No booster landing legs = lighter, more mass for payload, less drag, less complexity. Eventually plan to catch Starship itself. Obviously the #Mars version needs legs.

Single stage to orbit is such a challenge to actually have any payload. You could achieve SSTO on its own, but without a payload it would be pointless. I don't know if it will ever be possible

The observation has just finished. Taking a quick look at the recording now. The same 12 kbaud r=1/6 Turbo 1115-byte frame modulation and coding has been maintained all the time. Idle Space Packets are "signed" by team members. Congratulations to them and the rest of the team!

A printout of the payload of an idle Space Packet in a Jupyter notebook. There are many names, followed by the words "and many others, including those whose supp[...]". The longest idle Space Packet I have seen is too short to contain the full message.

Here is a picture of the huge solar arrays! Credit: Attaching the Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility at the Kennedy Space Center in Florida in August. NASA/JPL-Caltech

Europa Clipper’s solar arrays are shown with a few people along side. The solar arrays are black with gold lines and are being attached to the spacecraft in the distance in a huge room with white walls and floor.

Ascent Timeline of the Europa Clipper launch.

The spacecraft launch is depicted with a curved line, resembling a logarithmic curve, starting at the bottom left. Nine stages are marked with illustrations.

Liftoff from Cape Canaveral: craft is situated upright.
Max Q: craft is tilted 45° to the right.
Booster separation: boosters are separating from the craft.
First stage separation: upper stage is separating from the craft.
Second Stage Engine Start: craft is firing engine.
Fairing Jettison: fairings are opening in a Y-shape
Parking Orbit: craft is at low angle.
Earth Departure Burn Start: craft is firing.
Earth Departure Burn Cutoff: craft at lower angle.
Europa Clipper Separation: main payload separates from craft.

Structural strengthening, additional fuel, ground hardware, and other factors easily make this a worthwhile endeavour. Reducing fuel margins for landing alone increases payload to orbit. Structural strengthening and landing hardware not being present have similar margin saving benefits.
