NASA is set to launch a long-awaited Florida satellite on Wednesday night designed to help scientists predict how the sky will work above Earth. But once we get there, the launch spacecraft of this satellite from the Earth will not rise like the others. Instead, I launch it under the wing of a large aircraft and determine the wind speed.
The mission is called ICON – for the Ionospheric Connection Network – and will initially be launched in the summer of 2017. However, technical and rocket problems, dubbed Pegasus, forced the launch to be held for the past two years. Now, Northrop Grumman, who runs the Pegasus system, says the planet is ready to fly after two changes to the vehicle and control various signal types.
If ICON came out of Earth this week, scientists would be very concerned about the satellite’s information to us about the Earth’s surface – a huge layer of our planet’s surface. starting from 30 km high. They cover up to 600 km. height. This part of your planet’s surface is attached to the spacecraft that has the responsibility for the known sky. Here the particles that flew from the Sun interact with the particles of the atmosphere, collecting and creating different shapes such as aurora and geomagnetic storms.
The challenge, however, is how scientists find it difficult to predict how an ion will behave. “What we do know about climate change is that it varies from day to day,” says Thomas Immel, chief investigator for ICON at the University of California at Berkeley. The label. “And another thing we know is that the symptoms are difficult to predict.”
That’s a problem, because time-lapse meetings can have a huge impact on electricity and systems here in the World. Many satellites fly through the atmosphere and astronauts at the International Space Station. GPS signals also go through this area. Environmental disturbances can model these signals with these devices, including blocking our electrical current on the lower surface.
One way to help predict weather forecasts is to photograph the Sun and understand how NASA performs and other types of activities such as the Parker Solar Probe. But now, it is still difficult to understand how the weather responds to the events of the day. It can be difficult to plan storms and other weather conditions. “I would be really impressed with how little time you can plan your days, if you don’t know about the weather tomorrow,” Immel says, “this is a situation we have in mind.
To better understand this space segment, the ICON mission team is sending the satellite deep into the objects. The vehicle will reach a height of 360 kilometers, just above the surface of the atmosphere, about 120 to 200 kilometers, according to Immel. ICON will also send the Earth to low latitudes throughout the world, where the spacecraft are located. “We’re focusing on that area because that’s all there is to it,” Immel says.
ICON is very similar to the hardware devices designed to increase their understanding of the purpose of ionotara. The satellite measures the temperature and air of the plasma and the particles in this area, and the vehicle also measures the atmosphere for the density, and all the chemicals present. They measure the brightness of the atmosphere, which indicates how the atmosphere moves through space. All of these measurements can be used as good models for how the ion works at all times. “We are looking to provide consultants with ideas on what to do to better predict future global warming,” Immel says.
While they were at the scene, ICON sat down with a mission called GOLD, started in January 2018. GOLD is a NASA device attached to a commercial satellite 22,000 miles above the Earth’s surface. From this perspective, GOLD has collected the above nitrogen information from above. Working together, the two missions will provide different information about the climate of different areas.
“We’re looking at a time similar to the nature of the hurricane,” Immel said during a previous press conference. «Where is the VA [pronóstico del tiempo] Satellites provide high-resolution images, and planes take turns in orbits to model themselves and retrieve information. And that’s what ICON and GOLD can combine to work for some time. »
ICON is expected to work with GOLD in advance, as it was originally scheduled for launch in 2017 and in 2018 from Kwajalein Atoll. The initial launch was delayed due to concerns that parts of the Pegetus storage may not be separated during the mission, while the second flight was released after some noise was not detected in the the powers of the rock. The launch was postponed to Cape Canaveral, Florida, and is scheduled for October 2018, but there were still some noise problems.
Since then, Northrop Grumman has identified a number of causes of noise problems that have changed some of the electronics and equipment to fix the problem. “I would like to apologize for the inconvenience, which has been going on for the past 11 months,” Omar Báez, NASA’s Chief Executive Officer for the Launch Service Project at the Kennedy Space Center, said during a press conference at before launch. But we wanted to be right on this rocket.
While waiting, the ICON team checks the ICON regularly to make sure it is still working at the scheduled time. The engineers removed the vehicle from the tire tray, all the equipment was turned on, to make sure all the original work was done as expected. “We have good expectations for the big mission,” Immel says.
The ICON launch is scheduled for Oct. 9 at 9:30 PM ET in Florida. The rock Pegasus “separates” under the wing of its pilot, a Lockheed L-1011 TriStar or Stargazer, and rolls over the Athenian Sea. When the plane got to the top, the boundary fell, I let go of Pegasus, turned its main engine and turned into the economy. This method is known as launching in the air, and is a very rare way to access space. There are just a few other companies planning to try this kind of technique – especially the Virgin Galactic, the start of a company called Virgen de la Órbita.
NASA coverage for ICON launch will be live at 9:15 PM ET. The weather is not very good for the mission because only 30 cycles will make the conditions better. If this mission does not meet the requirements, Northrop Grumman will set a launch date on Thursday, October 10. The team is currently in good working order, so check back later to see if it changes. this mission delayed to the point.
