Landsat 9, NASA’s most highly effective Landsat satellite tv for pc ever, is ‘hunch’ for originate on Monday
NASA has cleared its latest highly effective Earth-watching satellite tv for pc for a originate into orbit from the California cruise on Monday (Sept. 27).
The satellite tv for pc, known as Landsat 9, is heading within the correct direction to come to a decision off from the Vandenberg Home Pressure Tedious atop an Atlas V rocket equipped by the United Originate Alliance. Liftoff is concentrated for 2: 12 p.m. EDT (11: 12 a.m. PDT or 1812 GMT)
“The spacecraft, the Atlas V rocket, all differ equipment, are spellbinding,” NASA originate director Tim Dunn instructed reporters in a press conference Saturday (Sept. 25). The mission has a 30-minute window in which to come to a decision off from Vandenberg’s Home Originate Complex 3E, he added.
Four cramped cubesats will also originate into orbit with Landsat 9. Two will see the solar wind and exoplanet atmospheres as segment of NASA analysis. Two others are flying undisclosed missions for the U.S. Home Pressure, Dunn mentioned.

Landsat 9 would be the ninth and most superior satellite tv for pc to see Earth from above for the Landsat program, a joint effort by NASA and the U.S. Geological Witness that has equipped fixed imagery of our planet for virtually 50 years. It carries a high-option digicam and a sensitive infrared sensor that together can describe the Earth all the scheme by 11 spectral bands and resolve objects correct down to about 50 toes (15 meters) huge. The satellite tv for pc must restful orbit the Earth at altitude of about 438 miles (705 kilometers) over the planet’s poles.
“For virtually 50 years, Landsat satellites cling documented Earth’s altering panorama,” Michael Egan, NASA’s Landsat program manager, mentioned within the clicking conference. “Landsat 9 will enhance and variety bigger upon this unparalleled file of our home planet.”
Landsat 9 will seemingly be in a field to describe the total Earth each 16 days. When combined with knowledge from its predecessor Landsat 8, which launched in 2013 and is restful in exercise as of late, the 2 satellites can quilt the total Earth each eight days, Egan mentioned. Landsat 9 is designed to final a minimal of 5 years in orbit and change the ageing Landsat 7, which will seemingly be in exercise as of late.
Landsat satellites cling been studying the Earth since 1972. That continuous coverage is key to tracking Earth’s changes, in particular because the planet experiences more rude climate, highly effective storms, fires and varied outcomes from climate alternate, mission officials mentioned.
“As we know, climate alternate is true,” mentioned Tanya Trujillo, Assistant Secretary for Water and Science on the Division of the Interior within the clicking conference. “The Landsat program is an shapely tool to motivate knowledge our efforts to attain and record the changes we’re seeing on a day-to-day basis.”
Northrop Grumman built the $750 million Landsat 9 for NASA, with the mission’s crew shaving about $90 million off its preliminary funds, Thomas Zurbuchen, NASA’s affiliate administrator for science missions, instructed reporters Saturday.
It’s been a lengthy motorway to the launchpad for Landsat 9. The satellite tv for pc was once first and major speculated to originate on Sept. 16, but was once delayed to Sept. 23 on account of a liquid nitrogen scarcity associated to the ongoing COVID-19 pandemic. Excessive winds prompted one other delay to Sept. 27.
The mission will also originate a minute later than deliberate to stay some distance off from a collision probability with NASA’s Calypso/CloudSat satellite tv for pc in orbit, Dunn mentioned. For the time being, climate forecasts predict a 60% probability of factual prerequisites at originate time.
If NASA and the United Originate Alliance are unable to originate Landsat 9 on Monday, a backup originate window is available on Tuesday, with the same climate prerequisites expected.
