NASA has awarded SpaceX a contract worth more than $100 million to undertake the agency’s monitoring and data collection mission to further study the space region formed by the solar wind. It is understood that the solar wind protects the solar system from cosmic radiation from other stars. The contract will enable NASA to launch the interstellar mapping and acceleration (IMAP) satellite, which will be developed by NASA in 2018 and is expected to be launched in 2024. < / P > < p > in addition to IMAP, this mission will include four secondary payloads. Two of these missions will also be solar physics missions, and the third and fourth will be aimed at monitoring the possible impact of solar wind on the earth’s telecommunications network and studying water on the moon’s surface. SpaceX’s Falcon 9 full thrust launch vehicle will be used to launch all of these payloads, and NASA estimates the contract cost to be about $109.4 million. In addition to paying for the launch costs of the mission, the money will also cover the cost of payload integration, payload management and other services provided to the space agency. The Falcon 9 full thrust rocket is the first variant of SpaceX’s popular rocket family, which successfully landed the first stage booster in 2015. This capability gives the company a huge market share in both commercial and government payloads, and the DOD switched to this reusable variant earlier this month. The latest variant of the launch vehicle is SpaceX’s Falcon 9 block 5 launch vehicle system. The first stage of the system is equipped with nine Merlin 1D + gas generators, turboprop RP-1 rocket engines (for the first stage) and a Merlin 1 vacuum engine (for the second stage). < / P > < p > more importantly, this is the first time SpaceX has integrated the safety requirements of NASA’s commercial crew program (CCP). Earlier this year, astronauts Robert benken and ouglas Hurley boarded SpaceX’s SpaceX spacecraft. In addition, the company has redesigned the second stage of its superior fuel tanks, which were reported to have exploded on NASA’s Kennedy Space Center launch platform in 2016, destroying the $200 million satellite of Israel Aerospace Industries (IAI). < / P > < p > IMAP will be a spin stable sun tracking satellite that will orbit the star at Lagrange L1 between the sun and the earth. These satellites position themselves to the sun and use rotation as a stabilizing mechanism to control altitude. Lagrange points are the five points between any two orbiting objects where their gravity is offset, and the object placed on these coordinates needs less fuel to maintain its orbit. < / P > < p > the L1 point selected by NASA for IMAP allows the satellite to observe the sun without interference and detect solar radiation hours before it reaches the earth. If not, it is expected to move around L1 due to radiation problems, rather than placing itself on the precise coordinates of L1. It is understood that these orbits are known as Lissajous and halo orbits. Since the orbits around L1, L2 and L3 are inherently unstable, it is necessary for objects in orbit to use propulsion systems to maintain orbital parameters. < / P > < p > after launching in October 2024, IMAP will cross about 1 million mines in the solar system and reach its destination at L1 in UI. The flight is expected to take several months before it will use onboard thrusters to enter Lissajous orbit around L1. According to the program, its solar panels and rotation axis will face the sun, and its communication equipment will face the earth. < / P > < p > although it will be placed inside the solar system, it will enable NASA to understand the acceleration of solar wind particles at the edge of the heliosphere. It will do this with 10 different functional instruments on board. These missions include detecting the atoms that form solar radiation, detecting the charged particles that make up the solar wind, and instruments that can study the ultraviolet radiation emitted by magnetic fields, interstellar dust and neutral hydrogen atoms. < / P > < p > according to the current plan, SpaceX’s Falcon 9 will be launched in October 2024, and IMAP marks the company’s winning another contract with NASA. Unlike its rival, the United Launch Alliance (ULA), SpaceX has always been the center of close NASA partners. Most of ula’s orders come from the U.S. Air Force and may now come from space forces. According to launch contract data from 2005 to 2018, NASA has more than $1.5 billion with the company, which dwarfs the $500 million contract that ula received from the U.S. air force. Global Tech
