The Last Atlas 2 Rocket Launch 174

Fiz Ocelot writes "Reuters reports that the last Atlas 2 rocket was launched on Tuesday. The rocket was the last to launch the old-fashioned way. For this launch, the 120-member team was inside a blockhouse 1,400 feet from the launch pad. It was also the end of an era dating back to the 1950s, when most rockets, including early manned flights, were launched from concrete blockhouses adjacent to the pads."

        The Atlas V launch system uses the same Centaur stage as on the flight proven Atlas III. More operationally efficient than previous systems [ Atlas II and III], the Atlas V significantly reduces the time required to process and prepare each vehicle for launch, thus enabling greater flexibility in meeting customer launch schedule requirements. The modular design and broad performance capability of the Atlas V family maximize responsiveness to customer performance and mission requirements.
      • What's interesting about the Atlas V is that it uses the Russian-built RD-180 main engine, an engine derived from the RD-173 used on Russian rockets.

    This launch signals more than simply the end of that particular series of rocket.

    It also signals the end of NASA's two-decade old "Shuttle + Small Rocket" schema. Hooray.

    To put it another way, about *$#&#*$ time!

    The "Shuttle + Small Rocket" paradigm has kept us firmly in Earth orbit for a generation, and is actually (always was) a step back from the 100-useful-tonnes-to-L.E.O. capabilites of the Apollo-era Saturn V.

    This move is a move back to heavy boosters, and can't come soon enough for those of us [marssociety.org] who are keen on "seeing what's out there".

    In weight terms, with 60's technology (ie the Saturn V) we could have lifted the whole ISS in two shots. With the Shuttle (ie the Winnebago of Space exploration) that has had to be stretched out over a decade, cost far more than it had to, and prevented any other human space-flight programs from going ahead.

    Sending up 100 tonnes, and bringing 90 tonnes back (the Shuttle model) was always a dumb idea. If you go to the trouble of sending 100 tonnes to orbit, you should get more bang for your buck than a measley 10%.

    End of an era, well overdue.

      I think there should be two types of shuttle. First, a personnel shuttle to bring people up and down. Second, for those rare occasions when we need it, a cargo shuttle to bring hardware down (not up, but down). These shuttles, wouldn't be the fixed wing flying brickyards we have now, but a craft with a replaceable ablative heat shield, and parasail/parawing. Cargo would be sent up the way it used to be, as simple rocket payload.
      • If you're going to send the thing up to bring cargo down, it would be a waste not to send cargo up in it too.

      • Couldn't you just dump most cargo into the ocean & pick it up when it lands?

        how much cargo do they bring back anway?

        • You need some sort of heat shield to protect the cargo as it enters the atmosphere. So unless the cargo has its own heat shield built in, you cannot retrieve it without some sort of recovery vehicle.

          Also, why land in the ocean? A parawing is steerable. They could land at the Kennedy Space Centre, or any sizeable airport, or military base.

      ...If you go to the trouble of sending 100 tonnes to orbit, you should get more bang for your buck than a measley 10%.


      A throw-weight of 10% would be fantaastic... (yes, I know you're refering to what's left up there - but it was that line which set me looking for info on payloads vs launchweight).

      - The Saturn V had a take off weight of 3,038,500 kg and could deliver 118,000 kg to LEO - or put differently, a whopping 3.88% of the weight would be payload.

      - The shuttlesystem weights in at 2,029,633 kg (or about 2/3rds of the Saturn V) and can deliver 27,850 kg to 24,400 kg to LEO (used to be more, but was redisgned after the Challenger accident). This puts the shuttle at a measly 1.37% to 1.20% payload left in orbit.

      - The Atlas IIAS had a typical take off weight of 234,000 kg and was capabel of putting 8,610 kg in LEO. A respecable 3.68%, but still below the Saturn V.

      - The Atlas V, which will replace the Atlass IIAS, weights 546,700 kg at lift off, manages 12,500 kg to LEO, which in turns means that just 2.29% of the mass is payload.

      - The Titan II, well known for launching the Gemini spacecraft into orbit, weighted in at 154,000 kg and lifted 3,100 kg to LEO - or 2.01%.

      - The Titan 4, designed to lift 'shuttle sized payloads', weights in at a respectable 886,420 kg, but manages 'only' 17,700 kg to LEO, or about 1.99%.

      - Going tothe russian side, the Soyuz 11A511U2 (for many a year the mainstay of the manned spaceprogram in the Soviet Union), weighted in at 297,800 kg and lifted 7,050 kg to LEO. This places it, with 2.36%, in the same league as american boosters.

      - ESA uses the large, 777,000 kg Ariane 5 EC-A, capabel of placing 16,000 kg in LEO. At a ratio of 2.06% this is no better or worse than most other launchers.

      In short, the Saturn V was a vastly superior rocket - simply because of the economics of scale.

          As for my comment on the echomonics of scale - a bigger rocket will have a better ratio because less weight (realtivly speaking) will be used for the strukture and equipment - leaving more for the payload.

    • I think there are a couple of things missing from your analysis.

      First of all, just because it would take fewer flights doesn't necessarily mean that it would cost less.

      Second, suppose you launched the ISS on two unmanned rockets. Who would put it together? How many shuttle flights would it take to get enough on-orbit person-hours to do the assembly?

      Finally, what about form factor? I haven't been able to find the payload dimensions for the Saturn V, but it might be that the bay in the shuttle is better
