A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification) [1] into low Earth orbit (LEO). [2]
On 13 January 2025, Blue Origin conducted their first launch attempt with the vehicle. After several slips in the countdown, the attempt was scrubbed at approximately 3:05 AM EST (0805 UTC). [56] On 16 January 2025, 2:03 AM EST (0703 UTC), New Glenn launched for the first time. [57]
A diagram of the Shuttle-Derived Heavy Lift Launch Vehicle, Block I configuration. The HLV was proposed to be a 4,600,000 pounds (2,100,000 kg) vehicle at liftoff with two 4-segment Space Shuttle Solid Rocket Boosters weighing about 2,600,000 pounds (1,200,000 kg) providing a total thrust of 5,900,000 pounds-force (26 MN) at sea level and the Space Shuttle External Tank weighing about ...
A potential heavy-lift variant (HLV) of the ULV, in theory was capable of placing up to 10 ton class of spacecraft into Geosynchronous Transfer Orbit. It was planned to include: [22] A larger dual S-250 solid strap-on boosters as compared to the S-200 boosters used in LVM3;
In January 2024 NASA announced plans for a first crewed flight of the Orion spacecraft on the SLS, the Artemis II mission, no earlier than September 2025. [93] Included in the above SLS costs above are (1) the Interim Cryogenic Propulsion Stage (ICPS), a $412 million contract [94] and (2) the costs of developing the Exploration Upper Stage (below).
The Shuttle-Derived Heavy Lift Launch Vehicle (HLV) was an alternate super heavy-lift launch vehicle proposal for the NASA Constellation program. It was first presented to the Augustine Commission on 17 June 2009. [30]
A 2006 report, prepared by the RAND Corporation for the Office of the Secretary of Defense, stated that Lockheed Martin had decided not to develop an Atlas V heavy-lift vehicle (HLV). [58]
The model HP-25C, introduced in 1976, addressed that shortcoming through the first use of battery-backed CMOS memory in a calculator, termed continuous memory by HP. Like all early HP calculators, the 25 used the Reverse Polish Notation (RPN) for entering calculations, working on a four-level stack (x,y,z,t). Nearly all buttons had two ...
