Kennedy Space Center, Florida (CNN)The launch of NASA’s historic Artemis I moon mission has been delayed after the team was unable resolve a problem that was affecting one of the four engines of the rocket.
The next chance to launch Space Launch System’s rocket and the Space Launch System rocket and Orion spacecraft on their mission is on September 2 but whether or no attempt is made will depend on how the testing goes.
“Launch controllers were continuing to evaluate why a bleed test to get the RS-25 engines on the bottom of the core stage to the proper temperature range for liftoff was not successful, and ran out of time in the two-hour launch window,” according to an update from NASA. “Engineers are continuing to gather additional data.”
The launch team needs to figure out the cause of the problem and will maintain it in the current design to collect information and determine the needs of the moment. As for both the Space Launch System rocket and Orion spacecraft, which is located on Launchpad 39B of NASA’s Kennedy Space Center in Florida are stable, as per NASA officials.
Before the scrub began, the countdown extended to an unplanned stop during which the launch team was working on a solution to the problem of one of the four engines on the rocket.
This is because the launch team found an issue with the engine bleed issue in engine #3. Reconfiguring it was unsuccessful.
In the process of removing engine bleeds the hydrogen is circulated through the engine to prepare it to launch. Four engines operate exactly as expected, however, engine #3 has a problem.
NASA Director Bill Nelson addressed the scrub shortly after the announcement and stressed it was a test flight. Artemis I is a test flight.
“We don’t launch until it’s right,” Nelson declared. “They’ve got a problem with the gases going on the engine bleed on one engine. It’s just illustrative that this is a very complicated machine, a very complicated system, and all those things have to work. You don’t light the candle until it’s ready to go.”
It’s something that Nelson has experienced personally. Being an astronaut at the time, Nelson was part of that 24th mission of the Space Shuttle. The pad was cleaned several times over the pad. the fifth attempt resulted in an unfailing mission.
“Had we launched on any one of those scrubs, it wouldn’t have been a good day,” said the captain. declared.
More details will be announced during a press conference within around four hours, per NASA.
Conditions remained favorable for launching the rocket at the start of the window that started around 8:33 a.m. ET. But a number of issues surfaced as the rocket began to fuel shortly after midnight.
Storms off the coast that could produce lightning hindered the team from starting the process of fueling, which was scheduled to begin at midnight for around an hour.
The hold was removed in 1:13 a.m. ET and the tanking process started to fill on the core of the stage supercold liquid oxygen as well as liquid hydrogen.
The team stopped refilling the tank with liquid hydrogen twice because of an initial leak , as also a pressure increase However, the tanking process continued in the main stage. It then began for the higher stage, also known as that is, the cryogenic propulsion interim stage.
The team also noticed the presence of frost along the inside of the stage flange. Initially, engineers thought that the frost could signal the presence of a crack inside the tank, however it proved to be an internal crack in the foam. The team reported that the issue was solved since the crack in the foam did not suggest any leak.
Engineers are also trying to determine what caused the delay of 11 minutes in the communication with both the Orion satellite and the ground system. The issue could have affected the time of the first terminal count, or even the countdown, which starts at the point that 10 minutes are left on the clock prior to launch.
Vice-President Kamala Harris and Second Gentleman Doug Emhoff were expected to visit the Kennedy Space Center Monday to witness the launch.
Performances by famous actors like Jack Black, Chris Evans and Keke Palmer, as well as the performance “The Star-Spangled Banner” by Josh Groban and Herbie Hancock as well as “America the Beautiful” by The Philadelphia Orchestra and cellist Yo-Yo Ma were also scheduled in the program.
Overview of mission
As Artemis I launches, Orion’s journey will run for 41 days during which it journeys to the moon, then loops around it, and then returns to Earth with in a total distance in the range of 1.3 million miles (2.1 million kilometers). As it goes back to Earth the spacecraft will crash into the Pacific Ocean off the coast of San Diego.
Although the list of passengers does not include humans however, there are passengers. Three mannequins, and the plush Snoopy toy who will be riding through Orion.
The crew on Artemis I may sound a bit odd however, they all serve an important function. Snoopy is an indicator of zero gravitywhich means that Snoopy will begin floating inside the capsule after it has reached an environment in space.
The three mannequins, Commando Moonkin Campos, Helga and Zohar, will test the depth of space radiation that future astronauts might encounter and test a brand new shielding suit and suit that is being developed. A biotechnology experiment with algae, seeds as well as yeast and fungi is in Orion to determine the reaction of life to radiation.
Cameras in and around Orion will broadcast videos and images all throughout the duration of the mission. Live footage of the Callisto experiment that will record the stream from Commander Moonikin Campos in the commanding officer’s chair. If you own an Amazon Alexa-enabled gadget, you can speak to it about the location of the mission every day.
Expect to see images of Earthrise similar to the one that was seen in Apollo 8 for the first time, but with higher quality cameras and advanced technology.
Technology demonstrations and science experiments are arranged inside a ring that is attached to the rocket. The small satellites, dubbed CubeSats can be detached and then go on their own to gather data on the moon and the deeper space environments.
The first mission in the Artemis program will begin an exploration phase in space that will land diverse astronauts in previously unexplored regions of the moon, and then will send astronauts on missions that are crewed to Mars.
The spacecraft and rocket will be put to its paces first time prior to carrying astronauts onto the moon in Artemis II and Artemis III which are scheduled to launch in 2024 or 2025, respectively.
