Nasa Updates: NASA has revealed new launch dates for the unmanned Artemis I mission, which range from July to December 2022. Based on the alignment of the Earth and Moon, new timeframes for the launch of the Space Launch System (SLS) rocket and Orion spacecraft have been identified, including six brief tenures and 73 opportunities within 2022.
Apart from these, NASA has considered a number of parameters forrocket and spacecraft performance when determining the likely launch dates for Artemis I. The latest report is a welcome relief for scientists who have been working tirelessly on the launch of Artemis I, which has already experienced numerous hurdles.
NASA CANCELLED THE SLS WET DRESS REHEARSAL SCHEDULED FOR APRIL 4 LAST MONTH.
The next wet dress rehearsal, which was supposed to focus on tanking the core stage, was supposed to take place on April 14, but a leak discovered during liquid hydrogen loading operations prevented the team from finishing the test, forcing another postponement.
Ground systems teams have been working tirelessly to prepare for the launch of the Artemis I SLS rocket and Orion spacecraft from Launch Pad 39B since returning to the Vehicle Assembly Building (VAB) in late April after three failed wet dress rehearsals.
NASA has released a list of timeframes for SLS launch availability until the end of 2022, after carefully considering various criteria. NASA also published a complete calendar with available launch dates in the first part of 2023, up until June of the following year.
Aside from possible dates, the team has calculated which days provide a shorter or longer launch duration for the SLS. There are 38 to 42 long mission days in total, with 26 to 28 days indicating a short mission.
Based on the intricate orbital mechanics that allow the launch on a precise course toward the Moon, the above-mentioned frames have produced a pattern of about two weeks of launch opportunities followed by two weeks of no launch opportunities.
“The launch date must support daylight conditions for Orion’s splashdown,” the space agency said, adding that “the resulting trajectory for a given day must ensure Orion is not in darkness for longer than 90 minutes at a time.”
• On April 4, NASA cancelled the wet dress rehearsal for the SLS rocket.
• In 2022, there are six brief launch tenures available.
• The Earth’s and Moon’s alignment is a crucial element in the launch.
