, 2014 and is mounted on the External Payload Facility of the European Space Agency’s Columbus module. This experiment includes several commercial HD video cameras aimed at the Earth which are enclosed in a pressurized and temperature controlled housing. To learn more about the HDEV experiment, visit: https://eol.jsc.nasa.gov/ESRS/HDEV/
“Please note: The HDEV cycling of the cameras will sometimes be halted, causing the video to only show select camera feeds. This is handled by the HDEV team, and is only scheduled on a temporary basis. Nominal video will resume once the team has finished their scheduled event.”
‘ISS Live!’ Tune in to the International Space Station
Find out what the astronauts and cosmonauts aboard the International Space Station are up to by tuning in to the “ISS Live” broadcast. Hear conversations between the crew and mission controllers on Earth and watch them work inside the U.S. segment of the orbiting laboratory. When the crew is off duty, you can enjoy live views of Earth from Space. You can watch and listen in the window below, courtesy of NASA.
“Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During ‘loss of signal’ periods, viewers will see a blue screen.
“Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below.”
