Consider a US Air Force launch of its latest GPS satellite from Cape Canaveral. Radar tracking shows the following J2000 state vector (X,Y,Z and Vx,Vy,Vz) at burnout.

Calculate the minimum total delta V required to maneuver this spacecraft into a circular orbit with a 12-hour period and an inclination of 61 degrees, assuming impulsive maneuvers and two-body dynamics.
Please solve using equations from Howard Curtis's Orbital Mechanics for Engineering Students, 4th Edition. Or if not possible name the equations you use. If you could solve with specific angular momentum "h", earth gravitational parameter "mu", semimajor axis "a", and the target velocity for orbit "v_target".
Also please use matlab syntax for solving or write the equations out clearly. Thanks!

- In the Check Your Learning section of Example 27.1, you were told that several lines of hydrogen absorption in the visible spectrum have rest wavelengths of 410 nm, 434 nm, 486 nm, and 656 nm. In a spectrum of a distant galaxy, these same lines are observed to have wavelengths of 492 nm, 521 nm, 583 nm, and 787 nm, respectively. The example demonstrated that z=0.20 for the 410 nm line. Show that you will obtain the same redshift regardless of which absorption line you measure.arrow_forwardWe receive today the light from a distant galaxy and from its spectrum we conclude that it took 400 Myr for the photons to reach us. Which one of the following statements is correct? O The Universe is accelerating, so that galaxy is moving toward us at higher speed and it will take less than 400 Myr for future photons from that galaxy to reach us. O That galaxy is 400 million light years away from us today. O That galaxy is moving away from us, so today it is more distant from us than 400 million light years. O We are observing that galaxy as it was in the past, and today it is accelerating toward us.arrow_forwardThe Andromeda Galaxy, M31, is the closest large spiral Galaxy to our Milky Way. When we lookat its chemical spectrum, we see that it's hydrogen alpha emission line has an observed wavelength of 655nm. a. Calculate z, being careful with the sign b.

Thank you. Stanford has a linear particle accelerator (SLAC) which is 3 km long that produces electrons with a total energy of 50 GeV. These electrons lead exciting (albeit brief) lives, zooming along the accelerator before slamming into a target to produce other high-energy particles. a. Consider the viewpoint of one of the electrons. From the electron’s point of view, how long is the accelerator? Note that it is possible to answer this question without calculating the electron’s velocity. b. Let’s figure out how fast the electrons are traveling. Start by solving for β = u/c in terms of 1/γ following the trick we used in class. Use the binomial expansion if that is helpful. At what speed does a 50 GeV electron travel? c. The Large Hadron Collider (LHC) at CERN presently accelerates protons to a total energy of 6.5 TeV. Imagine a pulse of light, a 50 GeV electron, and a 6.5 TeV proton race each other along a 3 km distance. The light pulse will surely win…arrow_forward
