Electron looks a little different for the #ReturntoSender mission. For the first time, we'll be attempting to bring Electron's first stage back to Earth under a parachute after launch.

We're counting down to the #ReturnToSender mission on 19 Nov UTC! Final checkouts are underway, the recovery team is primed, and Electron is almost ready to go to space again. We're lucky to have such a dedicated team and incredible customers behind every mission.

This unspecified ship appears to be the vessel charged with recovering Electron tonight.

I don't have any visibility over it at the moment to get more details.

The #ReturnToSender mission will launch New Zealand's first student-built satellite, APSS-1, designed and built by students of @AucklandSpace at @AucklandUni. We're providing the ride to orbit at no cost. Learn more about APSS-1: https://bit.ly/36I42Fz

APSS-1 is designed to measure electrical activity in the upper atmosphere. It aims to help scientists understand to what extent and how the ionosphere is affected by geophysical activity on Earth, including whether electrical disturbances might be correlated with earthquakes.

On its next mission, Rocket Lab will try to recover the first stage of its Electron small satellite launcher after parachuting into the Pacific Ocean downrange from the company's privately-run spaceport in New Zealand.

The attempt to retrieve the Electron rocket's first stage moves Rocket Lab closer to eventually capturing falling boosters in mid-air with a helicopter, then reusing the hardware. The reuse initiative is aimed at increasing Rocket Lab's flight rate, and could result in cost savings, according to Peter Beck, the company's founder and CEO.

Rocket Lab, a California-based launch company, initially planned to try to recover an Electron booster for the first time on its 17th mission. It's now planning to attempt the feat on the company's next launch -- the 16th flight of an Electron rocket since it debuted in 2017.

Engineers have completed a series of tests since last year, first demonstrating the carbon composite Electron booster can withstand the heating and structural loads of re-entering the atmosphere. Rocket Lab performed the re-entry experiment on two Electron flights in December 2019 and January 2020.

Then the company earlier this year tested the ability of a helicopter to snag a mock-up of an Electron first stage in mid-air. Since then, Rocket Lab completed a series of drop tests of the booster's parachute system, which Beck said the company developed in-house.

"It's not very often in the space industry you pull something forward, but this mission we are," Beck said. "This is a huge milestone mission for us. This is the first time we're actually going to do everything but capture it under a helicopter. So we will once again re-enter the stage -- re-orientate it first -- and then re-enter it while maintaining the re-entry corridor."

After plunging into the thick, lower layers of the atmosphere -- "hitting the wall," as Beck calls it -- the booster will deploy a pilot parachute, a drogue chute, and then a circular main chute. The rocket's parachutes will "hopefully bring it under a nice stable descent descent and splash it down into the ocean," Beck said.

Recovery vessels stationed near the booster's splashdown zone around 250 miles (400 kilometers) south of the launch site will move in to secure the first stage and hoist it onto a ship for return to New Zealand.

"This is kind of an all-up combined test at the conclusion of a number of tests we've been going over the last 12 months," Beck said. "So we'll look forward to seeing what we've really got."

All of the system tests and sub-scale demonstrations so far have showed Rocket Lab is on track to recover the rocket, Beck said. But this will be the first time engineers put all the systems together on a single test, and then fly the rocket through the atmosphere at hypersonic speed.

"I'll stop being nervous once we get it back in the factory, but until then I think there's just a lot that has to work," Beck said in a conference will with reporters.

Millennium Space Systems, a Boeing subsidiary, built two small satellites awaiting launch Thursday night on a Rocket Lab Electron rocket on a mission to test the effectiveness of a drag-inducing device that could help remove spacecraft from orbit.

The two small satellites are part of the DragRacer mission, which is set to launch with a cluster of payloads on a Rocket Lab Electron vehicle during a window opening at 8:46 p.m. EST Thursday (0146 GMT) and closing at 11:34 p.m. EST (0434 GMT).

The window opens at 2:46 p.m. local time Friday at Rocket Lab's launch site, located on the North Island of New Zealand.

For the first time, Rocket Lab will attempt to recover the first stage[/b] of the Electron rocket with a parachute. A successful recovery would push the California-based launch company closer to reusing rocket boosters.

The DragRacer experiment includes two satellites -- built by Millennium Space Systems -- that will separate shortly after launching on the Electron rocket in a 310-mile-high (500-kilometer) sun-synchronous orbit. 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 and naturally 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.

Rocket Labs' Recovery ship 'Catch of the Day' is stationed 650 km downrange from the launch pad in preparation for the launch attempt in just under two hours.

The ship will attempt to recover Electron 1st stage from the water after splashdown.
