Astra\u2019s small satellite launcher returned to flight Tuesday and delivered an unspecified number of small satellites into orbit after a successful liftoff from Alaska, helping clear the way for a series of three launches for NASA in the coming months at Cape Canaveral.<\/p>\n

The 43-foot-tall (13.1-meter) launcher, named Rocket 3.3, lifted off from the Pacific Spaceport Complex on Kodiak Island, Alaska, at 12:22 p.m. EDT (1622 GMT; 8:22 a.m. AKDT) Tuesday. Astra scrubbed a launch attempt Monday due to the threat of lightning at the spaceport.<\/p>\n

The rocket\u2019s five kerosene-fueled Delphin engines fired nearly three minutes to guide the launcher south from Kodiak Island. Then the rocket shed its payload fairing, or nose cone, and the second stage separated to light its Aether engine for a nearly six-minute burn to accelerate into orbit.<\/p>\n

Astra officials quickly confirmed the rocket reached orbit less than 10 minutes after liftoff, but the company waited to declare success until ground teams began contacting the CubeSats deployed on the mission.<\/p>\n

\u201cWe have just started to hear back from our customers\u2019 payloads, and we have great news to report,\u201d said Chris Kemp, Astra\u2019s co-founder and CEO. \u201cThe payloads have started to communicate with ground stations. Our customers are calling us and indicating that their satellites are alive. They\u2019re talking, which means they\u2019ve been successfully deployed.\u201d<\/p>\n

U.S. military tracking data indicated the mission reached an orbit ranging between 292 miles and 333 miles (471-by-537 kilometers), with an inclination of 97.5 degrees to the equator.<\/p>\n

\u201cThe flight was nominal,\u201d Kemp said. \u201cWe were able to precisely deliver to the targeted orbit and inclination at orbital velocity.\u201d<\/p>\n

The mission\u2019s customer was Spaceflight, a commercial launch broker and an arranger of rideshare launch services. Spaceflight said it had three of its customers flying on Astra\u2019s Rocket 3.3 launch vehicle, designated Launch Vehicle 0009, or LV0009. Two of the customers were Portland State Aerospace Society and NearSpace Launch, while the third was undisclosed.<\/p>\n

Portland State Aerospace Society\u2019s payload, named OreSat0, is a student-built nanosatellite developed at Portland State University in Oregon. NearSpace Launch\u2019s payload, named S4 CROSSOVER, remained attached to the Astra rocket\u2019s second stage after entering orbit, testing communications instruments and gathering data on the space environment.<\/p>\n

The launch of LV0009 marked Astra\u2019s return to Kodiak Island, where the company based its first four orbital launch attempts. The first three test flights failed to reach orbit, but Astra successfully placed an inert payload into orbit for the U.S. Space Force in November.<\/p>\n

That set the stage for Astra\u2019s first mission with functional satellites on-board, which took off Feb. 10 from Cape Canaveral Space Force Station. But a problem during separation of the rocket\u2019s payload shroud, followed by a software glitch on the upper stage, prevented the mission from completing its mission.<\/p>\n

Astra said March 6 that the launch from Florida last month failed to reach orbit after the rocket\u2019s payload fairing did not fully open nearly three minutes after liftoff.<\/p>\n

The two halves of the clamshell-like nose cone on Astra\u2019s rocket were supposed to jettison after shutdown of the vehicle\u2019s first stage engines, revealing the rocket\u2019s second stage and satellite passengers to continue the climb into orbit.<\/p>\n

Astra said an investigation led by company engineers, with oversight from the FAA, revealed that the payload fairing\u2019s five separation mechanisms fired in the wrong order due to an electrical issue. That led to unexpected movement of the fairing structure, causing an electrical disconnection that prevented the final separation mechanism from receiving its command to open.<\/p>\n

On-board video from the rocket showed the payload fairing start to open, but the two halves never fully separated to fall away from launch vehicle. That meant the upper stage lit its engine while still inside the fairing.<\/p>\n

In a separate issue, Astra said engineers discovered a software problem that caused the upper stage to begin tumbling after firing away from the first stage and malfunctioning payload fairing.<\/p>\n

Astra said the root cause of the payload fairing separation failure was an error in an engineering drawing, which caused technicians to improperly install wiring harnesses on the fairing separation system. Testing did not detect the problem before launch.<\/p>\n

The software problem was rooted in a vulnerability to a \u201cpacket loss\u201d failure mode, according to Astra. \u201d A missed series of signals resulted in a chain of events, resulting in the upper stage\u2019s inability to recover from its tumble,\u201d the company said in a statement.<\/p>\n

Officials updated the engineering drawing and modified the payload separation system wiring harnesses on rockets already built in Astra\u2019s factory, and introduced a new test to detect similar issues in the future. Engineers also upgraded software to overcome the problem that paralyzed the steering system ion the upper stage.<\/p>\n

\u201cThis has not been easy,\u201d Kemp said after Tuesday\u2019s launch. \u201cWe had a flight just over a month ago, and the team worked really hard every day, every weekend, many nights to quickly identify the issues we had on that flight, get another rocket back up to Kodiak, and fly it, and it was absolutely the right thing to do.<\/p>\n

\u201cI\u2019m so proud of the team,\u201d Kemp said. \u201cI\u2019m so grateful for our shareholders who\u2019ve been patient with us, the customers who stuck with us and flew these these satellites just a few weeks later on this rocket and we couldn\u2019t be more excited to continue to deliver for our customers.\u201d<\/p>\n

The LV0009 mission from Alaska was critical for Astra, which aims to eventually launch daily missions to carry small satellites into orbit for a range of customers, including the U.S. military, commercial companies, and NASA. With Tuesday\u2019s flight, the company has successfully reached orbit in two of six tries.<\/p>\n

After the LV0009 mission, Astra plans to return to Cape Canaveral for a series of three launches for NASA in April and May, carrying NASA\u2019s TROPICS CubeSats.<\/p>\n

TROPICS, a weather research mission, stands for Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats. The mission will consist of six CubeSats flying in three orbital planes, with each Astra launch targeting a specific orbit in the constellation.<\/p>\n
