ЦитатаAround the Moon with NASA's First Launch of SLS with Orion
Artemis I, formerly Exploration Mission-1, will be the first integrated test of NASA's deep space exploration systems: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida. The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight test that will provide a foundation for human deep space exploration, and demonstrate our commitment and capability to extend human existence to the Moon and beyond.
During this flight, the spacecraft will launch on the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown. It will travel 280,000 miles from Earth, thousands of miles beyond the Moon over the course of about a three-week mission. Orion will stay in space longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before.
"This is a mission that truly will do what hasn't been done and learn what isn't known," said Mike Sarafin, Artemis I mission manager at NASA Headquarters in Washington. "It will blaze a trail that people will follow on the next Orion flight, pushing the edges of the envelope to prepare for that mission."

Leaving Earth
SLS and Orion will blast off from Launch Complex 39B at NASA's modernized spaceport at Kennedy Space Center in Florida. The SLS rocket is designed for missions beyond low-Earth orbit carrying crew or cargo to the Moon and beyond, and will produce 8.8 million pounds of thrust during liftoff and ascent to loft a vehicle weighing nearly six million pounds to orbit. Propelled by a pair of five segment boosters and four RS-25 engines, the rocket will reach the period of greatest atmospheric force within ninety seconds. After jettisoning the boosters, service module panels, and launch abort system, the core stage engines will shut down and the core stage will separate from the spacecraft.
As the spacecraft makes an orbit of Earth, it will deploy its solar arrays and the Interim Cryogenic Propulsion Stage (ICPS) will give Orion the big push needed to leave Earth's orbit and travel toward the Moon. From there, Orion will separate from the ICPS within about two hours after launch. The ICPS will then deploy a number of small satellites, known as CubeSats, to perform several experiments and technology demonstrations.

On to the Moon
As Orion continues on its path from Earth orbit to the Moon, it will be propelled by a service module provided by the European Space Agency, which will supply the spacecraft's main propulsion system and power (as well as house air and water for astronauts on future missions). Orion will pass through the Van Allen radiation belts, fly past the Global Positioning System (GPS) satellite constellation and above communication satellites in Earth orbit. To talk with mission control in Houston, Orion will switch from NASA's Tracking and Data Relay Satellites system  and communicate through the Deep Space Network. From here, Orion will continue to demonstrate its unique design to navigate, communicate, and operate in a deep space environment.
The outbound trip to the Moon will take several days, during which time engineers will evaluate the spacecraft's systems and, as needed, correct its trajectory. Orion will fly about 62 miles (100 km) above the surface of the Moon, and then use the Moon's gravitational force to propel Orion into a new deep retrograde, or opposite, orbit about 40,000 miles (70,000 km) from the Moon.
The spacecraft will stay in that orbit for approximately six days to collect data and allow mission controllers to assess the performance of the spacecraft. During this period, Orion will travel in a direction around the Moon retrograde from the direction the Moon travels around Earth.
Return and Reentry
For its return trip to Earth, Orion will do another close flyby that takes the spacecraft within about 60 miles of the Moon's surface, the spacecraft will use another precisely timed engine firing of the European-provided service module in conjunction with the Moon's gravity to accelerate back toward Earth. This maneuver will set the spacecraft on its trajectory back toward Earth to enter our planet's atmosphere traveling at 25,000 mph (11 kilometers per second), producing temperatures of approximately 5,000 degrees Fahrenheit (2,760 degrees Celsius) - faster and hotter than Orion experienced during its 2014 flight test.
After about three weeks and a total distance traveled exceeding 1.3 million miles, the mission will end with a test of Orion's capability to return safely to the Earth as the spacecraft makes a precision landing within eyesight of the recovery ship off the coast of Baja, California. Following splashdown, Orion will remain powered for a period of time as divers from the U.S. Navy and operations teams from NASA's Exploration Ground Systems approach in small boats from the waiting recovery ship. The divers will briefly inspect the spacecraft for hazards and hook up tending and tow lines, and then engineers will tow the capsule into the well-deck of the recovery ship to bring the spacecraft home...

The third of five sets of solid rocket boosters for NASA's Space Launch System (SLS) rocket were placed on the mobile launcher inside the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. The middle segments, painted with the iconic "worm" logo, were lifted onto the launcher by Jacobs and Exploration Ground Systems engineers using the VAB's 325-ton crane.
The twin boosters will power the first flight of the agency's new deep space rocket on its first Artemis Program mission. Artemis I will be an uncrewed flight to test the SLS rocket and Orion spacecraft as an integrated system ahead of crewed flights.

ЦитатаRichard Stephenson  @nascom1
DSN Operations is currently being inundated by new missions and with it the need for interface and compatibility testing. Artemis 1 will be deploying 13 6U cubesats as a secondary payload. Its keeping us busy and hopefully explains some strange mission acronyms on DSN Now

BioSentinel gets a step closer to flight. Having completed assembly and a battery of tests, the BioSentinel team at NASA's Ames Research Center in California's Silicon Valley is in the final stretch of preparations to ship the spacecraft to NASA's Kennedy Space Center in Florida for launch. BioSentinel's deep space flight will go past the Moon and into an orbit around the Sun. It's one of 13 CubeSats that will launch aboard Artemis I, the first flight of the Artemis program's Space Launch System. Here, inside an anechoic chamber at Ames, quality assurance engineer Austin Bowie inspects BioSentinel's solar array after completion of a test to determine the effects of electromagnetic spacecraft emissions on spacecraft systems.

BioSentinel scientist Lauren Liddell uses a microscope to count yeast cells to ensure the correct number of cells are loaded into BioSentinel's microfluidic hardware. Because human cells and yeast cells have many similar biological mechanisms, including for DNA damage and repair, BioSentinel's experiments can help us better understand the radiation risks for long-duration deep space human exploration.

BioSentinel will test new technology with the BioSensor payload, a kind of "living radiation detector." At the heart of the BioSensor are the microfluidic cards that house yeast cells. As the cells get activated in space, they will sense and respond to the damage caused by space radiation. Here, a BioSentinel team member works on assembling a BioSensor payload, connecting thermal and optical units to a microfluidic card. During BioSentinel's experiments, these components will warm the cards - and the yeast cells they house - and measure growth and activity in response to space radiation damage.

BioSentinel mechanical and structures lead Abraham Rademacher, left, integration and test lead Vaslie Manolescu, center, and electrical engineer James Milsk perform a solar array deployment and gimbal motion test on the spacecraft in a clean room at Ames. The test ensures that the spacecraft's solar arrays will operate correctly in flight. BioSentinel's mission builds on Ames' history, combining the center's strengths in space biology and CubeSat technology. Following 15 years of Ames' experience in developing and flying CubeSats that carried and studied living microbes in low-Earth orbit, BioSentinel will be the first CubeSat to run a biology experiment in deep space.

Integration and test engineer Dan Rowan works on internal components of BioSentinel's CubeSat in a clean room at Ames. These "spacecraft guts" include a radio, batteries, other spacecraft subsystems, and BioSentinel's two instruments - the BioSensor payload and a radiation detection instrument. The latter measures and characterizes the radiation environment; its results will be compared to the BioSensor payload's biological response.
