How much weight can the Atlas V carry?
Atlas V is also a major NASA launch vehicle. In 2021, ULA announced that Atlas V would be retired after an additional 29 launches….Atlas V.

Is the Delta IV heavy human rated?
Delta IV H first- and second-stage engines can be human- rated. For most HR Delta IV design options studied, the payload performance to the ISS and lunar target orbits provides significant positive margin with respect to Ares I ISS and lunar gross performance.
Is Delta 4 Heavy reusable?
The Delta IV Heavy (Delta 9250H) is an expendable heavy-lift launch vehicle, the largest type of the Delta IV family.
How many pounds of thrust can the Atlas V produce?
The common core booster can provide thrust of up to about 850,000 pounds (3.8 million newtons) at full throttle.
Is the Atlas V Human rated?
The Atlas V, developed by Lockheed Martin, and the Delta IV, developed by Boeing, are products of the US Air Force’s Evolved Expendable Launch Vehicle (EELV) program. Atlas ICBMs were human-rated for five of the seven Project Mercury orbital flights.
Why does the Delta IV set itself on fire?
Just before the Delta IV ignition sequence starts, valves open that control the flow of liquid hydrogen to the engines. Some of that hydrogen seeps out of the engine bells and lingers around the rocket. When the engines roar to life, the excess hydrogen ignites, creating a fireball that chars the booster cores.
How many Delta IV Heavy launches are left?
four remaining
ULA, a 50-50 joint venture between Lockheed Martin and Boeing, has only four remaining Delta IV Heavy rockets in its fleet. All of those are assigned to launch missions for the NRO, with two launches from California (including today’s mission) and the remaining two to launch from Florida.
Is ULA Atlas V reusable?
The Atlas V Commercial Crew configuration was developed specifically for the Boeing CST-100 Starliner spacecraft. The spacecraft crew module has an innovative, weldless structure and is reusable up to 10 times with a six-month turnaround time.
How reliable is Atlas V?
KEY FEATURES. Reliability: The Atlas V has achieved 100 percent mission success since first taking flight in August 2002.
Why does Delta Heavy catch on fire?
On the Heavy, the main CBC’s engine throttles down to 58% rated thrust around 50 seconds after liftoff, while the strap-on CBCs remain at 102%. This conserves propellant and allows the main CBC to burn after booster separation.
What’s the difference between Delta IV and Atlas V?
The adaption of Atlas V as the only EELV would leave a wide “Medium payload” gap between Delta II (5-6 tonnes to LEO) and Atlas V 401/402 (12.5 tonnes to LEO). This could be opportunity to go clean sheet, to extend Delta II (Delta III revisit?), or to redirect a slimmed down Delta IV program.
What kind of PLF is the Atlas V?
The 4-m PLF is a metallic design, configured by adding additional cylindrical plugs to achieve the desired length. The 5-m PLF is a carbon composite bi-sector design manufactured by ULA partner RUAG Space.
How many stages does an Atlas V rocket have?
An Atlas V rocket has a rocket engine, two stages, a solid fuel motor, one interstage, a payload, an aerodynamic nose cap, avionics, a fuel tank and an oxidizer tank.
Are there any problems with the Delta IV?
OMB agrees that the Atlas V and Delta IV systems have not suffered a launch failure to date. However, EELV has two System Interface Specification (SIS) issues. Shock vibration exceeds specifications during the five meter payload fairing separation on the Delta IV. A vibration absorption solution is currently being tested.
