It stands for Temporary Flight Restriction. Source: https://en.wikipedia.org/wiki/Temporary_flight_restriction Presumably the TFR is in place for whatever SpaceX is doing and the radar will be utilized during that same event. So the two things are associated, but one is not because of the other.

A TFR is a Temporary Flight Restriction. My best guess for why SpaceX would include this information in their filing is that the FCC requires that marine radar does not interfere with airplane operations, and what SpaceX is saying is that because of the fact that there are no airplane operations when the radar is transmitting, there is no further need to ...

About 21.3 km/s with 5 stages. To develop this model, I used Kerbal Space Program with Real Solar System & Realism Overhaul. The rocket as built, by stage (dimensions given in diameter x length) 12 x 54 m stir-welded Al-Li semi-stringer construction tanks. 44 sea-level Raptors (330 s sl. Isp, 355 s vac. Isp). Total dry mass of stage: 257 tons. Total ...

Actually it is the opposite. MECO for crew dragon took place sooner as it was lighter. Starlink missions are usually on the edge of the capabilities of Falcon 9 rockets. Each Starlink satellite has a mass of about 260 kg1. Reusable Falcon 9 has a payload limit of 15600 kg. At each Starlink mission, they launch 60 satellites. 60sats*260kg = 15600kg As we can ...

Most probably it is only a reflection from engine flames. Why it cannot be because of heat. The reason behind that is that the part glowing in the picture is the place that has the least aerodynamic interaction. In this video, you can see that the part of the fairing you're asking about is exposed to least aerodynamic pressure. As we can see, it would not ...

How do they monitor the movement of these[...] Sensors a.k.a. radar (for LEO): the US Air - now Space - Force dedicated old Ballistic Missiles Defence Systems for Space Survaillance. This radars are tracking as much objects passing above as possible. [...] to avoid so many possible risks of collisions [...] To make it a bit simple: this measurements are ...
