    (In some ways it seems like no progress has been made.
    It has been nearly 50 years since we landed people on the moon,
    and no many going back, or further since.
    But here, one launch, 105 satellites put in orbit, and
    the launch rocket has already done 10 launches and 10
    good landings. No man, but multiple rovers on Mars.
    Some progress is being made.)

    Among the trove of satellites were 44 "SuperDove" cubesats.

    SpaceX has some nice before-and-after photos to mark the 10th launch of
    one of its Falcon 9 rockets, thanks to a satisfied customer.

    A Falcon 9 successfully delivered 105 satellites to orbit Thursday (Jan.
    13), including 44 "SuperDove" cubesats for Planet, a San Francisco-based company that operates the world's biggest constellation of
    Earth-observing satellites.

    The mission, called Transporter-3, marked the 10th launch of this
    particular Falcon 9's first stage — and its 10th landing as well. About
    nine minutes after lifting off from Florida's Cape Canaveral Space Force Station, the booster aced a soft touchdown just a few miles away from
    the launch pad, at SpaceX's Landing Zone 1.

    Planet managed to capture imagery from space of the Falcon 9 both pre-
    and post-flight using SkySats, spacecraft about the size of a mini
    fridge that are capable of resolving features as small as 20 inches (50 centimeters) on Earth's surface. (SuperDoves have a resolution of about
    10 feet, or 3 meters, per pixel.)

    One SkySat photo shows the Transporter-3 Falcon 9 standing at attention
    at Cape Canaveral's Space Launch Complex 40 on Wednesday (Jan. 12), one
    day before liftoff. And on Thursday, Planet posted on Twitter a SkySat
    video of the Falcon 9 first stage shortly after it touched down at
    Landing Zone 1.

    Transporter-3 brought the total number of Planet satellites launched
    over the years to more than 500, the company said in another Thursday
    tweet.

    Many of those spacecraft were lofted by SpaceX.

    "We were thrilled to launch once again with SpaceX, who has now brought
    to orbit a total of 127 Planet satellites across eight launches," Planet co-founder and CEO Will Marshall wrote in a blog post Thursday. "This
    marks our first launch with SpaceX under our new multi-year,
    multi-launch rideshare agreement signed in 2021."

    The 44 newly launched SuperDoves are joining an existing fleet of about
    200 Planet satellites, Marshall added.
