CAPE CANAVERAL, Fla. — The launch of NASA’s following Earth-observing Landsat satellite will certainly be postponed a week because of a scarcity of fluid nitrogen, the area company has actually introduced.
The Landsat 9 satellite, a joint undertaking by NASA and also the USA Geological Study (USGS), was initially arranged to launch from Room Introduce Facility 3 at Vandenberg Space Force Base in The Golden State on Sept. 16. That liftoff has actually been pressed back to no earlier than Sept. 23.
The hold-up is because of an around the world scarcity of fluid oxygen, a vital part of rocket gas, because of its duty in clinical fluid oxygen in the continuous COVID-19 pandemic. Fluid oxygen is made use of as an oxidizer combined with whatever gas a rocket makes use of. Landsat 9 will certainly be released on a United Introduce Partnership Atlas V rocket, which makes use of RP-1 (rocket-grade kerosene), as propellant.
“Existing pandemic needs for clinical fluid oxygen have actually affected the shipment of the required fluid nitrogen supply to Vandenberg by the Protection Logistics Company (DLA) and also its distributor Airgas,” NASA stated in a statement.

According to company authorities, NASA has its very own distributor of fluid oxygen that covers the objectives introducing from Kennedy Space Center in Florida. (It likewise offers the fluid oxygen for United Introduce Partnership objectives also; SpaceX offers its very own fluid oxygen.)
The company really has sufficient fluid oxygen products currently that the scarcity will certainly not impact any type of launches that are presently on this year’s show. That might alter depending upon the clinical area’s demands.
Releases from Vandenberg are a various tale. The problem there, as seen with the Landsat hold-up, is a scarcity of fluid nitrogen.
That’s due to the fact that the firm that supplies the supply of fluid nitrogen is helping in supplying fluid oxygen tons to medical facilities, developing an absence of shipment vehicle drivers readily available to make the distributions at Vandenberg.
“Airgas transforms the fluid nitrogen to aeriform nitrogen required for launch automobile screening and also countdown series. DLA and also Airgas currently have actually executed initiatives to raise the supply of fluid nitrogen to Vandenberg,” NASA stated in a declaration.
Landsat 9’s objective
The $885 million Landsat 9 objective will certainly be the nine in the Landsat program as its name recommends, and also will certainly proceed the program’s duty of surveillance and also handling land sources like plants, water and also woodlands.
Landsat satellites have actually been a vital source for researchers given that the very first satellite released in 1972.
“I such as to consider Landsat as something like a Pocket knife out of one fundamental collection of monitorings or dimensions, we feed an entire series of various scientific research applications,” stated Landsat 9 job researcher Jeff Masek of NASA’s Goddard Space Flight Center in Maryland, in a prelaunch objective rundown Tuesday.
The Landsat 9 satellite will certainly change the Landasat 7 satellite, which has actually remained in orbit given that 1999, and also will certainly operate in tandem with Landsat 8, which was released in 2013. The Landsat 8/9 duo will certainly picture the Planet every 8 days. They bring 2 various clinical tools that will certainly assess light mirrored from the earth in various wavelengths to find also one of the most minute modifications in the lakes, rivers and also woodland throughout the globe.
