It's been 11 days since SpaceX last lit up the Space Coast sky with a rocket launch, the longest run between launches in more than a year.

It's not for a lack of trying, though, but bad weather and a scrub as the countdown clock hit 0 last week led to SpaceX taking down a Falcon 9 rocket for a Starlink mission and switching it up with a Falcon 9 to launch a European TV satellite on Tuesday night.

The SES 24 mission flying the ASTRA 1P communication satellite for Luxembourg-based communications company SES is set to launch from Cape Canaveral Space Force Station's Space Launch Complex 40 during a window that runs from 5:35-8:24 p.m. The satellite will service TV markets in Germany, Spain and France.

Space Launch Delta 45's weather squadron forecasts only a 55% chance for good conditions, with liftoff winds and the presence of cumulus clouds a concern. The same issues remain in the event of a 24-hour scrub, worsening to only a 45% chance of good conditions.

If it does launch, the first-stage booster will be making its ninth flight and will aim for a landing downrange on the droneship Just Read the Instructions.

NASA and Boeing are targeting a June 26 return to Earth of the Boeing Starliner from the International Space Station, officials said Tuesday.

Starliner's first crewed mission to the ISS, which had been scheduled to last about eight days, has been extended due to thruster malfunctions and helium leaks.

The spaceship blasted off from Florida atop a United Launch Alliance Altas V rocket on June 5 following years of delays and safety scares—as well as two aborted launch attempts that came as astronauts were strapped in and ready to go.

NASA and Boeing officials said at a press conference that they were looking at a return date of no earlier than June 26 for the two astronauts, Butch Wilmore and Suni Williams, both ex-US Navy test pilots.

NASA aims to construct a lunar base through the Artemis program, a manned lunar exploration initiative. However, the practical reality of what the general public envisions for the space base differs somewhat from well-known science fiction movies. To build a base on the moon using abundant and diverse construction materials, significant transportation costs are involved. All these materials must be launched from Earth using rockets.

Because transporting construction materials from Earth to the moon is costly and time-consuming, local materials must be utilized in order to establish a lunar base.

One promising method for lunar base construction using local materials is microwave sintering, which solidifies lunar regolith (soil) below its melting point.
