Thanks. So for STS 75. I can get the TLE file and load that using the scn editor and then pick the time?

TSS!R deployed

Deployment info

.

For deployment the pitch is -30 and alt 296.32 KM.. Cargo bay away from earth
Not sure about the direction to the sun?
The TSS1R in real life moved. I just have it attached. I suppose I could make it rotate?

STS46 i loaded the TLE and set the date 1 day into the flight 181km

Not sure how to get the different alt. This should be the orbit to launch Eureca.

The altitude depends on the semi-major axis that is computed from the TLE data you based. Here's the formula to get the SMA directly from the TLE

Where:
μ = Gravitational constant of Earth
n = Mean motion (this is the number from the right-most corner in the second row)

Once the SMA is determined, that automatically adjusts the orbital altitude values into Orbiter

Thanks.

grav contant= 9.7
n=15.46403423

Then take that value and load into the scn editor?

If you mean take the value of the calculated Semi-major axis out of the mean motion ( n ), then yes take it and load it onto scn editor. Btw the semi-major axis from the calculation is measured in meters

Also:
μ = 3.986004418 x 10¹⁴

I found I could just change the SMA in the scn to get close to the orbit alt.

This is about 8 hrs into flight.
DAy 1 the Eureca was launched.
Day 3 the TSS was launched

Watching video of the Eureca launch. It looks like the shuttle bay is open towards Earth. Same for TSS

Confused. I have the guidance file set to this:
-30.000 =orbit(425,437,28.45,-1)
But this is what I get

This is from 2010

I like the shuttle orientation. But the orbit seem low and the date is wrong.
from the press kit the orbit should be.
Orbit insertion (230 x 230 n.m.) 425.96km

The shuttle is too heavy to launch itself in a perfectly circular orbit about 400 km in altitude. The initial flight profile of every shuttle launch has its perigee somewhere between 90-110 km to allow the external tank fall into the Pacific or Indian Oceans, and the apogee is always somewhere between 220-250 km depending on the mission.

Therefore, the circularization and raising of the shuttle's orbit is always achieved manually through 1 or 2 OMS burns

Thanks. So what should I set the guidance for?

I made a new ET. It seems at least2 versions of the LWT. Black nose cone and orange

On the orbit I launched and advanced time to day 2 and set the orbit angle and ALt.

I need to make another Columbia. It seems STS 61c, 28,32,35,40 had cross hairs on the nose cone (SEADS Shuttle Entry Air data System)
