by Marcel F. Williams SLS Block I and Block IB (Credit: NASA)With the successful test launch of Space X's Falcon Heavy, some have questioned why NASA continues to support the development of the Boeing/Orbital ATK Space Launch System (SLS). The Falcon Heavy is now the most powerful rocket in operation with the capability of deploying up to 63 tonnes of payload to Low Earth Orbit (LEO). But next year, NASA will test launch an even more powerful heavy lift vehicle. In its earliest incarnation, the SLS will be capable of deploying at least 70 tonnes of payload to LEO. By the time its Exploratory Upper Stage (EUS) is developed in the early 2020s, the SLS will be capable of deploying more than 105 tonnes of payload to LEO. Future advances or alternatives to the SLS solid rocket boosters also promise to enable the SLS to deploy more than 130 tonnes of payload to orbit. Maximum payload deployment to LEO: SLS Block 2: 130 tonnesSLS Block 1B: 105 tonnesSLS Block 1: 70 tonnesFalcon Heavy: 63 tonnesDelta-IV Heavy: 28.8 tonnesFalcon 9: 22.8 tonnesAtlas-V: 20.5 tonnesBut the Space Launch System will have an additional advantage over other launch vehicles in its ability to ...
