A primary-of-its-kind climate satellite tv for pc must wait no less than 24 hours to start its mission for NOAA and NASA after a rocket difficulty prevented an tried liftoff from Vandenberg Air Force Base in California right now (Nov. 14).
The Joint Polar Satellite System-1 satellite tv for pc, or JPSS-1, was set to launch right into a polar orbit round Earth at four:47 a.m. EST (0947 GMT) to start measuring atmospheric temperature, moisture, ozone ranges, vegetation and rainfall throughout the globe with 5 superior devices. But a foul studying on the primary stage of satellite tv for pc’s United Launch Alliance Delta II rocket, in addition to boats within the security zone, pressured NASA to name off the launch simply minutes earlier than liftoff. The subsequent launch try will probably be on Wednesday (Nov. 15) at four:47 a.m. EST.
“Just at the time we were expected to come out of hold at T-4 minutes, there were a couple of positions that reported that they were no-go, and with the very short launch window that we have this morning, there was not enough time to completely work the issues and clear them,” NASA spokesperson Mike Curie stated at about four:43 a.m. EDT (0943 GMT) throughout reside commentary. “The rocket is in a safe condition, the spacecraft, JPSS-1, is in a safe condition.” [Satellite Quiz: Do You Know What’s Up There?]
The Delta II rocket’s window to launch JPSS-1 into the right orbit was simply over a minute lengthy.
NASA launch supervisor Omar Baez confirmed that up till four minutes earlier than liftoff, the one difficulty launch controllers have been monitoring have been just a few boats within the boat exclusion space off the coast close to Vandenberg Air Force Base, however then one parameter on the primary stage additionally went out of limits.
“There was some discussion, short, brief discussions, but with our short window there wasn’t enough time to outbrief that issue and come to resolution,” he stated. “We’re setting up for a 24-hour recycle; tomorrow’s window will start one second later, at 9:43:03, versus :02, which was today’s start, and the same window. That’s where we stand today.”
In addtion to the JPSS-1 satellite tv for pc, the Delta II rocket can be slated to heft 5 small cubesats into orbit, together with one that might use a microwave imager to observe Earth’s climate like its a lot bigger satellite tv for pc cousin.
NASA will webcast the JPSS-1 satellite tv for pc launch on Wednesday, starting at four:15 a.m. EST (0915 GMT). You can watch the launch reside right here, courtesy of NASA TV.
