Northrop Grumman’s NG-15 Cygnus cargo spacecraft has been despatched on its technique to the Worldwide Area Station after hovering into orbit atop an Antares 230+ rocket.
Liftoff atop the Antares rocket happened at 12:36 p.m. EST (17:36 UTC) Feb. 20, 2021, from the Mid-Atlantic Regional Spaceport’s Pad 0A on Wallops Island, Virginia. The skies have been mostly clear for the launch with a temperature proper round freezing and some clouds.
General, the Northrop Grumman-built two-stage Antares rocket stands about 42.5 meters tall with a diameter of three.9 meters. The primary stage is powered by two RD-181 engines that devour liquid oxygen and rocket-grade kerosene whereas the second stage is a Castor 30XL stable rocket motor.
After leaving the pad, the primary stage fired for about 3.5 minutes earlier than separating and falling away.
Over the subsequent minute, the payload fairing encapsulating the Cygnus spacecraft separated to disclose the spacecraft and the interstage, which surrounded the Castor 30XL, fell away earlier than the stable motor ignited to burn for about 2.5 minutes to succeed in orbit.
Lastly, at about 9 minutes after launch, the NG-15 Cygnus was launched to start its two-day trek to the ISS.
Over the subsequent a number of hours, the 2 UltraFlex photo voltaic arrays are anticipated to deploy, giving the car the ability it wants on its journey.
As soon as NG-15 Cygnus reaches the ISS, it’ll autonomously place itself about 10 meters beneath the Future Laboratory module. Expedition 64 Flight Engineer and NASA astronaut Mike Hopkins is predicted to watch the spacecraft’s arrival as a way to guarantee its secure method.
From there, Expedition 64 Flight Engineer and Japan Aerospace Exploration Company astronaut Soichi Noguchi will command the 17.6-meter-long robotic Canadarm2 to seize the spacecraft.
Seize by the robotic arm is predicted round 4:40 a.m. EST (09:40 UTC) Feb. 22. Then over a number of hours, the arm shall be commanded to maneuver Cygnus to its berthing location on the Earth-facing port of the Unity module. Berthing is slated for about 6:40 a.m. (11:40 UTC).
After the house between the station and Cygnus is pressurized, the hatches between the spacecraft shall be opened, permitting the crew to start the lengthy strategy of unloading the car.
Inside are a multitude of fresh experiments that purpose to help future deep house exploration in addition to to profit Earth-based functions. Areas of research vary from sleep high quality to synthetic retina manufacturing to protein crystal progress. Additionally packed aboard is a choice of recent meals for the orbiting crew to take pleasure in, together with apples, oranges, cherry tomatoes and a choice of cheese.
NG-15 Cygnus is the 15th to be launched below NASA’s Business Resupply Providers contracts and the 12th within the bigger enhanced configuration.
The spacecraft’s important physique is about 6.39 meters lengthy and three.1 meters large with a mass of about 3,600 kilograms.
Following a multi-month keep on the house station, NG-15 Cygnus is predicted to be unberthed and despatched away from the outpost to start a post-ISS mission involving the deployment of a number of CubeSats.
Beneath the present plan, departure from the ISS is predicted someday in Might 2021. As soon as its mission targets are full, it’ll be commanded to deorbit over the Southern Pacific Ocean the place it’ll expend throughout reentry into Earth’s Environment.
