Starship | SpaceX HLS LEO Demo
SpaceX is targeting June 2027 for Starship carrying SpaceX HLS LEO Demo from Launch Complex 39A Starship Pad, Kennedy Space Center, FL, USA, United States of America. Launch Library files only the month, so the date is a placeholder. The date is still provisional and can move.

Celestron Travel Scope 70 mm Refractor
A 70 mm scope on a light tripod that packs into its own backpack, so it's easy to take out. It shows craters on the Moon, Jupiter's four bright moons and the shape of Saturn's rings. The tripod is the weak part, so expect to steady it.

Beginner Dobsonians
A big mirror on a simple rocker mount, with no motors to go wrong. This is a search, not one pick. Compare 130 mm and 150 mm models before you buy.

Beginner refractors
Lighter and quicker to set up than a Dobsonian, but weaker on faint galaxies and nebulae. Worth a look if the scope has to live in a cupboard.

MISSION BRIEF
The Starship HLS pathfinder spacecraft in support of NASA's Artemis III mission in Low Earth Orbit will be a Version 3 vehicle equipped with a docking mechanism, but with no crew cabin or environmental control systems on board. This Starship HLS will launch after the Artemis III Orion has launched into LEO aboard SLS, and has completed its demonstrations with Blue Origin's Blue Moon lander. Once docked, Orion and Starship will spend about a day connected for checkouts and testing.

LAUNCH CORRIDOR
- Due east
- The lowest inclination a direct launch from here can reach is 28.6°. That’s this pad’s own latitude. Flying east also gets the most free speed from Earth’s rotation.
- Due south
- The polar corridor, at 90° inclination, passes over both poles. It gets no help from Earth’s spin, so the same rocket can carry less.
Drag the globe to turn it. The shading is the real terminator, and it moves.
A globe of the Earth centred on Launch Complex 39A Starship Pad at latitude 28.61 degrees north, longitude 80.60 degrees west. Two curved lines leave the pad. The solid gold line runs due east and marks the lowest orbital inclination a direct launch from this site can reach, 28.6 degrees, equal to the pad’s latitude of 28.6 degrees. The dashed cyan line runs due south and marks the polar corridor at 90 degrees inclination. The darkened part of the globe is the night side. The surface wind is from 258° at 7 km/h. That's the cyan arrow at the pad.

Minimum direct inclination 29°. This pad is 29° north of the equator, so a direct launch can't reach an orbit inclined less than 29°. An orbit of inclination i never passes over latitudes beyond ±i. Getting to an equatorial orbit, which geostationary satellites need, takes a 29° plane change at some point in the flight. Inclinations of 29° and up are reachable straight off the pad. The ground here moves east at about 408 m/s with Earth's spin. That's 465 m/s at the equator, falling with the cosine of latitude. A launch due east keeps that head start.

The observed figures are general weather at the coordinates of Launch Complex 39A Starship Pad. They aren’t the launch rules. The operator and the range write those for each mission, and they cover things this forecast doesn’t carry, like electric fields, cloud layers higher up and winds along the rocket’s path. Only the operator publishes them. Wind often stops a countdown, but no number here is a limit for this flight. Nothing here is a go or no-go call. No operator figure was published for this attempt.
