Mohammad Javad Azari Jahromi, Iran's telecommunications minister, denied a failed satellite launch and offered no further explanation for the activity at the Imam Khomeini Spaceport.
Scientists used a fiery wind tunnel to find out how satellites break apart when they leave orbit and fall back to Earth.
The rocket will be carrying three national security payloads for the National Reconnaissance Office.
On March 24, 2006, the company launched its first Falcon 1 rocket, but the mission was unsuccessful.
SpaceX is planning to deploy tens of thousands of Starlink satellites in low Earth orbit.
The object, which is estimated to measure between 15-33 feet across, was discovered on September 17, 2020.
Russian state media reported that a little-known private space firm called Success Rockets was planning to launch 558 satellites.
The combined mass of both objects is roughly 2.8 metric tons.
Wildfire smoke from the west coast has reached as far east as the Great Lakes region.
"It's almost a complete disaster," said Chris Luz, the mayor of Phoenix, Oregon.
The South Atlantic Anomaly was discovered in the 1950s and appears to be splitting into two patches.
Saturday's Falcon 9 rocket launch is scheduled for lift off, weather permitting, at 5:21 a.m. EDT.
The experimental system is designed to keep the antennae of the satellites in the shade, thereby preventing sunlight from reflecting off them back to Earth.
"I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," said NASA scientist Pawan Gupta.
Starlink is a project that involves sending thousands of mass-produced satellites into orbit with the aim of providing high-speed internet coverage across the globe.
The newest branch of the American military is reportedly developing a suite of ground weapons that can jam satellite signals during orbital conflict.
These projects could have a significant effect on wide-field surveys which are key for observing potentially hazardous asteroids.
If the two objects did collide, "there would be thousands of pieces of new debris that would stay in orbit for decades," said Dan Ceperley from LeoLabs.
The aim of Starlink is to provide global internet coverage from space with very short lag times.
The FCC filed paperwork with the International Telecommunication Union (ITU) on behalf of SpaceX, requesting permission for the production and deployment of 30,000 Starlink satellites.
Geomagnetic jerks were first discovered in the 1970s—but their cause has been unknown until now.
The company hopes it will be able to accommodate space-tourists by 2022.
The anti-satellite weapons are part of massive pushes to upgrade and update their militaries.
"We've had space junk falling out of the sky on a regular basis."
The harpoon could tug the 9-ton Envisat towards the atmosphere.
The FCC ruled the firm's tiny satellites were too small to be adequately monitored, and risked collision with other spacecraft.
